摘要
对于内腔结构复杂的大型铸件,气孔类缺陷影响到铸件的整体质量,所以在生产过程中砂芯排气是否畅通至关重要。提出了一种采用金属软管的砂芯排气新工艺,制芯时预埋金属软管,研箱时从芯头处再连接金属软管引至铸型外,从而形成了一条完整的排气通道,有效解决了砂芯排气问题。
A new type of sand core exhaust technology with metal hose has been presented in the text.The metal hose has been pre-embedded in the sand core and another metal hose has been connected from the core head to the outside of the mold in the assembling process. Thus in this way, a complete exhaust passage has been formed. The exhaust problem of the sand core has been solved effectively.
