When the gear 505 of the first servo motor 504 meshes with the gear ring 502, the gear ring 502 can rotate on the base 501, thereby realizing the rotation adjustment of the first tire mold 4.

[0030] The bracket 503 is arranged vertically on the gear ring 502, the gear ring 502 is arranged in a circular ring shape, the base 501 is arranged in a circular ring shape, the diameter of the base 501 is larger than the diameter of the gear ring 502, and the gear ring 502 and the base 501 are both located outside the first tire mold 4. The second servo motor 6 can be connected by the arrangement of the bracket 503, and the second servo motor 6 can rotate with the bracket 503 on the gear ring 502.

[0031] The output end of the second servo motor 6 is fixedly connected to a connecting seat 9, and a cross frame 10 is fixedly connected to the connecting seat 9. One end of the cross frame 10 is fixedly connected to a collar 8. The collar 8 is located at the outer periphery of the first tire mold 4. A pressure plate 7 is arranged above the collar 8. The pressure plate 7 is arranged in a circular ring shape as a whole, and the collar 8 is arranged in a circular ring shape as a whole. The pressure plate 7 and the collar 8 are arranged on the same axis. The inner diameter of the collar 8 is the same as the outer diameter of the first tire mold 4. The first tire mold 4 is placed at the center of the collar 8 and the pressure plate 7.

[0032] It needs to be further explained that a slide rod 16 is slidably connected to the collar 8, and the slide rod 16 is vertically arranged on the corresponding collar 8. The upper end of the slide rod 16 is fixedly connected to the corresponding pressure plate 7. A first spring 15 is sleeved on the slide rod 16, and the first spring 15 is located between the pressure plate 7 and the collar 8. One end of the first spring 15 is clamped and connected to the pressure plate 7, and the other end of the first spring 15 is clamped and connected to the collar 8.

[0033] Specifically, by arranging a slide rod 16 on the collar 8, the slide rod 16 can move on the collar 8. When the slide rod 16 is connected to the pressure plate 7, the pressure plate 7 will not be displaced in position, and the pressure plate 7 will be stable when it moves. The pressure plate 7 can be buffered by the setting of the first spring 15, and the pressure plate 7 will be reset by the first spring 15 after being not pushed.

[0034] It needs to be further explained that an outer cover 17 is fixedly connected to the inner ring surface of the collar 8, a rubber pad 18 is provided on the inner wall of the outer cover 17, an air port 19 is opened on the central axis position of the rubber pad 18 and the outer cover 17, the air port 19 and the air chamber 20 are interconnected, the air chamber 20 is located inside the collar 8, a sealing gasket 21 is slidably connected inside the air chamber 20, one end of the sealing gasket 21 is fixedly connected to a cross rod 22, and the input end of the cross rod 22 is fixedly connected to the pressing mechanism 11.

[0035] Specifically, when opening a hole in the first tire mold 4, the staff only needs to place the first tire mold 4 into the ring 8. The ring 8 and the rubber pad 18 can be tightly attached to the first tire mold 4. The width of the ring 8 and the pressure plate 7 is small. When the first tire mold 4 is turned over, it will not affect the opening of the opposite side. The ring 8 can be sleeved on the outer periphery of the first tire mold 4, thereby achieving connection with the first tire mold 4, and the rubber pad 18 on the ring 8 can be attached to the ring 8.

[0036] It needs to be further explained that a cylinder 14 is fixedly connected inside the machine tool 1, and the output end of the cylinder 14 is fixedly connected to the linkage frame 13. The linkage frame 13 is arranged in a cross shape as a whole. Each end of the linkage frame 13 is fixedly connected to a lifting rod 12. The lifting rod 12 is connected to the machine tool 1 through the base 501. The base 501 is fixedly connected to the lifting rod 12.

[0037] Specifically, the cylinder 14 can drive the linkage frame 13 to move up and down as a whole. The linkage frame 13 is connected to the base 501 through the lifting rod 12. The base 501 can be driven by the cylinder 14 to move up and down, thereby adjusting the position between the first tire mold 4 and the machine tool 1, so as to adjust it to a position that satisfies the flipping of the first tire mold 4.

[0038] In the implementation, by arranging the cylinder 14 inside the machine tool 1, the cylinder 14 can realize the up and down driving of the lifting rod 12 by driving the linkage frame 13 up and down. When the lifting rod 12 moves up and down, it can drive the connected base 501 to move up and down. When the base 501 moves up and down, it can drive the second servo motor 6 to move up and down as a whole through the bracket 503. The collar 8 and the pressing plate 7 connected to the second servo motor 6 can move up and down. The first tire mold 4 fixed in the collar 8 can be driven to move up, so as to approach the drill bit of the movable seat 3. After the first tire mold 4 is driven to rise, the second tire mold 4 can be driven to move up and down. A turning space can be left between a tire mold 4 and the machine tool 1, and the ring 8 can be driven by the second servo motor 6 to rotate, so as to achieve angle adjustment. The base 501 is connected to a gear ring 502, and the gear ring 502 is arranged on a bracket 503. The first servo motor 504 on the base 501 is engaged with the gear ring 502 through a gear 505. The first servo motor 504 can drive the gear ring 502 to rotate as a whole, and finally achieve the adjustment of the first tire mold 4 in multiple directions, so that the opening of the mold is more convenient, thereby improving the production efficiency of the tire mold.

[0039] It needs to be further explained that the pressing mechanism 11 includes a third servo motor 113, to which a screw 114 is fixedly connected, and a threaded seat 112 is threadedly connected on the screw 114. A limiting rod 111 is inserted at the edge of the threaded seat 112, and one end of the limiting rod 111 is fixedly connected to the third servo motor 113. An extrusion head 115 is provided on the threaded seat 112, and the extrusion head 115 is slidably connected to a fixed frame 117. The fixed frame 117 is fixedly set on the side surface of the pressure plate 7, and an inclined frame 119 is provided on the fixed frame 117. The inclined frame 119 is provided with a lower head 110, and the inclined frame 119 is inserted in the socket 116. The socket 116 is opened on the socket 118, and the socket 118 is connected to the cross rod 22.

[0040] The third servo motor 113 is fixedly connected to the connecting seat 9, the screw 114 on the third servo motor 113 is parallel to the cross frame 10, and the limit rod 111 and the extrusion head 115 are respectively located on both sides of the screw 114. Through the connection between the cross frame 10 and the collar 8, the second servo motor 6 can drive the collar 8 to flip as a whole.

[0041] The input end of the extrusion head 115 is arranged in a triangular shape as a whole, and the hypotenuse of the extrusion head 115 is slidably connected to the fixing frame 117, and the fixing frame 117 is horizontally fixedly connected to the pressing plate 7. When the extrusion head 115 pushes the fixing frame 117, the fixing frame 117 moves along the inclined surface of the extrusion head 115, thereby realizing downward movement.

[0042] The hypotenuse of the oblique frame 119 is slidably connected to one end of the socket 116, and the lower head 110 connected to the oblique frame 119 is located below the socket 118. The lower head 110 is arranged in a triangular shape as a whole, and the hypotenuse of the lower head 110 is slidably connected to the socket 118. Through the arrangement of the lower head 110, the lower head 110 can push the socket 118 in the reverse direction, thereby realizing the replenishment of gas, thereby realizing the shedding of the first tire mold 4.

[0043] Specifically, the threaded seat 112 can be restricted by the limit rod 111. When the threaded seat 112 moves, it will not rotate with the screw rod 114. When the threaded seat 112 moves, it can drive the extrusion head 115 to push down the fixed frame 117. After the fixed frame 117 is pushed down, the pressure plate 7 will move downward as a whole. The pressure plate 7 can drive all the fixed frames 117 to move downward, thereby pushing the socket 118 to move horizontally.

[0044] During implementation, after the first tire mold 4 is placed, the third servo motor 113 is started, and the third servo motor 113 will drive the extrusion head 115 to press down the fixing frame 117. After the fixing frame 117 is pressed down, the sealing pad 21 will move to extract the air between the rubber pad 18 and the first tire mold 4, thereby forming a negative pressure, and the first tire mold 4 can be fixed. Then, the cylinder 14 is adjusted as needed to raise the position of the second servo motor 6, and then the first servo motor 504 is adjusted to rotate the first tire mold 4. Finally, the second servo motor 6 is adjusted to flip the first tire mold 4, thereby realizing adjustment at multiple angles, thereby improving processing efficiency and reducing the labor intensity of staff.

[0045] When the first spring 15 pushes the pressure plate 7 to reset, the lower push head 110 of the fixed frame 117 will move toward the position of the socket 118, thereby pushing the socket 118 in the reverse direction, so that the socket 118 drives the cross rod 22 to push the sealing gasket 21, and the gas can enter between the rubber pad 18 and the first tire mold 4 again, thereby achieving the falling off of the first tire mold 4.

[0046] In the implementation, by arranging a cross frame 10 on the collar 8, the cross frame 10 is connected to the connecting seat 9 of the second servo motor 6, the second servo motor 6 can drive the collar 8 to rotate as a whole, the connecting seat 9 is provided with a third servo motor 113, the third servo motor 113 is provided with a screw 114, the screw 114 is threadedly connected to the threaded seat 112, the third servo motor 113 can control the movement of the threaded seat 112, the threaded seat 112 is provided with an extrusion head 115, the extrusion head 115 can move toward the fixed frame 117 of the pressing plate 7, when the extrusion head 115 moves to the position of the pressing plate 7, the pressing plate 7 can be moved downward by extrusion, when the pressing plate 7 moves downward, the inclined frame 119 will be driven downward by the fixed frame 117, and the inclined frame 119 will be moved by the insertion The extrusion of the seat 118 causes the socket 118 to move horizontally. When the socket 118 moves horizontally, it can drive the cross rod 22 to move horizontally. The cross rod 22 will drive the sealing pad 21 to move along the air chamber 20. At this time, the gas between the rubber pad 18 and the first tire mold 4 will be extracted, thereby forming a negative pressure, and the rubber pad 18 will be adsorbed on the first tire mold 4 as a whole. The rubber pad 18 is installed in the outer cover 17. The rubber pad 18 will not soften and fall off during adsorption. The outer cover 17 is set on the ring 8. The ring 8 cooperates with the rubber pad 18 to fix the first tire mold 4. When the second servo motor 6 drives the ring 8 to rotate, the first tire mold 4 can be driven, thereby realizing the adjustment of multiple angles of the first tire mold 4, thereby meeting the hole opening requirements.
