ABSTRACT:
A molding tool is provided that has a cavity half and a core half for molding a workpiece. The molding tool has a male trimpiece that is attached to the cavity half of the molding tool via a plurality of securing devices for removal of the male trimpiece when worn. A female trimpiece is attached to the core half of the molding tool via a plurality of securing devices for removal of the female trimpiece when worn. An adjustable stop plate is also provided that is attached to the core half of the molding tool via a plurality of securing devices. The stop plate is disposed around, and is adjacent to, the female trimpiece. The stop plate is vertically adjustable to provide for varying thickness of the workpiece. A trimline retention reservoir is also disposed in the core half of the molding tool between the female trimpiece and the stop plate for receiving the male trimpiece when the molding tool is in the closed position. The thicknesses of each trimpiece can be varied so as to change the size of the workpiece. Moreover, the male trimpiece can be notched so that the workpiece can be made with a protruding flange.
