ABSTRACT:
In a mold clamping device for clamping a mold to, and unclamping the mold from, a mold mounting member of a tire vulcanizing machine, a locking member has a neck section projectingly installed on the mounting surface of a mold. A guide hole of the mold mounting member, in which the locking member is inserted, has a larger-diameter section in a portion corresponding to the neck section. A chuck member has an expansion section which is slidably inserted in the guide hole, and expands in the larger-diameter section, engaging the neck section in the guide hole. A chuck withdrawing device withdraws the chuck member into the guide hole.
