On the other hand, since the material of the guard ring is the same as the transparent material of the lens body, when the light beam passes through it, it will cause light noise interference to the lens itself, which forms the so-called "ghost" phenomenon

Embodiment Construction

[0031] The molding mechanism and products of the high-precision optical lens of the present invention will be further described in detail in conjunction with the accompanying drawings.

[0032] Such as figure 2 Shown is a schematic cross-sectional view of a high-precision optical lens forming mechanism 2 of the present invention. The molding mechanism 2 includes a first split mold 20 and a second split mold 28 matched therewith. After the first split mold 20 and the second split mold 28 are molded together, a mold cavity 25 for molding an optical lens 26 can be formed. Wherein the first parting mold 20 can be preset as the movable parting mold 20, and the second parting mold 28 can be preset as the fixed parting mold 28, and the movable parting mold 20 can be separated from the fixed parting mold 28 when the mold is opened.

[0033] The most important feature of the present invention that is different from the prior art is that: during demoulding, the first parting mold 20 a...

Abstract

The present invention relates to one kind of high precision optical lens product and its forming mechanism. The formation mechanism disease the first mold and the second mold, which may be closed to form mold cavity or separated for the lens pushing-out unit to push out the lens from the mold. The mold the lens is attached to includes one lens mold core and one protecting ring mold core fixed integrally, and lens pushing-out unit set on the protecting ring mold core includes pins and corresponding pin holes or one ring slot and corresponding pushing out ring. The lens of the present invention includes lens body and the protecting ring extending from the lens body, and the protecting ring is formed in the protecting ring mold core with fogged surface and thus has opaque.

Description

technical field [0001] The present invention relates to a high-precision optical lens forming mechanism and its products, in particular to an optical lens capable of ensuring high precision and combining several optical lenses made by similar processes It also has a high-precision optical lens forming mechanism and a high-precision optical lens made by this forming mechanism. Background technique [0002] The use of injection molding technology to produce optical lenses is one of the main reasons why many optical equipment or consumer products have been able to reduce production costs and popularize in recent years. The key is to avoid the high cost factor of traditional glass grinding lenses. However, for lenses made of plastic through injection molding, due to the difficulty in controlling the size and deformation during the molding process, it has not been widely used in the field of high-precision optical lenses for a long time, especially for multiple When the lenses a...
