Abstract

Aiming at the problems that the distance between the existing section cooling channel structure and the cavity wall is not constant, a type of runway section cooling channel structure was proposed. Based on the traditional channel design method, the channel design method of "line -plane-body" was improved. Using the Cosmetic bottle caps as research object, the runway cross section type cooling structure was designed, and the injection molding process parameters were optimized through orthogonal test, and obtained the optimal combination of process parameters, the results show that compared with before optimization of process parameters, plastic parts warp distortion was reduced by 11.6%, finally through the hot solid coupling analysis, show that the structure of the thermal stress distribution uniformity, Reduce the phenomenon of stress concentration in the water channel of the mold insert, ensure the service life of the insert, and have a wide range of applications in the structure of plastic parts with double wall surface.
