[0027] like Figure 1-Figure 4 As shown, a moving block 11 is slidably connected inside the cross frame 6, and screw rods are threadedly connected to the inner sides of the four moving blocks 11. The screw rods penetrate the cross frame 6 and are rotatably connected to the cross frame 6. A rotating plate is fixedly provided at one end of the screw rod away from the cross frame 6. Rotating the rotating plate can drive the moving block 11 to slide in the cross frame 6. A pillar 12 is fixedly provided on the bottom surface of the moving block 11, and a bottom plate 13 is fixedly provided on the bottom surface of the pillar 12.

The second spring 17 is fixedly provided on the bottom surface of the bottom plate 13, and the other end of the second spring 17 is fixedly provided with a mounting block 16. The top surface of the mounting block 16 is fixedly provided with a pull rod 15, which penetrates the bottom plate 13 and is slidably connected to the bottom plate 13. The top surface of the pull rod 15 is fixedly provided with a clamping plate 14, and the clamping plate 14 is close to the bottom plate 13 to clamp the mold.

[0028] like Figure 1-Figure 4As shown, a disassembly assembly is arranged inside the lifting bracket 1, and the disassembly assembly consists of a threaded rod 3, a threaded sleeve 4, a first spring 5, a fixed sleeve 7, a steel ball 9 and an insertion rod 10.

A steel ball 9 is rotatably connected to the bottom of the threaded rod 3, and the center of the steel ball 9 is located above the bottom surface of the threaded rod 3. An insertion rod 10 is fixedly arranged at the bottom of the steel ball 9, and a fixed sleeve 7 is slidably connected to the outer side of the insertion rod 10. A bolt 8 is arranged inside the fixed sleeve 7 to penetrate to the outside, and the bolt 8 is threadedly connected to the fixed sleeve 7. The bottom surface of the fixed sleeve 7 is fixedly connected to the top surface of the cross frame 6. Four first springs 5 ​​are fixedly arranged between the outer side of the threaded sleeve 4 and the top surface of the cross frame 6. When the cross frame 6 rotates relative to the lifting bracket 1, the first spring 5 is respectively extended and compressed, and the cross frame 6 can be moved in the process of extension and compression of the first spring 5. The screw threaded sleeve 4 is rotated in the opposite direction, thereby greatly reducing the shaking amplitude of the cross frame 6 when the cross frame 6 moves, improving the stability of the cross frame 6, and preventing the cross frame 6 from hitting other structures. The insertion rod 10 is aligned with the fixed sleeve 7, and the threaded sleeve 4 is rotated to make the threaded sleeve 4 threadedly connected to the threaded rod 3. The rotation of the threaded sleeve 4 drives the threaded sleeve 4 and the disassembly assembly to move upward until the insertion rod 10 is inserted into the fixed sleeve 7 to achieve the installation of the disassembly assembly. The threaded sleeve 4 is rotated in the opposite direction until the threaded sleeve 4 is disengaged from the threaded rod 3, so that the disassembly assembly can be disassembled, thereby facilitating the disassembly and installation of the disassembly assembly. After completing the installation of the disassembly assembly, the cross frame 6 is moved upward to minimize the elongation of the first spring 5. The bolt 8 is rotated so that the bolt 8 presses the insertion rod 10, which can facilitate the insertion rod 10 to replace the first spring 5 to pull the cross frame 6, thereby further improving the stability of the cross frame 6.

[0029] like Figure 1-Figure 4As shown, a lifting assembly is arranged below the cross frame 6, and the lifting assembly consists of a lifting plate 18, an L-shaped plate 19, a through slot 20, a third spring 21, a push plate 22 and a T-shaped slide 23. A lifting plate 18 is arranged below the cross frame 6, and a third spring 21 is fixedly arranged between the top surface of the lifting plate 18 and the bottom surface of the cross frame 6, an L-shaped plate 19 is fixedly arranged on the bottom surface of the lifting plate 18, and the transverse part of the L-shaped plate 19 is symmetrically arranged on the bottom surface of the clamping plate 14, and a T-shaped slide 23 and a through slot 20 penetrating to the top surface are arranged on the bottom surface of the lifting plate 18, and a T-shaped slider adapted to the T-shaped slide 23 is fixedly arranged on the top surface of the L-shaped plate 19, and the T-shaped slider is slidably connected to the lifting plate 18 through the T-shaped slide 23, and the pillar 12 penetrates the lifting plate 18 through the through slot 20, and a symmetrical The push plate 22 can drive the L-shaped plate 19 to move with the movement of the moving block 11 when the moving block 11 is adjusted in position. The side of the L-shaped plate 19 is slidably connected to the push plate 22. Lifting the lifting plate 18 upward can drive the L-shaped plate 19 to move upward at the same time. The third spring 21 is compressed, and the movement of the L-shaped plate 19 drives the clamping plate 14 to move upward at the same time. The second spring 17 is compressed. When the distance between the clamping plate 14 and the bottom plate 13 reaches the maximum, the mold is placed on the top surface of the bottom plate 13, and then the lifting plate 18 is released. The third spring 21 pushes the lifting plate 18 to move downward, and the second spring 17 pushes the mounting block 16 to move downward. The movement of the mounting block 16 drives the clamping plate 14 to move downward, so that the clamping plate 14 cooperates with the bottom plate 13 to clamp and fix the mold on all sides at the same time, thereby improving the efficiency of hoisting the mold.

[0030] Specific working principle:

[0031] When the device is in use, the insertion rod 10 is aligned with the fixed sleeve 7, the threaded sleeve 4 is rotated to make the threaded sleeve 4 and the threaded rod 3 threadedly connected, the rotation of the threaded sleeve 4 drives the threaded sleeve 4 and the disassembly assembly to move upward until the insertion rod 10 is inserted into the fixed sleeve 7, so that the installation of the disassembly assembly is realized, the cross frame 6 is moved upward to minimize the elongation of the first spring 5, and the bolt 8 is rotated so that the bolt 8 presses the insertion rod 10, which can facilitate the insertion rod 10 to replace the first spring 5 to pull the cross frame 6, thereby further improving the stability of the cross frame 6.

[0032] The position of the moving block 11 is adjusted according to the size of the mold. The push plate 22 can drive the L-shaped plate 19 to move with the movement of the moving block 11 when the position of the moving block 11 is adjusted. The lifting plate 18 is lifted upward to drive the L-shaped plate 19 to move upward at the same time. The third spring 21 is compressed, and the movement of the L-shaped plate 19 drives the clamping plate 14 to move upward at the same time. The second spring 17 is compressed. When the distance between the clamping plate 14 and the bottom plate 13 reaches the maximum, the mold is placed on the top surface of the bottom plate 13, and then the lifting plate 18 is released. The third spring 21 pushes the lifting plate 18 to move downward, and the second spring 17 pushes the mounting block 16 to move downward. The movement of the mounting block 16 drives the clamping plate 14 downward The mold can be moved by the clamping plate 14 and the bottom plate 13 at the same time, so that the clamping plate 14 can cooperate with the bottom plate 13 to clamp and fix the four sides of the mold at the same time, thereby improving the efficiency of hoisting the mold. The output end of the hydraulic cylinder 2 is controlled to contract to drive the mold to move upward. The hydraulic cylinder 2 and the slide bar can move left and right along the slide rail to drive the mold to move left and right, so as to realize the hoisting of the mold. When the cross frame 6 rotates relative to the hoisting bracket 1, the first spring 5 is respectively extended and compressed. The cross frame 6 can be rotated in the opposite direction during the extension and compression process of the first spring 5, thereby greatly reducing the shaking amplitude of the cross frame 6 when the cross frame 6 moves, improving the stability of the cross frame 6, and avoiding the cross frame 6 from hitting other structures.

[0033] When the disassembly assembly needs to be disassembled, the bolt 8 is rotated in the reverse direction until the bolt 8 is disengaged from the insertion rod 10, and then the threaded sleeve 4 is rotated in the reverse direction until the threaded sleeve 4 is disengaged from the threaded rod 3, and the disassembly assembly can be disassembled.
