摘要
根据壳体产品的结构特点和要求,在UG平台上设计出复杂侧抽芯结构的分级复合注射模,通过运动分解设计出“T型槽+斜面”的新型复合滑块机构,使3个镶件能同时完成3种不同方向的抽芯;同时采用滑块限位螺丝处预留1段空行程的方法,使滑块在1个液压缸的驱动下实现各镶件之间按顺序分级侧抽芯。实际生产检验表明该注射模具结构合理、工作稳定、自动化程度高。
According to the structural characteristics and requirements of the shell product,a set of hierarchical composite injection mould with complex side core-pulling structure was designed on the UG platform.A new compound slider mechanism of“T groove+inclined plane”was designed through the decomposition of movement,so that three inserts can complete core pulling in three different directions simultaneously.At the same time,the method of reserving a section of empty stroke at the limit screw of the slider was adopted,so that the slider can be driven by only one hydraulic cylinder to realize the sequential side core-pulling among the inserts.The actual production test shows that the injection mould has reasonable structure,stable operation and high degree of automation.
