Example Embodiment

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] figure 1 and figure 2 A lens mold core according to an embodiment of the present invention is schematically shown.

[0016] The lens mold core includes an upper mold base 1 and a lower mold base 2 . The upper end of the lower mold base 2 is provided with a lower lens groove 4 . The upper mold base 1 includes a bushing part 11 and a sub-mould core 12 nested by the bushing part 11 .

[0017] A first positioning hole 111 , a second positioning hole 112 and a third positioning hole 113 are disposed inside the nesting component. The sub-mould core 12 includes a first positioning post 121 , a second positioning post 122 and a third positioning post 123 , and the first positioning post 121 , the second positioning post 122 and the third positioning post 123 are integrally formed. The first positioning column 121 is a cylindrical structure, the first pos...

Abstract

The invention discloses a lens mold core, and belongs to the field of lens molds. The lens mold core comprises an upper mold base and a lower mold base, a lower lens groove is arranged at the upper end of the lower mold base, the upper mold base consists of a bush component and a secondary mold core nested in the bush component, a first positioning hole, a second positioning hole and a third positioning hole are arranged inside the bush component, the secondary mold core comprises a first positioning column, a second positioning column and a third positioning column which are integrally formed and are correspondingly sleeved with the first positioning hole, the second positioning hole and the third positioning hole, and an upper lens groove is arranged at the front end of the first positioning column. The lens mold core has the advantages that processing precision of the lens mold core can be improved, the exhaust performance is excellent, and yield of large-diameter finished lens products is increased.

Description

technical field [0001] The invention relates to a lens mold, in particular to a lens mold core for manufacturing optical lenses. Background technique [0002] Ordinary precision optical plastic injection lens mold structure, the upper mold base of ordinary lens mold core is made of nickel-plated integrated structure, the accuracy of ordinary lens mold core is completely determined by the accuracy of correction during turning processing and the accuracy of processing equipment, resulting in the inability to self-adjust the accuracy, The manufacturing precision of the lens is not high during processing. When the product lens is a large lens, the glue position is deep and the area is large, which requires good exhaust performance, but ordinary lens molds have poor exhaust performance and cannot meet production needs. Moreover, the bottom of the upper mold base is formed through lateral processing when making ordinary lens mold cores, which is prone to flares and affects the...
