【摘要】：针对使用常规铸造工艺制造的新能源汽车电机壳出现缩松缩孔、气密性合格率低的问题,应用数值模拟技术对电机壳的挤压铸造工艺进行研究。通过对铸造充型、凝固过程进行模拟仿真,验证工艺设计的合理性,并结合单一变量法研究浇注温度、模具温度、比压等工艺参数对缩松缩孔的影响。最终确定最佳工艺参数为浇注温度680℃,模具温度280℃,比压110 MPa、压射速度0.1 m/s、保压30 s。在此参数下结合局部加压装置可以消除铸件的缩松缩孔,得到的铸件性能优良,气密性合格率达到88%。
[Abstract]:In order to solve the problem of shrinkage hole and low qualified rate of air tightness in the new energy motor shell manufactured by conventional casting technology, the squeeze casting process of motor shell was studied by numerical simulation technology. Through the simulation of casting filling and solidification process, the rationality of the process design is verified, and the effects of pouring temperature, mold temperature and specific pressure on shrinkage are studied with a single variable method. The optimum technological parameters are as follows: pouring temperature 680 鈩，
