Abstract:
1. A mold for casting a vehicle wheel comprising: a base segment; a top segment movable between a retracted position and an extended position; first and second side segments movable between retracted positions and extended positions; said base, top and side segments cooperating when said top and side segments are in said extended positions to define a mold cavity, said first and second side segments further cooperating when in said extended position to define a gate cavity; said gate cavity being adapted to receive molten metal and communicating with said mold cavity; and a pair of matrices of fingers with each of said matrices mounted within the portion of said gate cavity formed in one of said side segments, said matrices of fingers extending in a general orthogonal direction with respect to the flow direction of molten metal and co-operating with one another when said side segments are extended to restrain the flow of molten metal through said sprue.
