Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy casting technology, specifically to a flow control gate assembly for aluminum alloy casting. Background Technology

[0002] Aluminum alloys are alloys based on aluminum with added amounts of other alloying elements, and are one of the lightest metal materials. Besides possessing the general properties of aluminum, they also exhibit specific alloying characteristics depending on the type and amount of added alloying elements. Aluminum alloys have a low density but high strength, approaching or exceeding that of high-quality steel, and also possess good plasticity, electrical conductivity, thermal conductivity, and corrosion resistance. They are widely used in industry, second only to steel in terms of usage. In the casting of aluminum alloys, flow control gate assemblies are typically used to control the flow of molten aluminum. Flow control gate assemblies are components used in the aluminum alloy casting process to control the flow and pouring of molten metal. Their design and use aim to ensure that molten aluminum alloy enters the mold in a stable and uniform manner, avoiding defects within the casting. The use of flow control gate assemblies helps standardize the casting process, making production more controllable and improving product consistency and stability.

[0003] When using flow control gate components, the molten aluminum may be contaminated by crucible materials, tools, or the operating environment during the melting process, leading to the generation of other metallic or non-metallic impurities. In the existing technology, flow control gate components can usually only control the flow of molten aluminum and cannot effectively filter impurities in the molten aluminum. As a result, impurities are discharged with the molten aluminum and injected into the mold, which affects the effect and quality of aluminum alloy casting. Therefore, in order to solve the above problems, a flow control gate component for aluminum alloy casting is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a flow control gate assembly for aluminum alloy casting, so as to solve the problem mentioned in the background art that the prior art cannot effectively filter impurities in the aluminum liquid, causing impurities to be discharged with the aluminum liquid and injected into the mold, thereby affecting the effect and quality of aluminum alloy casting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flow control gate assembly for aluminum alloy casting, comprising a tank body, the tank body including a flow channel, a drain port being provided on the inner side of the flow channel, a fixing block being fixedly connected to the upper surface of the flow channel, a screw being movably connected to the inner side of the fixing block, a moving rod being threadedly connected to the surface of the screw, a flow control plug being fixedly connected to the bottom end of the moving rod, a limit rod being fixedly connected to the inner surface of the fixing block, the moving rod and the limit rod being movably connected, and a drain pipe being fixedly connected to the surface of the flow channel;

[0006] A filtration mechanism is provided on the inner side of the flow channel. The filtration mechanism includes a limiting plate, which is fixedly connected to the inner wall of the flow channel. A first baffle is provided on the inner side of the limiting plate, and a mesh is provided on the inner side of the first baffle. A movable rod is movably connected to the inner side of the flow channel, and a pull block is fixedly connected to the surface of the movable rod. A slot is opened on the surface of the first baffle, and a first spring is fixedly connected to the surface of the pull block.

[0007] Preferably, the limiting plates are fixedly connected to the inner wall of the flow channel in two sets, the movable rods are movable in two sets on the inner side of the flow channel, and the pull blocks are connected to the movable rods in two sets.

[0008] Preferably, the slots are formed in two sets on the surface of the first baffle, one end of the first spring is fixedly connected to the flow channel, and the other end of the first spring is fixedly connected to the pull block.

[0009] Preferably, a flow-slowing mechanism is provided on the inner side of the drain pipe. The flow-slowing mechanism includes a connecting block, which is fixedly connected to the inner wall of the drain pipe. A second baffle is movably connected to the surface of the connecting block, and a second spring is fixedly connected to the surface of the second baffle.

[0010] Preferably, the second baffle is movably connected by a rotating shaft and a connecting block, and the second baffle is staggered on the inner side of the drain pipe.

[0011] Preferably, one end of the second spring is fixedly connected to the drain pipe, and the other end of the second spring is fixedly connected to the second baffle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The first baffle filters the molten aluminum entering the flow channel, intercepting impurities and ensuring the quality of the molten aluminum. Simultaneously, as the molten aluminum passes through the first baffle, air bubbles are eliminated, reducing defects in aluminum alloy casting and improving casting quality. The movable rod allows for insertion and separation from the slot, facilitating the fixing and removal of the first baffle for easy cleaning or replacement, thus ensuring its effective filtration.

[0014] By setting up a second baffle and working in conjunction with the second spring, the second baffle moves when impacted by the molten aluminum during discharge. The molten aluminum encounters resistance as it passes through the second baffle, which reduces its flow rate and slows down the flow. This facilitates the slow and even discharge of the molten aluminum, thereby reducing splashing during injection and making casting safer. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 One embodiment provided by this utility model:

[0022] A flow control gate assembly for aluminum alloy casting includes a tank body, which includes a flow channel 1. A drain port 11 is provided on the inner side of the flow channel 1. A fixing block 12 is fixedly connected to the upper surface of the flow channel 1. A screw 13 is movably connected to the inner side of the fixing block 12. A moving rod 14 is threadedly connected to the surface of the screw 13. A flow control plug 15 is fixedly connected to the bottom end of the moving rod 14. A limiting rod 16 is fixedly connected to the inner surface of the fixing block 12. The moving rod 14 and the limiting rod 16 are movably connected. A drain pipe 17 is fixedly connected to the surface of the flow channel 1. By rotating the screw 13 and cooperating with the action of the limiting rod 16, the moving rod 14 can move horizontally under the action of the screw 13. As a result, the flow control plug 15 moves accordingly, and can move into or out of the inner side of the drain port 11. This can achieve the purpose of blocking the drain port 11 and controlling the flow of aluminum liquid.

[0023] A filtration mechanism is provided on the inner side of the flow channel 1. The filtration mechanism includes a limiting plate 2, which is fixedly connected to the inner wall of the flow channel 1. A first baffle 21 is provided on the inner side of the limiting plate 2, and a mesh is provided on the inner side of the first baffle 21. A movable rod 22 is movably connected to the inner side of the flow channel 1, and a pull block 23 is fixedly connected to the surface of the movable rod 22. A slot 24 is opened on the surface of the first baffle 21, and a first spring 25 is fixedly connected to the surface of the pull block 23. By setting the first baffle 21, impurities in the aluminum liquid can be filtered, and bubbles can be eliminated when the aluminum liquid passes through the first baffle 21, which helps to ensure the quality of aluminum alloy casting.

[0024] Furthermore, the limiting plates 2 are fixedly connected to the inner wall of the flow channel 1 in two sets, the movable rods 22 are movable in two sets on the inner side of the flow channel 1, and the pull blocks 23 are connected to the movable rods 22 in two sets. Through the movement of the movable rods 22, they can be inserted into and separated from the slots 24, thereby realizing the limiting and unlimiting of the first baffle 21, which makes it easy to remove the first baffle 21 for cleaning or replacement, and can ensure the filtering effect of the first baffle 21 on the aluminum liquid.

[0025] Furthermore, the slots 24 are arranged in two sets on the surface of the first baffle 21. One end of the first spring 25 is fixedly connected to the flow channel 1, and the other end of the first spring 25 is fixedly connected to the pull block 23. By setting the first spring 25, the pull block 23 can be reset, and then the movable rod 22 is reset under the action of the pull block 23, and can be inserted into the slot 24, thereby fixing the first baffle 21 and making the first baffle 21 more stable inside the flow channel 1.

[0026] Furthermore, a flow-slowing mechanism is provided on the inner side of the drain pipe 17. The flow-slowing mechanism includes a connecting block 3, which is fixedly connected to the inner wall of the drain pipe 17. A second baffle 31 is movably connected to the surface of the connecting block 3, and a second spring 32 is fixedly connected to the surface of the second baffle 31. Through the setting of the second baffle 31 and the action of the second spring 32, when the aluminum liquid is discharged from the drain port 11 and enters the drain pipe 17, the second baffle 31 can slow down the flow of the aluminum liquid, so that the flow rate of the aluminum liquid decreases, making it easier for the aluminum liquid to be discharged slowly and evenly, thereby reducing splashing when injected into the mold.

[0027] Furthermore, the second baffle 31 is movably connected to the connecting block 3 via a rotating shaft. The second baffle 31 is staggered inside the drain pipe 17. By setting the second baffle 31, the discharged aluminum liquid can be blocked, so that the flow rate of the aluminum liquid will slow down when it passes through the second baffle 31.

[0028] Furthermore, one end of the second spring 32 is fixedly connected to the drain pipe 17, and the other end of the second spring 32 is fixedly connected to the second baffle 31. The second baffle 31 can be reset by the setting of the second spring 32.

[0029] Working principle: During use, the limiting plate 2 positions the first baffle 21. The first baffle 21 intercepts and filters impurities in the molten aluminum, ensuring the quality of the molten aluminum and eliminating air bubbles, thus improving the quality of aluminum alloy casting. By pulling the pull block 23, the movable rod 22 can be moved, separating the movable rod 22 from the slot 24. At this time, the first spring 25 is stretched, allowing the first baffle 21 to be removed from the limiting plate 2 for cleaning or replacement. When the first baffle 21 needs to be installed, it is inserted into the inside of the limiting plate 2, and the pull block 23 is released. The pull block 23 will return to its original position under the rebound of the first spring 25, and the movable rod 22 will also return to its original position and engage with the slot 24, thus fixing the first baffle 21.

[0030] When the molten aluminum flows out through the drain port 11, the second baffle 31 is impacted by the molten aluminum and moves through the rotating shaft. At this time, the second spring 32 deforms and applies a certain force to the second baffle 31, so that the second baffle 31 can block the molten aluminum. Under the action of the second baffle 31, the flow rate of the molten aluminum decreases, and it can flow out and be injected into the mold evenly and slowly.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
