ABSTRACT
Plastic industry is a polymeric material industry established in twentieth Century emerging science and technology foundation, plastic is pided into thermoplastic and thermosetting plastic. Many of the plastic molding process, the injection molding is the main method of thermoplastic plastic molding,molding can be a complex shape of precision plastic parts. The design of the camera shell mold design: a Tasco analysis of product research, determine the process, determine the product in themould layout, determine the parting surface, gating system and other parts of the structure, and the die structure analysis. , the choice of injection machine, calculated the sizes of the molding parts. So the structure can be designed to ensure that the mold strength, accuracy, and reliable operation.Matching the mold structure and the injection machine check. And has drawn up a set of mold assembly drawing and parts drawing with autoCAD. The design of the integrated use of the knowledge base, the design of specialized knowledge "Tasco camera shell mold design", the core of knowledge is the plastic mold, precision mechanical design, mechanical engineering, computer aided design, moldCAD\CAM\CAE.
Keywords: plastic, plastic injection mould, injection molding machine。
