Description

Technical Field

[0001] The utility model relates to the technical field of tire molds, and particularly relates to a tire mold with an adjustable limit fixing structure. Background Art

[0002] Tire molds are tools or equipment used for manufacturing tires. Their design and manufacture need to consider factors such as tire size, tire tread pattern, rubber material, etc., and it is necessary to ensure that the quality of the produced tires meets the standards. A tire mold with an adjustable limit fixing structure is a tire manufacturing mold that can adjust the tire size and shape through an adjustable limit device. This structure can adapt to the production of tires of different specifications by changing the position and length of the limit device, improving the versatility and production efficiency of the mold.

[0003] During the tire manufacturing process, tire molds will frequently come into contact with substances such as rubber, vulcanizing agent, mold release agent, and various additives. These substances gradually deposit and adhere on the mold surface, forming stubborn dirt and residues, seriously affecting the production quality of tires and the service life of the molds. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the background art, and a tire mold with an adjustable limit fixing structure is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A tire mold with an adjustable limit fixing structure includes a platform. Two first cylinders are fixedly installed on the top of the platform. The telescopic ends of the first cylinders are fixedly connected to an outer mold. Four support rods are fixedly connected to the bottom of the platform. The bottom of the support rods is fixedly connected to a base. A rotating shaft is rotatably connected to the top of the base. A motor is fixedly installed at the bottom of the platform. The motor is rotationally connected to the rotating shaft through a gear transmission mechanism.

[0007] Preferably, the gear transmission mechanism includes a first gear fixedly connected to the top of the rotating shaft. The output end of the motor is fixedly connected to a second gear. The first gear meshes with the second gear.

[0008] Preferably, a second cylinder is fixedly installed on the top of the first gear. The telescopic end of the second cylinder is welded to an inner mold.

[0009] Preferably, two support blocks are fixedly connected to the top of the platform. A third cylinder is fixedly installed on the top of the support blocks. The telescopic end of the third cylinder is fixedly connected to a brush.

[0010] Preferably, two vertical rods are fixedly connected to the top of the platform, a ventilation duct is fixedly connected to the top of the vertical rods, and a nozzle is fixedly connected to one end of the ventilation duct away from the vertical rods.

[0011] Preferably, the two outer molds, the two brushes, and the two nozzles are all symmetrical.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By setting the nozzle, the brush, and the motor, the present utility model can spray high-pressure water flow or cleaning liquid, effectively impacting the dirt on the surface of the mold to loosen it; the brush can further brush off the loosened dirt and residual substances. The two work together, greatly improving the cleaning degree of the mold, ensuring that the surface of the mold is clean without impurities, thereby guaranteeing the production quality of the tire. Compared with some powerful cleaning methods such as sandblasting, the combination of the nozzle and the brush is relatively gentle, which can reduce the wear and damage to the surface of the mold while effectively cleaning, and prolong the service life of the mold.

[0014] 2. By setting the cylinder and the second cylinder, the present utility model can quickly demold, significantly shortening the tire production cycle, enabling the mold to complete a production cycle in a shorter time, thereby increasing the tire output per unit time. The fast and stable demolding process can reduce the stress and damage suffered by the tire during demolding, reducing the possibility of defects such as flaws, deformation, or tearing of the tire, and improving the product quality.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Referring to Figures 1-3 , a tire mold with an adjustable limit fixing structure includes a platform 1. The platform 1 is rectangular with a circular opening in the middle. Two first cylinders 2 are fixedly installed on the top of the platform 1. The telescopic end of the first cylinder 2 is fixedly connected to an outer mold 3. The outer mold 3 is semi-circular with a groove in the middle. The outer mold 3 does not contact the platform 1. Four support rods 4 are fixedly connected to the bottom of the platform 1. The four support rods 4 are at the edge of the bottom of the platform 1.

[0021] The bottom of the support rod 4 is fixedly connected to a base 17. The base 17 is rectangular. The support rods 4 are at the four corners of the base 17. A rotating shaft 5 is rotatably connected to the top of the base 17. The rotating shaft 5 is in the middle of the top of the base 17. A motor 8 is fixedly installed on the bottom of the platform 1. The motor 8 is rotationally connected to the rotating shaft 5 through a gear transmission mechanism.

The first gear 6 meshes with the second gear 7. A second cylinder 9 is fixedly installed on the top of the first gear 6. The telescopic end of the second cylinder 9 is welded to an inner mold 10. The inner mold 10 is cylindrical in shape and has an annular groove in the middle of the side wall.

[0023] Two support blocks 11 are fixedly connected to the top of the platform 1. A third cylinder 12 is fixedly installed on the top of the support block 11.
