摘要

在真空压铸中

抽真空截止点的确定对压铸件的品质影响很大

过早和过迟将影响压铸的连续生产和不利于减少铸件的气孔。抽真空截止点应设在冲头快压射前 15～ 2 0mm处

真空压铸可以提高铸件的密度 1%以上。

Abstract

Vacuum dead\|point has great effect on quality of die castings in vacuum die casting. Earlier or later set vacuum dead point would effect continuous production and decrease gas hole unfavorably. The vacuum dead\|point should be set up at 15～20 mm far from press shooting of punch. Casting density could be increased up to 1% in vacuum die casting.
