A heating space for vulcanizing the tire is formed between the inner heating structure 21 and the outer heating structure 22, and at least a part of the inner heating structure 21 and at least a part of the outer heating structure 22 are respectively arranged inside the housing assembly 10; the inner membrane driving mechanism 30 is in driving connection with the inner heating structure 21 and drives the inner heating structure 21 to move along the vertical direction and the horizontal direction; the segmented mold driving assembly 40 is in driving connection with the external heating structure 22 and drives the external heating structure 22 to move in the vertical direction and the horizontal direction; when the electric heating mechanism 20 is switched from the mold opening position to the mold closing position, the inner film driving mechanism drives the inner heating structure 21 to move along the direction of increasing the radius and simultaneously drives the inner heating structure 21 to move along the direction towards the bottom end of the shell assembly 10, the segmented mold driving assembly 40 drives the outer heating structure 22 to move along the direction of decreasing the radius and simultaneously drives the outer heating structure 22 to move along the direction towards the bottom end of the shell assembly 10, and the heating space becomes smaller; when the electric heating mechanism 20 is switched from the mold closing position to the mold opening position, the inner film driving mechanism drives the inner heating structure 21 to move in the direction of decreasing radius while driving the inner heating structure 21 to move in the direction toward the top end of the housing assembly 10, the segmented mold driving assembly 40 drives the outer heating structure 22 to move in the direction of increasing radius while driving the outer heating structure 22 to move in the direction toward the top end of the housing assembly 10, and the heating space becomes larger.

In the case of the tread vulcanizer of the present application, since the electric heating mechanism 20 has the mold-opening position and the mold-closing position, the placement of the carcass to be vulcanized between the inner heating structure 21 and the outer heating structure 22 or the removal of the vulcanized carcass from between the inner heating structure 21 and the outer heating structure 22 can be achieved by switching the electric heating mechanism 20 between the mold-opening position and the mold-closing position. And because the tread vulcanizer also has inner membrane drive mechanism 30 and segmented mold drive assembly 40, electric heating mechanism 20 can switch between the mold opening position and the mold closing position under the action of inner membrane drive mechanism 30 and segmented mold drive assembly 40. Therefore, the tread vulcanizer in this application has solved the poor problem of tread vulcanizer performance among the prior art effectively.

In one particular embodiment of the present application, the inner heating structure 21 has a ring-shaped heating outer surface; the outer heating structure 22 is provided with an annular heating inner surface corresponding to the heating outer surface, a heating space is formed between the heating outer surface and the heating inner surface, the inside of the inner heating structure 21 and the inside of the outer heating structure 22 are respectively provided with at least one heating cavity 23, heat conduction oil is contained in the heating cavities 23, and at least one heating rod for heating the heat conduction oil is respectively arranged in each heating cavity 23. The inner heating structure 21 comprises a plurality of heating inner modules 211, the plurality of heating inner modules 211 are respectively connected with the inner membrane driving mechanism 30, each heating inner module 211 is provided with at least one heating cavity 23, and the plurality of heating inner modules 211 are arranged around the circumference of the inner membrane driving mechanism 30 and enclose a heating outer surface; the external heating structure 22 comprises a plurality of heating external modules 221, the plurality of heating external modules 221 are respectively connected with the segmented mold driving assembly 40, each heating external module 221 is provided with at least one heating cavity 23, and the plurality of heating external modules 221 surround to heat the inner surface. Also, the heating outer block 221 includes an arcuate seat 2211 and a segmented mold. The arc-shaped seat 2211 is provided with a heating cavity 23, and the arc-shaped seat 2211 is connected with the segmented mold driving assembly 40; the segmented mold is detachably disposed on the side of the arcuate seat 2211 facing the inner heating structure 21.

Since the electric heating means 20 have an inner heating structure 21 and an outer heating structure 22, it is possible to place the carcass to be vulcanized in a heating space between the inner heating structure 21 and the outer heating structure 22, so as to heat the carcass by heating the outer surface and the inner surface, thus achieving vulcanization. Therefore, during the use of the electric heating mechanism 20, the tire body can be fitted over the outer surface of the inner heating structure 21, that is, over the heating outer surface. And because the inner heating structure 21 and the outer heating structure 22 are respectively provided with a heating cavity 23 containing heat conduction oil and a heating rod, when the electric heating mechanism 20 is used, the heat conduction oil can be heated by the heating rod, so that the heat conduction oil can heat the inner heating structure 21 or the outer heating structure 22, and the heating of the inner heating structure 21 and the outer heating structure 22 on the tire body is realized. Moreover, the internal heating structure 21 and the external heating structure 22 are heated through the heat conduction oil, so that the internal heating structure 21 and the external heating structure 22 can be heated more uniformly, and the tire body is further heated more uniformly. The vulcanization effect of the electric heating mechanism 20 is effectively ensured by this arrangement. Simultaneously, because electric heating mechanism 20 in this application no longer uses traditional steam heating mode, so no longer need lay the thermotechnical pipeline, electric heating mechanism 20 in this application has low in production cost, advantage that occupation space is little. Therefore, the electric heating mechanism 20 in the present application effectively solves the problem of high tread vulcanizing cost of the tread vulcanizing machine in the prior art.

It should be noted that, in this application, after the tire body is heated by the plurality of heating inner modules 211 or the tire body is sleeved on the plurality of heating inner modules 211, the plurality of heating inner modules 211 can be surrounded into a circle, so as to ensure the heating and vulcanizing effects of the tire body. Therefore, the inner film driving mechanism can drive the different heating inner modules 211 to move in the radial direction, respectively, and all the heating inner modules 211 do not move together during the movement of the plurality of heating inner modules 211, but can perform the radial movement in a plurality of times. Meanwhile, in order to ensure that the plurality of heating inner modules 211 can enclose a complete circle, the shapes of two adjacent heating inner modules 211 can be different, and the purpose of the arrangement is to ensure that the adjacent heating inner modules 211 can be spliced with each other. Likewise, the plurality of heating outer modules 221 may be formed in a circle, and the circle formed by the heating outer modules 221 is concentric with the circle formed by the heating inner module 211.

In addition, the operation forms of the heating inner module 211 and the heating outer module 221 are not limited in the present application as long as the tire body can be smoothly vulcanized.

In one embodiment of the present application, the inner membrane driving mechanism 30 includes an inner membrane axial expansion assembly and an inner membrane radial expansion assembly, the inner membrane radial expansion assembly is sleeved on the inner membrane axial expansion assembly, the inner heating structure 21 is connected to the inner membrane radial expansion assembly, and the inner membrane radial expansion assembly includes: a first driving part 31, the first driving part 31 being provided on the housing assembly 10; a first pull tray 32; the first connecting rod 33, the first connecting rod 33 and the first pull plate 32 are connected with the second pull plate 34; the second connecting rod 35, the second connecting rod 35 is connected with the second pull disc 34, the first connecting rod 33 and the second connecting rod 35 are parallel to each other, the first pull disc 32 and the second pull disc 34 are parallel to each other and are arranged at intervals along the axial direction of the first connecting rod 33, and the first driving part 31 is respectively in driving connection with the first connecting rod 33 and the second connecting rod 35 and drives the first pull disc 32 and the second pull disc 34 to move along the directions of approaching to each other or separating from each other through the first connecting rod 33 and the second connecting rod 35; the number of the push-pull rods 36 is the same as that of the heating inner modules 211, the push-pull rods 36 correspond to that of the heating inner modules 211 one by one, the push-pull rods 36 are divided into two groups, two adjacent heating inner modules 211 are respectively connected with different groups of push-pull rods 36, one group of the push-pull rods 36 is connected with the first pull disc 32, the other group of the push-pull rods 36 is connected with the second pull disc 34, and an included angle is formed between each push-pull rod 36 and the horizontal direction.

In the present application, the first link 33 and the second link 35 are arranged along the axial direction of the tread vulcanizer, that is, the axial direction of the first link 33 and the second link 35 is perpendicular to the moving direction of the inner heating structure 21 when moving in the radial direction. When the first driving portion 31 drives the first connecting rod 33 and the second connecting rod 35 respectively and makes them move in respective axial directions, the first connecting rod 33 can drive the first pull disc 32 to move along the axial direction of the first connecting rod 33, and the second connecting rod 35 can drive the second pull disc 34 to move along the axial direction of the second connecting rod 35, so that the first pull disc 32 and the second pull disc 34 respectively drive different push-pull rods 36 to move. Due to the included angle between the push-pull rod 36 and the horizontal direction, when different push-pull rods 36 are driven by the first pull disc 32 or the second pull disc 34, the included angle between the push-pull rod 36 and the horizontal direction changes, and the push-pull rod 36 can drive the inner heating structure 21 to perform radial movement. Make tread vulcanizer compare with traditional tread vulcanizer in this application like this, have simple structure, the processing degree of difficulty is little, long service life, low maintenance frequency advantage such as.

Preferably, the first connecting rod 33 and the second connecting rod 35 both pass through the first pull plate 32 and the second pull plate 34, the first pull plate 32 has an avoiding hole avoiding the second connecting rod 35, and the second pull plate 34 has an avoiding hole avoiding the first pull plate 32, so as to ensure that when the first connecting rod 33 drives the first pull plate 32 to move, the second pull plate 34 cannot be driven by the first connecting rod 33, and when the second connecting rod 35 drives the second pull plate 34 to move, the first pull plate 32 cannot be driven by the second connecting rod 35. Of course, in the present application, it is also possible that the first connecting rod 33 passes through the first pulling disk 32 and the second pulling disk 34, respectively, and the second connecting rod 35 passes through only the second pulling disk 34. Alternatively, the second link 35 passes through the first and second pulling disks 32 and 34, respectively, while the first link 33 passes through only the first pulling disk 32.

In addition, in the present application, when the first connecting rod 33 and the second connecting rod 35 respectively drive the first pull plate 32 and the second pull plate 34 to move, the first connecting rod 33 and the second connecting rod 35 do not move simultaneously, but the first connecting rod 33 moves first, and after the first connecting rod 33 completes the movement, the second connecting rod 35 drives the second pull plate 34 to move. Or the second connecting rod 35 moves first, and after the second connecting rod 35 completes the movement, the first connecting rod 33 drives the first pull disc 32 to move. Thereby ensuring that the plurality of heating inner modules 211 do not have a problem of blocking or colliding with each other when moving in the radial direction.

It should also be noted that in one embodiment of the present application, the lengths of the two sets of push-pull rods 36 are different, and the lengths between the same set of push-pull rods 36 are the same. The purpose of this arrangement is to ensure that when the two sets of push-pull rods 36 drive the heating inner modules 211 to move in the radial contraction direction, after the heating inner modules 211 are moved in place, the adjacent two heating inner modules 211 can be staggered in the radial direction, so as to ensure that all the heating inner modules 211 can normally move in the radial direction.

In a specific embodiment of the present application, the housing assembly 10 includes an outer ring 11 and a guide structure 12, the outer ring 11 has a vulcanization opening, and the guide structure 12 is disposed on an inner side wall of the outer ring 11 and has a first guide inclined plane 121 disposed toward a central axis of the outer ring 11, an included angle is provided between the first guide inclined plane 121 and the central axis, the segmented mold driving assembly 40 is disposed on a side of the guide structure 12 close to the central axis of the tread vulcanizer, the segmented mold driving assembly 40 includes: a second driving part 41, the second driving part 41 being disposed on the housing assembly 10, at least a portion of the second driving part 41 being capable of moving in an axial direction of the central axis relative to the housing assembly 10, and a distance from the first guide slope 121 to the central axis gradually increasing in a direction away from the second driving part 41; the number of the segmented mold mounting structures 42 is multiple, the segmented mold mounting structures 42 correspond to the plurality of heating outer modules 221 one by one, the heating outer modules 221 are arranged on the corresponding segmented mold mounting structures 42, at least one part of the segmented mold mounting structures 42 is arranged on the second driving portion 41, and the segmented mold mounting structures 42 are provided with second guide inclined surfaces 421 matched with the first guide inclined surfaces 121, so that the segmented mold mounting structures 42 can move along the first guide inclined surfaces 121.

Because the segmented mold driving assembly 40 comprises the second driving part 41 and the segmented mold mounting structure 42, the heating outer module 221 can be mounted on the segmented mold mounting structure 42, and the segmented mold mounting structure 42 is driven by the second driving part 41 to move, so that the segmented mold mounting structure 42 can drive the heating outer module 221 to move together. In addition, in the process that the second driving portion 41 drives the segmented mold mounting structure 42 to move along the axial direction, since the segmented mold mounting structure 42 has the second guide inclined surface 421 matched with the first guide inclined surface 121, the actual moving mode of the segmented mold mounting structure 42 is that the radial movement is still existed while the axial movement is performed, that is, the radial movement is performed along the first guide inclined surface 121, and further, the position switching of the heating outer module 221 is realized. Therefore, the tread vulcanizing machine in the application is more compact in structure through the arrangement, the die opening space does not need to be reserved, and the production cost of the annular tread vulcanizing machine is reduced. Therefore, the problems of large occupied space and poor use performance of the annular tire tread vulcanizing machine in the prior art are effectively solved.

Specifically, the second driving portion 41 includes: an axial drive cylinder 411, the axial drive cylinder 411 being disposed on the housing assembly 10; and the supporting plate 412, the axial driving oil cylinder 411 and the supporting plate 412 are in driving connection and drive the supporting plate 412 to move along the axial direction of the central shaft, and the segmented mold mounting structure 42 is arranged on the supporting plate 412 and can move relative to the supporting plate 412. Moreover, the plane of the side of the supporting plate 412 contacting with the segmented mold mounting structure 42 is parallel to the radial direction of the central shaft, the supporting plate 412 is provided with a plurality of first guide grooves extending along the radial direction of the central shaft corresponding to the plurality of segmented mold mounting structures 42, and the segmented mold mounting structure 42 is provided with first guide protrusions matched with the first guide grooves, so that the segmented mold mounting structure 42 can move along the first guide grooves. Because in the process that the second driving part 41 drives the segmented mold mounting structure 42 to move, the supporting plate 412 only moves along the vertical direction, and the moving direction of the segmented mold mounting structure 42 is the extending direction of the first guide inclined surface 121, relative displacement can exist between the segmented mold mounting structure 42 and the supporting plate 412, and the first guide groove and the first guide protrusion are arranged to guide and limit the movement of the segmented mold mounting structure 42, so that the normal operation of the tread vulcanizing machine is ensured.

It should be noted that the side of the first guide slope facing the second guide slope has a second guide groove, and the second guide slope has a second guide protrusion cooperating with the second guide groove.

Of course, in the present application, the outer heating module may be connected to the supporting plate and the segmented mold mounting structure, respectively, and the outer heating module has a first guiding protrusion engaged with the first guiding groove, and the supporting plate drives the outer heating module to move, and the outer heating module defines a moving direction in the moving process under the engagement of the segmented mold mounting structure and the guiding structure.

In the present application, the tread vulcanizer is a vertical tread vulcanizer. Thus, axial refers generally to the vertical direction and radial refers to the horizontal direction.
