U型支架铸造工艺设计

Casting Process Design of U Type Bracket

针对U型支架铸件技术要求及结构进行分析,对砂芯、浇注系统、冒口、冷铁等铸造工艺进行了设计。设计中采用了隙缝式浇注方式,并利用ProCAST数值模拟软件对铸件进行充型过程和凝固过程模拟,确定了合理的浇注及补缩系统。最后经过生产验证,铸件内、外部质量达到技术指标的要求,获得了合格的铸件,证明了工艺方案的合理性。

According to the technical specification requirements and structure characteristic of U type bracket casting, the sand cores, gating system, riser, chill and other process methods were designed, and then the mold-filling process and solidification process of the casting were simulated by using ProCAST numerical simulation software. Based on the simulation results, the reasonable gating and feeding system was determined. Finally, the castings were produced in accordance with the determined process, and the qualified castings were obtained, which proved the rationality of the casting process planning.
