AI Technical Summary

Problems solved by technology

More specifically, micromachining of resin molds using CNC machining has a problem that the resin of the resin mold is melted by cutting heat, so that a sharp reverse image cannot be engraved on the resin mold, and because the resin Resin molds are insulators and chemically resistant, so resin molds cannot be micromachined with charge machining or etching
Therefore, resin molds, which are easy-to-use molds, cannot be micromachined

Abstract

A surface micromachining process for a resin mold including a layer of a resin as a material of the resin mold, which layer has a product's surface forming plane, and a back surface reinforcing member for reinforcing the resin layer. The product's surface forming plane is micromachined by means of at least two masking / blasting treatments. The treatments comprise a primary blasting step of sticking a first mask sheet having a specific window on the product's surface forming plane and blasting blast particles to the product's surface forming plane via the first mask sheet, and a secondary blasting step of peeling the first mask sheet, sticking a second mask sheet different from the first mask sheet on the product's surface forming plane, and blasting blast particles to the product's surface forming plane via the second mask sheet.

Description

technical field [0001] The present invention relates to a surface micromachining method for a product surface forming surface of a micromachining (micromachining) resin mold. Background technique [0002] As molds for injection molding resins, metal molds have been mainly used, and in some cases, such as trial production or small-lot production, resin molds have been used. [0003] The resin mold disclosed in Japanese Patent Laid-Open No. 2001-105438 entitled "Method for Producing Resin Mold" is characterized in that one face facing the cavity, that is, the product surface forming face of the resin mold is made of resin. become. [0004] The exterior surface of a resin product such as a handle cover, trunk, fender, or sheet floor of a two-wheeled vehicle (motorcycle or scooter type vehicle) has been considered as a decorative design surface, and attempts have been made to Add exquisite patterns to the decorative design surface of resin products. [0005] In connection the...
