金属型铝合金铸件浸沉浇注可以提高铸件质量,使金属材料利用率提高到80～90％,生产率提高1～2倍。目前,苏联已研制成功一种机械化的浸沉浇注装置(如附图所示),效果很好。浸沉浇注时,将金属型1浸入金属液2,到一定深度后停住不动。金属液从底浇口和侧浇口浸入型腔,待铸件完全凝固后取出金属型。浇口面积和位置甚为重要,选择适宜则可以使铸件密实和无缩 Immersion casting metal alloy castings can improve casting quality, the utilization of metal materials increased to 80 to 90%, productivity increased by 1 to 2 times. At present, the Soviet Union has successfully developed a mechanized immersion pouring device (as shown in the accompanying drawings), and the effect is very good. Immersion pouring pouring, the metal type 1 immersed in the liquid metal 2, to a certain depth stopped. The molten metal is dipped into the cavity from the bottom gate and the side gate, and the metal is removed after the casting is completely solidified. Gate area and location is very important, the choice can make the casting dense and no shrinkage
