Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy casting technology, and in particular to a discharge block lifting ring and mold. Background Technology

[0002] Aluminum alloys, due to their high strength, low density, and good casting properties, are often used to cast engine parts, impellers, and other components. During casting, molten aluminum alloy is poured from a melting furnace into a casting mold, and the product is obtained after the alloy cools and hardens. After casting, a portion of residual aluminum alloy usually remains in the melting furnace. This residual aluminum alloy needs to be drained into a discharge tank to prevent it from solidifying in the furnace. After the aluminum alloy residue solidifies in the discharge tank, it forms aluminum alloy discharge blocks. These discharge blocks weigh between 100kg and 200kg each. Since there is no connection point, workers need to use tools to knock them out and then transport them away by forklift for reuse. This operation is difficult and prone to safety issues. Therefore, a discharge block lifting ring and a mold for forming the lifting ring are needed. The discharge block lifting ring is made of the same material as the discharge block. The lifting ring can be placed in the discharge tank and solidified together with the aluminum alloy melt, so that the lifting ring can be embedded in the discharge block. This facilitates the connection between the lifting ring and the discharge block for transportation after being connected by a gantry crane. The lifting ring is made by casting mold, and support columns can be formed on the side of the lifting ring to help the lifting ring maintain its angle, so as to facilitate the removal of the discharge block later. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a discharge block lifting ring and a mold. The discharge block lifting ring is made of the same material as the discharge block. The lifting ring can be placed in the discharge trough and solidified together with the molten aluminum alloy, allowing the lifting ring to be embedded in the discharge block. This facilitates transport after connecting the lifting ring to the discharge block using a gantry crane. The lifting ring is made using a casting mold, which can form support columns on the side of the lifting ring to help maintain the angle of the lifting ring, thus facilitating the later lifting of the discharge block.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a discharge block lifting ring, comprising: a lifting ring body, support columns, and protrusions. The lifting ring body is U-shaped or V-shaped. Two support columns are respectively connected to both sides of the open end of the lifting ring body, and the support columns are perpendicular to the side of the lifting ring body. The support columns are used to keep the lifting ring body upright. The protrusions are arranged on both sides of the open end of the lifting ring body, and there are multiple protrusions with a spacing of 3cm to 5cm between them.

[0006] Furthermore, the length of the support column is 15cm to 20cm, the outer diameter of the support column is greater than 30mm, and the side of the support column is provided with a draft angle of 2° to 4°.

[0007] Furthermore, the cross-section of the main body of the lifting ring is trapezoidal, and the long side, short side, and height of the trapezoid are all greater than 30mm.

[0008] Furthermore, the main body of the lifting ring, the support column, and the protrusion are an integral structure, and the main body of the lifting ring, the support column, and the protrusion are all made of aluminum alloy.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Throughout the description, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0021] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0022] like Figures 1 to 2 As shown, one embodiment of this utility model provides a discharge block lifting ring, including: a lifting ring body 1, support columns 2, and protrusions 3. The lifting ring body 1 is U-shaped or V-shaped. Two support columns 2 are respectively connected to the two sides of the open end of the lifting ring body 1, and the support columns 2 are perpendicular to the side of the lifting ring body 1. The support columns 2 are used to keep the lifting ring body 1 upright. The protrusions 3 are arranged on both sides of the open end of the lifting ring body 1, and there are multiple protrusions 3, with a spacing of 3cm to 5cm between the protrusions 3.

[0023] The residual liquid in the smelting furnace is discharged into the flare tank through the flare outlet. A temperature gun is used to observe the solidification of the aluminum alloy in the flare tank. When the edges of the aluminum alloy in the flare tank begin to solidify, the flare block lifting ring is placed into the flare tank using a tool. The lifting ring body 1 is supported by the bottom support column 2, ensuring that the lifting ring body 1 remains upright in the flare tank and preventing the upper part of the lifting ring body 1 from sinking into the molten aluminum alloy. Figure 2As shown, after the aluminum alloy in the discharge trough has completely solidified and cooled, the upper part of the lifting ring body 1 is exposed, providing a position for the gantry crane to lift and transfer it. The discharge can be lifted out of the discharge trough by the gantry crane and the lifting rope, which is convenient for operation and reduces the labor intensity of workers. The material of the discharge block lifting ring is the same as that of the discharge block. When the discharge block is reused later, it is only necessary to put the discharge block into the melting furnace for melting. There is no need to remove the discharge block lifting ring from the discharge block, which is convenient for operation.

[0024] Although the material of the discharge block lifting ring is the same as that of the discharge block, the structure of the lifting ring body 1 and the support column 2 are all made of a size of 30mm or more. The aluminum alloy in the discharge channel solidifies from the edge, indicating that the molten aluminum alloy at that position has dropped to near the melting point. After multiple experiments, when the discharge block lifting ring is placed near the edge where it begins to solidify, the outer surface of the discharge block lifting ring will melt by about 5mm to 10mm. The discharge block lifting ring will not be completely melted by the molten aluminum alloy in the discharge block. Moreover, these melted areas will fuse with the discharge block, improving the connection strength between the discharge block lifting ring and the discharge block.

[0025] When the lifting ring body 1 is embedded inside the discharge block, the support column 2 and the protrusion 3 can increase the connection strength between the lifting ring body 1 and the discharge block, preventing the lifting ring body 1 from being pulled out of the discharge block when it is lifted out, thus improving the connection strength.

[0026] Specifically, the length of the support column 2 is 15cm to 20cm. Since the main body 1 of the lifting ring is flat, it cannot maintain an upright position on its own. Therefore, the support column 2 is set on the side of the main body 1 of the lifting ring. The support column 2 supports the main body 1 of the lifting ring from the side, so that the main body 1 of the lifting ring remains upright in the discharge trough. After the discharge block solidifies, the upper part of the main body 1 of the lifting ring can be exposed, thus forming a ring structure, which is convenient for the gantry crane to lift and transport. The outer diameter of the support column 2 is greater than 30mm, so that the support column 2 has a certain thickness to prevent it from completely melting in the discharge trough. The side of the support column 2 is provided with a demolding slope of 2° to 4° to facilitate demolding when making the discharge block lifting ring.

[0027] Specifically, the cross-section of the lifting ring body 1 is trapezoidal, which gives the side of the lifting ring body 1 a certain demolding angle, making demolding easier. The long side, short side, and height of the trapezoid are all greater than 30mm, giving the lifting ring body 1 a certain thickness to prevent it from being completely melted in the discharge tank. It also ensures that the lifting ring body 1 has a certain structural strength to prevent the lifting ring body 1 from breaking during hoisting and transportation.

[0028] In one specific embodiment, the lifting ring body 1, support column 2, and protrusion 3 are an integral structure. The discharge block lifting ring is a disposable item. The discharge block lifting ring is made by casting to reduce production costs. The lifting ring body 1, support column 2, and protrusion 3 are all made of aluminum alloy. The discharge block lifting ring is made of the same material as the discharge block. When the discharge block is reused later, it is only necessary to put the discharge block into the melting furnace for melting. There is no need to remove the discharge block lifting ring from the discharge block, which is convenient for operation.

[0029] like Figures 3 to 5 As shown, one embodiment of this utility model provides a mold for forming a discharge block lifting ring. The mold includes a forming block 4 and a forming cylinder 5. The forming cylinder 5 is perpendicularly connected to the side of the forming block 4. The forming block 4 is connected to the ground through a support frame. The forming block 4 and the forming cylinder 5 are provided with forming cavities 7 for forming the discharge block lifting ring. The forming cavity 7 on the forming block 4 is used to form the lifting ring body 1 and the protrusion 3. The forming cylinder 5 is used to form the support column 2. When making the discharge block lifting ring, it is only necessary to pour molten aluminum alloy of the same material as the discharge block into the forming cavity 7. After the aluminum alloy has completely cooled, the discharge block lifting ring can be obtained. At the same time, the manufacturing time and material can be written on the discharge block lifting ring with a marker for easy identification during later use.

[0030] In a specific embodiment, such as Figure 4 As shown, the lower part of the molding block 4 and the molding cylinder 5 is provided with an ejector rod 6. One end of the ejector rod 6 passes through the molding block 4 and the molding cylinder 5 and extends into the molding cavity 7. The other end of the ejector rod 6 is provided with a limiting plate 8. The limiting plate 8 is connected to the bottom surface of the molding block 4 and the bottom surface of the molding cylinder 5 by a spring 9. Since the discharge block lifting ring is provided with a long structure such as the support column 2, it is not easy to demold. Therefore, an ejector rod 6 is provided at the lower part of the molding block 4 and the molding cylinder 5. During demolding, the end of the ejector rod 6 can be struck with a hammer. The ejector rod 6 impacts the discharge block lifting ring in the mold, causing the discharge block lifting ring to loosen. After that, the mold is flipped over, and the discharge block lifting ring can be separated from the mold under the action of gravity, thus completing the demolding.

[0031] In a specific embodiment, such as Figure 5 As shown, the insertion end of the ejector rod 6 is tapered. Under the action of the spring 9, the ejector rod 6 tends to move outward. At this time, since the insertion end of the ejector rod 6 is tapered, the tapered insertion end plays a limiting role, preventing the ejector rod 6 from being pulled out. At the same time, the insertion end of the ejector rod 6 is pressed tightly against the through hole, preventing the aluminum alloy melt from leaking out from this position during casting, thus ensuring the normal progress of casting.

[0032] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
