ABSTRACT:
A mold changing apparatus for use in a tire vulcanizer includes a mold stations having tire molds disposed in a row, a movable mold open-close manipulator, and a mold preparing station provided at a proper position in the row of tire molds for centering and preheating a tire mold. A mold that has been centered and preheated completely in the mold preparing station is automatically received by the mold open-close manipulator, and it is then automatically transferred to and installed in the mold station where vulcanization is executed. A mold which is to be removed is automatically received from the mold station by the manipulator, and it is automatically transferred to the mold preparing station and separated from the manipulator. Subsequently, the manipulator automatically receives a new mold which has already been heated. Thus, a fully-automatic mold change is realized.
