[0025] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0026] Reference Figure 1 and Figure 2The present invention is a cleaning device for forging dies, the main structure of which includes a cleaning cylinder 1, a plurality of legs are arranged at the bottom of the cleaning cylinder 1, the top of the cleaning cylinder 1 is open, the forging die 2 is placed into the cleaning cylinder 1 from the top opening, the top of the cleaning cylinder 1 is vertically slidably connected with a shelf plate 3 for placing the forging die 2, the cross-sectional size of the shelf plate 3 is adapted to the cross-sectional size of the cleaning cylinder 1, so that the shelf plate 3 can block the top of the cleaning cylinder 1, and the forging die 2 is inverted on the shelf plate 3. Such a structure will be placed on the shelf plate 3 before cleaning. The plate 3 slides upward to the top, so that the forging die 2 is inverted on the shelf plate 3, and then the shelf plate 3 is slid downward so that the forging die 2 moves downward to the inside of the cleaning cylinder 1, so that the forging die 2 can be cleaned inside the cleaning cylinder 1. The bottom of the forging die 2 is provided with a die cavity 4, and the die cavity 4 is the internal cavity structure of the forging die 2. The forging is pressed into the die cavity 4 by the press so that the forging is forged into the shape of the die cavity 4. When the forging die 2 is placed on the shelf plate 3, the die cavity 4 faces downward, and the shelf plate 3 is provided with a die cavity 4 for use with the die cavity 4. The through hole 5 has a size larger than that of the mold cavity 4, so that the gas or liquid below can enter the mold cavity 4 after passing through the through hole 5, which is convenient for cleaning the inside of the mold cavity 4. The shelf plate 3 is provided with a plurality of pressing blocks 6 used in conjunction with the top of the forging mold 2. The setting of the pressing blocks 6 can press and fix the forging mold 2 on the shelf plate 3 to avoid the forging mold 2 moving relative to the shelf plate 3 during the cleaning process, and can also prevent the gap between the two from causing leakage of the cleaning liquid, thereby improving the accuracy and cleaning effect of cleaning. The cleaning cylinder 1 is fixed with a sealing ring 7 used in conjunction with the bottom of the shelf plate 3 by bonding or bolts. In this structure, when the shelf plate 3 drives the forging mold 2 to slide downward until the shelf plate 3 contacts the sealing ring 7, the internal space of the cleaning cylinder 1 below the shelf plate 3 and the mold cavity 4 form a relatively closed cleaning space. In this relatively closed cleaning space, the mold cavity 4 can be cleaned with compressed air or cleaning liquid, and the debris and impurities generated by the cleaning are retained in the closed space and will not overflow into the external environment, making the cleaning environment tidier and greatly improving the environmental protection of the cleaning; A fixing seat 8 is fixed to the bottom of the cleaning cylinder 1 by welding or bolts, and a rotating ring 9 is provided on the outer side of the fixing seat 8 through a bearing rotating sleeve. The rotating ring 9 rotates along the outer side of the fixing seat 8 under the drive of any power structure. A plurality of stirring rods 10 are distributed in an array fixed by welding or bolts on the rotating ring 9. The rotating ring 9 is used to drive the plurality of stirring rods 10 to rotate at the same time. An air chamber 11 is provided on the fixing seat 8, and the air chamber 11 is arranged inside the fixing seat 8. An air inlet pipe 12 connected to the air chamber 11 and a liquid inlet pipe 13 and a liquid outlet pipe 14 connected to the inside of the cleaning cylinder 1 are provided on the fixing seat 8. External compressed air enters the air chamber 11 through the air inlet pipe 12, and external cleaning liquid enters the cleaning cylinder 1 from the liquid inlet pipe 13, and the cleaning is completed. The cleaning liquid containing impurities and debris is then discharged from the liquid outlet pipe 14. The corresponding positions of the rotating ring 9 and the stirring rod 10 are provided with jet channels 15 which are rotatably connected to the air chamber 11. Such a structure allows the compressed air in the air chamber 11 to continuously pass through the jet channel 15 on the rotating ring 9 and enter the jet channel 15 in the stirring rod 10 during the rotation of the rotating ring 9, thereby maintaining the continuous inflation of the jet channel 15 in the stirring rod 10. The stirring rod 10 is provided with a plurality of jet nozzles 16 which are connected with the jet channel 15. The compressed air entering the jet channel 15 on the stirring rod 10 is ejected from the jet nozzles 16. The jet nozzles 16 are arranged toward the mold cavity 4. After being ejected from the jet nozzles 16, the compressed air passes through the through holes 5 into the mold cavity 4, and then enters the mold cavity 4 through the through holes 5. The auxiliary rotating ring 9 drives the stirring rod 10 to rotate, so that the compressed air can be rotated and sprayed to various positions in the mold cavity 4, so that the debris and impurities on the inner wall of the mold cavity 4 are effectively cleaned up, which greatly improves the cleaning effect of the debris and impurities in the mold cavity 4. The stirring rod 10 is provided with a cover plate 17 for closing the air nozzle 16. The cover plate 17 can close or open the air nozzle 16. When it is opened, the mold cavity 4 is jet-cleaned by compressed air, and the cleaned impurities fall into the closed space. After jet cleaning, the air inlet pipe 12 and the cover plate 17 are closed, and the liquid inlet pipe 13 is opened, so that the cleaning liquid enters the closed space composed of the cleaning cylinder 1 and the mold cavity 4 from the liquid inlet pipe 13, ensuring that the cleaning liquid can be fully filled into the mold cavity 4. After the cleaning liquid is filled, the rotating ring 9 is used to drive multiple stirring rods 10 to rotate, and the filled cleaning liquid is stirred, so that the cleaning liquid can fully flush various positions inside the mold cavity 4. Even if there are multiple recessed or convex positions in the mold cavity 4, the cleaning liquid can effectively flush them, thereby achieving effective cleaning of different types of forging molds 2, and cleaning the forging mold 2 more comprehensively and thoroughly. The cleaned impurities and debris are discharged from the liquid outlet pipe 14 along with the cleaning liquid. The bottom of the preferred cleaning cylinder 1 is a cone with a wide top and a narrow bottom, so that the cleaning liquid is easier to be concentrated and discharged from the liquid outlet pipe 14, reducing the difficulty of subsequent processing of impurities and debris, and greatly improving the convenience of cleaning. After the cleaning liquid is drained, the cover plate 17 can be opened again.The compressed air is blown into the die cavity 4 by the air nozzle 16 to dry it quickly, so that the forging die 2 can be quickly put into the subsequent forging process, which greatly improves the cleaning efficiency.

[0027] Preferably, a plurality of support rods 18 are fixed to the stirring rod 10 by welding or bolts, and the support rod 18 is arranged toward the mold cavity 4. The structure composed of the plurality of support rods 18 and the stirring rod 10 can increase the contact area with the cleaning liquid, so that the structure composed of the two can better stir the cleaning liquid when rotating, thereby improving the flushing and cleaning effect of the cleaning liquid on the inner wall of the mold cavity 4. The air nozzle 16 is arranged on the top of the support rod 18, and the air jet channel 15 extends to the inside of the support rod 18. Such a structure allows compressed air to be accurately blown from the air nozzle 16 at the end of the support rod 18 toward the mold cavity 4, thereby making the position of the air nozzle 16 closer to the mold cavity 4, further improving the cleaning effect of debris and impurities on the inner wall of the mold cavity 4.

[0028] Preferably, a closed box 19 is fixed to the top of the support rod 18 by welding or bolts, and the closed box 19 is fixed to the multiple support rods 18 by welding or bolts at the same time. The multiple air nozzles 16 on the top of the support rods 18 are all located in the closed box 19, and the cover plate 17 is symmetrically connected to the top of the closed box 19 by a pin or a hinge. Such a structure allows the multiple air nozzles 16 to be exposed when the two cover plates 17 on the top of the closed box 19 are opened by rotation, which is convenient for air jet cleaning. After the air jet cleaning is completed, the two cover plates 17 rotate in the opposite direction to seal the multiple air nozzles 16 in the closed box 19, so that when the cleaning liquid enters and fills the cleaning cylinder 1 and the mold cavity 4, it will not enter the air nozzle 16, ensuring the subsequent normal use of the air nozzle 16. The stirring rod 10 is provided with a telescopic rod 20 for controlling the rotation of the cover plate 17, which can be specifically a cylinder or an oil cylinder structure. The cover plates 17 on both sides are pushed open by the telescopic movement of the telescopic rod 20, making the opening and closing control of the cover plates 17 more convenient.

[0029] Preferably, refer to Figure 3 and Figure 5A return spring 21 is provided between the cover plate 17 and the side wall of the closed box 19. Under the action of the return spring 21, the cover plate 17 remains in a closed state. The movable end of the telescopic rod 20 passes through the bottom of the closed box 19 and is slidably connected thereto. The specific position where the movable end passes through the closed box 19 is sealed by a sealing rubber to prevent the cleaning liquid from entering the closed box 19 from the penetration position. The movable end of the telescopic rod 20 is symmetrically connected to rollers 22 through bearings for rotation. The rollers 22 are in rolling contact with the bottom of the cover plate 17. With such a structure, when the telescopic rod 20 is extended, the rollers 22 on both sides of the movable end will be in rolling contact with the bottom of the cover plates 17 on both sides, and the cover plates 17 on both sides will be pushed open while rolling relative to the cover plates 17, so that the opening process of the cover plates 17 on both sides is smoother. The opened cover plate 17 stretches the return spring 21. When it needs to be closed, only the telescopic rod 20 needs to be contracted. Under the action of the return spring 21, the cover plate 17 can be rotated in the opposite direction to close the closed box 19, thereby ensuring the accuracy of the opening and closing control of the cover plate 17 and achieving better closed protection for the air nozzle 16.

[0030] Preferably, refer to Figure 6 and Figure 7 The adjacent sides of the two cover plates 17 are fixed with sealing strips 23 by bonding or bolts, and the two sealing strips 23 are arranged to overlap each other. With this structure, when the two cover plates 17 rotate relative to each other to close the closed box 19, the sealing strips 23 on the sides of the two cover plates 17 overlap and contact each other, thereby achieving double sealing of the contact position of the cover plates 17, further improving the sealing effect of the cover plates 17 on the closed box 19.

[0031] Preferably, refer to Figure 8 and Fig. 9 A plurality of penetrating air holes 24 are provided on the side of the air chamber 11, so that the compressed air in the air chamber 11 can be discharged through the air holes 24, and a partition bar 25 is provided between adjacent air holes 24, and the partition bar 25 is used to separate adjacent air holes 24, and the jet channel 15 is rotatably connected with the air holes 24, and the width of the jet channel 15 is greater than the width of the partition bar 25. Such a structure enables the jet channel 15 to always be connected with the air holes 24 on the side of the air chamber 11 when the rotating ring 9 rotates, and even if the jet channel 15 rotates to the partition bar 25, the jet channel 15 can maintain a connected state with the air holes 24 on both sides because the width of the jet channel 15 is greater than the partition bar 25, thereby realizing continuous air supply to the jet channel 15 and ensuring the continuity of jet cleaning of the inner wall of the mold cavity 4.

[0032] Preferably, a plurality of penetrating guide holes 26 are provided on the side wall of the cleaning cylinder 1, and a plurality of guide blocks 27 are fixed to the side surfaces of the shelf plate 3 by welding or bolts, and the guide blocks 27 are slidably connected in the guide holes 26. Such a structure utilizes the vertical sliding of the plurality of guide blocks 27 in the guide holes 26 to effectively restrict the up and down sliding movement of the shelf plate 3, so that the shelf plate 3 is more stable when sliding up and down, so that when the guide blocks 27 move to the bottom of the guide holes 26, the shelf plate 3 can accurately contact the sealing ring 7 below, so that the sealing structure composed of the mold cavity 4 and the space below the shelf plate 3 in the cleaning cylinder 1 is more rigorous, and it is not easy for the cleaning liquid to flow out, so that the cleaning liquid can smoothly fill the mold cavity 4, thereby improving the accuracy and effectiveness of subsequent cleaning, and a power component for driving the guide block 27 to slide is provided on the cleaning cylinder 1, and the power component is used to drive the guide block 27 to slide up and down, so that the placement of the forging mold 2 and the movement toward the inside of the cleaning cylinder 1 are more convenient and smooth.

[0033] Preferably, the power assembly includes a lifting motor 28, a screw rod 29, and a sliding rod 30. The lifting motor 28 and the sliding rod 30 are symmetrically fixed on both sides of the cleaning barrel 1 by welding or bolts. The screw rod 29 is fixed on the output shaft of the lifting motor 28 by welding or bolts. The screw rod 29 passes through the guide block 27 and is threadedly connected thereto. The sliding rod 30 passes through the guide block 27 and is slidingly connected thereto. Such a structure utilizes the lifting motor 28 to drive the screw rod 29 to rotate, so that the guide block 27 can slide up and down along the sliding rod 30 in the guide hole 26, making the up and down sliding drive of the shelf plate 3 smoother and more stable.

[0034] Preferably, refer to Figure 3 and Figure 4 The shelf plate 3 is fixed with a plurality of guide posts 31 by welding or bolts, and a slider 32 is slidably connected to the guide post 31, and the slider 32 is slidably connected in the guide hole 26. The forging die 2 will not contact the slider 32 when it is buckled on the shelf plate 3. A tension spring 33 is provided between the slider 32 and the shelf plate 3. The pressing block 6 is rotatably connected to the slider 32. Preferably, an avoidance groove is provided in the middle of the slider 32, and the pressing block 6 can enter the avoidance groove after being rotated horizontally. Such a structure is convenient for the forging die. 2 is placed on the shelf 3, the slider 32 is slid upward to stretch the tension spring 33, and when the slider 32 is located obliquely above the forging die 2, the pressing block 6 is rotated horizontally to rotate it to the top of the forging die 2, and then the slider 32 is released, and the slider 32 and the pressing block 6 can automatically slide downward under the elastic force of the tension spring 33 until the pressing block 6 is pressed against the top of the forging die 2, so that the forging die 2 is automatically pressed and fixed. The structure is simple, the operation is convenient, and the pressing operation of the forging die 2 is more convenient and effective.

[0035] Preferably, a rotating motor 34 is fixed to the bottom of the cleaning cylinder 1 by welding or bolts, and mutually meshing gears 35 are fixed to the outer side of the rotating ring 9 and the output shaft of the rotating motor 34 by welding or bolts. Preferably, a notch is provided on the side wall of the bottom of the cleaning cylinder 1, and the gear 35 on the output shaft of the rotating motor 34 meshes with the gear 35 on the outer side of the rotating ring 9 after passing through the notch, thereby realizing continuous rotation drive of the rotating ring 9, making the jet cleaning and liquid flushing cleaning of the mold cavity 4 more efficient.

[0036] Working principle: In the present invention, a shelf plate 3 is vertically slidably arranged at the top of the cleaning cylinder 1, and the forging die 2 is inverted on the shelf plate 3, so that the forging die 2 can move downward under the drive of the shelf plate 3 until the bottom of the shelf plate 3 contacts the sealing ring 7, so that the interior of the cleaning cylinder 1 and the die cavity 4 form a relatively closed space, so that the die cavity 4 is cleaned in this closed space, and the debris and impurities generated during cleaning are effectively confined in the cleaning cylinder 1 and will not overflow into the surrounding environment, thereby ensuring the cleanliness of the cleaning environment; a fixed seat 8 is arranged at the bottom of the cleaning cylinder 1, and a rotating ring 9 is arranged on the outer rotating sleeve of the fixed seat 8, and a plurality of stirring rods 1 are arranged in an array on the rotating ring 9 0, an air chamber 11 is arranged on the fixed seat 8, and corresponding positions of the rotating ring 9 and the stirring rod 10 are provided with an air jet channel 15 connected with the air chamber 11. Such a structure allows compressed air to enter the air chamber 11 through the air inlet pipe 12, pass through the rotating ring 9 and then enter the air jet channel 15 on the stirring rod 10, and be ejected toward the mold cavity 4 from the air jet nozzle 16 on the stirring rod 10. With the continuous rotation of the rotating ring 9, the air jet cleaning of various positions in the mold cavity 4 is realized, and the impurities and debris remaining on the inner wall of the mold cavity 4 are effectively cleaned, and the cleaned impurities and debris remain in the cleaning barrel 1 and will not overflow to the outside, thereby improving the effect and convenience of cleaning the impurities and debris inside the forging mold 2. A cover plate 17 for closing the air nozzle 16 is provided on the stirring rod 10. With this structure, after the impurities and debris on the inner wall of the forging die 2 are removed by compressed air, a cleaning liquid is introduced into the cleaning barrel 1 through the liquid inlet pipe 13 on the fixed seat 8, so that the cleaning liquid fills the closed space composed of the cleaning barrel 1 and the die cavity 4, thereby dissolving the debris and impurities that have been removed into the cleaning liquid, which is convenient for effectively discharging these impurities and debris. At the same time, the air nozzle 16 on the stirring rod 10 is closed by the cover plate 17, and the rotating ring 9 is used to drive the multiple stirring rods 10 to rotate, so as to stir the cleaning liquid filled in the closed space, thereby realizing continuous flushing of the inner wall of the die cavity 4. The cleaning liquid can be filled into any irregular position in the mold cavity 4 for flushing, thereby covering any area that cannot be reached by the jet cleaning. Therefore, the impurities and debris remaining on the inner wall of the mold cavity 4 of any shape can be thoroughly and comprehensively cleaned. After cleaning, the cleaning liquid containing the impurities and debris is discharged from the liquid outlet pipe 14. Since the forging mold 2 is inverted on the shelf 3, the residual amount of cleaning liquid and impurities and debris in the mold cavity 4 is greatly reduced. After that, the cover plate 17 can be opened again, and the compressed air sprayed from the air nozzle 16 can be used to quickly blow dry the mold cavity 4, which greatly improves the efficiency and convenience of cleaning the forging mold 2, and further reduces the impact on the subsequent forging quality.
