Rigid core mold removal device and tire manufacturing method
A method for manufacturing a tire T comprises a step for forming a green tire on the outside of a rigid core mold 2, a step for vulcanization-molding and obtaining a tire-accompanying rigid core mold G, a step for setting, at an assembly station P3, a core 5 taken out from the tire-accompanied rigid core mold G, and a removal and assembly step for removing one core segment 3 from the tire T by moving in inwardly in the tire radial direction from the tire-accompanying rigid core mold G and mounting it on the core 5 set at the assembly station. The removal and assembly step is performed for every core segment in the tire, whereby a rigid core mold 2 is assembled at the assembly station P3, while removing the rigid core mold 2 from the tire T.
TIRE CURING PRESS
Disclosed is a tire curing press. The tire curing press includes: a curing bladder; a lower clamping assembly for clamping a lower flange of the curing bladder; and an upper clamping assembly for clamping an upper flange of the curing bladder. An upper end of a center rod is fixedly connected to the upper clamping assembly, and the center rod is capable of a lifting motion in a longitudinal direction relative to the lower clamping assembly. The tire curing press further includes a heating component, a stirring component, and a rotary driving member. The tire curing press further includes a rotating cylinder rotatably arranged to pass through a bore of a ring seat, where one end of the rotating cylinder projects from one side of the ring seat and is connected to the stirring component, the other end of the rotating cylinder projects from the other side of the ring seat and has a stator assembly fixed to the periphery thereof. The center rod extends through the interior of the rotating cylinder. In the tire curing press, the rotating cylinder encompasses the center rod, such that a high-temperature high-pressure medium can be isolated in the rotating cylinder, thereby reducing or even eliminating the influence of the high-temperature high-pressure medium on the rotary driving member.
