摘要：A die apparatus permits the formation of an internal recess in a molded part.The die apparatus includes first and second mold members which are movable betweenan open and closed position. A core pin assembly includes a first core pin element and asecond core pin element supported between the movable mold members for relativemovement therewith. A resiliently deformable element is positioned between the firstand second core pin elements. The resiliently deformable element is deformablyexpandable to form an external projection upon relative movement of the moldmembers to a closed position, and is elastically returnable upon the relative movementof the mold members to an open position.
