Abstract
An apparatus for vulcanizing a vehicle tire comprises upper and lower platens supporting mold shell sections which when mounted one on the other form a mold enclosing a mold cavity. The upper platen is moved first vertically and then laterally with respect to the lower platen by a bull gear crank. A vulcanizing bladder is stretched by a piston rod of a fluid-dynamic piston-cylinder assembly through the opening of a vehicle tire casing disposed in the mold cavity to facilitate loading of the casing in the mold cavity. The apparatus is also provided with a second fluid actuated piston-cylinder assembly to move the upper platen while maintaining the bladder standing sufficiently, in relation to the lower plane of the mold, in such a way as to adapt the press even for unloading tires having dimensions larger than those of the usual tires for which the apparatus was originally built.
