Abstract: A post-cure inflator wherein an upper rim is automatically exchanged. A locking shaft is mounted for rotation on a rotary frame, and an upper rim support is mounted for rotation on the locking shaft. An upper rim is removably supported on the upper rim support. Also a lower rim support is removably supported on the locking shaft, and a lower rim is removably supported on the lower rim support and cooperates with the upper rim to hold therebetween a vulcanized tire, into which high pressure air is blown to inflate and cool the tire. The upper rim support and the upper rim have cooperating tapered fitting portions, and the upper rim has an outer peripheral circumferential groove formed at an upper portion thereof. A latching member is mounted on the upper rim support for movement into and out of the outer peripheral circumferential groove of the upper rim.

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.
