Mold for manufacturing cylindrical mirror array

Abstract

The invention provides a mold for manufacturing a cylindrical mirror array. The mold comprises a male mold assembly, a female mold assembly and a runner assembly, wherein the female mold assembly comprises a box; an envelope in a cylindrical mirror shape is formed on the bottom surface of the box; the male mold assembly comprises a planar plate which serves as an upper cover plate of the box; the planar plate is matched with the box, and the edges of the planar plate and the box are tightly coupled; the runner assembly is connected with one side surface of the box; raw materials are injected into the box through the runner assembly. The mold for manufacturing the cylindrical mirror array is used for manufacturing the cylindrical mirror array by replacing a glass material with a high-light-transmittance PC (polycarbonate) material or a PMMA (polymethyl methacrylate) material, so that the process links for processing a cylindrical mirror can be reduced, good optical performance indexes can be achieved, and the cost is reduced. The mold is applicable to large-batch production.

Description

technical field [0001] The invention relates to the technical field of PTN networks, in particular to a mold for manufacturing cylindrical mirror arrays. Background technique [0002] In optical system design, aspheric optical parts can obtain better imaging quality than spherical optical parts. At the same time, using one or several aspheric parts instead of multiple spherical parts can simplify the component structure in the optical system. , effectively reduce the quality of components, and correct a variety of imaging deviations, improve imaging quality, and improve the performance of the optical system. [0003] Cylindrical lens is a common aspheric optical element. Its main function is that when a parallel light beam passes through the cylindrical lens, it can make the focal point be drawn into a line along one direction. It is widely used in various optical systems; it is composed of multiple The form of cylindrical mirrors forming an array is also widely used. Becau...

Problems solved by technology

[0005] 1) The process is complicated, there are many processing links, time-consuming and labor-intensive, and the cost is high

[0006] Glass cylindrical mirror arrays cannot be produced through moulds, and multiple cylindrical mirrors need to be processed and bonded separately. The main processes include cutting, rough grinding, fine grinding, polishing, precise measurement, bonding, etc., which is not conducive to mass production. Production, many process links cause high cost

[0007] 2) The bonding link is difficult to control and the defective rate is high

[0008] The cylindrical mirror array made of glass is composed of multiple single cylindrical mirrors bonded together. Before bonding, the single cylindrical mirrors need to be precisely measured, otherwise there will be defective products caused by insufficient processing precision of the single cylindrical mirrors; In the bonding process of the measured single cylindrical mirror, it is easy to have defective products caused by adhesive bubbles
