[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In the process of using this utility model, since the lower ends of a pair of hydraulic cylinders are mounted on a pair of first rotating fixed hinge seats and the upper ends of a pair of hydraulic cylinders are movably mounted on a pair of second rotating fixed hinge seats, the existing equipment uses hydraulic cylinders to push the molten iron ladle. The molten iron ladle has a high temperature, which causes great damage to the rubber seals inside the hydraulic cylinder. After long-term use, it is easy to age and cause oil leakage inside the hydraulic cylinder. Therefore, it is necessary to improve the molding equipment for steel structure casting to solve the above problems. Utility Model Content

[0006] In order to overcome the problem that existing equipment uses hydraulic cylinders to push molten iron ladles, the molten iron ladles have a high temperature, which causes great damage to the rubber seals inside the hydraulic cylinders, and long-term use can easily lead to aging and oil leakage inside the hydraulic cylinders.

[0007] The technical solution of this utility model is as follows: a molding device for steel structure casting includes a conveying unit, the top of which can drive the casting box to move.

A spring can pass through the guide rod and be positioned between the semi-circular head and the vertical plate. The semi-circular head can fit into the metal solution tank.

[0009] Preferably, a flat plate is welded to the left side wall of the metal solution tank, and the spherical surface of the semi-circular head is tangent to the flat plate.

[0010] Preferably, there are two guide holes, which are arranged in the front-to-back direction. Guide rods are inserted into the two guide holes, and the semi-circular heads on the right side of the two guide rods can fit against the flat plate.

[0011] Preferably, the bottom of the molten metal container is welded with a hook hole that can be coupled to a chain. Pulling the chain to the left will cause the bottom of the molten metal container to deflect to the left.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5This utility model provides an embodiment: a molding device for shaping steel structure castings, including a conveying unit 4, the top of which can drive a casting box 41 to move. The casting box 41 has a receiving hole 411 on its top. It also includes a base plate 11, a placement platform 12 on the top of the base plate 11, a vertical plate 13 on the left side of the top of the placement platform 12, a horizontal plate 14 on the top of the vertical plate 13, and a flipping part on the top of the horizontal plate 14. Two support plates 6 are also provided on the top of the placement platform 12, and a metal solution tank 2 is rotatably connected between the two support plates 6. A pouring port 21 is provided on the right side of the metal solution tank 2. With the axis pointing to the upper right, a spring-loaded part is provided on the left side of the molten metal tank 2. Rotating shafts are provided on the front and rear sides of the molten metal tank 2, and the spring-loaded part is located below the rotating shafts. The spring-loaded part can push the bottom of the molten metal tank 2 to the left. The spring-loaded part includes a spring 52, and the flipping part includes a receiving roller 33. An iron chain is wound on the receiving roller 33. Through the cooperation of the flipping part and the spring-loaded part, the molten metal tank 2 is rotated, so that the molten metal tank 2 can pour out molten steel, reducing the impact of the heat of the molten steel on the oil and rubber parts in the hydraulic cylinder. The spring 52 of the spring-loaded part can resist the molten metal tank 2 to prevent the molten metal tank 2 from being over-poured and causing production accidents.

[0023] Please see Figure 1 - Figure 4 In this embodiment, the flipping part also includes a guide hole 131 penetrating the vertical plate 13. A guide rod 53 is inserted into the guide hole 131. A semi-circular head 51 is provided on the right side of the guide rod 53. A spring 52 can pass through the guide rod 53 and is positioned between the semi-circular head 51 and the vertical plate 13. The semi-circular head 51 can fit against the metal solution tank 2. The guide hole 131 limits the guide rod 53, so that the guide rod 53 can only move along the axis of the guide rod 53, increasing stability. The guide rod 53 can fit against the metal solution tank 2. The spring 52 can squeeze the semi-circular head 51, causing the semi-circular head 51 to push to the left. A flat plate 23 is welded to the left side wall of the metal solution tank 2. The spherical surface of the metal solution tank 2 is tangent to the plate 23. The semi-circular head 51 is tangent to the plate 23. When the metal solution tank 2 rotates, the semi-circular head 51 is always tangent to the plate 23, making the rotation of the metal solution tank 2 more stable. There are two guide holes 131, which are arranged in the front-back direction. Guide rods 53 are inserted into the two guide holes 131 respectively. The semi-circular head 51 on the right side of the two guide rods 53 can fit against the plate 23. The two guide holes 131 increase the thrust on the metal solution tank 2. At the same time, the two guide rods 53, together with the spring 52, can prevent the metal solution tank 2 from tipping over when a single guide rod 53 and spring 52 are damaged, thus increasing safety.

[0024] Please see Figure 2 - Figure 5In this embodiment, a hook hole 22 is welded to the bottom of the molten metal tank 2. The hook hole 22 can be coupled to an iron chain. Pulling the iron chain to the left can cause the bottom of the molten metal tank 2 to deflect to the left. The hook hole 22 facilitates the iron chain to pull the molten metal tank 2 to rotate, so that the molten metal tank 2 can inject molten steel into the casting box 41. A rotating first steering roller 31 is provided on the right side of the vertical plate 13. The iron chain can fit against the left side of the first steering roller 31. A second steering roller 32 is provided on the right side of the vertical plate 13 above the first steering roller 31. The iron chain can fit against the right side of the second steering roller 32. L-shaped mounting brackets 331 are provided on the top of the horizontal plate 14 on both sides of the receiving roller 33. A motor 33 is installed on the side of one of the L-shaped mounting brackets 331 away from the receiving roller 33. 2. The output shaft of motor 332 is connected to the storage roller 33. By rotating the first steering roller 31 and the second steering roller 32, the storage roller 33 can store or release the chain without interference. Baffles are provided on both sides of the axis of the first steering roller 31, the second steering roller 32 and the storage roller 33, and the chain can pass through the gap between the two springs 52. Second fixing plates 321 are provided on both sides of the axis of the second steering roller 32, and the second steering roller 32 is rotatably connected to the second fixing plate 321. First fixing plates 311 are provided on both sides of the axis of the first steering roller 31, and the first steering roller 31 is rotatably connected to the first fixing plate 311. The baffles can prevent the chain from slipping out from the first steering roller 31, the second steering roller 32 and the storage roller 33, causing the chain to derail.

[0025] During operation, the conveying unit 4 first moves the casting box 41 to a suitable position via the alignment device. The conveying unit 4 and alignment device have the same structure as those in the comparative document, and their working principle will not be repeated here. Then, the motor 332 drives the receiving roller 33 to rotate, and the receiving roller 33 receives the iron chain. At this time, the iron chain, through the rotation of the first steering roller 31 and the second steering roller 32, pulls the hook hole 22 to the left, causing the top of the molten metal tank 2 to rotate to the right. The spring 52 contracts, squeezing the semi-circular head 51 to the right to prevent the molten metal tank 2 from deflecting excessively. The tilted molten metal tank 2 allows the molten steel inside to flow out from the pouring port 21, and then falls into the casting box 41 through the receiving hole 411. Subsequently, the receiving roller 33 is driven by the motor 332 to release the iron chain, the spring 52 relaxes, and the molten metal tank 2 returns to its initial state. Molten steel can no longer flow out of the molten metal tank 2.

[0026] Through the above steps, the metal molten steel tank 2 is rotated by the cooperation of the flipping part and the spring part, so that the metal molten steel tank 2 can be poured out, reducing the impact of the heat of the molten steel on the oil and rubber parts in the hydraulic cylinder. The spring 52 of the spring part can resist the metal molten steel tank 2 to prevent the metal molten steel tank 2 from being over-poured and causing production accidents. This solves the problem in the existing technology where the equipment uses a hydraulic cylinder to push the molten iron tank, the molten iron tank has a high temperature, which causes great damage to the rubber seals in the hydraulic cylinder, and long-term use is prone to aging and oil leakage in the hydraulic cylinder.
