介绍了缸体群架铸件结构、模具结构及批量生产中产生泄漏的原因。通过采用单点独立水冷却的方式，有效地控制模具局部温度，避免在铸件热节处由于型芯和型腔局部过热造成铸件产生缩孔、缩松等缺陷。同时还介绍了对于?5 mm以下型芯的水冷方法，解决了压铸模设计难题。

Casting construction

mould structrue and origination of leakage of engine block frame were introduced

and sinle point water cooling system was adopted to control partial die temperature in order to avoid shrinkage hole

shrinkage porosities at hot spot resulting from part of overheating of core and cavity. In addition

the method of water cooling for the core with less than ?5 mm was described to solve a problem in die casting die design.
