[0022] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments:

[0023] refer to Figure 1-5 A stable co-extrusion die includes a base plate 1, a second support plate 4 fixedly connected to the upper end face of the base plate 1, a first feed pipe 9 fixedly connected inside the second support plate 4, a second feed pipe 12 fixedly connected inside the second support plate 4, a connecting pipe 10 fixedly connected to the left end of both the first feed pipe 9 and the second feed pipe 12, a mold clamping box 11 fixedly connected to the upper end face of the base plate 1, a rotating plate 15 rotatably connected inside the mold clamping box 11, a hydraulic rod 14 rotatably connected to the inner wall of the mold clamping box 11, the telescopic end of the hydraulic rod 14 rotatably connected to the upper end face of the rotating plate 15, and a first support plate 2 fixedly connected to the upper end face of the base plate 1.

[0024] By setting up a hydraulic rod 14, the hydraulic rod 14 can drive the rotating plate 15 to rotate, and the rotation of the rotating plate 15 can adjust the thickness of the extrusion die.

[0025] Furthermore, a first feed hopper 5 is fixedly connected to the surface of the first feed pipe 9, and the bottom end of the first feed hopper 5 is connected to the inside of the first feed pipe 9.

[0026] By setting up the first feed hopper 5, workers can add raw materials into the first feed pipe 9 through the first feed hopper 5.

[0027] Furthermore, a second feed hopper 6 is fixedly connected to the surface of the second feed pipe 12, and the bottom end of the second feed hopper 6 is connected to the inside of the second feed pipe 12.

[0028] By setting up a second feed hopper 6, workers can add raw materials into the second feed pipe 12 through the second feed hopper 6.

[0029] Furthermore, two servo motors 3 are fixedly connected to the left side of the first support plate 2. The output ends of the two servo motors 3 are respectively fixedly connected to the inner walls of the first feed pipe 9 and the second feed pipe 12 with spiral blades 13. The sides of the two spiral blades 13 are respectively rotatably connected to and in contact with the inner walls of the first feed pipe 9 and the second feed pipe 12.

[0030] By setting up servo motor 3, servo motor 3 can drive the spiral blade 13 to rotate.

[0034] The working principle of this utility model is as follows: First, the operator can add raw materials into the first feed pipe 9 and the second feed pipe 12 through the first feed hopper 5 and the second feed hopper 6 respectively. Then, the operator starts the servo motor 3 to drive the spiral blade 13 to rotate clockwise. The spiral blade 13 can drive the raw materials to move to the right. At the same time, the operator starts the heating sleeve 8 to heat and melt the raw materials in the first feed pipe 9 and the second feed pipe 12. The spiral blade 13 can then squeeze the melted raw materials into the mold box 11 through the connecting pipe 10. After the two different raw materials come into contact in the mold box 11, they can be squeezed out together through the gap between the rotating plate 15 and the mold box 11. During operation, the operator can also adjust the gap between the rotating plate 15 and the mold box 11 through the hydraulic rod 14 to adjust the thickness of the extruded material.
