The pressure medium of supply HTHP in air bag 3.Thus, the unvulcanized tire A strengths of heated condition are pressed into sulfurizing mould 2
Inner surface and carry out heating pressurization.
Pressure medium is made up of the mixed gas of the inert gases such as nitrogen or inert gas and vapor, higher than described
Used under such as 24 air pressure of warm medium high pressure.In addition pressure medium passes through the supply and discharge stream 16, is heated to such as 150 DEG C
Left and right and supplied.In addition, in pressure period S2, pressure medium is in air bag 3 as the mixed gas with heating medium
Heating pressurization is carried out to unvulcanized tire A.Pressure period S2 activity time T2 is substantially to subtract work from activity time T0
Sequence time T1 value.
In addition, also can be merely with the heating period based on heating medium without the pressure period S2 based on pressure medium
S1 carries out sulfidization molding.In this case, as it was previously stated, it is preferred that changing the pressure for heating medium by the multistage in midway.
Now, heating period S1 activity time T1 is the 100% of the activity time T0.
Moreover, in the present invention, in the inside of the air bag 3, the sea of the water imbibition with continuous air bubbles is accommodated with advance
Continuous body 20.The condensed water D for the bottom that the cavernous body 20 absorbs the liquefaction of heating medium in vulcanization process S and lodged in air bag 3
At least a portion.Thereby, it is possible to reduce condensed water D water level, the position for the producing condensed water D i.e. lower section of tire can be reduced
The temperature on the sidewall of side and the temperature difference at other positions.
As shown in figure 3, in the vacuum stages S3, being situated between after sulfidization molding by vacuum from the air bag 3 discharge heating
Matter and make the atrophy of air bag 3, and from the tire A0 after vulcanization take out air bag 3.Now, in vacuum stages S3, cavernous body 20 is inhaled
The condensed water D received is extruded due to the vacuum from cavernous body 20, and from the exhaust outlet 15B together with heating medium
(being supply and discharge mouthful 15 in this example) discharge.
It is preferably more with the higher hydroxyl of water compatibility chemical group with containing here, for the cavernous body 20
Into.In addition, it is also preferred that proportion is smaller, water retentivity is higher, humidity resistance near 200 DEG C, drug resistance, slightly solubility and
Extrude the excellent durability in terms of bending.From such a viewpoint, as cavernous body 20 can be preferred to use as solid into
Divide the foam sponge (so-called cellulose sponge) of the continuous air bubbles containing cellulose.Additionally it is possible to contain the plant such as cotton
Fibres are used as reinforcing fiber.
In the cellulose sponge, it is integrated with water because having compared with polyhydroxy, therefore easily, and using based on small gas
The capillarity of bubble plays oneself water imbibition.Therefore, can quickly it be absorbed water without pressure.In addition, because being continuous gas
Bubble, therefore moisture can be substantially introduced into all bubbles, and water absorption can be improved.In addition, in cavernous body 20, it is excellent
It is below 0.10g/cc to select proportion, if too small more than voidage if the proportion, causes the significantly drop of absorption speed and water absorption
It is low.
In addition, for cavernous body 20, it is also desirable to which the retentivity of the water absorbed is excellent.Therefore use in this example can inhale
Receive and keep the sponge of the water of more than 10 times of weight of the quality of cavernous body 20.In order to obtain such retentivity, described
In cellulose sponge, suitably using bubble average pore size 0.7mm~2.2mm (particulate~middle grain) scope sponge.
So, the retentivity of water can be improved by the optimization of compatibility and average pore size.
Cavernous body 20 is stood 10 minutes after absorbing water, determine and eliminate the weight G1 of leakage part, and according to before water suction
Cavernous body 20 weight G2 difference, the retentivity of the water is shown as following formula (1).
(G1-G2)/G2——(1)
If polyurethane sponge etc., in the case of above-mentioned average pore size is employed, institute is made by standing
The water of absorption flows out because of deadweight, can not obtain the retentivity of above-mentioned water.
In addition, the water level in order to reduce condensed water D, the cumulative volume Va of cavernous body 20 is preferably heating period S1 air bag 3
Internal capacity Vb 1%~60%.The cumulative volume Va is the cumulative volume under the nature placed in an atmosphere.In totality
In the case that product Va is less than 1%, it is difficult to fully reduce condensed water D water level.If conversely more than 60%, hindering unvulcanized tire
A's is put into operation.From such a viewpoint, it is also preferred that cumulative volume Va lower limit is more than 2%, the upper limit be 40% with
Under.In addition, in the case of riding tire for vehicles, such as the inside air bag volume Vb relative to 34.5 liters produces about 2.0 liters
Condensed water.
