The outer guide column assembly is mainly to guide the upper and lower molds to ensure the relative positions of the upper and lower molds; the steel ball bushing can move up and down on the outer guide column. The function of the third spring is to enable the steel ball bushing to move to the uppermost end and be blocked by the bushing block after the mold is detached from the outer guide sleeve. The whole working principle is that the steel ball bushing moves up and down during the downward pressure of the outer guide sleeve. The third spring and steel ball bushing assembly are to reduce the friction surface and are suitable for high-speed processing. The middle guide column is arranged on the lower mold assembly, and its projection position on the horizontal plane is located at the periphery of the inner guide column.
