[0002] Casting is a process of melting metal into liquid that meets certain requirements and pouring it into a mold, cooling, solidifying, and cleaning to obtain a casting with a predetermined shape, size, and performance. Because the casting blank is almost formed, it can achieve the purpose of no mechanical processing or a small amount of processing, which reduces costs and reduces production time to a certain extent. It is one of the basic processes in the modern device manufacturing industry.

[0003] After casting, some metal debris will remain in the casting mold, and there will be some casting holes in the casting mold, which will be blocked by the casting material.

[0020] 1. The metal casting machine is provided with a cleaning assembly on one side of the lower die, which includes a cleaning plate, a brush roller, a support arm and an electric slide in sequence, and the electric slide is connected between the moving assemblies. After the casting is taken out, the cleaning assembly is pushed to the top of the lower die by an electric cylinder, and the support arm connected to the cleaning plate is driven by the electric slide to move back and forth horizontally, and the metal residue in the lower die is cleaned and removed by a brush roller, thereby avoiding personnel cleaning and eliminating safety hazards;

[0023] 4. The metal casting machine can ensure that the brush roller and the lower die always keep in contact with each other during the swinging of the casting base by setting a torsion spring and a limit plate. In the initial state of the cleaning plate, the angle between the cleaning plate and the support arm is not less than 90°.

[0024] 5. The metal casting machine, through a device for driving the casting machine base to move on the ground rail, comprises a moving base, a ball screw, an internal thread sleeve and a guide block in sequence. The ball screw rotates, and the guide block drives the moving base by utilizing the rotating connection structure of the internal thread sleeve and the guide block, and the moving base drives the frame to move on the ground rail. The device can adjust the casting station according to molds of different sizes, thereby increasing the application range of the device.

[0025] The parts not involved in the device are the same as the prior art or can be implemented by the prior art. The present invention uses an electric slide to drive the support arm to connect the cleaning plate to move back and forth horizontally, and uses a brush roller to clean and remove the metal residue in the lower mold, avoiding personnel cleaning and eliminating safety hazards; a rotating eccentric structure is used to push the casting machine base to swing around its pin connection position with the frame, so that the cleaning plate and the lower mold are longitudinally reciprocating. In conjunction with the lateral reciprocating movement, the cleaning area is expanded and the cleaning effect is improved; the piston rod slidingly arranged in the air box is linked by a connecting rod and a driving wheel pin at one end of the rotating shaft to squeeze and discharge the gas in the air box, and in conjunction with the booster valve installed in the air nozzle, the impact force of the gas is increased during discharge, and the residue in the recessed area of ​​the lower mold is blown away more effectively; the rotating connection structure of the internal threaded sleeve and the guide block is used, the guide block drives the moving seat, and the moving seat drives the frame to move on the ground rail, so that the device can adjust the casting station according to molds of different sizes, thereby increasing the scope of application of the device.

[0036] Example:

[0037] Reference Figure 1-Figure 7 A high-strength metal casting machine comprises two sets of ground rails 1 and a casting machine base 3 rotatably arranged between the two sets of ground rails 1, an upper mold 4 and a lower mold 5 are arranged on one side of the casting machine base 3, a hydraulic cylinder 24 is fixedly installed on the top of the casting machine base 3, the telescopic rod end of the hydraulic cylinder 24 passes through the casting machine base 3 and extends and is fixed on the upper surface of the upper mold 4, two sets of linear guide rails 26 are symmetrically arranged on one side of the casting machine base 3, and one side of the upper mold 4 is slidably connected to the linear guide rail 26.

[0038] The present embodiment discloses a metal casting machine, which is provided with two groups of ground rails 1. A fixed crossbeam 22 is fixedly connected between the two groups of ground rails 1 to ensure the stability of the overall structure of the ground rails; a casting machine base 3 is slidably installed between the two groups of ground rails 1, and an upper mold 4 and a lower mold 5 are arranged on one side of the casting machine base 3. The hydraulic cylinder 24 is started, and the telescopic rod end of the hydraulic cylinder 24 is used to drive the upper mold 4 to move downward. The lower mold 5 is fixedly installed on one side of the casting machine base 3. Therefore, after the upper mold 4 and the lower mold 5 are pressed together, the coolant is filled and wrapped outside the mold to solidify the metal solution. In this embodiment, high-strength alloy materials are used for high-strength metal casting.

[0039] It should be noted that in this embodiment, two sets of linear guide rails 26 are arranged between the upper mold 4 and the casting machine base 3. When the upper mold 4 is driven by the hydraulic cylinder 24 to move up and down, the linear guide rails 26 are used as a sliding connection structure to ensure smooth up and down movement of the upper mold 4.

[0040] The model of the hydraulic cylinder 24 is preferably HOB100X300. A magnetic ring is disposed outside the hydraulic cylinder 24. The stroke of the telescopic rod is controlled by adjusting the position of the magnetic ring, so that the stroke can be adjusted according to changes in usage conditions.

[0041] A guide sleeve 27 is fixedly mounted on the casting machine base 3 and the upper die 4 , and a guide rod 25 is slidably mounted in the guide sleeve 27 .

[0042] In this embodiment, a guide rod 25 is provided between the casting machine base 3 and the upper mold 4. The guide rod 25 is slidably connected in the guide sleeve 27 to provide a guiding structure for the upper mold 4 during its up and down movement, thereby ensuring that the upper mold 4 and the lower mold 5 are tightly pressed together and high-strength metal is formed without defects.

[0043] The present embodiment also includes a cleaning component that can be moved to the top of the lower mold 5 for reciprocating motion. The cleaning component is arranged between the two sets of ground rails 1 through a moving component. The cleaning component includes a cleaning plate 6 and a brush roller 23 rotatably installed at the bottom of the cleaning plate 6. One end of the cleaning plate 6 is rotatably connected to the support arm 7 through a pin shaft 30. An electric cylinder 39 is fixedly installed at one end of the ground rail 1, and the telescopic rod end of the electric cylinder 39 is fixedly connected to one side of the slider 13.

[0044] In this embodiment, a cleaning component is provided on one side of the casting machine base 3, and the cleaning component is slidably connected to the ground rail 1 through a moving component. After the casting is completed and the formed metal casting is taken out, the electric cylinder 39 is started, and the telescopic rod end of the electric cylinder 39 is used to push the moving component, thereby moving the cleaning plate 6 to the top of the lower mold 5, so that the brush roller 23 at the bottom of the cleaning plate 6 and the lower mold 5 are fitted together for subsequent cleaning of the lower mold 5.

[0045] Specifically, the moving assembly includes two groups of sliders 13, and a wheel axle 15 is connected between the two groups of sliders 13. The wheel axle 15 is rotatably connected to a pulley 14, and the pulley 14 is rotatably connected to the upper surface of the ground rail 1. Slide grooves 16 are provided on both sides of the ground rail 1, and the bottom of the slider 13 is matched with the slide groove 16. There are two groups of electric slides 9 between the sliders 13, and the bottom surface of the support arm 7 is connected to the electric slide 9.

[0046] In this embodiment, a pulley 14 is used to roll against the upper surface of the ground rail 1, and sliders 13 are symmetrically arranged on both sides of the pulley 14. The sliders 13 and the slide grooves 16 are clearance-matched. An electric slide 9 is connected between the sliders 13 on the two sets of ground rails 1, and the cleaning plate 6 is connected to the electric slide 9 through the support arm 7. Starting the electric slide 9 can drive the cleaning plate 6 and the brush roller 23 at the bottom of the cleaning plate 6 to move back and forth laterally on the lower mold 5, so as to clean the metal debris or casting residue remaining in the lower mold 5.

[0047] The model of the electric cylinder 39 is preferably DTLDDG-009, with a rated speed of 41 mm / sec. A magnetic ring is provided on the outside of the electric cylinder 39. By adjusting the position of the magnetic ring, the stroke of the telescopic rod is controlled, so that the stroke can be adjusted according to changes in casting conditions.

[0048] A moving seat 17 is slidably provided on the ground rail 1, and a frame 2 is fixedly installed on the moving seat 17. Both sides of the casting machine base 3 are rotatably connected with two groups of frames 2 respectively.

[0049] In this embodiment, the casting machine base 3 is mounted between two sets of ground rails 1 through the frame 2, so as to ensure that the casting machine base 3 can swing with the pinned position in the frame 2 as a fulcrum.

[0050] A guide block 20 is fixedly installed on one side of the moving seat 17 , a ball screw 18 is connected to the guide block 20 through an internal threaded sleeve 19 , the ball screw 18 is rotatably installed on one side of the ground rail 1 , and one end of the ball screw 18 is transmission-connected to a motor 21 .

[0051] In this embodiment, a device is provided to drive the casting machine base 3 to move on the ground rail 1, including a motor 21 and a ball screw 18 connected to the output shaft end of the motor 21. When the working position of the casting machine base 3 needs to be adjusted, the motor 21 is started to drive the ball screw 18 to rotate. Since the ball screw 18 is connected to the guide block 20, the guide block 20 is slidably arranged in the ground rail 1. Therefore, the guide block 20 drives the moving seat 17 by utilizing the rotating connection structure of the internal threaded sleeve 19 and the guide block 20, and the moving seat 17 drives the frame 2 to move on the ground rail 1.

[0052] It should be noted that a moving seat 17 is provided at the bottom of the frame 2 , and a slider 13 and a pulley 14 are also provided between the moving seat 17 and the ground rail 1 , thereby ensuring that the frame 2 moves smoothly on the ground rail 1 .

[0053] This embodiment also includes a driving assembly for driving the casting machine base 3 to swing circumferentially, and the circumferential swing and cleaning assembly are used for contact friction. The driving assembly includes a rotating shaft 8, which is rotatably installed between two sets of sliders 13, and the rotating shaft 8 is set through the support arm 7. Two sets of eccentric wheels 10 are fixedly installed on the surface of the rotating shaft 8. A push rod 11 is fixedly installed on one side of the casting machine base 3, and a ball head 12 is set at one end of the push rod 11. The ball head 12 and the outer ring of the eccentric wheel 10 are contacted.

[0054] Specifically, when the cleaning plate 6 starts to move back and forth on the lower mold 5 for cleaning, the rotation of the rotating shaft 8 is started. The rotation of the rotating shaft 8 can drive the eccentric wheel 10 on its surface to rotate. Since a push rod 11 with a ball head 12 is provided on one side of the lower mold 5, the ball head 12 is always in contact with the outer ring of the eccentric wheel 10 under the action of the gravity of the entire casting machine base 3. Therefore, when the eccentric wheel 10 rotates, the eccentric moment can be used to push the casting machine base 3 to swing back and forth between the two groups of frames 2, thereby increasing the longitudinal action area of ​​the cleaning plate 6 on the lower mold 5, thereby expanding the cleaning area.

[0055] A torsion spring 28 is provided between the support arm 7 and the cleaning plate 6 and on the surface of the pin shaft 30 , and a limit plate 29 is provided on one side of the support arm 7 , and the inner arc surface of the limit plate 29 is matched with the end surface of the cleaning plate 6 .

[0056] Among them, a ball head 12 is provided at one end of the push rod 11. The ball head 12 is set as a universal rotating structure. It is set at the end of the push rod 11 and is fitted with the outer ring of the eccentric wheel 10 to reduce the contact area, thereby reducing friction and avoiding wear of parts during the fitting and rotation process.

[0057] It should be noted that, since the casting machine base 3 swings during cleaning, in order to ensure that the brush roller 23 and the lower mold 5 always maintain a close fit, a torsion spring 28 is arranged between the cleaning plate 6 and the support arm 7. At the same time, the angle between the cleaning plate 6 and the support arm 7 is not less than 90° in the initial state of the cleaning plate 6. A limit plate 29 is provided for limiting. Only in this way can it be ensured that when the electric cylinder 39 pushes the cleaning plate 6 to the cleaning position, it can prevent the cleaning plate 6 from colliding and interfering with the lower mold 5 when it approaches the casting machine base 3.

[0058] It should be noted that in order to adapt to different types of upper molds 4 and lower molds 5, the rotation of the ball screw 18 is used to drive the frame 2 to move and adapt to the casting station. For larger upper molds 4 and lower molds 5, the size of the cleaning plate 6 needs to be adjusted. In order to reduce the disassembly and assembly of the cleaning components, the cleaning plate 6 and the brush roller 23 can be set as a telescopic structure.

[0059] The ball screw 18 can convert rotational motion into linear motion, thereby improving transmission efficiency. At the same time, it can ensure the positioning accuracy of the casting base 3 after the movement stroke, and finally increase the movement stroke range of the casting base 3 to drive the upper mold 4 and the lower mold 5.

[0060] A debris removal component is provided on one side of the slider 13, and the debris removal component includes an air box 31 and a piston plate 36 slidably installed in the air box 31. The top of the air box 31 is connected to an air outlet pipe 32 through a connecting pipe 38, and the air outlet pipe 32 is connected to a side close to the lower mold 5 with an air nozzle 37.

[0061] Considering that the electric slide 9 drives the cleaning plate 6 and the brush roller 23 at the bottom of the cleaning plate 6 to move back and forth above the lower mold 5, it can not only clean the residue, but also peel off the metal residue adhered to the lower mold 5 during the casting process. However, for some deeper molds, there may still be residues after cleaning. Therefore, in this embodiment, an air box 31 is provided on one side of the casting machine base 3. The piston plate 36 in the air box 31 is extruded to blow the lower mold 5 through the air outlet pipe 32 and the air nozzle 37 in turn, so as to blow out the residue in the recessed area of ​​the lower mold 5, and remove it with the help of the lateral cleaning effect.

[0062] A piston rod 33 is fixedly connected to one side of the piston plate 36 , and the piston rod 33 is slidably connected to one side of the air box 31 . A driving wheel 34 is fixedly installed at one end of the rotating shaft 8 , and a connecting rod 35 is pinned between the driving wheel 34 and the piston rod 33 .

[0063] In this embodiment, a linkage mechanism is provided between the piston rod 33 and the rotating shaft 8, including a driving wheel 34 and a connecting rod 35. The driving wheel 34 is fixedly installed at one end of the rotating shaft 8, and the connecting rod 35 is pinned on one side of the driving wheel 34. The other end of the connecting rod 35 is pinned to one end of the piston rod 33. When the rotating shaft 8 rotates, the eccentric wheel 10 is driven to rotate, pulling one end of the connecting rod 35. The other end of the connecting rod 35 is pulled by traction to pull the piston rod 33. The piston rod 33 pulls the piston plate 36 to perform piston movement in the air box 31, thereby discharging the gas in the air box 31. It should be noted that a one-way valve is installed in the air outlet pipe 32, and the gas can be discharged through the air box 31 without intake. At the same time, a boost valve is installed in the air nozzle 37 to increase the impact force when the gas is discharged, thereby effectively blowing out the residue in the concave area of ​​the lower mold 5, and cooperating with the lateral cleaning effect to remove it.

[0064] In the present invention, the motor 21 is started to drive the ball screw 18 to rotate. Since the ball screw 18 is connected to the guide block 20, the guide block 20 is slidably arranged in the ground rail 1. Therefore, the guide block 20 drives the moving seat 17 by utilizing the rotation connection structure between the internal thread sleeve 19 and the guide block 20, and the moving seat 17 drives the frame 2 to move on the ground rail 1. After reaching the casting station, the high-strength alloy material is injected into the lower mold 5, and the hydraulic cylinder 24 is started. The telescopic rod end of the hydraulic cylinder 24 is used to drive the upper mold 4 to move downward. After the upper mold 4 and the lower mold 5 are pressed together, the coolant is filled and wrapped outside the mold, so that the metal solution is solidified and formed, and the casting is completed;

[0065] After the casting is completed, the die-casting molded parts are taken away, the electric cylinder 39 is started, and the telescopic rod end of the electric cylinder 39 is used to push the moving assembly, so as to move the cleaning plate 6 to the top of the lower mold 5, so that the brush roller 23 at the bottom of the cleaning plate 6 and the lower mold 5 are arranged in a close relationship, and the electric slide 9 is started to drive the cleaning plate 6 and the brush roller 23 at the bottom of the cleaning plate 6 to move back and forth laterally on the lower mold 5, so as to clean the metal debris or casting residue remaining in the lower mold 5, which not only improves the cleaning effect, but also eliminates the need for operators to clean, thereby eliminating safety hazards;

[0066] The moving assembly includes a slider 13 and a pulley 14 in sequence, wherein the pulley 14 rolls against the upper surface of the ground rail 1, and sliders 13 are symmetrically arranged on both sides of the pulley 14, and the sliders 13 and the slide grooves 16 are clearance-matched, so that a precise moving trajectory is always maintained during the moving process.

[0067] The rotating shaft 8 is started to rotate, and the rotation of the rotating shaft 8 can drive the eccentric wheel 10 on its surface to rotate. Since a push rod 11 with a ball head 12 is provided on one side of the lower mold 5, the ball head 12 is always in contact with the outer ring of the eccentric wheel 10 under the gravity of the entire casting machine base 3, and the casting machine base 3 is pushed to swing back and forth between the two sets of frames 2 by the eccentric distance, thereby increasing the longitudinal action area of ​​the cleaning plate 6 on the lower mold 5, and cooperating with the above-mentioned horizontal reciprocating cleaning, the cleaning area is finally maximized;

[0068] At the same time, when the rotating shaft 8 rotates, it drives the eccentric wheel 10 to rotate, pulling one end of the connecting rod 35. The other end of the connecting rod 35 is pulled by traction to pull the piston rod 33. The piston rod 33 pulls the piston plate 36 to perform piston movement in the air box 31, thereby discharging the gas in the air box 31. A one-way valve is installed in the air outlet pipe 32, and the gas can only be discharged through the air box 31. At the same time, a boost valve is installed in the air nozzle 37 to increase the impact force of the gas when it is discharged, so as to more effectively blow out the residue in the recessed area of ​​the lower mold 5 and remove it in cooperation with the lateral cleaning effect.

[0069] To sum up, in this embodiment, the electric slide 9 is used to drive the cleaning component to move back and forth laterally, and the rotation of the rotating shaft 8 drives the eccentric structure to push the push rod 11, thereby driving the casting machine base 3 and the upper mold 4 and the lower mold 5 to swing. Compared with the cleaning plate 6 and the brush roller 23, the swing of the cleaning plate 6 relative to the lower mold 5 during the cleaning process increases the longitudinal reciprocating movement, thereby expanding the cleaning area and making the cleaning effect more thorough.
