Especially in the production of plastic products, plastic mold and widely applied, is becoming more and more prominent in the position in all kinds of mold, the wastepaper basket mould design is also become one of the representative of mould. Markets on the waste paper basket shape, different function, cartoon version, version of the furniture, which can attract customers attention, cause the customers desire. Wastepaper basket structure of this design is simple, but to consider in the design of its application, also did some surface accordingly, so the surface structure, calculation and more. This design elaborated the mould CAD/CAE technology characteristic and the application of the advanced manufacturing mode in the mold industry. In injection mold design, can be convenient, accurate and fast query and calculate all the design parameters, it is an important technology of the mould design intelligent, rapidness method.Plastic is the emerging materials developed in the 20th century, due to the widely used replacing part of the metal, wood, leather and silicate has the natural material such as, become indispensable in modern industry and life a kind of artificial synthetic material, and compared with wood, metal, silicate three traditional materials together, become one of the four important raw materials in modern industrial production, and injection mold is one of the types of fast development, it is with the development of petroleum industry and should be born, at present plastic parts already in almost all industrial sectors and different areas of the Peoples Daily life. With mechanical industry electronics industry, aviation industry, instrument industry and supplies the development of industry, more and more demand for plastic molding parts, quality requirements also more and more high, this requires molding plastics mold The level of development, design and manufacture should be higher and higher. Therefore, the research injection mold to understand the plastic product production process and improve the quality of products has great significance.In recent years, many new methods of plastic molding process. Such as injection molding technology of flow condensation forming, thermosetting plastic injection molding, exhaust injection molding reaction injection molding, and a variety of plastic injection molding, common molding process of injection molding, compression molding, transfer molding, extrusion molding, blow molding, vacuum pressure molding (blister), etc. Through the correct analysis of plastic forming process, designed a pair of one module and one cavity plastic mold. Mold in the geometric shape and size of the plastic parts called molding parts, including screw, water mouth, cavity, core, ejecting board, dynamic template, the suspension loop, the design and machining process of guide pillar and so on. Molding parts in direct contact with the plastic at work, at a certain temperature melt under high temperature and high pressure, so there must be a reasonable structure, high strength and rigidity, good wear resistance, the correct geometry, high dimensional accuracy and low surface roughness. Important parts of the process parameters selection and calculation, and extrusion outfit, inject system and other structures of the design process.According to the calculation in the design of plastic existing data and the known design parameters, determine the overall design scheme of the wastepaper basket plastic injection mould. Performance of the technology of plastic waste paper basket was analyzed, and the determination of the selection of injection machine, the parting surface, cavity number, molding parts design, the design of gating system design, demoulding mechanism. According to the calculation results finally completed the plastic waste basket injection mould structure design. In addition, also including the mold parts, and use the advanced software to its processing part of the generated files directly. This article emphasizes the use of modern computer aided design and manufacturing technology, domestic and foreign famous software such as aided design, not only ensure the quality of the products, also greatly improved the manufacturing productivity, shorten the cycle of product updates.
