Design of Injection Mould for Fixing Seat of Automobile Rearview Mirror with Angle Ejector of Front Mould
摘要
Abstract
Based on the analysis of the structure characteristics and material properties of the fixing seat of automobile rearview mirror,the structure scheme and design key points of the injection mould were worked out.Then,an injection mould with two cavities and angle ejector of the front mould was designed.A gating system that combines hot runners with conventional runners,insert-molded forming components,and precise positioning mechanisms were designed to ensure that the mold cavity can be filled and formed smoothly and achieve accurate positioning.A lateral core-pulling mechanism with the combination of the angle pin core-pulling and the angle ejector core-pulling,and the compound push-out mechanism with the combination of the push rod and the push pipe were designed to ensure the smooth core-pulling and demoulding of the plastic parts.In addition,a three-dimensional cooling circuit was designed to shorten the molding cycle of plastic parts.The results show that the mold structure is reasonable and the action is reliable,which can provide a reference for the design of the same type of injection mold.关键词
