弯销二级侧抽芯机构

Two Stage Side Core-Pulling Mechanism With Curving Pin

对于薄壁制品侧面需要侧抽芯,为了防止侧抽芯时将塑件壁部被夹变形或损坏,因此采用二级侧抽芯。本机构利用弯销的延时侧抽芯特性,用弹簧弹顶进行第一次侧抽芯,弯销进行第二次侧抽芯。

When the mold for product with thin wall need to be pull out from the side, in order to protect the wall from breakage, the mold should be pull out in two steps. Because there is characteristic of delaying pulling out with the curving pin, we use the spring for first pulling out and the pin for second.
