【正文】 output of 60 billion . dollars, Japan, the United States and other industrialized countries die of industrial output value of more than machine tool industry, beginning in 1997, China39。s to high speed, launch technology, precision, security, development of the second stage. Continue to emerge in this process a variety of high efficiency, business life, highprecision multifunctional automatic school to help with. Represented by the number of working places as much as other progressive die and dozens of multistation transfer station module. On this basis, has developed both a continuous pressing station there are more slide forming station of the press bending machine. In the meantime, the Japanese stand to the world39。 in 1997 only 78 million . dollars export mold. At present the technological level of China Die amp。 in the application process planning CAPP technology, basically a blank state, based on the need for a lot of standardization work。 diefunded enterprises branch, the organizational model and professional mold factory is similar to small but the main。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。 Fused Deposition Molding (FDM) and threedimensional printing forming technology (3DP) and so on. xxx大學(xué)畢業(yè)設(shè)計（論文） 16 (2) the surface forming tooling. It refers to the use of spray, chemical corrosion, electroforming and new method for the formation of the cavity surface and a fine pattern technology. (3) Casting forming tooling. There are bismuth tin alloy tooling, zinc alloy tooling, resin posite forming technology and silicon rubber mold molding technology. (4) cold extrusion mold technology and ultramolded shapes. (5) multipoint forming technology. (6) KEVRON steel blanking blanking tooling. (7) mold blank rapid manufacturing technology. Mainly dry sand Mold Casting, Vacuum Mold Casting, Resin Sand Mold Casting Lost Wax Casting, and other technologies. (8) Other aspects of technology. Such as the use of nitrogen gas spring pressure side, discharge, quick die technology, stamping unit technology, and cutting edge technology and solid surfacing edge inserts die casting technology. mold materials and surface treatment technology developed rapidly Industry to the level of mold, material application is the key. Due to improper selection and use of materials, causing premature die failure, which acco unts for more than 45% failure die. In the mold material, monly used cold work tool steel with CrWMn, Cr12, Cr12MoV and W6Mo5Cr4V2, flame hardened steel (such as Japan, AUX2, SX105V (7CrSiMnMoV), etc.。 laminated profile manufacturing (LOM)。 Beijing Beihang Haier Software Ltd. CAXA Series software。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。 in the application of CAE design and analysis of mold calculation, it was just started, most of the game is still in trial stages and animation。s mold industry and its development trend Die amp。 and Switzerland, fine blanking, cold in Germany extrusion technology, plastic processing of the Soviet Union are at the world advanced. 5039。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。s largest the mold into the micronlevel precision, die life, alloy tool steel mold has reached tens of millions of times, carbide steel mold to each of hundreds of millions of times p minutes for stamping the number of small presses usually 200 to 300, up to 1200 times to 1500 times. In the meantime, in order to meet product updates quickly, with the short duration (such as cars modified, refurbished toys, etc.) need a variety of economictype mold, such as zinc alloy die down, polyurethane rubber mold, die steel skin, also has been very great development. From the mid70s so far can be said that puteraided design, supporting the continuous development of manufacturing technology of the times. With the precision and plexity of mold rising, accelerating the production cycle, the mold industry, the quality of equipment and personnel are required to improve. Rely on mon processing equipment, their experience and skills can not meet the needs of mold. Since the 9039。 Mould Industry and manufacturing capacity, China39。 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
