A guide groove 36 is provided on the surface of the movable plate 1. A slide bar 35 is slidably connected inside the guide groove 36. A positioning rod 33 is threadedly connected inside the slide bar 35. A sliding mold 2 is sleeved on the surface of the positioning rod 33. A rack 34 is fixedly connected to one side of the slide bar 35. The rack 34 is slidably connected to the inside of the guide groove 36. The rack 34 is meshed with the surface of the rotating wheel 32. A drive assembly is provided on the surface of the movable plate 1.

[0024] Specifically, the drive assembly includes a first motor 31, which is fixedly connected to the surface of the movable plate 1. The drive end of the first motor 31 is fixedly connected to the surface of the rotating wheel 32. The first motor 31 can cooperate with the rotating wheel 32 to drive the rotating wheel 32 to rotate.

[0025] Specifically, a limiting device 4 is provided on the surface of the movable plate 1. The limiting device 4 includes a second motor 41, which is fixedly connected to the surface of the movable plate 1.

[0026] In this embodiment, the second motor 41 can cooperate with the movable plate 1 to fix the second motor 41.

[0027] In this embodiment: the drive end of the second motor 41 is fixedly connected to the transmission rod 42, and the movable plate 1 is slidably connected to the slider 47. The transmission rod 42 and the slider 47 are internally threadedly connected. The transmission rod 42 can cooperate with the second motor 41 to achieve the purpose of driving the transmission rod 42 to rotate.

[0028] Specifically, the movable plate 1 has a sliding connection to a pressing block 46, which is placed on the lower surface of the rack 34.

[0029] In this embodiment, the extrusion block 46 can cooperate with the movable plate 1 to guide the extrusion block 46 to slide.

[0030] Specifically, an anti-detachment block 45 is fixedly connected to the upper surface of the compression block 46, and a groove 44 is provided on the surface of the rack 34. The groove 44 is slidably connected to the surface of the anti-detachment block 45. The anti-detachment block 45 can cooperate with the compression block 46 and the groove 44 to achieve the purpose of restricting the rack 34.

[0031] Specifically, an adjusting bar 43 is rotatably connected between the extrusion block 46 and the slider 47, and the adjusting bar 43 is located on one side of the movable plate 1.

[0032] In this embodiment, the adjusting strip 43 can cooperate with the pressing block 46 and the slider 47 to adjust the sliding of the pressing block 46.

[0033] Working principle: By setting the adjustment device 3, when the operator needs to adjust the position of the positioning pin, the operator starts the first motor 31. The first motor 31 drives the rotating wheel 32, the rotating wheel 32 pushes the rack 34, the rack 34 pushes the slide bar 35, and the slide bar 35 is guided by the guide groove 36. The slide bar 35 drives the positioning rod 33 to move. When the positioning rod 33 slides to the designated position, the first motor 31 is turned off, and the limiting device 4 is activated. The limiting device 4 restricts the rack 34. The operator installs the sliding mold 2 on the movable plate 1, and the sliding mold 2 is fitted onto the positioning rod 33. By setting the adjustment device 3, the operator can effectively and conveniently adjust the position of the positioning pin, avoiding jamming when the threaded rod comes into contact with oil or debris. This reduces the risk of malfunction during the use of the fine-tuning device. Furthermore, by setting a limiting device 4, when the operator needs to limit the rack 34, the operator starts the second motor 41. The second motor 41 drives the transmission rod 42, which rotates and pushes the slider 47. The slider 47 pushes the adjusting strip 43, which in turn pushes the extrusion block 46. The extrusion block 46 slides inside the movable plate 1 and pushes the anti-detachment block 45, which inserts into the slide groove 44. The extrusion block 46 then abuts against the surface of the rack 34. The second motor 41 is then turned off. By setting the limiting device 4, the operator can effectively limit the rack 34, preventing it from becoming loose and thus improving the stability of the sliding mold 2.
