铝合金复杂管路的石膏型预埋铸造工艺

Plaster Mold Embedded Casting Process for Complex Pipeline Aluminum Alloy

针对内部存在复杂管路的铝合金铸件,采用常规预埋型芯方法,铸件中管路无法满足要求。通过提前在蜡模内预埋钢管,将钢管两端加长固定等方法,成功铸出薄壁、复杂管路铸件,从而为带有复杂管路铝合金薄壁铸件的石膏型铸造问题提供了一种解决办法。

For aluminum alloy castings with complex internal pipelines,the piping in the casting cannot meet the requirements by using the conventional pre-buried core method.By pre-buried the steel pipe in the wax pattern in advance and fixing the steel pipe by lengthening both ends,thin-walled and complicated piping castings were successfully casted,providing a solution to the problem of plaster casting of thin-walled aluminum alloy castings with complicated piping.
