A runner plate for an injection molding system comprises a plate typically having a plurality of corners, and typically apertures extending through the plate for receiving leader pins of the molding system for support of the plate in the molding system. Also at least a pair of outrigger supports may be provided, the outrigger supports being carried by the plate, each at a different position on the plate, and typically extending diagonally outwardly relative to adjacent plate edges. Also the outrigger support may carry rollers which are positioned to engage tie bars of the mold press for rolling contact therewith and support of the system. A mold which contains the runner plate may, by this invention, have leader pins that are longer than corresponding pins of the prior art, extending through the entire mold from, typically, the mold core on one side of the mold to a mold core on the other side of the mold, in the case of double action molds, with the leader pins being long enough to extend through the entire mold even in the open position, for added support. In such a circumstance, the outrigger supports may be dispensed with.
