Abstract: A casting mould for casting complex-shaped castings from a molten metal. The casting mould has a mould cavity forming the casting and a delivery system that delivers molten metal into the mould cavity. The delivery system includes a sprue, a runner connected to the sprue and a feeder system connected to the runner. The mould cavity is connected to the feeder system or the runner via connections. When seen in the flow direction of the molten metal flowing from the sprue into the runner during the casting operation, the runner has a branch directed away from the sprue along the feeder system and has a directed-back branch adjoining the directed-away branch and guided along the feeder system in the opposite direction to the directed-away branch. The feeder system is connected to both the directed-away branch and the directed-back branch via two or more gates distributed along the respective branch.

Abstract: The present invention relates to a casting mould for casting complex-shaped, large-volume castings from a molten metal, wherein the casting mould has a mould cavity forming the casting and a delivery system for delivery of the molten metal, which is to be cast into the casting, into the mould cavity, wherein the delivery system comprises a sprue, a runner connected to the sprue and a feeder system connected to the runner, and wherein the mould cavity is connected to the feeder system or the runner via connections, and the use of such a casting mould. The casting mould according to the invention makes it possible to reliably produce castings of a highly complex shape, even from alloys which can be difficult to cast using conventional methods and whose casting results can be of an unreliable quality.
