在实验研究的基础上，提出消失模型真空吸引铸造法。在用铸铝进行浇注的条件下，对平板模型进行了充型实验，通过改变真空负压、浇注温度、内浇口面积观察充型情况，分析各因素对充型过程影响，获得了在各种条件下金属液充型的等时曲线，找出了其充型形态规律
Based on the experimental research, the vacuum-lost casting method of vanishing model is proposed. Under the conditions of casting with cast aluminum, filling experiments were carried out on the flat plate model. The filling conditions were observed by changing the vacuum negative pressure, the pouring temperature and the inner gate area. The influence of various factors on the filling process was analyzed. Under the conditions of liquid metal filling isochronal curve, to find out the shape of its filling patterns
