一种压铸模具的挤压销换向机构

A Reversing Mechanism of Extrusion Pin for Die Casting Die

为了消除铸件的气缩孔缺陷,在压铸模具定模侧增加了一种新型局部挤压换向机构。该机构能够在不增加定模模具厚度的情况下应用局部挤压工艺防止铸件热节位置形成气缩孔。该新型局部挤压换向机构不仅设计精巧、节约空间、故障率低、使用可靠,并且构件价格低廉,值得推广应用。

In order to eliminate the blowhole shrinkage defects in die castings,a new type of local extrusion reversing mechanism is adopted on the fixed die side of the die casting die.The local extrusion reversing mechanism can prevent the blowhole shrinkage formation in hot spot position without increasing the thickness of fixed die.This new type of local extrusion reversing mechanism is not only exquisite in design,saving space,low failure rate and reliable in use,but also cheap in component price.Therefore,it is worthy of popularization and application.
