Description

Technical Field

[0001] The utility model relates to the technical field of mold core processing, and more specifically, to a device for processing a cylindrical aspherical mold core. Background Art

[0002] A cylindrical aspherical mold core is a mold used to form an aspherical or cylindrical lens. The design and manufacture of these mold cores are crucial for the quality of optical components, especially in applications that require high precision and specific optical properties.

[0003] For example, the Chinese patent with the publication number CN219521303U discloses a device for processing an aspherical cylindrical mold core, including a mounting block. Symmetrically movable clamping plates are arranged on the mounting block. Arc-shaped elastic sheets are arranged on the clamping plates in a linear array distribution. A plurality of the arc-shaped elastic sheets are on the same vertical plane. The two clamping plates are driven to approach each other so that the plurality of arc-shaped elastic sheets are attached to different regions of the workpiece.

[0004] When fixing the aspherical cylindrical mold core according to the technical solution recorded in this scheme, first place the mold core between the two clamping plates, and then drive the two clamping plates to approach the mold core. At this time, a plurality of arc-shaped elastic sheets on the clamping plates will be attached to the mold core, and different elastic sheets are attached to different regions of the mold core to fix the mold core. Moreover, this kind of fixation is a flexible fixation by movement and will not damage the side wall of the aspherical cylindrical mold core. However, when this scheme is used, the debris generated during the processing of the mold core is likely to enter the mounting block and adhere to the surface of the bidirectional threaded rod, which is likely to cause damage to the bidirectional threaded rod.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a device for processing a cylindrical aspherical mold core is provided, in order to achieve the purpose of having more practical value. Summary of the Utility Model
