Summary of the invention
(1) technical problems to be solved
The tire-mold by the state of molding side plate connected with contact surface with sectorial block mold, to be formed in inside
Enclosure space for forming tire.Sometimes, it if the contact surface in molding in the two bites the rubber of tire, can form
The outer surface of tire afterwards forms overlap (prominent rubber) and causes open defect.In addition, remaining on tire when overlap ruptures
When mold, the reason of overlap is transferred to the molding tire in subsequent handling and can also become open defect.
The present invention is conceived to such problems and completes, and its purpose is to provide one kind to prevent in side plate and sector
The contact surface of block mold bites rubber and is able to suppress the tire-mold of the open defect of tire.
(2) technical solution
The present invention takes following means to achieve the goals above.
That is, tire-mold of the invention is used for the enclosure space of forming tire in internal formation in the state of molding, and have
Have:
A pair of side plates, the configured separate on tire width direction, and inner surface is contacted with the sidewall of tire；And
Multiple sectorial block molds, the side of the pair of side plate along tire circumferential array circlewise, and inner surface
It is contacted with the fetus face of tire,
The side plate and the sectorial block mold are respectively provided with the contact surface to connect in the state of molding, the contact surface
Tire width direction inner terminal more leans on the outside of tire width direction positioned at the external surface than tire,
The inner surface of the sectorial block mold has projecting strip part, the tire width direction of the projecting strip part and the contact surface
Inner terminal is adjacent and circumferentially extends along tire, and in tyre equatorial section, the projecting strip part is than imaginary line more to tyre side
It is prominent, it the tire width direction outermost end of osseous part of the imaginary line connection for being formed a groove in the fetus face and described connects
The tire width direction inner terminal of contacting surface.
In addition, being also possible in tire-mold such as flowering structure, in tyre equatorial section, the projecting strip part buckling
Or bending.
In addition, in tire-mold, it is also possible to such as flowering structure, the jag of the projecting strip part is located at than the external surface
More on the outside of tire width direction.
In addition, in tire-mold, it is also possible to such as flowering structure, the jag of the projecting strip part is located at from the contact surface
Tire width direction inner terminal to the osseous part tire width direction outermost end tire radial height it is 50% below
Highly.
In addition, in tire-mold, it is also possible to such as flowering structure, in tyre equatorial section, the projecting strip part has
The arc sections being connect with the tire width direction inner terminal of the contact surface, and the radius of curvature of the arc sections is 2mm or more.
(3) beneficial effect
According to the present invention, in molding, the rubber that can be postponed unvulcanized tire using projecting strip part is reached contact surface and connect
Touching, therefore can prevent from biting rubber in contact surface and inhibit the generation of overlap, as a result, the appearance for being able to suppress tire lacks
It falls into.

Specific embodiment
Embodiments of the present invention will be described with reference to the accompanying drawings.
Firstly, before illustrating each structure of tire-mold, it is first (also simple below to the pneumatic tire manufactured with tire-mold
Referred to as " tire ") it is illustrated.As shown in Figure 1, tire 10 includes a pair of bead portion 11, with tyre bead；Sidewall 12,
Extend from each bead part 11 to the outside of tire radial direction D2；And fetus face 13, it is connected to the tire diameter in a pair of sidewall portion 12
To the outer end of D2, tyre surface is constituted.
In Fig. 1 (figure below is also the same), tire width direction D1 is left and right directions.In addition, tire radial direction D2 is wheel
The diametrical direction of tire 10, tire circumferential direction D3 (not shown in Fig. 1) are around the direction of tire rotary shaft.In addition, in Fig. 1, wheel
The tire radial direction D2 parallel with paper in tire radial direction D2 is up and down direction.In addition, equatorial plane S1 is and tire rotary shaft
Orthogonal face and be positioned at the face at the center of tire width direction D1.
As shown in Fig. 2~Fig. 5, the tire-mold 1 of present embodiment includes a pair of side plates 2,2, inner surface 21 and tire
10 sidewall 12 contacts；And multiple sectorial block molds 3, inner surface 31 are contacted with the fetus face 13 of tire 10.In addition, wheel
Placenta 1 has a pair of bead mold 4,4, chimeric for the bead part 11 of tire 10.In the present embodiment, tire-mold 1
Constitute a part that tire curing tire curing unit is formed and vulcanizing to unvulcanized tire.
A pair of side plates 2,2 separates on tire width direction D1 relative to the tire 10 being set to inside tire-mold 1 matches
It sets.In addition, multiple sectorial block molds 3 are configured at the side of a pair of side plates 2,2, and relative to being set to inside tire-mold 1
Tire 10 arranges circlewise along tire circumferential direction D3.
Moreover, side plate 2 can be on tire width direction D1 close to or away from addition, multiple relative to another side plate 2
Sectorial block mold 3 relative to side plate 2 can on tire radial direction D2 close to or away from.Tire-mold 1 can switch to Fig. 2 as a result,
With die opening state shown in Fig. 3 and Fig. 4 and molding state shown in fig. 5.
In die opening state, side plate 2 separates tire-mold 1 with sectorial block mold 3, therefore is able to carry out going out for tire 10
Enter.In addition, tire-mold 1 is in the state of molding, side plate 2 is pressed into contact with sectorial block mold 3, thus inside formed at
The enclosure space of type tire 10.
Side plate 2 and sectorial block mold 3 are respectively provided with the contact surface 22,32 to connect in the state of molding.In addition, side plate 2
