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 assembly 5 includes a driving plate 53, which 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 reciprocate. 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.

[0020] When in use, the die-casting machine 1 is first started through the control 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 opened die-casting mold 2. The lifting plate 35 on the mounting plate 31 rises to the maximum height, and the cleaning head 45 under the connecting rod 41 is lifted to the top of the die-casting machine 1. After the die-casting machine 1 is started, the control console 15 will first control the lifting plate 35 of the adjustment component 3 to descend to the lowest height through the PLC program. During this process, the lifting plate 35 will drive the connecting rod 41 to descend together when it descends, so that the cleaning head 45 under the connecting rod 41 is placed on the opened die-casting mold 2. The cleaning head 45 sprays the cleaning agent to clean the inside of the opened die-casting mold 2. At the same time, the driving assembly 5 drives the connecting rod 41 on the lifting plate 35 to reciprocate through the driving plate 53, so that the cleaning head 45 swings back and forth while spraying the cleaning agent, and flushes 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. 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, and the cleaning head 45 is moved to the upper and lower parts of the die-casting mold 2. 45 is lifted from between the opened die-casting molds 2, and then the die-casting machine 1 closes the cleaned die-casting mold 2 and starts die-casting the workpiece. After the workpiece is produced, the die-casting machine 1 opens the closed die-casting mold 2 again and takes the produced workpiece out of the die-casting mold 2. After taking out the workpiece, the lifting plate 35 is lowered to the lowest height again, so that the cleaning head 45 comes between the opened die-casting molds 2 again, and the die-casting mold 2 is flushed by the cooperation of the driving component 5. After the die-casting mold 2 is cleaned, the driving component 5 stops driving the cleaning connecting rod 41 to rotate, and the cleaning head 45 stops spraying the cleaning agent. , then the lifting plate 35 rises to the maximum height again, and the cleaning head 45 is lifted out of the opened die-casting mold 2. Then the die-casting machine 1 closes the opened die-casting mold 2 again and starts the production of the next workpiece. This cycle is repeated until all workpieces in this batch are produced. 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, so that the cleaning component 4 can be suitable for different die-casting molds 2.

[0021] The difference from the above embodiment is that the upper end of the connecting rod 41 is rotatably connected to the lifting plate 35, the upper end of the connecting rod 41 is coaxially connected with the reversing gear 42, 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, and when the connecting rod 41 rotates, it can drive the cleaning head 45 to rotate synchronously, and a hose 43 is fixedly installed in the hollow part of the connecting rod 41, the upper end of the hose 43 extends from the top of the connecting rod 41, and a connector 44 is fixedly connected to the extended end of the hose 43.

[0022] When the device is used, the connector 44 is connected to the device for delivering the cleaning agent. When cleaning the die-casting mold 2, the device for delivering the cleaning agent delivers the cleaning agent into the cleaning head 45 through the hose 43. At the same time, the drive 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 delivering the cleaning agent stops delivering the cleaning agent, and the drive plate 53 stops driving the reversing gear 42.

[0023] The difference from the above embodiment is that a pipeline is provided inside the cleaning head 45, and the upper end of the pipeline is connected to the lower end of the hose 43. A plurality of horizontal nozzles 46 are fixedly connected to both sides of the cleaning head 45. The plurality of horizontal nozzles 46 are evenly arranged in the middle of the cleaning head 45. The horizontal nozzles 46 remain parallel to the horizontal plane in the horizontal direction. The upper and lower parts of both sides of the cleaning head 45 are fixedly connected with inclined nozzles 47. The inclined nozzles 47 on the upper and lower parts of the cleaning head 45 are inclined upward and downward respectively, and the horizontal nozzles 46 and the inclined nozzles 47 are both connected to the pipeline inside the cleaning head 45.

[0024] Among them, when cleaning the die-casting mold 2, the hose 43 transports the cleaning agent to the pipe in the cleaning head 45, and then sprays it out from each horizontal nozzle 46 and the inclined nozzle 47 through the pipe. Through the cooperation of the horizontal nozzle 46 and the inclined nozzle 47, a vertical fan-shaped cleaning surface will be formed on both sides 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 sweep back and forth over the die-casting mold 2 for flushing.

[0025] The difference from the above embodiment is that the driving assembly 5 also includes a driving box 51, which is fixedly mounted on the lifting plate 35, one side of the driving box 51 is open, the top of the connecting rod 41 passes through the top of the driving box 51, and a sliding groove 52 is provided on the side wall inside the driving box 51.

A driving rack 54 is fixedly connected to the inner wall of one side of the driving groove 531, and the driving rack 54 is meshed with the reversing gear 42.

[0026] When the die-casting mold 2 is cleaned, the driving plate 53 slides back and forth in the sliding groove 52, and the sliding driving plate 53 drives the reversing gear 42 to reciprocate through the driving rack 54. In this process, initially, the driving plate 53 is located at the innermost part of the driving box 51, away from the opening side of the driving box 51. At this time, the horizontal nozzle 46 and the cleaning nozzle on the cleaning head 45 facing the movable mold 21 will face the side of the movable mold 21 away from the console 15, while the horizontal nozzle 46 and the cleaning nozzle on the cleaning head 45 facing the static mold 22 will face the side of the static mold 22 close to the console 15. The driving plate 53 will first move toward the opening side of the driving box 51, and the reversing gear 42 will rotate forwardly under the drive of the driving rack 54, and drive the cleaning head 45 to rotate in the same direction. When the driving plate 53 arrives at the opening side of the driving box 51, the horizontal nozzle 46 and the cleaning nozzle on the cleaning head 45 facing the movable mold 21 will turn to the side of the movable mold 21 close to the console 15, and the cleaning head The flat nozzle and the cleaning nozzle on the cleaning head 45 facing the static mold 22 will face the side of the static mold 22 away from the console 15, so that the cleaning surface composed of the detergent will completely sweep over the movable mold 21 and the static mold 22, and the inside of the movable mold 21 and the static mold 22 will be fully cleaned. After the driving plate 53 arrives at the opening side of the driving box 51, the driving plate 53 will move in the opposite direction and move toward the original position in the driving box 51. The reversing gear 42 rotates in the opposite 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 nozzle 46 and the cleaning nozzle on the cleaning head 45 facing the movable mold 21 will face the side of the movable mold 21 away from the console 15, and the flat nozzle and the cleaning nozzle on the cleaning head 45 facing the static mold 22 will face the side of the static mold 22 close to the console 15, so that the cleaning surface composed of the detergent will rinse the movable mold 21 and the static mold 22 again from another direction, and this reciprocating process will be repeated until the cleaning work is completed.

[0027] The difference from the above embodiment is that the driving assembly 5 also 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 on the opening side of the driving box 51. The output shaft of the driving motor 55 passes through the lifting plate 35. 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 console 15 through an electrical signal.

[0028] When the die-casting mold 2 is cleaned, 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 connection end of the eccentric wheel 56 and the connecting rod 57 faces the direction of the drive box 51, and the drive plate 53 is pushed into the drive box 51 through the connecting rod 57. When the eccentric wheel 56 starts to rotate, the connecting rod 57 pulls the drive plate 53 toward the opening side of the drive box 51. When the eccentric wheel 56 rotates 180 degrees, the eccentric wheel 56 and the connecting rod 57 are connected. The connecting end faces the opposite direction of the driving box 51. At this time, the driving plate 53 arrives at the opening side of the driving box 51. As the eccentric wheel 56 continues to rotate, the connecting rod 57 begins to push the driving plate 53 into the driving box 51, so that the driving plate 53 starts to return. When the eccentric wheel 56 rotates 180 degrees again, the connecting end of the eccentric wheel 56 and the connecting rod 57 faces the direction of the driving box 51 again. At this time, the driving plate 53 returns to its original position. As the driving motor 55 continues to drive, the driving plate 53 will move back and forth in the driving box 51.

[0029] The difference from the above embodiment is that a fixing frame 11 is fixedly connected to the die-casting machine 1, and the fixing frame 11 is located above the clamping mechanism 7 of the die-casting machine 1. A cleaning groove 12 is provided on the fixing frame 11, and a notch 13 is also provided on the fixing frame 11. The notches 13 are distributed on both sides of the cleaning groove 12. A slide rail 14 is fixedly installed on the fixing frame 11, and the slide rail 14 is distributed between the notch 13 and the cleaning groove 12.

A laser sensor 17 is fixedly installed on the clamping mechanism 7, and the laser sensor 17 is connected to the control console 15 through electrical signals.

[0030] 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, and the sewage generated during the cleaning process will fall into the drainage groove 16 below, and the drainage groove 16 will discharge the sewage out of the die-casting machine 1. When the die-casting machine 1 closes or opens the movable mold 21 and the static mold 22 through the clamping mechanism 7, the laser sensor 17 can detect the distance between the movable mold 21 and the static mold 22, and transmit the data to the control console 15.

[0031] The difference from the above embodiment is that a lifting groove 311 is provided on the mounting plate 31, and the lifting groove 311 corresponds to the cleaning groove 12. A slider 32 is fixedly connected to the bottom of the mounting plate 31, and the slider 32 is slidably installed on the slide rail 14. A straight-moving cylinder 33 is provided at the end of the mounting plate 31 away from the die-casting mold 2. The straight-moving cylinder 33 is fixedly installed on the fixing frame 11, and the output shaft of the straight-moving cylinder 33 is fixedly connected to the side of the mounting plate 31, and the straight-moving cylinder 33 is connected to the control console 15 through electrical signals.

[0032] Among them, after the mold opening mechanism opens the movable mold 21 and the static mold 22, the control console 15 controls the straight-moving cylinder 33 to drive the mounting plate 31 to move on the fixed frame 11 through the PLC program according to the data sent by the laser sensor 17, so that the cleaning head 45 is aligned between the opened movable mold 21 and the static mold 22, so that the cleaning head 45 can accurately clean the die-casting mold 2.

[0033] The difference from the above embodiment is that electric lifting rods 34 are fixedly connected to both sides of the mounting plate 31, 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 from the slot 13, and when the mounting plate 31 moves, the electric lifting rod 34 is driven to move in the slot 13, and the electric lifting rod 34 is connected to the control console 15 through electrical signals.

[0034] When cleaning the die-casting mold 2, the control console 15 controls the electric lifting rod 34 to retract the output end through the PLC program, and lowers the lifting plate 35 to the lowest end. After the cleaning is completed, the electric lifting rod 34 raises the lifting plate 35 to the highest end.

[0035] Embodiment 2: The difference from the above embodiment lies in that the die-casting mold 2 comprises a movable mold 21 and a static mold 22. The movable mold 21 is fixedly mounted on the mold clamping mechanism 7, and the static mold 22 is fixedly mounted on the injection mechanism 8 of the die-casting machine 1. The mold clamping mechanism 7 can drive the movable mold 21 to move on the die-casting machine 1, thereby closing and opening the movable mold 21 and the static mold 22. A plurality of temperature sensors 6 are fixedly mounted on the movable mold 21, and the temperature sensors 6 are connected to the control console 15 via electrical signals.

[0036] Among them, when die-casting a workpiece, the die-casting machine 1, under the control of the die-casting control software, pushes the cleaned dynamic mold 21 to the static mold 22 for clamping through the clamping mechanism 7. After the dynamic mold 21 and the static mold 22 are clamped, the die-casting machine 1 injects the molten metal into the clamped die-casting mold 2 through the static mold 22 through the injection mechanism 8 for die-casting. During the die-casting process, the temperature sensor 6 will transmit the temperature in 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 the data, thereby improving the die-casting quality.

[0037] The difference from the above-mentioned embodiment lies in that a die-casting method for molding a cylinder head cover uses a one-step die-casting molding device.

[0038] Working principle: When in use, the die-casting machine 1 is first started through the control 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 opened die-casting mold 2. The lifting plate 35 on the mounting plate 31 rises to the maximum height, and the cleaning head 45 under the connecting rod 41 is lifted to the top of the die-casting machine 1. After the die-casting machine 1 is started, the control console 15 will first control the electric lifting rod 34 to retract the output end through the PLC program to lower the lifting plate 35 to the lowest height. During this process, the lifting plate 35 will drive the connecting rod 41 to descend together when it descends, so that the cleaning head 45 under the connecting rod 41 is lowered between the opened die-casting molds 2. At this time, the horizontal nozzle 46 and the cleaning nozzle on the cleaning head 45 facing the movable mold 21 will face the side of the movable mold 21 away from the control console 15, while the horizontal nozzle 4 on the cleaning head 45 facing the static mold 22 will face the cleaning head 46. 6 and the cleaning nozzle will face the side of the static mold 22 close to the console 15. When cleaning begins, the hose 43 transports the cleaning agent to the pipeline in 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 both sides of the cleaning head 45 to clean the die-casting mold 2. At the same time, the driving motor 55 drives the eccentric wheel 56 to rotate through the output shaft, thereby driving the driving plate 53 to slide back and forth in the sliding groove 52, so that the horizontal nozzle 46 and the inclined nozzle 47 on the cleaning head 45 swing to the other side. When the horizontal nozzle 46 and the inclined nozzle 47 swing to the other side, the cleaning head 45 will swing back to flush the inside of the die-casting mold 2 from multiple angles, thereby improving the cleaning effect and allowing the die-casting mold 2 to be cleaned; 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, and lifts the cleaning head 45 from between the opened die-casting molds 2. Then the die-casting machine 1 closes the cleaned die-casting mold 2 and starts die-casting the workpiece. During the die-casting process, the temperature sensor 6 will transmit the temperature in 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 the data, so as to improve the die-casting quality. After producing the workpiece, the die-casting machine 1 opens the closed die-casting mold 2 again, and takes the produced workpiece out of the die-casting mold 2. After taking out the workpiece, the lifting plate 35 drops to the lowest height again, so that the cleaning head 45 comes to the die-casting mold again. Between the opened die-casting molds 2, the opened die-casting mold 2 is flushed through the cooperation of the driving component 5. After the die-casting mold 2 is cleaned, the driving component 5 stops driving the cleaning connecting rod 41 to rotate, and the cleaning head 45 stops spraying the cleaning agent. Then the lifting plate 35 rises to the maximum height again, and the cleaning head 45 is lifted out of the opened die-casting mold 2. Then 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 the production of all workpieces in this batch is 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 spacing 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, so that the cleaning component 4 can be suitable for different molds.
