摘要

通过提出几种不同的挤压铸造工艺方案

研究了挤压铸造技术成形压缩机活塞的可行性。结果表明

采用直接式挤压铸造以1模4型腔

对保证制件质量

提高生产效率是有利的;采用间接式挤压铸造以液流从制件两端厚壁处进入型腔

模具以侧抽芯拉杆式卸料机构更为合理。

Abstract

The availability of compressor piston in squeezing casting has been researched by comparing different squeezing casting ways. The results show that the direct squeezing casting is favorable for ensuring casting quality and improving production efficiency

while in indirect squeezing casting

liquid alloy should be flowed into the cavity from thick-wall at two-end of the work piece

where the side-drawing-core discharging mechanism is adopted in the mould.
