[0011] Preferably, an anti-slip pull sleeve is fixedly sleeved on the outer wall of one end of the pull hook, and the anti-slip pull sleeve is made of magnetic alloy.

[0012] Preferably, a rotating shaft is fixedly mounted on the top of the base, and the bottom of the flip block is rotatably sleeved on the outer wall of the rotating shaft.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model cooperates with the draw hook in the draw hook mechanism with the spring and the limit block, and under the action of the spring elastic force, the draw hook hook end can tighten the upper end of the face sleeve in the mold core cavity, and the anti-skid draw sleeve drives the draw hook and the flip block to flip. After flipping, the anti-skid draw sleeve is adsorbed and fitted on the magnet under the suction force of the magnet to prevent the draw hook from flipping, so that the draw hook hook end is lifted up to tighten the face sleeve, and the gas inside the face sleeve is discharged. Compared with the previous structure, this structure is easier to operate, avoids product scrapping due to wrinkles in the face sleeve, improves production efficiency, and reduces scrap rate.

[0021] A headrest mold spring hook structure, comprising a mold core 1, with hook mechanisms 2 for tightening a face cover installed on both sides of the mold core 1;

[0022] The hook mechanism 2 includes a base 21, which is detachably mounted on a side wall of the mold core 1, a magnet 22 is fixedly mounted inside the base 21, a flip block 23 is rotatably mounted on the top of the base 21, a hook 24 for tightening the facing sleeve is slidably inserted inside the flip block 23, the hook end of the hook 24 passes through the flip block 23 and extends into the mold cavity of the mold core 1, and the other end of the hook 24 passes through the flip block 23 and extends to the outside of the flip block 23.

[0023] The outer wall of the hook 24 is sleeved with a limit block 25, which is located inside the flip block 23 and is locked and fixed to the outer wall of the hook 24 by a locking screw, so that the position of the limit block 25 on the outer wall of the hook 24 can be adjusted by the locking screw.

[0024] The limit block 25 is matched with the interior of the flip block 23 , and the outer wall of the limit block 25 is slidably connected with the inner wall of the flip block 23 , so that the limit block 25 can slide inside the flip block 23 .

[0025] A spring 26 is fixedly installed on the inner wall of the flip block 23, one end of the spring 26 is fixedly connected to one side of the limit block 25, and the spring 26 is sleeved on the outer wall of the draw hook 24. Through the elastic force of the spring 26, the hook end of the draw hook 24 can tighten the inner surface sleeve of the mold core 1.

[0026] An anti-skid pull sleeve is fixedly sleeved on the outer wall of one end of the hook 24, and the anti-skid pull sleeve is set to be made of magnetic alloy, so that the anti-skid pull sleeve is adsorbed and attached to the magnet 22 under the suction force of the magnet 22 to prevent the hook 24 from turning over.

[0027] A rotating shaft is fixedly installed on the top of the base 21, and the bottom of the flip block 23 is rotatably sleeved on the outer wall of the rotating shaft, so that the flip block 23 can be flipped from the state of being in contact with the top of the base 21 through the cooperation of the rotating shaft.

[0028] Working principle: When the utility model is used, the hook 24 in the hook mechanism 2 cooperates with the spring 26 and the limit block 25. Under the action of the elastic force of the spring 26, the hook end of the hook 24 can tighten the upper end of the inner sleeve of the mold core 1, and the anti-slip pull sleeve drives the hook 24 and the flip block 23 to flip. After flipping, the anti-slip pull sleeve is adsorbed and attached to the magnet 22 under the suction force of the magnet 22 to prevent the hook 24 from flipping, so that the hook end of the hook 24 is lifted up to tighten the face sleeve. Compared with the previous structure, this structure is easier to operate, avoids product scrapping due to wrinkles in the face sleeve, improves production efficiency, and reduces scrap rate.
