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.

In a plastic or die cast molding machine having opposed stationary and movable platens adapted to receive, mount and support a sectional plastic molding die having opposed stationary and movable guidably interconnected clamps plates comprising; opposed inwardly facing symmetrical quick change locator clamp assemblies mounted upon said platens; each clamp assembly including a body plate bearing against and secured to a platen; laterally spaced index pins mounted upon said body plate and projecting outwardly thereof; there being correspondingly spaced keyhole slots within the corresponding edges of said clamp plates adapted to cooperatively receive said pins for locating said clamp plates relative to and against said body plates respectively; longitudinally spaced opposed inward directed pairs of plate clamps adjustably and guidably mounted upon opposite sides of said body plate adapted to receive and retainingly engage opposite sides of a clamp plate; and rotatable screw means interconnecting each pair of clamps rotatable in one direction for simultaneously moving each pair of clamps inwardly to operatively and retainingly engage a clamp plate for securing said clamp plates to said platens respectively; and alternately rotatable in the opposite direction for moving each pair of clamps outwardly to disengage said clamp plates to facilitate removal of said sectional die and clamp plates from said platens.
