[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0028] like Figure 1 - Figure 4 As shown, the device for lifting and flipping a long strip mold of this embodiment comprises a mold carrier 1 for carrying a mold 4, and end support structures 2 for supporting the mold carrier 1 are installed at both ends of the mold carrier 1. The mold carrier 1 is rotatably connected with the end support structures 2, and a driving structure 3 for driving the mold carrier 1 to flip is installed on the end support structure 2 on one side. When working, the mold 4 is first placed on the mold carrier 1, and the mold 4 and the mold carrier 1 are connected by screws. The mold carrier 1 is used as a carrier during the flipping process of the mold 4, and is used to fix and drive the mold 4 to flip. Then, the mold carrier 1 and the mold 4 are hoisted as a whole to the end support structure 2. The two end support structures 2 serve as support members for the mold carrier 1 and the mold 4. The driving structure 3 is used to provide power for the flipping of the mold carrier 1 and the mold 4 to realize the flipping of the mold 4. The driving structure 3 can be an electric structure or a manual structure.
[0029] In this embodiment, a middle support structure 5 is installed between the two end support structures 2 to assist in lifting the mold carrier 1 and the mold 4. The middle support structure 5 is used to assist in supporting the middle position between the mold carrier 1 and the mold 4, ensuring that the mold 4 has good stability while flipping, and can ensure that the mold 4 does not produce deformation that affects the accuracy.
[0030] In this embodiment, the mold carrier 1 includes a supporting frame 11 , both ends of the supporting frame 11 are fixedly connected with a rotating shaft 12 , the rotating shaft 12 is rotatably connected to the end support structure 2 , and the mold 4 is connected to the supporting frame 11 by bolts.
[0031] In this embodiment, the end support structure 2 includes an end frame platform 21, and a roller seat 22 is fixedly installed on the upper surface of the end frame platform 21. The roller seat 22 is provided with a groove 221 for placing the rotating shaft 12. A clamp 222 is hinged on the groove 221, and the rotating shaft 12 is rotatably connected to the roller seat 22. The roller seat 22 is used to support the rotating shaft 12 and is a bearing platform for the rotating shaft 12. When working, the clamp 222 is closed to ensure the stability of the rotating shaft 12 when rotating.
[0032] In this embodiment, the driving structure 3 includes a handwheel 31 and a worm gear reducer 32. The handwheel 31 is connected to the input end of the worm gear reducer 32, and the output end of the worm gear reducer 32 is connected to the rotating shaft 12. The rotating handwheel 31 drives the rotating shaft 12 to rotate, thereby realizing the flipping of the mold 4. The worm gear reducer 32 reduces the rotation speed of the handwheel 31 and increases the torque of the handwheel 31, so that the mold 4 can be flipped with a smaller force, which greatly saves manpower.
[0033] In this embodiment, the middle support structure 5 includes a middle frame platform 51, an arc-shaped movable swing arm 52 is installed on the upper surface of the middle frame platform 51, and rollers 53 are movably connected at both ends of the movable swing arm 52. Fork arms 54 are symmetrically installed on both sides of the movable swing arm 52 along the length direction. One end of the fork arm 54 is hinged to the upper surface of the middle frame platform 51, and the other end of the fork arm 54 is fixedly connected to a locking member 55. A circular support ring 56 is connected to the locking member 55. The mold 4 and the mold carrier 1 are covered in the support ring 56. The mold carrier 1 is bolted to the support ring 56, and the support ring 56 is rollingly connected to the roller 53. The movable swing arm 52 is used to hold up the mold 4 in the support ring 56. The movable swing arm 52 can swing left and right, so that it can be automatically adjusted according to the actual placement position of the middle support structure 5. The movable swing arm 52 contacts the support ring 56 through the roller 53, which greatly reduces the friction when the support ring 56 flips.
[0034] In this embodiment, the locking member 55 includes a U-shaped block 551 for auxiliary support of the support ring 56. A latch 552 is installed at the opening of the U-shaped block 551. The U-shaped block 551 is fixedly connected to the fork arm member 54. The U-shaped block 551 is sleeved on the outside of the support ring 56. One end of the latch 552 passes through the support ring 56 and the U-shaped block 551. When the mold 4 and the mold carrier 1 are lifted, the latch 552 is inserted into the U-shaped block 551 and the support ring 56 for fixing. When the mold 4 and the mold carrier 1 are turned over, the latch 552 is pulled out, and the support ring 56 rotates in the U-shaped block 551.
[0035] In this embodiment, the support ring 56 includes a support portion 561 and a closing portion 562. One end of the support portion 561 and the closing portion 562 are hinged, and the other end of the support portion 561 and the closing portion 562 are connected by bolts. After the closing portion 562 and the support portion 561 are opened and the mold 4 and the mold carrier 1 are placed, the closing portion 562 and the support portion 561 are closed and locked by bolts. The support ring 56 rotates and rotates with the mold 4 and the mold carrier 1.
[0036] In this embodiment, a first leg 211 for adjusting the horizontal position of the end frame platform 21 is installed at the bottom of the end frame platform 21. The first leg 211 is used to stabilize the end frame platform 21 on the uneven ground, thereby increasing the stability of the device.
[0037] In this embodiment, a second leg 511 for adjusting the horizontal position of the middle frame platform 51 is installed at the bottom end of the middle frame platform 51. The second leg 511 is used to stabilize the middle frame platform 51.
[0038] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and changes obtained without departing from the technical concept of the present invention should also be regarded as the protection scope of the present invention.
