Structural schematic diagram when Fig. 1 die sinking limit.Fig. 1, Fig. 2, Fig. 3, Fig. 4 are please referred to, the tyre adjustable die limit in the present embodiment
Mechanism 100 includes pedestal 101, upper cover 102, lead ring 103, multiple sliding parts 110.Multiple sliding parts 110 are slidably connected to respectively
The medial surface P2 of lead ring 103, and it is circumferentially spaced on the medial surface P2 of lead ring 103；Have between adjacent sliding part 110
Gap f1.The inside of sliding part 110 is pattern block 105, the decorative pattern of the circumferential surface for forming tire.Wherein, sliding part 110 passes through
The realization of gib block 106 is slidably coupled to lead ring 103, so that sliding part 110 can be certainly after above mentioning lead ring 103 in die sinking
Opposite 103 slide downward of lead ring under the action of weight (actually appear sliding part 110 remains stationary, lead ring 103 moves up), leads in addition
It is to be obliquely installed to item 106, so that sliding part 110 has in the movement that opposite lead ring 103 glides drives pattern block 105 radially
Outside displacement component realizes that die sinking is detached from the decorative pattern circumferential surface of tire.Sliding part 110 in the present embodiment can be pattern block 105,
It is also possible to be formed by connecting by a sliding block 104 and pattern block 105.
In the present embodiment, multiple locating parts 10 are circumferentially connected on the medial surface P2 of the lead ring 103 of tyre adjustable die；
Locating part 10 is located in the gap f1 between the adjacent sliding part 110 of tyre adjustable die；The upper cover 102 of tyre adjustable die
Lower end surface is confined planes P5；Confined planes P5 and locating part 10 are corresponding in the axial direction of tyre adjustable die, so that locating part 10 can
In the axial uplink for axially trapping lead ring 103.According to 105 quantity of stress condition and pattern block, it is preferable that corresponding confined planes P5
Locating part 10 circumferentially be at least arranged 3 groups, the set-up mode of 4 as shown in Fig. 2 clearly group；And preferably,
Cloth setting；When being set as 3 groups, any two groups of angles between the line in the center of circle are less than 180 degree；When for 4 groups or more, until
Two groups including an angle between the line in the center of circle more than or equal to 90 degree combine less and one between the line in the center of circle
Angle be more than or equal to 180 degree two groups of combinations.
Cooperation referring to fig. 4, the locating part 10 of confined planes P5, when being opened 103 uplink of lead ring, lead ring is corresponded to by being arranged
103 will continue the lead ring of uplink then because locating part 10 is capped 102 limits with 10 uplink of locating part being attached to
103 will drive 102 uplink of upper cover by the limit until completing to be opened.It is limited in the present embodiment by 10 confined planes P5 of locating part
Mode realize die sinking, when existing tire-mold being avoided to be opened, the limit of upper cover 102 is limited by sliding part 110 and limited block
Position occurs 102 He of upper cover if occurring limited block fracture or sliding part 110, the damage of gib block 106 in production process
A possibility that sliding part 110, gib block 106 are fallen, has the advantages that safe and reliable.
Certainly, in the embodiments of the present invention, the restraining position that may also set up locating part 10 and confined planes P5 is being limited
On the basis of before the restraining position of position block, still retain the structure of limited block (not shown), using as further safety guarantee
Structure.
What the locating part 10 in the present embodiment can be set to clearly to show in diversified forms, such as Fig. 1, Fig. 4, locating part 10
Including the pedestal 11a being fixedly connected with lead ring 103, and vertically flexibly support the jacking block 12 on pedestal 11a；Jacking block 12
Loading end P1 of the upper surface as face confined planes P5；Certainly, in other embodiments, can also by jacking block 12 upper surface and
The upper surface of pedestal 11a is collectively as loading end P1.Optionally, referring to Fig. 1, there can be lower spill in the upper surface of pedestal 11a
At groove C1；Jacking block 12 is T-type structure, and its underpart is flexibly supported by a disc spring 13 in the bottom surface of groove C1；Jacking block 12
Top and the upper surface of pedestal 11a limit the lower limit position of jacking block 12；One passes through pedestal 11a from bottom to top and connects jacking block 12
Shaft shoulder screw 16 head of screw and pedestal 11a lower end surface limit jacking block 12 upper limit position；Jacking block 12 is defined to phase
To pedestal 11a between lower limit position and upper limit position resilient movement.Shaft shoulder screw 16 can be replaced by other connecting rods
Generation.As other embodiments, which also be can be set in the bottom (not shown) of upper cover 102.Referring to fig. 4, make
With principle are as follows: when die sinking, limit jacking block 12 promotes the bottom for arriving upper cover 102, and this trip is than 106 upper limit position block stroke of gib block
Small not damage limited block and gib block 106, it can be achieved that upper cover 102 limits first, wherein the main function of disc spring 13 is when upper
Lid 102 buffers upper cover 102 when falling on limit jacking block 12, prevents damage caused by impact.In other embodiments
In, disc spring 13 can be substituted with other suitable elastic components.
The locating part 10 of tyre adjustable die shown in Fig. 5 is using another set-up mode.Referring to Fig. 5, locating part 10 is wrapped
Include pedestal 11b, torsion block 14, torsional spring 15；Locating part 10 is fixedly connected on the medial surface P2 of lead ring 103；Reversing block 14 can be rotated
Ground is connected to pedestal 11b, rotational angle range by two limits of pedestal 11b turn face P4 be defined in the first rotation limit position and
Between second rotation limit position；It reverses block 14 to flexibly support by torsional spring 15 on pedestal 11b, and is pressed by 15 elasticity of torsional spring
In the first rotation limit position；And the elastic force of torsional spring 15 can be overcome in the lower pressure by upper cover 102 by reversing block 14
And it rotates to its second rotation limit position；Torsion block 14 is in the state of the second rotation limit position, and torsion block 14 is perpendicular
To bracketing upper cover 102, or torsion block 14 and pedestal 11b are jointly in vertical bracketing upper cover 102.Optionally, torsion block 14 corresponds to
One end of lid 102 is set as round and smooth arcwall face P3, and upper cover 102 pushes torsion block 14 in arcwall face P3, and deviates at pressing and turn round
The center of rotation of switch block 14, so that the lower pressure of upper cover 102 is able to drive torsion block 14 and rotates.The top of pedestal 11b is close to lead
103 axis side of ring, which offers, has the limiting slot C2 that two limits turn face P4；One of limit turns face P4 and is parallel to upper cover 102
Lower end surface, for limiting the second rotation limit position of torsion block 14.The structure of torsion block 14 also can be found in Figure 12
Referring to Fig. 5, Fig. 6, by the effect of torsional spring 15, torsion block 14 is in state obliquely, arc under molding state
Shape face P3 is towards upper cover 102.When die sinking, upper cover 102 pushes arcwall face P3, and drives the rotation of torsion block 14 to level, so as to turn round
14 support upper cover 102 of switch block.Under die opening state, reverses block 14 and upper cover 102 contacts, reverse connecing between block 14 and pedestal 11b
Contacting surface is preferably plane.By the effect of torsional spring 15, the state of block 14 obliquely, overhanging end circular arc are reversed under molding state
Setting can prevent locating part 10 and 105 back side of pattern block from interfering, and be conducive to save space.
In another embodiment, settable inelastic blocky locating part 10, the upper surface of locating part 10 is as limit
Face P5, and it is not provided with the elastic constructions such as disc spring 13 above-mentioned, torsional spring 15.It does not illustrate herein.
