To investigate the relationship between interfacial heat transfer coefficient and evolution of interfacial contact during vacuum-assisted high pressure die casting, a combined approach of neural network and numerical simulation was adopted to obtain interfacial heat transfer coefficient and high-precision temperature field. By calculating the actual contact area between casting and mold during solidification, the evolution process of interfacial contact in vacuum-assisted high pressure die casting was studied. It is found that the variation trend of interfacial heat transfer coefficient is consistent with that of the actual contact area. Based on the variation of the actual contact area, the evolution of interfacial contact is divided into five stages. At different stages, pressure retards the decrease in the actual contact area by different actions and enhances the interfacial heat transfer coefficient. At the third stage (C), pressure has a direct impact on the actual contact area, resulting in a reduction of 8.5%-15.0%; at the fourth stage (D), the actual contact area is reduced by 49%.

为了探究真空辅助高压铸造过程中界面换热系数与界面接触演变的关系，通过神经网络和数值模拟相结合的方式获得了界面换热系数和高精度温度场。通过计算凝固过程中铸件-模具的实际接触面积，研究了真空辅助高压铸造界面接触的演变过程。发现界面换热系数的变化趋势与实际接触面积的变化趋势一致。根据实际接触面积的变化情况，将界面接触的演变划分为5个阶段。在不同阶段，压力以不同作用延缓实际接触面积的减小，提高界面换热系数。在阶段C（第3个阶段），压力直接影响实际接触面积，实际接触面积降幅为8.5%~15.0%；在阶段D（第4个阶段），实际接触面积降幅达49%。
