Description of the Related Art In a vulcanization molding process which is close to the final stage of pneumatic tire (hereinafter referred to as "tire") production, it is necessary to cope with frequent size switching or type switching that is common in a preceding molding process. In almost all cases, it is necessary to replace a used old mold for vulcanization of a tire which has been mounted on a vulcanizer with a new mold in accordance with the switching of the molding size or the type of molding.

Even if the used old mold attached to the vulcanizing machine is replaced with a new mold for the next use, handling and operation are not easy. This also applies to the case where the mold is a two-piece mold, but the case of a split mold having a more complicated structure than the combined mold is more serious. This is because the split mold has a tread portion forming mold element divided into a large number in the circumferential direction, and a segment connected to each element and moving each element in and out in the radial direction.

Which discloses an upper and lower mold exchanging cart in a tire vulcanizer. The slide carriage is configured to be slidable toward the vulcanizer, and the swivel base has a mounting portion for two sets of mold assemblies. The slide carriage with the mold is mounted on a rail on the swivel base and vulcanized. It reciprocates on a connection rail with a rail in the machine.

As a third situation, the height of the lower mold supporting surface of each of the vulcanizers 1 to 5 (which greatly exceeds 5 in general) from the floor surface FL is not uniform.

成型用金型移載の場合に問題となる。Therefore, first, when the upper and lower mold exchanging device disclosed in the above publication is applied to a tire vulcanizing line, the exchanging device avoids the waiting unvulcanized tire and its mounting table, and vulcanizes. The vehicle must be driven in a forward position far from the machine. At that time, the span of the unsupported portion in the composite connection body is extremely long, and the unsupported portion cannot withstand a large number of runs of the sub-carriage on which the heavy metal mold is placed, no matter how reinforced. . In addition, this exchange device has insufficient positioning of the mold on the base, which is a problem particularly in the case of transferring a mold for tire vulcanization molding, where precise positioning is a decisive factor of high quality.

る。[0012] Next, the upper and lower mold exchanging trucks disclosed in the above publication No. 2 include a vulcanizer and a vulcanizing tire receiving space which is more than a vulcanizing tire receiving space. Fit the line. However, when the mold is replaced, a turning operation of the mounting portion of the mold assembly is required, so that improvement is required in that the replacement efficiency is low. Further, it is necessary to provide a rail for moving the slide carriage back and forth in the vulcanizer, and there is a drawback in that the vulcanizer needs to be largely remodeled. Further, the positioning means is for positioning the slide carriage with respect to the vulcanizer, and is not necessarily for positioning the mold with respect to the vulcanizer.

する。Finally, the mold exchanging device disclosed in the above publication No. 3 can move in a narrow passage, can use the existing vulcanizing machine without modifying the vulcanizing machine, and This is an excellent mold exchanging device in that mold exchanging can be performed smoothly. The automatic carrier on which this device is mounted also has an advantage that it can travel freely on the floor surface by, for example, an electromagnetic induction system by setting a destination in a railless self-propelled system. However, this type of mold changing device should be improved in that it is difficult to accurately position the mold changing device with respect to the vulcanizer, and that the structure of the device is complicated and expensive. Further, it is necessary to consider a method of supplying electric power required for transferring a heavy die.

That is, each of the proposed mold changing apparatuses has a problem in quickly changing a large number of molds within a short time.
