摘要:
分析了机座零件的结构特点及技术要求,利用双砂芯设计方案解决了复杂结构零件的铸造难题,通过MAGMAsoft软件对铸造工艺、充型、凝固过程进行模拟和分析,发现选择的铸造工艺方案在整个浇注过程金属液面比较平稳,没有紊流发生,内浇口在充型过程中始终处于充满的状态。同时,根据铸件缩孔、缩松等缺陷及热节的位置,提出了进一步优化方案为:上表面增加四个发热冒口或增加一个溢流冒口、底面设置覆砂冷铁以加快冷却速度。

Abstract: The structural characteristics and technical requirements of the machine base parts were analyzed; double sand core design scheme was used to solve the problems in casting complex structure parts. The casting, mold filling and solidification process were simulated and analyzed by MAGMAsoft software; it was found that the selected casting process could offer relatively stable metal liquid with no turbulence, and the gate was always kept in full state in the filling process. Meanwhile, a further optimization plan was developed according to the casting shrinkage, micro- hole and thermal section positions, which is increasing four exothermic risers or adding an overflow riser on the top surface, and setting chills on the bottom surface to speed up the cooling speed.
