摘要

铝合金下缸体是汽车发动机中的关键部件之一

采用压铸成形具有相当大的难度。针对某汽车发动机铝合金下缸体零件的结构特点

成功开发了下缸体的压铸件。通过对压铸工艺方案、模具冷却、镶件预热温度、压射工艺参数优化等方面的技术攻关

降低了下缸体压铸件内部气孔、缩松、镶件分离等缺陷出现的几率

提高了铸件品质及产品合格率。

Abstract

Al alloy cylinder bottom-end is one of the key parts for the vehicle engines

and it is difficult to produce by die casting due to its complicated structure.Al alloy cylinder bottom-end was produced successfully by die casting base on considering its structural characteristics.The defects such as gas pore

shrinkage porosity and insert-separation are successfully eliminated by some measures including optimization of venting and shot parameters

die cooling and pre-heated treatment of inserts

improving the quality and decreasing rejected rate.
