[0022] This utility model provides, for example Figure 1-5 The device shown is an air conditioning component injection mold replacement device, comprising a base 1 and a mold positioning plate 2. The mold positioning plate 2 is installed at the center of the surface of the base 1 and has a mold positioning groove 3. An L-shaped fixed bracket 4 is installed on the base 1. The vertical arm end of the L-shaped fixed bracket 4 is located behind the mold positioning plate 2. A linear slide 5 is installed on the horizontal arm end of the L-shaped fixed bracket 4. A hydraulic cylinder 6 is installed at the bottom of the moving block of the linear slide 5. A lifting plate 7 is installed on the piston rod of the hydraulic cylinder 6. A multi-stage hydraulic cylinder 8 is installed at the bottom of the lifting plate 7. A fixed plate 9 is installed on the telescopic end of the multi-stage hydraulic cylinder 8. Multiple cavity suction cups 10 are installed on the fixed plate 9. Fixed side plates 11 are installed on both sides of the bottom of the lifting plate 7. A clamping cylinder 12 is installed on the fixed side plate 11. The telescopic end of the clamping cylinder 12 passes through the fixed side plate 11. A clamping plate 13 is installed on the telescopic end of the clamping cylinder 12.

[0023] The base 1 is installed on the injection molding machine, and the mold positioning plate 2 is connected to the injection port of the injection molding machine. When the injection mold needs to be replaced, the linear slide 5 starts to work. The moving block on the linear slide 5 drives the hydraulic cylinder 6 and the lifting plate 7 to move. The lifting plate 7 drives the multi-stage hydraulic cylinder 8, the fixed plate 9, and the cavity suction cup 10 to move above the mold positioning plate 2. The multi-stage hydraulic cylinder 8 starts to work. The telescopic end of the multi-stage hydraulic cylinder 8 extends in, driving the fixed plate 9 and the cavity suction cup 10 to descend. The cavity suction cup 10 extends into the mold and passes through the cavity... The suction cup 10 adsorbs the mold, and the extension and retraction of the multi-stage hydraulic cylinder 8 raises the injection mold through the cavity suction cup 10. The clamping cylinder 12 starts working, and the extension end of the clamping cylinder 12 extends to drive the clamping plate 13 to move. The two clamping plates 13 move closer to each other to clamp the mold, improving the clamping and fixing effect, preventing the mold from falling off, and improving safety. The linear slide 5 starts working to drive the mold to move onto the mold cooling plate 23. The hydraulic cylinder 6 starts working, and the extension end of the hydraulic cylinder 6 extends to place the mold onto the mold cooling plate 23. The linear slide 5 and hydraulic cylinder 6 are reset, the lifting plate 7 moves above the mold placement plate 17, the extension end of the hydraulic cylinder 6 extends and drives the lifting plate 7 and the fixed side plate 11 to descend, the clamping plate 13 descends to both sides of the injection mold to be replaced, the clamping cylinder 12 drives the clamping plate 13 to move and clamp and fix the injection mold to be replaced, the extension end of the hydraulic cylinder 6 retracts and drives the injection mold to rise, the linear slide 5 drives the injection mold to be replaced to move above the mold positioning groove 3, the extension end of the hydraulic cylinder 6 extends and causes the injection mold to descend into the mold positioning groove 3, the retraction end of the clamping cylinder 12 retracts the clamping plate 13 to release the injection mold, the injection mold falls into the mold positioning groove 3, which facilitates the replacement of the injection mold, the operation is simple and convenient, improves the mold replacement efficiency, and improves the injection work efficiency. After the suction hole on the cavity suction cup 10 covers the mold, the negative pressure suction closes the valve, forming a local seal, the suction force is concentrated in the contact area, the uncovered hole triggers the valve to close automatically due to air leakage, and avoids overall negative pressure leakage.

[0024] Refer to the instruction manual appendix Figure 2 Included with instruction manual Figure 4 A vacuum pump 14 is installed on the lifting plate 7. The suction end of the vacuum pump 14 is connected to a suction hose 15. One end of the suction hose 15 is connected to the chamber suction cup 10. A solenoid valve 16 is provided on the suction hose 15.

[0025] Vacuum pump 14 starts working, and the air in the cavity suction cup 10 is extracted through the air extraction hose 15 to form a negative pressure to adsorb the mold. The air extraction hose 15 does not affect the hydraulic cylinder 6 to drive the cavity suction cup 10 to rise and fall. After the mold is adsorbed and moved to the required position, the solenoid valve 16 is opened to release the air and eliminate the adsorption force.

[0026] Refer to the instruction manual appendix Figure 2 Included with instruction manual Figure 5 A mold positioning plate 2 is connected to a mold placement plate 17 on one side. The mold placement plate 17 is provided with a transverse slide groove 18. A sliding placement plate 19 is slidably connected in the transverse slide groove 18. A fixed toothed plate 20 is installed on one side of the surface of the sliding placement plate 19. A drive motor 21 is installed on the mold placement plate 17. A gear 22 is installed on the output end of the drive motor 21. The gear 22 meshes with the fixed toothed plate 20.

[0027] The injection mold to be replaced is placed on the mold placement plate 17. When the mold needs to be replaced, the drive motor 21 starts to work. The output end of the drive motor 21 drives the gear 22 to rotate. The gear 22 meshes with the fixed gear plate 20, which moves the fixed gear plate 20. The fixed gear plate 20 moves the sliding placement plate 19 along the transverse slide groove 18. The sliding placement plate 19 moves multiple injection molds to different positions, moving the injection mold to be replaced directly below the lifting plate 7. This eliminates the need for workers to move the injection molds, reducing manual labor intensity and improving work efficiency.

[0028] Refer to the instruction manual appendix Figure 2 On the other side of the mold positioning plate 2, a mold cooling plate 23 is connected. A diagonal support rod 24 is installed at the bottom of the mold placement plate 17 and the mold cooling plate 23. One end of the diagonal support rod 24 is fixedly connected to the base 1.

[0029] The replaced injection mold is placed on the mold cooling plate 23. The mold placement plate 17 and the mold cooling plate 23 are supported and strengthened by the inclined support rod 24 to prevent the mold placement plate 17 and the mold cooling plate 23 from bending, deforming and being damaged, thus improving their service life.

[0030] Refer to the instruction manual appendix Figure 3 Guide slide rods 25 are installed on both sides of the surface of the fixed plate 9. The top of the guide slide rods 25 passes through the lifting plate 7. Anti-slip pads 26 are installed on the clamping plate 13. The cavity suction cup 10 is made of a material that is resistant to high temperature, oil stains and has good elasticity.

[0031] During the lifting process, the fixed plate 9 drives the guide slide 25 to move up and down along the lifting plate 7. The guide slide 25 guides the fixed plate 9. After the cavity suction cup 10 picks up the mold, it causes the fixed plate 9 or the multi-stage hydraulic cylinder 8 to bend and deform, which improves the service life. The cavity suction cup 10 is made of high temperature resistant, oil resistant and elastic material, which can pick up the mold after use and avoid the poor adhesion caused by high temperature and oil.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
