摘要
以某种提升箱体为铸造工艺设计对象,通过对其结构功能性分析,为其设计了顶注式和底注式两种浇注系统,并使用ProCAST模拟软件对两种浇注系统进行数值模拟与对比分析后,选择了底注式浇注系统。针对底注式浇注系统进行了两次工艺优化,先后分别增设了发热保温冒口、出气孔和冷铁。经模拟分析证实优化措施有效,铸件的铸造缺陷出现的概率大大降低。
Taking a certain lifting box as the object of casting process design,through the analysis of its structure and function,two kinds of pouring systems,top and bottom gating systems,were designed for it.After numerical simulation and comparative analysis of the two kinds of pouring systems using ProCAST simulation software,the bottom gating system was selected.Two process optimizations were carried out for the bottom pouring system,and hot and insulating risers,vents and chills were added successively.The simulation analysis confrmed that the optimization measures were effective,and the probability of the casting defects was greatly reduced.
