Description

Technical Field

[0001] The invention relates to the technical field of cast iron casting and molding, in particular to ductile iron casting and molding equipment. Background Art

[0002] Ductile iron casting equipment is a complete set of equipment specially used to produce ductile iron castings. Its core goal is to obtain castings with spheroidal graphite, high strength, high toughness and good wear resistance by precisely controlling the melting, spheroidizing, pouring, cooling and other process links.

[0003] During the sand filling process of large ductile iron casting molding equipment, workers need to hold the sand injection pipe and adjust its position so that the opening is aligned with the sand injection part on the top of the sand box; however, due to the large size of the metal model, workers cannot complete the operation in a single position and need to repeatedly adjust their body position and posture. This is not only a cumbersome process, but also seriously affects work efficiency. At the same time, workers need to maintain postures such as bending over and raising their arms for a long time during the operation. Especially when handling large models, the posture lasts longer, which can easily lead to muscle fatigue and further reduce work efficiency and operation accuracy. When injecting molten iron into the sand mold, workers need to adjust their body position and posture repeatedly, which is not only cumbersome, but also seriously affects work efficiency. During the process, it is crucial to stably control the speed at which molten iron is poured in. However, since the container for the molten iron is very large, it is difficult to accurately control the rotation speed by manually rotating the pouring bucket to tilt it and pour out the molten iron. If the tilting speed is too fast, the molten iron will flow out quickly and draw in air to form pores, and will also wash away the sand mold to form sand inclusions, which will not only reduce the quality of the casting, but also put the workers too close to the molten iron and pose a safety risk of being scalded. If the speed is too slow, more oxide film will be produced on the surface of the molten iron, resulting in the molten iron not being able to flow out evenly. Therefore, the present application provides a ductile iron casting and molding equipment to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a ductile iron casting molding equipment. By setting a position adjustment mechanism and an angle adjustment mechanism, the staff can quickly complete the sand injection work by simply standing at a work station on one side of the sand box body, thereby reducing labor intensity and significantly improving the sand injection efficiency. The above settings can solve the problem of inconvenience in manual operation in the existing large-scale equipment production casting process.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A ductile iron casting molding equipment includes an operating table, a sand box body is provided on the operating table, a hanger is provided on the top of the sand box body, a pouring ladle body is provided at the bottom of the hanger, a sand supply mechanism is provided on the top of the sand box body, and a sand outlet pipe is installed on one side of the sand supply mechanism; a position adjustment mechanism, the position adjustment mechanism is used to adjust the position of the opening of the sand outlet pipe, the position adjustment mechanism is connected to the sand supply mechanism; the angle adjustment mechanism is used to adjust the inclination angle of the pouring ladle body, and the angle adjustment mechanism is connected to the position adjustment mechanism.

[0006] Optionally, the position adjustment mechanism includes a first skeleton installed at the bottom of the sand supply mechanism, a second skeleton is fixedly connected to a side of the first skeleton close to the sand outlet pipe, an end of the second skeleton away from the first skeleton is fixedly connected to a first connecting block, a first connecting frame is installed at the bottom of the first skeleton, a rotating block is rotatably connected to the first connecting frame, handles are fixedly connected to both sides of the rotating block, a first connecting rope is installed at the bottom of the second skeleton, and an end of the first connecting rope close to the second skeleton is fixedly connected to a third connecting block.

[0007] Optionally, both sides of the second skeleton are fixedly connected to the third skeleton, and the second skeleton and the third skeleton form an integrated structure.

[0008] Optionally, a first weakened portion is provided on the top of the second frame, and the second frame is made of plastic material.

[0009] Optionally, the first connecting frame is hook-shaped, and one end of the first connecting frame away from the first skeleton is fixedly connected to a limiting plate.

[0010] Optionally, the surface of the rotating block is provided with threads, the outer wall of the handle is provided with anti-slip grooves, and the handle is provided with a plurality of concave portions and convex points at equal intervals in a ring shape.

[0011] Optionally, the second frame and the third frame are both arc-shaped structures protruding toward the top, and the first frame is cross-shaped.

[0012] Optionally, the angle adjustment mechanism includes a second connecting frame mounted on the first skeleton, a pulley is rotatably connected to the second connecting frame, a second connecting rope is provided at the bottom of the pulley, and the second connecting rope is fixedly connected to a second connecting block at one end close to the pouring bucket body, and a turning handle is installed on the side of the pouring bucket body close to the second connecting block.

[0013] Optionally, the shape of the second connecting block is adapted to the shape of the handle, and the second connecting block is made of stainless steel.

[0014] Optionally, a guide portion is provided on one side of the second connecting block, and a second weakened portion is provided on a side of the second connecting block close to the guide portion.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a position adjustment mechanism and an angle adjustment mechanism, not only can the staff only need to stand at a work station on one side of the sand box body to quickly complete the sand injection work, which not only reduces labor intensity but also significantly improves the sand injection efficiency; it also allows the staff to rotate the casting ladle body at a safe distance, so that the casting ladle body can rotate slowly and steadily, thereby ensuring that the molten iron flows into the sand box body at a uniform and slow speed, which not only ensures the integrity of the sand mold in the sand box body, but also provides safety protection for the staff.

[0016] By providing a first frame, a second frame and a first connecting rope in the position adjustment mechanism, the staff standing on the side close to the first frame can change the position of the sand outlet pipe opening by operating the handle so that it can be accurately aligned with different sand injection parts on the top of the sand box body. This operation method allows the staff to complete all the sand injection work of the sand box body without moving their bodies to change positions, and only needs to maintain a relaxed posture. It not only greatly reduces labor intensity and makes operation more convenient, but also effectively ensures the efficiency of the sand injection work.

[0017] By arranging a second connecting rope, a second connecting frame and a pulley in the angle adjustment mechanism, the ladle body can be rotated when the staff turns the handle with both hands, and the staff maintains a long distance from the ladle body, so that safety is effectively guaranteed. At the same time, by turning the handle to control the rotation of the handle, the ladle body can be kept in a slow and uniform tilt state, so that the internal molten iron can flow out smoothly and be injected into the designated position, thereby avoiding the sand mold in the ladle body from being damaged due to the excessive flow of molten iron.

[0018] By providing a second connecting block in the angle adjustment mechanism, the second connecting block can be installed on the handle more quickly by utilizing the guidance of the guide part, and during installation, the position of the second connecting block close to the second weakened portion is preferentially deformed, further making the installation of the second connecting block more convenient and quick. After the second connecting block is installed on the handle, the part of the second connecting block close to the second weakened portion deforms and rebounds, so that the opening of the second connecting block forms an extrusion limit on the handle, further ensuring the stability of the installation of the second connecting block.

[0019] In summary, this device can not only make the ductile iron casting work efficient and stable through the coordinated use of the position adjustment mechanism and the angle adjustment mechanism and the various components therein, but also reduce labor and ensure the safety of the workers.

[0029] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a ductile iron casting molding device, including an operating table 1, a sand box body 2 is provided on the operating table 1, a hanger 3 is provided on the top of the sand box body 2, a ladle body 4 is provided at the bottom of the hanger 3, a sand supply mechanism 5 is provided on the top of the sand box body 2, and a sand outlet pipe 6 is installed on one side of the sand supply mechanism 5. Optionally, the operating table 1 is stationary and relies on an external driving device to drive the sand box body 2 to move to the next workstation, and the driving mechanism is an existing mature technology; the optional sand box body 2 is composed of a positioning and closing mechanism, a fastening mechanism, a lifting and supporting mechanism, and an exhaust and sand cleaning mechanism, and the positioning and closing mechanism, the fastening mechanism, the lifting and supporting mechanism, and the exhaust and sand cleaning mechanism are composed of existing mature technologies. , so its working principle and specific structure are not described in detail here; optionally, a guide rail frame is installed on the top of the hanger 3, and a slider is provided on the guide rail frame, which is connected to the hanger 3, and the slider is manually pulled to make the hanger 3 move along the guide rail, wherein the guide rail frame and the slider are existing mature technologies, so its working principle and specific structure are not described in detail here; the pouring barrel body 4 includes a barrel body, a pouring nozzle, a barrel ear and a hanging shaft and a tilting and control mechanism, wherein the barrel body, the pouring nozzle, the barrel ear and the hanging shaft and the tilting and control mechanism are existing mature technologies, so its working principle and specific structure are not described in detail here; the sand supply mechanism 5 includes a sand bin, a sand conveying system, a sand quantity control system and an installation mechanism, wherein the sand The silo, sand conveying system, sand quantity control system and installation mechanism are existing mature technologies, so their working principles and specific structures are not described in detail here; therefore, the above-mentioned operating table 1, sand box body 2, hanger 3, pouring bucket body 4, sand supply mechanism 5 and sand outlet pipe 6 are all existing mature technologies, so their working principles and specific structures are not described in detail here; position adjustment mechanism, the position adjustment mechanism is used to adjust the position of the opening of the sand outlet pipe 6, and the position adjustment mechanism is connected to the sand supply mechanism 5; angle adjustment mechanism, the angle adjustment mechanism is used to adjust the inclination angle of the pouring bucket body 4, and the angle adjustment mechanism is connected to the position adjustment mechanism. When the sand in the sand supply mechanism 5 is injected into the sand box body 2, the staff It is necessary to hold the sand outlet pipe 6 and adjust its position so that the opening of the sand outlet pipe 6 is aligned with the sand injection position on the top of the sand box body 2. However, due to the large size of the metal model, the staff cannot complete the sand injection at a single position and need to repeatedly adjust their own position and posture. The operation process is cumbersome and seriously affects work efficiency. The application of the position adjustment mechanism in this device allows the staff to quickly complete the sand injection work by standing at a work station on one side of the sand box body 2, which not only reduces labor intensity but also significantly improves the sand injection efficiency. In addition, in the process of pouring molten iron from the ladle body 4 into the sand box body 2, it is necessary to stably control the iron injection speed. The previous method of manually rotating the ladle body 4 to tilt it to pour out the molten iron is difficult to accurately control the rotation speed.Moreover, if the staff is too close to the molten iron and the ladle body 4 tilts too quickly, not only will the sand mold inside the ladle body 4 be damaged, but there is also a risk of scalding. The present device cooperates with the angle adjustment mechanism and the position adjustment mechanism to enable the staff to rotate the ladle body 4 at a safe distance, thereby achieving a slow and stable rotation of the ladle body 4, thereby ensuring that the molten iron flows into the sand box body 2 at a uniform and slow speed, which not only ensures the integrity of the sand mold inside the sand box body 2, but also provides safety for the staff.

[0030] like Figures 2 to 4 and Figures 7 to 10 As shown, the position adjustment mechanism includes a first skeleton 7 installed at the bottom of the sand supply mechanism 5, the first skeleton 7 is fixedly connected to the second skeleton 8 on the side close to the sand outlet pipe 6, and the second skeleton 8 is fixedly connected to the first connecting block 9 at one end away from the first skeleton 7, and a first connecting frame 13 is installed at the bottom of the first skeleton 7, and a rotating block 14 is rotatably connected to the first connecting frame 13. Both sides of the rotating block 14 are fixedly connected to a handle 15, and a first connecting rope 12 is installed at the bottom of the second skeleton 8. The end of the first connecting rope 12 close to the second skeleton 8 is fixedly connected to the third connecting block 23. The sand outlet pipe 6 is a corrugated pipe, and the third connecting block 23 is fixed on the side of the second skeleton 8 close to the first connecting block 9. The end of the first connecting rope 12 away from the third connecting block 23 is wound and fixed on the rotating block 14. The second skeleton 8, the first connecting rope 12 and the first skeleton 7 form a structure close to a triangle. The staff stands on the side close to the first skeleton 7, holds the two handles 15 with both hands and rotates, which can drive the rotating block 14 to rotate on the first connecting frame 13, prompting the first connecting rope 12 to be more wound around the rotating block 14. During this process, the first connecting rope 12 will pull the second skeleton 8 to cause it to deform, thereby changing the position of the opening of the sand outlet pipe 6 so that it can be accurately aligned with the different sand injection parts on the top of the sand box body 2. With this operation method, the staff does not need to move their bodies to change positions, but only needs to maintain a relaxed posture to complete all the sand injection work of the sand box body 2. This not only greatly reduces the labor intensity and makes the operation more convenient, but also effectively ensures the efficiency of the sand injection work.

[0031] Furthermore, both sides of the second frame 8 are fixedly connected with the third frame 10, which enhances the stability of the second frame 8 and ensures that the second frame 8 can be restored to its initial state when the external force is removed. The second frame 8 and the third frame 10 are an integrated structure. The integrated structure has good stability and is convenient to produce, transport and use. A first weakened portion 11 is provided on the top of the second frame 8, which enhances the deformation ability of the second frame 8 so that the second frame 8 will first deform from the first weakened portion 11 when subjected to external force. The second frame 8 is made of plastic material, which has good deformation ability. The first connecting frame 13 is hook-shaped, and the first connecting frame 13 is away from the first One end of the skeleton 7 is fixedly connected to a limiting plate 19, so that the turning block 14 and the handle 15 can be stably installed on the first connecting frame 13 for use. The surface of the turning block 14 is provided with threads, which makes the turning block 14 more anti-slip. The outer wall of the handle 15 is provided with anti-slip grooves. The handle 15 is provided with a plurality of recesses and protrusions at equal intervals in a ring, so that the staff can hold the handle 15 stably with their hands, which is convenient for the staff to rotate the handle 15 and prevent side slipping during work. The second skeleton 8 and the third skeleton 10 are both arc-shaped structures convex to the top, so that the deformation tendency of the second skeleton 8 and the third skeleton 10 is better. The first skeleton 7 is cross-shaped with a simple structure, which is convenient for orderly installation of various components on the first skeleton 7 for use.

[0032] like Figures 3 to 8 As shown, the angle adjustment mechanism includes a second connecting frame 17 mounted on the first frame 7. A pulley 18 is rotatably connected to the second connecting frame 17. A second connecting rope 16 is provided at the bottom of the pulley 18. The end of the second connecting rope 16 near the ladle body 4 is fixedly connected to a second connecting block 20. A turning handle 24 is mounted on the side of the ladle body 4 near the second connecting block 20. The second connecting frame 17 is L-shaped, and the pulley 18 has a groove that matches the shape of the second connecting rope 16. The second connecting rope 16 is hung on the pulley 18 and bent to form an acute angle. The second connecting block 20 is mounted on the turning handle 24, and the end of the second connecting block 20 away from the turning handle 24 is wrapped and fixed around the turning block 14. When a worker rotates the handle 15 with both hands, the length of the second connecting rope 16 wrapped around the turning block 14 changes, thereby pulling the turning handle 24 and driving it to rotate, ultimately rotating the ladle body 4. During this process, the worker maintains a distance from the ladle body 4, effectively ensuring safety. At the same time, by turning the handle 15 to control the rotation of the handle 24, the ladle body 4 can be kept in a slow and uniform tilt state, so that the internal molten iron can flow out smoothly and be injected into the designated position, thereby avoiding the sand mold in the ladle body 4 from being damaged due to the excessive flow of molten iron.

[0033] Furthermore, the shape of the second connecting block 20 is compatible with the shape of the turning handle 24. The second connecting block 20 is made of stainless steel, so the second connecting block 20 can be stably installed on the turning handle 24. A guide portion 21 is provided on one side of the second connecting block 20, and a second weakened portion 22 is provided on the side of the second connecting block 20 close to the guide portion 21. By utilizing the guidance of the guide portion 21, the second connecting block 20 can be installed on the turning handle 24 more quickly, and during installation, the position of the second connecting block 20 close to the second weakened portion 22 is deformed first, further making the installation of the second connecting block 20 more convenient and quick. After the second connecting block 20 is installed on the turning handle 24, the part of the second connecting block 20 close to the second weakened portion 22 is deformed and rebounded, so that the opening of the second connecting block 20 forms an extrusion limit on the turning handle 24, further ensuring the stability of the installation of the second connecting block 20.

[0034] The working principle of the technical solution provided by the present invention is as follows: When injecting sand into the sand box body 2, a staff member first stands on the side near the first frame 7, holds the two handles 15 with both hands and rotates them, driving the rotating block 14 to rotate on the first connecting frame 13, causing the first connecting rope 12 to be more wrapped around the rotating block 14. During this process, the first connecting rope 12 will pull the second frame 8 to cause it to deform, thereby changing the position of the opening of the sand outlet pipe 6 so that it can be accurately aligned with different sand injection locations on the top of the sand box body 2. After one round of sand injection is completed, the first connecting rope 12 wrapped around the rotating block 14 is released, and the second frame 8 and the third frame 10 will deform and rebound, driving the sand outlet pipe 6 to return to its original position so that the next sand injection operation into the sand box body 2 can be carried out. The operating table 1 is an operating platform, which can be stationary and rely on an external driving device to drive the pouring ladle body 4 to move to the next work station; or it can be a conveyor belt with its own driving mechanism, etc., which drives the sand box body 2 thereon to move. The operating table 1 is not limited here, and the driving mechanism is an existing mature technology; in conjunction with the movement of the sand box body 2, the staff changes the opening position of the sand outlet pipe 6 by turning the handle 15. There is no need to move the body to change position. All sand filling work of the sand box body 2 can be completed by maintaining a relaxed posture, which greatly reduces the labor intensity, makes the operation more convenient, and effectively guarantees the sand filling efficiency.

[0035] After the sand injection is completed, the sand box body 2 moves to the next workstation to trim and reinforce the formed sand mold, and then is sent to the next workstation to adjust the position of the pouring bucket body 4 using the existing control mechanism. The control mechanism is an existing mature technology, which aligns the sand box body 2 with the pouring bucket body 4. The staff near the first skeleton 7 uses the guidance of the guide part 21 to install the second connecting block 20 on the handle 24 more quickly. During installation, the position of the second connecting block 20 near the second weakened part 22 is deformed first, which further facilitates the installation of the second connecting block 20. After installation, the portion of the second connecting block 20 near the second weakened portion 22 deforms and rebounds, with its opening forming a squeeze limiter on the turning handle 24. The initial installation position of the second connecting block 20 is at the very bottom of the turning handle 24, facilitating the second connecting rope 16 to pull the turning handle 24 for better rotation. The worker rotates the handle 15 with both hands, changing the length of the second connecting rope 16 wrapped around the turning block 14. This in turn pulls the turning handle 24 and drives it to rotate, ultimately achieving rotation of the ladle body 4. During this process, the worker maintains a distance from the ladle body 4, effectively ensuring safety. Simultaneously, controlling the rotation of the turning handle 24 by turning the handle 15 allows the ladle body 4 to maintain a slow and even tilt, allowing the molten iron inside to flow smoothly out and into the designated location, preventing damage to the sand mold within the ladle body 4 due to excessive molten iron flow. After pouring is complete, the turning block 14 releases the limiter on the second connecting rope 16, and the ladle body 4 is reset for the next pour. The flask body 2 is then moved to the next station for subsequent operations. The device can assist manual operation, reduce manual labor intensity, and ensure the safety of workers.

Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0037] The above is only a preferred embodiment of the present invention.

These improvements and modifications should also be regarded as within the scope of protection of the present invention.
