Description

Technical Field

[0001] This utility model relates to the field of metal ingot casting, and in particular to a demolding device for nickel-iron ingots. Background Technology

[0002] Nickel-iron alloy is an alloy material mainly composed of nickel and iron. It has good physical and mechanical properties. In the smelting and processing process, it is usually smelted into a molten metal, then poured into an ingot mold, and cooled to form an ingot with a certain shape and size, so as to facilitate subsequent transfer processing.

[0003] In the production process of nickel-iron ingots, several molds are usually fixed on a conveyor belt. The movement of the conveyor belt drives the molds forward. During this process, the smelting equipment pours high-temperature molten metal into the molds by rotating and tilting, thereby achieving continuous and rapid casting operations and significantly improving the efficiency of ingot production. However, in the actual casting process, due to the continuous operation of the conveyor belt, the molten metal is prone to spilling between adjacent molds, causing the cast ingots to have a runny edge. This runny edge not only increases the difficulty of subsequent demolding but may also affect the overall quality of the ingot.

[0004] Meanwhile, during the cooling and forming process, a large number of oxide impurities are generated on the surface of the ingot. Some of these oxide impurities adhere to the surface of the mold, further exacerbating the difficulty of demolding. The presence of these impurities not only affects the appearance quality of the ingot but may also lead to a decline in product performance. Currently, it is difficult to separate oxide impurities when demolding the ingot.

[0005] In summary, this application proposes a nickel-iron ingot demolding device to improve the aforementioned technical problems. Utility Model Content

Beneficial effects

[0013] The moving shovel removes the flow edges from the surface of the casting mold, reducing the difficulty of subsequent demolding. It also moves the movable plate to scrape away the oxide impurities adhering to the casting mold on the surface of the ingot, thus separating the oxide impurities from the casting mold to facilitate subsequent ingot demolding. Furthermore, as the movable plate moves, it also moves the brush to brush away the oxide impurities on the surface of the ingot, preventing the oxide impurities from continuously contacting the ingot and affecting the ingot quality.

[0014] By brushing together the oxide impurities, and with the help of the top plate, the movable side mold is opened, separating the movable side mold from the casting mold and the ingot.

Detailed Implementation

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings. Example

[0018] A nickel-iron ingot demolding device, as described in the following figure Figures 1-5 As shown, it includes a conveyor 1 and a casting mold 2; the conveyor 1 is equipped with several casting molds 2; It also includes a movable shovel plate 3, a movable plate 4, elastic telescopic rods 5, and a demolding unit; each casting mold 2 is slidably connected to a movable shovel plate 3, and the movable shovel plate 3 is in contact with the surface of the casting mold 2; each movable shovel plate 3 is slidably connected to a movable plate 4, and a scraper part 41 is provided on each side of the movable plate 4, which can scrape the inner wall of the casting mold 2 to remove the oxide impurities attached to the surface of the ingot and the inner wall of the casting mold 2; each movable shovel plate 3 is fixedly connected to two elastic telescopic rods 5, and the telescopic part of the elastic telescopic rod 5 is fixedly connected to the movable plate 4; the casting mold 2 is connected to a demolding unit.

[0019] It also includes bristles 6; bristles 6 are provided at the bottom of the movable plate 4.

[0020] The demolding unit includes a movable side mold 7, a sliding rod 8, a spring 9, a push rod 10, and a discharge guide 11; each casting mold 2 is slidably connected to four sliding rods 8; each sliding rod 8 on the same casting mold 2 is fixedly connected to a movable side mold 7; each sliding rod 8 is fixedly connected to a spring 9, and the spring 9 is fixedly connected to the casting mold 2; the casting mold 2 is slidably connected to a push rod 10; the conveyor 1 is fixedly connected to a discharge guide 11.

[0021] The bristles 6 are made of steel wire and can brush off oxide impurities from the surface of the ingot.

[0022] It also includes a top plate 111 and a collection box 112; each movable shovel 3 is fixedly connected to a top plate 111; the discharge guide 11 is bolted to the conveyor 1 and the collection box 112 is connected.

[0023] It also includes a connecting pipe 101; each casting mold 2 is fixedly connected to a connecting pipe 101; the casting mold 2 has a cooling cavity 21, and the cooling cavity 21 is connected to the connecting pipe 101; the movable side mold 7 has a cavity 71; the movable side mold 7 is provided with an insertion interface 72.

[0024] The operation of nickel-iron ingot casting is as follows: The smelting equipment is positioned to the right of conveyor 1. Conveyor 1 is controlled to move the casting mold 2 to the left. When the casting mold 2 is below the smelting equipment, conveyor 1 is stopped. The molten nickel-iron is poured into the casting mold 2 by the rotation of the smelting equipment. After a certain amount of molten metal has been poured into the casting mold 2, conveyor 1 is continued to move the casting mold 2 to the left, moving the next casting mold 2 to the bottom of the smelting equipment. This achieves continuous and rapid casting operations, improving the overall efficiency of ingot casting. As the casting mold 2 continues to convey, when… After cooling and solidification, the movable side mold 7 and sliding rod 8 are moved manually or mechanically to separate the movable side mold 7 from the casting mold 2. Then, the ejector rod 10 is pushed into the casting mold 2 to push out the solidified ingot, allowing it to slide down the discharge guide 11 and be collected, thus completing the ingot production. However, the continuous operation of the conveyor 1 makes it easy for the molten liquid to spill between adjacent casting molds 2 during the pouring process, resulting in runners on the cast ingots. This runner not only increases the difficulty of subsequent demolding but may also affect the overall quality of the ingot. Therefore, when the casting mold 2 is filled with molten liquid... When the ingot cools and solidifies for demolding, the movable shovel 3 is first moved backward along the surface of the casting mold 2 by manual or mechanical means. The moving shovel 3 scrapes off the runner from the surface of the casting mold 2, thus reducing the difficulty of subsequent demolding. Furthermore, during the cooling and forming process, a large amount of oxide impurities are generated on the surface of the ingot. Some of these oxide impurities adhere to the mold surface, further exacerbating the difficulty of demolding. Therefore, during the movement of the movable shovel 3, the movable shovel 3 drives the movable plate 4 to move. When the movable plate 4 detaches from the surface of the casting mold 2, under the action of the elastic telescopic rod 5… The movable plate 4 moves downward, causing the scraper parts 41 on both sides of the movable plate 4 to fit against the inner wall of the casting mold 2. As the movable scraper plate 3 moves, it simultaneously drives the movable plate 4 to move, scraping away the oxide impurities attached to the surface of the ingot and the casting mold 2, thereby separating the oxide impurities from the casting mold 2 to facilitate the subsequent demolding of the ingot. In addition, the movable plate 4 is equipped with steel wire bristles 6. As the movable plate 4 moves, it simultaneously drives the bristles 6 to move, brushing away the oxide impurities on the surface of the ingot, preventing the oxide impurities from continuously contacting the ingot and affecting the quality of the ingot.

[0025] Meanwhile, considering that during ingot demolding, the removed oxide impurities will be collected along with the ingot, and these oxide impurities will reduce the purity of the ingot and affect its quality, therefore, when the flowing edges and oxide impurities on the surface of the ingot are scraped off by the moving shovel plate 3 and the movable plate 4, the brush 6 can brush the oxide impurities scraped off the surface of the ingot, causing them to gather towards the rear of the ingot. As the moving shovel plate 3 continues to move backward, the top plate 111 on the moving shovel plate 3 first contacts the movable side mold 7, and then pushes the movable side mold 7 open through the top plate 111, thus separating the movable side mold 7 from the casting mold 2 and the ingot. Figure 5 As shown, the brush 6 continues to move, brushing off the cleaned oxide impurities, causing them to fall between the movable side mold 7 and the ingot, and be collected in the collection box 112 below. The brush 6 gathers the oxide impurities, and the top plate 111 pushes the movable side mold 7 open, separating the movable side mold 7 from the casting mold 2 and the ingot. The oxide impurities are brushed off and cleaned from between the movable side mold 7 and the ingot, thereby reducing the oxide impurities on the ingot and improving the quality of the ingot. After cleaning the oxide impurities on the surface of the ingot, the movable side mold 7 is pulled open further, and the ingot is pushed out by the push rod 10, allowing it to slide down the discharge guide groove 11.

[0026] Furthermore, considering that existing methods typically involve directly spraying cooling water onto the ingot surface during ingot cooling and shaping, the sprayed cooling water can only contact the upper surface of the ingot, which can easily lead to uneven cooling and thus affect the quality of the ingot; therefore, when cooling the ingot, the external water supply pipe is connected to the connecting pipe 101, and the cooling water is introduced into the cooling chamber 21 through the connecting pipe 101. The cooling water in the cooling chamber 21 is simultaneously introduced into the chamber 71 of the movable side mold 7 through the insertion interface 72, so that the cooling water can cool all surfaces of the ingot and improve the uniformity of ingot cooling.

[0027] In the production process of nickel-iron ingots, several molds are usually fixed on a conveyor belt. The movement of the conveyor belt drives the molds forward. During this process, the smelting equipment pours high-temperature molten metal into the molds by rotating and tilting, thereby achieving continuous and rapid casting operations and significantly improving the efficiency of ingot production. However, in the actual casting process, due to the continuous operation of the conveyor belt, the molten metal is prone to spilling between adjacent molds, causing the cast ingots to have a runny edge. This runny edge not only increases the difficulty of subsequent demolding but may also affect the overall quality of the ingot.

[0028] Meanwhile, during the cooling and forming process, a large number of oxide impurities are generated on the surface of the ingot. Some of these oxide impurities adhere to the surface of the mold, further exacerbating the difficulty of demolding. The presence of these impurities not only affects the appearance quality of the ingot but may also lead to a decline in product performance. Currently, it is difficult to separate oxide impurities when demolding the ingot.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
