[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: an off-axis aspherical optical lens processing device, including a base 1, a rotating base 2 rotatably disposed directly above the base 1, a servo motor 5 fixedly mounted at the middle position of the upper surface of the base 1, the output shaft of the servo motor 5 fixedly connected to the middle position of the lower surface of the rotating base 2, eight mold grooves 21 arranged in a circumferential array inside the upper surface of the rotating base 2, a demolding component disposed at the lower end of the rotating base 2, a support frame 3 fixedly mounted on one side of the base 1, and a raw material fixedly mounted on the top side of the support frame 3. The lower end of the box 31 and the raw material box 31 is provided with a feeding pipe 34, which is located above one of the mold slots 21. A hydraulic cylinder 32 is fixedly installed on the other side of the top of the support frame 3. The telescopic end of the hydraulic cylinder 32 is fixedly connected to a movable mold 33, which is located directly above one of the mold slots 21. A control console 4 is fixedly installed on the other side of the base 1. The control console 4 is equipped with a controller that controls the servo motor 5 to rotate 45 degrees at a time. A lifting component for moving the demolding part upward is installed on the upper surface of the base 1 away from the movable mold 33.

[0023] In this embodiment, a rotating base 2 is rotatably mounted directly above the base 1, and eight mold slots 21 are formed inside the upper surface of the rotating base 2. This allows the control console 4 to control the servo motor 5 to rotate 45 degrees at a time, so that the movable mold 33 and the feeding pipe 34 are respectively positioned directly above two of the eight mold slots 21. Simultaneously, a raw material box 31, a feeding pipe 34, a hydraulic cylinder 32, and the movable mold 33 are arranged above the rotating base 2. Raw material is extruded from the feeding pipe 34 into the mold slots 21. After the servo motor 5 rotates 45 degrees... The optical lens is then extruded and formed by the movable mold 33. At the same time, a demolding component is set below the mold groove 21, and a lifting component for moving the demolding component is installed on the upper surface of the base 1 away from the movable mold 33. When the mold groove 21 moves above the lifting component, the demolding component moves upward under the action of the lifting component, so that the optical lens in the mold groove 21 is demolded under the action of the demolding component. The processed lens can be easily taken out, thereby enabling the rotational and uninterrupted processing of aspherical optical lenses, thus improving the working efficiency when processing lenses.

[0024] Specifically, a feed pipe 37 is provided on the rear side of the raw material box 31, and a worm gear reducer 36 is installed on the top of the raw material box 31. The output shaft of the worm gear reducer 36 is fixed with an extrusion propeller 161, and the lower end of the extrusion propeller 161 extends into the discharge pipe 34. A shut-off valve 35 is installed at the lower end of the discharge pipe 34. The raw material box 31 includes, from the outside to the inside, an alumina ceramic fiber outer box 313 for heat insulation, a heating plate 312 for heating, and a support structure. The inner steel box 311 and the feeding pipe 34 include, from the outside to the inside, an alumina ceramic fiber outer tube 342 for heat insulation, an electric heating wire 343 for heating, and a steel inner tube 341 for support. The upper surface of the rotating base 2 is provided with a rotating arrow for indicating the direction of rotation. The worm gear reducer 36, through the extrusion propeller 161 fixed on the output shaft, extrudes the molten glass in the raw material box 31 through the feeding pipe 34, and the molten glass falls into the mold groove 21 after being extruded.

[0025] Specifically, the demolding component includes several movable seats 9 arranged in a circular array below the rotating base 2. Each movable seat 9 corresponds to a mold groove 21. Each mold groove 21 has two sealing grooves 22 inside. A sealing push rod 91 is movably inserted into the sealing groove 22. The bottom of the sealing push rod 91 is fixedly mounted on the upper surface of the movable seat 9. The sealing groove 22 and the mold groove 21 are connected. The movable seat 9 is cross-shaped, and springs 92 are arranged on both sides of the upper surface of the movable seat 9. The upper end of the spring 92 is fixedly connected to the lower surface of the rotating base 2. The lower end of the spring 92 is fixedly connected to the upper surface of the movable seat 9. Several slots 23 are also provided inside the rotating base 2, and the slots 23 are distributed outside the sealing groove 22. A telescopic rod 8 is fixedly inserted inside the slot 23. The telescopic end of the telescopic rod 8 is fixedly connected to the upper surface of the movable seat 9. A power supply box 6 is also fixedly installed on the upper surface of the base 1. An electric telescopic rod 7 is fixedly installed on the upper end of the power supply box 6. The telescopic end of the electric telescopic rod 7 is located directly below one of the movable seats 9. The power supply box 6 and the electric telescopic rod 7 are electrically connected. The power supply box 6 and the electric telescopic rod 7 constitute a lifting component.

[0026] In this embodiment, by setting a demolding component at the lower end of the rotating base 2, during lens processing, the servo motor 5 is first started by controlling the console 4. Under the action of the servo motor 5, the rotating base 2 rotates accordingly. Since the servo motor 5 rotates 45 degrees each time, and there are eight mold slots 21, the movable mold 33 and the feeding pipe 34 correspond to two mold slots 21 respectively. The worm gear reducer 36, through the extrusion propeller 161 fixed on the output shaft, extrudes the molten glass in the raw material box 31 through the feeding pipe 34. After the molten glass is extruded... The material falls into the mold groove 21, and then the base 2 is rotated 45 degrees so that the mold groove 21 containing the raw material is located directly below the movable mold 33. The hydraulic cylinder 32 drives the movable mold 33 to move downward to perform molding. This process is repeated. Then, under the action of the demolding component, the electric telescopic rod 7 is started through the control console 4. The telescopic end of the electric telescopic rod 7 pushes against the bottom of the movable seat 9, driving the movable seat 9 to move upward. At this time, the sealing push rod 91 moves upward, and the upper end of the sealing push rod 91 moves inside the sealing groove 22, pushing out the molded lens from the mold groove 21.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
