Description

Technical Field

[0001] This application relates to the field of casting production robotic arms, and particularly to a casting production and pouring robotic arm. Background Art

[0002] Castings are metal formed objects obtained by various casting methods. During the production process of castings, robotic arms are usually used to pour liquid metal into molds. Subsequently, after subsequent processing means such as cooling and grinding, castings with a certain shape, size, and performance are obtained. In order to improve the production efficiency of castings, continuous automatic feeding of liquid metal and the mold can be carried out to increase the pouring speed of castings.

[0003] In existing casting production robotic arms, such as the Chinese patent with the publication number CN 210755063 U, which discloses an industrial production die-casting product picking robotic arm. Specifically, when using the industrial production die-casting product picking robotic arm, the first motor drives the support arm to rotate through the first connecting plate and adjusts to the corresponding angle. The first electric push rod pushes the first connecting block to move to the vertical position corresponding to the mechanical gripper for the product. The second electric push rod pushes the second connecting block to move in the vertical direction. The second motor drives the second fixed block to rotate through the second connecting plate and adjusts the mechanical gripper to the corresponding position to be picked. The cold air blower motor drives the cold air blower, and the cold air passes through the ventilation pipe and blows towards the product through the air blowing gun head to cool the product. The third electric push rod drives the third fixed block to move. Through the transmission connection of the connecting rod and the link, it will drive the mechanical gripper to pick up the product. The clamping pad arranged on the mechanical gripper will protect the product and prevent scratches generated during the clamping of the mechanical gripper. The entire process includes cooling and picking. For some die-casting products that are not fully cooled, the cooling mechanism will cool the product more deeply, reducing the time required to wait for cooling before picking, more effectively protecting the product, and preventing problems such as scratches and pits being clamped out by the gripper due to incomplete cooling. At the same time, it also saves time and effectively improves production efficiency.

[0004] The above-mentioned prior art can also achieve the production function of castings. However, on the one hand, the above-mentioned prior art can only pick up die-casting products during the production process of castings and cannot achieve the function of pouring liquid metal into the casting mold; on the other hand, during the production process of castings, the above-mentioned prior art cannot achieve the function of filtering and removing impurities in the liquid metal. The impurities doped in the liquid metal are likely to cause a porous phenomenon in the finished casting products. Based on this, there is still room for improvement in existing casting production robotic arms. Summary of the Invention

[0005] In order to be able to achieve the function of automatically and continuously pouring the casting model, and at the same time be able to filter the impurities in the liquid metal to prevent the impurities in the liquid metal from causing the cast product after pouring to have a porous phenomenon.

[0006] A casting production pouring robotic arm provided by this application adopts the following technical solutions:

[0007] A casting production pouring robotic arm includes: a bottom plate frame, which is of a rectangular structure, and a conveying conveyor belt is installed on the right side of the upper end of the bottom plate frame, and casting models are evenly placed on the conveying conveyor belt; a rotating module, which is of an annular structure, and the rotating module is installed on the left side of the upper end of the bottom plate frame; a pouring cylinder, which is of a cylindrical hollow structure, and the pouring cylinders are evenly placed on the rotating module, and the pouring cylinders are used to store liquid metal, mounting seats are symmetrically installed on the pouring cylinder, and baffles are symmetrically installed on the outer wall of the pouring cylinder; a feeding frame, which is installed behind the rotating module, and the feeding frame is used to feed liquid metal into the pouring cylinder; a pouring robotic arm, which is installed in the middle of the rotating module; a pouring module, which is installed at the lower end of the pouring robotic arm, and the pouring module cooperates with the pouring robotic arm to drive the pouring cylinder to pour liquid metal into the casting model, and the baffle cooperates with the pouring module.

[0008] By adopting the above technical solutions, when casting production is required, the feeding frame evenly injects molten liquid metal into the pouring cylinder, and then the rotating module drives the pouring cylinder to rotate counterclockwise. When the pouring cylinder moves to the lower end of the pouring module, the pouring robotic arm drives the pouring module to move downward. The pouring module clamps the mounting seats at both ends of the pouring cylinder and filters the impurities floating on the upper layer of the liquid metal in the pouring cylinder; after the filtering is completed, the pouring robotic arm drives the pouring cylinder to move to the right, and then the lower end of the rotating module presses the baffles symmetrically installed on the outer wall of the pouring cylinder to the left, so that the pouring cylinder is turned to the left by a certain angle, thereby injecting the liquid metal in the pouring cylinder into the casting model, and then completing the pouring function of the casting.

[0009] Preferably, the rotating module includes an annular frame and a rotating disk. The annular frame is installed on the left side of the upper end of the bottom plate frame. An annular groove is provided in the middle of the annular frame, and a rotating disk is installed in the annular groove. Bases are evenly installed on the rotating disk, and pouring cylinders are placed on the bases.

[0010] By adopting the above technical solutions, after the feeding frame injects liquid metal into the pouring cylinder, the rotating disk drives the annular frame to rotate counterclockwise, and the pouring cylinders evenly placed on the upper end of the annular frame rotate with the annular frame. When the pouring cylinder moves to the lower end of the pouring module, the rotating disk stops rotating, which is beneficial for the pouring robotic arm to drive the pouring module to filter the impurities in the pouring cylinder and drive the pouring cylinder to inject liquid metal into the casting model; after the pouring is completed, the pouring robotic arm drives the pouring cylinder to reset, and the rotating disk drives the pouring cylinder to continue rotating counterclockwise, so as to realize the continuous automatic pouring of the casting.

[0011] Preferably, the pouring robotic arm includes a threaded rod, a slider, a fixed frame, a pushing cylinder, and a sliding frame. A mechanical frame is installed in the middle of the annular frame. Above the middle of the mechanical frame is provided a chute, in which the threaded rod is installed. Inside the side wall of the chute is installed a first motor, and the output shaft of the first motor is connected to the end of the threaded rod. The slider is installed on the threaded rod by means of screw thread matching. A fixed frame is installed at the right end of the slider. A sliding frame is slidably arranged on the fixed frame. Pushing cylinders are symmetrically installed in the middle of the fixed frame, and the ends of the pushing cylinders are connected to the sliding frame. Reeling rollers are symmetrically installed on the mechanical frame, and steel wires are reeled on the reeling rollers. The ends of the steel wires are connected to the front and back sides of the sliding frame.

[0012] By adopting the above technical solution, when the rotating module drives the pouring cylinder to move to the lower end of the pouring module, start the first motor, and the rotation of the threaded rod drives the slider, the fixed frame and the sliding frame to move downward, which is conducive to the pouring module clamping the pouring cylinder; when the liquid metal impurities in the pouring cylinder are filtered out, the pushing cylinder pushes the sliding frame to the right, which is conducive to the pouring module driving the pouring cylinder to pour the liquid metal into the casting mold; after pouring is completed, the pushing cylinder drives the sliding frame to reset to the left, and the reverse rotation of the threaded rod drives the slider and the fixed frame to reset upward, so as to clamp the subsequent pouring cylinder.

[0013] Preferably, the pouring module includes an installation sleeve, a clamping unit, a filtering unit, a cleaning unit, and a telescopic cylinder. The installation sleeve is installed at the lower end of the sliding frame. Clamping units are symmetrically installed at the lower end of the installation sleeve. The cleaning unit is installed in the middle of the installation sleeve. A telescopic cylinder is installed on the inner wall of the installation sleeve. An electric turntable one is installed at the outer end of the telescopic cylinder. The filtering unit is installed at the end of the telescopic cylinder, and the filtering unit is matched with the lower end of the cleaning unit.

[0014] By adopting the above technical solution, when the rotating module drives the pouring cylinder to move to the lower end of the installation sleeve, the pouring robotic arm drives the installation sleeve to move downward, the clamping unit clamps the outer end of the pouring cylinder, and then the telescopic cylinder pushes the filtering unit downward, so that the filtering unit moves to the middle of the pouring cylinder to filter the impurities floating on the upper end of the liquid metal. After filtering is completed, the telescopic cylinder drives the filtering unit to move upward, and the cleaning unit fully cleans the surface of the filtering unit.

[0015] Preferably, the clamping unit includes an installation plate, a telescopic rod, and a turning plate. The installation plate is installed at the lower end of the installation sleeve. The telescopic rod is installed inside the side wall of the installation plate. A bearing seat is installed at the end of the telescopic rod. A rotating shaft is installed at the lower end of the installation sleeve through a pin shaft, and the rotating shaft is connected to the output shaft of the second motor. A turning plate is installed on the rotating shaft, and the turning plate is matched with a baffle installed on the pouring cylinder.

[0016] By adopting the above technical solution, when the rotation module drives the pouring cylinder to move to the lower end of the installation sleeve, the pouring robotic arm drives the installation sleeve to move downward. When the telescopic rod moves to be flush with the installation seat, the pouring robotic arm stops moving, and the end of the telescopic rod extends into the installation seat to clamp the pouring cylinder. After the filtering unit finishes filtering the impurities in the pouring cylinder, the pouring robotic arm drives the installation sleeve and the pouring cylinder as a whole to move to the right. When the pouring cylinder moves to the left end of the casting model, the second motor drives the turning plate to turn to the left, so as to squeeze the baffle on the pouring cylinder to the left, causing the pouring cylinder to turn to the left, and successfully pouring the liquid metal in the pouring cylinder into the casting model. After pouring is completed, the second motor drives the turning plate to slowly reset to the right, and at the same time the pouring robotic arm drives the installation sleeve to reset to the left, which is beneficial for the telescopic rod to clamp the subsequent pouring cylinder.

[0017] Preferably, the filtering unit includes an electric push rod, a telescopic frame, a rack plate and a filtering mechanism. A connecting frame is installed at the end of the telescopic cylinder. A filtering mechanism is installed at the lower end of the connecting frame. A telescopic groove is provided in the middle of the connecting frame. The telescopic groove is internally connected to the filtering mechanism. An electric push rod is installed on the inner wall of the telescopic groove. Rack plates are evenly installed on the telescopic frame, and the rack plates are meshed with the inner end of the filtering mechanism.

[0018] By adopting the above technical solution, when the rotation module drives the pouring cylinder to move to the lower end of the installation sleeve, the telescopic cylinder drives the filtering mechanism to move downward until the filtering mechanism extends into the pouring cylinder. Subsequently, the electric push rod pushes the telescopic frame downward, so that the inner end of the filtering mechanism meshes with the rack plate, thereby realizing the function of the outer end of the filtering mechanism turning 90 degrees, which is beneficial for the filtering mechanism to filter impurities. After the filtering mechanism finishes turning, the telescopic cylinder pulls the filtering mechanism upward, so as to successfully filter the impurities on the upper layer of the liquid metal to the upper end of the filtering mechanism. Subsequently, the first electric turntable drives the telescopic cylinder and the filtering mechanism to rotate horizontally to realize the function of fully filtering impurities. After filtering is completed, the telescopic cylinder drives the filtering mechanism to move upward to the middle of the cleaning unit. Subsequently, the cleaning unit drives the filtering mechanism to rotate a certain angle and fully cleans the impurities on the upper end of the filtering unit. After cleaning is completed, the telescopic cylinder pushes the filtering mechanism downward to reset, and the electric push rod pulls the telescopic frame upward. The inner end of the filtering mechanism meshes with the rack plate, and the outer end of the filtering mechanism turns 90 degrees in the reverse direction to reset, which is beneficial for subsequent filtering of impurities in the pouring cylinder.

[0019] Preferably, the filtering mechanism includes a rotating frame, a sector frame, a filter screen frame, a rotating shaft and a gear. A rotating frame is installed at the lower end of the connecting frame. The rotating frame is a cylindrical hollow structure. Rotating shafts are evenly installed on the rotating frame through bearings. A gear is installed at the inner end of the rotating shaft. The gear is meshed with the rack plate. A sector frame is installed at the outer end of the rotating shaft. The cross section of the sector frame is an L-shaped structure. The filter screen frame is installed on the sector frame by means of plug-in fit.

[0020] By adopting the above technical solution, when filtering impurities in the liquid metal, the telescopic cylinder drives the rotating frame and the filter screen frame to extend into the pouring cylinder. Subsequently, the electric push rod pushes the telescopic frame downward, driving the rack plate to engage with the gear, so that the sector frame flips 90 degrees to the horizontal state, which is conducive to the filter screen frame filtering the impurities floating on the upper end of the liquid metal. The telescopic cylinder drives the rotating frame and the sector frame to move up and down reciprocally, so as to filter the impurities to the upper end of the filter screen frame. Subsequently, the first electric turntable drives the telescopic cylinder and the rotating frame to rotate a certain angle, which is conducive to the filter screen frame filtering the impurities sufficiently. After the filtering is completed, the telescopic cylinder drives the rotating frame to move upward to the middle of the cleaning unit. The middle part of the cleaning unit inserts into the filter screen frame. Subsequently, the cleaning unit drives the filter screen frame to rotate a certain angle and cleans the surface of the filter screen frame. The cleaned impurities fall on the middle part of the cleaning unit, so as to collect the impurities.

[0021] Preferably, insertion holes are symmetrically arranged on the sector frame, insertion blocks matched with the insertion holes are installed on the filter screen frame, and positioning holes matched with the cleaning unit are symmetrically arranged on the filter screen frame.

[0022] By adopting the above technical solution, before filtering the impurities, the insertion blocks on the filter screen frame are inserted into the holes on the sector frame, so as to realize the fixing function of the filter screen frame. After the impurities are filtered, the telescopic cylinder drives the filter screen frame to move upward to the middle of the cleaning unit. The cleaning unit inserts into the positioning holes on the filter screen frame, which is conducive to the cleaning unit driving the filter screen frame to rotate a certain angle, so as to accurately and sufficiently clean the surface of the filter screen frame.

[0023] Preferably, the cleaning unit includes a first mounting frame, a second electric turntable, a cleaning frame, a second mounting frame and a collection frame. A first mounting frame is installed above the middle of the installation sleeve. An annular groove is arranged at the lower end of the first mounting frame. A second electric turntable is installed in the annular groove. Cleaning frames are evenly installed at the lower end of the second electric turntable. Insertion rods matched with the positioning holes are installed on the cleaning frames. The cleaning frames are matched with the sector frame. A vibrating plate is installed at the lower end of the cleaning frames. A second mounting frame is installed below the middle of the installation sleeve. Through grooves are evenly arranged on the second mounting frame. The second mounting frame is matched with the sector frame. Collection grooves are evenly arranged on the second mounting frame. A collection frame is detachably installed in the collection grooves.

[0024] By adopting the above technical solution, after the filtering mechanism finishes filtering the impurities, the telescopic cylinder drives the filtering mechanism to move upward. The filtering mechanism enters between the first mounting frame and the second mounting frame through the second mounting frame. At this time, the insertion rods installed at the lower end of the cleaning frame are inserted into the positioning holes on the filter screen frame, so that the cleaning frame and the filter screen frame form an integral body. Subsequently, the second electric turntable drives the cleaning frame to rotate a certain angle, so that the filter screen frame just stops above the collection frame. At this time, the lower end surface of the vibrating plate is closely attached to the upper end surface of the filter screen frame. Subsequently, the vibrating plate vibrates the filter screen frame, so that the impurities on the filter screen frame accurately fall into the collection frame, so as to collect the impurities.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The present invention is provided with a filtering unit. When the rotating module drives the pouring cylinder to move to the lower end of the mounting sleeve, the telescopic cylinder drives the filtering mechanism to move downward until the filtering mechanism extends into the pouring cylinder. Subsequently, the electric push rod pushes the telescopic frame downward, so that the inner end of the filtering mechanism meshes with the rack plate, thereby realizing the function of the outer end of the filtering mechanism flipping 90 degrees, which is conducive to the filtering mechanism filtering impurities; after the filtering mechanism flips, the telescopic cylinder pulls the filtering mechanism upward, so that the impurities on the upper layer of the liquid metal are successfully filtered to the upper end of the filtering mechanism. Subsequently, the electric turntable 1 drives the telescopic cylinder and the filtering mechanism to rotate horizontally, realizing the full filtering function of the impurities; after filtering, the telescopic cylinder drives the filtering mechanism to move upward to the middle of the cleaning unit. Subsequently, the cleaning unit drives the filtering mechanism to rotate a certain angle and fully cleans the impurities at the upper end of the filtering unit; after cleaning, the telescopic cylinder pushes the filtering mechanism downward to reset, the electric push rod pulls the telescopic frame upward, and the inner end of the filtering mechanism meshes with the rack plate, so that the outer end of the filtering mechanism flips 90 degrees in the opposite direction to reset, which is conducive to subsequent filtering of impurities in the pouring cylinder.

[0027] 2. The present invention is provided with a filtering mechanism. When filtering impurities in liquid metal, the telescopic cylinder drives the rotating frame and the filter screen frame to extend into the pouring cylinder. Subsequently, the electric push rod pushes the telescopic frame downward, driving the rack plate to mesh with the gear, so that the sector frame flips 90 degrees to a horizontal state, which is conducive to the filter screen frame filtering the impurities floating on the upper layer of the liquid metal; the telescopic cylinder drives the rotating frame and the sector frame to move up and down reciprocally, so that the impurities are filtered to the upper end of the filter screen frame. Subsequently, the electric turntable 1 drives the telescopic cylinder and the rotating frame to rotate a certain angle, which is conducive to the filter screen frame fully filtering the impurities; after filtering, the telescopic cylinder drives the rotating frame to move upward to the middle of the cleaning unit. The middle part of the cleaning unit inserts into the filter screen frame, and then the cleaning unit drives the filter screen frame to rotate a certain angle and cleans the surface of the filter screen frame. The cleaned impurities fall on the middle part of the cleaning unit, thereby collecting the impurities.

[0028] 3. The present invention is provided with a cleaning unit. After the filtering mechanism filters impurities, the telescopic cylinder drives the filtering mechanism to move upward.

Subsequently, the electric turntable 2 drives the cleaning frame to rotate a certain angle, so that the filter screen frame just stops above the collection frame. At this time, the lower end surface of the vibrating plate is in close contact with the upper end surface of the filter screen frame. Subsequently, the vibrating plate vibrates the filter screen frame, so that the impurities on the filter screen frame accurately fall into the collection frame, thereby collecting the impurities.

Detailed implementation manners

[0040] The following will Figures 1-9 make a further detailed description of the present application.

[0041] An embodiment of the present application discloses a casting production pouring robotic arm, which can realize the function of automatically and continuously pouring a casting model, and can filter impurities in the liquid metal to prevent the casting product after pouring from being porous due to impurities in the liquid metal.

[0042] Referring to Figure 1 , a casting production pouring robotic arm includes: a bottom plate frame 1, which is a rectangular structure. A conveyor belt 11 is installed on the upper right side of the bottom plate frame 1, and casting models are evenly placed on the conveyor belt 11; a rotating module 2, which is a ring structure and is installed on the upper left side of the bottom plate frame 1; a pouring cylinder 3, which is a cylindrical hollow structure and is evenly placed on the rotating module 2. The pouring cylinder 3 is used to store liquid metal. Mounting seats are symmetrically installed on the pouring cylinder 3, and baffles are symmetrically installed on the outer wall of the pouring cylinder 3; a feeding frame 4 is installed behind the rotating module 2, and the feeding frame 4 is used to feed liquid metal into the pouring cylinder 3; a pouring robotic arm 5 is installed in the middle of the rotating module 2; a pouring module 6 is installed at the lower end of the pouring robotic arm 5. The pouring module 6 and the pouring robotic arm 5 cooperate with each other to drive the pouring cylinder 3 to pour liquid metal into the casting model, and the baffle cooperates with the pouring module 6.

[0043] During the actual use process, when casting production is required, the feeding frame 4 evenly injects molten liquid metal into the pouring cylinder 3. Subsequently, the rotating module 2 drives the pouring cylinder 3 to rotate counterclockwise. When the pouring cylinder 3 moves to the lower end of the pouring module 6, the pouring robotic arm 5 drives the pouring module 6 to move downward. The pouring module 6 clamps the mounting seats at both ends of the pouring cylinder 3 and filters the impurities floating on the upper layer of the liquid metal in the pouring cylinder 3 to prevent impurities from being contained in the casting product after production, thus avoiding the appearance of pores; after filtering, the pouring robotic arm 5 drives the pouring cylinder 3 to move to the right. Subsequently, the lower end of the rotating module 2 presses the baffles symmetrically installed on the outer wall of the pouring cylinder 3 to the left, causing the pouring cylinder 3 to turn left by a certain angle, thereby injecting the liquid metal in the pouring cylinder 3 into the casting model, and then completing the pouring function of the casting.

[0044] Referring to Figure 2 , in order to realize the function of driving the pouring cylinder 3 to rotate counterclockwise around the pouring robotic arm 5, a rotating module 2 is provided in this embodiment. The rotating module 2 includes an annular frame 21 and a rotating disk 22. The annular frame 21 is installed on the upper left side of the bottom plate frame 1. An annular groove is provided in the middle of the annular frame 21, and the rotating disk 22 is installed in the annular groove. Bases are evenly installed on the rotating disk 22, and the pouring cylinder 3 is placed on the bases.

[0045] During actual use, after the loading rack 4 injects liquid metal into the pouring cylinder 3, the rotating disk 22 drives the annular rack 21 to rotate counterclockwise. The pouring cylinders 3 evenly placed at the upper end of the annular rack 21 rotate with the annular rack 21. When the pouring cylinder 3 moves to the lower end of the pouring module 6, the rotating disk 22 stops rotating, which is conducive to the pouring robotic arm 5 driving the pouring module 6 to filter the impurities in the pouring cylinder 3 and driving the pouring cylinder 3 to inject liquid metal into the casting mold. After pouring is completed, the pouring robotic arm 5 drives the pouring cylinder 3 to reset, and the rotating disk 22 drives the pouring cylinder 3 to continue rotating counterclockwise, thereby realizing continuous automatic pouring of the casting.

[0046] It should be noted that after the loading rack 4 finishes loading liquid metal, the rotating disk 22 drives the annular rack 21 to rotate counterclockwise. At this time, the liquid metal in the pouring cylinder 3 can be moderately cooled, and at the same time, the impurities in the pouring cylinder 3 can float on the upper layer of the liquid metal, which is conducive to the pouring module 6 filtering and removing the impurities.

[0047] Refer to Figure 2 and Figure 3 In order to be able to realize the function of driving the pouring module 6 to move up, down, left, and right, the pouring robotic arm 5 includes a threaded rod 51, a slider 52, a fixed frame 53, a pushing cylinder 54, and a sliding frame 55. A mechanical frame is installed in the middle of the annular rack 21. A chute is provided above the middle of the mechanical frame. The threaded rod 51 is installed in the chute. A motor one is installed in the side wall of the chute. The output shaft of the motor one is connected to the end of the threaded rod 51. The slider 52 is installed on the threaded rod 51 by means of threaded cooperation. The right end of the slider 52 is installed with a fixed frame 53. A sliding frame 55 is slidably arranged on the fixed frame 53. Pushing cylinders 54 are symmetrically installed in the middle of the fixed frame 53. The ends of the pushing cylinders 54 are connected to the sliding frame 55. Reeling rollers are symmetrically installed on the mechanical frame. Steel wires are reeled on the reeling rollers. The ends of the steel wires are connected to the front and back sides of the sliding frame 55.

[0048] During actual use, when the rotating module 2 drives the pouring cylinder 3 to move to the lower end of the pouring module 6, the motor one is started. The threaded rod 51 rotates to drive the slider 52, the fixed frame 53, and the sliding frame 55 to move downward, which is conducive to the pouring module 6 clamping the pouring cylinder 3. After filtering the impurities in the pouring cylinder 3, the pushing cylinder 54 pushes the sliding frame 55 to the right, which is conducive to the pouring module 6 driving the pouring cylinder 3 to pour the liquid metal into the casting mold. After pouring is completed, the pushing cylinder 54 drives the sliding frame 55 to reset to the left, and the threaded rod 51 rotates in the reverse direction to drive the slider 52 and the fixed frame 53 to reset upward, so as to clamp the subsequent pouring cylinder 3.

[0049] Refer to Figures 2-4 and Figure 8, in order to realize the pouring function of the casting model, the pouring module 6 includes an installation sleeve 61, a clamping unit 62, a filtering unit 63, a cleaning unit 64 and a telescopic cylinder 65. The installation sleeve 61 is installed at the lower end of the sliding frame 55. The clamping unit 62 is symmetrically installed at the lower end of the installation sleeve 61. The cleaning unit 64 is installed in the middle of the installation sleeve 61. The telescopic cylinder 65 is installed on the inner wall of the installation sleeve 61. An electric turntable one is installed at the outer end of the telescopic cylinder 65. The filtering unit 63 is installed at the end of the telescopic cylinder 65. The filtering unit 63 is matched with the lower end of the cleaning unit 64.

[0050] During actual use, when the rotating module 2 drives the pouring cylinder 3 to move to the lower end of the installation sleeve 61, the pouring robotic arm 5 drives the installation sleeve 61 to move downward. The clamping unit 62 clamps the outer end of the pouring cylinder 3. Subsequently, the telescopic cylinder 65 pushes the filtering unit 63 downward, so that the filtering unit 63 moves to the middle of the pouring cylinder 3 to filter the impurities floating on the upper end of the liquid metal. After the filtering is completed, the telescopic cylinder 65 drives the filtering unit 63 to move upward, and the cleaning unit 64 fully cleans the surface of the filtering unit 63.

[0051] Refer to Figure 4 and Figure 8 , in order to realize the clamping function of the pouring cylinder 3, the clamping unit 62 includes a mounting plate 621, a telescopic rod 622 and a turning plate 623. The mounting plate 621 is installed at the lower end of the installation sleeve 61. The telescopic rod 622 is installed inside the side wall of the mounting plate 621. A bearing seat is installed at the end of the telescopic rod 622. A rotating shaft is installed at the lower end of the installation sleeve 61 through a pin shaft. The rotating shaft is connected to the output shaft of the second motor. The turning plate 623 is installed on the rotating shaft. The turning plate 623 is matched with the baffle installed on the pouring cylinder 3.

[0052] During actual use, when the rotating module 2 drives the pouring cylinder 3 to move to the lower end of the installation sleeve 61, the pouring robotic arm 5 drives the installation sleeve 61 to move downward. When the telescopic rod 622 moves to be flush with the mounting seat, the pouring robotic arm 5 stops moving. The end of the telescopic rod 622 extends into the mounting seat to clamp the pouring cylinder 3. When the filtering unit 63 finishes filtering the impurities in the pouring cylinder 3, the pouring robotic arm 5 drives the installation sleeve 61 and the pouring cylinder 3 to move to the right as a whole. When the pouring cylinder 3 moves to the left end of the casting model, the second motor drives the turning plate 623 to turn to the left, so as to squeeze the baffle on the pouring cylinder 3 to the left, making the pouring cylinder 3 turn to the left, so as to successfully pour the liquid metal in the pouring cylinder 3 into the casting model. When the pouring is completed, the second motor drives the turning plate 623 to slowly reset to the right, and at the same time the pouring robotic arm 5 drives the installation sleeve 61 to reset to the left, which is beneficial for the telescopic rod 622 to clamp the subsequent pouring cylinder 3.

[0053] Refer to Figures 5-7, in order to achieve the function of filtering and removing the impurities floating on the upper layer of the liquid metal in the pouring cylinder 3, the filtering unit 63 includes an electric push rod 631, a telescopic frame 632, a rack plate 633 and a filtering mechanism 634. A connecting frame is installed at the end of the telescopic cylinder 65, a filtering mechanism 634 is installed at the lower end of the connecting frame, a telescopic groove is arranged in the middle of the connecting frame, the telescopic groove is communicated with the inside of the filtering mechanism 634, an electric push rod 631 is installed on the inner wall of the telescopic groove, rack plates 633 are uniformly installed on the telescopic frame 632, and the rack plates 633 are meshed with the inner end of the filtering mechanism 634.

[0054] During the actual use process, when the rotating module 2 drives the pouring cylinder 3 to move to the lower end of the installation sleeve 61, the telescopic cylinder 65 drives the filtering mechanism 634 to move downward until the filtering mechanism 634 extends into the pouring cylinder 3. Subsequently, the electric push rod 631 pushes the telescopic frame 632 downward, so that the inner end of the filtering mechanism 634 is meshed with the rack plate 633, thereby realizing the function that the outer end of the filtering mechanism 634 flips 90 degrees, which is beneficial to the filtering mechanism 634 to filter the impurities; after the filtering mechanism 634 finishes flipping, the telescopic cylinder 65 pulls the filtering mechanism 634 upward, so as to successfully filter the impurities on the upper layer of the liquid metal to the upper end of the filtering mechanism 634. Subsequently, the first electric turntable drives the telescopic cylinder 65 and the filtering mechanism 634 to rotate horizontally to achieve the full filtering function of the impurities; after the filtering is completed, the telescopic cylinder 65 drives the filtering mechanism 634 to move upward to the middle of the cleaning unit 64. Subsequently, the cleaning unit 64 drives the filtering mechanism 634 to rotate a certain angle and fully cleans the impurities at the upper end of the filtering unit 63; after the cleaning is completed, the telescopic cylinder 65 pushes the filtering mechanism 634 downward to reset, the electric push rod 631 pulls the telescopic frame 632 upward, and the inner end of the filtering mechanism 634 is meshed with the rack plate 633, so that the outer end of the filtering mechanism 634 flips 90 degrees in the reverse direction to reset, which is beneficial to the subsequent filtering of the impurities in the pouring cylinder 3.

[0055] Refer to Figure 6 , Figure 7 and Figure 9 , the filtering mechanism 634 includes a rotating frame 6341, a sector frame 6342, a filter screen frame 6343, a rotating shaft 6344 and a gear 6345. A rotating frame 6341 is installed at the lower end of the connecting frame. The rotating frame 6341 is a cylindrical hollow structure. Rotating shafts 6344 are uniformly installed on the rotating frame 6341 through bearings. A gear 6345 is installed at the inner end of the rotating shaft 6344. The gear 6345 is meshed with the rack plate 633. A sector frame 6342 is installed at the outer end of the rotating shaft 6344. The cross section of the sector frame 6342 is an L-shaped structure. A filter screen frame 6343 is installed on the sector frame 6342 in a plug-in fit manner.

[0056] During actual use, when filtering impurities in the liquid metal, the telescopic cylinder 65 drives the rotating frame 6341 and the filter screen frame 6343 to extend into the pouring cylinder 3. Subsequently, the electric push rod 631 pushes the telescopic frame 632 downward, driving the rack plate 633 to engage with the gear 6345, so that the sector frame 6342 flips 90 degrees to the horizontal state, facilitating the filter screen frame 6343 to filter the impurities floating on the upper end of the liquid metal; the telescopic cylinder 65 drives the rotating frame 6341 and the sector frame 6342 to reciprocate up and down, thus filtering the impurities to the upper end of the filter screen frame 6343. Subsequently, the first electric turntable drives the telescopic cylinder 65 and the rotating frame 6341 to rotate a certain angle, facilitating the filter screen frame 6343 to filter the impurities sufficiently; after the filtering is completed, the telescopic cylinder 65 drives the rotating frame 6341 to move upward to the middle of the cleaning unit 64. The middle of the cleaning unit 64 inserts into the filter screen frame 6343. Subsequently, the cleaning unit 64 drives the filter screen frame 6343 to rotate a certain angle and cleans the surface of the filter screen frame 6343. The cleaned impurities fall on the middle of the cleaning unit 64, thereby collecting the impurities.

[0057] It should be noted that when filtering impurities, the upper end surface of the liquid metal in the pouring cylinder 3 is located between the upper end surfaces of the sector frame 6342 and the filter screen frame 6343, facilitating the sector frame 6342 to block the impurities to the upper end of the filter screen frame 6343.

[0058] Refer to Figure 7 and Figure 9 As shown in, insertion holes 6346 are symmetrically arranged on the sector frame 6342. Insertion blocks that cooperate with the insertion holes 6346 are installed on the filter screen frame 6343. Positioning holes 6347 that cooperate with the cleaning unit 64 are symmetrically arranged on the filter screen frame 6343.

[0059] During actual use, before filtering impurities, the insertion blocks on the filter screen frame 6343 are inserted into the holes on the sector frame 6342, thus realizing the fixing function of the filter screen frame 6343; after the impurity filtering is completed, the telescopic cylinder 65 drives the filter screen frame 6343 to move upward to the middle of the cleaning unit 64. The cleaning unit 64 inserts into the positioning holes 6347 on the filter screen frame 6343, facilitating the cleaning unit 64 to drive the filter screen frame 6343 to rotate a certain angle, thereby accurately and sufficiently cleaning the surface of the filter screen frame 6343.

[0060] Refer to Figure 5 and Figure 8, in order to realize the function of cleaning the impurities on the surface of the filter screen frame 6343, the cleaning unit 64 includes a first mounting frame 641, a second electric turntable 642, a cleaning frame 643, a second mounting frame 644 and a collection frame 645. Above the middle of the mounting sleeve 61, a first mounting frame 641 is installed. At the lower end of the first mounting frame 641, an annular groove is provided, and a second electric turntable 642 is installed in the annular groove. At the lower end of the second electric turntable 642, cleaning frames 643 are evenly installed. On the cleaning frame 643, a plug rod matching with the positioning hole 6347 is installed. The cleaning frame 643 cooperates with the sector frame 6342. At the lower end of the cleaning frame 643, a vibrating plate is installed. Below the middle of the mounting sleeve 61, a second mounting frame 644 is installed. Through grooves are evenly provided on the second mounting frame 644. The second mounting frame 644 cooperates with the sector frame 6342. Collection grooves are evenly provided on the second mounting frame 644, and a collection frame 645 is detachably installed in the collection grooves.

[0061] During actual use, when the filtering mechanism 634 finishes filtering impurities, the telescopic cylinder 65 drives the filtering mechanism 634 to move upward. The filtering mechanism 634 enters between the first mounting frame 641 and the second mounting frame 644 through the second mounting frame 644. At this time, the plug rod installed at the lower end of the cleaning frame 643 is inserted into the positioning hole 6347 on the filter screen frame 6343, so that the cleaning frame 643 and the filter screen frame 6343 form an integral body. Subsequently, the second electric turntable 642 drives the cleaning frame 643 to rotate a certain angle, so that the filter screen frame 6343 just stops at the upper end of the collection frame 645. At this time, the lower end surface of the vibrating plate is closely attached to the upper end surface of the filter screen frame 6343. Subsequently, the vibrating plate vibrates the filter screen frame 6343, so that the impurities on the filter screen frame 6343 accurately fall into the collection frame 645, thereby collecting the impurities.

[0062] It should be noted that when the telescopic cylinder 65 drives the filtering mechanism 634 to move upward, the evenly arranged sector frame 6342 enters between the first mounting frame 641 and the second mounting frame 644 through the through grooves on the second mounting frame 644, which is beneficial for the cleaning frame 643 to clean the filter screen frame 6343.

[0063] The implementation principle of this embodiment is as follows:

[0064] 1: Rotating feeding of liquid metal. When casting parts need to be produced, the feeding frame 4 evenly injects molten liquid metal into the pouring cylinder 3. Subsequently, the rotating module 2 drives the pouring cylinder 3 to rotate counterclockwise, so as to drive the pouring cylinder 3 filled with liquid metal to the lower end of the pouring module 6, which is beneficial for clamping the pouring cylinder 3.

[0065] 2: Filtration of impurities in liquid metal. When the pouring cylinder 3 moves to the lower end of the pouring module 6, the pouring robotic arm 5 drives the pouring module 6 to move downward. The pouring module 6 clamps the mounting seats at both ends of the pouring cylinder 3 and filters the impurities floating on the upper layer of the liquid metal in the pouring cylinder 3 to prevent the cast products after production from containing impurities, thus avoiding the appearance of porous phenomena.

[0066] 3: Pouring of liquid metal. After filtration, the pouring robotic arm 5 drives the pouring cylinder 3 to move to the right. Subsequently, the lower end of the rotating module 2 squeezes the symmetrically mounted baffles on the outer wall of the pouring cylinder 3 to the left, causing the pouring cylinder 3 to turn left by a certain angle, thereby injecting the liquid metal in the pouring cylinder 3 into the gradual model, and then completing the pouring function of the casting.

[0067] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
