ABSTRACT
The plastics industry is one of the fastest growing industries in the world, and the plastic injection mold is a kind of fast development. With the development of modern industry, the application of plastic products in various fields such as industry, agriculture and daily life is more and more extensive, and the quality requirement is higher and higher. In the production of plastic products, the high quality of mold design, advanced mold manufacturing equipment, the reasonable processing technology, high-quality mold material and modernization of injection molding equipment are forming an important condition for high-quality plastic parts.
This pletes the design of refrigerator drawer plastic mold, through process analysis of the refrigerator drawer, a pair of a mold cavity of the plastic mold design, including the structural analysis of plastic parts and materials selection, preparation of the mold structure, injection molding machine models of gating system and form the gate design, molding parts the design, mold and determine the selection of standard parts, mold oriented institutions, stripping institutions, exhaust system design, temperature control system design, injection mold material, mold working process, and prehensive use of the standard CAD/CAM system software UG injection mold design module and the establishment of autoCAD parts library is relatively simple part. Through the design and the injection mold has a certain unders
