汽车喇叭支架双色注射模设计

Design of 2K Injection Mold for Automobile Speaker Bracket

通过汽车的喇叭支架塑胶件结构分析,介绍了排位2+2的布局,第一色和第二色放缩水方法技巧,配合机械手取件平移放入第二色型腔内;普通注塑机实现双色高效率注射成型,采用双色热流道系统缩短成型周期,提高生产效率,在非操作侧加装副注射咀,大大降低人工成本和注塑生产成本;阐述了模具结构设计要点和移动互换座安装五金端子动作步骤,第二色PP+GF硬胶型腔做避空,解决第二色TPE容易起飞边等问题,可为模具设计人员提供参考借鉴。

Through analysis for the Automobile Speaker bracket:2+2 mold layout introduce,method and skill for the shrinkage of first shot and second short,take the parts and translate them into the second short by robert,to achieve 2K high efficiency injection molding for the ordinary injection molding machine,use 2k hot runner system to shorten the cycle time and improve the productivity,add assistant nozzle in the non-operating side to reduce the cost of labor and injection molding machine.The key points of mold structure design are described.Add clearance for the second short,solve the flash issues for the second short,provide reference to the designer.
