Description

Technical Field

[0001] The present invention relates to the technical field of casting shunting, and particularly to an auxiliary device for the production of high-performance tool die steel. Background Art

[0002] The casting shunting device for the production of high-performance tool die steel is a device that realizes the shunting and balanced flow of molten metal during the casting process, and is used to ensure the quality and surface finish of the casting. The main purpose of the casting shunting device is to ensure that the molten metal flows evenly and smoothly into the mold cavity during pouring, avoiding defects such as turbulence, gas entrainment, and slag inclusion, thereby improving the quality of the casting. Its main structure includes a shunt pipe and a gate. The specific working process is as follows: install the shunting device at the casting furnace mouth, open the casting furnace, load the high-temperature die steel into the furnace and heat it into molten metal, slowly inject the molten metal into the mold through the shunt pipe, ensure that the molten metal flows evenly and is shunted to each part, after pouring, let the metal in the mold cool and solidify, take out the finished product after it has completely cooled, check the quality and surface finish of the finished product, and perform subsequent processing and machining as required.

[0003] For the existing auxiliary device for the production of high-performance tool die steel, after use, the molten metal remaining at the bottom end of the outer wall of the shunt pipe will condense into blocks, which will seriously block the shunt pipe when severe. And there will be molten metal remaining in the inner wall of the shunt pipe, which will adhere to the inner wall of the shunt pipe after cooling. After long-term use, the inner wall of the shunt pipe will thicken, thus affecting the shunting efficiency. The existing device only simply cleans the outer wall or the inner wall of the shunt pipe, rather than cleaning the inner and outer walls of the shunt pipe in combination, so the cleaning effect on the shunt pipe is not ideal, and thus the shunting efficiency of the shunt pipe is not high. And there are still fine debris and residual dust adsorbed on the inner wall of the shunt pipe after cleaning, so the cleaning effect is not good. Summary of the Invention

[0004] (I) Technical Problems to be Solved Aiming at the deficiencies of the existing technology, the present invention provides an auxiliary device for the production of high-performance tool die steel, which solves the problems that after use, the molten metal remaining at the bottom end of the outer wall of the shunt pipe will condense into blocks, which will seriously block the shunt pipe when severe, and there will be molten metal remaining in the inner wall of the shunt pipe, which will adhere to the inner wall of the shunt pipe after cooling. After long-term use, the inner wall of the shunt pipe will thicken, thus affecting the shunting efficiency. The existing device only simply cleans the outer wall or the inner wall of the shunt pipe, rather than cleaning the inner and outer walls of the shunt pipe in combination, so the cleaning effect on the shunt pipe is not ideal, and thus the shunting efficiency of the shunt pipe is not high. And there are still fine debris and residual dust adsorbed on the inner wall of the shunt pipe after cleaning, so the cleaning effect is not good.

[0005] (II) Technical Solutions To achieve the above objectives, the present invention is realized through the following technical solutions: An auxiliary device for the production of high-performance tool die steel, including a base, on the top of which a lower die is placed, and an upper die is fixedly installed on the top of the lower die. On both sides of the top of the upper die, gate pipes are connected. An outer wall cleaning assembly is sleeved outside the gate pipes. A fixing mechanism is jointly arranged between both sides of the top of the base and the upper die. On the top side of the upper die, a casting box is provided. Inner wall cleaning assemblies are arranged on both sides of the top of the casting box. A first hydraulic rod is jointly arranged between both sides of the casting box and the top of the base. A receiving funnel is fixedly connected to the top of the casting box. On both sides of the bottom of the casting box, shunt pipes are connected. The upper and lower dies are integrally fixed through the fixing mechanism. The first hydraulic cylinder drives the casting box to move downward until the bottom end of the shunt pipe is inserted into the inside of the gate pipe. The molten metal enters the die through the shunt pipe and cools and solidifies. The outer wall cleaning assembly removes the metal solidified into blocks at the bottom end of the outer wall of the shunt pipe, and the inner wall cleaning assembly cleans the inner wall of the shunt pipe, thereby ensuring that the shunt pipe will not be blocked by the remaining molten metal and improving the shunt efficiency of the shunt pipe.

[0006] Preferably, a slide rail is fixedly connected to the top of the base, and a slider is fixedly connected to the back of the casting box. The slider is slidably connected inside the slide rail, ensuring the stability of the operation of the casting box.

[0007] Preferably, the outer wall cleaning assembly includes a collection shell, on the surface of which a placement groove is provided. The gate pipe is located inside the placement groove. A scraping knife is fixedly connected to the top of the collection shell. A scraping plate is jointly fixedly connected between adjacent scraping knives. Through the setting of the outer wall cleaning assembly, the residues on the bottom end of the outer wall of the shunt pipe can be removed, reducing the probability of the shunt pipe being blocked and improving the shunt effect of the shunt pipe.

[0008] Preferably, the inner wall cleaning assembly includes an L-shaped plate fixedly connected to the top of the casting box. A through pipe is fixedly connected to the top of the casting box and is located under the L-shaped plate. A second hydraulic rod is fixedly connected to the bottom of the L-shaped plate, and a motor is fixedly connected to the bottom end of the second hydraulic rod. The output end of the motor is fixedly connected to a rotating cylinder.

[0009] Preferably, a drill bit is fixedly connected to the bottom of the rotating cylinder, and a scraping component is arranged on the outer wall of the rotating cylinder.

[0010] Preferably, a micro air pump is fixedly connected to the top side of the inner part of the rotary cylinder, and an air blowing pipe is fixedly connected to the surface of the rotary cylinder. The inner wall cleaning assembly can clean the residual metal on the inner wall of the shunt pipe. The motor drives the rotary cylinder to rotate, so that the rotating scraping assembly cleans the inner wall of the shunt pipe. The rotating drill bit can drill pores in the thicker positions of the inner wall of the shunt pipe and scrape the residues on the inner wall. The micro air pump blows air into the inner part of the rotary cylinder, and then the air flow blows out towards the inner wall of the shunt pipe through the air blowing pipe, so that the fine debris on the inner wall of the shunt pipe after cleaning can be blown away, improving the cleaning effect of the inner wall of the shunt pipe. The inner wall cleaning assembly can prevent the inner wall of the shunt pipe from thickening due to the condensation of residual molten metal, and improve the shunting efficiency of the shunt pipe.

[0011] Preferably, the scraping assembly includes a scraper. One side of the inner part of the scraper is slidably connected with a connecting plate, and one side of the connecting plate is fixedly connected to the surface of the rotary cylinder. An elastic pressing member is elastically connected between the inner part of the scraper and one side of the connecting plate.

[0012] Preferably, limiting blocks are fixedly connected to both sides of the connecting plate, and limiting grooves are formed in both sides of the inner part of the scraper. The limiting blocks are slidably connected to the inside of the limiting grooves. When the inner wall of the shunt pipe is cleaned by the scraping assembly, the rotation of the rotary cylinder causes the scraper to rotate and scrape the inner wall of the shunt pipe. The setting of the elastic pressing member can make the scraper tightly adhere to the inner wall of the shunt pipe, so that the scraping effect of the scraper is better. Through the setting of the limiting blocks and the limiting grooves, the separation between the connecting plate and the scraper can be prevented.

[0013] Preferably, the fixing mechanism includes a turntable. The turntable is fixedly connected to the top of the base, and guide rods are fixedly connected to both sides of the top of the turntable. The top ends of the two guide rods are fixedly connected together to form a fixing plate.

[0014] Preferably, a threaded rod is rotatably connected to the top of the turntable. The top end of the threaded rod passes through the bottom wall of the fixing plate and is fixedly connected with a handle. The threaded rod is slidably connected to the fixing plate. A pressing plate is threadedly connected to the surface of the threaded rod. The pressing plate is slidably connected to the guide rods. When the whole mold is fixed by the fixing mechanism, the turntable is rotated to make the pressing plate rotate to the side close to the upper mold, and then the handle is rotated to drive the threaded rod to rotate. Due to the limitation of the guide rods, the pressing plate will not rotate by itself, so that the pressing plate moves downward until the pressing plate moves to the surface of the upper mold and presses it tightly, thus achieving the fixing effect on the whole mold and making the device more stable during casting.

[0015] (III) Beneficial effects The present invention provides an auxiliary device for the production of high-performance tool die steel. It has the following beneficial effects: (1). The auxiliary device for producing high-performance tool die steel can rotate and clean the inner wall of the shunt pipe through the scraper in the inner wall cleaning component. The metal blocks on the bottom end of the outer wall can be scraped off by the scraper in the outer wall cleaning component, and the fine debris on the inner wall of the shunt pipe after cleaning can be blown away by the micro air pump, further improving the cleaning effect of the inner wall of the shunt pipe. Therefore, through the combination of the inner wall cleaning component, the outer wall cleaning component and the micro air pump, etc., the inner and outer walls of the shunt pipe can be cleaned, improving the cleaning effect of the shunt pipe and the shunting efficiency of the shunt pipe.

[0016] (2). The auxiliary device for producing high-performance tool die steel can assist in scraping the coagulated blocks scraped off by the scraper through the scraper, improving the cleaning effect of the scraper. And the metal blocks scraped off can be centrally collected through the collecting shell, which is convenient for later recycling and melting, saving the casting cost. And the collecting shell can prevent the scraped metal blocks from flying everywhere, improving the cleanliness of the device during use.

[0017] (3). The auxiliary device for producing high-performance tool die steel rotates the rotating cylinder to make the scraper rotate and scrape the inner wall of the shunt pipe. Through the setting of the elastic tightening member, the scraper can be tightly attached to the inner wall of the shunt pipe, so that the scraping effect of the scraper is better, improving the cleaning effect. Through the setting of the limiting block and the limiting groove, the separation between the connecting plate and the scraper can be prevented, improving the stability of the device.

[0018] (4). The auxiliary device for producing high-performance tool die steel, through the setting of the fixing mechanism, rotates the turntable to make the pressing plate rotate to the side close to the upper die, and then turns the handle to drive the threaded rod to rotate. Due to the limitation of the guide rod, the pressing plate will not rotate by itself, so that the pressing plate moves downward until the pressing plate moves to the surface of the upper die and presses it tightly, thus achieving the fixing effect on the whole die and making the device more stable during casting.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figures 1-10, the present invention provides a technical solution: an auxiliary device for the production of high-performance tool die steel, the structure of which includes a base 1. A lower die 2 is placed on the top of the base 1. An upper die 3 is fixedly installed on the top of the lower die 2. Pouring pipes 4 are connected to both sides of the top of the upper die 3. An outer wall cleaning assembly 5 is sleeved outside the pouring pipes 4. A fixing mechanism 6 is jointly arranged between both sides of the top of the base 1 and the upper die 3. A casting box 7 is arranged on the top side of the upper die 3. Inner wall cleaning assemblies 8 are arranged on both sides of the top of the casting box 7. A first hydraulic rod 9 is jointly arranged between both sides of the casting box 7 and the top of the base 1. A receiving funnel 10 is fixedly connected to the top of the casting box 7. Pouring pipes 11 are connected to both sides of the bottom of the casting box 7. Place the lower die 2 on the base 1, then position the lower die 2 through a positioning plate, and then fix the upper die 3 on the lower die 2 through bolts. Then, fix the upper and lower dies 2 as a whole through the fixing mechanism 6. Drive the casting box 7 to move downward through the first hydraulic cylinder until the bottom end of the pouring pipe 11 is inserted into the inside of the pouring pipe 4. Then, align the discharge port of the casting furnace with the receiving funnel 10, so that the molten metal in the casting furnace enters the inside of the casting box 7 through the receiving funnel 10. The molten metal enters the die through the pouring pipes 11 and cools and solidifies. The first hydraulic rod 9 moves upward and drives the pouring pipes 11 upward, so that the casting box 7 is separated from the die and the mold is opened. After long-term use, the molten metal remaining on the inner wall of the pouring pipe 11 will condense, resulting in the thickening of the inner wall of the pouring pipe 11 and affecting the next pouring efficiency. In addition, the molten metal remaining at the bottom end of the outer wall condenses into blocks and is likely to block the pouring pipe 11. Therefore, the metal blocks condensed at the bottom end of the outer wall of the pouring pipe 11 are removed through the outer wall cleaning assembly 5, and the inner wall of the pouring pipe 11 is cleaned through the inner wall cleaning assembly 8, thereby ensuring that the pouring pipe 11 will not be blocked by the remaining molten metal and improving the pouring efficiency of the pouring pipe 11. The inner wall of the pouring pipe 11 can be rotationally cleaned by the scraper 871 in the inner wall cleaning assembly 8. The metal blocks on the bottom end of the outer wall can be scraped off by the shovel 53 and the scraper 54 in the outer wall cleaning assembly 5. The metal blocks fall into the collection shell 51 for centralized collection and treatment. And through the micro air pump 88, the fine debris on the inner wall of the cleaned pouring pipe 11 can be blown away, further improving the cleaning effect on the inner wall of the pouring pipe 11. Therefore, through the combination of the inner wall cleaning assembly 8, the outer wall cleaning assembly 5 and the micro air pump 88, etc., the inner and outer walls of the pouring pipe 11 can be cleaned, improving the cleaning effect on the pouring pipe 11 and the pouring efficiency of the pouring pipe 11.

[0023] Among them, a slide rail 12 is fixedly connected to the top of the base 1. A slider 13 is fixedly connected to the back of the casting box 7. The slider 13 is slidably connected to the inside of the slide rail 12. While the first hydraulic rod 9 pushes upward against the casting box 7, the slider 13 slides inside the slide rail 12, ensuring the stability of the operation of the casting box 7.

[0024] Among them, the outer wall cleaning component 5 includes a collection shell 51. A placement groove 52 is formed on the surface of the collection shell 51. The gate pipe 4 is located inside the placement groove 52. A scraping blade 53 is fixedly connected to the top of the collection shell 51. A scraping plate 54 is fixedly connected between adjacent scraping blades 53. When the outer wall of the shunt pipe 11 is cleaned by the outer wall cleaning component 5, due to the downward movement of the casting box 7, the shunt pipe 11 also moves downward. When the shunt pipe 11 moves downward, the metal blocks on the bottom end of the outer wall of the shunt pipe 11 are pried up and removed by the scraping blade 53, and the scraping plate 54 can assist in scraping the metal fragments. The scraped metal blocks fall into the collection shell 51 for centralized collection and treatment. Through the setting of the outer wall cleaning component 5, the residues on the bottom end of the outer wall of the shunt pipe 11 can be removed, reducing the probability of the shunt pipe 11 being blocked and improving the shunt effect of the shunt pipe 11.

[0025] Among them, the inner wall cleaning component 8 includes an L-shaped plate 81. The L-shaped plate 81 is fixedly connected to the top of the casting box 7. A through pipe 82 is fixedly connected to the top of the casting box 7. The through pipe 82 is located on the bottom side of the L-shaped plate 81. A second hydraulic rod 83 is fixedly connected to the bottom of the L-shaped plate 81. The bottom end of the second hydraulic rod 83 is fixedly connected to a motor 84. The output end of the motor 84 is fixedly connected to a rotating cylinder 85.

[0026] Among them, a drill bit 86 is fixedly connected to the bottom of the rotating cylinder 85. A scraping component 87 is arranged on the outer wall of the rotating cylinder 85.

[0027] Among them, a micro air pump 88 is fixedly connected to the top side inside the rotating cylinder 85. A blowing pipe 89 is fixedly connected to the surface of the rotating cylinder 85. Through the inner wall cleaning component 8, the metal residues on the inner wall of the shunt pipe 11 can be cleaned. During cleaning, the second hydraulic rod 83 drives the motor 84 to move downward. The motor 84 drives the rotating cylinder 85 to pass through the through pipe 82 and the casting box 7 and enter the inside of the shunt pipe 11. The motor 84 drives the rotating cylinder 85 to rotate, so that the rotating scraping component 87 cleans the inner wall of the shunt pipe 11. The thicker positions on the inner wall of the shunt pipe 11 can be drilled with pores and the inner wall residues can be scraped by the rotating drill bit 86. While cleaning the inner wall of the shunt pipe 11, the micro air pump 88 blows air into the inside of the rotating cylinder 85, and then the air flow blows out to the inner wall of the shunt pipe 11 through the blowing pipe 89, so that the fine debris on the inner wall of the cleaned shunt pipe 11 can be blown away, improving the cleaning effect of the inner wall of the shunt pipe 11. After the inner wall cleaning component 8 cleans the shunt pipe 11, the motor 84 stops working. The second hydraulic rod 83 drives the motor 84 and the rotating cylinder 85 to move upward until they pass through the through pipe 82 and move above the casting box 7.

[0028] Among them, the scraping component 87 includes a scraping blade 871. A connecting plate 872 is slidably connected to the inner side of the scraping blade 871. One side of the connecting plate 872 is fixedly connected to the surface of the rotating cylinder 85. An elastic pressing member 873 is elastically connected between the inside of the scraping blade 871 and one side of the connecting plate 872.

[0029] Among them, two limiting blocks 874 are fixedly connected to both sides of the connecting plate 872. Limiting grooves 875 are formed on both sides of the inside of the scraping blade 871. The limiting blocks 874 are slidably connected to the inside of the limiting grooves 875. When the inner wall of the shunt pipe 11 is cleaned by the scraping component 87, the rotation of the rotating cylinder 85 causes the scraping blade 871 to rotate and scrape the inner wall of the shunt pipe 11. The elastic pressing member 873 can make the scraping blade 871 tightly adhere to the inner wall of the shunt pipe 11, so that the scraping effect of the scraping blade 871 is better. Through the arrangement of the limiting blocks 874 and the limiting grooves 875, the separation between the connecting plate 872 and the scraping blade 871 can be prevented.

[0030] Among them, the fixing mechanism 6 includes a turntable 61. The turntable 61 is fixedly connected to the top of the base 1. Two guide rods 62 are fixedly connected to both sides of the top of the turntable 61. The top ends of the two guide rods 62 are fixedly connected to a fixing plate 63 together.

[0031] Among them, a threaded rod 64 is rotatably connected to the top of the turntable 61. The top end of the threaded rod 64 passes through the bottom wall of the fixing plate 63 and is fixedly connected to a handle 65. The threaded rod 64 is slidably connected to the fixing plate 63. A pressing plate 66 is threadedly connected to the surface of the threaded rod 64. The pressing plate 66 is slidably connected to the guide rods 62. When the whole mold is fixed by the fixing mechanism 6, the turntable 61 is rotated to make the pressing plate 66 rotate to the side close to the upper mold 3, and then the handle 65 is screwed to drive the threaded rod 64 to rotate. Due to the limitation of the guide rods 62, the pressing plate 66 will not rotate by itself, so that the pressing plate 66 moves downward until the pressing plate 66 moves to the surface of the upper mold and presses it tightly, so as to achieve the fixing effect on the whole mold and make the device more stable during casting.

[0032] During operation, place the lower mold 2 on the base 1, then position the lower mold 2 through the positioning plate. After that, fix the upper mold 3 on the lower mold 2 with bolts, and then fix the whole set of the upper and lower molds 2 through the fixing mechanism 6. Drive the casting box 7 to move downward by the first hydraulic cylinder until the bottom end of the shunt pipe 11 is inserted into the inside of the gate pipe 4. Then align the discharge port of the casting furnace with the receiving funnel 10, so that the molten metal in the casting furnace enters the inside of the casting box 7 through the receiving funnel 10. The molten metal enters the mold through the shunt pipe 11 and cools and solidifies. The first hydraulic rod 9 moves upward and drives the shunt pipe 11 upward, causing the separation between the casting box 7 and the mold and opening the mold. Prolonged use will cause the molten metal remaining on the inner wall of the shunt pipe 11 to condense, resulting in the thickening of the inner wall of the shunt pipe 11 and affecting the next shunting efficiency. In addition, the molten metal remaining at the bottom end of the outer wall condenses into blocks and is likely to block the shunt pipe 11. Therefore, the metal blocks condensed at the bottom end of the outer wall of the shunt pipe 11 are removed by the outer wall cleaning assembly 5, and the inner wall of the shunt pipe 11 is cleaned by the inner wall cleaning assembly 8, thus ensuring that the shunt pipe 11 will not be blocked by the remaining molten metal and improving the shunting efficiency of the shunt pipe 11. The inner wall of the shunt pipe 11 can be rotationally cleaned by the scraper 871 in the inner wall cleaning assembly 8. The metal blocks on the bottom end of the outer wall can be scraped off by the shovel 53 and the scraper 54 in the outer wall cleaning assembly 5. The metal blocks fall into the collection shell 51 for centralized collection and treatment. Therefore, through the combination of the inner wall cleaning assembly 8 and the outer wall cleaning assembly 5, the inner and outer walls of the shunt pipe 11 can be cleaned, improving the cleaning effect of the shunt pipe 11 and the shunting efficiency of the shunt pipe 11; When cleaning the bottom end of the outer wall of the shunt pipe 11 by the outer wall cleaning assembly 5, due to the downward movement of the casting box 7, the shunt pipe 11 also moves downward. When the shunt pipe 11 moves downward, the metal blocks on the bottom end of the outer wall of the shunt pipe 11 are pried up and removed by the shovel 53, and the scraper 54 can assist in scraping the metal fragments. The shoveled metal blocks fall into the collection shell 51 for centralized collection and treatment. Through the setting of the outer wall cleaning assembly 5, the residues on the bottom end of the outer wall of the shunt pipe 11 can be removed, reducing the probability of the shunt pipe 11 being blocked and improving the shunting effect of the shunt pipe 11; The inner wall cleaning component 8 can clean the metal residues on the inner wall of the shunt pipe 11. During cleaning, the second hydraulic rod 83 drives the motor 84 to move downward. The motor 84 drives the rotating cylinder 85 to pass through the through pipe 82 and the casting box 7 and enter the inside of the shunt pipe 11. The motor 84 drives the rotating cylinder 85 to rotate, so that the rotating scraping component 87 cleans the inner wall of the shunt pipe 11. The rotating drill bit 86 can drill pores in the thicker positions on the inner wall of the shunt pipe 11 and scrape off the residues on the inner wall. While cleaning the inner wall of the shunt pipe 11, the micro air pump 88 blows air into the inside of the rotating cylinder 85, and then the air flow blows out through the air blowing pipe 89 to the inner wall of the shunt pipe 11, so that the fine debris on the inner wall of the cleaned shunt pipe 11 can be blown away, improving the cleaning effect of the inner wall of the shunt pipe 11. After the inner wall cleaning component 8 cleans the shunt pipe 11, the motor 84 stops working. The second hydraulic rod 83 drives the motor 84 and the rotating cylinder 85 to move upward until they pass through the through pipe 82 and move above the casting box 7. The rotation of the rotating cylinder 85 causes the scraper 871 to rotate and scrape the inner wall of the shunt pipe 11. The setting of the elastic pressing member 873 can make the scraper 871 closely adhere to the inner wall of the shunt pipe 11, so that the scraping effect of the scraper 871 is better. The setting of the limit block 874 and the limit groove 875 can prevent the separation between the connecting plate 872 and the scraper 871.
