【正文】 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。 laser powder sintering prototyping (SLS)。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。 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。 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。 products factory mold factory or workshop, in order to supply the product works as the main tasks needed to die。 and staff employed after 80 years, expertise, experience lack of handson ability, not ease, do not want to learn technology. In recent years, the brain drain caused by personnel not only decrease the quantity and quality levels, and personnel structure of the emergence of new faults, lean, make mold design, manufacturing difficult to raise the technical level. mold industry supporting materials, standard parts of present condition Over the past 10 years, especially the Eighth FiveYear, the State organization of the ministries have repeatedly Material Research Institute, universities and steel enterprises, research and development of special series of die steel, molds and other moldspecific carbide special tools, auxiliary materials, and some promotion. However, due to the quality is not stable enough, the lack of the necessary test conditions and test data, specifications and varieties less, large molds and special mold steel and specifications are required for the gap. In the steel supply, settlement amount and sporadic users of massproduced steel supply and demand contradiction, yet to be effectively addressed. In addition, in recent years have foreign steel mold set up sales outlets in China, but poor channels, technical services support the weak and prices are high, foreign exchange settlement system and other factors, promote the use of much current. Mold supporting materials and special techniques in recent years despite the popularization and application, but failed to mature production technology, most still also in the exploratory stage tests, such as die coating technology, surface treatment technology mold, mold guide lubrication technology Die sensing technology and lubrication technology, mold to stress technology, mold and other antifatigue and anticorrosion technology productivity has not yet fully formed, towards 10 mercialization. Some key, important technologies also lack the protection of intellectual property. China39。 in the application of CAM technology manufacturing molds, first, the lack of advanced manufacturing equipment, and second, the existing process equipment (including the last 10 years the introduction of advanced equipment) or puter standard (IBM PC and patibles, HP workstations, etc.) different, or because of differences in bytes, processing speed differences, differences in resistance to electromagic interference, working is low, only about 5% of the mold manufacturing equipment of recent work in this task。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。 Mould Industry Status Due to historical reasons for the formation of closed, big and plete enterprise features, most enterprises in China are equipped with mold workshop, in factory matching status since the late 70s have a mold the concept of industrialization and specialization of production. Production efficiency is not high, poor
