Abstract:
Apparatus for uphill low pressure casting of metals, in a split sand mould comprising:a sprue in the split sand mould, a casting tube connected to a melt container which is connectable to the sprue and which is connected with a lowest area of a mould cavity, a sealing plug integrated into the split sand mould and being movable by an external drive, while engaging the split sand mold from an open position into a closed position following filling of the mould cavity with melt; and wherein between the sprue and the mould cavity is provided a casting channel linking the mould cavity to the sprue with a direction of flow of melt in the sprue being at an angle with a direction of flow of melt in the casting channel, the sealing plug is constructed as a sand mould body and is displaceable in a shaped guide of the split sand mould between the open position and the closed position sealing the casting channel and metallostatic pressure of the melt in the split sand mould acts perpendicular to the guide and on the sealing plug.
