Patent ID: 7985359

Claim:
A tire vulcanizing apparatus comprising: a mold for removably accommodating a raw tire; a medium path, connected to an internal space of the raw tire accommodated in the mold, for passing a heating and pressurizing medium of a gas or air for vulcanizing and molding the raw tire; a pressure sensor, provided in the medium path, for measuring a pressure of the heating and pressurizing medium; a pressure control valve, provided in the medium path, for controlling the pressure of the heating and pressurizing medium passing through the medium path on the basis of a signal from the pressure sensor; a temperature sensor, provided in the medium path, for measuring a temperature of the heating and pressurizing medium; and a heating unit, provided in the medium path, for controlling the temperature of the heating and pressurizing medium passing through the medium path on the basis of a signal from the temperature sensor, wherein the pressure control valve controls the pressure of the heating and pressurizing medium passing through the medium path on the basis of a signal from the pressure sensor and not on the basis of a signal from the temperature sensor, and wherein the heating unit controls the temperature of the heating and pressurizing medium passing through the medium path on the basis of a signal from the temperature sensor and not on the basis of a signal from the pressure sensor, whereby the pressure and temperature of the heating and pressurizing medium supplied from the medium path to the internal space of the raw tire are respectively independently controlled without mutual relationship.
