Description

Technical Field

[0001] The present invention relates to the technical field of metal casting processing, and specifically relates to a pouring device for metal casting processing to prevent the generation of air holes. Background Technique

[0002] Metal casting pouring is a process of pouring molten metal into a pre-prepared mold to solidify it into a part or workpiece of the desired shape.

[0003] For example, in the casting pouring device and pouring molding process with the publication number CN114433826B, when using this device for pouring, the pouring box can be tilted so that the internal mold also remains tilted. In this way, the sputtering degree generated when the molten iron is poured into the mold is relatively small, so that the pit-shaped air holes left on the surface of the casting after forming can be reduced to a great extent, and correspondingly, the surface defects of the formed casting can be reduced; in the molding process method, through the process idea of tilted pouring and vertical molding, the casting can not only reduce the surface defects after molding, but also ensure that its own structure has sufficient strength meeting the standards. However, in actual use, by tilting the pouring box, the mold can be tilted for pouring to reduce the surface defects of the casting. Different types of workpieces have different tilting angles during tilted pouring. For castings with complex shapes, deep cavities or dead corners, appropriately increasing the tilting angle can make the molten metal better fill these parts. However, for some flat and simple castings, the tilting angle should not be too large to avoid the generation of eddies and gas entrainment due to the too fast flow rate of the molten metal, which is not convenient for adjusting the tilting angle of the mold. And because the mold is tilted, it is very difficult for the poured molten metal to evenly fill the inside of the mold, which easily leads to inconsistent cooling at each position of the casting during the subsequent cooling process, easily causes thermal stress inside the casting, and affects the processing quality. Therefore, after pouring the casting, the mold needs to be righted for subsequent cooling and forming. When righting the mold, the mold needs to be manually righted. After the mold is righted, the liquid level of the molten metal inside will shake to a certain extent, which may change the surface of the casting that has been initially solidified, affecting the processing quality of the casting. And when the mold rotates from tilted to perpendicular to the horizontal plane, the metal liquid level always remains horizontal, and residues will adhere to the mold on the surface of the molten metal in contact with one side of the mold inner wall, which will cause waste of molten metal and is not convenient for subsequent detachment, affecting the processing quality, and there are certain usage defects.

[0004] Therefore, we propose a pouring device for metal casting processing to prevent the generation of air holes to facilitate solving the problems raised above. Summary of the Invention

When righting the mold, it is necessary to manually right the mold. After the mold is righted, the liquid level of the molten metal inside will shake to a certain extent, which may change the surface of the casting that has initially solidified, affecting the processing quality of the casting. Moreover, when the mold rotates from an inclined position to be perpendicular to the horizontal plane, the metal liquid level always remains horizontal, and residues will adhere to the mold on the surface of the molten metal in contact with one side of the mold inner wall, resulting in waste of molten metal and inconvenience for later detachment, affecting the processing quality.

[0023] Compared with the prior art, the beneficial effect of the present invention is that in the pouring device for processing metal castings to prevent the generation of air holes, during the pouring process of the metal castings, the mold can be kept inclined during the pouring process, and the side of the mold can gradually rotate perpendicular to the horizontal plane during the pouring process, and the inclination angle of the mold can be adjusted according to the type of the metal casting, avoiding affecting the processing quality of the casting after pouring, and improving the practicability. 1. When pouring the mold, place the mold inside the rotating seat. Then, rotate the threaded rod to drive the positioning plate to move, so that the two positioning plates clamp and fix the mold. Then, start the hydraulic push rod to drive the moving plate to move. After the moving plate moves, it can pull the mounting rod upward through the vertical rod, so that the movable block slides on the fixed rod, and then the rotating seat can be rotated to an appropriate angle. Then, pour the molten metal into the mold. During the pouring process, the metal liquid level inside the mold continuously rises. By pouring obliquely, splashing can be reduced, and thus the entry of air can be reduced, and the generation of air holes can be reduced. During the pouring process, drive the moving plate to slowly move downward through the hydraulic push rod, and the descending speed can be adjusted according to the pouring speed, so that the rotating seat can be driven to rotate downward, and then the inclination angle of the mold can be continuously reduced, so that the side of the mold can be perpendicular to the horizontal plane after pouring, which is convenient for the subsequent cooling and forming of the molten metal. Through the pouring component, the mold can be kept inclined during the pouring process, and the side of the mold can gradually rotate perpendicular to the horizontal plane during the pouring process, and the inclination angle of the mold can be adjusted according to the type of the metal casting, avoiding affecting the processing quality of the casting after pouring, and improving the practicability. 2. Before pouring the mold, the screw can be rotated to drive the mounting frame to move, so that the movable frame slides on the positioning rod and stretches the telescopic spring, enabling the left and right positions of the pouring tube to be adjusted. When the mold is fixed, the pouring port and the pouring tube are in the same straight line. Then, the electric push rod can be started to drive the pouring tube to move downwards, so that the pouring position of the pouring tube is above the pouring port. After the mold rotates, the position of the pouring port will also change. At this time, the movement of the moving plate can drive the connecting frame to move through the steel wire rope, and the mounting frame can be pulled to move, so that the pouring tube moves with the rotation of the mold, and the position of the pouring tube changes during the rotation of the mold, avoiding the pouring tube moving away from the pouring port and affecting the pouring operation; 3. During the pouring process, the rotating seat rotates. After the rotating seat rotates, the rotating gear rotates coaxially with the rotating seat. The rotating gear can drive the rotating shaft to rotate through the engagement with the teeth. After the rotating shaft rotates, the rotating rod can be driven to rotate through the connection between the first belt pulley and the second belt pulley. The position of the rotating rod changes with the movement of the positioning plate. During the rotation of the rotating rod, the belt at the connection between the first belt pulley and the second belt pulley is continuously straightened, which can push the moving rod to move and stretch the support spring. The belt at the connection between the first belt pulley and the second belt pulley can be tensioned by the tensioning wheel. After the rotating rod rotates, it can drive two U-shaped frames to rotate, and then the knocking block can be driven to knock the mold. During the knocking process, the sliding rod can be moved to stretch the return spring. Two groups of knocking blocks and rotating shafts can also be set on both positioning plates, and a connection transmission structure can be set between the two rotating shafts. Then, during the pouring process, the mold can be knocked as the mold rotates, causing the mold to vibrate, and it can be used for molds of different sizes, which can assist in discharging the air in the molten metal and further prevent pores from being generated in the casting, improving the processing quality.

[0026] 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.

[0027] Please refer to Figures 1 - 9 , the present invention provides a technical solution: a metal casting processing and pouring device for preventing air holes from being generated, including a base 1, two groups of columns 101 are symmetrically installed on the top of the base 1, and a fixed plate 102 is fixedly installed on the top of the two groups of columns 101; It further includes: Pouring component 2, arranged above the base 1, and the pouring component 2 includes a rotating seat 201; Rotating seat 201, hinged on one side of the top of the base 1, the upper sides of both sides inside the rotating seat 201 are symmetrically threadedly connected with threaded rods 202, one end of the threaded rod 202 is rotatably connected with a positioning plate 203, and a guide rod 204 is fixedly installed on one side of the positioning plate 203 below the threaded rod 202. At the same time, the guide rod 204 is slidably connected with the rotating seat 201, and a mounting plate 205 is fixedly installed below one side of the rotating seat 201; The fixed blocks 206 are symmetrically installed at the top of the mounting plate 205. A fixed rod 207 is fixedly installed between each group of two fixed blocks 206. The outer parts of the two fixed rods 207 are both slidably connected with movable blocks 208. An installation rod 209 is fixedly installed between the two movable blocks 208. At the same time, the outer part of the installation rod 209 is symmetrically and rotatably connected with rotating blocks 210. Moreover, vertical rods 211 are fixedly installed at the tops of the two rotating blocks 210; One side of the top of the fixed plate 102 is fixedly installed with a hydraulic push rod 212. The movable end of the hydraulic push rod 212 passes through the fixed plate 102 and is fixedly installed with a moving plate 213. One side of the top of the moving plate 213 is fixedly installed with a limiting rod 214. At the same time, the limiting rod 214 is slidably connected with the fixed plate 102. Moreover, the tops of the two vertical rods 211 are fixedly connected with the moving plate 213.

[0028] Embodiment 1: As Figures 1 - 5 shown, when pouring the mold, place the mold inside the rotating seat 201. Then, rotate the threaded rod 202 to drive the positioning plate 203 to move, so that the two positioning plates 203 clamp and fix the mold. Then, start the hydraulic push rod 212 to drive the moving plate 213 to move. After the moving plate 213 moves, it can pull the installation rod 209 to move upward through the vertical rod 211, so that the movable block 208 slides on the fixed rod 207. Furthermore, the rotating seat 201 can be rotated to a suitable angle. Then, pour the molten metal into the mold. During the pouring process, the molten metal level inside the mold continuously rises. By pouring obliquely, splashing can be reduced, and thus the entry of air can be reduced, and the generation of pores can be reduced. During the pouring process, drive the moving plate 213 to slowly move downward through the hydraulic push rod 212. The descending speed can be adjusted according to the pouring speed, so that the rotating seat 201 can be driven to rotate downward. Furthermore, the inclination angle of the mold can be continuously reduced, so that the side of the mold can be perpendicular to the horizontal plane after pouring is completed, which is convenient for the subsequent cooling and forming of the molten metal. And during the pouring process, the angle of the mold is not reduced. As the molten metal level rises, the molten metal adhering to the inner wall of the mold during tilting can be covered, which can avoid the molten metal remaining on the inner wall of the mold after the mold is tilted and poured and then righted. Through the pouring assembly 2, the mold can be kept tilted during the pouring process, and the side of the mold can gradually rotate perpendicular to the horizontal plane during the pouring process. And the inclination angle of the mold can be adjusted according to the type of metal casting, so as to avoid affecting the processing quality of the casting after pouring is completed, and the practicability is improved.

[0029] On the other side of the top of the fixing plate 102, an installation groove 215 is penetrated and opened. On one side inside the installation groove 215, positioning rods 217 are symmetrically installed. A movable frame 218 is slidably connected to the outside of the two positioning rods 217. At the same time, on the outside of the two positioning rods 217 and on one side of the movable frame 218, telescopic springs 219 are sleeved. The two ends of the telescopic spring 219 are respectively fixedly connected to the installation groove 215 and the movable frame 218; On one side of the movable frame 218, a pouring pipe 216 is arranged. An installation frame 220 is fixedly installed on the outside of the pouring pipe 216. On one side of the top of the movable frame 218, an electric push rod 2181 is fixedly installed. The movable end of the electric push rod 2181 passes through the movable frame 218 and is fixedly connected to the installation frame 220; Below one side of the installation frame 220, a screw rod 221 is rotatably connected. On one side of the outside of the screw rod 221, a connecting frame 222 is threadedly connected. Inside the connecting frame 222 and below the screw rod 221, a support rod 223 is slidably connected. The support rod 223 is fixedly connected to the installation frame 220. On the side of the connecting frame 222 away from the installation frame 220, a steel wire rope 224 is fixedly installed. One end of the steel wire rope 224 away from the connecting frame 222 is fixedly connected to the moving plate 213.

[0030] Embodiment 2: As Figures 1 - 4 and Figures 6 - 7 shown, before pouring the mold, the screw rod 221 can be rotated to drive the installation frame 220 to move, so that the movable frame 218 slides on the positioning rod 217 and stretches the telescopic spring 219, so that the left and right positions of the pouring pipe 216 can be adjusted. When the mold is fixed, the pouring port and the pouring pipe 216 are on the same straight line. Then, the electric push rod 2181 can be started to drive the pouring pipe 216 to move downwards, so that the pouring position of the pouring pipe 216 is above the pouring port. After the mold rotates, the position of the pouring port will also change. At this time, the movement of the moving plate 213 can pull the connecting frame 222 to move through the steel wire rope 224, and the installation frame 220 can be pulled to move, so that the pouring pipe 216 moves with the rotation of the mold, so that the position of the pouring pipe 216 changes during the rotation of the mold, avoiding the pouring pipe 216 moving away from the pouring port and affecting the pouring work.

[0031] The defoaming assembly 3 is arranged on one side inside the rotating seat 201; The defoaming assembly 3 includes positioning blocks 301 symmetrically installed on one side of the side positioning plate 203. A rotating rod 302 is rotatably connected inside the two positioning blocks 301. Rotating members 303 are fixedly installed on one side of the two positioning blocks 301 outside the rotating rod 302. At the same time, two groups of U-shaped frames 304 are symmetrically installed on the outer sides of the rotating members 303. Slide rods 305 are slidably connected inside the two groups of U-shaped frames 304. A knocking block 307 is fixedly installed at one end of the slide rod 305. A return spring 306 is sleeved on one side of the outer part of the slide rod 305. The two ends of the return spring 306 are fixedly connected to the slide rod 305 and the U-shaped frame 304 respectively; An installation block 308 is fixedly installed on one side inside the rotating seat 201. A rotating shaft 309 is rotatably connected inside the installation block 308. A rotating gear 310 is fixedly installed at one end of the rotating shaft 309. At the same time, an arc-shaped frame 312 is fixedly installed on one side of the top of the base 1 where the rotating seat 201 is located. A number of teeth 311 are fixedly installed on one side of the arc-shaped frame 312. The rotating gear 310 is meshed with the teeth 311. The axis of the arc-shaped frame 312 coincides with the rotation axis of the rotating seat 201; A second pulley 314 is fixedly installed at one end of the rotating rod 302. One end of the rotating shaft 309 passes through the installation block 308 and a first pulley 313 is fixedly installed. The first pulley 313 is rotationally connected to the second pulley 314 through a belt; Moving rods 315 are symmetrically slidably connected on one side inside the rotating seat 201 where the installation block 308 is located. Support springs 318 are sleeved on one side of the outer parts of the two moving rods 315. The two ends of the support springs 318 are fixedly connected to the moving rods 315 and the rotating seat 201 respectively. At the same time, a moving frame 316 is fixedly installed at one end of the two moving rods 315. A tension pulley 317 is rotatably connected to the inner side of the moving frame 316. The tension pulley 317 is rotationally connected to the belt at the connection of the first pulley 313 and the second pulley 314.

[0032] Embodiment 3: As Figures 1 - 4 and Figures 8 - 9As shown, during the pouring process, the rotating seat 201 rotates. After the rotating seat 201 rotates, the rotating gear 310 rotates coaxially with the rotating seat 201. The rotating gear 310 can drive the rotating shaft 309 to rotate through meshing with the teeth 311. After the rotating shaft 309 rotates, it can drive the rotating rod 302 to rotate through the connection between the first belt pulley 313 and the second belt pulley 314. The position of the rotating rod 302 changes as the positioning plate 203 moves. When the positioning plate 203 fixes the mold, its position will move. The moving rod 315 is inserted through the rotating seat 201. The belt at the connection between the first belt pulley 313 and the second belt pulley 314 is in a bent state and in close contact with the tension pulley 317 in the initial state. After the positioning plate 203 moves, it drives the position of the rotating rod 302 to change, causing the second belt pulley 314 to move away from the first belt pulley 313. At this time, the belt at the connection between the first belt pulley 313 and the second belt pulley 314 is pulled. During the rotation of the rotating rod 302, the belt at the connection between the first belt pulley 313 and the second belt pulley 314 is continuously straightened. The straightened belt can push the tension pulley 317 to move, can push the moving rod 315 to move and stretch the support spring 318, and can act on the tension pulley 317 through the reaction force after the support spring 318 is stretched. The tension pulley 317 can tighten the belt between the first belt pulley 313 and the second belt pulley 314. After the rotating rod 302 rotates, it can drive two groups of U-shaped frames 304 to rotate, and then can make the knocking block 307 rotate to knock the mold. During the knocking process, the sliding rod 305 can move to stretch the return spring 306. Also, two groups of knocking blocks 307 and rotating shafts 309 can be provided on both positioning plates 203, and a connection transmission structure can be provided between the two rotating shafts 309. Then, during the pouring process, as the mold rotates, the mold can be knocked, causing the mold to vibrate, and it can be used for molds of different sizes, which can assist in discharging the air in the molten metal and can further prevent pores from being generated in the casting, improving the processing quality.

[0033] Working principle: When using the metal casting processing and pouring device for preventing pore generation, first, according to Figures 1 - 9As shown, when pouring the mold, place the mold inside the rotating seat 201. Then, rotate the threaded rod 202 to drive the positioning plate 203 to move, so that the two positioning plates 203 clamp and fix the mold. After that, start the hydraulic push rod 212 to drive the moving plate 213 to move. After the moving plate 213 moves, it can pull the mounting rod 209 upward through the vertical rod 211, causing the movable block 208 to slide on the fixed rod 207, thereby enabling the rotating seat 201 to rotate to an appropriate angle. Then, pour the molten metal into the mold. During the pouring process, the metal liquid level inside the mold continuously rises. By tilting the pouring, splashing can be reduced, and thus the entry of air can be reduced, and the generation of pores can be decreased. During the pouring process, drive the moving plate 213 to slowly move downward through the hydraulic push rod 212. The descending speed can be adjusted according to the pouring speed, so as to drive the rotating seat 201 to rotate downward, thereby making the tilt angle of the mold continuously decrease, so that the side of the mold can be perpendicular to the horizontal plane after pouring, which is convenient for the subsequent cooling and forming of the molten metal; Before pouring the mold, the screw 221 can be rotated to drive the mounting frame 220 to move, so that the movable frame 218 slides on the positioning rod 217 and stretches the telescopic spring 219, so that the left and right positions of the pouring pipe 216 can be adjusted, and when the mold is fixed, the pouring port and the pouring pipe 216 are in the same straight line. Then, the electric push rod 2181 can be started to drive the pouring pipe 216 to move downwards, so that the pouring position of the pouring pipe 216 is above the pouring port. After the mold rotates, the position of the pouring port will also change. At this time, the movement of the moving plate 213 can pull the connecting frame 222 to move through the steel wire rope 224, and the mounting frame 220 can be pulled to move, so that the pouring pipe 216 moves with the rotation of the mold, so that the position of the pouring pipe 216 changes during the rotation of the mold. During the pouring process, the rotating seat 201 rotates. After the rotating seat 201 rotates, the rotating gear 310 rotates coaxially with the rotating seat 201. The rotating gear 310 can drive the rotating shaft 309 to rotate through the engagement with the teeth 311. After the rotating shaft 309 rotates, it can drive the rotating rod 302 to rotate through the connection between the first belt pulley 313 and the second belt pulley 314. The position of the rotating rod 302 changes with the movement of the positioning plate 203.
