Abstract

A dual cavity hydraulic tire press utilizes a single long stroke piston-cylinder assembly vertically positioned substantially in line with the center of gravity of the vertically movable upper mold sections, the latter being supported on the underside of the outer ends of a shallow V-shaped beam which is mounted for vertical movement on a readily removable column or post. In the closed position of the press the top mold cavities are locked to the base of the press by rotatable bayonet locks. Four short stroke hydraulic clamp piston-cylinder assemblies are positioned beneath each bottom mold section to achieve clamping pressure during cure and are provided with extended coolant passages between the clamp actuating fluid and the heat of the mold cavity to preclude degradation of the fluid employed.
