Description

Technical Field

[0001] The present application relates to the field of tires, and more particularly, to a forming tool for preventing lack of tread rubber. Background Art

[0002] A tire is a circular ring-shaped elastic rubber product that is mounted on various vehicles or machines and rolls on the ground. It is usually installed on a metal rim, can support the vehicle body, buffer external impacts, achieve contact with the road surface, and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperatures during driving. Therefore, they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.

[0003] During the production process of tires, due to the poor fluidity of the tread rubber during the vulcanization process of the tires, as Figure 1 shown, there is no object on the surface of the common tire forming gripper that can increase the fluidity of the tread rubber at present, resulting in the lack of tread rubber on the tire tread. This not only makes the appearance of the tire unaesthetic, but also reduces the service life of the tire. Summary of the Utility Model

[0004] To make up for the above deficiencies, the present application provides a forming tool for preventing lack of tread rubber, aiming to improve the problem that the fluidity of the tread rubber is poor during the vulcanization process of the tire, resulting in the lack of tread rubber on the tire tread, which not only makes the appearance of the tire unaesthetic, but also reduces the service life of the tire.

[0005] An embodiment of the present application provides a forming tool for preventing lack of tread rubber, including a gripper.

[0006] The gripper is arc-shaped, and a plurality of needles that can increase the fluidity of the tread are detachably arranged on the inner side of the gripper.

[0007] In a specific implementation manner, one end of each needle close to the gripper is fixedly connected with a mounting seat, and each mounting seat is detachably connected with the inner side of the gripper.

[0008] In a specific implementation manner, a plurality of mounting grooves are formed on the inner side of the gripper, and each mounting seat is detachably installed inside the corresponding mounting groove.

[0009] In a specific implementation manner, a connecting bolt is screwed on the outer side of the gripper, and the connecting bolt penetrates through the gripper and is screwed with the mounting seat.

[0010] In a specific embodiment, a countersunk hole is provided at the nut of each of the connecting bolts on the outer side of the grasping clip.

[0011] In a specific embodiment, a first threaded groove mating with the connecting bolt is further provided on the grasping clip, a second threaded groove is provided on the mounting seat, and the first threaded groove and the second threaded groove communicate with each other.

[0012] In a specific embodiment, a connecting seat is further fixedly connected to the outer side of the grasping clip.

[0013] In a specific embodiment, the mounting seat is elastically arranged and can completely fill the mounting groove.

[0014] Beneficial effects: When the grasping clip grasps the tread rubber of the tire, it can change the fluidity of the tread rubber. By providing a plurality of sharp needles on the grasping clip, it can not only improve the fluidity of the tire tread, thereby improving the lack of rubber in the tire tread, but also keep the tire more fixed during the grasping process and not easily deformed. Through the detachable connection between the sharp needle and the grasping clip, when some sharp needles are bent and deformed, the deformed sharp needles can be replaced, so that it is not necessary to replace the entire grasping clip, improving the service life of the grasping clip and thus reducing the production cost.

[0021] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0022] Please refer to Figures 1-4 , the present application provides a forming tool for preventing lack of tread rubber, including a gripping clip 1.

[0023] Please refer to Figure 2 , Figure 3 and Figure 4 , the gripping clip 1 is arc-shaped, and a plurality of needles 2 that can increase the fluidity of the tread are detachably arranged on the inner side of the gripping clip 1. Among them, when the gripping clip 1 grips the tread rubber of the tire, the fluidity of the tread rubber can be changed. By arranging a plurality of needles 2 on the gripping clip 1, not only can the fluidity of the tire tread be improved, thereby improving the lack of tread rubber of the tire, but also the tire can be more fixed during the gripping process and is not prone to deformation. Through the detachable connection between the needle 2 and the gripping clip 1, when some needles 2 are bent and deformed, the deformed needles 2 can be replaced, so that it is not necessary to replace the entire gripping clip 1, improving the service life of the gripping clip 1 and thus reducing the production cost.

[0024] In this embodiment, one end of each needle 2 close to the gripping clip 1 is fixedly connected with a mounting seat 4, and each mounting seat 4 is detachably connected to the inner side of the gripping clip 1. A plurality of mounting grooves 6 are formed in the inner side of the gripping clip 1, and each mounting seat 4 is detachably installed inside the corresponding mounting groove 6. A connecting bolt 5 is screwed on the outer side of the gripping clip 1, and the connecting bolt 5 penetrates through the gripping clip 1 and is screwed with the mounting seat 4. A counterbore 7 is formed at the nut of each connecting bolt 5 on the outer side of the gripping clip 1. The gripping clip 1 is also provided with a first thread groove that cooperates with the connecting bolt 5, and the mounting seat 4 is provided with a second thread groove, and the first thread groove and the second thread groove communicate with each other. The mounting seat 4 is elastically arranged and can completely fill the mounting groove 6. Among them, when installing the needle 2, the mounting seat 4 is pressed into the mounting groove 6, and then the screw rod of the connecting bolt 5 is screwed into the first thread groove and the second thread groove in sequence from the outer side of the gripping clip 1 to realize the installation of the needle 2. When disassembling, the connecting bolt 5 is screwed out from the second thread groove and the first thread groove in sequence.

[0025] When specifically setting, a connecting seat 3 is also fixedly connected to the outer side of the gripping clip 1. Among them, the gripping clip 1 is installed on the molding machine equipment through the connecting seat 3, and the needle 2 is directly installed on the gripping clip 1, and the existing molding equipment can still be used normally to realize the gripping of the tire.

[0026] The working principle of the forming tool for preventing lack of tread rubber:

[0027] When the gripping clip 1 grips the tire tread rubber, it can change the fluidity of the tread rubber. By providing a plurality of sharp needles 2 on the gripping clip 1, it can not only improve the fluidity of the tire tread, thereby improving the lack of rubber in the tire tread, but also keep the tire more fixed during the gripping process and not easily deformed. Through the detachable connection between the sharp needle 2 and the gripping clip 1, when some sharp needles 2 are bent and deformed, the deformed sharp needles 2 can be replaced, so that it is not necessary to replace the entire gripping clip 1, improving the service life of the gripping clip 1 and thus reducing the production cost.
