V型干式缸套柴油机气缸体铸造工艺开发

Casting technique for V type dry cylinder block of diesel engine

介绍了一种V型干式缸套柴油机气缸体的工艺开发要点,对制芯及组芯工艺流程做了重点介绍。本工艺采用整体组芯、整体下芯的方式,可以稳定产出合格的气缸体铸件毛坯,铸件尺寸精度及尺寸一致性良好。

The cylinder block is an important part of the engine,especially the cylinder block of V diesel engine,technical requirements more stringent,process more difficult.This paper introduces the process development of a V type dry cylinder diesel engine cylinder block,and details the core making and core assembly processes.The vertical core assembly and vertical pouring technique is used in the process.This process can be used to produce qualifi ed casting cylinder block.And the casting dimension possesses high precision and good consistency.
