Formwork 6 is made of segment 14, lasso 15, upper mold coverboard (container plate) 16 and lower form boarding 17.
Segment 14 is screwed multiple by each sectorial block 20 respectively to aftermentioned tire vulcanization mold 2
(being here nine) is constituted.The inner surface of each segment 14 follows the outer surface of sectorial block 20, and outer surface is from below
And the inclined surface (peripheral side circular conical surface) gradually expanded to outside diameter is constituted.Each segment 14 be radially reciprocally moveable it is upper
Sliding block 18 supports.
Lasso 15 is hollow cylindrical, and cope plate 3 is fixed in end face thereon.Also, with the lifting action of lift cylinders 7 into
Row lifting.The inner surface of lasso 15 with toward lower end side from gradually rolling oblique inner circumferential side circular conical surface to outer diameter and constituting.Set
The inner circumferential side circular conical surface of circle 15 and the peripheral side circular conical surface of each segment 14 are formed as sliding (slide) along its circular conical surface, (example
Such as, pass through the structure as tenon and dovetail groove) it does not separate each other.As a result, if lasso 15 declines, its inner circumferential side circle is utilized
The conical surface pushes the peripheral side circular conical surface of each segment 14, enables the segment 14 to outside diameter extended mode to inside
The state that diameter side annularly connects is mobile.
It is fixed with top shoe 18 in the peripheral side lower surface of upper mold coverboard 16, it is solid in the inner circumferential side lower surface of upper mold coverboard 16
Surely there is aftermentioned upper mold 21.Upper mold coverboard itself is fixed on the lower surface of top board 4.As a result, if elevating lever 8 is gone up and down,
Upper mold 21 and segment 14 (sectorial block 20 comprising being fixed on segment 14) and 16 1 raising of top board 4 and upper mold coverboard
Drop.
It is fixed with sliding block 19 in the peripheral side upper surface of lower form boarding 17, it is solid in the inner circumferential side upper surface of lower form boarding 17
Surely there is aftermentioned lower mold 22.On sliding block 19, when molding, is placed with segment 14, and radially slideably supports.Under
Form boarding 17 is fixed on the upper surface of lower platen 5 in itself.
Tire vulcanization mold 2 is made of sectorial block 20, upper mold 21 and lower mold 22.
Sectorial block 20 is made of aluminium alloy, and multiple (being here nine parts) are circumferentially divided into along tire, to internal diameter sidesway
It is annularly connected in the state of dynamic.The inner surface of each sectorial block 20 is by the molding tyre surface forming surface structure of fetus face for making tire
At.
Upper mold 21 is formed as cyclic annular, is fixed with upper bead ring 23 in its inner peripheral portion.Upper mold 21 is fixed on upper mold coverboard
16, and gone up and down with the lifting action of elevating lever 8.In decline, make it possible to press crude tyre by upper bead ring 23
The bead part of GT.As a result, by the lower surface of the lower inner surface of upper mold 21 and upper bead ring 23, the side wall of tire is formed
(sidewall) portion and the portion tyre bead (bead).
Lower mold 22 and the upper mold 21 are identically formed as ring-type, are fixed with lower bead ring 24 in its inner peripheral portion.
In the vulcanization forming machine 1 for being equipped with the tire vulcanization mold 2 being made of above structure, it is as described below as be arranged
(set) crude tyre GT after being closed mold, is molded according to the flow chart (flowchart) of Fig. 5 and is carried out crude tyre
The sulfidization molding of GT.
That is, under die opening state shown in (a) in Fig. 2, by crude tyre GT so that its axis direction is towards upper and lower side
Formula is placed on lower mold 22.At this point, the bead part for being located below side is positioned at lower bead ring 24.
Also, as shown in (b) in Fig. 2, supplying air into capsule 13 makes its expansion, is kept by its outer surface raw
The medial surface (step S1) of tire GT.Crude tyre GT is supported by lower bead ring 24 and capsule 13 as a result, with lower mold 22 in non-
Contact condition.
Then, by driver 25, upper mold 21 and sectorial block 20 is made to decline (step by elevating lever 8 and lift cylinders 7
Rapid S2).At this point, the lowering action of upper mold 21 and sectorial block 20 passes through the first lowering action for declining with the first decrease speed
(step S2-1), the intermediate stopping for temporarily ceasing it act (step S2-2) and to be lower than the second of the first decrease speed
Second lowering action (step S2-3) Lai Jinhang of decrease speed decline.The velocity variations respectively acted are shown in the chart of Fig. 6.
In the first lowering action, as long as the decrease speed of upper mold 21 and sectorial block 20 is set as and same mark in the past
Quasi velosity.Specifically, as long as by the decline before being closed from the decline of upper mold 21 and sectorial block 20 to mold
Speed is set as 0.3m/s~2.0m/s.But due to executing intermediate stopping movement and the second decline described below
Movement, therefore also can be set as than the velocity interval faster.
In intermediate stopping movement, as shown in (b) in Fig. 2, in the crude tyre GT that will be kept by capsule 13 in axle center
When width dimensions on direction are set as L, meet in the distance l from the upper end of crude tyre GT (bead part) to the lower end of sectorial block 20
L≤3/4L, the stop position for preferably satisfying l≤1/2L temporarily stop the lowering action of upper mold 21.Setting stops in this way
Stop bit is set, and can prevent sectorial block 20 from unchangeably colliding with sliding block 19 with the first decrease speed.In addition, dwell time is set as
2 seconds hereinafter, crude tyre GT will not be caused to cure before sulfidization molding due to mold temperature.
In the second lowering action, the decrease speed of upper mold 21 and sectorial block 20 is set to be lower than first decline
Second decrease speed of speed (standard speed).Second decrease speed is 30% or more 80% or less the first decrease speed.If
30% of second decrease speed less than the first decrease speed will lead to crude tyre then until mold closure will expend the excessive time
GT cures before molding.On the other hand, if the second decrease speed is more than the 80% of the first decrease speed, cannot sufficiently inhibit
Speed when sectorial block 20 is abutted with sliding block 19 may cause damage.But by reduction of speed under the first of the first lowering action
Degree be set to it is faster than standard speed in the case where, need to become the lower limit value (30%) of the second decrease speed and upper limit value (80%)
More smaller ratio.
In the second lowering action, as shown in (c) in Fig. 2, upper bead ring 23 and crude tyre GT's is located above side
Bead part abuts.Also, as shown in (d) in Fig. 2, after deforming crude tyre GT by bead part, upper mold 21 and life are taken turns
Tire GT is abutted.Also, if upper mold 21 drops to molding and completes position, and as shown in (e) in Fig. 2, crude tyre GT becomes quilt
State clamped by upper mold 21 and lower mold 22.
Upper mold 21, which drops to after position is completed in molding, continues to the decline carried out by lift cylinders 7, makes lasso 15
Square side is mobile downwardly together with cope plate 3.The inner circumferential side circular conical surface of lasso 15 pushes the peripheral side circular cone of segment 14 as a result,
Face.In turn, make the sectorial block 20 being fixed in segment 14 mobile to internal diameter side.
At the time of gap g between sectorial block 20 circumferentially arranged side by side is 20mm or less (step S3), execution makes
The preceding stopping movement (step S4) temporarily ceased by the decline that lift cylinders 7 are carried out.For the gap between sectorial block 20 whether
It is by when the height dimension of segment 14 is set as H, according to from segment for 20mm hereinafter, as shown in (e) in Fig. 2
Whether the distance h of lower end position of 14 lower end position to lasso 15 meets 3/4H >=h >=1/2H and is judged.In addition,
Can gap between the size and sectorial block 20 of the pre-recorded decline carried out by lift cylinders 7 relationship, be based on its result
To judge.
Fig. 3 indicates the state for a part of sectorial block 20 to the mobile midway in internal diameter side.Sectorial block 20 is mobile
Halfway, as shown in the double dot dash line in Fig. 3, it some times happens that positional shift.At this point, the gap of two sectorial blocks 20 of diagram exists
Internal side diameter broadens, and narrows to outside diameter.Therefore, sectorial block 20 is made to advance to internal diameter side is mobile by keeping the posture unchangeably,
Crude tyre GT is readily able to be clamped by the gap.By stopping movement before executing, fan can be corrected using the elastic force of crude tyre GT
The positional shift of shape block 20 and appropriate location.
In addition, in preceding stopping movement, because dwell time is more than that will lead within 2 seconds crude tyre GT before being molded by sulphur
Change.Therefore, dwell time is set as 2 seconds or less (step S5).
Therefore, if restoring the movement (step S6) of sectorial block 20, the rubber that can be eliminated between sectorial block 20 is bitten,
And keep all sectorial blocks 20 consistently mobile to internal diameter side.In addition, crude tyre GT will not be caused to cure before molding.
Then, if cope plate 3 abuts (step S7) with top board 4, stop the decline (step carried out by lift cylinders 7
Rapid S8).As a result, shown in (f) in crude tyre GT such as Fig. 2, pushed in outside by upper mold 21, lower mold 22 and sectorial block 20,
The state that inside is pushed by capsule 13.In top board 4 and lower platen 5 (no matter die opening state and molding state) flowing has always
The heat exchange medium of temperature adjustment is carried out to enable crude tyre GT in a manner of the vulcanization of defined curing temperature.Make raw wheel as a result,
Tire GT sulfidization molding completes tire.Mold is opened to take out the tire of completion.
In this way, passing through the first decline first according to the sulfidization molding of the crude tyre GT carried out using above-mentioned vulcanization forming machine 1
Movement, intermediate stopping movement and the second lowering action carry out the decline of upper mold 21 and sectorial block 20.Also, in the second decline
In movement, speed when sectorial block 20 is abutted with sliding block 19 is set as the second decrease speed sufficiently reduced.Therefore, even if fan
Shape block 20 is abutted with sliding block 19 will not act on very big impact force, to prevent its damage.In addition, in clamping process,
When keeping sectorial block 20 mobile to internal diameter side, at the time of the gap between sectorial block 20 becomes before 20mm or less is abutted later
Temporarily cease it.It therefore, can be appropriate location by the position correction of each sectorial block 20, to prevent crude tyre GT from biting fan
Between shape block 20.
In addition, various modifications may be made the present invention is not limited to structure documented by above embodiment.
It in the above-described embodiment, is stopping movement among being executed between the first lowering action and the second lowering action,
But be also not and centainly need the intermediate stopping movement, as long as speed when sectorial block 20 is abutted with sliding block 19 reaches under second
Reduction of speed degree is sufficient.For example, the can be executed as shown in fig. 7, after the first lowering action, not execute intermediate stopping movement
Two lowering actions.Alternatively, it is also possible to as shown in figure 8, the second lowering action the second decrease speed not instead of constant speed, set
It is set to gradually slack-off.But intermediate stopping movement being arranged by centre, movement can be made conscientiously, make sectorial block 20 accurately with
The decline of second decrease speed.It in turn, can also be as shown in figure 9, holding running velocity from the first decrease speed to the second decrease speed
The speed-down action gradually decreased, to replace intermediate stopping to act.
In the above-described embodiment, however it is not limited to make the decrease speed of sectorial block 20 in the first lowering action and the second decline
The variation of this two-stage is acted, can also make velocity variations (drop with more than three-level (according to circumstances can also be infinitely) as needed
It is low).
