Abstract
A tire vulcanizing mold assembly includes an upper flange disposed on an outer peripheral portion of an upper mold of a tire vulcanizing mold or an upper flange disposed in the outer peripheral portion of a plate into which the upper mold is assembled, a lower flange disposed in an outer peripheral portion of a plate into which a lower mold is assembled so as to go up and down, and a lock ring which is rotatably assembled into one of the respective flanges and detachably engaged to the other flange, wherein one end portion of a pressurizing unit is detachably engaged to the plate, an output shaft is engaged onto the other end portion of the pressurizing unit so as to abut against the lower mold through the plate portion, and when the tire vulcanizing mold is closed so that the respective flange portions are coupled to each other by the lock ring, a mold opening force due to the inner pressure of the tire vulcanizing mold is prevented.
