摘要

介绍了利用酚醛树脂砂在 2ZZ8640型热芯盒射芯机上

制造空心气门挺杆的铸造新工艺。为了获得合格的铸件

选用了缝隙式和高梯形式相结合的浇注系统 ;在工装设计上根据经验在保证壳型射满的条件下

射砂嘴尽量少

分布要均匀

并在水冷射砂板上设计导砂板 ;为了实现小批量生产设计了一条简易流水线。

Abstract

A new technology of cast hollow valve jib using phenol resin sand in 2ZZ8640 hot box shoot core machine is described. In order to product qualified casting

combined pressure gate with high trapezium gating system is selected. In condition of ensuring shell to be shot fully

shooting meatus should be fewer and well distributed and guide board is designed on water cooling shoot board.
