[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0028] like Figure 1-7 As shown, a zipper device with a locking function and a production device thereof, comprising a slider 1, the slider 1 comprising an upper plate 11 and a lower plate 12, a locking mechanism 2 being arranged between the two, the locking mechanism 2 comprising a rotating support core 21 rotatably connected to the upper plate 11, a cone angle 211 being arranged at a first end of the rotating support core 21, the rotating support core 21 being driven to flip so that the cone angle 211 faces the tooth chain;

[0029] The casting mold also includes an upper mold 42 and a lower mold 41, which are clamped to form a casting space, in which a rotating support core 21 is cast, and a flip block 40 is rotatably connected to the lower mold 41, and the flip block 40 is driven to flip and push the rotating support core 21.

[0030] Specifically, the slider 1 includes an upper plate 11 and a lower plate 12, between which a locking mechanism 2 is arranged. The locking mechanism 2 includes a rotating support core 21 rotatably connected to the upper plate 11. The first end of the rotating support core 21 (with Figure 2 For reference, the first end is the right end) is provided with a cone angle 211. When the slider 1 is pulled, the rotating support core 21 is driven to flip so that the cone angle 211 faces the chain, and then the sliding slider 1 pushes the chain along the cone angle 211 to separate the meshed chain. When not in use, the rotating support core 21 is driven to flip so that the cone angle 211 is away from the chain. At this time, the slider 1 cannot separate the chain when sliding to play a locking role;

[0031] The casting mold includes an upper mold 42 and a lower mold 41, which are clamped to form a casting space, in which a rotating support core 21 is cast, and a flip block 40 is rotatably connected to the lower mold 41; during casting, the upper mold 42 and the lower mold 41 are closed to form a casting space with a clamp, and then molten steel is poured in the casting space. After waiting for it to cool, the flip block 40 is flipped to make the flip block 40 push the rotating support core 21 in the casting space to facilitate demoulding.

[0032] Furthermore, in the above embodiment, the structure for driving the rotating core 21 to be driven to flip can be a magnetic block fixed on the rotating core 21 and a magnetic block slidably connected to the upper plate 11. When there is no need to pull, the magnetic block on the upper plate 11 and the magnetic block on the rotating core 21 fit together, and the two magnetic blocks are attracted to each other, so that the rotating core 21 flips and the cone angle 21 is away from the tooth chain. When the tooth chain needs to be unlocked and separated, it is only necessary to separate the magnetic block on the upper plate 11 and the magnetic block on the rotating core 21, so that the magnetic block on the rotating core 21 is attracted to the lower plate 12 for unlocking; it can also be an arc paddle set on the rotating core 21, and symmetrical rubber blocks are set on the upper plate 11. The arc paddle plate is located between the symmetrical rubber blocks. When in use, the arc paddle plate is pushed to flip the rotating core 21 to achieve the cone angle 21 away from or close to the tooth chain; or it can be any structure known to those skilled in the art.

[0033] In the above technical solution, a rotating support core 21 is utilized. When there is no need to pull the slider 1, the rotating support core 21 will be driven to flip so that the cone angle 211 is away from the tooth chain. At this time, the fabric cannot separate the tooth chain when pulling the tooth chain, so as to play a locking role and prevent external force from separating the two pieces of fabric. When the slider 1 is pulled, the rotating support core 21 will be driven to flip so that the cone angle 211 is directed toward the tooth chain to separate them along the cone angle 211. At this time, it can play a separation role and can have a locking function without affecting normal use.

[0034] As the best embodiment provided by the present invention, a pull nose 111 is provided on the upper plate 11, and an elastic hook strip 22 is provided on the rotating support core 21.

When in use, when the pull handle 3 is held by hand to pull the slider 1, the connecting buckle 31 will pull the elastic hook strip 22 to extend so that the rotating support core 21 is turned over so that the cone angle 211 is toward the tooth chain. At this time, the sliding slider 1 will push the tooth chain along the cone angle 211 to separate the meshed tooth chain. When not in use, the pull handle 3 is released, and at this time the elastic hook strip 22 rebounds to pull the rotating support core 21 to turn over so that the cone angle 211 is away from the tooth chain. At this time, the slider 1 cannot separate the tooth chain when sliding to play a locking role;

[0035] During pouring, the upper mold 42 and the lower mold 41 are closed to form a casting space with a hoop, and then molten steel is poured in the casting space. After waiting for it to cool, the flip block 40 is flipped to push the flip block 40 out of the rotating support core 21 in the casting space. The flipping and pushing mode can push out the slender elastic hook strip 22, which can prevent the elastic hook strip 22 from breaking during demolding.

[0037] During pouring, the upper mold 42 and the lower mold 41 are closed to form a casting space with a hoop, and then molten steel is poured in the casting space. After waiting for it to cool, the flip block 40 is flipped to push the flip block 40 out of the rotating support core 21 in the casting space. The flipping and pushing mode can push out the slender elastic hook strip 22, which can prevent the elastic hook strip 22 from breaking during demolding.

At this time, the slider 1 will push the tooth chain along the cone angle 211 to separate the meshed tooth chain. When not in use, release the pull handle 3, and at this time the elastic hook strip 22 rebounds to pull the rotating support core 21 to flip so that the cone angle 211 is away from the tooth chain. At this time, the slider 1 cannot separate the tooth chain when sliding to play a locking role;

[0039] During casting, the upper mold 42 and the lower mold 41 are closed to form a casting space with a hoop, and then the fixed frame 43 is clamped on the flip block 40. At this time, the limit plate 402 fits the inner wall of the fixed frame 43. Because the flip block 40 is rotatable, the limit plate 402 can play a locking role when it fits the fixed frame 43. Then, molten steel is poured in the casting space, and after waiting for it to cool, the flip block 40 is flipped to push the flip block 40 out of the rotating support core 21 in the casting space. The flipping and pushing-out mode can push out the slender elastic hook strip 22, which can prevent the elastic hook strip 22 from breaking during demolding.

At this time, the slider 1 will push the tooth chain along the cone angle 211 to separate the meshed tooth chain. When not in use, release the pull handle 3, and at this time the elastic hook strip 22 rebounds to pull the rotating support core 21 to flip so that the cone angle 211 is away from the tooth chain. At this time, the slider 1 cannot separate the tooth chain when sliding to play a locking role;

[0041] During casting, the upper mold 42 and the lower mold 41 are closed so that the first casting groove 422 and the second casting groove overlap to form a casting space with a hoop, and then the fixed frame 43 is clamped on the flip block 40. At this time, the limit plate 402 fits the inner wall of the fixed frame 43. Because the flip block 40 is rotatable, the limit plate 402 can play a locking role when it fits the fixed frame 43.
