Title A certain type of socket pan injection mold design
Abstract
The plastic molding is all kinds of plastic raw materials will be made into need to the shape of the process. This design through in one type of socket pan injection molds design, according to the characteristics of plastic parts PC material and product use requirement of product process analysis. After analysis of forming scheme design, mold design to lay the foundation.
Injection mould including formwork, the injection molding machine, injection molding systems, molding parts, demoulding mechanism and cooling units. The structure of the components of molding and size calculation is the core content of this design. And molding parts size calculation is the main basis of the average product material shrinkage.
In addition to design the computation part, the parameters of mould of checking and mold assembly is also cannot be neglected in the content. Finally through the finite element analysis software to mold work force situation to carry on the analysis, ensure the rationality of the design.
