摘　　要：针对机床滑枕体积大、结构复杂,铸造加工中膨胀难以控制,易出现缩松、缩孔缺陷的问题,在对原滑枕铸造工艺及实际生产中出现缺陷分析的基础上,使用Pro CAST模拟软件对铸件凝固过程进行数值模拟。根据模拟结果对铸造工艺从浇注系统、冒口设计、冷铁布置等方面进行优化。最终克服铸件缩松、缩孔缺陷的出现,得到滑枕铸件铸造工艺的最佳方案。Aimed at the shrinkage porosity defect problems in slippery pillow of machine tool due to huge volume,complex structure and difficult-controlled inflation, the solidification process of the slippery pillow castings was simulated by software Pro CAST on the basis of analysis on the casting process and actual defects. According to the results of simulation, the casting process was optimized from pouring system, riser design, cold iron arrangement to overcome the emergence of the casting shrinkage porosity defect, the best scheme of the slippery pillow castings was obtained.
