When the electric telescopic rod 6 is started, it will drive the material box 3 to move. When the material box 3 moves, the toggle block 10 installed on the outer surface of the injection tube 8 will move due to the push of the electric telescopic rod 6.

[0025] Furthermore, the bearing 7 is fixedly connected to one side surface of the material box 3, the inner wall of the bearing 7 is movably and rotatably connected to the outer surface of the injection tube 8, the inner wall of the injection tube 8 is connected to the interior of the material box 3 through the feed hole 4, the scraper 11 is installed on the inner wall of the material box 3, one end of the scraper 11 extends from the inner wall of the material box 3 to the interior of the injection tube 8, and the outer surface of the scraper 11 is in movably contact with the inner wall of the injection tube 8. Due to the movement of the electric telescopic rod 6, the toggle block 10 will be inserted into the rotating groove 17 on the side surface of the injection plate 16. When the electric telescopic rod 6 drives the material box 3 to move, the toggle block 10 is completely inserted into the rotating groove 17 to form a fixation between the two.

[0026] Furthermore, the rotating assembly includes a motor 12, a transmission shaft 13 is installed on one side surface of the motor 12, a gear 14 is installed on the outer surface of the transmission shaft 13, a rotating shaft 15 is installed on one side surface of the injection molding shell 1, an injection plate 16 is installed on the inner wall of the rotating shaft 15, a rotating groove 17 is opened on one side surface of the injection plate 16, a latch tooth 18 is installed on the outer surface of the injection plate 16, the motor 12 is installed on one side surface of the injection molding plate, when the gear 14 rotates, it will drive the latch tooth 18 and the injection plate 16 to rotate, when the injection plate 16 rotates, it will rotate on the inner wall of the rotating shaft 15, because at this time the rotating groove 17 and the toggle plate are mutually engaged, so when the injection plate 16 rotates, it will drive the injection tube 8 and the toggle block 10 to rotate.

[0027] Furthermore, one end of the transmission shaft 13 is interconnected with the output end of the motor 12, the outer surface of the injection plate 16 is movably and rotatably connected to the inner wall of the rotating shaft 15, and the latch teeth 18 are installed in a ring array on the outer surface of the injection plate 16.

[0028] Furthermore, the rotating groove 17 is in active contact with a surface of one side of the shifting block 10 , and the latching teeth 18 and the gear 14 are meshed with each other.

[0029] The working principle and use process of the utility model are as follows: when it is necessary to use an anti-clogging injection molding structure, the input port of the plastic machine is connected to the outer surface of the feed hole 4, and when injection is required, the electric telescopic rod 6 is started. When the electric telescopic rod 6 is started, it will drive the material box 3 to move. When the material box 3 moves, the toggle block 10 installed on the outer surface of the injection tube 8 will move due to the push of the electric telescopic rod 6. Because of the movement of the electric telescopic rod 6, the toggle block 10 will be inserted into the rotating groove 17 on the surface of one side of the injection plate 16. When the electric telescopic rod 6 drives the material box 3 to move, the toggle block 10 is completely inserted into the rotating groove 17 to form a fixation between the two.

[0030] When the toggle block 10 is inserted into the rotating groove 17, the motor 12 will rotate. When the motor 12 rotates, it will drive the transmission shaft 13 installed at its output end to rotate. A gear 14 is installed on the outer surface of the transmission shaft 13. The gear 14 and the latch 18 are meshed with each other. Therefore, when the gear 14 rotates, it will drive the latch 18 and the injection plate 16 to rotate. When the injection plate 16 rotates, it will rotate on the inner wall of the rotating shaft 15. Because the rotating groove 17 and the toggle plate are engaged with each other, when the injection plate 16 rotates, it will drive the injection tube 8 and the toggle block 10 to rotate. At this time, due to the drive of the injection plate 16, the injection tube 8 will rotate on the outer surface of the bearing 7. When the injection tube 8 rotates, because the scraper 11 does not rotate with the injection tube 8 at this time, when the injection tube 8 rotates, the stationary scraper 11 will scrape off the injection glue attached to the inner wall of the injection tube 8, so that it will not stick to the injection tube 8, causing the injection tube 8 to be blocked.
