- 摘要:
- 根据不锈钢复杂泵体的结构特点设计浇注系统,选择了熔模铸造型壳与合金的热物性参数,对复杂泵体的蜡模注射成型过程与铸件凝固过程进行数值模拟分析和生产验证。结果表明,通过增加冷铁、优化冒口尺寸,选择最佳方案,缩短了产品试制周期,提高了产品合格率。According to the structural characteristics of the complex stainless steel pump, the gating system was designed, and the thermo-physical parameters of the investment casting shell and the alloy were selected. Numerical simulation and production verification of wax injection molding process and casting solidification process of complex pump were carried out. The results show that by increasing the chillers and optimizing the size of the risers, the best scheme is selected, which shortens the trial production period and improves the pass rate of the products.
