Device for preheating at least one mold

The invention relates to a device for preheating at least one mold for a tire heating press, which has a coupling for applying a heating medium to the mold. The mold to be heated is enclosed by a receiving container (19), which is secured within a framework and creates the coupling for the heating medium. The device helps to provide effective preheating of the mold by an insulating shroud (2), which is positioned over the receiving container (19) during the preheating process and reduces heat dissipation into the surroundings.

Method for vulcanising a tyre blank

A method having the following steps is proposed: a) placing a green tire (20) to be vulcanized in a vulcanization mold, b) evaluating the temperature progression from the temperature sensor disposed in the cavity of the inner heater, wherein the energy input is adjusted both via the duration of the idle time and via the starting temperature, c) calculating an adjustment in the duration for the steam phase (24) of the inner heater when the idle time varies from a defined threshold, d) introducing steam into the inner heater of the vulcanization press and performing the steam phase (24, 25) for the calculated duration, wherein the adjustment of the duration for the steam phase (24, 25) is intended to ensure an optimal input of thermal energy for the vulcanization of the green tire (20), e) measuring the actual temperature progression with the temperature sensor (16) in the inner heater, f) comparing the actual temperature progression (27) with a target temperature progression (26) for a particular vehicle tire type, g) adjusting the duration for the flexible heating phase (28) of the inner heater, wherein the adjustment of the duration for the heating phase (28, 29) is intended to ensure an optimal input of thermal energy for the vulcanization of the green tire (20), h) completing the tire vulcanization.

Tire vulcanizing apparatus

An apparatus for vulcanizing a tire comprises: a side mold segment provided with a face for shaping the outer surface of a tire sidewall portion, and an opposite face not serving for shaping; and a heater part for vulcanizing the raw tire. The heater part is disposed adjacently to the side mold segment to heat the raw tire abutting on the side-shaping-face from the side of the face not serving for shaping. The side mold segment is provided with a flow path through which a first fluid whose temperature is lower than the vulcanization temperature of the raw tire can flow to prevent over-vulcanization of the sidewall portion.

A waterless tire curing system for curing a tire in a mold includes a platen and a mold jacket configured to have at least one component of the mold coupled thereto. The platen and the mold jacket include an induction coil. An electric coil is provided that produces an electromagnetic field to induce an eddy current into the induction coil to produce a first heat energy. A bladder is disposed in an interior of the mold and a nitrogen supply system is included to provide a heated pressurized nitrogen gas for circulation through the bladder. The heat energy from the induction coil is transferred to the mold and the uncured tire. The heat energy from the heated pressurized nitrogen gas is transferred to the bladder and the uncured tire, wherein the heat energy transferred to the uncured tire is effective to cure the tire.

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.
