Abstract
The present invention provides a clamp assembly for use in combination with a vulcanization press for curing tires wherein the press includes a frame for supporting upper and lower platens carrying upper and lower cooperating mold halves. The platens are movable toward and away from each other such that the mold halves may be moved toward a closed mating position and an open tire receiving position. The clamp assemblies of the present invention hold the mold halves onto their respective platens and include an elongated clamp body which is mounted to the press frame adjacent to a platen and a sliding wedge member which is guided for movement toward and away from the platen along the clamp body. The mold halves are each provided with a wedge-shaped clamp ring and pneumatic cylinders are provided for moving the sliding wedge member forward to engage the clamp rings and thereby hold the mold halves in place on the platens.
