ABSTRACT:
A vertical tire press has a lower mold fixed to a lower platen mounted on a base, and an upper mold facing the lower mold and fixed to an upper platen mounted on a top slide. The top slide is moved vertically by a crank mechanism, thereby closing together or opening apart the upper and lower molds. The lower or upper platen has a cylinder structure so as to squeeze together the upper and lower molds. This vertical tire press basically employs a crank mechanism, but is free from disadvantages peculiar to a tilt-back type tire press. The vertical tire press provides good economic performance as well as advantages of an oil-hydraulic type tire press, i.e. uniform application of a squeezing force and easy adjustment of the squeezing force, without using an oil-hydraulic cylinder.
