ABSTRACT:
A tire press has an upper mold fixedly attached to a top plate. A bottom mold is fixedly attached to a bottom plate. The tire press has a plurality of guide posts adapted to maintain proper alignment of the upper mold and the lower mold as the tire press opens and closes. A plurality of lock rods, which are independent of the guide posts, are positioned about the tire press. Each of the lock rods has a first end and a second end. The lock rods may have an adjustment mechanism positioned on the first end of the lock rods to adjust the various mold heights. Locking means are a part of the tire press, which are adapted to selectively engage the second end of the lock rods. Further, each of the lock rods has cylinder mechanism operatively connected to the locking means. The cylinder mechanism is adapted to force the locking means to the surface of the lock rods. The cylinder mechanism is a hydraulic cylinder having the piston disposed within the chamber. The piston has a release side and a squeeze side, such that when fluid is introduced on the squeeze side, a substantially equal amount of tension is placed on the lock rods to lock the tire press. When fluid is introduced on the release side, the locking means can be removed from the lock rods and the tire press can be opened.
