【正文】 ily 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。 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。 Mould Industry Association, overall planning, focus on research, crosssectoral, interdepartmental management difficulties are many. Mold is suitable for small and medium enterprises organize production, and our technical transformation investment tilted to 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 advanced industrial countries and regions, the proportion of plastic forming die die general of the total output value 40%. Most of our stamping die mold for the simple, singleprocess mode and meet the molds, precision die, precision multiposition progressive die is also one of the few, die less than 100 million times the average life of the mold reached 100 million times the maximum life of more than accuracy 3 ~ 5um, more than 50 progressive station, and the international life of the die 600 million times the highest average life of the die 50 million times pared to the mid 80s at the international advanced level. China39。s, the United States, Japan and other industrialized countries die industry output value has exceeded the machine tool industry, and there are still rising. Production technology, according to the International Association predicts that in 2020, the product best pieces of rough 75%, 50% will be finished mold pleted。 from Japan in the early 80s will be threedimensional cad / cam system for automotive panel die. Currently, the physical parts scanning input, map lines and data input, geometric form, display, graphics, annotations and the data is automatically programmed , resulting in effective control machine tool control system of postprocessing documents have reached a high level。s mold standard parts production, the formation of the early 80s only smallscale production, standardization and standard mold parts using the coverage of about 20%, from the market can be assigned to, is just about 30 varieties, and limited to small and medium size. Standard punch, hot runner ponents and other supplies just the beginning, mold and parts production and supply channels for poor, poor accuracy and quality. Die amp。s AQ325L, AQ550LLSWEDM have driven fast response, transmission and high positioning 15 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 42020r/min. Italy RAMBAUDI39。 laminated profile manufacturing (LOM)。s mold industry is relatively backward and still could not be called an independent industry. Mold manufacturer in China currently can be divided into four categories: professional mold factory, professional production outside for mold。s mold industry and its development trend Die amp。s industrial output value has exceeded the mold machine tool industry output. According to statistics, home appliances, toys and other light industries, nearly 90% of the parts are integrated with production of chopsticks。 Mould Industry and manufacturing capacity, 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。 used a new type of hot work die steel American H13, Sweden QRO80M, QRO90SUPREME, etc.。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
