摘要

针对重型卡车发动机缸盖壁厚不均这一结构特点

根据产品工艺要求与年产量

将低压铸造工艺改为压铸工艺

从材料成分、内浇口、压射比压等方面对其压铸工艺进行了改进与优化

确定了压铸工艺参数

基本消除了产品粘模、开裂、气孔等缺陷。经对生产的压铸件随机抽样进行平面气孔泄漏测试

产品合格率稳定在95%左右。

Abstract

According to the structure characteristics of uneven wall thickness、product requirements and annual output of cylinder head of heavy truck engine

die casting process instead of low-pressure casting process was adopted.The die casting process from the aspects of material composition、gate and injection pressure was improved and optimized

and the die casting process parameters were determined

finally the product defects including solder、crack and porosity were eliminated.Product qualified rate is approximately 95%steadily through testing plane hole leakage at random.
