Description

Technical Field

[0001] The invention relates to the technical field of zinc-based alloy liquid casting equipment, and in particular to automatic zinc-based alloy liquid casting equipment. Background Art

[0002] Zinc-based alloys are alloys formed by adding other elements to zinc as a matrix. In addition to zinc, common added elements include aluminum, copper, magnesium, etc. The addition of these alloying elements can change the properties of zinc so that it can meet different industrial needs. For example, in traditional zinc-aluminum-copper zinc-based alloys, aluminum can improve the casting properties and mechanical properties of the alloy, copper can enhance the strength and hardness of the alloy, and magnesium helps to refine the grains.

[0003] Zinc-based alloys are often made by melting and casting. After melting, the alloy liquid needs to be discharged in time for casting. There are currently two casting methods. One is the direct discharge method, in which the casting liquid is directly discharged into the mold through the liquid guide groove for real-time casting. However, this method requires the amount of casting liquid to match the casting demand, and there is often a mismatch between the casting liquid and the demand; the other is the insulation method, in which the casting liquid is discharged into an insulation furnace for insulation storage, but this method has low casting efficiency and requires material to be taken out and discharged one spoonful at a time.

[0060] Automatic casting equipment includes the following states:

[0061] In the first state, the liquid level of the temporary storage furnace 2 is high, and the main drain tank 3 directly drains the liquid to the drain pipe 322.

[0062] In the second state, the liquid level in the temporary storage furnace 2 is low, and the movable liquid taking assembly 4 is closed to take out the residual liquid in the temporary storage furnace 2 and transfer it to the liquid drain pipe 322;

[0064] In the above scheme:

[0065] 1. The temporary storage furnace can be used to temporarily store the zinc-based alloy liquid smelted in the smelting furnace. The liquid first fills the liquid storage cavity, and then the excess is discharged to the liquid injection component through the main liquid drain tank, the auxiliary liquid drain tank, and the liquid drain pipe, which can meet the full acceptance needs of a single batch of smelting liquid.

[0066] 2. The movable liquid collection component is designed as an openable and closable structure. When it is opened, the movable liquid collection component can be embedded in the main liquid drainage groove. In this way, when the movable liquid collection component moves, it can scrape the waste in the main liquid drainage groove to clean the main liquid drainage groove; when there is no liquid in the upper liquid guide ring and only the bottom of the liquid storage cavity has liquid, it enters the second state. At this time, the movable liquid collection component can be transformed into a closed state, and the liquid in the liquid storage cavity can be obtained to meet the needs of low liquid level loading;

[0067] 3. The liquid injection component can introduce the liquid into the mold body. At the same time, the floating liquid discharge component is designed to realize the gradual discharge from bottom to top. In this way, the alloy liquid flows more smoothly in the mold body with less impact, which can ensure the solidification stability of the alloy liquid and the internal tightness of the alloy liquid is higher;

[0068] 4. The slag scraper assembly can remove the surface of the alloy liquid, that is, remove the oxide scale, and make the surface of the solidified zinc-based alloy block smoother;

[0069] 5. The negative pressure recovery component can extract the waste scraped by the movable liquid extraction component, and can also receive the waste cleaned by the slag shoveling component to realize the recovery of alloy materials.

[0070] In this embodiment, a floating plate 24 that can move up and down is installed on the surface of the inner retaining ring 213. The floating plate 24 is used to push the zinc-based alloy liquid in the liquid storage chamber 212 to float up and down to avoid condensation on the liquid surface; a driving component 25 is installed at the bottom of the floating plate 24, and the driving component 25 includes a movable rod 251, which is symmetrically arranged, and a movable plate 253 is slidably installed on the outside of the movable rod 251. A support column 256 is vertically provided on the surface of the movable plate 253, and the top of the support column 256 is connected to the floating plate 24. A spring 252 is sleeved on the outside of the movable rod 251, and the spring 252 is placed above the movable plate 253. A first motor 254 is provided below the movable plate 253, and a cam 255 is installed at the output end of the first motor 254.

[0071] In the above scheme: the floating plate is designed to push the alloy liquid up and down, so that the liquid can be stirred to prevent the liquid from condensing prematurely and enhance the fluidity of the liquid; the first motor drives the cam to rotate, thereby driving the floating plate to move up and down along the movable rod, and the support column drives the movable plate to move up and down to achieve liquid stirring.

[0072] In this embodiment, the movable liquid extraction component 4 includes an upper guide rail 41, a fixed plate 42, a first gathering cover 45 and a second gathering cover 47.

The connecting block 44 is provided on one side of the top surface of the first gathering cover 45. The other side of the first gathering cover 45 is rotatably connected to the second gathering cover 47 and a second motor 46 is installed at the rotating connection. The first gathering cover 45 and the second gathering cover 47 are both box structures with one end open. The bottom open end of the first gathering cover 45 is provided with a first notch 451, and the bottom open end of the second gathering cover 47 is provided with a second notch 471. The first notch 451 and the second notch 471 are internally installed with blocking components.

[0078] In this embodiment, a receiving groove 48 is opened on the inner side of the first notch 451, and the blocking component includes a blocking plate 481, which is elastically slidably embedded in the receiving groove 48, and the blocking plate 481 extends outward to block the first notch 451 and retracts inward to expose the first notch 451; the inner end of the blocking plate 481 is a cutting edge structure, a first top column 241 is provided in the middle of the top surface of the floating plate 24, and a second top column 321 is provided in the middle of the upper docking hole 323, the top ends of the first top column 241 and the second top column 321 are both hemispherical structures, and the first top column 241 or the second top column 321 are both opened by the upper blocking plate 481.

[0079] In the above scheme: an elastic sealing plate is designed to cooperate with the first top column and the second top column. When the two sets of sealing plates are butt-jointed, the first notch and the second notch can be sealed. When the first top column or the second top column is inserted, the two sets of sealing plates can be separated, and the alloy liquid can be discharged through the area between the sealing plates, making the opening and closing control easier. The hemispherical structure and the blade structure can make the interference between the top column and the sealing plate smoother.

[0080] In this embodiment, the floating drainage component includes an outer constraint tube 77, an inner constraint tube 78, and a side lifting rod 79; the outer constraint tube 77 is vertically fixed to the middle of the top surface of the cover plate 75, the inner constraint tube 78 slides through the middle of the cover plate 75, the inner constraint tube 78 slides and is embedded in the interior of the drainage pipe 322, the outer constraint tube 77 slides on the outer wall of the drainage pipe 322, the bottom end of the inner constraint tube 78 is connected to the side lifting rod 79, the side lifting rod 79 vertically slides through the cover plate 75, and the surface of the cover plate 75 is provided with a third motor 791 for driving the side lifting rod 79 to lift and lower; a drainage valve 781 is installed at the outlet end of the inner constraint tube 78.

[0082] During drainage, the second driving rod drives the cover plate to descend, and the inner and outer constraint tubes follow and descend synchronously. When the cover is in contact and closed with the mold body, the third motor drives the side lifting rod to move downward, and the inner constraint tube extends to the bottom of the mold body. The drain valve opens to drain the liquid. Then the third motor reverses, and the inner constraint tube gradually rises to achieve gradual drainage from the inside to the outside.

[0083] In this embodiment, a cover 76 is provided on the bottom surface of the cover plate 75, and an air supply pipe 751 is connected to the surface of the cover plate 75; the lowering of the cover 76 includes the following steps:
