[0023] The specific workflow is as follows: When an injection molding device for producing inner plastic parts of an inverter is in operation, plastic particles are placed in a melting part 6, and the melting part 6 heats and melts the plastic particles. At the same time, a control panel 2 is operated to allow the melted particles to enter a concave mold plate 7 through the melting part 6. The control panel 2 is operated to allow the male mold plate 5 to extrude the female mold plate 7 to produce the inner plastic parts. When the injection molding work is completed, the male mold plate 5 and the female mold plate 7 are moved and separated, and the molded inner plastic parts fall off and fall into a collecting part 3 for collection. By feeding plastic particles into the feeding hopper 65, the plastic particles impact downward and drive the rotating mechanism 67 to rotate in the inner cavity of the feeding hopper 65, so as to prevent the plastic particles from being blocked when entering the heating box 61 through the feeding hopper 65.

At the same time, the rotating rod 671 is driven to rotate the four special-shaped rods 672 in the inner cavity of the hopper 65. When the plastic particles pass through the hopper 65 and enter the heating box 61, the special-shaped rods 672 can rotate and stir the plastic particles to avoid the phenomenon of blockage of the plastic particles when passing through the hopper 65. At the same time, the rotating rod 671 can drive the cleaning component 674 to rotate and scrape the inner wall of the hopper 65 to avoid the plastic particles from adhering to the inner wall of the hopper 65. When the heating box 61 is heating, the hot air in the heating box 61 will flow out through the hopper 65. When the hot air continues to pass through, the surface of the plastic particles in the hopper 65 will be softened by the heat and adhere to the inner wall of the hopper 65. When the cleaning rod 6741 is driven to rotate in the hopper 65 by the rotating rod 671, the connecting plate 6745 drives the telescopic rod 6743 to slide in the groove 6742 through the centrifugal force, so that the hook ring 6746 can rotate and scrape the inner wall of the hopper 65, thereby The plastic particles with large adhesion on the wall are scraped off, and a scraper 6747 is arranged on the connecting plate 6745. When the rotating rod 671 drives the connecting plate 6745 to rotate, the scraper 6747 can contact and scrape the inner wall of the feeding hopper 65, so as to scrape off the dust and impurities adhered to the plastic particles attached to the inner wall of the feeding hopper 65. At the same time, the scraper 6747 is made of rubber material, so that compared with the iron material, it can reduce the friction damage to the inner wall of the feeding hopper 65 during rotation and scraping, thereby increasing the service life of the feeding hopper 65; When the male mold plate 5 is separated from the female mold plate 7, the molded inner plastic parts fall off and fall into the collection box 31. The inner plastic parts fall on the buffer mechanism 34 to prevent the workpieces from bumping and causing surface damage when falling. Some inner plastic parts fall on the conveyor belt 36 through the buffer mechanism 34. By manipulating the control panel 2, the roller 35 drives the conveyor belt 36 to rotate, so as to transport the inner plastic parts on the conveyor belt 36, thereby eliminating the need for later sorting work. At the same time, when the device stops the injection molding work, the control panel 2 is used to make the connecting shaft 32 drive the pushing mechanism 33 to move in the collection box 31, push the remaining workpieces onto the conveyor belt 36, and at the same time, the surfaces of the buffer mechanism 34 and the conveyor belt 36 can be cleaned; The workpiece dropped on the triangular plate 344 contacts the surface of the triangular plate 344, and the triangular plate 344 is subjected to the extrusion force and the expansion and contraction of the buffer spring 343 to buffer the dropped workpiece, thereby preventing the workpiece from bumping against the surface of the workpiece when it falls. By setting the triangular plate 344 in a triangular shape, after the triangular plate 344 buffers the dropped workpiece, part of the workpiece can pass through one end of the triangular plate 344 and fall onto the conveyor belt 36 for subsequent conveying work. The push plate 331 is driven to move in the inner cavity of the collection box 31 by the connecting shaft 32, so that the push plate 331 pushes the triangular plate 344 through the rubber strip 332 to push the workpiece on the side of the conveyor belt 36 away from the conveyor belt 36 through the triangular plate 344. At the same time, when the push plate 331 moves, it can drive the arc plate 333 to scratch and clean the inner wall of the collection box 31. At the same time, by setting a rounded plate 334 on the bottom plate 1 of the push plate 331, when the push plate 331 continues to move, when passing through the triangular plate 344, the top of the triangular plate 344 can be cleaned through the corners of the rounded plate 334, so that when the triangular plate 344 contacts the inner plastic part, the waste chips dropped on the inner plastic part can be cleaned.
