硅溶胶铸造在精密铸造领域中是一种被广泛运用的精密铸造方式,这种精密铸造方式有效降低了成本,提高了精密铸造企业的竞争力。浇注成型是硅溶胶铸造中一个最重要的步骤,那么硅溶胶铸造有哪些常见的浇注方法呢?
Silica sol casting is a widely used precision casting method in the field of precision casting. This precision casting method effectively reduces the cost and improves the competitiveness of precision casting enterprises. Casting molding is one of the most important steps in silica sol casting. What are the common casting methods of silica sol casting?
1. 压力下结晶,将型壳放在压力罐内进行浇注,结束后,立即封闭压力罐,向罐内通入高压空气或惰性气体,使铸件在压力下凝固,以增大铸件保定平面设计培训  防撞墙模具 防撞墙模具 防撞护栏模具 大棚遮阳网 遮阴网的致密度。
1. Crystallize under pressure. Place the mold shell in the pressure tank for pouring. After that, immediately close the pressure tank and inject high-pressure air or inert gas into the tank to solidify the casting under pressure, so as to increase the density of the casting.
2.真空吸气浇注,将型壳放在真空浇注箱中,通过型壳中的微小孔隙吸走型腔中的气体,使液态金属能更好地充填型腔,复制型腔的形状,提高铸件精度,防止气孔、浇不足的缺陷。这种方法国外较常见。
2. Vacuum suction pouring: put the mold shell in the vacuum pouring box and suck out the gas in the mold cavity through the small pores in the mold shell, so that the liquid metal can better fill the mold cavity, copy the shape of the mold cavity, improve the casting accuracy and prevent the defects of pores and insufficient pouring. This method is more common abroad.
