Description

Technical Field

[0001] The utility model relates to the technical field of core fixing jigs, in particular to a core fixing jig for machining a non-spherical cylindrical mold core. Background Art

[0002] At present, the production of aspheric lenses usually adopts die casting. In order to form an aspheric lens, the end face of the mold core must also be processed into an aspheric surface. During the mold core processing, the mold core is generally placed on a centering fixture, and then the mold core is surface processed.

[0003] For example, a Chinese patent with publication number CN210909707U discloses a centering jig for processing aspheric mold cores, including: a base, a positioning seat and two screws. The base and the positioning seat are both cylindrical in shape. The center of the positioning seat has a centering hole, which passes through the positioning seat from top to bottom. The centering hole is directly opposite to the center of the base, and the base and the positioning seat are locked by two screws. The centering jig with the above structure can not only accurately position the aspheric mold core during the mold core processing process to ensure that the mold core is located in the center of the jig, but also save manpower and greatly improve efficiency.

[0004] The technical solution recorded in the proposal uses screws to fix the locating seat and the base to fix the aspheric mold core. As a result, when processing the aspheric mold core, it is necessary to turn the screws to install and disassemble the locating seat each time, and special tools are required to disassemble the screws. As a result, during the processing of the aspheric mold core, the disassembly of the locating seat requires a lot of time, which in turn affects the overall production progress of the enterprise.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a jig for processing aspherical cylindrical mold core centering is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0015] The beneficial effect of adopting the above-mentioned further scheme is that by providing a triangular intersecting connecting rod on the equilateral triangular turntable and hingedly connecting its other end to one side of the upper end of the slider, when the equilateral triangular turntable rotates, the connecting rod can be used to pull the slider for relative movement, thereby pushing the aspheric mold core placed between the fixed core blocks to the center of the base, thereby playing a core-fixing role and making it convenient for users to process the aspheric mold core.

[0016] Furthermore, the base is made of metal, and the surface of the base is coated with an anti-rust coating.

[0017] The beneficial effect of adopting the above further solution is that by setting the base to be made of metal material and coating it with an anti-rust coating, the corrosion resistance and strength of the base can be improved.

[0018] Furthermore, a protective pad is bonded to the inner side of the stator block, and the protective pad is made of silicone material.

[0019] The beneficial effect of adopting the above further scheme is that by bonding a protective pad made of silicone material to the inner side of the fixed core block, firstly, damage to the aspheric mold core can be avoided when clamping the aspheric mold core, and secondly, the heat generated during the processing of the aspheric mold core will not affect the protective pad made of silicone material, thereby increasing its service life.
