The mold that makes the cross section of a double-chamfered shading ring non-shiny and non-luminous comprises a mold handle, an upper mold base, a lower mold base and a lower pad, wherein the upper mold base is installed at the bottom of the mold handle, and the lower pad is fixedly installed at the top of the lower mold base, the upper mold base corresponds to the lower mold base and the upper mold base is located above the lower mold base, and the top of the upper mold base is fixedly connected with the upper pad. After the mold design and processing of this scheme, the base groove is processed into a double-chamfered structure, and the incident ray and the inclined surface of the hole wall where the incident point is located form a reflected ray that greatly reduces the entry into the lens, thereby improving the camera effect. Although the existing technology cannot completely and effectively eliminate stray light, it can greatly reduce glare and ghosting; the double-sided chamfering in which the front and back chamfering depths are both 50% makes it easier to wrap the substrate, so that the substrate does not reflect light, and the processing operation is simple, which is worthy of promotion.

With the development of science and technology, users also have higher and higher requirements for the quality of electronic products, so in addition to the continuous improvement of the quality of shooting equipment. The shading ring technology used in existing shooting lenses is also required to be higher and higher. On the parallel section with a certain thickness and parallel to the optical axis of the inner hole of the shading ring, after the light source is irradiated to this section, it is easy to form glare and ghosting through the section reflection to the imaging surface, thereby affecting the imaging quality of the shooting lens. The glare and ghosting formed by the shading ring in the traditional shooting lens are serious, resulting in the inability to improve the shooting quality and low reliability, so a mold that makes the double chamfered shading ring section non-shiny and non-luminous is proposed to solve the above problems.

[0027] When in use, the double-layer substrate is placed on the lower pad 4, and the outer punch 9, the inner punch 10 and the outer withdrawal sleeve 12 are driven to punch the substrate through the cooperation of the punching device, and the substrate is made into a double chamfered structure by processing the chamfer. The operation is simple and the processing is convenient. After processing, the chamfer of the substrate is about 20% deep on the front side and about 80% deep on the back side.

[0028] Furthermore, inner guide pillars 11 are interspersed on both sides of the upper pad 5 , the top ends of the two inner guide pillars 11 are fixedly connected to the bottom of the upper die base 2 , and the bottom ends of the two inner guide pillars 11 pass through the upper clamping plate 6 .

[0029] Furthermore, a spring 13 is provided in the mounting groove 7 and on the top of the inner pressure plate 8 .

[0030] Furthermore, the sharp corner of the chamfered bottom of the inner punch 10 is in the shape of an arc spherical surface, which is mirror-processed by a spark rack and the size of the sphere can be adjusted according to demand.

[0031] Furthermore, the width of the chamfered ring wall is between 0.005 mm and 0.012 mm.

[0032] A method for processing a mold that makes the cross section of a double-chamfered shading ring non-bright and non-luminous is invented, comprising the following steps:

[0033] 1) Place the double-layer substrate on the lower pad 4, with the upper clamping plate 6 on the substrate, and initially clamp the substrate by the upper clamping plate 6 and the lower pad 4;

[0034] 2) The die is pressed downward, and the substrate is pressed by the machined inclined surface of the outer withdrawal sleeve 12, the machined chamfer of the inner punch 10, and the arc spherical surface at the bottom thereof, so that the substrate rebounds to form a chamfer. After processing, the substrate is chamfered in a shape with a chamfer depth of 50% on both the front and back sides.

[0035] Through the above arrangement, after the cut surface is chamfered through mold processing, the incident ray and the inclined surface of the hole wall where the incident point is located form a reflected ray that greatly reduces the entry into the lens, thereby improving the camera effect. Although the existing technology cannot completely and effectively eliminate stray light, it can greatly reduce glare and ghosting, and the double-sided chamfering is more convenient for installation, without considering the front and back sides, saving installation time.
