Description

Technical Field

[0001] The utility model relates to the technical field of metal ingot casting, in particular to a non-ferrous metal oxygen-free ingot casting machine. Background Art

[0002] In the process of non-ferrous metal smelting, disc ingot casting machines or linear ingot casting machines are mostly used. During the pouring process, the high-temperature molten metal will form an oxide film due to contact with the air. In order to ensure the appearance quality of the metal ingot, the surface oxide layer needs to be removed before the molten metal crystallizes after pouring. Manual slag removal is completed under high temperature and high labor intensity, which poses a safety hazard of high-temperature molten metal splashing and scalding workers. At the same time, the slag removal process entrains the metal raw liquid, reducing the direct metal recovery rate of the ingot casting process, especially for more expensive metals, which directly causes greater economic losses.

[0003] CN204817956U discloses a device for non-ferrous metal oxygen-free ingot casting, which uses vacuum or inert gas protection in the ingot casting process to prevent the generation of oxide film during the metal ingot casting process, in order to solve the problem that the metal cadmium ingot is oxidized and difficult to demold during the ingot casting process. However, in the production process, it is found that the problem of demolding difficulty is not caused by the oxide film. Even a smooth ingot mold will adhere to the refined cadmium ingot after repeated use, making it difficult to demold the cadmium ingot. Therefore, a casting machine that is convenient for demolding is needed. Utility Model Content

DETAILED DESCRIPTION

[0040] The present invention is further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0041] Example 1

[0042] like Figure 1-2 As shown, this embodiment provides a non-ferrous metal oxygen-free ingot casting machine, including: a closed shell 1, an ingot mold 4, a demoulding component, a cleaning component and an ingot scooping mechanism, wherein the closed shell 1 is a semi-closed structure as a whole, and a sealing cover 11 is provided on the top, and the sealing cover 11 is combined with the closed shell 1 using a sealing ring, and the interior is divided into an ingot casting area, a conveying area and an ingot tapping area connected in sequence, and the heights of the ingot casting area, the conveying area and the ingot tapping area decrease step by step, and the conveying area and the ingot tapping area are both inclined downward to facilitate the subsequent scooping of the metal ingot. A sealing partition 7 is provided between the conveying area and the ingot tapping area, and below the sealing partition 7 is a channel for the metal ingot to pass through, and a displacement pipe is provided on the sealing partition 7, and the displacement pipe connects the ingot casting area and the conveying area, and is used to use the atmosphere gas to displace the oxygen in the ingot casting area and the conveying area. The upper part of the ingot discharge area is an open structure, and the interior is sealed with a sealing liquid (pure water in this embodiment). The sealing liquid submerges the bottom of the sealing partition 7, and the ingot casting area and the conveying area are isolated from the atmosphere by the liquid sealing principle of water. The oxygen inside the ingot casting area and the conveying area is replaced by atmospheric gas to form an oxygen-free area.

[0043] A feed pipe 2 is provided on the left side of the closed shell 1, and a pneumatic discharge valve 21 is provided on the feed pipe 2 for quantitative discharge. A discharge pipe 22 is provided at the end of the feed pipe 2, and a probe 3 is installed at the outlet end of the discharge pipe 22 for detecting the level of the molten metal in the ingot mold 4. The discharge pipe 22 is installed on a bracket 23, and the outlet section of the feed pipe 2 extends into the inlet section of the discharge pipe 22 to achieve docking of the two, while not affecting the rotation and lifting of the discharge pipe 22.

[0044] like Figure 3-4 As shown, the bracket 23 is installed at the output end of the rotary pressing cylinder 24, and the rotary pressing cylinder 24 can drive the bracket 23 and the discharge pipe 22 to move up and down and swing. When discharging, the rotary pressing cylinder 24 drives the discharge pipe 22 to rotate and press down, so that it is in a low position and extends into the ingot mold 4 for discharging. After the discharge is completed, the rotary pressing cylinder 24 drives the rotation to rise to make way for the rotation position of the ingot mold 4, so as to ensure the smooth subsequent demoulding and flipping of the ingot mold 4.

[0045] The ingot mold 4 is located on the right side of the discharge pipe 22 and is turned over by a turning motor. A water jacket is provided on the ingot mold 4 to quickly cool the metal liquid in the ingot mold 4 .

[0046] The demoulding assembly includes: a demoulding push rod 41 and a demoulding cylinder 42. The demoulding push rod 41 penetrates into the ingot mold 4 from the bottom of the ingot mold 4, and the bottom is located just above the output end of the demoulding cylinder 42. The demoulding push rod 41 can be pushed up by the demoulding cylinder 42 to push out the metal ingot in the ingot mold 4, thereby realizing the separation of the metal ingot and the ingot mold 4.

When the ingot mold 4 needs to be cleaned, the ingot mold 4 rotates 90° clockwise so that the notch of the ingot mold 4 faces the cleaning roller brush 52. At the same time, the cleaning roller brush swing arm 51 is swung to swing the rotating cleaning roller brush 52 into the ingot mold 4, and the cleaning roller brush 42 is used to clean and polish the inside of the ingot mold 4. After the polishing is completed, it is reset and the ingot casting is continued.

[0048] Furthermore, a downwardly inclined chute 6 is provided in the conveying area. After the metal ingot is lifted up and demolded by the demolding ejector 41, the ingot mold 4 flips toward the conveying area, and the metal ingot therein falls into the chute 6 and enters the ingot discharge area along the chute 6, finally falls into the sealing liquid, and finally falls onto the ingot catching mechanism and is scooped out by the ingot catching mechanism.

[0049] Specifically, the ingot catching mechanism includes an ingot catching arm 8, which is L-shaped as a whole and driven by a swing motor to swing up and down to achieve the function of catching the ingot and the falling of the ingot catching arm 8.

[0050] The ingot scooping arm 8 extends into the sealing liquid. After the metal ingot falls onto the ingot scooping arm 8 along the inclined surface of the ingot discharging area, the ingot scooping arm 8 is driven to rotate upward, thereby scooping out the metal ingot and realizing automatic ingot discharging.
