【正文】 large and medium enterprises, small and medium enterprise investment mold can not be guaranteed. Including product factory mold shop, factory, including, after the transformation can not quickly recover its investment, or debtladen, affecting development. 11 Although most products factory mold shop, factory technical force is strong, good equipment conditions, the production of mold levels higher, but equipment utilization rate. Price has long been 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。 Jilin Gold Grid Engineering Research Center of the stamping die mold CAD / CAE / CAM systems . 13 (2) mold design, analysis and manufacture of threedimensional Twodimensional mold of traditional structural design can no longer meet modern technical requirements of production and integration. Mold design, analysis, manufacturing threedimensional technology, paperless software required to mold a new generation of threedimensional, intuitive sense to design the mold, using threedimensional digital model can be easily used in the product structure of CAE analysis, tooling manufacturability evaluation and CNC machining, forming process simulation and information management and sharing. Such as Pro / ENGINEER, UG and CATIA software such as with parametric, featurebased, all relevant characteristics, so that mold concurrent engineering possible. In addition, Cimatran pany Moldexpert, Delcam39。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 TALYSCAN150 multisensor, respectively Threedimensional scanner with high speed, lowcost and functional posite and so on. (2) CNC EDM Japan Sodick linear motor servo drive using the pany39。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)。 laser powder sintering prototyping (SLS)。 used a new type of hot work die steel American H13, Sweden QRO80M, QRO90SUPREME, etc.。 panel drawing die used HT300, QT602, MoCr, MoV cast iron, largescale mold with HT250. more regular use of Precision Die Hard Steel Results YG20 and other alloys and carbide. in the mold surface treatment, the main trends are: the infiltration of a single 17 element to the multielement peration, plex permeability (such as TD method) development。 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
