Plastic Injection Mold Design of a Rearview Mirror of an Automobile

The time，The mould is an important technical equipment in the industrial producing and an important basis in kinds of department’s developing in nation’s economy. Because of the rapid development of China’s plastic industry , especially in the aspect of engineering plastic. The plastic mold will develop more rapid than the whole mould industry in our country in the future. With the CAD/CAE/CAM software’s fast developing in intelligence, the plastic work pieces, the mould’s 3D design and its shaping process’ computer aided engineering will play an important role in our country’s plastic mould industry more and more. The subject of this design is “The Plastic Injection Mould Design of a Rearview Mirror of an Automobile”. Analysis the manufacturing-ability for the rearview mirror, realizing its technical specifications and coal the practicality cases of production and manufacture-ability will be done to design the injection plastics mould. The plastic injection mould design includes the injection molding technological process, the parting surface design, the cavity design, the core design, the particular structural design, the parts craft analysis and the choice for standard components, etc.

It is detailed in introducing the dividing plane, cavity disposing, the gating system, the gas withdrawal system, the heating or cooling system, the pack out or divorce mechanism，and the design process for the mostly parts. The new design concepts and new design methods are adopted in the design process. Lower costs, shorten production cycles and increased productive efficiency, as using three-dimensional CAD solid model and a 3D CAD knowledge-based assisted injection mould design system for all phases of the product-mould development life cycle.
