用铸型浸入金属液的方法来获得铸件,工艺简单可行。尺寸小(最大～40mm)而形状简单的铸件,可用多型腔一次铸成。图1为高速钢端面铣刀坯件的浸入法铸造。图1中:1——水冷结晶器(兼作上半型),2——金属液,3——陶瓷壳型,4——铸件,5——浇口。铸件凝固时上端冷却快,又有良好的底注,可确保铸件中金属组织致密。制造复杂的铸件有时不能使用水冷结晶器,因与铸件接触面小而高度大时收效不大。图2为浸注青铜衬套(壁厚7mm,高50mm)的示意。衬套4的酚醛树酯砂型,固定在吊架1上.砂型2采用了全截面注入 Casting immersed in liquid metal method to obtain castings, the process is simple and feasible. Small size (up to ~ 40mm) and a simple shape of the casting, the cavity can be cast once. Figure 1 shows a high-speed steel end milling cutter blank casting method. Figure 1: 1 - water-cooled mold (also known as the upper half), 2 - metal liquid, 3 - ceramic shell, 4 - casting, 5 - gate. Casting solidification of the upper end of the fast cooling, there are good endorsements, to ensure that the metal in the castings dense. Sometimes the manufacture of complex castings can not use water-cooled crystallizer, due to the small contact surface with the castings and large height ineffective. Figure 2 is immersed bronze bushing (wall thickness 7mm, height 50mm) of the schematic. The bushing 4 is of phenolic resin sand mold and is fixed on the hanger 1. The sand mold 2 adopts the full cross section injection
