A rotating rod 18 is rotatably connected to the inner wall of the injection cylinder 13. A conveying screw 19 is sleeved on the outer surface of the rotating rod 18. The rotation of the rotating rod 18 can drive the conveying screw 19 to rotate. A control shell 5 is fixedly installed on the top of the injection cylinder 13. A rotating rod 10 is rotatably connected to the inner wall of the control shell 5. Multiple quantitative feeding rods 8 are fixedly connected to the outer surface of the rotating rod 10. The rotation of the rotating rod 10 facilitates the rotation of the quantitative feeding rods 8, which is very convenient. Two semi-circular guard plates 9 are fixedly connected to the inner wall of the control shell 5. One end of the multiple quantitative feeding rods 8 is slidably connected to the inner wall of the two semi-circular guard plates 9. A drive assembly is provided on one side of the surface of the control shell 5.

[0022] A feeding hopper 6 is fixedly installed on the top of the control housing 5. A feeding port 7 is provided on the top of the feeding hopper 6, which facilitates the feeding of materials into the feeding hopper 6. A heating component 12 is provided on the outer surface of the injection cylinder 13. An injection head 3 is fixedly connected to one side of the surface of the injection cylinder 13. An injection port 2 is provided on the surface of the injection head 3, which facilitates the extrusion of materials through the injection port 2. A second motor 17 is fixedly connected to the outer surface of the injection cylinder 13. The output end of the second motor 17 passes through the injection cylinder 13 and is fixedly connected to one end of the rotating rod 18. The second motor 17 can drive the rotating rod 18 to rotate, making the operation more convenient. Both the inner top and inner bottom of the control housing 5 have openings 11, which are connected to the feeding hopper 6 and the injection cylinder 13 respectively. Two support columns 1 are symmetrically fixedly connected to the bottom of the injection cylinder 13, which facilitates the support of the injection molding machine and ensures greater stability during use.

[0023] like Figure 4As shown, the heating assembly 12 includes a heating layer 121, a heating wire is provided on the inner side of the heating layer 121, an insulation layer 122 is provided on the outer wall of the heating layer 121, and a protective layer 123 is provided on the outer wall of the insulation layer 122, which can continuously heat the material inside the injection molding cylinder 13.

[0024] like Figure 2 As shown, the drive assembly includes a first gear 14, which is rotatably connected to the surface of the control housing 5. One end of the rotating rod 10 extends through to the outside of the control housing 5 and is fixedly connected to the first gear 14. A second gear 15 is rotatably connected to the surface of the control housing 5 near the first gear 14. The second gear 15 meshes with the first gear 14, and the rotation of the second gear 15 facilitates the meshing and rotation of the first gear 14, making it more convenient to use. A connecting frame 4 is fixedly connected to the surface of the control housing 5 near the second gear 15. A first motor 16 is fixedly connected to the surface of the connecting frame 4. The output end of the first motor 16 passes through the connecting frame 4 and is fixedly connected to the surface of the second gear 15. The first motor 16 can drive the second gear 15 to rotate, making it more convenient to use.

[0025] In use, this invention first adds material into the hopper 6 through the feeding port 7. During quantitative feeding, the first motor 16 is turned on, driving the second gear 15 to rotate. After the second gear 15 rotates, it meshes with the first gear 14 to rotate, causing the rotating rod 10 to rotate and driving the quantitative feeding rod 8 to rotate. This avoids the situation where excessive material feeding can easily cause blockage in the hopper, ensuring the quality requirements are met during extrusion. With the cooperation of the through-hole 11, the material can be quantitatively fed into the injection cylinder 13. The heating wire inside the heating layer 121 heats the material to prevent the raw material from cooling and solidifying, which would affect subsequent processing. The second motor 17 is turned on, driving the rotating rod 18 to rotate the conveying screw 19, causing the raw material to be conveyed forward. It is then extruded by the action of the injection head 3 and the injection port 2, making it more practical.
