【正文】 pacity, China39。s mold industry currently uneven, with wide disparities. Generally speaking, with the developed industrial countries, Hong Kong and Taiwan 8 advanced level, there is a large gap. The use of CAD / CAM / CAE / CAPP and other technical design and manufacture molds, both 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 CAD, aside from drawing board still has a long way to go。 in the mold mon technology, such as mold rapid prototyping technology, polishing, electroforming technologies, surface treatment technology aspects of CAD / CAM technology in China has just started. Computeraided technology, software development, is still at low level, the accumulation of knowledge and experience required. Most of our mold factory, mold processing equipment shop old, long in the length of civilian service, accuracy, low efficiency, still use the ordinary forging, turning, milling, planing, drilling, grinding and processing equipment, mold, heat treatment is still in use salt bath, boxtype furnace, operating with 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 plete, only about 25% utilization, equipment, some of the advanced functions are not given full play. Lack of technology of highquality mold design, manufacturing technology and skilled workers, especially the lack of knowledge and breadth, knowledge structure, high levels 9 of pound talents. China39。 Mould Industry Structure in Industrial Organization China39。 township mold business, and professional mold factory is similar. Of which the largest number of firstclass, mold production accounts for about 70% of total output. China39。s software will include a surface / solid geometric modeling, engineering drawing plex geometry, advanced rendering industrial design, plastic mold design expert system, plex physical CAM, artistic design and sculpture automatic programming system, reverse engineering and plex systems physical line measurement systems. A higher degree of integration of the software includes: Pro / ENGINEER, UG and CATIA, etc.. Shanghai Jiaotong University, China with finite element analysis of metal plastic forming systems and Die CAD / CAM systems。s software can automatically 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 and other processing results. (3) mold software applications, working trend With the mold in the enterprise petition, cooperation, production and management, globalization, internationalization, and the rapid development of puter hardware and software technology, the Inter has made in the mold industry, virtual design, agile manufacturing technology both necessary and possible. The United States in its 21st 14 Century Manufacturing Enterprise Strategy that the auto industry by 2020 to achieve agile manufacturing / virtual engineering solutions to automotive development cycle shortened from 40 months to 4 months. mold testing, processing equipment to the precise, efficient, and multidirection (1) mold testing equipment more sophisticated, efficient Sophisticated, plex, largescale mold development, testing equipment have bee increasingly demanding. Precision Mould precision now reached 2 ~ 3μm, more domestic manufacturers have to use Italy, the United States, Japan and other countries in the highprecision coordinate measuring machine, and with digital scanning. Such as Dongfeng Motor Mould Factory not only has the capacity 3250mm 3250mm Italian coordinate measuring machine, also has a digital photography optical scanner, the first in the domestic use of digital photography, optical scanning as a means of spatial threedimensional access to information, enabling the establishment from the measurement of physical → model output of engineering drawings → → the whole process of mold making, reverse engineering a successful technology development and applications. This equipment include: secondgeneration British Renishaw highspeed scanners (CYCLON SERIES2) can be realized and contact laser probe plementary probe, laser scanner accuracy of , scanning probe contact accurac y of mm. Another German pany GOM ATOS portable scanners, Japan Roland39。s highspeed milling, the processing range of up to 2500mm 5000mm 1800mm, speed up 20500r/min, cutting feed speed of 20m/min. HSM generally used large, mediumsized mold, such as motor cover mold, die casting mold, large plastic surface machining, the surface precision up to . 4. 3 rapid economic modeling techniques Shorten the product development cycle is an effective means of market petition to win one. Compared with the traditional mold process, fast economic modeling technology is a short molding cycle, the characteristics of low cost, precision, and life can meet the production needs, overall economic efficiency is more significant in the mold manufacturing technology, specifically the following main technology. (1) rapid prototyping and manufacturing (RPM). It consists of threedimensional laser lithography (SLA)。 used a new type of hot work die steel American H13, Sweden QRO80M, QRO90SUPREME, etc.。 can use the coating are: TiC, TiN, TiCN, TiAlN, CrN, Cr7C3, W2C, etc., while heat from the air treatment means to the development of vacuum heat treatment. In addition, the current stre
