[0031] The cleaning assembly 58 includes a rear plate 581, which is fixedly connected to the rear side of the mounting bracket 51. A rectangular hole 582 is formed on the outer side of the rear plate 581. A rotating rod 583 is rotatably connected to the inner side of the rectangular hole 582. A mounting plate 584 is fixedly connected to the outer side of the rotating rod 583. A fixing cylinder 589 is fixedly connected to the upper side of the mounting plate 584. Multiple fixing blocks 5812 are fixedly connected to the inner side of the fixing cylinder 589. A swing block 5813 is rotatably connected to the outer side of the fixing block 5812. A swing block 5813 is fixedly connected to the upper side of the swing block 5813. The nozzle 5814 is fixedly connected to the outside of the fixing cylinder 589 by a branch block 5810. The outside of the branch block 5810 is fixedly connected to an annular pipe 5811. A delivery pipe 5815 is fixedly connected between the annular pipe 5811 and the nozzle 5814. A connecting plate 55 is fixedly connected to the outside of the fixing frame 51. An air pump 56 is fixedly connected to the outside of the connecting plate 55. A connecting hose 57 is fixedly connected between the air pump 56 and the annular pipe 5811. There are multiple nozzles 5814. The upper side of the fixing cylinder 589 is open.

[0032] When cleaning the material remaining on the surface of gate 4, the air pump 56 is started. Under the action of connecting hose 57 and annular pipe 5811, the high-speed airflow is distributed to multiple conveying pipes 5815. Multiple nozzles 5814 spray high-speed airflow at the residual material at gate 4, causing the residual material to fall down quickly. Since the fixed cylinder 589 is in contact with the upper mold 3 at this time (the upper mold 3 can be controlled to move up and down to make the upper mold 3 and the fixed cylinder 589 fit together), the cleaned material is blocked and collected, avoiding contamination of the mold.

[0033] Gears 585 are fixedly connected to both ends of the rotating rod 583. An electric push rod 588 is fixedly connected to the rear side of the rear plate 581. A U-shaped plate 587 is fixedly connected to the output end of the electric push rod 588. A toothed plate 586 is fixedly connected to the outer side of the U-shaped plate 587. The fixing frame 51 has a U-shaped structure. The gear 585 meshes with the toothed plate 586. When cleaning is required, the electric push rod 588 is controlled to drive the U-shaped plate 587 to rise and fall. The U-shaped plate 587 drives the toothed plate 586 to move. The toothed plate 586 drives the gear 585 to rotate. The gear 585 drives the rotating rod 583 to rotate. The rotating rod 583 drives the mounting plate 584 to rotate. The mounting plate 584 drives the fixing cylinder 589 to rotate below the upper mold 3, which facilitates subsequent cleaning work.

[0034] Example 2

[0035] Based on Example 1, such as Figure 5 , Figure 6As shown, a rotating block 5822 is fixedly connected to the lower side of the swing block 5813. An inclined plate 5823 is rotatably connected to the outer side of the rotating block 5822. A rotating block 5824 is rotatably connected to the outer side of the inclined plate 5823. A lifting block 5825 is fixedly connected to the lower side of the rotating block 5824. A connecting rod 5821 is fixedly connected to the lower side of the lifting block 5825. The lower end of the connecting rod 5821 passes through the lower side of the mounting plate 584 and is fixedly connected to a stop plate 5826. A spring 5820 is fixedly connected between the stop plate 5826 and the mounting plate 584. Two base blocks 5816 are fixedly connected to the lower side of the mounting plate 584. A control rod 5818 is rotatably connected between the two base blocks 5816. A cam 5 is fixedly connected to the outer side of the control rod 5818. 819, cam 5819 abuts against the back plate 5826. The outer side of the bottom block 5816 is fixedly connected to a motor 5817 that drives the control rod 5818 to rotate. When cleaning, the motor 5817 is started. The motor 5817 drives the control rod 5818 to drive the cam 5819 to rotate. The cam 5819 drives the back plate 5826 to move up and down repeatedly. The back plate 5826 drives the connecting rod 5821 to move up and down repeatedly. The connecting rod 5821 drives the lifting block 5825 to move up and down repeatedly. The lifting block 5825 drives the inclined plate 5823 to swing. The inclined plate 5823 drives the swing block 5813 to swing. The swing block 5813 drives the nozzle 5814 to swing repeatedly, which increases the range of the high-speed airflow sprayed by the nozzle 5814 and increases the cleaning effect.

[0036] Working principle: During use, the operator first completes the injection molding through the upper mold 3 and lower mold 2. When demolding is required, the hydraulic cylinder 54 is controlled to drive the upper mold 3 to rise, completing the demolding. The electric push rod 588 is controlled to drive the U-shaped plate 587 to rise and fall. Under the action of the toothed plate 586, gear 585, and rotating rod 583, the mounting plate 584 is rotated. The mounting plate 584 drives the fixed cylinder 589 to be located under the upper mold 3. At this time, the air pump 56 is started. Under the action of the connecting hose 57, annular pipe 5811, and conveying pipe 5815, multiple nozzles 5814 spray high-speed airflow at the gate 4, which facilitates the cleaning and removal of residual materials and blocks and collects the materials. At the same time, the motor 5817 is started to control the cam 5819 to rotate. Under the action of the abutment plate 5826, connecting rod 5821, and inclined plate 5823, the nozzles 5814 on the swing block 5813 swing, increasing the cleaning effect.
