A pair of frame members are connected in laterally spaced, parallel relation; and, when mounted on a molding machine, the frames extend perpendicularly to the centerline of the machine's mandrels. A major center portion of each frame is excised to provide a pair of aligned window-like openings surrounded by perimetric portions of the frames. Actuators are secured between the spaced frame members and have extensible piston rods attached to mold segments for advancing and retracting the same within the openings. Movement of a machine platen occurs along an axis which penetrates the openings; and, piston rod movement is generally normal to movement of the platen.
