Description

Technical Field

[0001] This utility model relates to a tooling, specifically an auxiliary tooling for a through hole in a tire mold vent. Background Technology

[0002] Tire molds are key equipment used for the vulcanization and molding of various types of tires. Depending on their structure and application, tire molds can be categorized into several types, including movable molds, two-piece molds, tire tread molds, tire sidewall molds, tire base molds, and complete tire mold sets. Ventilation holes are also provided on the tire molds, which play a crucial role in the tire manufacturing process: expelling air to prevent interference with the vulcanization process and ensuring that the mold cavity is completely filled with rubber, thus producing a tire with a perfect surface.

[0003] During the use of tire molds, tire rubber material can seep into the vents. Over time, these vents are prone to blockage and failure. Currently, some mold manufacturers equip the vents with ventilation valves to reduce blockage. However, with numerous vents on tire molds, equipping each with a ventilation valve would inevitably lead to a significant increase in production costs. Furthermore, the ventilation valves themselves are also susceptible to blockage by tire rubber material seeping in and causing them to fail.

[0004] Another approach is to clear the vent after it is found to be blocked, restoring its original function. The conventional venting process requires initial cleaning of the blockage using a pointed tool, followed by further cleaning with an air gun or cleaning agent. However, due to the large size and weight of the tire mold itself, it is usually placed directly on the ground for processing. This requires workers to squat or bend over continuously to clear the vents, resulting in extra effort and increasing the risk of occupational diseases.

[0005] Therefore, it is necessary to propose a tooling that can support the tire mold to facilitate through-hole processing, so as to avoid workers having to squat or bend over continuously during the processing. Utility Model Content

[0006] The purpose of this utility model is to provide an auxiliary tooling for through-hole processing of vent holes in tire molds in order to solve at least one of the above-mentioned problems. This solution solves the problem that workers need to squat or bend over continuously when processing through-holes in tire molds in the prior art. This solution raises the tire mold and can drive the tire mold to rotate. Thus, after placing the tire mold on the tooling during the through-hole processing, the worker can complete the through-hole processing of the vent holes on the tire mold without bending over or moving it.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] An auxiliary tooling for a vent hole in a tire mold includes an upper platform, a lower platform, and a rotating shaft;

[0009] The upper platform is movably connected to the lower platform via a rotating shaft;

[0010] The top surface of the upper platform is a hollow support plane used to support the tire mold;

[0011] The bottom surface of the lower platform is a bearing plane, used to be placed flat on a horizontal surface;

[0012] The rotating shaft is connected to the center of the upper platform.

[0013] Preferably, the upper platform is tilted.

[0014] Preferably, the angle between the upper platform and the rotation axis is 80-90°.

[0015] Preferably, the supporting plane includes a shaft connection portion connecting the rotation shaft, an outer edge portion forming a polygon, and a support rod connecting the shaft connection portion and the outer edge portion.

[0016] Preferably, the outer edge portion forms a regular polygon, the shaft connection portion is located at the centroid of the regular polygon, and the support rod is on the line connecting the vertex of the regular polygon and the centroid of the regular polygon.

[0017] Preferably, the upper platform is further provided with a boss at the center of its top surface for positioning the tire mold.

[0018] Preferably, the lower platform includes a bearing plane and a sleeve; the bearing plane has the same structure as the support plane, and the sleeve is connected to the center of the bearing plane for fitting a rotating shaft.

[0019] Preferably, the lower platform further includes a reinforcing support; the reinforcing support is connected between the bearing plane and the sleeve.

[0020] Preferably, the reinforced support is arranged symmetrically at the center.

[0021] Preferably, the top of the sleeve is provided with a columnar platform.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] This auxiliary tooling can first raise the tire mold, so that workers can perform through-hole processing without bending over; furthermore, the upper platform of the auxiliary tooling can rotate around the rotation axis, so that after processing one section, the worker can rotate the tire mold without moving it.

[0024] There is a small angle between the upper platform and the rotating shaft, which allows the target vent to be processed to be placed at the lowest point when processing the vent. This prevents the vent from rotating due to the force applied by the worker during processing, thus avoiding damage to the mold due to external movement.

[0025] The bosses set on the upper platform further position and limit the tire mold, ensuring that the tire mold is reliably placed on the auxiliary tooling and will not fall or shift during processing. Attached Figure Description

[0028] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] An auxiliary tooling for through holes in tire mold vents, such as Figure 1 As shown, it includes an upper platform 1, a lower platform 2, and a rotation axis;

[0031] The upper platform 1 is movably connected to the lower platform 2 via a rotating shaft;

[0032] The top surface of the upper platform 1 is a hollow support plane used to support the tire mold;

[0033] The bottom surface of the lower platform 2 is a bearing plane, used to be placed flat on a horizontal surface;

[0034] The rotating shaft is connected to the center of the upper platform 1.

[0035] More specifically, in this embodiment:

[0036] The supporting plane of the upper platform 1 includes: a shaft connecting part 11 connected to the connecting shaft, an outer edge part 12 forming a polygon, and a support rod 13 connecting the shaft connecting part 11 and the outer edge part 12. Based on this, the supporting plane is a hollow structure. The shaft connecting part 11 is a circular plane, the outer edge part 12 is a regular polygon structure, and the support rod 13 is respectively arranged on the line connecting the vertex of the regular polygon and the centroid of the regular polygon. The structural design of this supporting plane can effectively support the tire mold and further provide hollow space for the tire rubber material blocked in the vent hole to fall down.

[0037] In some other embodiments, a small included angle between 0-10°, such as 1°, 5°, or 10°, can be designed between the upper platform 1 and the rotating shaft. Thus, when the lower platform 2 is placed horizontally, the supporting plane of the upper platform 1 has a certain included angle with the horizontal plane, that is, the supporting plane has a lowest point. At this time, placing the vent to be processed at the lowest point can reduce the occurrence of the tire mold being pushed to move due to the force applied during the venting process, thereby reducing the possibility of damage to the tire mold.

[0038] In some other embodiments, a boss can be provided at the center of the support plane of the upper platform 1 to position and limit the tire mold, thereby preventing the tire mold from shifting during the through hole processing.

[0039] The lower platform 2 includes a bearing plane and a sleeve 21 for fitting a rotating shaft, thus the lower plane has an overall "⊥" structure. The bearing plane adopts the same structure as the support plane, and the sleeve 21 is located at the center of the bearing plane. In addition, to further enhance the overall strength of this auxiliary tooling, multiple reinforcing supports 22 are provided in the lower platform 2; the reinforcing supports 22 are connected from the edge of the bearing plane to the top of the sleeve 21, forming a diagonal bracing structure. Furthermore, in this embodiment, one end of the reinforcing support 22 is connected to the vertex of the regular polygon formed by the edge of the support plane, and six supports are arranged symmetrically at the center. In addition, a columnar platform is provided on the outer wall of the top of the sleeve 21 to thicken its top, and the other end of the reinforcing support 22 is connected to the outer wall of the columnar platform, which can effectively improve the structural strength of the connection.

[0040] In this auxiliary tooling, except for the rotating shaft and the sleeve 21 which are rotatably connected (a bearing can be installed in the sleeve 21 to rotate with the rotating shaft), all other parts can be directly welded and fixed.

[0041] In use, the tire mold is placed on the supporting plane of the upper platform 1. By rotating the upper platform 1, the vent hole to be processed can be quickly positioned, allowing the worker to process the vent without bending over. After processing the current vent hole, the upper platform 1 is rotated again to position the next vent hole to be processed. This way, the worker does not need to walk back and forth when processing vent holes in different locations. Due to the weight of the tire mold itself, it will not shift under normal operation once it is placed on this auxiliary fixture.

[0042] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
