The method has simple process and low manufacturing cost, and the manufactured optical mold has a three-dimensional texture structure, is different from a common plane optical product, has unique visual and tactile effects, and realizes the differentiation of the optical product.
The design process of the texture structure design graph comprises the following steps: on a reference plane, firstly designing a group of space curves, wherein the group of space curves comprises a plurality of space curves, the space curves are curves with fluctuating changes in three-dimensional space, and the space curves in the group extend along the same direction; secondly, a plurality of groups of space curve groups with the same or different extension directions can be obtained according to the design method; and finally, forming the texture structure design graph after at least two groups of space curves are overlapped on a reference plane. The physical structure pattern designed by the method has a unique visual effect of fluctuation, and differentiation of optical die products is guaranteed.
In the embodiment of the present invention, optionally, the line width of each of the space curves is 50 to 80 μm. Preferably, the line width of the space curve is 60 μm. The line width of the space curve within the numerical range can make the finally obtained texture structure pattern have good visual effect.
Optionally, the distance between two adjacent space curves is 30-50 μm. Preferably, the spacing between two adjacent space curves is 40 μm. The space curve spacing in the numerical range can avoid that the texture structure cannot be formed due to improper curve arrangement caused by too close or too far distance between the space curves.
Optionally, after the manufacturing of the optical mold, the method further includes: and cleaning the optical mold by adopting an ultrasonic technology. The ultrasonic technology is adopted to clean and finish the optical mould, so that a clearer optical mould is obtained, and burrs on the mould are prevented from influencing the smoothness of the texture structure graph.

step 61: dripping glue on the optical mould with the texture structure manufactured by the method;
step 62: transferring the glue on the optical mold onto an explosion-proof membrane;
and step 63: and curing the glue on the explosion-proof membrane to obtain the explosion-proof membrane with the texture structure.
By the method, the three-dimensional patterns consistent with the texture structure on the optical mold can be formed on the explosion-proof membrane, so that the explosion-proof membrane has the texture structure with a special visual effect, and the surface of the explosion-proof membrane, on which the three-dimensional patterns are transferred, has a larger friction force, so that the anti-skid effect can be achieved.
Optionally, after the glue on the rupture disk is cured, the method further includes: and coloring the texture structure surface by a sputtering coating process. Specifically, the texture structure surface of the explosion-proof membrane with the texture structure pattern transferred is protected by a protective membrane, and the texture structure surface is subjected to optical coating: firstly, tearing off a protective film covered on the texture, putting the whole explosion-proof film into an optical plating furnace, and plating the texture structure surface of the explosion-proof film; secondly, adjusting control parameters of a plating furnace baffle and an optical plating furnace, and plating required colors on the texture structure surface, wherein the colors can be colorful, pure or any required gradient colors; and taking out the explosion-proof membrane after the explosion in the optical plating furnace for about 50-60 minutes, wherein the non-texture structure surface of the explosion-proof membrane is protected by a protective membrane.
After the optical coating process is finished, processing the explosion-proof film by adopting a screen printing process: tearing off the protective film covered on the non-texture structure surface of the protective film after the color plating is finished, adsorbing the protective film on a screen printing table with the mesh number of 350, and adjusting the position for printing; and printing black ink on the non-texture structure surface, placing the non-texture structure surface on a frame after printing, waiting for baking, wherein the baking temperature is 40 ℃, the baking time is 45 minutes, repeating the operation, brushing the ink for 3 times, and baking for 3 times, so as to achieve the effect of thoroughly shading the non-texture structure surface of the explosion-proof membrane.
The explosion-proof membrane with the texture structure obtained by the coloring and screen printing process has a visual effect like colored glaze, and has an anti-skid effect due to the fact that the explosion-proof membrane has the three-dimensional texture structure.
In the embodiment of the invention, the glue is an optional UV glue, and the glue can be cured by adopting ultraviolet light.
