Mold design模具设计，以下一些英文介绍，可以参考些：）~An integral part of the design of any mold is, of course, the design and detailing of the moldbase. Mold designers need a design tool that is easy to use, performs repeated tasks automatically, produces 3D solid models that update with changes to design parts, and enables capture of in-house design knowledge that can be reused in subsequent designs. The SolutionMuch more than just a library, Pro/ENGINEER Expert Moldbase provides "smart" moldbases and mold components that handle this job of moldbase design, detailing, and creation. When components are placed, operations such as clearance cuts and drilled and tapped holes are automatically performed on the appropriate neighboring plates and components, thereby relieving the mold designer of time-consuming, repetitive. Speed and timing are the keys to success in the E-Age. We are able to rely on our more than a decade of CAD/CAM experience to perform joint preliminary mold development work (ESI) with our customers. We use PRO/E and UG software to design molds and perform computerized processing of mold cores and electrodes. We employ analytical software to simulate mold flow and gain a better understanding of the various situations that may occur when plastic in injected into a mold. This enables us to insure that our design and manufacturing operations will be 100% successful. In order to shorten the time to delivery, we have introduced Synchronous Engineering. This concept greatly shortens the mold development period: We have reduced the average time from receipt of drawings to completion of mold development from 42 working days to only 28 working days.The segregated, departmental approach to product development creates too many obstacles to reduce time-to-market. Data translation between industrial and mechanical design has been such a problem in the past that many companies won't attempt it. Surface continuity becomes a patchwork. Shapes are altered. The stylist's most critical nuances get lost. The limitations to this approach indicate that companies need industrial design and styling functionality to be an integral part of a complete product development process.NX industrial design and styling tools funnel into the larger world of NX product lifecycle management (PLM) solutions. While providing advanced, easy-to-use industrial design capabilities, NX enables companies to develop products from concept through manufacturing within one unified environment. The NX integrated solution set not only eliminates the questions of compatibility and data loss, it circumvents the costs of learning and maintaining multiple systems. Industrial designers retain the freedom to express their ideas while other groups involved in product definition maintain a high level of collaboration and complete process integration. As styling, engineering, packaging, and production work together during the development lifecycle, modifications can be made with the industrial designer's full knowledge of the impact on aesthetic integrityThe associative nature of NX means more than just tight integration between industrial design and engineering. Associativity serves as a foundation for improving product quality, controlling costs, and reducing time to market. Because data integrity is not an issue, the ability to collaborate up front and throughout the development process frees up everyone to focus on their jobs, not their tools. Not only are concepts quickly turned into accurate surface models to define the product, but these definitions can be explored rapidly, with everyone involved, enabling immediate consensus and validation of what-if variations.Modifiable product definitions enhance and increase the speed of communication throughout design, engineering, manufacturing, the extended enterprise, and the supply chain. Since all data is fully associative, when a change is implemented, related applications can automatically update the design to reflect the change. All of this, without restricting industrial designers to the rigid structure of a traditional CAD system.。

Precision injection molding technology of progress Abstract: The polymer precision injection molding technology, impact on precision injection molding of factors, including the precision molds, injection molding machine control accuracy, precision injection process control and other computer control technology. These factors were discussed, and give the relevant solutions, finally introduces some advanced molding technology. Key words: precision injection; injection molding machine precision injection technology; Precision Injection Mold In recent years, as electronics, telecommunications, medical, automotive, and other industries of the rapid development of the high-precision plastic products, and high-performance requirements of growing precision molding technology to continue to progress, new technologies continue to emerge. Precision injection molding products not only require high dimensional accuracy, and low warpage, to write good, but there should also be excellent optical properties. Injection molding is the most important one of the plastic molding methods, including plastics plastics, injection, packing, cooling, and some of the basic process, thus affecting the precision injection molding of many factors. 1, precision molds To produce sophisticated products, precision molds is essential. Die Die in general, the accuracy of the temperature control, mold and die design precision manufacturing, use of plastic shrinkage rate impacts. 1.1 Precision Mold temperature control In general precision injection molding of parts, control mold temperature is to increase productivity. However mold temperature control for precision injection molding of great impact, it affects parts of the contraction, shape, crystallization, such as stress, hot and cold circuit design mold temperature distribution at the request reasonable, precise control accuracy, a die temperature of the best and Lengshuiji control. Mold temperature control and cooling time on the products and their impact on performance of the following factors: (1) melt plastic injection molds and a two-cycle time will be produced in the mold temperature difference fluctuations, and should therefore be to minimize the volatility differential peak. (2) the heat transfer Die Die Die heat through the concrete and die in the transfer out of the media, mold is changed, the media control is the key, the general import and export of its cooling water temperature difference is less than 1 ℃ Application of theory to calculate the average temperature, which can guarantee the stability of heat transfer. Media flow and heat transfer are interlinked, mould surface temperature can be used to control the media flow sensor to compensate for environmental temperature changes caused by mold temperature changes. (3) To enable stable Die Die by the heat absorption and dissemination of balance, the injection molding machine to melt injection to strictly maintain a stable temperature. Die surrounding temperature on the mold had a great impact on the general will be affected to die within the melt convection coefficient of change, so the best set up in the mold surface temperature sensor, die at any time observation of the surface temperature, and keep it stable. (4) changes in the efficiency of heat exchange with mold after a long time in the cooling water pipes and Youban appears in the scale, then the interface to reduce the thermal conductivity should furring timely clearance. 1.2 Precision Die Design and Manufacture Die design is good or bad is to ensure the dimensional accuracy of plastic parts premise, in order to enhance the accuracy of precision injection mold, in the process of designing a computer-aided analysis is necessary, especially for gating system and the flow of heat-conditioning systems mold temperature distribution the analysis. Applications should be as much as possible the use of simulation software and close to the actual loading conditions to melt in the mold simulation analysis in the pouring, cooling, and other non-steady-state process. Die manufacturing quality assurance plastic parts Size is the key to accuracy, precision die is the main characteristic of the manufacturing and assembly operations in addition to polishing, are no manual processing. Die general machining and manual processing ratio is about 6:4 to 7:3, and the machining precision molds and manual processing ratio of 9:1. Die materials and heat treatment is the protection of precision molds in the molding process, the die temperature in the state, which even the mould parts tempered by low temperature, high temperature melt production and will repeat p。

Punching die has been widely used in industrial production.In the traditional industrial production,the worker work very hard,and there are too much work,so the efficiency is low.With the development of the science and technology nowadays,the use of punching die in the industial production gain more attention, and be used in the industrial production more and more.Self-acting feed technology of punching die is also used in production, punching die could increase the efficience of production and could alleviate the work burden,so it has significant meaning in technologic progress and economic value. The article mainly discussed the classification,feature and the developmental direction of the pnnching technology. Elaborated the punching components formation principle, the basic dies structure and the rate process and the principle of design; and designed some conventional punching die:the die for big diameter three direction pipe which solved the problom of traditional machining,the drawing and punching compound die with float punch-matrix,the drawing and cutting compound dies with unaltered press,the compound die for the back bowl of the noise keeper,the design of the compound die which could produce two workpieces in one punching,the bending die for the ring shape part ,the bending die which used the gemel ,automate loading die for cutting, the drawing,punching and burring compound dies with sliding automated loading,the punching die for the long pipe with two row of hole,the drawing die for the square box shape workpiece and the burring die for the box shape workpiece.The punching dies that utilized the feature of the normal punch shaped the workpiece in the room temperature,and its efficiency and economic situation is excellent. The dies here discussed can be easily made,conveniently used, and safely operated.And it could be used as the reference in the large scale production of similar workpieces. CAD and CAM are widely applied in mould design and mould making. CAD allows you to draw a model on screen, then view it from every angle using 3-D animation and, finally, to test it by introducing various parameters into the digital simulation models(pressure, temperature, impact, etc.) CAM, on the other hand, allows you to control the manufacturing quality. The advantages of these computer technologies are legion: shorter design times(modifications can be made at the speed of the computer),lower cost, faster manufacturing, etc. This new approach also allows shorter production runs, and to make last-minute changes to the mould for a particular part. Finally, also, these new processes can be used to make complex parts. Computer-Aided Design(CAD)of Mould Traditionally, the creation of drawings of mould tools has been a time-consuming task that is not part of the creative process. Drawings are an organizational necessity rather than a desired part of the process. Computer-Aided Design(CAD) means using the computer and peripheral devices to simplify and enhance the design process .CAD systems offer an efficient means of design, and can be used to create inspection programs when used in conjunction with coordinate measuring machines and other inspection equipment .CAD data also can play a critical role in selecting process sequence. A CAD system consists of three basic components: hardware, software, users. The hardware components of a typical CAD system include a processor, a system display, a keyboard, a digitizer, and a plotter. The software component of a CAD system consists of the programs which allow it to perform design and drafting functions. The user is the tool designer who uses the hardware and software to perform the design process. Based on the 3-D data of the product, the core and cavity have to be designed first. Usually the designer begins with a preliminary part design, which means the work around the core and the cavity could change. Modern CAD systems can support this with calculating a split line for a defined draft direction, splitting the part in the core and cavity side and generating the run-off or shut-off surfaces. After the calculation of the optimal draft of the part, the position and direction of the cavity, slides and inserts have to be defined .Then in the conceptual stage, the positions and the geometry of the mould components---such as slides, ejection system, etc.----are roughly defined. With this information, the size and thickness of the plates can be defined and the corresponding standard mould can be chosen from the standard catalog. If no standard mould fits these needs, the standar。

Grassland Ecology and Mongolian civil environmental knowledge.（题目）Grassland ecological zone, mainly in the western plains from the northeast, the Inner Mongolia Plateau, the Ordos Plateau, the Loess Plateau, Qinghai-Tibet Plateau, west of the southern edge of the front line, that is, from latitude 51 ° to 28 ° of a broad range stretching 4500 kilometers, accounting for the National Land area of 29%. Mainly distributed in Heilongjiang, Jilin, Liaoning, Inner Mongolia, Ningxia, Gansu, Qinghai, Xinjiang, Tibet and Sichuan provinces and regions inhabited by 10 ethnic minorities, basically constituted from the northeast to the southwest of the half-moon with livestock.In these regions of the 43 ethnic minorities live, there are 19 ethnic groups to engage in animal husbandry, the main representative of the nation has Mongolia, part of the Ewenki and Daur, Kazakhstan, Yugur, Tajik, Kirgiz, Tatar, Tibetan, etc..For the Earth's land area accounted for 47% of the grassland and its ecosystem research has been of concern for people. According to the World Resources Report, 3000-4000 pasture to feed a million nomadic populations and provide a lot of food information, however, due to overgrazing, pasture land, short-term behavior of the policies and grab the most profitable pure economic sense, leading to emergence of grassland desertification and grassland degradation trends. Many experts and steppe grassland study the implementation of the program, and in the world especially in developing countries, study, fully understands the different economic, social and cultural factors that lead to the utilization of the grassland is changing and improving technology are pasture problem is also complicated social problems.According to United Nations Food and Agriculture regarding plant forage research that: "Due to a series of economic, social, political, religious factors, making further expansion of cultivation area of forage is limited. Engaged in the FAO Grassland and fodder crops development in most countries These factors are complex. The work of the future development depends on the rural sociologist or a politician for the cultivation of grass created by the economic and social environmental conditions.World Resources Report, the Indian subcontinent are the deterioration of pastures and overgrazing, drought and mismanagement caused by introduced pastures in recent years, development plans have achieved good results. In sub-Saharan Africa and rangeland management and livestock development, the sector investment, aid mostly ended in failure, it was felt necessary to develop the process of the people take part in local, needs and the local social structure, cultural traditions combine.This understanding of the changes in grassland research for new ideas. However, the current study of grassland ecosystems, from sociology, anthropology perspective on the report of the study are rare. In World Resources Report, in reference to China Ranch situation that 41% of the total land used for grazing, 25% of the grassland degradation, the trend for the risk of soil erosion is accelerated, the loss of productivity, desertification, degradation is faster than regeneration; When talking about the report and the reasons for that:(1) population pressure; (2) 27% of the desertification caused by overgrazing; (3) 50s light agriculture, animal husbandry; (4) the existing sparse and good grassland reclamation for farmland; (5) Urban development has increased the pressure on existing grassland; (6) groups of grazing; (7) of grass and forage crops mismanagement. In fact all of these reasons are related to human factors.States there are about four million square kilometers of grassland area, all over the world accounted for 13.9 percent of grassland, accounting for China's land area of 41.67%, grazing area of third place in the world, second only to Australia and the former Soviet Union. China's pastoral areas should be divided into two regions, the North "nomadic" District and the South "Agriculture" zone, from the Northeast Plain to the Qinghai-Tibet Plateau, the mountains from Hainan to the Yellow Sea, there are grassland distribution, which are the largest area of grassland in Inner Mongolia temperate grassland.However, due to a variety of complex reasons, the use of not only the construction of grassland, my lawn is not only less productive but has 30% of the grass at different levels of degradation Medium. Long-term grassland study did not draw attention, not the 50's before a grasslands national research institutions, the 50's and began farming in the schools in 。

In this connection, the discipline is often known as engineering or applied mechanics. In this sense, mechanics is used to design and analyze the behavior of structures, mechanisms, and machines. Important aspects of the fields of mechanical engineering, aerospace engineering, civil engineering, structural engineering, materials engineering, biomedical engineering and biomechanics were spawned from the study of mechanics.Classical versus quantumThe major division of the mechanics discipline separates classical mechanics from quantum mechanics.Historically, classical mechanics came first, while quantum mechanics is a comparatively recent invention. Classical mechanics originated with Isaac Newton's Laws of motion in Principia Mathematica, while quantum mechanics didn't appear until 1900. Both are commonly held to constitute the most certain knowledge that exists about physical nature. Classical mechanics has especially often been viewed as a model for other so-called exact sciences. Essential in this respect is the relentless use of mathematics in theories, as well as the decisive role played by experiment in generating and testing them.Quantum mechanics is of a wider scope, as it encompasses classical mechanics as a sub-discipline which applies under certain restricted circumstances. According to the correspondence principle, there is no contradiction or conflict between the two subjects, each simply pertains to specific situations. Quantum mechanics has superseded classical mechanics at foundational level and is indispensable for the explanation and prediction of processes at molecular and (sub)atomic level. However, for macroscopical processes classical mechanics is able to solve problems which are unmanageably difficult in quantum mechanics and hence remains useful and well used.Einsteinian versus NewtonianAnalogous to the quantum versus classical reformation, Einstein's general and special theories of relativity have expanded the scope of mechanics beyond the mechanics of Newton and Galileo, and made small corrections to them. Relativistic corrections were also needed for quantum mechanics, although relativity is categorized as a classical theory.There are no contradictions or conflicts between the two, so long as the specific circumstances are carefully kept in mind. Just as one could, in the loosest possible sense, characterize classical mechanics as dealing with "large" bodies (such as engine parts), and quantum mechanics with "small" ones (such as particles), it could be said that relativistic mechanics deals with "fast" bodies, and non-relativistic mechanics with "slow" ones. However, "fast" and "slow" are subjective concepts, depending on the state of motion of the observer. This means that all mechanics, whether classical or quantum, potentially needs to be described relativistically. On the other hand, as an observer, one may frequently arrange the situation in such a way that this is not really required.Types of mechanical bodiesThus the often-used term body needs to stand for a wide assortment of objects, including particles, projectiles, spacecraft, stars, parts of machinery, parts of solids, parts of fluids (gases and liquids), etc.Other distinctions between the various sub-disciplines of mechanics, concern the nature of the bodies being described. Particles are bodies with little (known) internal structure, treated as mathematical 。
