DETAILED DESCRIPTION

[0020] The technical scheme of the present application will be described clearly and completely below in conjunction with the drawings, obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the protection scope of the present application.

[0021] In the description of the utility model, it is necessary to explain, the term "center", "upper", "lower", "left", "right", "vertical", "horizontal", "internal", "external" and so on indicate the orientation or positional relationship is based on the orientation or positional relationship shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and not indicate or imply the device or element indicated must have a particular orientation, with a particular orientation structure and operation, therefore cannot be understood as the limitation of the utility model. In addition, the term "first", "second", "third" is only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0022] In the description of the utility model, it is necessary to explain, unless otherwise explicitly provided and limited, the term "installation", "connection", "connection" should be broad understanding, for example, can be fixed connection, can be detachable connection, or integrally connected, can be mechanical connection, can be electrical connection, can be directly connected, can be indirectly connected through intermediate medium, can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0023] In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as there is no conflict.

[0024] Referring to Figures 1 to 4 A positioning die for frame machining, the frame comprises a first side edge 1, a second side edge 2 and an arc-shaped edge, the first side edge 1 and the second side edge 2 are perpendicular to each other, a top corner 3 is arranged between the first side edge 1 and the second side edge 2, and the arc-shaped edge comprises a first arc-shaped edge 5, a second arc-shaped edge 6 and a third arc-shaped edge 7 arranged in sequence. In addition, a hole needs to be milled on the upper part of the frame by a numerical control machine tool, the lens is placed in the hole during use, and a plurality of mounting holes also need to be formed on the frame.

[0025] The positioning mold of this embodiment includes a main plate 8. The upper part of the main plate 8 has three mounting slots, each corresponding to a workstation. Each workstation mounts a frame blank. The mounting slots have first side grooves 9 and second side grooves 10 corresponding to the first side 1 and second side 2 of the frame, respectively. The mounting slots also have first arc grooves 11, second arc grooves 12, and third arc grooves 13 corresponding to the first arc edge 5, second arc edge 6, and third arc edge 7, respectively. The mounting slots extend to the sides of the main plate 8. During processing, the operator manually places the frame blank into the mounting slot, ensuring each part corresponds to the structure within the slot. After stable placement, a clamping block on one side is used to tighten the frame. A top block 14 is provided on the side of the main plate 8 away from the mounting slots. This is so that when the mold is pushed inward under force, the top block 14 can press against the support block inside the machine tool, reducing the force-bearing area and thus increasing the clamping force, achieving a stable effect.

[0026] To facilitate the removal of the eyeglass frame from the mounting slot after processing, the depth of the mounting slot is less than the thickness of the eyeglass frame, specifically 1-2 millimeters.

[0027] In this embodiment, a rotating frame 15 is also provided on the side of the positioning mold. The rotating frame 15 is in the shape of an open U-shape and is located behind the mold. The middle part of the rotating frame 15 passes through the mold and is rotatably engaged with the mold. The other end of the rotating frame 15 extends out of the mold and then bends back. Then, three pressing blocks 16 are provided on the rotating frame 15 corresponding to the mounting groove. A soft pad (not shown in the figure) is provided at the bottom of the pressing block 16. During use, rotating the rotating frame 15 causes it to flip towards the mold side, so that the bottom of the pressing block 16 abuts against the lens frame blank. Then, rotating the screw achieves the pressing of the clamping block against the lens frame blank. Then, rotating the rotating frame 15 in the opposite direction causes it to disengage from the lens frame blank, which is convenient for the operation of the CNC machine tool. In this embodiment, a hand-held part 4 is also provided on the rotating frame 15. Specifically, the hand-held part 4 is located on the side of the rotating frame 15. The rotating frame 15 and pressing block 16 can press the frame blank into the mounting groove before and during clamping, since stress is generated during clamping. Finally, the hand-held part 4 is used and set on the side of the rotating frame 15 to facilitate the operation of the staff.

[0028] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
