The staff only needs to sequentially place the die-cast dies inside the support frame 10 and then sequentially collect the sprayed dies, thus simplifying the operation process of the staff and improving the spraying efficiency.

[0027] As Figures 1 - 4As shown in the figure, a clamping component is arranged between the feeding components. The clamping component is composed of a through groove 11, a U-shaped slide plate 13, a second servo motor 14, a first rotating plate 15, a first hydraulic cylinder 16, a second rotating plate 17, a lead screw 18, a guide rod 19, a movable block 20, a second hydraulic cylinder 21, a chute 22 and a third servo motor 23. A third servo motor 23 is fixedly installed on the side of the base 1. Symmetrical through grooves 11 are arranged on the top surface of the base 1. Two pairs of pressure sensors 12 are arranged on the top of the base 1. The pressure sensors 12 can send electrical signals to the control panel 3 when the clamping component approaches the feeding component and presses the pressure sensors 12, which is convenient for the control panel 3 to control the clamping component to clamp the mold. The inner walls on the left and right sides of the through groove 11 are respectively fixedly connected to the pressure sensors 12. A chute 22 is arranged inside the base 1. The end of the output shaft of the third servo motor 23 penetrates through the base 1 to the inside of the chute 22. The end of the output shaft of the third servo motor 23 is fixedly provided with a lead screw 18. One end of the lead screw 18 away from the third servo motor 23 is rotatably connected to the inner wall of the chute 22. A movable block 20 is threadedly connected to the outside of the lead screw 18. A guide rod 19 is arranged through the inside of the movable block 20. The guide rod 19 is slidably connected to the movable block 20. The left and right sides of the guide rod 19 are respectively fixedly connected to the inner wall of the chute 22. A second hydraulic cylinder 21 is fixedly installed on the top surface of the movable block 20. The top surface of the output shaft of the second hydraulic cylinder 21 is fixedly provided with a U-shaped slide plate 13. The front and rear sides of the U-shaped slide plate 13 are respectively slidably connected to the base 1 through the through groove 11 and the chute 22. The second servo motor 14 and the first hydraulic cylinder 16 are fixedly installed on the outer sides of the front and rear sides of the U-shaped slide plate 13.

The output shaft of the first hydraulic cylinder 16 penetrates through the U-shaped slide plate 13 and is slidably connected to the U-shaped slide plate 13. The first rotating plate 15 and the second rotating plate 17 are respectively arranged on the inner sides of the front and rear sides of the U-shaped slide plate 13. The end of the output shaft of the second servo motor 14 is fixedly connected to the first rotating plate 15. The end of the output shaft of the first hydraulic cylinder 16 is rotatably connected to the second rotating plate 17. The clamping component can drive the mold to discharge after the mold has completed feeding.

[0028] Specifically, the control panel 3 controls the first hydraulic cylinder 16 to drive the second rotating plate 17 away from the first rotating plate 15 until the distance between the first rotating plate 15 and the second rotating plate 17 reaches the maximum. Then, it controls the second hydraulic cylinder 21 to drive the U-shaped slide plate 13 to move downward to the lowest position. Next, it controls the third servo motor 23 to drive the lead screw 18 to rotate. The rotation of the lead screw 18 drives the movable block 20 to move towards the mold that has completed feeding. The movement of the movable block 20 drives the second hydraulic cylinder 21 and the U-shaped slide plate 13 to move until the U-shaped slide plate 13 contacts and presses the pressure sensor 12. At this time, the mold to be sprayed just moves inside the U-shaped slide plate 13, and the first rotating plate 15 and the second rotating plate 17 are respectively arranged in front of and behind the mold. The pressure sensor 12 sends an electrical signal to the control panel 3. The control panel 3 controls the first hydraulic cylinder 16 to drive the second rotating plate 17 to move forward until the second rotating plate 17 cooperates with the first rotating plate 15 to clamp and fix the mold. The control panel 3 controls the second hydraulic cylinder 21 to drive the U-shaped slide plate 13 to move upward to the highest position, so that the mold is separated from the support frame 10. Then, it controls the third servo motor 23 to drive the movable block 20 to move towards the spraying assembly 4 to realize the spraying of the mold by the spraying assembly 4. Controlling the second servo motor 14 to drive the first rotating plate 15 to rotate can realize the flipping of the mold, so as to spray other surfaces of the mold as needed. After the mold is sprayed, it continues to move in the direction away from the spraying assembly 4 until the U-shaped slide plate 13 contacts and presses another pair of pressure sensors 12. At this time, the sprayed mold just moves directly above the support frame 10 on the top surface of the other set of conveyor belts 5. Then, it controls the second hydraulic cylinder 21 to drive the U-shaped slide plate 13 and the mold to move downward until the mold contacts the inner bottom surface of the support frame 10. Finally, it controls the first hydraulic cylinder 16 to drive the second rotating plate 17 away from the mold, so as to release the clamping and limiting of the mold and realize the discharging of the mold.

[0029] Specific working principle:

[0030] When the device is in use, the spraying component 4 is controlled by the control panel 3 to spray the die-cast mold below. The first servo motor 6 is controlled to drive the toothless gear 7 to rotate. The toothless gear 7 periodically meshes with the transmission gear 8. When the toothless gear 7 meshes with the transmission gear 8, it drives the transmission gear 8 to rotate. The rotation of the transmission gear 8 drives the transmission roller 9 to rotate, and the rotation of the transmission roller 9 drives the support frame 10 to rotate, so that the support frame 10 periodically moves on the top surface of the conveyor belt 5. The first hydraulic cylinder 16 is controlled to drive the second rotating plate 17 away from the first rotating plate 15 until the distance between the first rotating plate 15 and the second rotating plate 17 reaches the maximum. The second hydraulic cylinder 21 is controlled to drive the U-shaped slide plate 13 to move downward to the lowest position. The third servo motor 23 is controlled to drive the lead screw 18 to rotate. The rotation of the lead screw 18 drives the movable block 20 to move towards the mold that has completed feeding. The movement of the movable block 20 drives the second hydraulic cylinder 21 and the U-shaped slide plate 13 to move until the U-shaped slide plate 13 contacts and presses the pressure sensor 12. At this time, the mold to be sprayed just moves inside the U-shaped slide plate 13, and the first rotating plate 15 and the second rotating plate 17 are respectively arranged in front of and behind the mold. The pressure sensor 12 sends an electrical signal to the control panel 3. The control panel 3 controls the first hydraulic cylinder 16 to drive the second rotating plate 17 to move forward until the second rotating plate 17 cooperates with the first rotating plate 15 to clamp and fix the mold. The control panel 3 controls the second hydraulic cylinder 21 to drive the U-shaped slide plate 13 to move upward to the highest position, so that the mold is separated from the support frame 10. The third servo motor 23 is controlled to drive the movable block 20 to move towards the spraying component 4 to realize the spraying of the mold by the spraying component 4. The second servo motor 14 is controlled to drive the first rotating plate 15 to rotate, which can realize the flipping of the mold, so as to spray other surfaces of the mold as needed. After the mold is sprayed, it continues to move in the direction away from the spraying component 4 until the U-shaped slide plate 13 contacts and presses another pair of pressure sensors 12. At this time, the sprayed mold just moves directly above the support frame 10 on the top surface of another conveyor belt 5. The second hydraulic cylinder 21 is controlled to drive the U-shaped slide plate 13 and the mold to move downward until the mold contacts the inner bottom surface of the support frame 10. The first hydraulic cylinder 16 is controlled to drive the second rotating plate 17 away from the mold, so as to release the clamping and limiting of the mold and realize the discharging of the mold. The device can realize the automatic feeding and discharging of the mold, with a high degree of automation. The staff only needs to place the die-cast molds in the support frame 10 in sequence, and then collect the sprayed molds in sequence, thus simplifying the operation process of the staff and improving the spraying efficiency.
