Method for manufacturing mobile phone casing with concave side wall and structure thereof

Abstract

The invention discloses a method for manufacturing a mobile phone casing with a concave side wall, comprising: an external mold manufacturing step, an internal mold manufacturing step, an impregnated fiber layer molding step, a heating forming step and a demolding step. Thus, by using an impregnated resin fiber layer as a forming material of the mobile phone casing, and matched to a forming mold formed by an elastic internal mold and a hard external mold, the method makes the side of the mobile phone casing break through the limit of demolding, so as to provide the mobile phone casing with various side walls, and the usage of the elastic internal mold makes it more reliable and rapider to form the mobile phone casing with the concave side wall, thereby reaching the purpose of form the concave side wall of the mobile phone casing.

Description

Technical field [0001] The invention relates to a manufacturing method and structure of a mobile phone casing, in particular to a manufacturing method and structure of a mobile phone casing with a concave side wall. Background technique [0002] General mobile phones such as figure 1 As shown, there are corresponding front and rear housings, and as shown in the back side housing in the figure, the conventionally known mobile phone housing 10 is mainly shaped as a structure with a concave opening 11, and the mobile phone housing 10 has A bottom wall 12 of the opening 11 and a side wall 13 connecting the opening 11 and the bottom wall 12; it is worth noting that, as figure 2 As shown, the manufacturing process of the conventionally known mobile phone housing 10 generally requires a molding die A to complete the molding step, where figure 2 As shown, the opening 11 that defines the concave mobile phone housing 10 has a width W on opposite sides, and there is a distance D between th...

Problems solved by technology

[0003] At present, 3C products are quite diverse. How to attract consumers with a design sense has become one of the keys to affect sales. Although some mobile phone product designers extend design changes to the side wall 13 and bottom wall 12 of the mobile phone casing 10 In terms of the shape of the bonding line, however, after considering the reduction of manufacturing costs, such as image 3 The width W of the opening 23 is smaller than the maximum distance D of the side wall 22 max Due to the problem of difficult demoulding, the side wall 13 of the known mobile phone housing 10 has not yet been removed from the aforementioned upright housing wall shape, which limits the design of the mobile phone housing 10. Therefore, the conventional mobile phone There is still room for improvement in the shell manufacturing method
