Description

Technical Field

[0001] This utility model belongs to the field of tire vulcanization technology, specifically relating to a bracket for changing the movable block of a tire mold. Background Technology

[0002] Tire molds are key equipment used for vulcanizing and molding various types of tires, playing a crucial role in the tire production process. Tire molds can be categorized into several types depending on the tire product, including movable molds, two-part molds, tire tread molds, tire sidewall molds, tire base molds, and complete tire mold sets.

[0003] During the vulcanization and production of tires using tire molds, it is necessary to create patterns, text, or numbers on the tire tread. Therefore, various types of movable blocks are incorporated into the tire molds to assist in tire production and shaping. Currently, these movable blocks are typically designed as detachable structures, allowing for the selection and installation of appropriate blocks during the vulcanization production of tires of different specifications and types, thereby achieving the target design and requirements of the tire product.

[0004] However, in the existing technology, when replacing the movable parts of the tire mold, a gantry crane is used to lift the tire mold, and then the movable parts that need to be replaced are located, disassembled, and reinstalled. However, this process not only occupies the regular use of the gantry crane, but also requires workers to stand under or near the lifted tire mold to find and replace the movable parts, as well as to flip the tire mold, which poses a significant safety hazard.

[0005] Therefore, there is a need for a support that facilitates the replacement of tire mold blocks while ensuring safety during use. Utility Model Content

[0006] The purpose of this utility model is to provide a bracket for changing the movable parts of a tire mold in order to solve at least one of the above-mentioned problems. This solves the problems of the occupancy and safety of the gantry crane in the prior art when using a gantry crane to lift the tire mold for changing the movable parts. This solution realizes the movable support of the tire mold through the bracket, which not only facilitates the search and replacement of the movable parts, but also improves the safety of the replacement process.

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

[0008] A bracket for changing movable blocks in tire molds includes a support column, a support link, and a movable support component;

[0009] The support column includes an outer support column and an inner support column; at least three outer support columns are provided, and the outer support columns surround the inner support columns.

[0010] The support link is connected between the inner support column and the outer support column; each support link is provided with at least one movable support member;

[0011] The movable support components include bearing housings, rolling bearings, and omnidirectional balls; the bearing housings are fixedly installed on the surface of the support connecting rods, and the omnidirectional balls are installed inside the bearing housings via rolling bearings; each movable support component forms a support plane for supporting the tire mold.

[0012] Preferably, the support column includes three outer support columns and one inner support column, which form an equilateral triangle support structure; the outer support columns are located at the vertices of the equilateral triangle, and the inner support column is located at the centroid of the equilateral triangle.

[0013] Preferably, the movable support is located on a circle centered on the inner support column.

[0014] Preferably, several movable support members are arranged at intervals along the length of the support link.

[0015] Preferably, the movable support members are arranged at equal intervals.

[0016] Preferably, the outer support columns are further connected by reinforcing links; the reinforcing links are connected to the middle or lower part of the outer support columns.

[0017] Preferably, a tray is also provided between the outer support columns; the tray is connected to the middle or lower part of the outer support column.

[0018] Preferably, the inner support column is a round tube, and the inner support column is higher than the outer support column, for positioning in conjunction with the center hole of the tire mold.

[0019] Preferably, the rolling bearing is a bullseye bearing.

[0020] Preferably, the support is a rotationally symmetric structure.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] At least three movable support members surrounding the inner support column form a support plane for carrying the tire mold. Meanwhile, the rear movable support member employs a freely rotatable omnidirectional ball joint structure, allowing the tire mold to rotate freely as needed to locate the replacement lug after it is placed on the movable support member, making it convenient to use. Furthermore, during use, the inner support column passes through the central opening of the tire mold for positioning and limiting, ensuring its support effect and preventing the tire mold from shifting or falling during use, thus guaranteeing safety.

[0023] The structural design of the support frame provides multi-point symmetrical support for the tire mold, ensuring stable support.

[0024] The reinforcing links between the outer support columns can further improve the overall structural strength of the bracket to meet the needs of tire molds of different specifications.

[0025] A tray is also provided in the middle or lower part of the support, which can temporarily store tools for changing the live block and the replaced live block, to avoid the parts being piled up randomly. Attached Figure Description

[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0032] Example

[0033] A bracket for changing the movable block of a tire mold, such as Figure 1-4 As shown, it includes a support column, a support link 2, and a movable support member 3;

[0034] The support column includes an outer support column 11 and an inner support column 12; at least three outer support columns 11 are provided, and the outer support columns 11 are arranged around the inner support column 12.

[0035] The support link 2 is connected between the inner support column 12 and the outer support column 11; each support link 2 is provided with at least one movable support member 3;

[0036] The movable support 3 includes a bearing seat 31, a rolling bearing 32, and a universal ball 33; the bearing seat 31 is fixedly installed on the surface of the support connecting rod 2, and the universal ball 33 is installed inside the bearing seat 31 through the rolling bearing 32; each movable support 3 forms a support plane for supporting the tire mold.

[0037] More specifically, in this embodiment:

[0038] like Figure 1 , 2 As shown, the support column includes an outer support column 11 located at the three vertices of an equilateral triangle and an inner support column 12 located at the centroid of the equilateral triangle; the inner support column 12 is connected to each of the outer support columns 11 by a support link 2, and three movable support members 3 are evenly spaced on the upper surface of each support link 2, which are used to form a support plane for carrying the tire mold.

[0039] The bracket has a rotationally symmetrical structure. The movable support members 3 arranged around the inner support column 12 form a concentric arrangement with the inner support column 12 as the center. This provides uniform support force to the tire mold placed on it and can adapt to tire molds of different sizes. At the same time, both the inner support column 12 and the outer support column 11 are set higher than the movable support members 3, and the inner support column 12 is also set higher than the outer support column 11. Furthermore, the inner support column 12 is a circular tube that can be connected to the center hole of the tire mold. Thus, after the tire mold is placed on the bracket, it will be limited by the limiting position of the outer support column 11 and the positioning of the inner support column 12. Therefore, the tire mold can only rotate around the inner support column 12.

[0040] Active support component 3, such as Figure 3 , 4 As shown, the system includes a bearing housing 31, a rolling bearing 32, and a universal ball joint 33. The bearing housing 31 is fixedly mounted to the support connecting rod 2 by screws or rivets. The rolling bearing 32 is mounted on the bearing housing 31, and the universal ball joint 33 is mounted within the rolling bearing 32. Furthermore, the free rotation of the universal ball joint 33 allows the tire mold supported on it to rotate smoothly. Specifically, the rolling bearing 32 in this design is a bullseye bearing, which has excellent load-bearing and rotational capabilities, and can effectively handle different types of tire molds.

[0041] A reinforcing link 4 can be provided between adjacent outer support columns 11, located in the middle or lower part, to strengthen the overall structural support and thus adapt to the use of heavy tire molds; in addition, a tray can be fixedly welded at the middle or lower part of the outer support column 11 to temporarily place the tool for replacing the live block and the replaced live block.

[0042] The outer support column 11 can be made of square tubing, with a disc-shaped support base at its bottom, thus providing a larger support surface for more stable support. The support connecting rod 2 can also be made of square tubing and can be connected to the outer support column 11 and the inner support column 12 by welding. The specific dimensions of the bracket should be designed according to different requirements to meet the needs of the tire mold being supported.

[0043] When using this support, align the center hole of the tire mold with the inner support column 12, then insert the tire mold into the inner support column 12 and lower the tire mold onto the support plane formed by the movable support member 3. The worker can then use the universal ball joint 33 of the movable support member 3 to rotate the tire mold to find the loose piece to be replaced. During use, the design of the universal ball joint 33 allows for convenient and labor-saving rotation of the tire mold; simultaneously, because the tire mold is inserted into the inner support column 12, it will not shift or fall off during rotation, ensuring worker safety. Furthermore, the multi-arm support structure provides stable and reliable support for the tire mold placed on it, further preventing accidents.

[0044] The use of this bracket can eliminate the need for overhead cranes; at the same time, the positioning and limiting of the tire mold by the support column, as well as the rolling structure of the movable support 3, allow the tire mold to be quickly adjusted and the position of the movable block to be replaced to be found when placed on it, ensuring safety during use.

[0045] 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.
