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.
