The die set comprises upper and lower die plates, with the slidable mounting arrangement comprising a pair of inwardly opening receiving grooves for slidably receiving the opposite edge portions of the lower die plate, and a coupling arrangement for operatively connecting the upper die plate and the actuator piston rod for vertical reciprocal movement together attendant to slidable positioning of the die set within the press frame.
