基于左末端传动壳体的结构特点及技术要求,确定了消失模铸造生产的相关工艺参数。选用EPS模料并采用了无冒口工艺方案。最后对工艺方案进行凝固过程模拟分析,得到了较为客观、准确的结果,从而反映出针对该件采用消失模铸造方法的可行性。 Based on the structural characteristics and technical requirements of the left end transmission housing, the related process parameters of the lost foam casting are determined. EPS model selection and the use of non-riser process program. Finally, the process of simulation of the process of solidification process, obtained a more objective and accurate results, reflecting the piece for the feasibility of using the lost foam casting method.
