CAXA Series software。 Jilin Gold Grid Engineering Research Center of the stamping die mold CAD / CAE / CAM systems . (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, 重慶理工大學(xué)畢業(yè)論文 文獻(xiàn)翻譯 21 Delcam39。s Psmold and Hitachi Shipbuilding of SpaceE/mold are professional injection mold 3D design software, interactive 3D cavity, core design, mold base design configuration and typical structure . Australian pany Moldflow realistic threedimensional flow simulation software MoldflowAdvisers been widely praised by users and applications. China Huazhong University of Science have developed similar software and Zhengzhou University, Zmold software. For manufacturing, knowledgebased intelligent software function is a measure of die important sign of advanced and practical one. Such as injection molding experts Cimatron39。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 Century Manufacturing Enterprise Strategy that the auto industry by 2021 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 重慶理工大學(xué)畢業(yè)論文 文獻(xiàn)翻譯 22 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 accuracy of mm. Another German pany GOM ATOS portable scanners, Japan Roland39。s PIX30, PIX4 desktop scanner and the United Kingdom Taylor Hopson39。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 AQ325L, AQ550LLSWEDM have driven fast response, transmission and high positioning accuracy, the advantages of small thermal deformation. Switzerland Chanmier pany NCEDM with PE3 adaptive control, PCE energy control and automatic programming expert systems. Others also used the powder mixed EDM machining technology, microfinishing pulse power and fuzzy control (FC) technologies. (3) highspeed milling machine (HSM) Milling is an important means of cavity mold. The lowtemperature highspeed milling with the workpiece, cutting force is small, smooth processing, processing quality, processing efficiency (for the general milling process 5 to 10 times) and can process hard materials (60HRC) and many other advantages. Thus in the mold processing more and more attention. Ruishikelang pany UCP710type fiveaxis machining center, machine tool positioning accuracy up to 8μm, homemade closedloop vector control spindle with a maximum speed 42021r/min. Italy RAMBAUDI39。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 重慶理工大學(xué)畢業(yè)論文 文獻(xiàn)翻譯 23 cover mold, die casting mold, large plastic surface machining, the surface precision up to . 3. 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, o
