  • Patent number: 11192318
    Abstract: In a tire vulcanization device, a vertical position of a container ring is locked at a closed position by a lock mechanism. A pressurizing mechanism is operated so as to decrease a vertical gap between an upper plate and a lower plate. The lower plate is moved upward so that a segment is moved toward a center mechanism by a container ring and sector molds are assembled in an annular shape. A state where a predetermined vertical gap is formed between the container ring and a bolster plate by a vertical connection mechanism is created. An upper side mold disposed on a lower surface of the upper plate is closed by being pressed against an upper surface of each of the sector molds while maintaining a state where the sector molds are assembled in an annular shape.
