1、1. The mold designing and manufacturing The mold is the manufacturing industry important craft foundation, in our country, the mold manufacture belongs to the special purpose equipment manufacturing industry. China although very already starts to make the mold and the use mold, but long-term has no

2、t formed the industry. Straight stabs 0 centuries 80s later periods, the Chinese mold industry only then drives into the development speedway. Recent years, not only the state-owned mold enterprise had the very big development, the three investments enterprise, the villages and towns (individual) th

3、e mold enterprises development also rapid quietly. Although the Chinese mold industrial development rapid, but compares with the demand, obviously falls short of demand, its main gap concentrates precisely to, large-scale, is complex, the long life mold domain. As a result of in aspect and so on mo

4、ld precision, life, manufacture cycle and productivity, China and the international average horizontal and the developed country still had a bigger disparity, therefore, needed massively to import the mold every year . The Chinese mold industry must continue to sharpen the productivity, from now on

5、 will have emphatically to the profession internal structure adjustment and the state-of-art enhancement. The structure adjustment aspect, mainly is the enterprise structure to the specialized adjustment, the product structure to center the upscale mold development, to the import and export structur

6、e improvement, center the upscale automobile cover mold forming analysis and the structure improvement, the multi-purpose compound mold and the compound processing and the laser technology in the mold design manufacture application, the high-speed cutting, the super finishing and polished the techno

7、logy, the information direction develops . The recent years, the mold profession structure adjustment and the organizational reform step enlarges, mainly displayed in, large-scale, precise, was complex, the long life, center the upscale mold and the mold standard letter development speed is higher

8、than the common mold product; The plastic mold and the compression casting mold proportion increases; Specialized mold factory quantity and its productivity increase; "The three investments" and the private enterprise develops rapidly; The joint stock system transformation step speeds up and so on.

9、Distributes from the area looked, take Zhejiang Delta and Yangtze River delta as central southeast coastal area development quickly to mid-west area, south development quickly to north. At present develops quickest, the mold produces the most centralized province is Guangdong and Zhejiang, places su

10、ch as Jiangsu, Shanghai, Anhui and Shandong also has a bigger development in recent years. 2. Mold Present Status of Technology Technical level of China’s mold industry currently uneven, with wide disparities generally speaking, with the developed industrial countries, Hong Kong and Taiwan advan

11、ced level, there is a large gap. The use of CAD / CAM / CAE / CAPP and other technical design and manufacture molds, either wide application, or technical level, there is a big gap between both. In the application of CAD technology design molds, only about 10% of the mold used in the design of CA

12、D, aside from drawing board still has a long way to go; in the application of CAE design and analysis of mold calculation, it was just started, most of the game is still in trial stages and animation; in the application of CAM technology manufacturing molds, first, the lack of advanced manufacturing

13、 equipment, and second, the existing process equipment (including the last 10 years the introduction of advanced equipment) or computer standard (IBM PC and compatibles, HP workstations, etc.) different, or because of differences in bytes, processing speed differences, differences in resistance to e

14、lectromagnetic interference, networking is low, only about 5% of the mold manufacturing equipment of recent work in this task; in the application process planning CAPP technology, basically a blank state, based on the need for a lot of standardization work; in the mold common technology, such as mol

15、d rapid prototyping technology, polishing, electroforming technologies, surface treatment technology aspects of CAD / CAM technology in China has just started. Computer-aided technology, software development, is still at low level, the accumulation of knowledge and experience required. Most of our

16、 mold factory, mold processing equipment shop old, long in the length of civilian service, accuracy, low efficiency, still use the ordinary forging, turning, milling, planning, drilling, grinding and processing equipment, mold, heat treatment is still in use salt bath, box-type furnace, operating wi

17、th the experience of workers, poorly equipped, high energy consumption. Renewal of equipment is slow, technological innovation; technological progress is not much intensity. Although in recent years introduced many advanced mold processing equipment, but are too scattered, or not complete, only ab

18、out 25% utilization, equipment, some of the advanced functions are not given full play. 3. Die trend (1) Mold software features integrated Die software features of integrated software modules required relatively complete, while the function module using the same data model, in order to achieve

19、Syndicated news management and sharing of information to support the mold design, manufacture, assembly, inspection, testing and production management of the entire process to achieve optimal benefits. Series such as the UK Delcams software will include a surface / solid geometric modeling, enginee

20、ring drawing complex geometry, advanced rendering industrial design, plastic mold design expert system, complex physical CAM, artistic design and sculpture automatic programming system, reverse engineering and complex systems physical line measurement systems. A higher degree of integration of the

21、software includes: Pro / ENGINEER, UG and CATIA, etc.. Shanghai Jiao tong University, China with finite element analysis of metal plastic forming systems and Die CAD / CAM systems; Beijing Bei hang Haier Software Ltd. CAXA Series software; Jilin Gold Grid Engineering Research Center of the stamping

22、 die mold CAD / CAE / CAM systems. (2) Mold design, analysis and manufacture of three-dimensional Two-dimensional mold of traditional structural design can no longer meet modern technical requirements of production and integration. Mold design, analysis, manufacturing three-dimensional technolog

23、y, paperless software required to mold a new generation of three-dimensional, intuitive sense to design the mold, using three-dimensional digital model can be easily used in the product structure of CAE analysis, tooling manufacturability evaluation and CNC machining, forming process simulation and

24、information management and sharing. Such as Pro / E, UG and CATIA software such as with parametric, feature-based, all relevant characteristics, so that mold concurrent engineering possible. In addition, Cimarron company Mold expert, Delcams Ps-mold and Hitachi Shipbuilding of Space-E/mold are pro

25、fessional injection mold 3D design software, interactive 3D cavity, core design, mold base design configuration and typical structure . Australian company Mold flow realistic three-dimensional flow simulation software MoldflowAdvisers been widely praised by users and applications. China Huazhong U

26、niversity of Science has developed similar software HSC3D4.5F and Zhengzhou University, Z-mold software. For manufacturing, knowledge-based intelligent software function is a measure of die important sign of advanced and practical one. Such as injection molding experts Cimarron’s software can auto

27、matically generate parting direction based parting line and parting surface, generate products corresponding to the core and cavity, implementation of all relevant parts mold, and for automatically generated BOM Form NC drilling process, and can intelligently process parameter setting, calibration a

28、nd other processing results. (3) Mold software applications, networking trend With the mold in the enterprise competition, cooperation, production and management, globalization, internationalization, and the rapid development of computer hardware and software technology, the Internet has made i

29、n the mold industry, virtual design, and agile manufacturing technology both necessary and possible. 4. Heat Treatment of Die Traditional die and mould design, mainly by experience or semi—experience，is isolated from manufacturing process. Before the design is finalized，the scheme of die and mou

30、ld is usually modified time and again，thus some disadvantages come into being, such as long development period, high cost and uncertain practical effect. Due to strong desires for precision, service life, development period and cost, modern die and mould should be designed and manufactured perfectly

31、. Therefore more and more advanced technologies and innovations have been applied, for example, concurrent engineering, agile manufacturing virtual manufacturing, collaborative design, etc. Heat treatment of die and mould is as important as design, manufacture and assembly because it has a vital ef

32、fect on manufacture，assembly and service life．Design and manufacture of die and mould have progressed rapidly，but heat treatment lagged seriously behind them．As die and mould industry develops，heat treatment must ensure die and mould there are good state of manufacture，assembly and wear—resistant pr

33、operties by request. Impertinent heat treatment can influence die and mould manufacturing such as over—hard and—soft and assembly．Traditionally the heat treatment process was made out according to the methods and properties brought forward by designer．This could make the designers of die and mould a

34、nd heat treatment diverge from each other，for the designers of die and mould could not fully realize heat treatment process and materials properties，and contrarily the designers rarely understood the service environment and designing thought. These divergences will impact the progress of die and mou

35、ld to a great extent. Accordingly，if the process design of heat treatment is considered in the early designing stage，the aims of shortening development period，reducing cost and stabilizing quality will be achieved and the sublimation of development pattern from serial to concurrent will be realized．

36、 Concurrent engineering takes computer integration system as a carrier, at the very start subsequent each stage and factors have been considered such as manufacturing，heat treating，properties and so forth in order to avoid the error．The concurrent pattern has dismissed the defect of serial pattern,

37、 which bring about a revolution against serial pattern． In the present work．the heat treatment was integrated into the concurrent circumstance of the die and mould development，and the systemic and profound research was performed． 總結5.
