摘 要  Abstract Injection molding is one of the main methods for thermo plastics, and it can once-form delicate plastic members with sophisticated shape. In this design, the knowledge of injection mold design and related mechanical design are mainly used. The design process of a injection mold is analyzed, that is, the analysis of injection molding, the selection of the injection molding machine and the check of the related parameters of it, the structural design of the mold,, the related calculation of the injection mold design, the determination of the overall size of the mold and the drawing of the sketch, the drawing of the assembly diagram of the mold structure and the parts diagram, and so on.. the design includes the choice of the molding location and the parting surfaces, the determination of the number of the mold cavity, the layout arrangement and the runner layout of the cavity, as well as the choice of the gate location, the structural design of the mold parts、the core-pulling mechanism、the gating system、the ejection mechanism and so on.Design process mainly uses the Pro/E 3D part drawing and according to the design drawing of the mould core and cavity, and basic mold rack and so on, then use Auto CAD 2D assembly drawing and parts drawing, at last, by check, for the whole structure to improve its stability and reliability.
