Domestic plastic mold market demand for plastic injection molds, where the focus of development of plastic mold. Injection molding plastic molding of a bell, it is mainly applied to the the thermoplastic plastic molding, forming a complex shape precision plastic parts. The issue is the front cover of the mobile phone shell as a design model, the knowledge of the injection mold as the basis, about the process of plastic injection mold design. The design of the phone housing front cover injection mold design, plastic parts using UG software solid modeling, process analysis of the structure of the plastic parts. Clear the design ideas, to determine the injection molding process and to each specific parts of detailed calculation and checking. Such a structure may be designed to ensure that the mold is the use of reliable, ensure cooperation with the other member. And then continue to use the UG its mapping and CAM processing. The subjec
