[0024] When working, a clamping device of a split tire mold in the above technology needs to rotate the bidirectional screw first, and then start the drive motor to complete the clamping operation of the tire mold. The operation process will be more cumbersome. Through the structural design of the clamping mechanism, the function of facilitating the clamping of the aviation tire molding mold placed on the placement table 20 is realized. When the aviation tire molding mold placed on the placement table 20 is to be clamped and fixed, the servo motor 47 is first used to drive the screw rod 22 inside the cavity 21 to rotate, and the moving blocks 23 threadedly connected on both sides of the screw rod 22 will move toward each other, thereby driving the connecting block 24 and the clamping plate 25 to move closer to each other until the clamping plate 25 approaches the mold and clamps the mold. In the process of horizontal movement of the clamping plate 25, the fixing rod 37 will be in the long groove 3 8 slides and passes through the long slot 38 track, so that when the clamping plate 25 gradually approaches the mold, the position of the fixing rod 37 will gradually move downward. Since the bottom end of the connecting plate 29 is connected to the tension spring 27, the connecting plate 29 will be pulled downward by the tension spring 27, thereby driving the connecting rod 30 and the slider 33 fixed on the top of the connecting rod 30 to move downward. At this time, the clamping plate 34 fixed to the slider 33 will move downward, thereby completing the clamping of the top part of the mold until the clamping operation of the aircraft tire molding mold is completed. The threads on the left and right sides of the screw rod 22 have opposite rotation directions, the rear end of the movable slot 28 is connected to the outside world, and the bottom end of the connecting plate 29 is inserted into the inside of the slot 26 to ensure that the connecting plate 29 can stably move in the movable slot 28.

[0025] Furthermore, two groups of clamping blocks 40 are welded and fixed on the bottom end of the connecting block 24, and the clamping blocks 40 are slidably connected to the inner wall of the clamping slot 41, and the clamping slot 41 is provided on the inner wall of the cavity 21;

[0026] During operation, through the structural design of the block 40 and the slot 41, when the moving block 23 moves on the screw rod 22, the two groups of blocks 40 fixed on the connecting block 24 will also slide in the slot 41 and support the connecting block 24 through the contact between the block 40 and the slot 41, so that the connecting block 24 can move more stably. At the same time, the contact between the block 40 and the inner wall of the slot 41 can also reduce the pressure on the screw rod 22.

[0027] Furthermore, a pad 35 is glued and fixed on the clamping plate 25, and an arc groove is formed on the pad 35;

[0030] During operation, the moving wheel 43 rotates on the circular groove 42 to realize the function of rotating the placement table 20 on the processing table 1, so as to adjust the position and direction of the mold placed on the placement table 20.

[0031] Furthermore, the middle portion of the screw rod 22 is sleeved inside the support block 44, and the support block 44 is welded and fixed to the inner wall of the cavity 21;

[0032] During operation, the support block 44 is fixedly connected to the inner wall of the cavity 21, and the screw rod 22 is rotationally connected to the support block 44. The support block 44 provides support for the screw rod 22 so that the screw rod 22 will not shake easily during rotation.

[0033] Furthermore, two sets of positioning blocks 45 are welded and fixed on the bottom end of the placement table 20, and multiple sets of pin holes 46 are opened on the top end of the processing table 1, and pins are inserted into the positioning blocks 45;

[0035] Working principle: A clamping device for a segmented tire mold in the prior art needs to rotate the bidirectional screw first and then start the drive motor to complete the clamping operation of the tire mold. The operation process is relatively cumbersome. A clamping device for a molding mold for aircraft tire processing in this case realizes the function of facilitating the clamping of the aircraft tire molding mold placed on the placement table 20 through the structural design of the clamping mechanism. When the aircraft tire molding mold placed on the placement table 20 is to be clamped and fixed, the servo motor 47 is first used to drive the screw rod 22 inside the cavity 21 to rotate, and the moving blocks 23 threadedly connected on both sides of the screw rod 22 will move toward each other, thereby driving the connecting block 24 and the clamping plate 25 to move closer to each other until the clamping plate 25 approaches the mold and clamps the mold. During the horizontal movement of the clamping plate 25 The fixing rod 37 will slide in the long groove 38 and through the design of the long groove 38 track, the position of the fixing rod 37 will gradually move downward as the clamping plate 25 gradually approaches the mold. Since a tension spring 27 is connected to the bottom end of the connecting plate 29, the connecting plate 29 will be pulled downward by the tension spring 27, thereby driving the connecting rod 30 and the slider 33 fixed on the top of the connecting rod 30 to move downward. At this time, the clamping plate 34 fixed to the slider 33 will move downward, thereby completing the clamping of the top part of the mold until the clamping operation of the aircraft tire molding mold is completed. The threads on the left and right sides of the screw rod 22 have opposite rotation directions, the rear end of the movable groove 28 is connected to the outside world, and the bottom end of the connecting plate 29 is inserted into the inside of the slot 26 to ensure that the connecting plate 29 can stably move in the movable groove 28.
