[0026] Embodiment 1 Please refer to Figures 1-6 , the present utility model provides a technical solution: a casting mold for a plate-spliced H-shaped steel for an assembled steel structure building, comprising: a lower mold body 1 and an upper mold body 2, the upper mold body 2 is disposed on the upper surface of the lower mold body 1, and the upper mold body 2 is used to cover the lower mold body 1, so the lower mold body 1 is set to be larger. A symmetric pouring groove 4 is formed at the top of the upper mold body 2, and the pouring groove 4 is used for pouring therein. A push-pull plate is disposed in the pouring groove 4, and the push-pull plate is used to cover the pouring groove 4 to prevent impurities or dust from falling into the mold after placement, and at the same time, it is also for better sealing after casting. Protrusion blocks 6 are fixedly installed inside both the upper mold body 2 and the lower mold body 1. Cavities are provided on both sides of the protrusion block 6 in the upper mold body 2, and the cavity part is an H-shaped part that needs to be filled. The cavity is communicated with the pouring groove 4. After the upper mold body 2 is covered, pouring needs to be carried out from the pouring groove 4. A first addition plate 7 is installed on the protrusion block 6, and the first addition plate 7 is used to raise the protrusion block 6, so that the distance between the two protrusion blocks 6 becomes shorter. The distance between the two protrusion blocks 6 is approximately the thickness in the middle of the H-shaped plate. An upper movable plate 12 is provided on the inner wall of the upper mold body 2, and a lower movable plate 9 is provided on the inner wall of the lower mold body. The upper movable plate 12 and the lower movable plate 9 are used to clamp the second addition plate 10 to be added, so that the second addition plate 10 can tightly fit against the side walls of the upper mold body 2 or the lower mold body 1.

[0027] The first addition plate 7 can be not installed or multiple can be installed. The number of installed plates needs to be determined according to the needs of engineers. When installation is required, it can be tightened with screws. The first addition plate 7 includes a main board 22 and a convex plate 23. The convex plate 23 is provided to facilitate the installation of the next first addition plate 7. When installing the next first addition plate 7, the screws on the previous first installation plate need to be removed, and then the screws are added to the new first installation plate. The screws can tightly install all the first installation plates on the raised block 6. A groove 21 is formed on the main board 22, and the groove 21 is also for facilitating installation. The groove 21 just snaps into the convex plate 23. The main board 22 of the first first addition plate 7 is arranged on the raised block 6, and subsequent addition plates only need to be added on the previous addition plate. The raised block 6 extends into the groove 21 and is slidably connected thereto. A convex plate 23 is fixedly installed on one side of the main board 22, and the convex plate 23 is provided for the convenience of installing the next first addition plate 7.

[0028] When in actual use, to ensure the symmetry of the H-shaped steel plate, when adding a first addition plate 7 on the raised block 6 of the upper die body 2, a first addition plate 7 also needs to be added on the raised block 6 of the lower die body 1. When adding the second first addition plate 7, the groove 21 of the second first addition plate 7 will snap into the convex plate 23 of the first first addition plate 7. Therefore, the groove 21 of each first addition plate 7 is provided for stable connection with the previous raised block 6 or the first addition plate 7, and the convex plate 23 of each first addition plate 7 is provided for the convenience of installing the next first addition plate 7. In the gap after such setting and pressing, molten metal will not easily enter during pouring. During pouring, first pour the lower die body 1. After the lower die body 1 is filled, it needs to be vibrated, and a stirring rod is used to stir inside to make there be no bubbles inside. Then cover the upper die body 2 and stir from the pouring groove 4. During this process, the upper and lower die bodies 1 need to be tightly pressed together by a machine.

[0029] Embodiment 2 Please refer to Figures 4-6, on the basis of the first embodiment, a lower concave block 13 is fixedly connected to the bottom of the upper movable plate 12. The thickness of the lower convex block is only half of that of the upper movable plate 12, and one surface of the lower convex block is exactly on the same plane as the upper movable plate 12. A nut groove 14 is formed on the side surface of the upper movable plate 12. The nut groove 14 is provided to ensure that the nut will be completely clamped into the nut groove 14 after use, making it look like a complete plane. In this way, when pouring again, not too many marks will be left on the H-shaped steel plate, and only slight polishing is needed. An upper convex block 15 is fixedly connected to the top of the lower movable plate 9. The thickness of the upper convex block 15 is half of that of the lower movable plate 9. The length, width, and thickness of the upper movable plate 12 and the lower movable plate 9 are the same. A plurality of strip-shaped blocks 11 are installed on one side of the lower movable plate 9. Two thin steel wires 16 are fixedly connected to each strip-shaped block 11. The thin steel wires 16 are convenient for bundling and connecting. One end of the steel wire is connected to the fixing component 5. The fixing component 5 is used to connect the thin steel wires 16 and tighten and fix them. A plurality of strip-shaped blocks 11 are installed on one side of the lower movable plate 9. The strip-shaped blocks 11 will tightly adhere to the inside of the lower movable plate 9 under the tension of the thin steel wires 16. The strip-shaped blocks 11 are half of the lower movable plate 9. When the strip-shaped blocks 11 are embedded in the lower movable plate 9, the plane of the lower movable plate 9 will merge with the plane of the strip-shaped blocks 11. Two thin steel wires 16 are fixedly connected to each strip-shaped block 11. The thin steel wires 16 are used to pull the strip-shaped blocks 11 so that they are completely embedded in the lower movable plate 9. One end of the steel wire is connected to the fixing component 5. After installation, the thin steel wires 16 can be tightened through the fixing component 5.

[0030] During actual use, if the second adding plate 10 needs to be added, the thin steel wire 16 needs to be detached from the fixing component 5, and then the lower movable plate 9 is removed, together with the strip-shaped blocks 11. Then, after installing the second adding plate 10, the thin steel wire 16 is passed through the through hole on the second adding plate 10. After passing through, the thin steel wire 16 is connected to the fixing component 5, and after connection, it can be tightened through the fixing component 5. When an adding plate needs to be added between the upper movable plate 12 and the upper die body 2, the screw needs to be removed first, and then the second adding plate 10 is installed. After installation, the movable plate is installed, and finally it is fixed with screws.

[0031] Embodiment Three Please refer to Figures 6-7, on the basis of the second embodiment, the fixing component 5 includes a fixing cylinder 17, a locking column 18 and a fixing handle 19. One end of the fixing cylinder 17 is fixedly connected to the outer side wall of the lower die body 1. The inner wall of the fixing cylinder 17 is provided with threads. The locking column 18 extends into the fixing cylinder 17 and is threadedly connected thereto. In this way, the locking column 18 can be moved outwards by rotation. The fixing handle 19 is fixedly connected to one end of the locking column 18. The thin steel wire 16 passes through the fixing cylinder 17 and the locking column 18 and is fixedly connected to the fixing handle 19. Therefore, when the locking column 18 moves towards the outside of the fixing cylinder 17, the fixing handle 19 will drive the thin steel wire 16 away from the fixing cylinder 17, so that it can be tightened. The steel wire is tied to the fixing handle 19. The farther the fixing handle 19 is from the fixing cylinder 17, the greater the tension of the thin steel wire 16, but it is necessary to ensure that the locking column 18 does not leave the fixing cylinder 17.

[0032] A second adding plate 10 can be provided between the lower movable plate 9 and the inner wall of the lower cover plate and between the upper movable plate 12 and the upper die body 2. The setting of the second adding plate 10 needs to be determined according to specific circumstances. If thicker side plates of the H shape are required, the second adding plate 10 does not need to be added. When not added, the H-shaped steel plate injection molded is the thickest steel plate that this mold can inject.

[0033] During actual use, when adding a first adding plate 7, a first adding plate 7 also needs to be added to the raised block 6 of the lower die body 1. When adding the second first adding plate 7, the groove 21 of the second first adding plate 7 will be stuck on the convex plate 23 of the first first adding plate 7. Therefore, the groove 21 of each first adding plate 7 is provided for stable connection with the previous raised block 6 or the first adding plate 7, and the convex plate 23 of each first adding plate 7 is provided for the convenient installation of the next first adding plate 7. In the gap after such setting and pressing, metal liquid will not easily enter during pouring. During pouring, first pour the lower die body 1. After the lower die body 1 is filled, it needs to be vibrated, and a stirring rod is used to stir inside to make there be no bubbles inside. Then cover the upper die body 2 and stir it from the pouring groove 4. During this process, the upper and lower die bodies 1 need to be tightly pressed together by a machine. If the second adding plate 10 needs to be added, the thin steel wire 16 needs to be separated from the fixing component 5, then the lower movable plate 9 is removed, and the strip-shaped block 11 is removed together. Then, after installing the second adding plate 10, the thin steel wire 16 is passed through the through hole on the second adding plate 10. After passing through, the thin steel wire 16 is connected to the fixing component 5, and after connection, it can be tightened by the fixing component 5. When an adding plate needs to be added between the upper movable plate 12 and the upper die body 2, the screws need to be removed first, then the second adding plate 10 is installed. After installation, the movable plate is installed, and finally it is fixed by screws. When not added, the H-shaped steel plate injection molded is the thickest steel plate that this mold can inject.

[0034] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
