A ring carrier, for use in a piston casting die, is an annular-shaped member (1) having a channel on an outer surface area. The piston casting die includes projections (6,5) for engaging the channel and supporting the ring carrier (1) within the piston casting die. At least one of the projections (6) is fixed and at least one other of the projections (5) is movable into and out of the piston casting die. The movable projection includes a driving member (8) for urging the movable projection into engagement with the channel for supporting the ring carrier (1) at a predetermined position within the piston casting die. <IMAGE> |
