Specific implementation mode

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] Embodiment 1: Please refer to Figures 1-6 , because the length and width of each pair of molds are different, during the placement process, personnel need to adjust the distance between the two supports under the mold for a long time, and each support weighs about 200 KG, and 2 people are required to operate simultaneously to move it, which takes a long time and affects work efficiency. To solve this technical problem, the following technical content is disclosed in this embodiment;

[0037] A mobile support frame for mold maintenance includes two support arms 1. The upper ends of the two support arms 1 are fixedly connected with a lifting plate 2, and the lower ends of the support arms 1 are fixedly connected with a support bottom plate 3. A reinforcement arm 4 is welded between the support arm 1 and the lifting plate 2, and a stiffening rib plate 6 is welded and fixed on the support arm 1; a buffer block 5 is embedded on the lifting plate 2. A limit frame 7 is fixed between the two support arms 1, and a movable frame 8 is arranged below the limit frame 7. Four universal wheels 9 are installed at the bottom of the movable frame 8. A guide rod 10 is fixedly connected to the limit frame 7, and the lower end of the guide rod 10 is inserted into the movable frame 8. A guiding spring 11 is installed between the movable frame 8 and the limit frame 7. The structures of the limit frame 7 and the movable frame 8 are the same, and the limit frame 7 and the movable frame 8 are parallelly distributed, and the movable frame 8 is not connected to the two support arms 1.

[0038] When the mold needs to be supported, the worker can move the entire support frame by pushing the support arm 1, and the four universal wheels 9 at the bottom of the movable frame 8 enable the movement. To make it easier to push the support frame, a foldable handle can be installed on the support arm 1, thus avoiding the need for multiple workers to operate simultaneously. After adjusting the longitudinal distance between the two support frames, use a crane to lift the mold to be repaired onto the lifting plates 2 on the two support arms 1. After the mold is placed on the lifting plates 2, the gravity of the mold is transmitted to the movable frame 8 and the universal wheels 9. At this time, the movable frame 8 moves along the upper part of the guide rod 10, and the elastic deformation of the guiding spring 11 is used for buffering. At this time, the lower surface of the support bottom plate 3 is in full contact with the ground to ensure the stability of the support frame during mold repair.

[0039] Embodiment 2: The technical content disclosed in this embodiment is a further improvement based on the above Embodiment 1. When the mold is placed on the support frame by a crane, however, during the descent of the mold, the bottom of the mold is easily damaged due to the shaking of the mold. To further solve this technical problem, the following technical content is disclosed in this embodiment, as Figures 2-5 shown;

[0040] Pins 12 are inserted into both the movable frame 8 and the limit frame 7. The upper surface of the buffer block 5 is higher than the upper surface of the lifting plate 2, and the buffer block 5 is made of polyurethane material. The limit frame 7 includes a fixed part 701, an adjustment part 702, a clamping post 703, and a through hole 704; the fixed part 701 is fixed on one of the support arms 1, and an adjustment part 702 is provided on the side of the fixed part 701, and the adjustment part 702 is fixed on the other support arm 1. A clamping post 703 is fixedly connected to the adjustment part 702, and the clamping post 703 is inserted into the fixed part 701. Through holes 704 are formed in both the clamping post 703 and the fixed part 701, and a pin 12 is inserted through the through holes 704 in the clamping post 703 and the fixed part 701. The outer wall of the clamping post 703 on the adjustment part 702 fits with the inner wall of the fixed part 701, and multiple through holes 704 are formed in both the clamping post 703 and the fixed part 701. The inner wall of the through hole 704 fits with the outer wall of the pin 12. The movable frame 8 and the guide rod 10 are in sliding connection, and the longitudinal section of the guide rod 10 is set as a "T" - shaped structure.

[0041] Before supporting the mold, pull the support arm 1 on one side. After the support arm 1 moves, it drives the adjustment part 702 to move synchronously. After the adjustment part 702 moves, the clamping column 703 can slide inside the fixing part 701. After the adjustment of the support arm 1 on one side is completed, insert the bolt 12 into the through holes 704 on the fixing part 701 and the clamping column 703 to complete the fixation after the movement adjustment of the two support arms 1. Since the structures of the movable frame 8 and the limit frame 7 are the same, when the limit frame 7 is adjusted horizontally, the movable frame 8 will also perform the same movement adjustment. By adjusting the distance between the two support arms 1, it can adapt to the support of molds with different widths. At the same time, after the mold is lifted and transported to the lifting plate 2, the buffer block 5 made of polyurethane on the lifting plate 2 can protect the mold and prevent wear and scratches on the bottom of the mold.

[0042] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
