6M40压缩机机身铸件的组芯造型

Use Cores-Built-up Mould to Cast 6M4O Model Compressor Body

在分析比较了大中型铸件几种造型工艺方法后，对 ６Ｍ４０压缩机机身铸件采用组芯造型、组合砂箱、地面浇注的的工艺方案，较好地解决了生产制造过程中的难点，既减轻了工人的劳动强度，又提高了操作者的工作安全性。

After comparing several moulding methods used for large and medium castings, it was decided to adopt cores--built-up mould,split moulding boxes and pouring on the floor to produce the body casting of 6M40 model compressor.
