Zusammenfassung:A casting tool for a piston may include a casting mold for forming a piston part from a casting melt and a casting head including a feeder for feeding the casting melt into the casting mold. The casting head may include a ring-shaped groove, and the groove may include an inner groove flank for forming the casting melt into a circumferential, ring-shaped sealing rib such that an inner rib flank of the sealing rib rests with a sealing effect against the inner groove flank when the casting melt solidifies in the groove. Additionally or alternatively, the casting head may include a ring-shaped collar, and the collar may include an outer collar flank for forming the casting melt to provide a circumferential, ring-shaped sealing groove such that an outer groove flank of the sealing groove rests with a sealing effect against the outer collar flank when the casting melt solidifies.
