ABSTRACT:
The invention makes it possible to manufacture high-quality cast parts in a productive manner in that a casting mould with a filling opening pointing in the direction of gravity is provided during the casting of molten metal. The casting mould with the filling opening is coupled to a melt container containing the molten metal, and the molten metal is conveyed from the melt container into the casting mould counter to the direction of gravity. The casting mould is sealed directly after filling with molten metal using a locking means which is at least temporarily connected to the casting mould in a fixed manner, in that the casting mould is decoupled from the melt container directly after closure of the casting mould and in that the casting mould is rotated about a horizontal axis of rotation, wherein the casting mould remains in a sealed position with respect to the locking means.
