[0029] The guide bar 2131 is arranged in a spiral shape, and the side of the guide bar 2131 is arranged to fit the inner wall of the discharge port 33 .

[0030] Specifically, the driving shaft 21 rotates, thereby driving the screw conveying paddle 212 to rotate, so that the raw materials are conveyed to the discharge port 33 under the driving action of the screw conveying paddle 212 .

[0031] The rotation of the rotating shaft 21 drives the annular fixing frame 213 to rotate, thereby driving the guide bar 2131 to rotate relative to the inner wall of the discharge port 33, so that the spiral surface of the guide bar 2131 generates a thrust perpendicular to the spiral surface on the raw material entering the discharge port 33, so that the raw material tends to move toward the shaping mold 32, so that the raw material rotates along the guide bar 2131 relative to the inner wall of the discharge port 33 under the action of the guide bar 2131 to generate centrifugal force, so that the raw material moves into the shaping mold 32 under the action of the centrifugal force. Under the action of the centrifugal force, it is not easy for the raw materials to be squeezed and pushed and blocked in the discharge port 33, effectively avoiding the blockage of the discharge port 33.

[0032] Furthermore, the raw material enters the shaping mold 32 to be shaped and then discharged.

[0033] In the above technology, the driving shaft 21 rotates, thereby driving the spiral conveying paddle 212 to rotate, so that the raw materials are conveyed to the discharge port 33 under the pushing action of the spiral conveying paddle 212, and the rotation of the rotating shaft 21 drives the annular fixing frame 213 to rotate, thereby driving the guide bar 2131 to rotate relative to the inner wall of the discharge port 33, so that the spiral surface of the guide bar 2131 produces a thrust perpendicular to the spiral surface on the raw materials entering the discharge port 33, so that the raw materials have a tendency to move toward the shaping mold 32, so that the raw materials rotate along the guide bar 2131 relative to the inner wall of the discharge port 33 under the action of the guide bar 2131 to generate centrifugal force, so that the raw materials move into the shaping mold 32 under the action of the centrifugal force, and under the action of the centrifugal force, it is not easy for the raw materials to be squeezed and pushed and blocked in the discharge port 33, effectively avoiding the blockage of the discharge port 33.

[0034] As a further embodiment of the present invention, the main body 1 is sleeved on the outside of the injection cylinder 3 , on which an air guide tube 14 is fixedly provided, and the shaping mold 32 is fixedly provided in the air guide tube 14 .

[0035] Specifically, flowing air is introduced between the air guide duct 14 and the shaping mold 32 to exchange heat with the shaping mold 32, thereby cooling the shaping mold 32, so that the raw materials in the shaping mold 32 are quickly cooled and shaped, thereby improving production efficiency.

[0036] As a further embodiment provided by the present invention, the invention further comprises a volute shell 31 fixedly mounted on the injection cylinder 3 , wherein centrifugal blades 211 are arranged in a circular array inside the volute shell 31 , and the centrifugal blades 211 are fixedly mounted on the rotating shaft 21 .

[0037] Specifically, the cooling box 4 is fixedly mounted in the main body 1, on which a semiconductor refrigerator 41 is fixedly mounted, and a cooling column 44 is fixedly mounted at the output end of the semiconductor refrigerator 41. The cooling box 4 also includes a first guide tube 42 and a second guide tube 43 fixedly mounted on the cooling box 4, the first guide tube 42 and the second guide tube 43 being connected to the interior of the volute shell 31 and the interior of the air guide cylinder 14, respectively. The driving shaft 21 rotates, thereby driving the centrifugal blades 211 to rotate. When the centrifugal blades 211 rotate, air is subjected to the centrifugal force and gains kinetic energy. The air diffuses around along the centrifugal blades 211 and is guided by the volute shell 31, causing the air to flow toward the air outlet 311 of the volute shell 31, thereby forming a negative pressure at the center of the centrifugal blades 211. As a result, air is sucked into the volute shell 31 through the air inlet 11 of the volute shell 31 and, under the action of the centrifugal blades 211, enters the cooling box 4 through the first guide tube 42.

[0038] Furthermore, the semiconductor refrigerator 41 is driven to cool the cooling column 44, and the air entering the cooling box 4 exchanges heat with the cooling column 44, thereby cooling the air. The cooled air enters between the air guide tube 14 and the shaping mold 32 through the second guide tube 43, thereby exchanging heat with the shaping mold 32, thereby cooling the shaping mold 32, so that the raw materials in the shaping mold 32 are quickly cooled and shaped, thereby improving production efficiency. No additional driving source is required to drive the centrifugal blades 211 to rotate, which effectively simplifies the structure and saves production costs.

[0039] The semiconductor cooler 41 exchanges heat with the outside world through the heat dissipation fins 411 arranged in an array thereon.

[0040] As a further embodiment provided by the present invention, the invention further comprises a fixing plate 13 fixedly arranged on the body 1 , on which the motor 2 is fixedly mounted, and the output end of the motor 2 is fixedly connected to the rotating shaft 21 .

[0041] Specifically, it also includes a blowing pipe 5 fixedly arranged on the main body 1, the air inlet of which is connected to the inside of the air guide tube 14, and the blowing port corresponds to the motor 2. The raw material is put into the injection molding cylinder 3 through the feed port 12, and the driving motor 2 drives the rotating shaft 21 to rotate, thereby driving the screw conveying paddle 212 to rotate, so that the raw material is conveyed to the discharge port 33 under the pushing action of the screw conveying paddle 212, and the rotating shaft 21 rotates to drive the annular fixing frame 213 to rotate, thereby driving the guide bar 2131 to rotate relative to the inner wall of the discharge port 33, so that the spiral surface of the guide bar 2131 produces a thrust perpendicular to the spiral surface on the raw material entering the discharge port 33, so that the raw material has a tendency to move toward the shaping mold 32, so that the raw material rotates along the guide bar 2131 relative to the inner wall of the discharge port 33 under the action of the guide bar 2131 to generate centrifugal force, so that the raw material moves into the shaping mold 32 under the action of the centrifugal force, and under the action of the centrifugal force, it is not easy for the raw materials to be squeezed and pushed and blocked in the discharge port 33, effectively avoiding the blockage of the discharge port 33.

[0042] Furthermore, the rotating shaft 21 rotates, thereby driving the centrifugal blades 211 to rotate. When the centrifugal blades 211 rotate, the air is subjected to the centrifugal force and obtains kinetic energy, and diffuses to the surroundings along the centrifugal blades 211. After being guided by the volute shell 31, the air flows toward the air outlet 311 of the volute shell 31, thereby forming a negative pressure in the center of the centrifugal blades 211, thereby sucking the air into the volute shell 31 through the air inlet 11 of the volute shell 31, and under the action of the centrifugal blades 211, the air enters the cooling box 4 through the first guide pipe 42.

[0043] Furthermore, the semiconductor refrigerator 41 is driven to cool the cooling column 44, and the air entering the cooling box 4 exchanges heat with the cooling column 44, thereby cooling the air. The cooled air enters between the air guide tube 14 and the shaping mold 32 through the second guide tube 43, thereby exchanging heat with the shaping mold 32, thereby cooling the shaping mold 32, so that the raw materials in the shaping mold 32 are quickly cooled and shaped, thereby improving production efficiency. No additional driving source is required to drive the centrifugal blades 211 to rotate, which effectively simplifies the structure and saves production costs.

[0044] Furthermore, the air in the air guide tube 14 is blown toward the motor 2 through the air blowing pipe 5 , thereby dissipating heat and cooling the motor 2 , effectively extending the service life of the motor 2 .

[0045] Working principle: The raw material is put into the injection molding cylinder 3 through the feed port 12, and the driving motor 2 drives the rotating shaft 21 to rotate, thereby driving the screw conveying paddle 212 to rotate, so that the raw material is conveyed to the discharge port 33 under the driving action of the screw conveying paddle 212, and the rotation of the rotating shaft 21 drives the annular fixing frame 213 to rotate, thereby driving the guide bar 2131 to rotate relative to the inner wall of the discharge port 33, so that the spiral surface of the guide bar 2131 generates a thrust perpendicular to the spiral surface on the raw material entering the discharge port 33, so that the raw material is generated. The material moves toward the shaping mold 32, so that the material rotates along the guide bar 2131 relative to the inner wall of the discharge port 33 under the action of the guide bar 2131 to generate centrifugal force, so that the material moves into the shaping mold 32 under the action of the centrifugal force. Under the action of the centrifugal force, the material is not easily squeezed and pushed to be blocked in the discharge port 33, effectively avoiding the blockage of the discharge port 33. The rotating shaft 21 rotates, thereby driving the centrifugal blades 211 to rotate. When the centrifugal blades 211 rotate, the air is subjected to the centrifugal force to obtain The air is then drawn into the cooling box 4 through the first guide pipe 42 and driven by the centrifugal blades 211 to cool the cooling column 44. The air in the cooling box 4 exchanges heat with the cooling column 44, thereby cooling the air. The cooled air enters between the air duct 14 and the shaping mold 32 through the second air guide pipe 43, thereby exchanging heat with the shaping mold 32, thereby cooling the shaping mold 32, so that the raw materials in the shaping mold 32 are quickly cooled and shaped, thereby improving production efficiency. No additional driving source is required to drive the centrifugal blades 211 to rotate, which effectively simplifies the structure and saves production costs. The air in the air duct 14 is blown to the motor 2 through the blowing pipe 5, thereby dissipating heat and cooling the motor 2, effectively extending the service life of the motor 2.
