ABSTRACT:
A tire curing press (20) according to the concepts of the present invention includes a pair of spaced mold cavities (MC), base assemblies (22, 23) for supporting lower mold sections (L) in the mold cavities, a cross beam assembly (100) for supporting upper mold sections (U) in the mold cavities, a center post assembly (201) substantially aligned between the centerline of the mold cavities, and a lift mechanism (215) positioned interiorly of the center post assembly for supporting and vertically moving the cross beam assembly to open and close the press. A roller guide assembly (230) is provided for stabilizing and effecting precision vertical movement of the cross beam assembly relative to the center post assembly, while a safety stop mechanism (275) precludes uncontrolled descent of the cross beam assembly from the press open position. A mold locking and clamping assembly (120) locks the mold section (L, U) and applies squeeze forces thereto when the press is closed for curing a tire.
