Description

Technical Field

[0001] The invention relates to the field of inclined casting devices, in particular to a leak-proof inclined casting device. Background Art

[0002] During the casting process, since the casting pot cannot completely pour the molten liquid into the mold, the molten liquid remaining in the bottom of the casting pot will gradually cool and condense into continuous flaky residues, and as the number of castings of the casting pot increases, the flaky residues on the bottom of the casting pot will gradually condense and thicken to form a residue layer with a relatively high thickness. Therefore, after casting, it is very important to clean the bottom of the casting pot regularly. The staff needs to clean the condensed residues on the bottom of the pot to prevent the condensed residues on the bottom of the pot from being injected into the mold in the form of a small amount of solid debris during the subsequent casting process to ensure the smooth progress of the subsequent casting process. The staff generally uses a cleaning brush to clean the condensed residues on the bottom of the pot. This cleaning method has a poor cleaning effect on the residues and it is difficult to completely clean the condensed residues on the bottom of the pot. In addition, during this process, the cleaning brush reciprocates to clean the bottom of the casting pot, which is likely to cause irreparable scratches on the bottom of the casting pot. These scratches will further cause the accumulation of residues, increasing the overall difficulty of cleaning the casting pot in the later stage. Summary of the invention

[0026] A leakproof tilting casting device, such as Figure 1-Figure 7As shown, the invention comprises a tilting machine 1, a tilting frame 11, an upper opening and closing mold set 12, a lower opening and closing mold set 13, a casting pot 2, an air flow splitter 3, an air inlet nozzle 31, an air jet column 32, an arc-shaped push block 33, a pull block 34, and an electric push rod 4; the upper opening and closing mold set 12 and the lower opening and closing mold set 13 are sequentially installed on the tilting frame 11 of the tilting machine 1, and both the upper opening and closing mold set 12 and the lower opening and closing mold set 13 have lifting cylinders and corresponding The upper and lower half-molds are composed of corresponding half-molds, and the half-molds on the upper and lower sides are synchronously controlled by two lifting cylinders to close and open; a casting pot 2 is fixedly connected to the turning frame 11; a casting liquid flow channel 201 is opened on the rear side of the casting pot 2; a casting liquid inlet 202 structure connected to the upper opening and closing mold group 12 and the lower opening and closing mold group 13 is opened on the casting liquid flow channel 201 of the casting pot 2; a plurality of plug holes 203 structures are opened at the bottom of the casting pot 2, and the plug holes 203 are composed of a lower cylindrical structure and an upper inverted cone structure; an air flow diverter plate 3 is slidably connected to the lower side of the casting pot 2; an air inlet nozzle 31 is connected to the air flow diverter plate 3; an air jet column 32 structure corresponding to the number of plug holes 203 is connected to the air flow diverter plate 3, and the air jet column 32 is adapted to the corresponding plug hole 203 structure, that is, the air jet column 32 is also composed of a lower cylindrical structure and an upper inverted cone structure; the upper inverted cone structure of each air jet column 32 is provided with a plurality of upper spray holes 3201 structures with the outlet end facing downward; a long strip plug groove 204 structure is provided in the casting liquid flow channel 201 of the casting pot 2; an arc-shaped push block 33 is inserted in the plug groove 204; the arc-shaped push block 33 is fixedly connected to the adjacent air jet column 32; a pull block 34 structure is provided on the air flow diverter plate 3; a high-temperature resistant electric push rod 4 is installed on the casting pot 2; the telescopic end of the electric push rod 4 is fixedly connected to the pull block 34.

[0027] like Figure 7 As shown, each jet column 32 is provided with a plurality of lower jet holes 3202 , which are located below the upper jet hole 3201 of the same jet column 32 , and are configured as strip-shaped slit structures elongated in the vertical direction; and each jet column 32 is fixedly provided with an intercepting cone 321 .

[0028] The casting working steps of a leak-proof inclined casting device of the present invention are as follows.

[0029] First, the upper and lower half molds are closed synchronously by two lifting cylinders. At this time, the casting port 202 of the casting pot 2 is connected to the liquid inlet channel formed by the closing of the half molds on both sides. The staff then pours the molten liquid into the casting pot 2. At this time, the jet column 32 is tightly plugged in the plug hole 203 of the casting pot 2, and the upper inverted cone structure of the jet column 32 and the upper inverted cone structure of the plug hole 203 form a leakage-proof sealing structure, so that the molten liquid in the casting pot 2 will not leak out through the plug hole 203, and then the flip-type tilting machine 1 controls the flip frame 11 to synchronously drive the upper opening and closing mold group 12, the lower opening and closing mold group 13 and the casting pot 2 to tilt and flip backward, so that the molten liquid in the casting pot 2 flows through the casting liquid flow channel 201 and the casting port 202 in turn and is poured into between the upper opening and closing mold group 12 and the lower opening and closing mold group 13 to complete the casting work.

[0030] The steps for regular cleaning of a leak-proof inclined casting device of the present invention are as follows.

[0031] As the casting pot 2 completes the pouring and casting of the molten liquid many times, a layer of residue will gradually condense on the bottom of the casting pot 2 during the cooling waiting period after each casting work, and the residue will gradually thicken as the number of casting works increases. During the regular cleaning of the bottom of the casting pot 2, the bottom of the casting pot 2 is first cooled statically to allow the residue on the bottom of the casting pot 2 to gradually cool and shrink into a large-area continuous sheet-like thin layer solid shape. At the same time, the air inlet nozzle 31 of the air flow diverter plate 3 is externally connected to a low-temperature insulating gas conveying device, and then the low-temperature insulating gas conveying device conveys low-temperature insulating gas to each jet column 32 of the air flow diverter plate 3 through the air inlet nozzle 31. At the same time, the telescopic end of the electric push rod 4 pulls the pull block 34 to drive the air flow diverter plate 3 to move upward, and the air flow diverter plate 3 drives the jet column 32 to rise slightly upward, so that the upper part of the jet column 32 is inverted cone shaped structure is separated from the upper inverted cone structure of the plug hole 203. At this time, an annular micro-gap structure is formed between the upper inverted cone structure of the jet column 32 and the upper inverted cone structure of the plug hole 203, while the lower nozzle 3202 of the jet column 32 is still in the plug hole 203, so that the low-temperature insulating gas flowing through the jet column 32 can only flow out through the upper nozzle 3201, and the outflowing low-temperature insulating gas passes through the annular micro-gap structure on the plug hole 203 and diffuses from the center to the surroundings into the contact surface between the residue and the bottom of the casting pot 2. At the same time, the low-temperature insulating gas can further cool the residue and condense it into a continuous thin layer of solid residue. In the process of diffusion of the insulating gas between the thin layer of solid residue and the contact surface of the bottom of the casting pot 2, the thin layer of solid residue is forcibly peeled off from the bottom of the casting pot 2, thereby improving the cleaning effect of the residue.

[0032] During this period, the jet column 32 will also drive the arc-shaped push block 33 to move upward away from the plug groove 204 of the casting pot 2, and the low-temperature insulating gas flowing out from the upper spray hole 3201 of the jet column 32 adjacent to the arc-shaped push block 33 will quickly diffuse to both sides from the gap between the arc-shaped push block 33 and the plug groove 204, thereby realizing the synchronous peeling off of the condensed residues on the casting liquid flow channel 201 in the casting pot 2 in the above-mentioned treatment method.

[0033] After the thin layer of solid residue is completely peeled off from the bottom of the casting pot 2, the telescopic end of the electric push rod 4 further pulls the pull block 34 to drive the air flow diverter plate 3 to move upward, and the air flow diverter plate 3 drives the jet column 32 to lift the peeled thin layer of solid residue upward. When the lower spray hole 3202 on the jet column 32 moves upward away from the plug hole 203, the low-temperature insulating gas flowing through the jet column 32 will preferentially be ejected upward from the lower spray hole 3202. At the same time, the low-temperature insulating gas conveying equipment increases the conveying flow rate of the low-temperature insulating gas, so that the upward-flowing low-temperature insulating gas blows the peeled thin layer of solid residue upward into a suspended state, which is convenient for the staff to pick up the peeled thin layer of solid residue from the casting pot 2 and end the regular cleaning work.

[0034] In addition, since the lower spray hole 3202 is configured as a strip seam structure elongated in the vertical direction, when the jet column 32 is propped up, even if there is a small amount of uncondensed high-temperature molten liquid in the casting pot 2, it is difficult for the high-temperature molten liquid to pass through the lower spray hole 3202 of the strip seam structure and enter the intercepting cone 321. In addition, the jet column 32 also has an intercepting cone 321 for intercepting the high-temperature molten liquid passing through the lower spray hole 3202, thereby ensuring that the high-temperature molten liquid does not flow into the airflow diverter plate 3 along the jet column 32.

[0035] Example 2

[0036] On the basis of Example 1, Figure 1-Figure 7 As shown, a large-area sunken groove 301 structure is provided on the top of the air flow diverter plate 3; a sealing column 322 structure is provided on each jet column 32; a slot 205 structure corresponding to the corresponding sealing column 322 is provided at the bottom of each plug hole 203 of the casting pot 2; a discharge groove 3401 structure connected to the groove 301 is provided on the pull block 34; an accumulation groove 3402 structure connected to the discharge groove 3401 is provided at the lower end of the pull block 34; the entire surface of the pull block 34 is sprayed with a bright paint different from the color of the molten liquid, such as yellow paint or red paint, so that the paint color on the surface of the pull block 34 is clearly distinguished from the color of the molten liquid. When the molten liquid leaked from the casting pot 2 flows through the discharge groove 3401, the staff can clearly see the molten liquid flowing on the discharge groove 3401, even if the staff finds that the casting pot 2 is leaking.

[0037] In this embodiment, as the casting pot 2 is used for many years, the jet column 32 slides up and down in the plug hole 203 of the casting pot 2 for a long time. There is a small probability that the plug hole 203 will leak molten liquid due to excessive wear. The molten liquid leaking downward from the wear area of ​​the plug hole 203 of the casting pot 2 will flow downward into the groove 301 of the air flow splitter 3, and the leaked molten liquid will be intercepted and collected by the groove 301 of the air flow splitter 3. As more and more molten liquid is collected in the groove 301, the molten liquid will pass through the drain groove 301. 401 flows and accumulates in the accumulation groove 3402. When the staff observes the presence of molten liquid in the discharge groove 3401 and the accumulation groove 3402, it will be noticed that the casting pot 2 is leaking. At this time, the staff promptly controls the electric push rod 4 to control the electric push rod 4 to pull the pull block 34 to drive the air flow diverter plate 3 and the jet column 32 connected thereto to move upward, so that the sealing column 322 on the jet column 32 is promptly inserted into the corresponding slot 205 of the casting pot 2, thereby realizing emergency leakage prevention treatment of the casting pot 2.

[0038] Example 3

[0039] On the basis of Example 2, Figure 1-Figure 7 As shown, a thermal switch 35 is installed at the bottom of the pull block 34 , and the thermal switch 35 is electrically connected to the electric push rod 4 through a circuit system; a fuse 351 of the thermal switch 35 runs through the accumulation groove 3402 of the pull block 34 .

[0040] In this embodiment, when the plug hole 203 of the casting pot 2 leaks, the molten liquid leaked into the top groove 301 of the airflow diverter plate 3 accumulates in the accumulation groove 3402 along the discharge groove 3401 of the pull block 34. At this time, the molten liquid instantly burns out the fuse 351 of the thermal switch 35, so that the thermal switch 35 is triggered and sends an emergency avoidance signal to the electric push rod 4 through the circuit system. The electric push rod 4 actively pulls the pull block 34 to drive the airflow diverter plate 3 and the jet column 32 connected to it to move upward, so that the sealing column 322 on the jet column 32 is promptly inserted into the corresponding slot 205 of the casting pot 2, thereby realizing active emergency leakage prevention treatment of the casting pot 2.

[0041] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
