Abstract
A modification to a multiple cavity tire press places a plurality of hydraulic cylinders beneath the lower mold half and heat platen of each mold in the press. The size of the side links of the press is adjusted so that in normal operation, the side links only bring the upper and lower mold halves into close registration and hydraulic pressure applied to the lower mold halves through the plurality of hydraulic cylinders gives the squeeze to the press halves, as well as eliminating or minimizing the malocclusion of the mold halves known in the prior art due to deflection of the respected upper and lower portions of the mold by application of mechanical squeeze.
