Abstract
In recent years, Chinese automotive industry in the development of high-speed tooling industry, in particular the plastic mold of the ever-increasing demands. In 2007,the plastic mold industry in the entire Die share has risen to 30% .According to the experts predict that in the future years, China plastic mold industry will continue to maintain an average annual growth rate of 10% over the high rate of development. Plastic injection molding is an important method, which is primarily applicable to thermoplastic plastic molding, Molding can be a complex shape of precision plastic parts.This topic takes automotive rear scuff plate plaque as a design model,the injection mold-related knowledge as a basis for elaborate plastic injection mold design process.The design of automotive rear scuff plate plaque for the injection mold design,the use of software UG plastic parts for the solid modeling, plastic parts of the structure analysis for the process. Defined the design, determine the injection molding process as well as some specific details of the calculation and verification. The design of such a structure can be used to ensure reliable Die work to ensure that the other parts of the tie. Finally, use auto mapping two mold assembly drawings and a part drawing . The subject of automotive rear scuff plate plaque injection mold design, and to consolidate and deepen the learning, has been fairly satisfied with the results, achieved the desired design intent.
