Mobile phone rear shell and manufacturing method of mobile phone rear shell

Abstract

The invention provides a manufacturing method of a mobile phone rear shell. The manufacturing method comprises the following steps: providing a composite film; forming a first camera mounting hole in the composite film; providing an injection mold including a front mold and a rear mold; arranging a suction groove and a suction device on the front mold; setting a locating piece, a first pitched roof and a second pitched roof on the mold core of the rear mold; arranging the composite film in the mold cavity of the front mold; adsorbing the composite film by virtue of the suction device; ejecting the composite film by virtue of the locating piece and the first pitched roof; injection-molding a required plastic main body by virtue of the injection mold; and forming a second camera mounting hole on the plastic main body. By arranging the locating piece and the first pitched roof on the mold core of the rear mold, the manufacturing method disclosed by the invention, besides locating the composite film, can be used for guaranteeing that locating holes of the locating piece and the first pitched roof formed on the plastic main body are covered by the composite film, so as to avoid the formation of through holes on the mobile phone rear shell and to effectively guarantee the exquisite appearance of the mobile phone rear shell. Furthermore, the invention also provides the mobile phone rear shell.

Description

technical field [0001] The invention relates to the technical field of mobile phone casings, in particular to a method for manufacturing a mobile phone rear casing and a mobile phone rear casing manufactured by the method. Background technique [0002] In order to avoid homogeneity and to highlight personality and fashion, the current mobile phone back shell generally adopts the following methods to achieve: [0003] 1. IML (membrane in-mold injection molding) method, specifically, the texture and color are printed on the PET sheet, and then injected in the mold. However, this method needs to open positioning holes on the surface of the rear case, and this method will affect the appearance of the mobile phone rear case. Moreover, the texture of the mobile phone rear case is poor in 3D texture, and it is difficult to meet consumers’ requirements for high-quality mobile phone rear cases. [0004] 2. The method of pasting the textured diaphragm, specifically, first make the te...
