Dynamic portion 314 and third driving portion 324 all have the mutually matched conical surface, under first state, multiple first movable blocks 31 and multiple
Second movable block 32 forms middle part annular dish structure with hole, and the first driving portion 221 is for being placed in the annular dish structure
The inside in hole, in steel ring 22 in the motion process of support member 10, the first driving portion 221 of steel ring 22 and the first movable block
31 the second driving portion 314, the third driving portion 324 of the second movable block 32 contact, and apply pressure to it, and drive first to live
Motion block 31 and the second movable block 32 are mobile to the direction far from central axes 40, when steel ring 22 is transported on the direction far from pedestal 11
When dynamic, the first movable block 31 and the second movable block 32 realize reset under the action of the first spring 14 and second spring 16.In conjunction with
Fig. 2 and Fig. 3, steel ring 22 are installed on clamp ring 21 by fastener 23, in general, by applying external force to clamp ring 21 to drive
Steel ring 22 is mobile.It should be understood that the outer surface of the first driving portion 221 of the steel ring 22 is the lateral surface of rotary table, in the first shape
Under state, the inner surface of annular dish structure is the medial surface of rotary table.
In conjunction with Fig. 2, Fig. 2 shows the first movable block 31 and the second movable block 32 under the action of steel ring 22, be located remotely from each other,
Realize molding, telescopic mounting 100 is under first state at this time, the first movable block 31 and second in conjunction with Fig. 3, shown in Fig. 3
Movable block 32 moves closer to central axes 40, realizes die sinking, telescopic mounting 100 is under the second state at this time.
It should be noted that needing hydraulic cylinder or transmission shaft etc. external during going to molding state from die opening state
Driving device provides driving force, pushes clamp ring 21, and steel ring 22 is driven to move on the direction of pedestal 11.A kind of implementation
Under, the piston rod or transmission shaft etc. sequentially pass through the hole on hole on pedestal 11, the hole of annular dish structure, steel ring 22 and clamp ring 21
And it acts on clamp ring 21.
The circumferential two sides of first movable block 31 have the first contact surface 311, and the circumferential two sides of the second movable block 32 have the
Two contact surfaces 321, in the first state, the outer profile of the outer profile of multiple first movable blocks 31 and multiple second movable blocks 32 can
To form continuous molded surface, the tyre bead of tire can be helped to form required shape, while can also mould along tyre bead
One smooth surface.
In conjunction with Fig. 2 and Fig. 3, in general, the first movable block 31 is leaning on during the molding state is gone under die opening state
It is moved (i.e. being moved radially outward along annular dish structure) on the direction of nearly central axes 40, the second movable block 32 is close to central axes
40 direction also proximates steel ring 22 while mobile mobile (moving obliquely).In this process, 31 He of the first movable block
It is possible to wear between the second adjacent movable block 32, it is serious, it is also possible to which that the phenomenon that causing die sinking failure occurs the
One movable block 31 and the second movable block 32 are interfered and can not be opened.Likewise, when going to molding state from die opening state, the
One movable block 31 moves on the direction far from central axes 40, and the second movable block 32 is same the direction movement far from central axes 40
When it is mobile also as steel ring 22 and to mobile (moving obliquely) close to the direction of floating ring 12.In this process, first
It is possible to wear between movable block 31 and the second adjacent movable block 32, it is serious, it is also possible to molding be caused to fail
, there is the first movable block 31 in phenomenon and the second movable block 32 is interfered and can not be molded.In the present embodiment, by making adjacent
One movable block 31 and the second movable block 32, which are not contacted or contacted in moving process, generates the lesser mode of interaction force, can be with
Above-mentioned phenomenon is avoided to occur.
In conjunction with Fig. 4-Fig. 6, in the present embodiment, the first contact surface 311 and the second contact surface 321 are and central axes 40 tilt
Plane, on driving part 20 to the direction of support member 10, the second contact surface 321 of the second movable block 32 is close to second
Side inside movable block 32 upwardly extends, and under first state, using the plane perpendicular to central axes 40 as cross section, central axes 40 exist
It is projected as midpoint on cross section, the figure that molded surface is intercepted by cross section is the second contact using midpoint as the circle in the center of circle
The figure that face 321 is intercepted by cross section is straight line 34, straight line 34 and circular radial skew.
It should be understood that being described in conjunction in Fig. 6 with the relative position in Fig. 6, the second contact surface 321 is from top to bottom
Direction on, upwardly extended towards the side of inside close to the second movable block 32, that is to say, that away from adjacent first
The side of movable block 31 upwardly extends.
Movable part 30 in Fig. 4 and Fig. 5 is under first state, it is possible to understand that, the dish knot in a ring of movable part 30
Structure, the figure that the outer profile of annular dish structure is intercepted by cross section are using midpoint as the circle in the center of circle.First movable block 31 can only
Along moving radially for annular dish structure, the second movable block 32 not only can moving radially along annular dish structure, can also be in
Axis 40 is mobile (can be understood as the axial movement along annular dish structure), i.e., moves obliquely or obliquely.In the present embodiment,
First contact surface 311 and the second contact surface 321 are relative to the inclined plane in central axes 40, and 311 He of the first contact surface
The figure that the mating surface formed after the fitting of second contact surface 321 is intercepted by cross section is straight line 34, the extending direction of the straight line 34
With the radial skew of annular dish structure, in this way, during open mold, the movement of the second movable block 32 will not be by the first activity
Block 31 constrains, and free movement may be implemented, meanwhile, the movement of the second movable block 32 will not be constrained by the first movable block 31,
Free movement may be implemented.Therefore, two adjacent movable blocks will not be in contact in the second condition.
It should be noted that optional, the first contact surface 311 and the second contact surface 321 may be cambered surface or curved surface
Deng alternatively, the first contact surface 311 and the second contact surface 321 are formed by several continuous and non-coplanar plane, as long as the two energy
Enough fittings in the second condition and do not contact still.
Optionally, the quantity of the first movable block 31 is three, and the quantity of the second movable block 32 is three, the second movable block 32
Two sides corresponding to two straight lines 34 to be formed by angle be a；
