摘　　要：通过对护栏支架的结构特点进行工艺性分析,设计了一种一模四腔侧浇口注塑模,并通过斜导柱侧抽系统实现模具的侧向分型与抽芯。利用Moldflow有限元分析软件对塑件的充模过程进行了模拟,验证了所设计的浇注系统可以满足对塑件成型质量和成型效率的要求。Moldflow分析软件在塑料模具设计过程中的正确应用可以有效降低模具设计的成本和周期,也为同类零件的模具设计提供了可靠参考。Through the process analysis of the structural characteristics of the guardrail bracket,a one-mold four-cavity injection mold with side-gate is designed.The lateral parting and core pulling of the mold are realized through the side pulling system of the inclined guide pillar.Finite element simulations of mold filling and cooling process are carried out by using Moldflow analysis software.The simulation results show that the designed gating system and cooling system can meet the requirements of molding quality and efficiency of the plastic parts.The correct application of Moldflow analysis software in the process of plastic mold design can effectively reduce the cost and cycle of mold design,and also provide a reliable reference for the mold design of similar parts.
