【正文】 ation of paperless software to threedimensional mold, intuitive feel to the design of mold, using threedimensional digital model can be easily used in the product structure of the CAE analysis, tooling manufacturing evaluation and CNC machining, forming process simulation and the management and sharing of information. Cimatron pany, such as injection mold expert software can automatically generate parting direction in accordance with subtype line and subsurface, generated with the products corresponding to the core and cavity, the realization of the whole moldrelated parts, and BOM is automatically generated for NC drilling process of the form, and capable of intelligent processing parameters, such as processing the results of calibration. (4) mold software applications working trend With the mold in the enterprise petition, cooperation, production and management of globalization, internationalization, and puter hardware and software technology, the rapid development of work industries in the mold allows the virtual design, agile manufacturing technology both necessary and possible. The 5 United States in its 171。 cumulative law by the material continue to increase, the accumulated the necessary physical . Removal of Mold Processing This is the largest mold maker for a class of methods, including machining, EDM (EDM, wire cutting, electrolytic, etc.), chemical processing, such as corrosion. Characterized by the shapesize ponents is removed from the blank material to be redundant. Machining About 90% of the mold by milling, turning, grinding and other machining methods. They are mainly used to mold parts of the final processing aids, as well as working parts of the premold processing and final processing. (1) highspeed machining and milling technology Because the mold cavity often with a large number of freeform surfaces, the traditional handmade has been unable to meet the needs of the linkage of the 2 threeaxis or multiaxis CNC milling machine can solve the maximum extent of the problem in this regard. Therefore, CNC milling and programming tool also naturally bee the focus of advanced manufacturing technology. (2) die cutting and multiaxis joint coordinate processing mode Forming the work surface grinding is a traditional method of finishing with a highprecision, highperformance advantages of degrees. In the mold manufacture, die cut shape is mainly used Ruled Surface finishing punch, die pieces and EDM electrodes and other ponents used. (3) The mold and polishing After surface machining, surface roughness, regardless of their size must be polished again. Mold Polishing Mold current research is still mainly manually or with electric or pneumatic equipment, manually polished, low efficiency, labor intensity, and the quality of instability. China has imported threedimensional surface can be automatic die polishing of the NC Institute mold. Developed humanoid intelligent automatic polishing technology has also been made, but fewer applications. Mold the future research will be towards the special mode, the posite, automation, intelligent direction. Extrusion die, such as research, study mode and laser polishing, EDM polishing, electrochemical polishing, as well as ultrasonic polishing pound polishing equipment and technology. EDM Mold processing technology of electricity mainly refers to wire cutting, EDM, piercing and electrolysis processing. (1) WEDM Cutting EDM spark discharge using metal melting or vaporization, and melting or vaporization of the metal to get rid of in order to achieve a variety of shapes metal parts processing. Wirecutting for processing small precision, plex shapes, materials, special die parts, the more plex shapes, small precision dies, carbide 3 dies in particular, its economic effects has bee more significant. MicroEDM and Wire Cutting walking is the main development of hot spots in recent years. (2) Cavity EDM EDM cavity forming a replication process, it is the use of spark discharge method to copy the shape of tool electrode in the blank mold cavity formed. EDM cavity mold in today39。 1 中文 4411 字 英文資料 Modern Mold Manufacture And Development Of Cuttingedge Technology Materials based on the role of mold in different ways, can be summed up modern processing methods for mold removal method, molding method and the cumulative three types of law. Removal Act mold material was removed and the necessary forms。 forming method
