Description

Technical Field

[0001] The invention relates to the technical field of metal casting processing, in particular to a metal casting processing pouring device that prevents the generation of air holes. Background Art

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

[0003] For example, the casting pouring device and casting molding process disclosed in CN114433826B, when using the device for pouring, the pouring box can be tilted so that the internal mold is also kept in an inclined state, so that the degree of splashing generated when the molten iron is poured into the mold is relatively small, thereby greatly reducing the pit-shaped pores left on the surface of the casting after molding, and correspondingly reducing the defects on the surface of the molded casting; in the molding process method, the casting is processed by tilting the pouring box and the vertical molding process, so that the casting can not only reduce the surface defects after molding, but also ensure that its own structure has sufficient strength to meet the standards. However, in actual use, by tilting the pouring box, the mold can be tilted for pouring to reduce the defects on the surface of the casting. Different types of workpieces have different tilt angles during tilt pouring. For castings with complex shapes, deep cavities or dead corners, appropriately increasing the tilt angle can make the molten metal better fill these parts, but for some flat and simple castings, the tilt angle It should not be too large to prevent the molten metal from flowing too fast and generating eddies and gas entrapment, which makes it inconvenient to adjust the inclination angle of the mold. Moreover, due to the inclined setting of the mold, it is difficult for the poured molten metal to be evenly filled in the interior of the mold, which may easily lead to inconsistent cooling of various positions of the casting during the subsequent cooling process of the metal, and may easily lead to thermal stress inside the casting, affecting the processing quality. Therefore, after the casting is completed, the mold needs to be straightened for subsequent cooling and molding. When straightening the mold, it is necessary to straighten the mold manually. After the mold is straightened, the internal molten metal level will shake to a certain extent, which may cause the surface of the casting that has been initially solidified to change, affecting the processing quality of the casting. Moreover, when the mold is rotated from tilt to perpendicular to the horizontal plane, the molten metal level remains horizontal. There will be residues on the surface of the molten metal in contact with one side of the inner wall of the mold, which will cause waste of molten metal and is not convenient for later separation, affecting the processing quality. There are certain usage defects.

[0004] Therefore, we propose a metal casting processing and pouring device for preventing pore generation in order to solve the problems raised above. Summary of the Invention

[0028] Compared with the prior art, the present invention has the following beneficial effects: the metal casting processing and pouring device for preventing the formation of air holes allows the mold to remain tilted during the pouring process of the metal casting, and the side of the mold can gradually rotate perpendicular to the horizontal plane during the pouring process. The tilt angle of the mold can be adjusted according to the type of metal casting, thereby avoiding affecting the processing quality of the casting after the pouring is completed, thereby improving practicality;

[0029] 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 the mold, and then start the hydraulic push rod to drive the moving plate to move. After the moving plate moves, the mounting rod can be pulled up by the vertical rod to make the movable block slide on the fixed rod, and then the rotating seat can be rotated to a suitable angle, and then the mold can be poured with molten metal. During the pouring process, the metal liquid level inside the mold continues to rise. By tilting the pouring, splashing can be reduced, and the entry of air can be reduced, and the formation of pores can be reduced. During the pouring process, the hydraulic push rod drives the movable plate to move downward slowly. The descending speed can be adjusted according to the pouring speed, so that the rotating seat can be driven to rotate downward, thereby making the mold tilt angle gradually smaller. After the pouring is completed, the side of the mold can be perpendicular to the horizontal plane, which is convenient for the subsequent cooling and molding of the molten metal. The pouring assembly allows the mold to remain tilted during the pouring process, and the side of the mold can gradually rotate perpendicular to the horizontal plane during the pouring process. The tilt angle of the mold can be adjusted according to the type of metal casting to avoid affecting the processing quality of the casting after the pouring is completed, thereby improving practicality.

[0030] 2. Before pouring into the mold, the screw rod 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, so that the left and right positions of the pouring tube can be adjusted, and the mold is fixed so that the pouring gate 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 down, so that the pouring position of the pouring tube is above the pouring gate. After the mold is rotated, the position of the pouring gate will also change. At this time, the movement of the movable plate can be achieved by pulling the connecting frame with 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, so that the position of the pouring tube changes during the rotation of the mold, and the pouring tube is prevented from being away from the pouring gate and affecting the pouring work.

[0031] 3. During the pouring process, the rotating seat rotates. After the rotating seat rotates, the rotating gear and the rotating seat rotate on the same axis. The rotating gear can drive the rotating shaft to rotate by meshing with the teeth. After the rotating shaft rotates, the rotating rod can be driven to rotate by the connection between the first pulley and the second pulley. The rotating rod changes with the moving position of the positioning plate. During the rotation process, the rotating rod makes the belt at the connection between the first pulley and the second pulley continuously straighten, which can push the moving rod to move and stretch the support spring. The belt at the connection between the first pulley and the second pulley can be tensioned by the tensioning pulley. After the rotating rod rotates, it can drive the two sets of U-shaped frames to rotate, thereby allowing the striking block to rotate and strike the mold. During the striking process, the sliding rod can move to stretch the reset spring. Two sets of striking blocks and rotating shafts can also be set on both positioning plates, and a connecting transmission structure is set between the two rotating shafts. Then, as the mold rotates during the pouring process, the mold can be struck, causing the mold to vibrate. It can be used for molds of different sizes, can assist in the discharge of air in the molten metal, can further prevent the formation of air holes in the casting, and improve the processing quality.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] See also Figures 1-9 The present invention provides a technical solution: a metal casting processing and pouring device for preventing the generation of pores, comprising a base 1, two groups of columns 101 are symmetrically installed on the top of the base 1, and a fixing plate 102 is fixedly installed on the top of the two groups of columns 101;

[0044] Also includes:

[0046] The rotating seat 201 is hinged on one side of the top of the base 1. Threaded rods 202 are symmetrically threaded on the upper sides of the inner side of the rotating seat 201. One end of the threaded rod 202 is rotatably connected to a positioning plate 203. A guide rod 204 is fixedly installed on one side of the positioning plate 203 below the threaded rod 202. The guide rod 204 is slidably connected to the rotating seat 201. A mounting plate 205 is fixedly installed on the lower side of the rotating seat 201.

[0047] The fixed blocks 206 are symmetrically mounted on the top of the mounting plate 205. A fixed rod 207 is fixedly mounted between each set of two fixed blocks 206. The outer portions of the two fixed rods 207 are slidably connected to movable blocks 208. A mounting rod 209 is fixedly mounted between the two movable blocks 208. The outer portions of the mounting rods 209 are symmetrically rotatably connected to rotating blocks 210. A vertical rod 211 is fixedly mounted on the tops of the two rotating blocks 210.

[0048] A hydraulic push rod 212 is fixedly installed on one side of the top of the fixed plate 102, and the movable end of the hydraulic push rod 212 passes through the fixed plate 102 and is fixedly installed with a movable plate 213, and a limiting rod 214 is fixedly installed on one side of the top of the movable plate 213. At the same time, the limiting rod 214 is slidably connected to the fixed plate 102, and the top ends of the two vertical rods 211 are fixedly connected to the movable plate 213.

[0049] Example 1: Figure 1-Figure 5As shown, when pouring the mold, the mold is placed inside the rotating seat 201, and then the threaded rod 202 can be rotated to drive the positioning plate 203 to move, so that the two positioning plates 203 clamp the mold, and then the hydraulic push rod 212 can be started to drive the movable plate 213 to move. After the movable plate 213 moves, the mounting rod 209 can be pulled up by the vertical rod 211, so that the movable block 208 slides on the fixed rod 207, and then the rotating seat 201 can be rotated to a suitable angle, and then the mold can be poured with molten metal. During the pouring process, the metal liquid level inside the mold continues to rise. By tilting the pouring, splashing can be reduced, and then the entry of air can be reduced, and the formation of pores can be reduced. During the pouring process, the hydraulic push rod 212 drives the movable plate 213 to slowly move. The descent speed can be adjusted according to the pouring speed, so that the rotating seat 201 can be driven to rotate downward, and 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 the pouring is completed, which is convenient for the subsequent cooling and molding of the molten metal, and the angle of the mold is inconvenient to reduce during the pouring process. As the molten metal level rises, the molten metal attached to the inner wall of the mold when it is tilted can be covered, which can avoid the molten metal remaining on the inner wall of the mold after the mold is tilted and straightened. The pouring assembly 2 can keep the mold tilted during the pouring process, and the side of the mold can gradually rotate perpendicular to the horizontal plane during the pouring process. The inclination angle of the mold can be adjusted according to the type of metal casting to avoid affecting the processing quality of the casting after the pouring is completed, thereby improving practicality.

The movable end of the electric push rod 2181 passes through the movable frame 218 and is fixedly connected to the mounting frame 220.

[0052] A screw rod 221 is rotatably connected to the lower side of the mounting frame 220, and a connecting frame 222 is threadedly connected to the outer side of the screw rod 221, and a support rod 223 is slidably connected to the inside of the connecting frame 222 below the screw rod 221. At the same time, the support rod 223 is fixedly connected to the mounting frame 220, and a steel wire rope 224 is fixedly installed on the side of the connecting frame 222 away from the mounting frame 220, and the end of the steel wire rope 224 away from the connecting frame 222 is fixedly connected to the movable plate 213.

[0053] Example 2: Figures 1-4 and Figure 6-Figure 7 As shown, before pouring into 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 tube 216 can be adjusted, and when the mold is fixed, the pouring port and the pouring tube 216 are in the same straight line, and then the electric push rod 2181 can be started to drive the pouring tube 216 to move downward, so that the pouring position of the pouring tube 216 is located above the pouring port, and then the position of the pouring port will change after the mold is rotated. At this time, the movement of the movable plate 213 can be achieved by pulling the connecting frame 222 to move through the wire rope 224, and the mounting frame 220 can be pulled to move, so that the pouring tube 216 moves with the rotation of the mold, so that the position of the pouring tube 216 changes during the rotation of the mold, thereby avoiding the pouring tube 216 being away from the pouring port and affecting the pouring work.

It can be used for molds of different sizes, can assist in the discharge of air in the molten metal, can further prevent the formation of pores in the casting, and improve the processing quality.

[0060] Working principle: When using the anti-porosity metal casting processing pouring device, first, according to Figures 1-9As shown, when pouring the mold, the mold is placed inside the rotating seat 201, and then the threaded rod 202 can be rotated to drive the positioning plate 203 to move, so that the two positioning plates 203 clamp the mold, and then the hydraulic push rod 212 can be started to drive the movable plate 213 to move. After the movable plate 213 moves, the mounting rod 209 can be pulled up by the vertical rod 211, so that the movable block 208 slides on the fixed rod 207, and then the rotating seat 201 can be rotated to a suitable angle, and then the mold can be poured with molten metal. During the pouring process, the metal liquid level inside the mold continues to rise. By tilting the pouring, splashing can be reduced, and the entry of air can be reduced, and the formation of pores can be reduced. During the pouring process, the hydraulic push rod 212 drives the movable plate 213 to move slowly downward. The descending speed can be adjusted according to the pouring speed, so that the rotating seat 201 can be driven to rotate downward, and the tilt angle of the mold can be continuously reduced, so that after the pouring is completed, the side of the mold can be perpendicular to the horizontal plane, which is convenient for the subsequent cooling and molding of the molten metal.

[0061] Before pouring into 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 tube 216 can be adjusted. When the mold is fixed, the pouring port and the pouring tube 216 are in the same straight line. Then, the electric push rod 2181 can be started to drive the pouring tube 216 to move downward, so that the pouring position of the pouring tube 216 is above the pouring port. After the mold is rotated, the position of the pouring port will also change.
