摘要

铸件带有内侧凹时

其成形和抽芯是模具设计的难点

采用弯销内抽芯结构

可有效地解决。该模具为一模一件

一次分型

缝隙式浇口进料

弯销内抽芯

圆弧截面推杆推件。经实践后调整的参数:内浇道处金属液的流速为18m/s

压铸温度为670～720℃

铸件留模时间为12s

压射比压为30～50MPa。

Abstract

Inside concave formation and core-pulling are the difficult point in mould design of the castings with inside concave.The above problems can be effectively eliminated by adopting structure with dog-led cam for inside core-pulling.The mould is designed a mould to apart

in which once-parting and pouring by slit runner were used with dog-led cam for inside core-pulling and pulling part by arc-section push rod.The practical processing parameters of die castings are as follows:filling velocity of 18m/s

pouring at 670～720℃ and holding for 12s as well as injection specific pressure of 30～50MPa.
