摘要
分析了后防护罩塑件的工艺特点,介绍了该塑件注射模结构设计和工作过程。该模具通过自行设计的唧嘴与尼龙开闭器等零件的配合,控制开模运动顺序,实现了凝料和塑件的自动分离。通过斜销和液压系统驱动滑块,完成了塑件四周的侧向抽芯。模具结构合理,运行可靠。
The technological characteristics of the back housing were analyzed. The structural design and operating process of the injection mold for the part were introduced. The coordinate of specially designed sprue bushing、nylon shutters and so on was used to open the mold sequentially and realize automatic separation of running system and the molding. Sliders （drove by angle pin and hydraulic system） were used for core-pulling. The mold structure is rational and safe in operation.
