Abstract (en)
[origin: US6460603B1] An apparatus for uphill low pressure casting of metals in split sand moulds and having a sprue in one of the two moulds, to which can be connected the casting tube of a melt container and which is connected to the lowest area of the mould cavity, and having a sealing plug integrated into the mould and which after the filling of the mould cavity can be brought into the closed position by means of an external drive engaging in the mould, including a seal which does impairing casting quality and moulding sand preparation. Between the sprue and the mould cavity is provided a casting channel connecting the sprue and the mould cavity. The sealing plug is constructed as a sand mould body and in a shaped-in guide of the mould is displaceable between an open position and a closed position, and seals a casting channel and a metallostatic pressure of the molten metal in the mould acts against the guide on the sealing plug.
