[0033] 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.

[0034] Reference Figure 1 , Figure 6 and Figure 7 An embodiment of this utility model is provided: a mold repair flipping device, including a support base 1, a clamping mechanism 2 is provided on the upper side of the support base 1, the clamping mechanism 2 is used to conveniently limit and clamp molds of different sizes, and a rotating mechanism 3 is provided on the top of the support base 1, the rotating mechanism 3 is used to conveniently flip the mold to be processed.

[0035] The clamping mechanism 2 includes a hollow plate 21, which is disposed on the upper side of the support base 1. A rotating rod 22 is rotatably connected to the rear side of the hollow plate 21, and a driven gear 23 is fixedly connected to the outer side of the rotating rod 22. A hollow frame 24 is fixedly connected to the interior of the hollow plate 21. A lead screw 25 is rotatably connected to the left side of the hollow plate 21. The right end of the lead screw 25 passes through the hollow plate 21 and is threadedly connected to a driving rack 26. The driving rack 26 meshes with the driven gear 23. A transmission assembly 27 is disposed on the front side of the hollow plate 21. The transmission assembly 27 includes a top plate 277 and a crank 273. The top plate 277 is fixedly connected to the top of the rotating rod 22, and the rear side of the top plate 277 has four... Each corner is rotatably connected to a second rotating shaft 272. The front side of the hollow plate 21 is provided with multiple limiting grooves 276. The first rotating shaft 271 is slidably connected inside the limiting grooves 276. The multiple first rotating shafts 271 are respectively connected to the corresponding second rotating shafts 272 through the crank rods 273. The front end of the first rotating shaft 271 is provided with an arc-shaped clamping plate 274. A rubber pad 275 is fixedly connected to one side of each of the multiple arc-shaped clamping plates 274. The size of the multiple rubber pads 275 is matched with the size of the corresponding arc-shaped clamping plate 274. The active rack 26 is slidably connected inside the hollow frame 24. The right end of the lead screw 25 is rotatably connected to the inside right side of the hollow plate 21.

[0036] Specifically, the mold is placed at the center of the hollow plate 21, and then the lead screw 25 is rotated. The driving rack 26 on its outer side will move inside the hollow frame 24. At the same time, the driven gear 23 meshing with the driving rack 26 will also rotate, thereby further driving the top plate 277 at the top of the rotating rod 22 to rotate. As the first rotating shaft 271 rotates, the second rotating shaft 272 will also start to rotate through the crank 273. This series of rotational actions will cause the arc-shaped clamping plates 274 around the perimeter to move towards the center, thereby clamping the mold. Therefore, it can accommodate molds of different sizes for clamping. The operation is relatively simple. This design not only improves the maintenance efficiency of the mold, but also better meets the different needs of users.

[0037] Reference Figure 1 , Figure 2 and Figure 5 The rotating mechanism 3 includes a fixed plate 31, which is fixedly connected to the top of the support base 1. An opening groove 32 is provided inside the fixed plate 31. Annular grooves 33 are provided on both the front and rear sides of the opening groove 32. A semi-toothed ring 34 is slidably connected inside the rear annular groove 33. A movable rod 35 is rotatably connected to the rear side of the fixed plate 31. The front end of the movable rod 35 passes through the opening groove 32 and is fixedly connected to a cylindrical gear 36. A connecting rod 37 is fixedly connected to the front side of the semi-toothed ring 34. The front end of the connecting rod 37 passes through the corresponding annular groove 33 and is fixedly connected to an L-shaped plate 38. One side of the L-shaped plate 38 is fixedly connected to the front side of the hollow plate 21. A limit assembly 39 is provided on the rear side of the fixed plate 31.

[0038] Specifically, by rotating the movable rod 35, the cylindrical gear 36 on its outer side will rotate accordingly, and the semi-toothed ring 34 meshing with it will also rotate, thereby driving the connecting rod 37 to move inside the annular groove 33. As the connecting rod 37 moves, the hollow plate 21 will also move accordingly. When the hollow plate 21 moves to the right side position inside the annular groove 33, the clamped mold will also rotate 180 degrees, thus completing the entire flipping action.

[0039] Reference Figure 3 and Figure 4 The limiting component 39 includes a support plate 393, which is fixedly connected to the upper rear side of the fixed plate 31. A T-shaped rod 394 is provided on the top of the support plate 393. A pawl 395 is fixedly connected to the lower middle part of the T-shaped rod 394 through the support plate 393. A spring 391 is provided on the outer side of the T-shaped rod 394. A ratchet 392 is fixedly connected to the rear side of the outer wall of the movable rod 35. The ratchet 392 is engaged with the pawl 395. A crank 4 is fixedly connected to the rear end of the movable rod 35. One end of the spring 391 is fixedly connected to the top of the support plate 393, and the other end of the spring 391 is fixedly connected to the top inner side of the T-shaped rod 394.

[0040] Specifically, the T-bar 394 is moved upwards first. This action will cause the pawl 395 to move upwards as well, thereby releasing the limiting effect on the ratchet 392. In this way, the mold will not easily flip over during maintenance work, thus ensuring the normal progress of maintenance work.

[0041] Reference Figure 2 and Figure 7 Each of the multiple arc-shaped clamping plates 274 has a bolt 5 threadedly connected to its front side, and the rear ends of the multiple bolts 5 pass through the corresponding arc-shaped clamping plate 274 and the first rotating shaft 271 in sequence.

[0042] Specifically, by turning the bolt 5, the limiting fixation of the arc-shaped clamp 274 can be released, and then different clamp shapes can be changed according to the different shapes of the mold.

[0043] Working principle: When using this device, first observe the size of the mold to be repaired, then place it in the center of the hollow plate 21. Then rotate the lead screw 25, and the outer drive rack 26 will move inside the hollow frame 24. The driven gear 23 meshing with it will rotate, thereby driving the top plate 277 at the top of the rotating rod 22 to rotate. The first rotating shaft 271 will rotate accordingly, and the second rotating shaft 272 will also rotate through the crank 273, thereby driving the arc-shaped clamping plates 274 around to move towards the center to clamp the mold. It can limit the clamping of molds of different sizes. The operation is relatively simple. When it is necessary to clamp a square mold, loosen the bolt 5 to release the limiting fixation of the arc-shaped clamping plate 274, and then replace it with a square clamping plate. This can improve the mold repair efficiency and meet the needs of users.

[0044] Furthermore, when comprehensive maintenance of the mold is required, first moving the T-shaped rod 394 upward will cause the pawl 395 to move upward, which can release the limit on the ratchet 392. Then, rotating the movable rod 35 will cause the outer cylindrical gear 36 to rotate, and the half-tooth ring 34 meshing with it will also rotate, thereby driving the connecting rod 37 to move inside the annular groove 33. The hollow plate 21 will also move. When it moves to the right side inside the annular groove 33, the T-shaped rod 394 will be released. At this time, the spring 391 will release its elasticity, causing the pawl 395 to rebound and limit the ratchet 392. At the same time, the clamped mold will rotate 180 degrees. During maintenance work, the mold will not easily rotate, thus ensuring the normal progress of maintenance work.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
