Description

Technical Field

[0001] The present invention relates to the technical field of metal piston casting, and particularly relates to a continuous casting device for aluminum alloy pistons. Background Art

[0002] ‌The casting of aluminum alloy metal pistons‌ refers to the process of making pistons from aluminum alloy materials through a casting process. Aluminum alloy pistons are widely used in automobile engines and have the advantages of light weight, high strength, corrosion resistance, etc., which can significantly improve the performance and fuel economy of the engine. Die casting is to inject molten aluminum alloy into a metal mold and make it solidify and form by relying on gravity or pressure. The advantages of die casting include high production efficiency, low cost, high dimensional accuracy, smooth surface, etc.

[0003] In the production process of aluminum alloy pistons, after the aluminum alloy liquid is poured into the mold, the dross on the surface of the aluminum alloy liquid needs to be removed. Despite the continuous development of automation technology, manual cleaning is still an important supplement in certain scenarios. Manual cleaning usually requires the use of special tools such as slag raking shovels to operate in a high-temperature environment. The temperature of the aluminum liquid is generally about seven hundred degrees Celsius. When workers skim the slag at this temperature, once there is moisture in the mold, the high-temperature aluminum liquid may explode during pouring, endangering the lives of the slag skimming workers. Moreover, the working efficiency of manual cleaning is relatively low. Therefore, the present application provides a continuous casting device for aluminum alloy pistons to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a continuous casting device for aluminum alloy pistons. By setting up a metal casting slag pressing mechanism and a metal casting slag collecting mechanism, not only can the slag generated by the molten metal in the furnace body be quickly taken out, but also the contact area and duration between the aluminum alloy and air during the metal melting process can be effectively reduced, thereby reducing the generation of metal slag. Through the above settings, the problem of unsafe manual slag cleaning in the existing aluminum alloy piston manufacturing process can be solved.

[0008] Optionally, the cross-section of the first pressing plate is L-shaped. A limiting groove is formed at the bottom of the first pressing plate. The second pressing plate and the connecting plate are integrally formed. A fixing frame is installed on one side of the furnace body. The top of the fixing frame is rotatably connected to a first rotating shaft.

[0009] Optionally, a pressing piece adapted to the shape of the limiting groove is provided at the bottom of the furnace body. The top of the pressing piece is fixedly connected to a first connecting strip. The top of the first connecting strip is fixedly connected to a second connecting strip.

[0010] Optionally, a first weakening part is formed on the connecting plate. A guiding part is provided at the top of the connecting plate. An extrusion part is provided on one side of the connecting plate close to the guiding part.

[0011] Optionally, second weakening parts are annularly and equidistantly formed on the second pressing plate. A third weakening part is formed at the top of the second pressing plate.

[0012] Optionally, the metal casting slag holding mechanism includes a collecting box installed on one side of the main body of the casting device. A collecting cavity is formed in the collecting box. A baffle body is installed in the collecting cavity. Adsorbing blocks are installed on the inner walls of both sides of the collecting box. A vibrating machine body is installed on one side of the collecting box.

[0013] Optionally, second rotating shafts are installed on both sides of the top of the collecting box. One side of the second rotating shaft away from the collecting box is rotatably connected to a cover plate. A connecting piece is fixedly connected to the top of the cover plate.

[0014] Optionally, concave parts are equidistantly formed on the cover plate. The side of the cover plate away from the collecting box is serrated. A handle is installed on the outer wall of one side of the top of the cover plate.

[0015] Optionally, a fourth weakening part is formed on the connecting piece. Lightening grooves are equidistantly formed on the connecting piece.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting up a metal casting slag pressing mechanism and a metal casting slag holding mechanism, not only can the slag generated by the molten metal in the furnace body be quickly removed, but also the contact area and duration between the molten aluminum alloy and air during the metal melting process can be effectively reduced, thereby reducing the generation of metal slag, further facilitating the collection and treatment of metal slag. Moreover, the metal casting slag holding mechanism can quickly collect the removed metal slag and can simply classify the metal slag while collecting it, thus facilitating the subsequent recycling and treatment of the residue. Additionally, the metal casting slag holding mechanism can clean the components with metal oxide films generated on the inner surface of the device, so that each structure in the device can maintain a good working state. This device saves labor costs, makes the entire manufacturing process of the aluminum alloy piston safer, and the coordinated use of the structures effectively increases the working efficiency of continuous casting.

[0018] By providing a first pressing plate, a second pressing plate, a connecting plate, and a thin film in the metal casting slag pressing mechanism, not only can the contact area and contact duration between the molten metal during the entire process of scooping or standing still of the molten metal be effectively reduced by the coordinated use of the above structures, thereby reducing the amount of metal slag generated by the contact between the aluminum alloy and air, but also the generated metal slag can be extruded during the process of the pouring cup body scooping the molten aluminum alloy metal, so as to reduce the space occupied by the metal slag in the furnace body and facilitate fishing out the metal slag from the furnace body.

[0019] By providing a fixed rod in the metal casting slag pressing mechanism, and since one side of the connecting plate is fixed on the fixed rod, and the fixed rod does not deform during the use of the device, the connecting plate deforms to drive the second pressing plate to deform together, causing the second pressing plate to deform and move in the direction of the first pressing plate. The thin film on the top of the first pressing plate and the second pressing plate is squeezed and deformed accordingly. During the deformation of the connecting plate and the second pressing plate, the cavity space formed by the second pressing plate and the first pressing plate becomes smaller, and the metal slag generated inside is extruded, so that the connecting plate cooperates with other structures in the device to achieve the effect of pressing slag. Moreover, the fixed rod can be clamped by a mechanical clamping mechanism, so that the mechanical clamping mechanism takes out the connecting plate and the second pressing plate and the first pressing plate below it from the furnace body together, and then pours the collected metal slag into a collection box for collection, thus achieving the effect of quickly cleaning the metal slag.

[0020] By providing a baffle body and an adsorption block in the metal casting slag holding mechanism, not only can the magnetizable metal be adsorbed by the adsorption block when the metal slag passes near the adsorption block, but also after the adsorption block adsorbs a certain amount of metal slag, the vibration machine body causes the adsorption block to shake off the excess metal slag on it and collect it in a cavity formed by a baffle body and a collection box, and the other unadsorbed metal is collected in a cavity formed by two baffle bodies and a collection box.

[0021] By providing a cover plate and connecting pieces inside the metal casting slag holding mechanism, not only can the connecting pieces be used to make the cover plate naturally unfold and present an inclined shape without external force, so that when the first pressing plate and the second pressing plate are taken out of the melting furnace body, the cover plate naturally unfolds, and when the first pressing plate and the second pressing plate are put into the melting furnace body again, the first connecting bar and the second connecting bar pull the cover plate to close the cover plate, facilitating the pouring of metal slag into the collection box for collection. At the same time, when metal slag does not need to be collected, the cover plate is used to close the top of the collection box, and when the metal slag is poured into the collection box, the metal slag first falls on the inclined cover plate, and at the same time, the vibration machine body is started to vibrate the collection box and the cover plate thereon, so that the metal slag falls into the collection cavity more evenly and slowly, thus facilitating the collection of metal slag.

[0022] This device can not only reduce labor consumption and enhance work safety through the coordinated use of the metal casting slag pressing mechanism, the metal casting slag holding mechanism and each component therein, but also increase the working efficiency of continuous casting of aluminum alloy pistons to a certain extent. Moreover, the structure of this device is simple, convenient and fast to use, and the production cost of the device is low, with good practicability, facilitating popularization and use.

Detailed implementation manners

[0037] The following will describe in detail a continuous casting device for aluminum alloy pistons provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments, and are not intended to specifically limit the present invention.

[0038] As Figures 1 to 4As shown in the figure, an embodiment of the present invention provides a continuous casting device for aluminum alloy pistons, including a main body 1 of the casting device, a main body 2 of a robotic arm is installed on one side of the main body 1 of the casting device, a supporting arm 3 of the robotic arm is installed on one side of the main body 2 of the robotic arm, a pouring cup body 4 is installed on one side of the supporting arm 3 of the robotic arm, and a melting furnace body 5 is installed on one side of the main body 2 of the robotic arm; a metal casting slag pressing mechanism, which is used to squeeze the metal slag in the melting furnace body 5 together, and the metal casting slag pressing mechanism is connected to the melting furnace body 5; a metal casting slag collecting mechanism, which is used to collect and classify the metal slag, and the metal casting slag collecting mechanism is connected to the main body 1 of the casting device. The main body 1 of the casting device, the main body 2 of the robotic arm, the supporting arm 3 of the robotic arm, the pouring cup body 4 and the melting furnace body 5 are existing mature technologies, and their working principles and specific structural compositions will not be elaborated here. During the continuous casting of aluminum alloy pistons, the slag generated by the molten metal in the melting furnace body 5 can be quickly removed through the metal casting slag pressing mechanism, and the contact area and duration between the aluminum alloy and air during the metal melting process can also be effectively reduced, thereby reducing the generation of metal slag, further facilitating the collection and treatment of metal slag. Moreover, the metal casting slag collecting mechanism can quickly collect the removed metal slag and can simply classify the metal slag while collecting it, thus facilitating the subsequent recycling of the residue. In addition, the metal casting slag collecting mechanism can also clean the components with metal oxide films generated on the inner surface of the device, so that each structure in the device can maintain a good working state. The specific structures and working principles of the above-mentioned metal casting slag pressing mechanism and metal casting slag collecting mechanism will be described in detail below. And the structure of this device is simple, which saves labor costs, makes the entire manufacturing process of aluminum alloy pistons safer, and the coordinated use of the structures effectively increases the working efficiency of continuous casting.

[0039] As Figures 4 to 9As shown in the figure, the metal casting slag pressing mechanism includes a first pressing plate 6 installed on the furnace body 5. One side of the first pressing plate 6 is fixedly connected to a second pressing plate 7. The top of the second pressing plate 7 is fixedly connected to a connecting plate 8. One side of the connecting plate 8 is fixedly connected to a fixing rod 9. An overflow port 20 is provided on the top side wall of the second pressing plate 7. A thin film 16 is installed on the tops of the first pressing plate 6 and the second pressing plate 7. The connection between the thin film 16 and the first pressing plate 6 and the second pressing plate 7 is not limited to clamping or plugging. The first pressing plate 6, the second pressing plate 7 and the thin film 16 can be connected or separated through a connection structure. The specific connection structure is an existing mature technology and will not be elaborated here. The first pressing plate 6, the second pressing plate 7, the connecting plate 8, the fixing rod 9 and the overflow port 20 are all made of three-dimensional graphene material or carbon nanotube reinforced composite material, which has good high temperature resistance and the material itself has good elastic deformation ability. The specific material composition of the above components is not limited to carbon nanotube reinforced composite material, three-dimensional graphene material and superalloy composite material, etc., as long as its high temperature resistance number is greater than the temperature in the furnace body 5 and it has good deformation ability. The side of the fixing rod 9 away from the connecting plate 8 is fixedly connected to the top of the first pressing plate 6. During the continuous casting of aluminum alloy metal, the manipulator main body 2 is started to control the manipulator arm 3. By using the guidance of the connecting plate 8, the manipulator arm 3 and the pouring cup body 4 are moved closer to the furnace body 5. The side wall of the manipulator arm 3 is in direct contact with the connecting plate 8. The pouring cup body 4 does not have contact friction with the connecting plate 8 and other components in the metal casting slag pressing mechanism during the whole process of taking the molten metal in the furnace body 5. During the process of the pouring cup body 4 moving along the guidance of the connecting plate 8 towards the furnace body 5, since one side of the connecting plate 8 is fixed on the fixing rod 9 and the fixing rod 9 does not deform during the use of the device, the connecting plate 8 deforms and pulls the second pressing plate 7 to deform together, causing the second pressing plate 7 to deform and move towards the first pressing plate 6. The thin film 16 on the tops of the first pressing plate 6 and the second pressing plate 7 is squeezed and deformed accordingly. The two sides of the second pressing plate 7 are connected to the first pressing plate 6. The bottom of the second pressing plate 7 contacts but is not connected to the first pressing plate 6. The bottom of the first pressing plate 6 is adapted to the shape of the bottom of the furnace body 5. During the deformation of the connecting plate 8 and the second pressing plate 7, the cavity space formed by the second pressing plate 7 and the first pressing plate 6 becomes smaller, and the metal slag inside is squeezed.The bottom of the first pressing plate 6 is equidistantly provided with liquid outlets. When the first pressing plate 6 and the second pressing plate 7 are in contact with the inner wall of the melting furnace body 5, the liquid levels of the molten metal inside the two are lower than the height of the overflow port 20. When the pouring cup body 4 presses the connecting plate 8 and the second pressing plate 7 and moves towards the melting furnace body 5 until it is close to the overflow port 20, the first pressing plate 6 and the second pressing plate 7 squeeze the molten liquid inside them, causing the liquid level inside to rise close to the overflow port 20. Then, control the robotic arm main body 2 to adjust the angle and position of the pouring cup body 4 to align with the overflow port 20. Subsequently, control the robotic arm main body 2 again to further squeeze and deform the second pressing plate 7 by the pouring cup body 4 towards the first pressing plate 6, making the cavity space formed between the first pressing plate 6 and the second pressing plate 7 further smaller, so that the molten metal inside flows out from the overflow port 20 and is caught by the pouring cup body 4. Continuously squeeze the second pressing plate 7 until the pouring cup body 4 contains a sufficient amount of molten metal, then stop squeezing the second pressing plate 7. Then, control the robotic arm main body 2 to move the pouring cup body 4 away from the second pressing plate 7 and move it away from the melting furnace body 5 to take it out. The second pressing plate 7 and the connecting plate 8 that are released from the external force rebound to the initial state as shown in. Figure 1 As shown, the combined use of the above structures can effectively reduce the contact area between the molten metal and the air during the entire process of taking and standing still of the molten metal, thereby reducing the amount of metal slag generated by the contact between the aluminum alloy and the air. And during the process of the pouring cup body 4 taking the molten aluminum alloy, the generated metal slag is squeezed, thus reducing the space occupied by the metal slag in the melting furnace body 5 and facilitating the fishing out of the metal slag from the melting furnace body 5. Moreover, the simple structure and the combined use of the structures further make the use effect of the device better, making the device more practical and convenient for popularization and use.

[0040] As Figures 4 to 9As shown, the cross-section of the first pressing plate 6 is L-shaped, so that the side wall and the bottom of the first pressing plate 6 can be in close contact with the inner wall and the bottom of one side of the furnace body 5. The second pressing plate 7 and the connecting plate 8 are integrally formed, and the stability of the integral structure is better, which is convenient for the two structures to deform together. A fixing frame 13 is installed on one side of the furnace body 5. A first rotating shaft 14 is rotatably connected to the top of the fixing frame 13. A limiting groove 15 is formed at the bottom of the first pressing plate 6. A pressing piece 10 with a shape adapted to that of the limiting groove 15 is provided at the bottom of the furnace body 5. A first connecting strip 11 is fixedly connected to the top of the pressing piece 10. A second connecting strip 12 is fixedly connected to the top of the first connecting strip 11. The first connecting strip 11 and the second connecting strip 12 are integrally formed. The structure formed by the first connecting strip 11 and the second connecting strip 12 is Y-shaped. By bringing the first connecting strip 11 and the second connecting strip 12 into contact with the first rotating shaft 14 and using the first rotating shaft 14 to limit the two sides of the first connecting strip 11 and the second connecting strip 12, and then clamping the fixed rod 9 by a mechanical clamping mechanism. The mechanical clamping mechanism is an existing mature technology, and its working principle and specific structure will not be elaborated here. When the mechanical clamping mechanism takes out the connecting plate 8 and the second pressing plate 7 and the first pressing plate 6 below it from the furnace body 5 together, the pressing piece 10 moves away from the bottom of the furnace body 5, and the first connecting strip 11 and the second connecting strip 12 move along the first rotating shaft 14. And by using the principle that the rolling friction is relatively small, the movement of the first connecting strip 11 and the second connecting strip 12 is made more smooth. And by using the pressing piece 10 and the limiting groove 15 with adapted shapes, when the first pressing plate 6 and the second pressing plate 7 are placed in the furnace body 5, the pressing piece 10 is aligned with the limiting groove 15. During the downward movement of the first pressing plate 6 and the second pressing plate 7, the pressing piece 10 is pressed to the bottom of the furnace body 5, so that the pressing piece 10 drives the first connecting strip 11 and the second connecting strip 12 to move along the first rotating shaft 14. And the above structure is simple, and the coordinated use of the structures can further make the use effect of the metal casting slag pressing mechanism better, effectively improving the practicability of the device.

[0041] Furthermore, a first weakening portion 17 is provided on the connecting plate 8, which can cause the first weakening portion 17 to deform first from the first weakening portion 17 under the action of an external force. A guiding portion 18 is provided on the top of the connecting plate 8, which can use the guiding of the guiding portion 18 to move the pouring cup body 4 towards the melting furnace body 5, so that the deformation of the connecting plate 8 drives the second pressing plate 7 to deform towards the first pressing plate 6. An extrusion portion 19 is provided on one side of the connecting plate 8 close to the guiding portion 18. By using the cooperation of the extrusion portion 19 and the guiding portion 18, the connecting plate 8 further drives the second pressing plate 7 to quickly deform towards the first pressing plate 6, so that the second pressing plate 7 cooperates with the first pressing plate 6 to extrude the internal metal slag. Second weakening portions 21 are arranged annularly and equidistantly on the second pressing plate 7, making it easier for the second pressing plate 7 to deform from the second weakening portions 21 under the action of an external force. A third weakening portion 22 is provided on the top of the second pressing plate 7. Through the setting of the third weakening portion 22, it is further easier for the connection between the second pressing plate 7 and the connecting plate 8 to generate a bending deformation. The cooperation of the structures enables the connecting plate 8, the second pressing plate 7, and the first pressing plate 6 to quickly extrude the metal slag between the first pressing plate 6 and the second pressing plate 7, reducing the space occupied by the metal slag, and the structure is simple. The cooperation of the structures further makes the use effect of the metal casting slag pressing mechanism better.

[0042] As Figures 3 to 5 and Figures 10 to 12 shown, the metal casting slag collecting mechanism includes a collecting box 23 installed on one side of the casting device main body 1. A collecting cavity 24 is opened in the collecting box 23. A baffle body 25 is installed in the collecting cavity 24. Two second rotating shafts 33 are installed on both sides of the top of the collecting box 23. A cover plate 28 is rotatably connected to the side of the second rotating shaft 33 away from the collecting box 23. A connecting piece 29 is fixedly connected to the top of the cover plate 28. As Figure 10 shown, there are two baffle bodies 25. The bottom of the baffle body 25 is fixed to the bottom inner wall of the collecting box 23. Two adsorption blocks 26 are installed on both inner walls of the collecting box 23. The side of the adsorption block 26 close to the center of the collecting box 23 is arc-shaped. A vibration machine body 27 is installed on one side of the collecting box 23. As Figure 10One end of the second connecting strip 12 away from the pressing piece 10 is fixedly connected to the top of the collection box 23. There are two second connecting strips 12 and two collection boxes 23. There are two connecting pieces 29. One side of a connecting piece 29 is fixed on the cover plate 28, and the other side is fixed on the inner wall of the collection box 23. When in the natural state, the connecting piece 29 pulls the cover plate 28 to be unfolded in an inclined shape. When the first pressing plate 6 and the second pressing plate 7 press the pressing piece 10 against the bottom of the furnace body 5, the first connecting strip 11 and the second connecting strip 12 drive the two cover plates 28 to close. At this time, the connecting piece 29 is stretched to generate a certain elastic deformation. Through the cooperation of the above structures, when the first pressing plate 6 and the second pressing plate 7 are taken out of the furnace body 5, the cover plate 28 naturally unfolds. When the first pressing plate 6 and the second pressing plate 7 are put into the furnace body 5 again, the first connecting strip 11 and the second connecting strip 12 pull the cover plate 28 to make the cover plate 28 close, so as to facilitate the pouring of metal slag into the collection box 23 for collection. At the same time, when the metal slag does not need to be collected, the cover plate 28 is used to close the top of the collection box 23. And when the metal slag is poured into the collection box 23, the metal slag first falls on the inclined cover plate 28. At the same time, the vibration machine body 27 is started to make the collection box 23 and the cover plate 28 thereon vibrate, so that the metal slag slowly and evenly falls into the collection cavity 24. When the metal slag passes near the adsorption block 26, the magnetizable metal is adsorbed by the adsorption block 26. When the adsorption block 26 adsorbs a certain amount of metal slag, the vibration machine body 27 makes the adsorption block 26 shake off the excess metal slag on it and collect it in the cavity formed by a baffle body 25 and the collection box 23, and the other unadsorbed metal is collected in the cavity formed by the two baffle bodies 25 and the collection box 23. And the above structure is relatively simple, and the cooperation between the structures further makes the use effect of the device better.

[0043] Furthermore, recesses 32 are equidistantly provided on the cover plate 28, and the recesses 32 are used to increase the surface area of the top of the cover plate 28, and the surface of the cover plate 28 is made rougher, so that the metal slag contacts the cover plate 28 to increase the friction between the two. The side of the cover plate 28 away from the collection box 23 is serrated, so that the two cover plates 28 can be better meshed and closed. A handle is installed on the outer wall of one side of the top of the cover plate 28, which is convenient for manual assistance of the machine to manually open the cover plate 28 under special circumstances. A fourth weakened portion 31 is provided on the connecting piece 29, so that the connecting piece 29 is more easily deformed from the fourth weakened portion 31 under the action of external force. Lightweight slag is equidistantly provided on the connecting piece 29. The groove 30 further enhances the deformation ability of the connecting piece 29 and reduces the mass of the connecting piece 29 by opening the lightweight groove 30. The pressing sheet 10 and the first connecting strip 11 are both made of three-dimensional graphene material or carbon nanotube reinforced composite material, which has good high temperature resistance, and the material itself has good elastic deformation ability. The specific material composition of the above components is not limited to carbon nanotube reinforced composite material, three-dimensional graphene material and high-temperature alloy composite material, etc., as long as its high temperature resistance is greater than the temperature in the furnace body 5 and has good deformation ability, the above structure is relatively simple, and the coordinated use of the structures further makes the use effect of the device better.

[0044] The working principle of the technical solution provided by the present invention is as follows:

[0045] When in use, the first pressing plate 6 and the second pressing plate 7 are placed in the furnace body 5. When placed, the pressing sheet 10 is aligned with the limiting groove 15. During the downward movement of the first pressing plate 6 and the second pressing plate 7, the pressing sheet 10 is pressed to the bottom of the furnace body 5, so that the pressing sheet 10 drives the first connecting strip 11 and the second connecting strip 12 to move along the first rotating shaft 14. When the first pressing plate 6 and the second pressing plate 7 press the pressing sheet 10 tightly against the bottom of the furnace body 5, the first connecting strip 11 and the second connecting strip 12 drive the two cover plates 28 to close. At this time, the connecting sheet 29 is stretched to produce a certain elastic deformation, and then the mechanical arm body 2 is started to control the mechanical arm support arm 3, and the guide of the connecting plate 8 is used. The robot arm 3 and the pouring cup body 4 are moved closer to the furnace body 5, and the side wall of the robot arm 3 is in direct contact with the connecting plate 8. When the pouring cup body 4 moves toward the furnace body 5 along the guide of the connecting plate 8, the fixing rod 9 does not deform during the use of the device. The connecting plate 8 is deformed by the force and pulls the second pressure plate 7 to deform together, so that the second pressure plate 7 is deformed and moved toward the first pressure plate 6. The film 16 on the top of the first pressure plate 6 and the second pressure plate 7 is squeezed and deformed accordingly, so that during the deformation of the connecting plate 8 and the second pressure plate 7, the cavity space formed by the second pressure plate 7 and the first pressure plate 6 becomes smaller, and the metal slag generated inside is squeezed.

[0046] Specifically, liquid outlets are equidistantly arranged at the bottom of the first pressing plate 6. When the first pressing plate 6 and the second pressing plate 7 are attached to the inner wall of the melting furnace body 5, the liquid level of the molten metal inside both of them is lower than the height of the overflow port 20. When the pouring cup body 4 presses the connecting plate 8 and the second pressing plate 7 and moves towards the melting furnace body 5 until it is close to the overflow port 20, the first pressing plate 6 and the second pressing plate 7 squeeze the molten liquid inside them, causing the liquid level inside to rise close to the overflow port 20. Then, control the robotic arm main body 2 to adjust the angle and position of the pouring cup body 4 to align with the overflow port 20. Subsequently, control the robotic arm main body 2 again to further squeeze and deform the second pressing plate 7 towards the first pressing plate 6 by the pouring cup body 4, making the cavity space formed between the first pressing plate 6 and the second pressing plate 7 further smaller, so that the molten metal inside flows out from the overflow port 20 and is caught by the pouring cup body 4. Continuously squeeze the second pressing plate 7 until the pouring cup body 4 contains a sufficient amount of molten metal, then stop squeezing the second pressing plate 7. Then control the robotic arm main body 2 to move the pouring cup body 4 away from the second pressing plate 7 and move it away from the melting furnace body 5 to take it out. The second pressing plate 7 and the connecting plate 8 that are released from the external force rebound to the initial state (as Figure 1 shown). The combined use of the above structures can effectively reduce the contact area between the molten metal and the air during the entire process of scooping up or statically placing the molten metal, thereby reducing the amount of metal slag generated by the contact between the aluminum alloy and the air.

[0047] When the amount of metal slag between the first pressing plate 6 and the second pressing plate 7 reaches a certain level, use the mechanical clamping mechanism to clamp the fixing rod 9. The mechanical clamping mechanism is an existing mature technology, and its working principle and specific structure will not be elaborated here too much. The mechanical clamping mechanism takes out the connecting plate 8, the second pressing plate 7 below it, and the first pressing plate 6 together from the melting furnace body 5. During this period, use the robotic arm support arm 3 to squeeze the second pressing plate 7, making the space formed inside the first pressing plate 6 and the second pressing plate 7 smaller, and then squeezing the aluminum alloy liquid inside to leak out from the overflow port 20 and the bottom of the first pressing plate 6 into the melting furnace body 5. After discharging as much aluminum alloy liquid as possible into the melting furnace body 5, move the first pressing plate 6 and the second pressing plate 7 towards the collection box 23, and at the same time release the squeezing of the second pressing plate 7 by the robotic arm support arm 3. When the first pressing plate 6 and the second pressing plate 7 are taken out, affected by the restoring force of the connecting piece 29, the cover plate 28 unfolds downward, so that the pressing piece 10 moves away from the bottom of the melting furnace body 5. The first connecting strip 11 and the second connecting strip 12 move along the first rotating shaft 14, and then the cover plate 28 unfolds naturally. Control the clamping mechanism to tilt the first pressing plate 6 and the second pressing plate 7 so that the metal slag inside them falls on the inclined cover plate 28.

[0048] Meanwhile, start the vibrator body 27 to vibrate the collection box 23 and the cover plate 28 thereon, so that the metal slag falls into the collection cavity 24 more evenly and slowly. When the metal slag passes near the adsorption block 26, the magnetically attracted metal is adsorbed by the adsorption block 26. When the adsorption block 26 adsorbs a certain amount of metal slag, the vibrator body 27 causes the adsorption block 26 to shake off the excess metal slag on it and collect it in the cavity formed by a baffle body 25 and the collection box 23. The other unadsorbed metal is collected in the cavity formed by two baffle bodies 25 and the collection box 23. After collecting the metal slag collected in the first pressing plate 6 and the second pressing plate 7, bring the first pressing plate 6 and the second pressing plate 7 close to the cover plate 28 and fit them with the cover plate 28. Start the vibrator body 27 to make the cover plate 28 drive the first pressing plate 6 and the second pressing plate 7 to vibrate, and shake off the metal slag residues on the surfaces of the first pressing plate 6 and the second pressing plate 7 into the collection cavity 24 as much as possible. And when it is necessary to clean the pouring cup body 4, bring the robotic arm boom 3 close to the cover plate 28, start the vibrator body 27, and use vibration to quickly remove the residues on the surface of the pouring cup body 4. Then, put the first pressing plate 6 and the second pressing plate 7 back into the furnace body 5. When putting the first pressing plate 6 and the second pressing plate 7 back, align the pressing piece 10 with the limiting groove 15, press down the pressing piece 10 with the first pressing plate 6, and the first connecting strip 11 and the second connecting strip 12 move along the first rotating shaft 14. The second connecting strip 12 pulls the cover plate 28 to close upward, and the connecting piece 29 is stretched again. The combined use of the structures makes the working efficiency of the continuous casting of aluminum alloy pistons higher, and the structure of the device is simple and easy to use.
