[0032] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] like Figures 1-7 As shown, the present invention provides a jig for processing the side plate of a tire mold, comprising a base 1, a clamping mechanism 2, a tightening mechanism 3, a driving mechanism 4, and a positioning mechanism 5.

[0034] The base 1 is used for overall fixation and installation of various components. It is circular in shape and has multiple bottom grooves 101 that are evenly distributed around the center line of the base 1. The bottom grooves 101 are used to accommodate the drive mechanism 4.

[0035] The clamping mechanism 2 is used to clamp the side plate of the tire mold to prevent the side plate from moving during processing. The clamping mechanism 2 includes a base plate 21, a gripper 22, a winch seat 23, and a connecting rod 24. The base plate 21 is fixedly mounted on the base 1, and the winch seat 23 is fixedly mounted on the base plate 21. One end of the connecting rod 24 is rotatably mounted on the winch seat 23. The base plate 21 has a groove for accommodating the gripper 22. The gripper 22 is slidably mounted in the groove and is rotatably mounted on the end of the connecting rod 24 away from the winch seat 23. By rotating the connecting rod 24 and cooperating with the rotation of the gripper 22 itself, the edge of the tire mold side plate is clamped, thereby fixing the side plate. Multiple clamping mechanisms 2 are provided on the base 1, and the multiple clamping mechanisms 2 are evenly distributed around the center line of the base 1, increasing the distribution range of the gripper 22 and making the side plate more firmly and stably fixed.

[0036] The clamping mechanism 3 is used to clamp the side plate of the tire mold, improving the firmness and stability of the tire mold side plate during fixing. The clamping mechanism 3 includes a top block 31, a support platform 32, and a pressure plate 33. The support platform 32 is fixedly mounted on the base plate 21. A sliding groove 301 is provided through the support platform 32, and the top block 31 is slidably mounted in the sliding groove 301. The lifting and lowering of the top block 31 is achieved by sliding. When the top block 31 rises, it can pass through the pressure plate 33 and abut against the side plate. When the top block 31 falls, it can retract into the sliding groove 301 and will not bulge outward. The plate 33 is fixedly installed on the top of the support platform 32, and the pressure plate 33 has a through groove 302. The top block 31 includes a top block body 311, a tightening part 312 and an anti-slip groove 313. The tightening part 312 is installed on the top of the top block body 311, and the tightening part 312 can pass through the pressure plate 33 through the through groove 302. After passing through the pressure plate 33, the tightening part 312 abuts against the side plate and tightens the side plate. Therefore, the side plate is simultaneously subjected to the clamping force of the claw 22 and the tightening force of the top block 31, which further improves the firmness and stability of the side plate fixation.

[0037] To prevent the side panels from slipping due to external forces during processing, such as Figure 6 As shown, the top of the main body 311 of the top block is provided with an anti-slip groove 313. By opening the anti-slip groove 313, the friction between the anti-slip groove and the side plate is increased, making the side plate less likely to move, thereby preventing the side plate from slipping.

[0038] The drive mechanism 4 is used to drive the gripper 22 to rotate and the top block 31 to rise and fall. The drive mechanism 4 includes a drive cylinder 41 and a push block 42. The drive cylinder 41 is fixedly installed at the bottom of the base plate 21. The output end of the drive cylinder 41 is rotatably connected to the bottom of the gripper 22. When the output end of the drive cylinder 41 extends, the bottom of the gripper 22 moves outward. Under the action of the connecting rod 24, the top of the gripper 22 descends, thereby clamping and pressing the edge of the tire mold side plate. The push block 42 is fixedly installed on the output end of the drive cylinder 41 and is slidably connected to the top block 31. The top side of the push block 42 is inclined. The distance between the top side of the push block 42 and the base plate 21 gradually increases from top to bottom. When the output end of the drive cylinder 41 extends, the push block 42 pushes the top block 31 to rise under the action of the inclined surface, thereby achieving the clamping and fixing of the side plate.

[0039] The positioning mechanism 5 is used for the installation and positioning of the tire mold side plate. The positioning mechanism 5 includes a slide rail 51, a pad 52, an adjusting seat 53, and a stop block 54. The slide rail 51 is slidably fixed on the base 1, and its extension length can be adjusted by sliding to accommodate tire mold side plates of different sizes. The pad 52 is fixed on the base 1 and is located at both ends of the slide rail 51. The slide rail 51 and the pad 52 are slidably connected. The pad 52 guides the sliding of the slide rail 51 and supports the tire mold side plate. The adjusting seat 53 is fixedly mounted on the slide rail 51. Both contact surfaces of the adjusting seat 53 and the slide rail 51 are provided with serrated grooves to increase the friction between the adjusting seat 53 and the slide rail 51 and prevent slippage after the adjusting seat 53 is fixed. The abutment block 54 is fixedly mounted on the adjusting seat 53. The abutment block 54 is used to position the tire mold side plate by abutting against the tire mold side plate, which is convenient for installation. The position of the abutment block 54 can be adjusted by adjusting the adjusting seat 53, so as to be suitable for positioning tire mold side plates of different sizes.

[0040] To improve the positioning accuracy during the installation of tire mold side plates, such as Figure 1 As shown, multiple positioning mechanisms 5 are provided on the base 1, and the multiple positioning mechanisms 5 are evenly distributed around the center line of the base 1. The positioning mechanisms 5 are staggered with the clamping mechanism 2. When the tire mold side plate is placed on the fixture, its edge abuts against the abutment block 54. By using the positioning of multiple abutment blocks 54, the tire mold side plate is made concentric with the base 1, thereby ensuring the processing accuracy.

[0041] The method of using the fixture for processing the side plate of a tire mold according to this utility model is as follows:

[0042] Before installation, first adjust the installation position of the abutment block 54 according to the size of the tire mold side plate so that the distance between the abutment block 54 and the center of the base 1 is consistent with the radius of the tire mold side plate. Then adjust the installation position of the clamping mechanism 2. When installing the tire mold side plate, the edge of the tire mold side plate is pressed against the abutment block 54. The positioning effect of the abutment block 54 makes the tire mold side plate concentric with the base 1. Then the output end of the drive cylinder 41 extends and the drive cylinder 41 pushes the gripper 22 to rotate, clamping the edge of the tire mold side plate. At the same time, the push block 42 pushes the top block 31 to rise under the action of the inclined plane. The top block 31 is used to press the tire mold side plate. The tire mold side plate is fixed under the action of clamping force and pressing force.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
