摘要

通过对汽车后视镜固定座结构特点及材料性能的分析,拟定该注塑模具的结构方案和设计要点,进而设计一套一模两腔带前模斜顶的注塑模具。设计热流道与普通流道相结合的浇注系统、镶拼式成型零件和精定位机构,确保模具型腔能够顺利填充成型并实现精确定位;设计斜导柱抽芯与斜顶抽芯相结合的侧向抽芯机构,以及推杆和推管相结合的复合推出机构,确保塑件能顺利抽芯与脱模;此外,还设计立体式冷却回路,以缩短塑件成型周期。结果表明:该模具结构合理,动作可靠,可为同类型的注塑模具设计提供参考。

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.
