Problems solved by technology
However, the first-line bifocal prism lacks production molds. The traditional production process is to directly process the semi-finished lens in the workshop, rather than one-time molding like ordinary lenses. The workshop processing requires high-cost introduction of advanced equipment and equipment procedures, and cannot be mass-produced. The production process of the first-line bifocal prism is time-consuming and laborious, and the efficiency is low

Embodiment Construction
[0026] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments.
[0027] A manufacturing process for a first-line bifocal prism sheet mold, comprising manufacturing a back mold, the step of manufacturing the back mold includes:
[0028] Step S1: Make the first mold piece, the second mold piece and the third mold piece with the same base curvature and consistent diameter, wherein the first mold piece and the second mold piece are of ordinary spherical surface type, and the first mold piece is more than The second mold sheet is thin, and the third mold sheet is a spherical surface type with prisms;
[0029] Step S2: Scribing the second mold sheet to obtain a glazing mold sheet, and scribing the third mold sheet along the line connecting the thinnest position and the thickest position of the third mold sheet to obtain a lower glazing mold sheet; wherein,
[0030] ...

Abstract
The invention discloses a manufacturing process of a one-line bifocal prism sheet mold. The step of manufacturing the rear mold includes: step S1: making a first mold sheet, a second mold sheet and a third mold sheet with uniform base curvature and diameter, The first mold sheet and the second mold sheet are ordinary spherical surfaces, and the third mold sheet is a spherical surface with prisms; step S2: scribing the second mold sheet to obtain a polishing mold sheet, and Scribing the third mold sheet in the direction of the connection line between the thin position and the thickest position to obtain the lower light mold sheet; step S3: polishing the cross-section of the upper light mold sheet and the lower light mold sheet, so that the upper light mold sheet and the lower light mold sheet It can be spliced into a circular shape; step S4: paste the non-working surfaces of the polished glazing mold sheet and the lower glazing mold sheet on the surface of the first mold sheet to become a preformed rear mold; step S5: curing. The invention can manufacture a mold for a one-line double-light prism sheet, thereby enabling mass production of the one-line double-light prism sheet and reducing production costs.
Description
technical field [0001] The invention relates to a manufacturing process of a one-line bifocal prism sheet mold. Background technique [0002] Ordinary lenses are formed by filling resin monomers into lens molds and polymerizing them. However, the first-line bifocal prism lacks production molds. The traditional production process is to directly process the semi-finished lens in the workshop, rather than one-time molding like ordinary lenses. The workshop processing requires high-cost introduction of advanced equipment and equipment procedures, and cannot be mass-produced. As a result, the production process of the first-line bifocal prism is time-consuming and laborious, and the efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide a manufacturing process of a one-line double-light prism sheet mold, which can easily manufacture a one-line double-light prism ...
