[0022] In a further preferred embodiment of the present invention, Figure 1-Figure 5 As shown: the material unloading structure 5 includes a rotating motor 501, a rotating shaft 502, a scraper 503 and a blade 504. The rotating motor 501 is arranged at the top of the material box 4, the rotating motor 501 is provided with a rotating shaft 502 at the bottom end, scrapers 503 are arranged on both sides of the rotating shaft 502, and blades 504 are arranged on the outer side of the bottom end of the rotating shaft 502. There are two groups of scrapers 503, and the two groups of scrapers 503 are symmetrically distributed on the outer side of the rotating shaft 502. There are a plurality of blades 504, and the plurality of blades 504 are arranged at equal intervals on the outer side of the bottom end of the rotating shaft 502.

[0023] Specifically, in this embodiment: when using the injection molding machine 2, the raw material is poured into the interior of the material box 4. After pouring, the rotating motor 501 is started to drive the rotating shaft 502 to rotate. The rotating rotating shaft 502 will drive the scraper 503 to rotate. The rotating scraper 503 will not only stir the raw material to prevent the raw material from agglomerating, but also scrape off the raw material stuck on the inner wall of the material box 4. In addition, by using the rotating blades 504, the raw material can be divided when feeding, preventing uneven feeding, thereby transporting the raw material to the interior of the injection molding machine 2.

[0024] In a further preferred embodiment of the present invention, Figure 1-Figure 5As shown: the auxiliary structure 8 includes a threaded rod 801, a screw sleeve 802, a connecting seat 803, a limiting groove 804, a servo motor 805 and a limiting block 806, the threaded rod 801 is arranged inside one side of the workbench 1, the servo motor 805 is arranged on one side of the threaded rod 801, the screw sleeve 802 is arranged on the outer side of the threaded rod 801, the connecting seat 803 is installed at the bottom end of the driving motor 7, the bottom end of the connecting seat 803 is connected to the top end of the screw sleeve 802, and the limiting groove 804 is connected to the servo motor 805. 04 is opened inside the top of the workbench 1 on both sides of the screw sleeve 802, and a limiting block 806 is arranged inside the limiting groove 804. The top of the limiting block 806 is connected to the bottom end of the connecting seat 803. The outer side of the threaded rod 801 is provided with an external thread, and the inner side of the screw sleeve 802 is provided with an internal thread.

[0025] Specifically, in this embodiment, after the raw material enters the interior of the injection molding machine 2, the drive motor 7 is started to drive the screw 6 to rotate, thereby squeezing the raw material to one side of the interior of the injection molding machine 2, and plasticizing the raw material during the extrusion process. At this time, the use of the heater 9 will heat the raw material again. As the amount of raw material on one side of the interior of the injection molding machine 2 increases, a pressure will be formed to force the screw 6 to retreat, resulting in the melted raw material not being compacted. At this time, the servo motor 805 is started. After starting, the servo motor 805 will drive the threaded rod 801 to rotate. The rotating threaded rod 801 drives the screw 6 on one side of the drive motor 7 at the top of the connecting seat 803 to move to one side through cooperation with the screw sleeve 802, thereby offsetting the pressure inside the injection molding machine 2 that forces the screw 6 to push backward, so that the raw material can be pressed more firmly when it melts on one side of the interior of the injection molding machine 2, and the injection molding effect is better. After compaction is completed, the raw material is injected into the interior of the mold 3 to complete the injection molding work.
