It was introduced that formerly,since used hot-box core process to produce water jacket core,production efficiency was low,core making cycle was long,tools wear-off relatively bigger,gas evolution was bigger,and evolution rate was slower.A detailed description was given to using cold box process to produce water jacket core of cylinder block and tools design.Production confirmation showed:(1)In the inner cavity of the cylinder block casting which was made by using cold-box core,the sand lump were mostly loose,and easy to be cleaned.(2)The core making efficiency of the cold-box process was elevated by 60％compared with former hot core process.(3)The core-making cost of cold box process was reduced about 10％compared with formerly used hot box process.
