Description

Technical Field

[0001] This utility model relates to the field of automation technology in smelting and casting steel, specifically to an automatic tilting device for a base plate used in casting. Background Technology

[0002] In the die-casting steel smelting process, the ingot mold base plate, which supports the mold, is a crucial part of the die-casting production line. After the cast ingot mold is removed, the base plate will retain remnants such as flow bricks, runners from solidified molten steel, and sand mold material supporting the flow bricks. These remnants must be removed before the base plate can be used for further steel casting. Because the base plate reaches extremely high temperatures after demolding, there is a risk of burns. Therefore, a set of equipment that meets the following conditions needs to be designed:

[0003] 1. It can achieve automated control, avoiding waste of manpower;

[0004] 2. The equipment is safe and reliable to use, reducing excessive human intervention and avoiding excessive exposure of personnel to high temperatures. Utility Model Content

[0005] The purpose of this invention is to provide an automatic tilting device for the base plate of a die casting machine, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic tilting device for base plates used in die casting, comprising a frame, a first tilting mechanism, a second tilting mechanism, a collecting device, and a control system. The frame is fixedly installed on the ground. The first tilting mechanism includes a receiving frame, a first driving assembly, and a first rotating shaft assembly. The receiving frame is rotatably mounted on the frame via the first rotating shaft assembly. The first driving assembly is connected to the receiving frame via the first rotating shaft assembly. The first driving assembly can drive the receiving frame, which is in its original position, to move to a first position and a second position. When the receiving frame is in its original position, it receives the base plate containing the residue to be cleaned. The second tilting mechanism includes a tilting frame, a second driving assembly, and a second rotating shaft assembly. The tilting frame is rotatably mounted on the frame via a second rotating shaft assembly. The second drive assembly is connected to the tilting frame via the second rotating shaft assembly. The second drive assembly can drive the tilting frame to move to the first station, the second station, and the third station. The tilting frame at the first station cooperates with the receiving frame at the first station to form a receiving space for clamping the base plate, and moves together to the second station. The collecting device is used to collect the debris that falls off the base plate when the tilting frame is at the third station. The control system is communicatively connected to the first drive assembly and the second drive assembly. When the receiving frame and the tilting frame are at the first station, the base plate is pressed against the receiving frame by gravity. When the receiving frame and the tilting frame are at the second station, the base plate is pressed against the tilting frame by gravity.

[0007] Based on the above technical features, the receiving frame in this utility model is used to receive the base plate containing the residue to be cleaned. When the base plate enters the receiving frame, and the control system detects that the base plate is in place, the control system controls the receiving frame to automatically flip via the first drive component. When the receiving frame flips to the designated position, the tilting frame rises and receives the base plate that has been flipped over by the receiving frame. The tilting frame then flips the base plate to knock off the residue, sending it into the collection device. Finally, the control system controls the first and second flipping mechanisms to flip the base plate back to its original position, facilitating the transfer of the base plate. This utility model requires no human intervention during the base plate cleaning process, achieving fully automated, unmanned operation and avoiding safety accidents such as burns and heatstroke that could occur from direct contact between the cleaning worker and the base plate.

[0008] In a preferred embodiment of this technical solution, the first rotating shaft assembly includes a first pin rotatably mounted on the frame, and the receiving frame is fixedly connected to the first pin and can rotate around the first pin. More preferably, the second rotating shaft assembly includes a second pin rotatably mounted on the frame, and the tilting frame is fixedly connected to the second pin and can rotate around the second pin; the first and second pins are arranged along a first direction and both extend along a second direction.

[0009] Based on the above technical features, the pin shaft, as a power transmission component, is not only easy to disassemble, but also has a simple structure, stable power transmission, and strong durability. At the same time, by using two parallel double pin shaft structures as power transmission components for the receiving frame and the tilting frame respectively, the receiving frame and the tilting frame can rotate synchronously, so that the tilting frame can smoothly support the base plate that the receiving frame flips over.

[0010] In this preferred embodiment, the first drive assembly includes a lifting cylinder and a first displacement sensor for detecting the extension length of the lifting cylinder. One end of the lifting cylinder is hinged to the frame, and the other end is fixed to a first pin. The second drive assembly includes a tilting cylinder and a second displacement sensor for detecting the extension length of the tilting cylinder. One end of the tilting cylinder is hinged to the frame, and the other end is fixed to a second pin. Both the first and second displacement sensors are communicatively connected to the control system.

[0011] Based on the above technical features, displacement sensors are respectively installed on the lifting cylinder and the tilting cylinder to effectively detect the length of the cylinder extension and transmit the detection signal to the control system, which then converts it into the flipping angle of the receiving frame and the tilting frame.

[0012] In this preferred embodiment, the receiving frame forms a receiving surface on one side of the receiving and cleaning base plate. A limiting block is provided on the receiving surface, dividing the receiving surface into a receiving part and an extending part from the position of the limiting block. During the process of the receiving frame rotating from the original station to the second station, the base plate is located in the receiving part, and one end of the base plate abuts against the limiting block to form a limiting position. When the receiving frame is in the second station, and during the process of the tilting frame rotating from the second station to the third station, the end of the extending part away from the limiting block is flush with the receiving surface of the tilting frame used to receive the base plate.

[0013] Based on the above technical features, the receiving frame is equipped with a limiting block to support the base plate, so as to prevent the base plate from detaching from the receiving frame during the rotation of the receiving frame. At the same time, the receiving surface of the receiving frame used to support the base plate is divided into a receiving part and an extension part. During the process of the tilting frame rotating from the second station to the third station away from the receiving frame, the base plate can gradually slide onto the tilting frame through the extension part, so as to achieve the continuity of the base plate transfer.

[0014] In a preferred embodiment of this technical solution, the tilting frame includes two longitudinal bars and several crossbeams disposed on the longitudinal bars. The longitudinal bars are arranged along a second direction and extend along a first direction. The crossbeams are mounted on the longitudinal bars. The several crossbeams are arranged along the first direction and extend along the second direction. The longitudinal bars and crossbeams can cooperate to form a load-bearing surface of the tilting frame. At the same time, the load-bearing surface forms a hollow space for the bottom plate residue to fall into the collection device.

[0015] Based on the above technical features, the longitudinal bars provide the main longitudinal load-bearing path, and several crossbeams are connected laterally to form a grid structure, which effectively supports the base plate and distributes the load. At the same time, the hollow space formed by the cooperation between the longitudinal bars and crossbeams can also meet the space requirements for the fall of objects left on the base plate, effectively improving the overall performance of the structure.

[0016] In this preferred embodiment, the collection device includes a vibrating screen, a slag hopper, and a vibrating motor. The vibrating screen is mounted on a frame. When the tilting frame is in the third position, the vibrating screen is located at the bottom of the hollow space in the tilting frame, used to receive residue falling from the bottom plate. The slag hopper is located at the discharge port of the vibrating screen. The vibrating motor is located at the bottom of the vibrating screen, used to vibrate the residue collected in the vibrating screen into the slag hopper.

[0017] Based on the above technical features, the vibrating screen is located below the tilting frame and is used to collect the residue that falls off the bottom plate after the tilting frame flips over. The vibrating motor is installed at the bottom of the vibrating screen to make the vibrating screen vibrate and shake the residue inside the vibrating screen into the slag hopper.

[0018] Preferably, this technical solution further includes a buffer device. When the tilting frame rotates to the third position, the tilting frame impacts the buffer device, which absorbs the impact and vibration when the tilting frame rotates to the third position. More preferably, the buffer device includes a frame and a damper. Two frames are respectively disposed on the left and right sides of the vibrating screen. The damper is fixedly installed on the top of the frame. When the tilting frame rotates to the third position, the longitudinal rods in the tilting frame impact the damper, which absorbs the impact and vibration when the tilting frame rotates to the third position.

[0019] Based on the above technical features, when the tilting frame rotates to the third position, the tilting frame will perform a slag-knocking action to knock off the residue on the bottom plate and scatter it into the vibrating screen. Therefore, in order to effectively protect the tilting frame, buffers are set on the left and right sides of the vibrating screen to absorb the impact and vibration generated by the tilting frame turning to the third position to complete the slag-knocking action.

[0020] In this preferred embodiment, a buffer spring is also included, and the vibrating screen is connected to the frame via the buffer spring.

[0021] Based on the above technical features, a buffer spring is installed between the vibrating screen and the frame to absorb and disperse the impact force generated when the vibrating screen vibrates through elastic deformation, so as to achieve shock reduction, buffering and mechanical protection.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be further discussed and described in the description of the subsequent figures.

[0037] like Figures 1 to 10 As shown, this utility model provides a technical solution: an automatic tilting device for a base plate used in die casting, wherein the automatic tilting device includes a frame 1, a first tilting mechanism 2, a second tilting mechanism 3, a collecting device 4, and a control system.

[0038] The frame 1 is fixedly installed on the ground. For example, the frame 1 can be installed on the ground by a number of anchor bolts.

[0039] The first flipping mechanism 2 includes a receiving frame 21, a first driving component, and a first rotating shaft component. The receiving frame 21 is rotatably mounted on the frame 1 via the first rotating shaft component. The first driving component is connected to the receiving frame 21 via the first rotating shaft component. The first driving component can drive the receiving frame 21, which is in its original position, to move to the first position and the second position. When the receiving frame 21 is in its original position, the receiving frame 21 is used to receive the bottom plate 7 of the residue to be cleaned.

[0040] The second tilting mechanism 3 includes a tilting frame 31, a second drive assembly, and a second rotating shaft assembly. The tilting frame 31 is rotatably mounted on the frame 1 via the second rotating shaft assembly. The second drive assembly is connected to the tilting frame 31 via the second rotating shaft assembly. The second drive assembly can drive the tilting frame 31 to move to the first station, the second station, and the third station. The tilting frame 31 at the first station cooperates with the receiving frame 21 at the first station to form an accommodating space for clamping the base plate 7, and together they move to the second station.

[0041] When the receiving frame 21 and the tilting frame 31 are in the first position, the base plate 7 is in contact with the receiving frame 21 by gravity. When the receiving frame 21 and the tilting frame 31 are in the second position, the base plate 7 is in contact with the tilting frame 31 by gravity. The "gravity contact" mentioned above refers to the state in which the base plate 7 forms a static equilibrium with the receiving frame 21 or the tilting frame 31 through its own weight and other forces.

[0042] like Figure 1 and Figure 6As shown, the first rotating shaft assembly includes a first pin 23 rotatably mounted on the frame 1, and a receiving frame 21 fixedly connected to the first pin 23 and rotatable around the first pin 23. The second rotating shaft assembly includes a second pin 33 rotatably mounted on the frame 1, and a tilting frame 31 fixedly connected to the second pin 33 and rotatable around the second pin 33. The first pin 23 and the second pin 33 are arranged along a first direction and both extend along a second direction. By using two parallel double-pin structures as power transmission components for the receiving frame 21 and the tilting frame 31 respectively, the receiving frame 31 and the tilting frame 31 can rotate synchronously, so that the tilting frame 31 can smoothly support the base plate 7 that has been flipped over by the receiving frame 21.

[0043] like Figure 3 and Figure 6 As shown, the receiving frame 21 has one side of the receiving and cleaning base plate 7 as a receiving surface. A limiting block 24 is provided on the receiving surface, dividing the receiving surface into a receiving part 211 and an extension part 212 from the position of the limiting block 24. When the receiving frame 21 rotates from the original station to the second station, the base plate 7 is located in the receiving part 211, and one end of the base plate 7 abuts against the limiting block 24 to form a limit, so as to prevent the base plate 7 from detaching from the receiving frame 21 during the rotation of the receiving frame 21. When the receiving frame 21 is in the second station and the tilting frame 31 rotates from the second station to the third station, the end of the extension 212 away from the limiting block 24 is flush with the receiving surface of the tilting frame 31 used to receive the base plate 7. As the tilting frame 31 rotates from the second station to the third station and the receiving surface of the tilting frame 31 moves away from the receiving frame 21, the base plate 7 can gradually slide onto the tilting frame 31 through the extension 212, thus achieving the continuity of the transfer of the base plate 7.

[0044] like Figure 1 , Figure 2 and Figure 6 As shown, the tilting frame 31 includes two longitudinal bars 311 and several crossbeams 312 arranged on the longitudinal bars 311. The longitudinal bars 311 are arranged along a second direction and extend along a first direction. The crossbeams 312 are installed on the longitudinal bars 311, and the several crossbeams 312 are arranged along the first direction and extend along the second direction. The longitudinal bars 311 and the crossbeams 312 can cooperate to form a bearing surface of the tilting frame 31. At the same time, the bearing surface forms a hollow space for the residue left on the bottom plate 7 to fall into the collection device 4. The longitudinal bars 311 provide the main longitudinal bearing path, and the several crossbeams 312 are connected laterally to form a grid structure, which effectively supports the bottom plate 7 and distributes the load. At the same time, the hollow space formed by the cooperation between the longitudinal bars 311 and the crossbeams 312 can also be adapted to the space requirements for the drop of residue left on the bottom plate 7, effectively improving the overall performance of the structure.

[0045] The control system is communicatively connected to the first drive component and the second drive component.

[0046] like Figures 1 to 7 As shown, the first drive assembly includes a lifting cylinder 22 and a first displacement sensor for detecting the extension length of the lifting cylinder 22. One end of the lifting cylinder 22 is hinged to the frame 1, and the other end is fixed to the first pin 23. The second drive assembly includes a tilting cylinder 32 and a second displacement sensor for detecting the extension length of the tilting cylinder 32. One end of the tilting cylinder 32 is hinged to the frame 1, and the other end is fixed to the second pin 33. Both the first and second displacement sensors are communicatively connected to the control system. The control system receives the extension length detection signal of the lifting cylinder 22 detected by the first displacement sensor and the extension length detection signal of the tilting cylinder 32 detected by the second displacement sensor, and converts it into the flipping angle of the receiving frame 21 and the tilting frame 31. By controlling the lifting cylinder 22 or the tilting cylinder 32, the control system can flip the receiving frame 21 to a specified position: the original position, the first position, or the second position, and flip the tilting frame 31 to a specified position: the first position, the second position, or the third position.

[0047] The collection device 4 is used to collect the steel bricks, molten steel bars, and sand mold materials that support the steel bricks that fall from the base plate 7 when the tilting frame 31 is in the third position.

[0048] like Figures 1 to 9 As shown, the collection device 4 includes a vibrating screen 41, a slag hopper 42, a vibrating motor 43, and a screen plate 44. The vibrating screen 41 is installed on the frame 1. When the tilting frame 31 is in the third position, the vibrating screen 41 is located at the bottom of the hollow space in the tilting frame 31 to receive the residue falling from the bottom plate 7. The slag hopper 42 is located at the discharge port of the vibrating screen 41. The vibrating motor 43 is located at the bottom of the vibrating screen 41 to vibrate the residue collected in the vibrating screen 41 into the slag hopper 42. The vibrating screen 41 is designed with an inherent tilt angle during installation. Therefore, with vibration, the residue in the vibrating screen 41 will be more easily vibrated into the slag hopper 42, which can thoroughly clean the residue on the bottom plate 7. The slag hopper 42 is divided into a first slag hopper 421 and a second slag hopper 422. A screen plate 44 is provided on the screen surface of the vibrating screen 41. As the vibrating screen 41 vibrates, the sand material in the residue will flow through the screen plate 44 into the first slag hopper 421 for secondary recycling. Meanwhile, the fallen steel bricks and the molten steel solidification bars in the residue will flow into the second slag hopper 422 for collection.

[0049] like Figure 4 , Figure 5 , Figures 7 to 9As shown, the automatic tilting device also includes a buffer spring 6. The vibrating screen 41 is connected to the frame 1 through the buffer spring 6. The buffer spring 6 is used to absorb and disperse the impact force generated when the vibrating screen 41 vibrates through elastic deformation, so as to achieve shock reduction, buffering and mechanical protection.

[0050] like Figures 1 to 7 As shown, the automatic tilting device also includes a buffer device 5. The tilting frame 31 cleans up the residue on the base plate 7. When the tilting frame 31 rotates to the third position, it will perform a knocking action and hit the buffer device 5. The buffer device 5 is used to absorb the impact and vibration when the tilting frame 31 rotates to the third position.

[0051] The buffer device 5 includes a frame 51 and a buffer 52. The frame 51 includes two frames, which are respectively set on the left and right sides of the vibrating screen 41. The buffer 52 is fixedly installed on the top of the frame 51. When the tilting frame 31 rotates to the third position, the longitudinal rod 311 in the tilting frame 31 impacts the buffer 52. The buffer 52 is used to absorb the impact and vibration when the tilting frame 31 rotates to the third position.

[0052] like Figure 10 The diagram shows the structure of the buffer 52, which is fixed to the top of the frame 51 by a connecting plate and bolts.

[0053] In a specific embodiment of this utility model, when the receiving frame 21 is in its original position, the angle between the receiving frame 21 and the horizontal plane is 0 degrees. When the receiving frame 21 is flipped to the first position, the angle between the receiving frame 21 and the horizontal plane is 85 degrees. When the receiving frame 21 is flipped to the second position, the angle between the receiving frame 21 and the horizontal plane is 95 degrees. When the tilting frame 31 is in the first position, the angle between the tilting frame 31 and the horizontal plane is 85 degrees. When the tilting frame 31 is flipped to the second position, the angle between the tilting frame 31 and the horizontal plane is 95 degrees. When the tilting frame 31 is flipped to the third position, the angle between the tilting frame 31 and the horizontal plane is 180 degrees.

[0054] In this invention, the control system is the key to enabling the automatic tilting device to operate automatically. The base plate 7 enters the receiving frame 21. After the limit sensor detects that the base plate is in place, the receiving frame 21 automatically tilts. Controlled by the first displacement sensor, after tilting to the designated position, the tilting frame 31 rises to receive the base plate 7. The tilting frame 31 then tilts the base plate 7 180 degrees and performs a slag-knocking action, knocking the residue on the base plate 7 into the vibrating screen 41. Subsequently, the vibrating motor 43 automatically starts, vibrating the residue in the vibrating screen 41 into the slag hopper 42. Simultaneously, through the control system, the base plate 7 is tilted back to 0 degrees by the tilting frame 31 and the receiving frame 21, facilitating the transfer of the base plate 7. The entire process can quickly and effectively remove the residue on the base plate 7 after the molded steel is demolded. It only takes five minutes to flip a base plate 7, ensuring the rhythm of the molded production line and greatly improving the efficiency of the molded production line. At the same time, it can also realize fully automatic flipping of the base plate 7 for slag removal, avoiding the safety accidents of burns and heatstroke caused by direct contact between the slag remover and the base plate 7 during manual slag removal.

[0055] Specifically, the automatic tilting device removes the residue from the bottom plate 7 as follows:

[0056] Step 1: When the base plate 7 is placed on the receiving frame 21, the limit detection on the receiving frame 21 indicates that the base plate 7 is in place. Then, the tilting cylinder 32 in the second tilting mechanism 3 automatically extends, causing the tilting frame 31 to start to tilt until it automatically stops when it tilts to 85 degrees (first station).

[0057] Step 2: The lifting cylinder 22 in the first flipping mechanism 2 extends automatically, causing the receiving frame 21 to start flipping with the base plate 7 until the receiving frame 21 flips to 85 degrees and then stops automatically. At this time, the receiving frame 21 and the tilting frame 31 clamp the base plate 7 in the middle.

[0058] Step 3: The receiving frame 21 and the tilting frame 31 rotate to 95 degrees simultaneously (second station), at which point the base plate 7 is already close to the tilting frame 3.

[0059] Step 4: The tilting frame 31, along with the base plate 7, begins to rotate to 180 degrees (third station) and then automatically stops.

[0060] Step 5: By controlling the tilting cylinder 32 to perform a slag-knocking action on the tilting frame 31, the residue attached to the bottom plate 7 is knocked off and falls into the slag hopper 42.

[0061] Step 6: The tilting frame 31, along with the cleaned base plate 7, is rotated to 95 degrees, at which point the receiving frame 21 is also at 95 degrees.

[0062] Step 7: The receiving frame 21 and the tilting frame 31, along with the base plate 7, rotate simultaneously to 85 degrees.

[0063] Step 8: The receiving frame 21, along with the base plate 7, is rotated to 0 degrees (original work position).

[0064] Step 9: The tilting frame 31 is rotated to 180 degrees, and at the same time the vibrating motor 43 starts to vibrate, gradually shaking the residue in the vibrating screen 41 into the slag hopper 42, thus completing the entire process.

[0065] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
