Abstract
The apparatus includes a wheel mold that has a top segment having a plurality of openings formed therethrough. Movable cores are carried in the top segment openings. A mechanism is mounted on the top segment to alternately extend the cores into the mold cavity and retract the cores into the openings. To form a wheel, the movable cores are extended and molten metal is introduced into the mold cavity. The movable cores form recesses in the resulting wheel casting. After casting has cooled sufficiently, the movable cores are retracted from the recesses allowing the top segment to be withdrawn from the wheel casting. The casting is then removed from the mold.
