The design of molding process and injection mold of automobile lamp holder
Abstract: Plastic mold is one of the important equipment of plastic forming, plays an important role in the plastic products manufacturing process, which directly affects the quality, performance. In this paper, through the reasonable arrangements for automobile lamp holder molding process and the design of injection mold, introduces the basic process of automobile lamp holder injection molding, especially the structure and working principle of single injection mold parting surface. Analysis of structure and shape of the parts and 3D modeling, the performance of ABS material, comprehensive selection of a reasonable forming method, then design and analysis of injection. The mold uses bevel pillar mold core-pulling mechanism and ejecting mechanism solves the demoulding problem of the plastic parts with some porous around, the die structure is compact, Pushing mechanism reliable, convenient installation and operation, the molding of good quality. Using UG and CAD to the die assembly drawings, the main forming parts diagram and other non-standard parts drawing, check the injection molding machine correlation dimension and molding parts dimension theoretical calculation. According to the product requirement, and ultimately determine the overall scheme of mould design.
