Abstract

Abstract:

An interchanging structure design was adopted for the plastic parts of a car seat side guard plate（with and without a button hole） mold structure with a fixed mold and a moving mold. Such a design solved the problem that the same mold could produce two types of plastic parts with different structures， improve the use value of the mold， and reduce the cost of product research and development for products. Through the design of convenient interchanging structure of a mold insert， the removal of mold， mold installation time， and labor costs were greatly reduced. The abnormal⁃shaped inclined top core⁃pulling mechanism and the straight top core⁃pulling mechanism could cooperate to help the conventional inclined top core⁃pulling mechanism to complete the normal demolding of the plastic parts when the design position was insufficient.

Key words: insert interchange structure, atypia, inclined top core?pulling mechanism, straight top ejector mechanism
