ABSTRACT:
An upstream runner component defines an upstream channel for flow of molding material. A downstream runner component defines a downstream channel for flow of molding material. A wedge seal is disposed in a converging gap defined surface of the upstream runner component and the downstream runner component. The wedge seal defines a seal channel connecting the upstream channel to the downstream channel. Pressure of molding material acting on an inside surface of the wedge seal defining the seal channel pushes the wedge seal into sealing contact with the surfaces of the upstream runner component and the downstream runner component defining the converging gap.
