摘要
对某气缸盖在生产验证时出现的集中气孔缺陷进行了系统的原因分析,阐述了具体的工艺改进措施及效果,重点探讨了砂型(芯)排气对形成气孔缺陷的影响。
The cause's analysis of the concentrated blowhole defects in some cylinder head during production verification has been systematically carried out.The specific process improvement measures and effects have been described,and the impact of sand mold(core)exhaust on the formation of blowhole defects has been discussed.
