摘要
针对城轨齿轮下箱体铸件,利用UG三维软件辅助计算确定铸件关键模数Ms;采用均衡凝固技术,设计浇冒系统;基于Procast数值模拟软件,进行充型及凝固过程数值模拟,有效地预测了在凝固过程中出现的缩松缩孔问题的位置,对铸造工艺方案进行优化处理,缩短新产品试制周期,降低生产成本.
Abstract
For the casting of the lower box of the urban rail gear,UG 3D software is used to calculate and determine the key module Ms of the casting;Adopt proportional solidification technology to design pouring and pouring system;Based on Procast numerical simula-tion software,the mold filling and solidification process numerical simulation is carried out,the location of shrinkage porosity and shrink-age cavity problems in the solidification process is effectively predicted,and the casting process plan is optimized to shorten the trial production cycle of new products and reduce production costs.
