[0002] A die-casting machine is a pressure casting machine widely used in industrial manufacturing. During the production process of the die-casting machine, it is necessary to clean the die-casting mold to ensure the die-casting quality.

[0003] When some existing die-casting machines clean the mold during die-casting, they spray water downward through vertical water spray holes and inclined water spray holes arranged above the mold to clean the surface and inner end face of the mold. However, the spraying angle of the existing technology is fixed, and it can only clean the mold within a certain range from top to bottom. When the mold opening length is relatively long, the inclined water spray holes will not be able to spray the inner end of the mold surface, and the water spraying direction of the existing technology is single, and it can only clean the inside of the mold from one direction, resulting in poor cleaning effect of the mold and poor quality of the die-cast products.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Please refer to Figures 1 - 10 , a one-time die-casting forming device, including a die-casting machine 1 and a die-casting mold 2 arranged on the die-casting machine 1. The die-casting mold 2 is used for die-casting workpieces. An adjusting component 3, a cleaning component 4, a driving component 5 and a control console 15 are arranged on the die-casting machine 1. The adjusting component 3 includes a mounting plate 31 and a lifting plate 35. The mounting plate 31 is arranged above the die-casting machine 1, and the lifting plate 35 is installed on the mounting plate 31. The mounting plate 31 can drive the lifting plate 35 to slide horizontally above the die-casting machine 1, and the lifting plate 35 can slide vertically on the mounting plate 31. The cleaning component 4 includes a connecting rod 41 and a cleaning head 45. The connecting rod 41 is rotatably connected to the lifting plate 35, and the lower end of the connecting rod 41 is fixedly connected with the cleaning head 45. The cleaning head 45 is used for cleaning the opened die-casting mold 2. When the lifting plate 35 moves, it can drive the connecting rod 41 and the cleaning head 45 connected to the connecting rod 41 to move synchronously. The driving component 5 includes a driving plate 53. The driving plate 53 is installed on the lifting plate 35. The driving plate 53 can move linearly on the lifting plate 35, and the driving plate 53 cooperates with the connecting rod 41. When the driving plate 53 moves, it can drive the connecting rod 41 to rotate reciprocally. The control console 15 is installed on the side of the die-casting machine 1, and the control console 15 is used to control the die-casting machine 1 to work.

[0031] Among them, during use, first start the die-casting machine 1 through the console 15. At this time, the die-casting mold 2 on the die-casting machine 1 is in an open state, and the mounting plate 31 is located above the open die-casting mold 2. The lifting plate 35 on the mounting plate 31 rises to the maximum height, lifting the cleaning head 45 under the connecting rod 41 above the die-casting machine 1. After the die-casting machine 1 is started, the console 15 will first control the lifting plate 35 of the adjusting component 3 to descend to the lowest height through the PLC program. During this process, when the lifting plate 35 descends, it will drive the connecting rod 41 to descend together, thereby lowering the cleaning head 45 under the connecting rod 41 between the open die-casting molds 2. Subsequently, the cleaning head 45 sprays out the cleaning agent to start cleaning the inside of the open die-casting mold 2. At the same time, the driving component 5 drives the connecting rod 41 on the lifting plate 35 to rotate reciprocally through the driving plate 53, so that the cleaning head 45 swings back and forth while spraying out the cleaning agent, flushing the inside of the die-casting mold 2 from multiple angles, thereby improving the cleaning effect and enabling the die-casting mold 2 to be cleaned thoroughly. After the die-casting mold 2 is cleaned, the cleaning head 45 stops spraying out the cleaning agent, and the driving component 5 stops rotating the connecting rod 41. The console 15 controls the lifting plate 35 to rise to the maximum height again, lifting the cleaning head 45 from between the open die-casting molds 2. Subsequently, the die-casting machine 1 closes the cleaned die-casting mold 2 and starts die-casting workpieces. After producing the workpiece, the die-casting machine 1 opens the closed die-casting mold 2 again and takes out the produced workpiece from the die-casting mold 2. After taking out the workpiece, the lifting plate 35 descends to the lowest height again, so that the cleaning head 45 comes between the open die-casting molds 2 again, and through the cooperation of the driving component 5, flushes the opened die-casting mold 2. After cleaning the die-casting mold 2, the driving component 5 stops driving the connecting rod 41 to rotate, the cleaning head 45 ends spraying out the cleaning agent, and then the lifting plate 35 rises to the maximum height again, lifting the cleaning head 45 out of the open die-casting mold 2. After that, the die-casting machine 1 closes the opened die-casting mold 2 again and starts the production of the next workpiece. This process repeats until all workpieces in this batch are completed. When the die-casting machine 1 replaces die-casting molds 2 of different models, resulting in a change in the opening distance of the die-casting mold 2, the console 15 can drive the mounting plate 31 to move to a suitable position according to the opening distance of the die-casting mold 2, so that the cleaning head 45 can be located in the middle of the open die-casting mold 2 again, enabling the cleaning component 4 to be applicable to different die-casting molds 2.

[0032] The difference from the above embodiment is that the upper end of the connecting rod 41 is rotatably connected to the lifting plate 35. A reversing gear 42 is coaxially connected to the upper end of the connecting rod 41. The lower end of the connecting rod 41 is fixedly connected to the upper end of the cleaning head 45. The middle of the connecting rod 41 is hollow. When the connecting rod 41 rotates, it can drive the cleaning head 45 to rotate synchronously. A hose 43 is fixedly installed in the hollow part of the connecting rod 41. The upper end of the hose 43 extends out from the top of the connecting rod 41. A connector 44 is fixedly connected to the extending end of the hose 43.

[0033] Among them, when using this device, the joint 44 is connected to the device for conveying the cleaning agent. When cleaning the die-casting mold 2, the device for conveying the cleaning agent sends the cleaning agent into the cleaning head 45 through the hose 43. At the same time, the driving plate 53 drives the reversing gear 42 to rotate, thereby driving the connecting rod 41 to rotate. After the cleaning is completed, the device for conveying the cleaning agent stops conveying the cleaning agent, and at the same time, the driving plate 53 stops driving the reversing gear 42.

[0034] The difference from the above embodiment is that a pipeline is provided inside the cleaning head 45. The upper end of the pipeline is communicated with the lower end of the hose 43. A plurality of horizontal spray heads 46 are fixedly connected to both sides of the cleaning head 45. The plurality of horizontal spray heads 46 are evenly arranged in the middle of the cleaning head 45. The horizontal spray heads 46 are parallel to the horizontal plane in the horizontal direction. Inclined spray heads 47 are fixedly connected to the upper and lower parts on both sides of the cleaning head 45. The inclined spray heads 47 on the upper and lower parts of the cleaning head 45 are inclined upward and downward respectively. Both the horizontal spray heads 46 and the inclined spray heads 47 are communicated with the pipeline inside the cleaning head 45.

[0035] Among them, when cleaning the die-casting mold 2, the hose 43 conveys the cleaning agent into the pipeline inside the cleaning head 45, and then sprays out from each of the horizontal spray heads 46 and the inclined spray heads 47 through the pipeline. Through the cooperation of the horizontal spray heads 46 and the inclined spray heads 47, a vertical fan-shaped cleaning surface will be formed on each side of the cleaning head 45 to clean the die-casting mold 2. When the cleaning head 45 swings back and forth, it will drive the cleaning surface to reciprocally sweep across the die-casting mold 2 for rinsing.

[0036] The difference from the above embodiment is that the driving assembly 5 further includes a driving box 51. The driving box 51 is fixedly installed on the lifting plate 35. One side of the driving box 51 is open. The top end of the connecting rod 41 passes through the top of the driving box 51. A sliding groove 52 is formed on the inner side wall of the driving box 51. The driving plate 53 is slidably installed in the sliding groove 52. A driving groove 531 is formed on the driving plate 53. A driving rack 54 is fixedly connected to the inner wall of one side of the driving groove 531. The driving rack 54 meshes with the reversing gear 42.

[0037] Among them, when cleaning the die-casting mold 2, the driving plate 53 reciprocates in the sliding groove 52. The sliding driving plate 53 drives the reversing gear 42 to rotate reciprocally through the driving rack 54. In this process, initially, the driving plate 53 is located at the innermost part of the driving box 51, far from the opening side of the driving box 51. At this time, the horizontal spray nozzles 46 and the cleaning spray nozzles on the cleaning head 45 facing the moving mold 21 will face the side of the moving mold 21 away from the control console 15, while the horizontal spray nozzles 46 and the cleaning spray nozzles on the cleaning head 45 facing the stationary mold 22 will face the side of the stationary mold 22 close to the control console 15. The driving plate 53 will first move towards the opening side of the driving box 51. The reversing gear 42 rotates forward under the drive of the driving rack 54 and drives the cleaning head 45 to rotate in the same direction. When the driving plate 53 reaches the opening side of the driving box 51, the horizontal spray nozzles 46 and the cleaning spray nozzles on the cleaning head 45 facing the moving mold 21 will turn to the side of the moving mold 21 close to the control console 15, while the flat spray nozzles and the cleaning spray nozzles on the cleaning head 45 facing the stationary mold 22 will face the side of the stationary mold 22 away from the control console 15, so that the cleaning surface composed of the cleaning agent completely sweeps over the moving mold 21 and the stationary mold 22, and thoroughly cleans the inside of the moving mold 21 and the stationary mold 22. After the driving plate 53 reaches the opening side of the driving box 51, the driving plate 53 will move in the reverse direction and move back to its original position in the driving box 51. The reversing gear 42 rotates in the reverse direction under the drive of the driving rack 54 and drives the cleaning head 45 to rotate in the same direction. When the driving plate 53 returns to its original position, the horizontal spray nozzles 46 and the cleaning spray nozzles on the cleaning head 45 facing the moving mold 21 will face the side of the moving mold 21 away from the control console 15, while the flat spray nozzles and the cleaning spray nozzles on the cleaning head 45 facing the stationary mold 22 will face the side of the stationary mold 22 close to the control console 15, so that the cleaning surface composed of the cleaning agent rinses the moving mold 21 and the stationary mold 22 again from another direction. This process is repeated until the cleaning work is completed.

[0038] The difference from the above embodiment is that the driving assembly 5 further includes a driving motor 55 and a connecting rod 57. The driving motor 55 is fixedly installed at the bottom of the lifting plate 35. The driving motor 55 is located at the opening side of the driving box 51. The output shaft of the driving motor 55 penetrates through the lifting plate 35, and the output shaft of the driving motor 55 extends to the upper side of the lifting plate 35. An eccentric wheel 56 is fixedly connected to the output shaft of the driving motor 55. One end of the connecting rod 57 is eccentrically arranged on the eccentric wheel 56 and is rotatably connected to the eccentric wheel 56. The other end of the connecting rod 57 is rotatably connected to one end of the driving plate 53. The driving motor 55 is connected to the control console 15 through an electrical signal.

[0039] Among them, when cleaning the die-casting mold 2, the control console 15 starts the drive motor 55 through the PLC program, so that the drive motor 55 drives the eccentric wheel 56 to rotate through the output shaft. Initially, the connecting end of the eccentric wheel 56 towards the drive box 51 drives the drive plate 53 into the drive box 51 through the connecting rod 57. When the eccentric wheel 56 starts to rotate, the connecting rod 57 will pull the drive plate 53 towards the opening side of the drive box 51. When the eccentric wheel 56 rotates 180 degrees, the connecting end of the eccentric wheel 56 towards the drive box 51 is reversed. At this time, the drive plate 53 reaches the opening side of the drive box 51. As the eccentric wheel 56 continues to rotate, the connecting rod 57 starts to push the drive plate 53 into the drive box 51, causing the drive plate 53 to start to return. When the eccentric wheel 56 rotates 180 degrees again, the connecting end of the eccentric wheel 56 towards the drive box 51 is towards the drive box 51 again. At this time, the drive plate 53 returns to its original position. With the continuous drive of the drive motor 55, the drive plate 53 will reciprocate in the drive box 51 like this.

[0040] The difference from the above embodiment is that a fixed frame 11 is fixedly connected to the die-casting machine 1. The fixed frame 11 is located above the die-closing mechanism 7 of the die-casting machine 1. A cleaning groove 12 is provided on the fixed frame 11. A notch 13 is also provided on the fixed frame 11. The notches 13 are distributed on both sides of the cleaning groove 12. A slide rail 14 is fixedly installed on the fixed frame 11. The slide rail 14 is distributed between the notch 13 and the cleaning groove 12. A drain groove 16 is provided on the die-casting machine 1. The drain groove 16 is located below the die-closing mechanism 7. A laser sensor 17 is fixedly installed on the die-closing mechanism 7. The laser sensor 17 is electrically connected to the control console 15.

[0041] Among them, when cleaning the die-casting mold 2, the cleaning head 45 descends into the opened die-casting mold 2 through the cleaning groove 12. The sewage generated during the cleaning process will fall into the lower drain groove 16, and the drain groove 16 discharges the sewage out of the die-casting machine 1. When the die-casting machine 1 closes or opens the moving die 21 and the stationary die 22 through the die-closing mechanism 7, the laser sensor 17 can detect the distance between the moving die 21 and the stationary die 22 and transmit the data to the control console 15.

[0042] The difference from the above embodiment is that a lifting groove 311 is provided on the mounting plate 31. The lifting groove 311 corresponds to the cleaning groove 12. The bottom of the mounting plate 31 is fixedly connected with a slider 32. The slider 32 is slidably installed on the slide rail 14. One end of the mounting plate 31 away from the die-casting mold 2 is provided with a straight-line cylinder 33. The straight-line cylinder 33 is fixedly installed on the fixed frame 11. The output shaft of the straight-line cylinder 33 is fixedly connected to the side of the mounting plate 31. The straight-line cylinder 33 is electrically connected to the control console 15.

[0043] Among them, after the mold opening mechanism opens the moving mold 21 and the stationary mold 22, the control console 15 controls the linear cylinder 33 to drive the mounting plate 31 to move on the fixed frame 11 according to the data sent by the laser sensor 17 through the PLC program, so that the cleaning head 45 is aligned between the opened moving mold 21 and the stationary mold 22, so that the cleaning head 45 can accurately clean the die-casting mold 2.

[0044] The difference from the above embodiment is that both sides of the mounting plate 31 are fixedly connected with electric lifting rods 34. The output end of the electric lifting rod 34 is fixedly connected to the bottom of the lifting plate 35. The lower end of the electric lifting rod 34 extends out of the notch 13. When the mounting plate 31 moves, it drives the electric lifting rod 34 to move in the notch 13. The electric lifting rod 34 is connected to the control console 15 through an electrical signal.

[0045] Among them, when cleaning the die-casting mold 2, the control console 15 controls the electric lifting rod 34 to contract the output end through the PLC program, lowers the lifting plate 35 to the lowest end, and after the cleaning is completed, the electric lifting rod 34 raises the lifting plate 35 to the highest end again.

[0046] Embodiment 2: The difference from the above embodiment is that the die-casting mold 2 includes a moving mold 21 and a stationary mold 22. The moving mold 21 is fixedly installed on the mold clamping mechanism 7, and the stationary mold 22 is fixedly installed on the injection mechanism 8 of the die-casting machine 1. The mold clamping mechanism 7 can drive the moving mold 21 to move on the die-casting machine 1, so as to perform mold clamping and mold opening of the moving mold 21 and the stationary mold 22. A plurality of temperature sensors 6 are fixedly installed on the moving mold 21, and the temperature sensors 6 are connected to the control console 15 through electrical signals.

[0047] Among them, when die-casting a workpiece, under the control of the die-casting control software, the die-casting machine 1 pushes the cleaned moving mold 21 towards the stationary mold 22 through the mold clamping mechanism 7 for mold clamping. After the moving mold 21 and the stationary mold 22 are clamped, the die-casting machine 1 injects molten metal into the clamped die-casting mold 2 through the injection mechanism 8 through the stationary mold 22 for die-casting. During the die-casting process, the temperature sensor 6 will transmit the temperature inside the die-casting mold 2 to the control console 15 in real time. The control console 15 analyzes the data in real time through the die-casting control software and dynamically adjusts the working parameters of the die-casting machine 1 according to this data, so as to improve the die-casting quality.

[0048] The difference from the above embodiment is that a die-casting method for forming a cylinder head cover uses a one-time die-casting forming device.

[0049] Working principle: When in use, first start the die-casting machine 1 through the console 15. At this time, the die-casting mold 2 on the die-casting machine 1 is in an open state, and the mounting plate 31 is located above the open die-casting mold 2. The lifting plate 35 on the mounting plate 31 rises to the maximum height, lifting the cleaning head 45 under the connecting rod 41 above the die-casting machine 1. After the die-casting machine 1 is started, the console 15 will first control the contraction of the output end of the electric lifting rod 34 through the PLC program, causing the lifting plate 35 to descend to the lowest height. During this process, when the lifting plate 35 descends, it will drive the connecting rod 41 to descend together, thereby lowering the cleaning head 45 under the connecting rod 41 between the open die-casting molds 2. At this time, the horizontal nozzles 46 and the cleaning nozzles on the cleaning head 45 facing the moving mold 21 side will face the side of the moving mold 21 away from the console 15, while the horizontal nozzles 46 and the cleaning nozzles on the cleaning head 45 facing the stationary mold 22 side will face the side of the stationary mold 22 close to the console 15. When starting the cleaning, the hose 43 transports the cleaning agent into the pipeline inside the cleaning head 45, and then sprays it out from each horizontal nozzle 46 and the inclined nozzle 47 through the pipeline. Through the cooperation of the horizontal nozzle 46 and the inclined nozzle 47, a vertical fan-shaped cleaning surface will be formed on each side of the cleaning head 45 to clean the die-casting mold 2. At the same time, the drive motor 55 drives the eccentric wheel 56 to rotate through the output shaft, thereby driving the drive plate 53 to reciprocate in the sliding groove 52, causing the horizontal nozzles 46 and the inclined nozzles 47 on the cleaning head 45 to swing to the other side. When the horizontal nozzles 46 and the inclined nozzles 47 swing to the other side, the cleaning head 45 will swing back, flushing the inside of the die-casting mold 2 from multiple angles, thereby improving the cleaning effect and enabling the die-casting mold 2 to be cleaned thoroughly;

[0050] After the die-casting mold 2 is cleaned, the cleaning head 45 stops spraying the cleaning agent, and the driving assembly 5 stops rotating the connecting rod 41. The console 15 controls the lifting plate 35 to rise to the maximum height again, lifts the cleaning head 45 from between the opened die-casting molds 2, and then the die-casting machine 1 closes the cleaned die-casting mold 2 to start die-casting the workpiece. During the die-casting process, the temperature sensor 6 will transmit the temperature inside the die-casting mold 2 to the console 15 in real time. The console 15 analyzes the data in real time through the die-casting control software and dynamically adjusts the working parameters of the die-casting machine 1 according to this data, so as to improve the die-casting quality. After the workpiece is produced, the die-casting machine 1 opens the closed die-casting mold 2 again and takes out the produced workpiece from the die-casting mold 2. After the workpiece is taken out, the lifting plate 35 descends to the lowest height again, so that the cleaning head 45 comes to between the opened die-casting molds 2 again. Through the cooperation of the driving assembly 5, the opened die-casting mold 2 is rinsed. After the die-casting mold 2 is cleaned, the driving assembly 5 stops driving the connecting rod 41 to rotate, and the cleaning head 45 ends spraying the cleaning agent. Then the lifting plate 35 rises to the maximum height again, lifts the cleaning head 45 out of the opened die-casting mold 2. After that, the die-casting machine 1 closes the opened die-casting mold 2 again to start the production of the next workpiece, and so on until all the workpieces in this batch are completed. When the die-casting machine 1 replaces the die-casting mold 2 of different models, resulting in a change in the opening distance of the die-casting mold 2, the console 15 can drive the mounting plate 31 to move to a suitable position according to the opening distance of the die-casting mold 2, so that the cleaning head 45 can be located in the middle of the opened die-casting mold 2 again, making the cleaning assembly 4 applicable to different molds.

The scope of the present invention is defined by the appended claims and their equivalents.
