Abstract: As people's living standards are improving,whose requirements for the variety and function of plastic products are also increasing , which enables the rapid development of the plastics industry . Plastics industry has become one of the world's fastest-growing industrial sectors . Preparation is also a variety of plastic products . Injection molding is the most common of which is the most widely used method , which is mainly used thermoplastic molding . It can be molded more complex plastic products disposablly . Injection molding promote the development of the mold industry . Due to the development and application of CAD technology is more widespread and indepth , mold design and manufacturing cycle is shortened , which improves the quality of molds and manufacture of complex mold manufacturing capacity .
In this design , the toy car backplane is the model of design . Proe software is used for its three-dimensional modeling , then determine using a two-cavity mold die structure . In the design , we determine the type of injection molding machine , and the gating system and cooling system . After completion of the mold design , Using computer software to design mold assembly drawing and part drawing .
