What role does the guide pillar play during mold production?

There are two main functions, namely guidance and support. The former is to guide the upper mold and the lower mold to align in the correct position. The common problem is that there is no guide pillar guide sleeve. In addition, there can also be some support for the upper membrane column. Considering that the sliding fit between the guide pillar and the guide sleeve is relatively frequent, it is necessary to provide better lubrication performance and open a lubricating oil groove. In order to ensure the working strength of the guide pillar, the diameter of the fixed position should be about twice the diameter of its working position.
