Abstract

The invention discloses a machining method of a mold core with a micro truncated cone array on the surface. The machining method comprises the following steps that S1, a metal workpiece is taken, and the surface of the metal workpiece is machined to a smooth plane; S2, a machining tool is used for carrying out linear path array machining on the machined smooth plane in the first direction, a preliminary machining surface is obtained, and array machining is carving or planing; and S3, the machining tool is rotated according to the angle alpha, the angle alpha ranges from 80 degrees to 100 degrees, then the machining tool is used for conducting snakelike path array machining on the preliminary machining surface in the second direction, and therefore the micro truncated cone array is formed on the surface of the metal workpiece, the mold core with the micro truncated cone array on the surface is obtained, and array machining is carving or planing. According to the mold core, with the micro truncated cone array on the surface, manufactured through the method, the machining efficiency is greatly improved, the machining process is greatly simplified, and the precision of the obtained micro truncated cone array morphology can be effectively guaranteed.

Description

technical field [0001] The invention relates to the field of microstructure array processing, in particular to a method for manufacturing a mold core with a microtruncated pyramid array on the surface of a road traffic reflective film. Background technique [0002] The microprism type reflective film made by using the principle of refraction and total reflection of the microprism array structure has a fine pyramid structure on the inner surface through the micro-nano copy transfer technology array. When the external lighting source shines on the reflective film, Through the multiple reflections and refractions of the pyramid structure inside the reflective film, the incident light will be reflected back along the incident direction of the light. No built-in power supply or light source is required, and the reflected light has no stray light interference. It has the characteristics of strong warning, high recognition, energy saving and environmental protection in dark environ...
