　　The importance of reasonable selection of ejection position for zinc alloy die casting

　　Zinc alloy die casting production needs to use two major tools, respectively die casting mold and die casting machine, die casting mold is divided into two parts, in the production, the dynamic mold and the fixed mold is closed, after the die casting cooling molding, the dynamic mold and the fixed mold will be opened, and then the zinc alloy die casting, zinc alloy die casting needs to be removed by the ejector rod. It is very important to choose the ejection position of the die casting reasonably.

　　The ejection position of zinc alloy die casting parts should be selected in a place where the pressure of the die casting parts is uniform and smooth, and the marks left by the die casting parts should not affect the appearance of the die casting parts. Zinc alloy die-casting cracks, deformation, surface marks and other defects, may be due to improper selection of ejection position, a qualified product, may be in the work to fall short, so it is a pity.
