Insulation Cup Injection Mold Design

Abstract

The key link of changing plastic raw materials into products is the plastics molding process. Plastic processing and mold technology is an evolving integrated subject. Not only with the improving synthesis technology of the polymeric materials, the innovations of the molding equipments, the maturity of processing technology to make progress , but also with the infiltration of computer technology, numerical simulation technology and so on in the field of plastics molding process to access  development. The design through the study of mold and the factory-site study, to analysis the mold structure, meanwhile，drawing on the experiences in the design of programs of scholars from home and abroad to determine the program. Major study is the materials selection of the plastic molds, the application of injection machine, the layout of cavity and the design of regional type, the design of gating system, the design of cooling system, the design of prototyping parts, die-selection, mold design-oriented institutions, the design of ejection mechanism, the check of injection machine, then we can design the injection mold of insulation cup.
