Skeleton die design
Abstract: Injection molding is plastic molding of a kind of important method, it is mainly applied to thermoplastic plastic molding and shaping a complex shape of precision plastic pieces. On analyzing the structure of plastic parts, use requirement, forming quality and mould manufacturing cost, and on the basis of simple structure, shape rules introduced the plastics molding. Design molding parts parts, should according to the characteristics of plastics, plastic pieces of structure and applicable requirements, determine the overall layout, choose mold parting surface demoulding manner, design, determine gating system, platoon excessive system, etc. And then based on the processing and assembly process requirements for molding parts structure design, calculation molding parts work size, shape of key parts were the strength and stiffness checking, and USES the lateral points core-pulling mechanism, make plastics can once moldings. Design the corresponding's side parting core-pulling of injection mould. Finally introduced the working process of the die.
