在塑件斜面上成形孔并嵌入环形件,这样就产生了侧向分型与环形嵌件定位的重双问题。一般侧向分型大多采用斜导柱、斜滑块、弯销等抽芯机构,但这些方法对于环形嵌件的定位并没有优越性,且结构复杂,加工成本也高,不利于小批量或试生产的要求。下面将介绍几种在塑件斜面上带环形嵌件的抽芯机构。一.模内手动抽芯机构模内手动分型抽芯机构(图1)工作时,首先把环形嵌件(件2)套在手动抽芯机构的
Forming the hole in the plastic bevel and embedding the ring member results in a double problem of lateral sub-type and ring insert positioning. Most of the lateral classification usually use inclined guide column, inclined block, bent pin and other core pulling mechanism. However, these methods have no superiority for the positioning of the annular insert, and the structure is complex and the processing cost is also high, which is not good for small batch or Trial production requirements. In the following, we will introduce several core pulling mechanisms with ring inserts on the bevel of a plastic part. One manual core pulling mechanism within the mold Manual split core pulling mechanism (Figure 1) work, the first ring insert (2) in the manual core pulling mechanism
