Injection, extrusion, die casting and pressure molding of plastic products is still the main way of forming. With the art of raising the level of modern industrial structure more complex plastic products, which makes injection molding technology has been more widely used. Obviously mold design also will mention the important role. With modern design in the CAD / CAM technology, which makes computer simulation of universal design in injection mold design and development played a more crucial role. The basic composition of injection molds: the fixed mold body, the dynamic model agencies, casting systems, guiding device, top the body, core body cooling and heating equipment, exhaust system. In this paper, CAD / CAM technology uses Unigraphics software injection mold CAD / CAM methods and means and to clock back cover design, for example, analysis of the alarm clock back cover parts of the structure and process, determine the injection molded plastic parts program and were related to injection mold design, calculation and computer simulation to achieve through the plastic injection mold complex structure and the preliminary design of relevant institutions.Using autocad on the injection mold parts for the relevant size and surface accuracy of the detail design. Finally, mastercam designed to convert between the two enables the simulation of NC machining process simulation of forming process．Keywords：Injection Mold CAD/CAM UGSignature of advisor:
