[0022] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a dual-mode synchronous molding device for plastic lenses, including a device body, the device body includes a fixed seat 1, a lower mold 2 is movably installed on the top of the fixed seat 1, an upper mold 3 is movably installed on the top of the lower mold 2, an injection pipe 4 is fixedly installed on the upper mold 3, an opening 7 is opened on the lower mold 2, a positioning column 6 is movably installed inside the opening 7, one end of the positioning column 6 is fixed on the upper mold 3, a positioning hole 10 is opened on the fixed seat 1, and the other end of the positioning column 6 is movably installed inside the positioning hole 10. A rotating seat 8 is rotatably installed inside the lower mold 2, a molding cavity 9 is opened inside the rotating seat 8, and a movable seat 20 is movably installed inside the molding cavity 9. The movable seat 20 is movably installed inside the molding cavity 9. Later, the movement of the movable seat 20 facilitates pushing the molded lens upward.

[0023] In this embodiment, a cavity 14 is opened on the fixed seat 1, a lifting mechanism 15 is fixedly installed inside the cavity 14, a through hole 5 is opened between the cavity 14 and the fixed seat 1, a heating plate 13 is fixedly installed on the top of the fixed seat 1, the heating plates 13 are distributed between the cavities 14, an installation cavity 17 is opened inside the fixed seat 1, a power mechanism 18 is fixedly installed inside the installation cavity 17, an output shaft 16 is installed on the power mechanism 18, and a connection port 19 is opened between the installation cavity 17 and the cavity 14. The power mechanism 18 is a DC motor, and the DC motor drives the rotating seat 8 to rotate 90 degrees through the output shaft 16 to adjust the position of the molding cavity 9.

[0024] In this embodiment, a limiting hole 23 is formed at the bottom of the movable seat 20. The limiting hole 23 is matched with the lifting mechanism 15. A ring seat 21 is fixed on the inner wall of the forming cavity 9. The ring seat 21 is matched with the movable seat 20. A transmission groove 22 is formed at the bottom of the rotating seat 8. A movable block 11 is movably installed inside the positioning hole 10. The movable block 11 is installed inside the positioning hole 10 through a support mechanism 12. A material injection channel is formed inside the upper mold 3. Both ends of the material injection channel are matched with the forming cavity 9. The support mechanism 12 is a support spring. The support spring pushes the positioning column 6 upward. After the positioning column 6 rises, the upper mold 3 and the lower mold 2 are opened for material taking.

[0025] When the device is in use, the lower mold 2 is installed on the top of the fixed seat 1. The opening 7 on the lower mold 2 is aligned with the positioning hole 10. The positioning column 6 on the upper mold 3 is installed inside the positioning hole 10 through the opening 7. The positioning column 6 pushes the movable block 11 downward. Thus, the positioning hole 10 provides left and right limiting forces for the positioning column 6. The lower mold 2 is limited left and right through the positioning column 6.

The material drips into the forming cavity 9 through the material injection ports at both ends of the material injection channel. When the forming cavity 9 is feeding, it is distributed on the top of the heating plate 13. The heating plate 13 is powered on to generate high temperature. The high temperature keeps the material in a fluid state, which is convenient for the subsequent forming of the material. After the feeding is completed, the output shaft 16 of the power mechanism 18 is started to drive the rotating seat 8 to rotate 90 degrees to adjust the position of the forming cavity 9. The forming cavity 9 moves to the top of the cavity 14. An external device fan is started to blow air inward through the through hole 5. The air flow moves upward through the cavity 14 to cool the bottom of the forming cavity 9. The cooled air flow is discharged through the gap between the lower mold 2 and the fixed seat 1. When the lens is formed, the lifting mechanism 15 inside the cavity 14 is started. The lifting mechanism 15 is an electric push rod. One end of the electric push rod is matched with the limiting hole 23 to push the movable seat 20 upward. When the movable seat 20 moves upward, it moves the upper mold 3 upward to open the space at the top, and the lens is taken out and used between the upper mold 3 and the lower mold 2.
