Description

Technical Field

[0001] The utility model relates to the technical field of distribution bags, in particular to a distribution bag suitable for casting large-size 8-series high-iron aluminum alloy flat ingots. Background Art

[0002] 8 series aluminum alloy has excellent mechanical processing properties. The aluminum foil blanks processed by it are widely used in deep-drawing packaging products and high-performance electronic products. However, compared with other alloys, 8 series alloy has a higher iron content, the melt has better fluidity, and the liquid-solid coexistence zone is narrow. During the casting process (especially the filling stage), aluminum leakage is very likely to occur, resulting in defective ingots or even casting failure. After the aluminum liquid comes out from the outlet on the side of the distribution bag, it flows directly to the small surface of the ingot (such as Figure 4 As shown in the figure, it is very easy to leak aluminum from small faces and corners at the beginning of casting, which leads to defective ingots or even casting failure. Therefore, it is necessary to modify the existing tooling to make it more suitable for the production of high-iron aluminum alloy flat ingots. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1:

[0018] See also Figure 1 and Figure 3The utility model provides a technical solution: a distribution bag suitable for casting large-size 8-series high-iron aluminum alloy flat ingots, comprising a glass fiber mesh 1 with an opening on the top and arranged in a rectangular box shape, the outer side of the glass fiber mesh 1 is wrapped and covered with a glass fiber cloth 2, and corresponding side flow holes 3 are opened on both sides of the glass fiber cloth 2, and a chute connected to the side flow hole 3 is provided on the top of the glass fiber cloth 2, and an adjustment plate is slidably arranged inside the chute, and two bottom flow holes 4 with symmetrical arrangements and adjustable effective sizes are provided at the bottom of the glass fiber cloth 2. The aluminum liquid flows out from the side flow holes 3 and the bottom flow holes 4 through the distribution bag, thereby playing a diversion role on the melt and distributing the metal flow to various positions of the ingot starter.

[0019] Furthermore, the adjustment plate includes an adjustment plug plate 6 slidably arranged inside the slide groove, and an adjustment hole 61 is opened at the lower end of the side of the adjustment plug plate 6 corresponding to the side flow hole 3, and the height of the adjustment hole 61 is smaller than the height of the side flow hole 3; when it is necessary to adjust the size of the side flow hole 3 to adjust the diversion effect, the adjustment plug plate 6 with the adjustment hole 61 of the appropriate size is selected, and the adjustment plug plate 6 is inserted into the slide groove. At this time, the bottom of the adjustment hole 61 is flush with the bottom of the side flow hole 3, and the adjustment plug plate 6 blocks a part of the upper side of the side flow hole 3, so that the part of the side flow hole 3 that can pass the aluminum liquid becomes smaller, thereby adjusting the diversion effect.

[0020] Furthermore, an insertion hole 21 is provided at the upper end of the outer side of the glass fiber cloth 2 to facilitate fixing of the distribution bag.

[0021] Furthermore, a horizontal slide groove connected to the bottom flow hole 4 is provided in the bottom inner cavity of the glass fiber cloth 2, and a bottom plate 5 for adjusting the bottom flow hole 4 is slidably provided inside the horizontal slide groove, and a rectangular hole 51 corresponding to the bottom flow hole 4 is provided on the bottom plate 5; when it is necessary to adjust the size of the bottom flow hole 4 to adjust the diversion effect, the bottom plate 5 is moved horizontally, and the bottom plate 5 moves in the horizontal slide groove, so that a part of the rectangular hole 51 enters the glass fiber cloth 2. At this time, the overlapping part of the rectangular hole 51 and the bottom flow hole 4 is reduced, thereby adjusting the diversion effect.

[0022] The distribution bag provided in this embodiment can adjust the diversion effect according to the ingot casting process and is suitable for the casting of various ingots. Embodiment 2:

[0023] See also Figure 2 , which is different from the first embodiment in that: the adjustment plate includes a sealing plate 62 slidably arranged inside the chute. When casting 8 series aluminum alloy ingots, in order to reduce the speed of aluminum liquid flowing to the small surface and alleviate the problem of excessive flow rate of the 8 series alloy melt, the sealing plate 62 is inserted into the chute to block the side flow hole 3. At this time, the aluminum liquid no longer flows out through the side flow hole 3, thereby reducing the possibility of aluminum leakage from the small surface and corners, which is more suitable for the production of high-iron aluminum alloy flat ingots.

[0024] The utility model can adjust the effective size of the side flow hole 3 and the bottom flow hole 4 or block them, which can effectively reduce the speed of aluminum liquid flowing to the small surface, alleviate the problem of excessively fast melt flow rate of 8 series alloy, thereby reducing the possibility of aluminum leakage from the small surface and corners, facilitating the casting of ingots, and making it more suitable for the production of high-iron aluminum alloy flat ingots.

[0025] The undisclosed parts in the present utility model are all prior art, and their specific structures, materials and working principles are not described in detail. Although the embodiments of the present utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model, and the scope of the present utility model is defined by the attached claims and their equivalents.
