Abstract

The invention discloses a mobile phone shell forming method. The mobile phone shell forming method comprises the steps that a metal strip is welded into a rectangular frame body through bending, and a mobile phone frame is made; then a plurality of connecting pieces are welded and formed on the two inner sides of the mobile phone frame; and the mobile phone frame is arranged in a pressure casting die, and a middle plate is formed on the inner side of the mobile phone frame in a pressure casting mode. The connecting strength of the middle plate and the mobile phone frame is strengthened through the connecting pieces, and therefore, the strength of a mobile phone is strengthened; in addition, the mobile phone frame is formed by the metal strip through bending and welding, the production cost of the mobile phone frame can be reduced, and the strength of the mobile phone frame can be made higher than that of a mobile phone frame formed through machining according to the material mechanics and the material forming streamline science; and meanwhile, the appearance of the mobile phone has the good metal texture.

Description

technical field [0001] The invention relates to the field of mobile phones, in particular to a method for forming a mobile phone casing. Background technique [0002] With the development of science and technology, the mobile phone industry is constantly updated; from the previous pure plastic case to the metal case; there are two main types of metal mobile phone cases on the market; The outer frame and the middle plate are integrated; however, the manufacturing process of the outer frame and the middle plate is mostly formed by die-casting. [0003] The publication number is CN 106270460A Chinese Invention Patent discloses a method of manufacturing a mobile phone case, in which the method discloses that the solid metal part of the case in the shape of the mobile phone case is put into a die-casting mold, and then the die-casting material with a melting point lower than that of the solid metal part of the case is injected into the die-casting mold. Die-casting is carried ou...
