Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire mold processing and clamping technology, and in particular to a tire mold engraving fixture. Background Technology
[0002] Tire molds are used for vulcanizing and molding various types of tires. They are key equipment in tire production and are widely used in the production of tires for automobiles, construction machinery, bicycles, motorcycles, and airplanes. The functions of tire molds include vulcanization and molding. The vulcanization process is the process of turning raw rubber into quenched rubber, so that the elasticity, strength, and oxidation resistance of the tire meet the requirements. Molding is the process of forming the tire's personalized tread pattern, design, lettering, and other appearance features according to the shape of the mold.
[0003] A radial tire mold tread engraving machine with publication number CN221137356U is disclosed. This patent uses a clamping plate in the clamping mechanism to place and clamp the tire mold to be engraved. During clamping, the clamping plate can be moved to different positions through the provided moving groove. After the movement, it can be effectively restricted by the return spring installed on the baffle. At the same time, it is driven by a second drive motor to improve the engraving efficiency.
[0004] In their daily work, the inventors discovered that the aforementioned radial tire mold pattern engraving machine relies on a clamping plate and springs to clamp and fix the tire mold. However, the springs are passive force-applying components rather than active force-applying components. During the engraving process, the tire mold will vibrate, which will cause the position of the clamping plate to change, thereby reducing the clamping stability of the clamping plate on the tire mold. Utility Model Content

Detailed Implementation
[0023] Example 1, as Figure 1-4 As shown, a tire mold engraving fixture includes a support platform 1, a support column 4 and a support plate 5 mounted on the top of the support platform 1, a tire mold body 6 placed on the surface of the support plate 5, and a support device 2 that limits and fixes the tire mold body 6 to the surface of the support plate 5.
[0024] Reference Figure 1-3 As shown, in this embodiment: the support device 2 includes two upright plates 21 fixedly mounted on the surface of the support platform 1. A threaded rod 22 and a rotating wheel 23 fitted on the surface are rotatably connected between the two upright plates 21. The threads on the surface of the threaded rod 22 are opposite threads centered on the rotating wheel 23. The support device 2 also includes a sliding rod 24 fixed between the two upright plates 21. Two movable plates 25 are threadedly connected to the surface of the threaded rod 22. The threaded rod 22 drives the movable plates 25 to slide on the outer wall of the sliding rod 24. The support device 2 also includes two inserts 26, one of which... One insert 26 is fixedly connected to the surface of the movable plate 25, and an arc plate 27 is fixedly installed on the bottom surface of the other insert 26. A U-shaped rod 28 is slidably inserted between the two inserts 26. The movable plate 25 and the arc plate 27 are fixed to the insert 26 by the U-shaped rod 28, so that the two arc plates 27 can support and limit the inside of the tire mold body 6, making it easy to support the tire mold body 6 and avoid deformation of the tire mold body 6 during carving, which would lead to inaccurate carving and thus improve the carving quality of the tire mold body 6.
[0025] Reference Figure 3-4As shown in this embodiment: the outer wall surface of the insert 26 is provided with a fixing device 3 to limit the U-shaped rod 28 inside the insert 26. The fixing device 3 includes an extension rod 31 fixedly installed on the outer wall surface of the insert 26 and a movable plate 32 that slides on the outer wall. A limiting rod 33 is fixedly installed on the surface of the movable plate 32. A plurality of limiting holes 34 matching the limiting rod 33 are evenly opened on the outer wall surface of the U-shaped rod 28. A circular plate 35 is fixedly installed on the end surface of the extension rod 31 away from the insert 26. A spring 36 is fixedly installed between the circular plate 35 and the movable plate 32.
[0026] Working principle: When using this device, first place the tire mold body 6 on the surface of the support plate 5. After placement, rotate the wheel 23. The rotation of the wheel 23 drives the threaded rod 22 to rotate. Since the threads on the surface of the threaded rod 22 are opposite to each other with the wheel 23 as the center, when the wheel 23 drives the threaded rod 22 to rotate, the two movable plates 25 connected by the threads on its surface will move away from each other on the surface of the slide rod 24. The movement of the two movable plates 25 away from each other on the surface of the slide rod 24 drives the insert 26 and the U-shaped rod 28 to move away from each other, ultimately causing the two arc plates 27 to move away from each other. The movement of the two arc plates 27 away from each other provides support and limitation for the interior of the tire mold body 6, making it easier to support the tire mold body 6 and avoid deformation of the tire mold body 6 during carving, which would lead to inaccurate carving. This improves the carving quality of the tire mold body 6. When it is necessary to adjust the thickness of the tire mold body 6... When adjusting the position of the U-shaped rod 28 inside the insert 26, first slide the movable plate 32 so that the movable plate 32 moves on the surface of the extension rod 31. The movement of the movable plate 32 on the surface of the extension rod 31 will compress the spring 36, causing the spring 36 to be compressed. At the same time, the movement of the movable plate 32 on the surface of the extension rod 31 will also drive the limiting rod 33 to move. The movement of the limiting rod 33 will cause it to move out of the limiting hole 34. The separation of the limiting rod 33 and the limiting hole 34 will cause the U-shaped rod 28 to lose its limit inside the insert 26. At this time, the U-shaped rod 28 can be pulled upward. When the U-shaped rod 28 moves to the appropriate position, release the movable plate 32. The rebound force of the spring 36 will cause the limiting rod 33 to re-insert into the corresponding limiting hole 34, thereby fixing the position of the U-shaped rod 28 at this time. Through the cooperation of the above structure, the position of the U-shaped rod 28 can be adjusted, thereby avoiding the tire mold body 6 being too thick and blocking the movement of the U-shaped rod 28, causing the support device 2 to fail to support and limit the tire mold body 6.
