[0004] Existing metal mold repair equipment typically lacks lifting capabilities, requiring repair personnel to frequently adjust their own position or the mold's placement, which is extremely inconvenient and significantly impacts repair efficiency. Furthermore, its mold fixing and angle adjustment functions are inadequate, with a limited clamping method, and it is difficult to conveniently adjust the mold angle when not clamped, failing to meet the needs of diverse repair scenarios.

[0005] Therefore, a lifting platform that facilitates the maintenance of metal molds is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a lifting platform that facilitates the maintenance of metal molds. It has the advantages of eliminating the need for maintenance personnel to frequently bend over or elevate the equipment, effectively improving the convenience and efficiency of maintenance operations, and allowing for convenient inspection and maintenance of the mold from different angles, thus providing greater flexibility for maintenance work.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lifting platform for easy metal mold repair, comprising a base plate, a lifting mechanism fixedly connected to the top of the base plate, the lifting mechanism comprising four fixed frames, all four fixed frames being fixedly connected to the base plate, two corresponding fixed frames being rotatably connected to a connecting plate, the inner surfaces of the four fixed frames being rotatably connected to a rotating shaft, two connecting plates being fixedly sleeved to the rotating shaft, one end of one fixed frame being fixedly connected to a lifting motor, the output end of the lifting motor being fixedly connected to the rotating shaft, one corresponding end of each of the two connecting plates being rotatably connected to a connecting rod, one opposite end of each of the two connecting rods being rotatably connected to a support plate, the top of the two support plates being fixedly connected to a worktable, and a clamping mechanism being installed at the top of the worktable.

[0010] Preferably, a support plate is rotatably connected to the top center of the workbench via a bearing, and the top of the support plate is engraved with anti-slip texture.

[0011] Preferably, four support rods are fixedly connected to the bottom end of the bearing plate, and an annular groove is provided at the top end of the workbench, with the four support rods slidably connected to the annular groove.

[0012] Preferably, the clamping mechanism includes a clamping motor, one end of which is fixedly connected to the worktable.

[0026] 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.

[0027] like Figures 1 to 4As shown, this utility model provides a lifting platform for easy maintenance of metal molds, including a base plate 1, and a lifting mechanism 3 is fixedly connected to the top of the base plate 1;

[0028] The lifting mechanism 3 includes four fixed frames 31, which are all fixedly connected to the base plate 1. Two corresponding fixed frames 31 are rotatably connected to a connecting plate 36. The inner surfaces of the four fixed frames 31 are rotatably connected to a rotating shaft 35. Two connecting plates 36 are fixedly sleeved with the rotating shaft 35. One end of one fixed frame 31 is fixedly connected to a lifting motor 34. The output end of the lifting motor 34 is fixedly connected to the rotating shaft 35. One corresponding end of each of the two connecting plates 36 is rotatably connected to a connecting rod 37. One opposite end of each of the two connecting rods 37 is rotatably connected to a support plate 38. The top of the two support plates 38 is fixedly connected to a worktable 4. The lifting motor 34 drives the rotating shaft 35 to rotate, which in turn moves the connecting plate 36, connecting rod 37, and support plate 38, thereby raising and lowering the worktable 4. This allows maintenance personnel to adjust the mold maintenance height according to their needs, improving maintenance convenience. A clamping mechanism 5 is installed at the top of the worktable 4.

[0029] Specifically, the bottom of the base plate 1 is fixedly connected to four brake wheels 2 arranged in a rectangular array. The brake wheels 2 on the base plate 1 allow the lifting platform to be easily moved to the required position. After reaching the position, the platform is locked by braking, which facilitates flexible adjustment of the lifting platform position to adapt to different maintenance scenarios.

[0030] like Figures 1 to 4 As shown, four outer rods 32 arranged in a rectangular array are fixedly connected to the top of the base plate 1. Inner rods 33 are slidably connected to the inner surfaces of the four outer rods 32. The four inner rods 33 are fixedly connected to the worktable 4. The cooperation between the outer rods 32 and the inner rods 33 provides guidance for the lifting and lowering of the worktable 4, ensuring that the worktable 4 remains stable during the lifting and lowering process, avoiding shaking, and improving the accuracy of lifting and lowering.

[0031] Furthermore, a bearing plate 41 is rotatably connected to the top center of the worktable 4 via a bearing. The top of the bearing plate 41 is engraved with anti-slip texture. The bearing plate 41 can rotate around the bearing, which makes it convenient for maintenance personnel to flexibly adjust the mold angle. At the same time, the anti-slip texture can prevent the mold from sliding on the bearing plate 41, improving operational safety.

[0032] like Figures 1 to 4 As shown, four support rods 412 are fixedly connected to the bottom end of the bearing plate 41, and an annular groove 411 is provided at the top of the worktable 4. The four support rods 412 are slidably connected to the annular groove 411. The sliding cooperation between the support rods 412 and the annular groove 411 provides stable support for the rotation of the bearing plate 41, ensuring that the rotation of the bearing plate 41 is smooth and stable, and helping maintenance personnel to adjust the mold angle more easily.

[0033] It is worth noting that the clamping mechanism 5 includes a clamping motor 51. One end of the clamping motor 51 is fixedly connected to the worktable 4. Two long slots 54 are opened at the top of the worktable 4. The inner surfaces of the two long slots 54 are rotatably connected to a bidirectional lead screw 55. The output end of the clamping motor 51 passes through the worktable 4 and is fixedly connected to the bidirectional lead screw 55. Moving blocks 57 are threadedly sleeved at the points where the bidirectional lead screw 55 has threads in different directions. The top of each of the two moving blocks 57 is fixedly connected to a clamping plate 52. The corresponding ends of the two clamping plates 52 are fixedly connected to a clamping block 53. The clamping motor 51 drives the bidirectional lead screw 55 to rotate, which drives the moving blocks 57, clamping plates 52 and clamping blocks 53 to move, so as to realize the rapid and firm clamping of molds of different sizes and improve the efficiency of maintenance work.

[0034] like Figures 1 to 4 As shown, each of the two clamping blocks 53 has a soft pad 56 fixedly connected to one end. Both soft pads 56 are made of rubber. The rubber soft pads 56 on the clamping blocks 53 can increase the friction with the mold, prevent damage to the mold surface during clamping, and enhance the stability and reliability of clamping.

[0035] It is worth emphasizing that the height of the two clamping blocks 53 is higher than the height of the support plate 41. The height of the clamping blocks 53 is higher than that of the support plate 41, which can prevent the clamping blocks 53 from contacting the support plate 41 when clamping the mold, and effectively prevent the support plate 41 from being damaged by the force applied by the clamping blocks 53.

[0036] The clamping motor 51 and the lifting motor 34 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switches, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0037] Working principle and process: In use, firstly, the lifting platform is moved to the required maintenance work area by using the brake wheel 2. After the position is determined, the brake wheel 2 is locked by the braking device to make the lifting platform stop stably. Then, the lifting motor 34 is started. The output end of the lifting motor 34 drives the rotating shaft 35 to rotate. The rotation of the rotating shaft 35 will drive the connecting plate 36 to rotate around the fixed frame 31. The connecting plate 36 will drive the connecting rod 37 to move accordingly. The connecting rod 37 will then drive the support plate 38 to move. Under the push of the connecting rod 37, the worktable 4 will be raised or lowered. During this process, the outer rod 32 and inner rod 33 fixedly connected to the top of the base plate 1 play a guiding role. The inner rod 33, in sliding cooperation with the outer rod 32, ensures that the worktable 4 rises and falls smoothly in the vertical direction until the worktable 4 is adjusted to a suitable height for maintenance operation.

[0038] The metal mold is placed on the support plate 41 at the top center of the workbench 4. The anti-slip texture on the top of the support plate 41 can initially prevent the mold from sliding. Then, the clamping motor 51 is started. The output end of the clamping motor 51 passes through the workbench 4 and drives the bidirectional lead screw 55 in the long slot 54 to rotate. The bidirectional lead screw 55 will drive the two moving blocks 57 to move in opposite directions. The clamping plate 52 and clamping block 53 fixedly connected to the top of the moving block 57 also move accordingly until the two clamping blocks 53 firmly clamp the mold. The rubber pad 56 on the clamping block 53 not only ensures the stability of the clamping, but also prevents the mold surface from being damaged by the clamping.

[0039] During maintenance, if it is necessary to adjust the mold angle, turn on the clamping motor 51 in the reverse direction to release the mold. Since the bearing plate 41 is rotatably connected to the worktable 4 through the bearing, after releasing the mold, the maintenance personnel can directly rotate the bearing plate 41 manually to rotate the mold to the appropriate angle, and then perform clamping maintenance. In addition, the design of the clamping block 53 being higher than the bearing plate 41 can prevent the clamping block 53 from contacting the bearing plate 41 when clamping the mold, effectively preventing the bearing plate 41 from being damaged by the force applied by the clamping block 53.
