[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] A flipping device for a hook mold, such as Figures 1-5 As shown, the device includes a flipping mechanism and a conveying mechanism. The flipping mechanism includes two symmetrically spaced supports 1. Each support 1 is slidably connected to a mounting base 2 via a driving component. A vertically arranged stand 3 is fixedly connected to the top of the mounting base 2. A connecting base 4 is installed on the inner side wall of the stand 3. A horizontally arranged connecting shaft 5 is rotatably connected to the side of the connecting base 4 away from the stand 3. A vertically arranged clamping plate 6 is fixedly connected to the end of the connecting shaft 5. A flipping drive device for driving the clamping plate 6 to rotate is fixedly connected to the top of the connecting base 4. The clamping plate 6 is rotated by the flipping drive device.

[0021] The conveying mechanism includes a traveling trolley 7 located between two supports 1. Four corners of the bottom of the traveling trolley 7 are rotatably connected to traveling wheels 8, which are rolled onto a track 9. The track 9 is fixedly connected to the ground between the two supports 1. A horizontally positioned loading plate 10 is mounted on the top of the traveling trolley 7. At least one traveling wheel 8 is a drive wheel, rotating under external force to move the traveling trolley 7. In use, the mold to be flipped is placed on the loading plate 10. The traveling trolley 7 is started, moving the mold along the track 9 until it reaches between the two supports 1 and stops. The drive unit is then activated, causing the two mounting seats 2 to move closer together. This, in turn, causes the upright seat 3 and connecting seat 4 to move closer together, bringing the two clamping plates 6 closer together until the inner walls of both clamping plates 6 abut against the hook mold. The drive unit is then deactivated, and the flipping drive device is activated, causing the clamping plates 6 to rotate, thus flipping the hook mold between the two clamping plates 6. The clamping plate facilitates the clamping of the hook mold, and the rotating drive device drives the clamping plate to rotate, thereby realizing the rotation of the lifting mold. This avoids workers having to manually push the hook mold, reducing the workload of workers and reducing safety hazards during the rotation of the hook mold.

[0022] In another embodiment, the driving component includes a horizontally arranged movable cylinder 11, the fixed end of which is fixedly connected to the top of the support 1, and the piston rod end of the movable cylinder 11 is fixedly connected to the mounting base 2. In use, the piston rod end of the movable cylinder 11 extends, bringing the two clamping plates 6 closer together; conversely, the piston rod end of the movable cylinder 11 retracts, moving the two clamping plates 6 away from each other.

[0023] In another embodiment, the connecting seat 4 is a hollow structure, slidably connected to the outer wall of the stand 3. A lifting motor 12 is fixedly connected to the outer wall of the connecting seat 4. A horizontally arranged rotating shaft 13 is driven to the output shaft of the lifting motor 12. The rotating shaft 13 passes through the connecting seat 4 and is rotatably connected to the connecting seat 4. A gear 14 is fixedly connected to the rotating shaft 13. The gear 14 is located in the cavity of the connecting seat 4. A rack 15 that meshes with the gear 14 is fixedly connected to the stand 3 along its height direction. In use, the lifting motor 12 is driven, and the output shaft of the lifting motor 12 drives the rotating shaft 13 to rotate, thereby realizing the rotation of the gear 14. This causes the gear 14 to drive the connecting seat 4 to move along the direction of the rack 15, thus realizing the vertical movement of the connecting seat 4. This allows the vertical position of the clamping plate 6 to be adjusted, making it easier for the clamping plate 6 to approach the mold on the loading plate 10. This makes the device adaptable to hook molds of different heights, while also ensuring the contact area between the clamping plate 6 and the hook mold, improving the stability of the clamping.

[0024] In another embodiment, the flipping drive device includes a drive motor 16, which is fixedly connected to the top of the connecting base 4. A drive gear 17 is driven onto the output shaft of the drive motor 16. A horizontally arranged connecting shaft 5 is rotatably connected to the side of the connecting base 4 away from the upright base 3. The connecting shaft 5 is fixedly connected to a clamping plate 6, which is connected to the connecting base 4 via the connecting shaft 5. A driven gear 18, meshing with the drive gear 17, is fixedly connected to the connecting shaft 5. In use, the drive motor 16 is started, and its output shaft drives the drive gear 17 to rotate. The drive gear 17 drives the driven gear 18 to rotate, which in turn drives the rotating shaft 13 to rotate. This, in turn, causes the clamping plate 6 to rotate, thus flipping the hook mold held between the two clamping plates 6.

[0025] In another embodiment, a horizontally arranged suction plate 19 is fixedly connected to the top of the clamping plate 6 on the side away from the connecting seat 4. An suction element is fixedly connected to the bottom of the suction plate 19. The suction element can be a vacuum suction cup or a magnetic suction cup, and it is located in the bottom groove of the suction plate 19 and extends below the suction plate 19. With the suction plate 19 and the suction element, on the one hand, when clamping the hook mold, the bottom of the suction plate 19 abuts against the top of the upper mold of the hook mold, and the suction element adsorbs the hook mold, which improves the stability of the device in clamping the hook mold; on the other hand, during and after the flipping process, the suction plate 19 reduces the risk of the hook mold falling off, which improves the safety of operation.

[0026] In another embodiment, at least two lifting cylinders 20 are fixedly connected to the traveling trolley 7. The fixed end of the lifting cylinder 20 is fixedly connected to the top of the traveling trolley 7, and the piston rod end of the lifting cylinder 20 is fixedly connected to the bottom of the loading plate 10. The lifting cylinders 20 facilitate the adjustment of the height of the loading plate 10, which makes the connection between the tilting mechanism and the conveying mechanism faster and more accurate, and improves the convenience of operation.

[0027] In another embodiment, grooves 21 are provided on both sides of the support 3, and the side wall of the connecting seat 4 is slidably connected within the grooves 21. This arrangement improves the stability of the sliding between the connecting seat 4 and the support 3. Furthermore, a fixing plate 22 is fixedly connected to the outer side wall of the connecting seat 4 away from the clamping plate 6. The fixing plate 22 is detachably fixed to the support 3 by bolts 24. The support 3 has multiple threaded holes 23 along its height direction that are compatible with the bolts 24. When the size of the hook mold to be flipped by this device is fixed, the connecting seat 4 can be fixed to the support 3 by bolts 24 to improve the stability of the connection between the support 3 and the connecting seat 4, thereby improving the safety of the device. When it is necessary to adjust the relative position between the support 3 and the connecting seat 4, the bolts 24 can be removed and the motor started.

[0028] Horizontally arranged slide rails 25 are fixedly connected to both sides of the top of the support 1 along its length. The outer sides of the slide rails 25 extend to the outside of the support 1. The bottom of the mounting base 2 has a mounting groove adapted to the slide rails 25. The groove 21 of the mounting base 2 is slidably connected to the slide rails 25. Both sides of the mounting base 2 extend to the outside of the support 1, and extensions 26 are fixedly connected to its bottom. One side of the extension 26 is slidably connected to the outer wall of the mounting base 2, and the other side of the extension 26 is slidably connected to the slide rails 25. The slide rails 25 and the mounting grooves facilitate the smoothness and stability of sliding between the support 1 and the mounting base 2. The extensions 26 further improve the stability of the mounting base 2 during the sliding process.

[0029] In another embodiment, two symmetrically arranged buffer components are fixedly connected to the inner sidewall of the stand 3. The two buffer components are respectively located on the stand 3 at both ends of the rack 15. The buffer component located above the rack 15 includes a horizontally arranged connecting plate 27, which is fixedly connected to the stand 3. A horizontally arranged buffer plate 28 is installed below the connecting plate 27. Multiple spaced grooves are opened at the bottom of the connecting plate 27. A vertically arranged sliding column 29 is slidably connected in the groove. The sliding column 29 is fixedly connected to the top of the groove by a compression spring 30. The sliding column 29 extends out of the groove and is fixedly connected to the buffer plate 28. The connecting plate 27 is designed to limit the stroke of the connecting seat 4. However, the connecting seat 4 is prone to touching the connecting plate 27 during lifting, which can affect the lifespan of the connecting plate 27 and the lifting motor 12. By setting a buffer plate 28, after the connecting seat 4 touches the buffer plate 28, the buffer plate 28 moves towards the connecting plate 27 under the contact of the connecting seat 4, so that the compression spring 30 is compressed, thereby reducing the damage to the connecting seat 4 and extending its service life to a certain extent.

[0030] In use, the mold to be flipped is placed on the loading plate 10. The traveling trolley 7 is started, and the traveling trolley 7 moves the mold on the track 9 until it moves between the two supports 1 and stops. The lifting cylinder 20 is started, and the lifting cylinder 20 moves the loading plate 10 upward, so that the hook mold moves towards the adsorption plate 19. When the upper mold touches the adsorption plate 19, the lifting cylinder 20 is closed, and the moving cylinder 11 is started. The moving cylinder 11 moves the two mounting seats 2 closer to each other, and then moves the two clamping plates 6 closer to each other, until the inner sidewalls of the two clamping plates 6 touch the hook mold. The moving cylinder 11 is closed, and the drive motor 16 is started. The output shaft of the drive motor 16 drives the rotating shaft 13 to rotate through the driving gear 17 and the driven gear 18, which in turn drives the clamping plates 6 to rotate, thus realizing the flipping of the hook mold clamped between the two clamping plates 6.
