AI Technical Summary

Problems solved by technology

At present, the lens eccentricity accuracy guaranteed by the industry is 2μ, which is very difficult for the existing mold structure, and it cannot be realized within 1.5μ (it is only accidental, and cannot be formally mass-produced)

Embodiment Construction

[0021] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

[0022] As shown in the figure, a small-diameter plastic optical lens mold core fitting device includes a front template 1 and a rear template 2, a front template hole 11 is provided on the front template 1, and a rear template hole is provided on the rear template 2 twenty one. A front mold core 4 is arranged in the front template hole 11 , and a rear mold core 5 is arranged in the rear template hole 21 . The front end of the front mold core 4 and the rear mold core 5 is provided with a tapered surface matching positioning structure 7 . The inner diameters of the front template hole 11 and the rear template hole 21 are the same and are processed at one time.

[0023] Since the hole diameters of the front template hole 11 and the rear template hole 21 are the same, the front template 1 and the rear template 2 are fixed together with guide posts and guide sleeve...

Abstract

The invention discloses a mould core embedding device of a small-bore plastic optical lens mould. The mould core embedding device comprises a front template and a rear template, wherein a front template hole is formed in the front template and a rear template hole is formed in the rear template; a front-mould mould core is arranged in the front template hole and a rear-mould mould core is arranged in the rear template hole; conical surface matching and positioning structures are arranged at the front ends of the front-mould mould core and the rear-mould mould core. The mould core embedding device of the small-bore plastic optical lens mould has the advantages that the aspheric-surface eccentric precision is improved, the core shift stability in the production is good and the like.

Description

【Technical field】 [0001] The invention relates to a small-diameter plastic optical lens mold core fitting device, especially for improving the eccentricity accuracy between two aspheric surfaces in plastic optical lenses with an outer diameter below Φ6mm and ensuring very stable eccentricity during production. Good lens mold structure. 【Background technique】 [0002] The traditional plastic lens mold structure is a mold core in a bushing or an integral mold core. Due to processing and matching errors, it can no longer meet the requirements of high eccentricity accuracy for mass production. With the continuous increase of mobile phone camera functions, the pixels of mobile phone lenses are also gradually increasing. Currently, the pixels of mobile phone lenses sold on the market have reached 8 million or even 13 million pixels, and there may be demand for higher pixel lenses in the future. [0003] However, with the increase of lens pixels, the requirements for lens eccentri...
