In a plastic or die cast molding machine having opposed stationary and movable platens adapted to receive, mount and support a sectional plastic or die cast molding die having stationary and movable clamp plates, opposed quick change locator clamp assemblies mounted upon the platens, each clamp assembly including a body plate secured to a platen. Laterally spaced index pins project from the body plate for receiving corresponding spaced locator slots in the clamp plates. Longitudinally spaced opposed pairs of plate clamps are adjustably and guidably mounted upon opposite sides of the body plate adapted to receive and retainingly engage opposite sides of a clamp plate. A manually rotatable screw having right and left hand threads adjacent it opposite ends threadedly engages the corresponding opposed plate clamps for simultaneously moving each pair of plate clamps inwardly to retain a clamp plate or in the opposite direction to disengage the clamp plates and facilitate removal of the sectional die from the platens.
