摘要

介绍了防止熔模铸件变形的几种措施。针对易变形件要从第一道工序-射蜡就采用在蜡模中放入阻碍物限制收缩变形、开浇道根后粘浇道

压蜡后在水中冷却等有效措施

使蜡模处在一个良好的质量状态之下。大量生产实践证明

这些预防措施是有效并且十分必要的。

Abstract

Some countermeasures of preventing the deformation of castings in investment casting were expounded.Aiming at easily-deformed castings

the effective measures should be adopted from the first procedure

wax injection

to render the wax pattern in a desirable quality condition.The practical production verified that these countermeasures are effective and necessary for preventing the deformation of investment casting.
