2. Description of the Related Art In recent years, in order to manufacture a high-performance pneumatic tire with high efficiency and low cost, a rubberized cord is knitted around a substantially doughnut-shaped inner mold for tire production, which is made of a rigid body. A belt is formed by spirally wrapping a rubberized cord radially outside the rubberized cord layer (carcass layer) to form a belt layer, and a belt-shaped raw rubber (tread rubber) is wound around the carcass and the belt layer to produce a raw tire. A method has been proposed in which the inner mold to which the green tire is mounted is directly carried into a vulcanization mold (outer mold for producing a tire), stored and vulcanized.

[0007] When removing the inner mold for tire production housed in the tire inner chamber of the vulcanized pneumatic tire from the pneumatic tire, first, the connecting member is removed from the core. Is removed, for example, in claim 2
The release means described in (1) is used. Next, after the support member and the gripping means are axially moved by the second moving means and inserted into the pneumatic tire, the radially inner end of one of the mold segments is gripped by the gripping means. Next, the first moving means moves the support member, the gripping means, and the mold segment radially inward of the pneumatic tire in a plane parallel to the tire equatorial plane, and removes the mold segment from the tire inner chamber.
Next, the holding means holding the mold segment by the second moving means is moved in the axial direction of the pneumatic tire, and the mold segment is taken out from the pneumatic tire. Then, such operations are repeated, and the die segments are sequentially removed from the tire inner chamber of the pneumatic tire. Since it is sufficient to provide only the first and second moving means for moving the support member and the gripping means in this way, the structure is simplified, and these support members and the gripping means are arranged in two directions in the radial and axial directions of the pneumatic tire. Since the mold segment can be removed only by moving in the direction, the work can be performed quickly and the efficiency is improved.

The tire manufacturing inner mold 13 assembled in this manner includes a vertically moving rod 53, a movable beam 51, and a movable base.
By the movement of 52, it is conveyed from the assembling means 71 to the conveyor 81, transferred to the conveyor 81, and then conveyed to the raw tire forming device by the traveling of the conveyor 81. Here, the above-described inner mold 13 for tire production is heated at a high temperature due to heat during vulcanization.
Since the air is cooled during the assembly and transportation by the conveyor 81, it is sufficiently cooled when transported to the green tire forming apparatus, and can be used as it is for green tire molding. When the inner mold 13 for tire production is removed from the assembling means 71 as described above, the cylinder 74 of the assembling means 71 is operated to retract the piston rod 75, thereby synchronously moving the support base 73 radially outward. And a circumferential gap is formed between them. This is because when the mold segments 18 are placed on these supports 73, the adjacent mold segments 18
This is to prevent a situation in which the members interfere with each other through the matching projection 19.
