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 work shall fall within the protection scope of the present invention.
[0020] Please refer to Figures 1 - 4 , the present invention provides a technical solution: a part-taking device for an injection molding machine, including a mounting plate 1 and an electric control slide rail 2. An electric control cylinder 4 is fixedly installed on the top of the mounting plate 1, and a connecting seat 19 is fixedly installed on the top of the mounting plate 1.

Clamping plates 9 are fixedly installed at the ends of the adjusting slide rods 12 away from the limiting plates 13. Adjusting slide holes 16 are opened inside the bent rods 11. The adjusting slide rods 12 are slidably installed inside the adjusting slide holes 16, and the clamping plates 9 and the limiting plates 13 are respectively located on both sides of the bent rods 11. Electromagnets 7 are fixedly installed on the opposite sides of the bent rods 11. Magnet plates 10 are fixedly installed on the opposite sides of the clamping plates 9. Fixed ear plates 6 are fixedly installed at both ends of the electric control slide rail 2. The electric control slide blocks 3 are slidably installed outside the electric control slide rail 2. Limiting slide bars 18 are fixedly installed on both sides of the inner cavity of the electric control slide block 3. Limiting slide grooves 20 are opened on both sides of the electric control slide rail 2. The cross-sectional specifications of the limiting slide bars 18 are matched with the cross-sectional specifications of the limiting slide grooves 20, and the limiting slide bars 18 are slidably installed inside the limiting slide grooves 20. The magnetic poles on the sides of the electromagnets 7 away from the bent rods 11 are the same as the magnetic poles on the sides of the magnet plates 10 away from the clamping plates 9. Protective pads 8 are fixedly installed on the opposite sides of the clamping plates 9.
[0021] Working principle of the above technical solution: When taking materials, only by the cooperation of the electric control slide rail 2 and the electric control slide seat 3, the electric control cylinder 4 is moved to the required position. Then, the electric control cylinder 4 is started. The output end of the electric control cylinder 4 can push the mounting plate 1 downward, so that the clamping plates 9 are located on both sides of the material. Then, an external power supply supplies power to the electromagnet 7, so that the electromagnet 7 has magnetism. And through the principle of like poles repelling each other, the magnet plate 10 can be pushed to move, so that the two clamping plates 9 approach each other, thereby clamping the material. Through automatic control and precise operation, the rejection rate and production cost can be reduced, the product quality and the competitiveness of the enterprise can be improved. Then, the telescopic end of the electric control cylinder 4 retracts, and the material is carried and moved through the cooperation of the electric control slide rail 2 and the electric control slide seat 3, thus completing the material taking. And it can clamp materials with different widths, improving the use effect of the device. The structure is compact, light in weight, and has high flexibility and high precision.
[0022] In another embodiment, as Figures 1 - 4 shown, a threaded hole cap 5 is threadedly connected to the top of the threaded insertion rod 17, and the bottom of the threaded hole cap 5 is in contact with the top of the mounting plate 1.
[0023] By providing the threaded hole cap 5, the threaded insertion rod 17 and the mounting plate 1 can be fixed, thereby fixing the bent rods 11 at both ends of the bottom of the mounting plate 1, and it is convenient for disassembly, improving the use effect of the device.
[0024] In another embodiment, as Figures 1 - 3 shown, telescopic rods 14 are fixedly installed on the opposite sides of the bent rods 11. A return spring 15 is sleeved on the outer side of the telescopic rod 14. One end of the return spring 15 is fixedly connected to one side of the bent rod 11, and the other end of the return spring 15 is fixedly connected to one side of the limiting plate 13.
[0025] When discharging materials, only stop supplying power to the electromagnet 7, so that the repulsive force between the electromagnet 7 and the magnet plate 10 disappears. And through the provided return spring 15, the clamping plates 9 can be urged to reset, thereby releasing the material and completing the discharging.
[0026] Working principle: When material picking is required, the electric control cylinder 4 is moved to the required position only by the cooperation of the electric control slide rail 2 and the electric control slide seat 3. Then, the electric control cylinder 4 is started. The output end of the electric control cylinder 4 can push the mounting plate 1 downward, so that the clamping plates 9 are located on both sides of the material. Then, an external power supply is used to supply power to the electromagnet 7, so that the electromagnet 7 has magnetism. And through the principle of like poles repelling each other, the magnet plate 10 can be pushed to move, so that the two clamping plates 9 approach each other, thereby clamping the material. Through automatic control and precise operation, the rejection rate and production cost can be reduced, and the product quality and the competitiveness of the enterprise can be improved. Then, the telescopic end of the electric control cylinder 4 is retracted, and the material is carried and moved through the cooperation of the electric control slide rail 2 and the electric control slide seat 3, thus completing the material picking. Moreover, materials with different widths can be clamped, improving the use effect of the device. The structure is compact, the weight is light, and it has high flexibility and high precision. When discharging, only the power supply to the electromagnet 7 needs to be stopped, so that the repulsive force between the electromagnet 7 and the magnet plate 10 disappears. And through the arranged return spring 15, the clamping plate 9 can be urged to reset, thereby releasing the material and completing the discharging.
