某减速器箱体为批量较大的中型铝合金件。在充分考虑其结构及工艺性后,确定采用砂型铸造、冷芯盒组芯造型进行生产,并对其浇冒系统进行了设计。采用Any Casting软件对铸造工艺进行了模拟,预测了铸件缺陷位置,通过添加冷铁消除了缺陷。 A reducer box for large volume of medium-sized aluminum alloy pieces. After fully considering its structure and technology, it is determined that sand casting and cold box core shape are adopted for production, and the design of its pouring and pouring system is designed. Any Casting software was used to simulate the casting process, predict the location of defects in castings, and eliminate defects by adding chilled iron.
