[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-3As shown, this utility model provides a demolding device for a thick sheet vacuum forming machine, including a base frame 1. A vacuum forming mold 4 is fixedly mounted on the upper surface of the base frame 1. Multiple opening mechanisms 3 are provided on the outer side of the vacuum forming mold 4. An ejection mechanism 2 is provided below the opening mechanisms 3. One side of the ejection mechanism 2 is fixedly connected to one side of the base frame 1. The ejection mechanism 2 includes an ejection frame 20. One side of the ejection frame 20 is fixedly connected to the base frame 1. A moving plate 24 is slidably mounted on the inner side of the ejection frame 20. An ejection plate 23 is fixedly mounted on the upper surface of the moving plate 24. A protective pad 22 is fixedly mounted on the upper surface of the ejection plate 23. A threaded rod 28 is fixedly mounted on the lower surface of the moving plate 24. A rotating cylinder 25 and a rotating ring 27 are threadedly sleeved on the outer side of the threaded rod 28. The upper surface of the rotating ring 27 is fixedly connected to the lower end of the rotating cylinder 25. The outer side of 7 is rotatably connected to the lower surface of the ejector frame 20. Through the ejection mechanism 2, the operator first rotates the rotating cylinder 25 manually or with a tool. Since the rotating cylinder 25 is threadedly engaged with the threaded rod 28, and the rotating ring 27 rotatably connects the rotating cylinder 25 to the ejector frame 20, the rotation action is converted into the vertical movement of the threaded rod 28 and the moving plate 24. As the moving plate 24 slides smoothly in the moving groove 21 of the ejector frame 20, the ejection plate 23 and the protective pad 22 fixed on it gradually rise until the ejection plate 23 contacts the molded product and ejects it from the vacuum mold 4. The setting of the protective pad 22 effectively prevents damage to the product during the ejection process. The entire ejection process is stable and controllable. By adjusting the degree of rotation of the rotating cylinder 25, the demolding requirements of products with different thicknesses can be flexibly adapted.

[0018] The upper surface of the ejector frame 20 is provided with a moving groove 21, the inner side of the moving groove 21 is slidably attached to the outer side of the moving plate 24, the lower surface of the ejector frame 20 is provided with a rotating groove 29, the inner side of the rotating groove 29 is rotatably attached to the outer side of the rotating ring 27, and the outer side of the rotating cylinder 25 is provided with multiple anti-slip textures 26 distributed in a ring. The protective pad 22 effectively prevents damage to the product during the ejection process.

[0019] The opening mechanism 3 includes a disassembly block 30 and a locking block 35. One side of the disassembly block 30 is attached to one side of the locking block 35. Multiple fixing openings 39 arranged in a rectangular array are provided on one side of the disassembly block 30. Multiple locking openings 37 are provided on the outer side of the vacuum forming mold 4, and these openings are attached to the disassembly block 30 and the locking block 35. A slider 31 is slidably mounted on one side of both the disassembly block 30 and the locking block 35. Multiple fixing slots 34 arranged in a rectangular array are provided on one side of the slider 31, and these slots are fixedly engaged with the fixing openings 39. A pull hook 32 is fixedly mounted on the inner side of the slider 31. During use, the operator first pulls the slider 31 using the pull hook 32. Guided by the slide groove 38, the slider 31 moves along the disassembly block 30... As the slider 31 moves, the fixing slot 34 on it gradually separates from the fixing port 39 on the disassembly block 30. At the same time, the disassembly block 30 can be removed, and the slider 31 and the locking block 35 can be released from the locking opening 37 of the blister mold 4. At this time, the side opening of the blister mold 4 is opened, providing sufficient space for the ejection action of the ejection mechanism 2. After demolding, the operator can reverse the operation to reset the slider 31, so that the locking block 35 can be locked back onto the blister mold 4. At the same time, the lower end of the pull hook 32 can be locked with the hook 33 on the base frame 1, thus completing the closure of the opening mechanism 3. The whole opening process is simple and quick, effectively improving the demolding efficiency.

[0020] The disassembly block 30 and the engaging block 35 are provided with a sliding groove 38 on one side. The inner side of the sliding groove 38 is slidably attached to the slider 31. The engaging block 35 has two positioning holes 36 on one side. The positioning holes 36 are engaged with one side of the slider 31. The outer side of the base frame 1 has multiple hook holes 33. The hook holes 33 are engaged with the lower end of the pull hook 32. The lower end of the pull hook 32 can engage with the hook holes 33 on the base frame 1 to complete the closing of the opening mechanism 3.

[0021] Working principle: Through the ejection mechanism 2, the operator first rotates the rotating cylinder 25 manually or with a tool. Since the rotating cylinder 25 is threadedly engaged with the threaded rod 28, and the rotating ring 27 rotates the rotating cylinder 25 to the ejection frame 20, the rotation action is converted into the vertical movement of the threaded rod 28 and the moving plate 24. As the moving plate 24 slides smoothly in the moving groove 21 of the ejection frame 20, the ejection plate 23 and the protective pad 22 fixed on it gradually rise until the ejection plate 23 contacts the molded product and ejects it from the vacuum mold 4. The protective pad 22 effectively prevents damage to the product during the ejection process. The entire ejection process is stable and controllable. By adjusting the rotation degree of the rotating cylinder 25, the demolding requirements of products with different thicknesses can be flexibly adapted.

[0022] When using the opening mechanism 3, the operator first pulls the slider 31 with the hook 32. Guided by the slide groove 38, the slider 31 slides along the side of the disassembly block 30 and the locking block 35. As the slider 31 moves, the fixing slot 34 on it gradually separates from the fixing port 39 on the disassembly block 30. At the same time, the disassembly block 30 can be removed, and the locking block 35 can be released from the locking opening 37 of the vacuum forming mold 4. At this time, the side opening of the vacuum forming mold 4 is opened, providing sufficient space for the ejection action of the ejection mechanism 2. After demolding, the operator can reverse the operation to reset the slider 31, so that the locking block 35 can be re-locked onto the vacuum forming mold 4. At the same time, the lower end of the hook 32 can engage with the hook 33 on the base frame 1, thus completing the closure of the opening mechanism 3. The whole opening process is simple and quick, effectively improving the demolding efficiency.
