The
casting mechanism comprises a rack, a
portal frame, an execution
assembly, a material containing
assembly, a material removing
assembly and a cleaning box, the material removing assembly comprises a circular plate, a feeding port, a material shoveling piece, a baffle and a surrounding edge, the feeding port, the material shoveling piece and the baffle are arranged at the top of the circular plate, and the surrounding edge is installed on the outer side of the top of the circular plate; according to the material removing device, the material removing assembly is arranged and driven by the execution assembly, the distance between the material shoveling piece and the liquid level of molten
aluminum can be accurately adjusted, the
impurity removing requirements of different liquid level heights are met, the driving piece drives the circular plate to rotate, the material shoveling piece is driven by the baffle to
shovel oxide skin through the feeding opening, and the material shoveling piece is driven by the baffle to
shovel the
oxide skin through the baffle and the surrounding edge. The three material shoveling pieces distributed in a surrounding mode synchronously
shovel the
oxide skin through the feeding port, the included angle of the shoveling face
ranging from 15 degrees to 30 degrees is matched, the
impurity removing efficiency is greatly improved, it is guaranteed that the oxide skin is thoroughly removed, manual close-distance operation is not needed, and automatic oxide skin removing is achieved.
