Description

Technical Field

[0001] The utility model belongs to the technical field of mold processing, in particular to a high-strength positioning mechanism for tire mold processing. Background Art

[0002] Tire molds are molds used for vulcanization molding of various types of tires. Tire mold classification: flexible mold, composed of a tread ring, a mold sleeve and upper and lower side plates. In order to ensure stability during processing, the tire mold needs to be limited by a positioning mechanism to ensure processing efficiency. When in use, the existing positioning mechanism drives multiple limiting components to move toward each other through a driving component, so that multiple limiting components are close to each other to position the tire mold. Although the positioning effect can be achieved, it is not convenient to adjust the tire mold when it is placed on the installation box for processing. Manual assistance is required to adjust the tire mold, which increases the workload of the staff and is time-consuming and labor-intensive.

[0003] After searching, the Chinese patent document (authorization announcement number CN219706145U) shows that the utility model relates to a high-strength positioning mechanism for tire molds, including a mounting box, the top surface of which is provided with four movable slots, the bottom surface of which is fixedly provided with a servo motor protective cover, the top surface of which is fixedly provided with a fixing plate, the top surface of which is rotatably provided with a tire mold, and the interior of the mounting box is provided with a driving assembly for driving a fixing device to fix the tire mold, and the driving assembly includes a main bevel gear and a servo motor shaft. Although the patent can achieve the positioning effect, it is not convenient to adjust the tire mold when it is placed on the mounting box for processing, and manual assistance is required to adjust the tire mold, thereby increasing the work intensity of the staff and being more time-consuming and labor-intensive.

[0011] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0012] The high-strength positioning mechanism for tire mold processing benefits from the design of the auxiliary components and the stepper motor. By starting the forward and reverse motors to drive the first screw to rotate, the rotation of the first screw can drive the two adjustment rods to move toward each other to position the tire mold. By starting the driving motor of the auxiliary component to drive the second screw to rotate, the rotation of the second screw drives the two movable blocks to be linked. The adjustment of the movable block can drive the lifting plate at the top of the movable rod to adjust the height, thereby lifting the tire mold. Starting the stepper motor can drive the positioned tire mold to rotate, so that the device can not only achieve the positioning effect, but also facilitate adjustment, making the adjustment operation easier and more labor-saving.

[0023] Examples, such as Figures 1 to 3 As shown, two rectangular mounting plates 4 are installed at the top of the auxiliary component 3, and a first screw rod 13 is installed between the two mounting plates 4. The first screw rod 13 is a two-stage design, which can drive the two adjustment rods 5 to move toward each other. A forward and reverse motor 14 providing adjustment power for the first screw rod 13 is installed on the side of the mounting plate 4. The mounting plate 4 is specifically installed on the lifting plate 32. The outer periphery of the first screw rod 13 is threadedly connected to two L-shaped adjustment rods 5.

The design of the limit grooves can adjust the adjustment rods 5. Limiting is performed, and the length of the adjusting rod 5 can meet the adjustment requirements. The opposite surfaces of the two limit plates 7 are equipped with rotating shafts, and a positioning plate 9 for high-strength limiting of the tire mold is installed between the two rotating shafts. The shape of the positioning plate 9 is preferably an arc shape, and the arc shape can better fit the tire mold. The specific shape depends on the actual situation. The fixed end of the stepper motor 6 is installed on the side of the limit plate 7, and the driving end of the stepper motor 6 passes through the limit plate 7 and is connected to the driving shaft 11. Gears 12 are installed on the sides of the driving shaft 11 and the rotating shaft, and the two gears 12 are meshed and connected.

[0024] A circular mounting groove is installed at the top of the workbench 1, and a placement table 8 for holding the tire mold is installed on the inner side of the mounting groove.

[0027] How it works

[0028] The high-strength positioning mechanism for tire mold processing, when in use, is placed on a placement table 8 to be processed, and the first screw rod 13 is driven to rotate by starting the forward and reverse motors 14. The rotation of the first screw rod 13 can drive the two adjustment rods 5 to move toward each other, thereby driving the two positioning plates 9 to adjust, and the tire mold is positioned. After the positioning is completed, the processing operation can be carried out, and the servo motor 10 is started according to the actual situation to drive the placement table 8 to rotate, so that the tire mold can be adjusted. When rotation adjustment is required, the drive motor 31 is started to drive the second screw rod 33 to rotate, and the rotation of the second screw rod 33 drives the two movable blocks 35 to be linked. The adjustment of the movable block 35 can drive the lifting plate 32 at the top of the movable rod 34 to adjust the height, thereby lifting the tire mold. Starting the stepper motor 6 can drive the positioned tire mold to rotate, that is, the adjustment effect is achieved.
