注塑模具快速成型技术实用性分析.kdh（Practical analysis of rapid prototyping technology for injection mold.Kdh） Practical analysis of rapid prototyping technology for injection mold Jiang Xiaobo 1,2 1. 、 Southwest University of Science and Technology, Sichuan, Mianyang 621010 2. 、 Loudi Vocational and Technical College, Hunan, Loudi 417000 Abstract the technology of selective laser sintering is the manufacture of the injection mould for the most effective means, but also through further research, improve the technical level of the process and the prototype of the postprocessing, can gain strength, accuracy of qualified metal parts and injection mold injection molding process requirements. Keywords injection mold; rapid prototyping technology; selective laser sintering technology; figure number TG7; document identification code A; article number 1674-6708 (2010) 16-0037-01 At present, a variety of advanced technology in all sectors of high-speed development, the promotion and application of various advanced technology has become an inevitable trend. In the field of manufacturing market competition is increasingly fierce, the traditional design and manufacturing methods of production is becoming more and more difficult to meet the needs of all aspects of high-tech enterprises. One of the advanced manufacturing technology, rapid prototyping technology is to adapt to the market demand and developed at home and abroad in recent years, rapid prototyping technology will be applied to the manufacture of molds, and gradually formed a new rapid tooling manufacturing process, and metal plastic mould rapid manufacturing technology is one of the important research directions at home and abroad at present, including the metal powder for selective laser sintering technology of material processing has become a research hot topic in some developed countries in the world. The basic principle of RP is that any 3D component can be regarded as a superposition of many equal thickness two-dimensional plan
