Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire die transfer device for a tire die transport device applied to a tire vulcanizing facility. 2. Description of the Related Art The present applicant has already proposed a tire mold transporting apparatus for carrying in and out a heavy tire mold (see Japanese Patent Application No. 6-285237). The tire mold transport device includes a vulcanization station for arranging a plurality of sets of tire molds for vulcanization, opening the tire mold, removing a vulcanized tire, and inserting an unvulcanized tire to be vulcanized. A mold transport device that reciprocates between a mold opening / closing station that closes the tire mold after shaping, and a first track laid along the vulcanizing station and the mold opening / closing station, and a mold opening / closing station. And a bogie with a driving bogie that moves along a first track between a first position provided at a first position and a second position set at a plurality of locations in front of the vulcanizing station. A second track laid in an orthogonal direction, and a third track laid in a direction orthogonal to the first track at third positions set at a plurality of locations of the vulcanizing station;
A mold transfer device, wherein when one of the third tracks is connected to the second track on the drive-equipped trolley, the second track and the third track on which the mold transfer device is mounted are connected. It moves along the track and transfers the tire mold. [0003] In a vulcanizing facility to which the above-mentioned mold conveying device is applied, a vulcanizing station for arranging a plurality of sets of tire dies for vulcanization, and vulcanizing by opening the tire dies.

As described above, the tire mold transfer device of the present invention uses an electric motor as a drive source, and thus is necessary when the carrier is moved by, for example, operating a pusher by a hydraulic cylinder. It is not necessary to mount the fluid pressure unit on the tire mold transporting cart. In addition to this, equipment such as piping is not required, so that the tire die transfer device can be made compact and the fear of liquid leakage can be eliminated. Further, by rotating the electric motor forward and backward, that is, by one driving source, the tire mold assembly is moved in a transfer direction (loading direction and unloading direction) orthogonal to the running direction of the tire mold transporting cart. So you can
The number of parts can be reduced and the cost can be reduced. In addition, since the rack gear and the pionin gear are used for driving, maintenance can be made unnecessary and the necessity of replacing parts can be eliminated.
