摘要

介绍一种枪械制退器熔模铸造工艺设计及试制生产的特点，以及一些质量改进措施。提出了一个“过流金属液补缩”的概念，对于一些同时凝固趋向的零件，从较厚大部位入水，可有效提高零件的内在质量

Abstract

The technological design and the characteristic during trialmanufacture for a stopping device of firearms in lost wax casting as well as some measures for enhancing product quality are introduced. A concept so called \!feeding by over flowing metal melt\" is put forward. Csating with simultaneous solidification trend is improved effectively by metal melt inlet from place of heavy section.\=
