Mobile shape so complicated that the mold design has a lot of factors to be considered , in addition to its ejector pin, parting surface, it needs to consider forming the quality of surface finish, and so on. Therefore, we should carefully design the structure of plastic products, find the best design options and choose the molding equipment specifications and models. It is very important, not the straight parts surface, parting surface of choice it is necessary to consider not affect parts of the surface appearance, but also to structural requirements. Pouring system design is also important in the design of the election, pin gate cold-slag well and Z-shape pin were chosen which are solved the problem of products to die. Plastic Parts of the Process model, and further injection structure of the design, preparation of the main components of the injection-processing technologyng. The structure design involve parting plane, cavity layout, old systems, heating cooling systems, the side core pulling mechanism structure, prop up the organization, drawing patterns and the design process of the main work pieces. The later use Creo2.0
