[0031] As Figures 1-5 shown, the present utility model provides a punching device for a tire mold, which has a bottom plate 1. Among them, an adjusting ring 11 is fixedly installed at the left end of the bottom plate 1 through two columns 10. Six slideways 2 are fixedly installed on the adjusting ring 11 at equal circumferential intervals. Slide blocks 21 are slidably connected to the slideways 2. An adjusting groove 22 is provided through the slide blocks 21. Abutting plates 23 for supporting the tire mold are fixedly installed at the mutually approaching ends of the slide blocks 21. Anti-slip pads 231 are fixedly installed on the inner surfaces of the abutting plates 23.

[0032] The fixed end of a lifting cylinder B4 is fixedly installed at the right end of the bottom plate 1. The movable end of the lifting cylinder B4 extends upward and an end part thereof is fixedly installed with a cross beam 41. A connecting shaft A42 is rotatably connected to one side of the cross beam 41 close to the adjusting ring 11. A driven wheel 43 is fixedly connected to the connecting shaft A42. A punching knife A51 for punching the tire mold is slidably connected to the driven wheel 43.

[0033] Optionally, in the above technical solution, the fixed end of a lifting cylinder A24 is fixedly installed on the bottom plate 1. The movable end of the lifting cylinder A24 extends upward and an end part thereof is fixedly installed on the bottom slide block 21.

[0034] Optionally, in the above technical solution, a chute 3 is provided on the adjusting ring 11 between two adjacent chutes 2. A sliding column 31 is slidably connected in each chute 3, and an adjusting rod 32 is fixedly installed on each sliding column 31.

[0035] Optionally, in the above technical solution, the adjusting rod 32 includes an upper cross bar 33 and a lower cross bar 34. One end of the upper cross bar 33 is fixedly connected to the top of one end of the lower cross bar 34. The upper cross bars 33 and the lower cross bars 34 of two adjacent adjusting rods 32 are slidably connected in an adjusting groove 22.

[0036] Optionally, in the above technical solution, a connecting shaft B44 is also rotatably connected to the cross beam 41. A driving wheel 45 is fixedly connected to the connecting shaft B44. A driving motor 46 is fixedly installed on one side of the cross beam 41 away from the driving wheel 45. The output shaft of the driving motor 46 is fixedly connected to the connecting shaft B44.

[0037] Optionally, in the above technical solution, the movable end of a telescopic cylinder C52 is fixedly installed on the punching knife A51. The fixed end of the telescopic cylinder C52 extends towards the middle of the driven wheel 43 and is fixedly installed on the driven wheel 43.

[0038] Among them, the six adjusting rods 32 form a hexagon, which is convenient for driving the six sliding blocks 21 to move simultaneously;

[0039] Among them, after the tire mold is clamped, its middle part is not blocked, and the center of it can be punched;

[0040] Among them, an auxiliary telescopic cylinder is fixedly installed between the punching knife A51 and the driven wheel 43, which is convenient for punching.

[0041] During use, place the tire mold at the inner ring opening of the adjusting ring 11. Start the lifting cylinder A24 to move its movable end upward, driving the bottom sliding block 21 fixedly connected thereto to move upward along the chute 2. The upper cross bars 33 and the lower cross bars 34 of two adjacent adjusting rods 32 slidably connected in the adjusting groove 22 of this sliding block 21 approach each other in this adjusting groove 22. At the same time, the sliding columns 31 of the above two adjacent adjusting rods 32 slide towards the inner ring opening of the adjusting ring 11 in the chute 3;

[0042] Since one adjusting rod 32 is slidably connected to the adjacent adjusting rod 32 in the adjusting groove 22, when the bottom sliding block 21 drives the adjusting rod 32 in its adjusting groove 22 to move inward, the remaining adjusting rods 32 slide in the chute 3 through the sliding columns 31 and drive the sliding of the adjusting rods 32 through the adjusting groove 22, so that the six sliding blocks 21 on the adjusting ring 11 can move synchronously, and the tire mold is clamped in the middle of the adjusting ring 11 through the abutting plate 23;

[0043] After the tire mold is clamped, adjust the height of the driven wheel 43 according to the position at the center of the tire mold. Start the lifting cylinder B4 to move its movable end upward until the driven wheel 43 is concentric with the tire mold. At this time, the distance between the punching knife A51 and the center of the connecting shaft B44 (i.e., the center of the tire mold) can be adjusted through the telescopic cylinder C52 to punch the tire mold. After punching a hole, start the driving motor 46 to drive the driving wheel 45 to rotate through the connecting shaft B44, and drive the meshing-connected driven wheel 43 to rotate, so that the punching knife A51 rotates along the circumference of the tire mold, and multiple circumferential hole positions of the tire mold can be processed.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
