[0031] Both ends of the lower die 2 are provided with a first transmission assembly, and the first transmission assembly drives the upper die 6 located on the fixed frame 1 to slide vertically up and down, and the upper die 6 cooperates with the lower die 2.

[0032] The top of the upper mold 6 is fixedly connected with a moving plate 5, and both ends of the moving plate 5 are fixedly connected with sliders 12. The moving plate 5 is provided with an injection port.

[0033] The fixing frame 1 is U-shaped, and two symmetrical slide grooves 19 are provided on the fixing frame 1. The slide grooves 19 are arranged vertically, and two sliders 12 are respectively slidably connected in the corresponding slide grooves 19. The sliders 12 limit the upward and downward sliding of the movable plate 5.

[0034] The first transmission assembly includes a first gear 10 and a rack 13. The first shaft 3 and the second shaft 4 rotate and penetrate the fixing frame 1. The ends of the first shaft 3 and the second shaft 4 extending outside the fixing frame 1 are fixedly sleeved with the first gear 10.

[0035] One end of the two sliders 12 extending outside the fixing frame 1 is fixedly connected to a rack 13, and the rack 13 is slidably matched with the fixing frame 1. The rack 13 is meshed with the corresponding first gear 10 respectively.

[0036] Two symmetrical mounting plates 16 are fixedly connected to the bottom of the lower mold 2, and a seesaw 17 is rotatably connected between the two mounting plates 16. A second transmission assembly is provided on the lower mold 2, and the second transmission assembly drives the seesaw 17 to rotate, and the end of the seesaw 17 hits the bottom surface of the lower mold 2 when the seesaw 17 rotates.

[0037] The second transmission assembly includes a protrusion 15. The bottom surface of the lower mold 2 is fixedly connected with two symmetrical connecting plates 23, a connecting shaft 14 is rotatably connected between the two connecting plates 23, and the protrusion 15 is eccentrically fixedly sleeved on the connecting shaft 14. The protrusion 15 is located between the bottom surface of the lower mold 2 and the rocker plate 17.

[0038] One end of the connecting shaft 14 rotates through one of the connecting plates 23, and one end of the connecting shaft 14 extending outside the connecting plate 23 is fixedly sleeved with the fifth gear 7. A fourth gear 21 is fixedly sleeved on the second rotating shaft 4, and the fourth gear 21 and the fifth gear 7 are meshed.

[0039] One end of the seesaw 17 is fixedly connected to two symmetrical springs 18 , and the other ends of the two springs 18 are fixedly connected to the bottom surface of the lower mold 2 . The protrusion 15 is located between the two springs 18 , and one end of the seesaw 17 away from the springs 18 is fixedly connected to an arc-shaped protrusion.

[0040] Working principle:

[0041] When in use, the injection molding material is passed through the injection molding port on the movable plate 5 into the upper mold 6 and the lower mold 2 for injection molding. After the injection molding is completed, cooling is performed.

[0042] When taking out the formed product, the motor 8 is started to drive the second gear 9 to rotate clockwise. The second gear 9 drives the third gear 11 to rotate, so that the second rotating shaft 4, the first gear 10, and the fourth gear 21 rotate.

[0043] The rotation of the second rotating shaft 4 drives the lower mold 2 to rotate, causing the first rotating shaft 3 to rotate.

[0044] The rotation of the first gear 10 drives the corresponding rack 13 to move upward, thereby driving the slider 12 and the movable plate 5 to move upward, so that the upper mold 6 moves upward, and the upper mold 6 is separated from the lower mold 2 for demolding. The molded product will be located in the lower mold 2 and rotate with the lower mold 2.

[0045] The rotation of the fourth gear 21 drives the fifth gear 7 to rotate, causing the connecting shaft 14 to rotate and the protrusion 15 to rotate. The protruding portion of the protrusion 15 gradually pushes the seesaw 17, causing the seesaw 17 to rotate between the two mounting plates 16. The end of the seesaw 17 close to the spring 18 will move away from the bottom surface of the lower mold 2, thereby stretching the spring 18, and the other end of the seesaw 17 will move toward the bottom surface close to the lower mold 2. Then, the arc-shaped protrusion of the seesaw 17 will collide with the bottom surface of the lower mold 2. As the protrusion 15 rotates, the protruding portion of the protrusion 15 will turn away from the seesaw 17, and under the action of the elastic force of the spring 18, it will pull one end of the seesaw 17, causing the arc-shaped protrusion of the seesaw 17 to leave the lower mold 2. Then, as the protrusion 15 rotates and under the action of the spring 18, the seesaw 17 will swing back and forth, and the arc-shaped protrusion will continuously hit the lower mold 2.

[0046] When the rotation angle of the lower mold 2 is greater than 90 degrees, the product will fall on the inclined plate 22 under continuous knocking, so as to realize automatic demoulding. Since the automobile license plate frame is a thinner sheet, it is easy to fall when it is continuously knocked.

[0047] The motor 8 is started to drive the second gear 9 to rotate counterclockwise, so that the lower mold 2 rotates, and the bottom surface of the lower mold 2 gradually fits with the top surface of the positioning plate 20. The moving plate 5 also drives the upper mold 6 to move downward, and the arc-shaped protrusion on the rocker plate 17 also continuously hits the lower mold 2. Until the upper mold 6 and the lower mold 2 fit together and complete the mold closing, injection molding can be performed again.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
