One side of the carrier block is ensured to maintain contact with the fixed block only by a spring. The position of the carrier block is easily moved due to vibration or accidental contact, resulting in poor fixing effect. The structural design of the engagement mechanism makes it possible to better fix the sealing block 21 and facilitate the release of the sealing block 21. The connecting rod 24 slides inside the cavity 26, and the block 25 fixed on the connecting rod 24 is engaged with the slot 23 and passes through the slot 23. The engagement and abutment between the card block 25 ensure that the position of the sealing block 21 is fixed, and the connecting rod 24 is arranged inside the cavity 26, which is not easily disturbed by the outside world, and the fixation of the sealing block 21 is more stable. When the sealing block 21 is to be released, it is only necessary to press the top block 27 downward, and the bottom end part of the top block 27 will abut against the connecting rod 24 and push the connecting rod 24 to move to both sides. During the movement of the connecting rod 24, the card block 25 will be driven away from the card slot 23 until it is separated from the card slot 23, and the abutment and engagement between the card block 25 and the card slot 23 will be released.

[0027] Furthermore, the top of the top block 27 is not kept level with the top of the mold body 1, and a slider 32 is welded and fixed on the top of the mold body 1;

[0028] During operation, the top of the top block 27 is lower than the mold body 1 , and a slider 32 is fixed to the mold body 1 to provide protection for the top block 27 and reduce the possibility of the top block 27 moving due to accidental contact.

[0029] Furthermore, two sets of slide grooves 31 are formed on the inner wall of the cavity 26, and a slider 32 is slidably connected inside the slide groove 31, and the slider 32 is welded and fixed to the bottom end of the connecting rod 24;

[0033] Furthermore, the cross-sections of the top rod 28 and the bottom end of the sliding sleeve 33 are both T-shaped, and the inner wall of the fixed sleeve 35 does not contact the valve stem 22;

[0034] During operation, the structural design of the push rod 28 and the bottom end of the sliding sleeve 33 prevents the push rod 28 from sliding out of the movable groove 30, thereby ensuring the normal operation of the push rod 28. Similarly, the structure of the sliding sleeve 33 can ensure that the sliding sleeve 33 will not separate from the fixed sleeve 35.

[0035] Working principle: In the prior art, an exhaust structure of a tire mold is fixed by the engagement of a carrier block with a fixed block. One side of the carrier block is ensured to maintain contact with the fixed block only by a spring. The position of the carrier block is easily moved due to vibration or accidental contact, resulting in poor fixing effect. In this case, an exhaust structure of an aviation tire molding mold is designed with a locking mechanism to achieve a better fixing effect on the sealing block 21 and facilitate the release of the sealing block 21. The connecting rod 24 slides inside the cavity 26, and the block 25 fixed on the connecting rod 24 and the card slot 2 The position of the sealing block 21 is fixed by the engagement and contact between the card slot 23 and the card block 25, and the connecting rod 24 is arranged inside the cavity 26, which is not easily disturbed by the outside world, and the fixing of the sealing block 21 is more stable. When the fixing of the sealing block 21 is to be released, it is only necessary to press the top block 27 downward, and the bottom end of the top block 27 will contact with the connecting rod 24 and push the connecting rod 24 to move to both sides. During the movement of the connecting rod 24, the card block 25 will be driven away from the card slot 23 until it is separated from the card slot 23, and the engagement and contact between the card block 25 and the card slot 23 will be released.
