Abstract

The invention discloses a method for molding a two-color solid silica gel. The method includes the steps of first-time silica gel molding, specifically, a first color silica gel raw material is subjected to vulcanization molding to form a first-time silica gel product with a blind hole; second-time silica gel molding, specifically, a second color silica gel raw material is subjected to second-timevulcanization molding on the face, provided with the blind hole, of the first-time silica gel product; and laser carving, specifically, a silica gel layer attached into the blind hole is removed by laser carving to reveal the required color of a first color silica gel layer. The invention further provides a product, a mold and application formed by the method for molding the two-color solid silica gel. According to the method for molding the two-color solid silica gel, the silica gel layer attached in the blind hole is removed by using a radium engraving machine after the two silica gel raw materials with different colors are molded twice, thus the silica gel raw materials with different colors formed successively are fused without penetrating each other, a through-hole structure on the middle of a second color silica gel layer can be realized, and then color bias is avoided when light passes through the two-layer silica gel of the two-color solid silica gel molding product.

Description

technical field [0001] The invention relates to the technical field of silica gel molding, in particular to a method for molding two-color solid silica gel and its product, mold and application. Background technique [0002] With the continuous improvement of people's living standards and the continuous advancement of science and technology, various electronic / communication products with buttons continue to emerge, such as mobile phones, electronic dictionaries, handheld computers (PDAs) and handheld game console buttons. These products currently use a large number of two-color silicone products. The usual low-cost method is to put different colors of rubber materials into the mold cavity at the same time for hydraulic molding (this method is also called raw material one plus raw material two) However, when the silicone material is heated and vulcanized, the rubber materials of different colors penetrate into each other, resulting in mixed colors, uncontrollable borders and ...
