一种整体式齿轮箱铸造工艺及模具设计研究

Research on Casting Process and Die Design of an Integral Gearbox

针对一种整体式齿轮箱进行了铸造工艺设计、铸造CAE仿真及模具设计研究。通过合理地设计浇注系统、激冷冷铁和发热保温冒口等工艺措施,并采用预埋覆膜砂型芯、整体筋板抽活块等模具设计方案,成功开发了满足质量要求的整体式齿轮箱铸件。

In this paper,the casting process design,casting CAE simulation and die design research are carried out for a kind of integral gearbox.Through reasonable design of gating system,chill,heating and insulation riser and other technological measures,and adopting mold design schemes such as embedded coated sand core,integral rib plate pumping block,the integral gearbox casting meeting the quality requirements has been successfully developed.
