Abstract
    This design of injection mold based on mobile phone shell,  the injection mold was designed by UG NX software, this mold was designd as four-cavity mold plastic mold. determined the structure of the major programs in the mobile phone shell injection mold, including the cavity layout, the determination of surface, the deteminationof gating system and exhaust system,the choice of the push system, the choice of mold materials and the strength calculation, the main forming parts, mold checking the strength of the parts, molding parts, such as the work of the size calculation. And correctly grasp the module MoldWizard mold design skills and methods, completed a three-dimensional modeling and mold assembly. Showd the application capability in 3D mold design. The mold is simple, movement, reliable and had  good exhaust system, etc., in particular, fit the  the complex and thin products.
