Abstract

The invention provides a forging mould and a molding method of a metal casing applied to an electronic device. A metal plate can be molded in a forging and pressing mode into a blank of the metal casing with less following machining quantity through the mould, and the blank of the casing is subjected to a small amount of machining to form the metal casing. The mould and the method solve the problem in the prior art that the metal casing of the electronic device is long in machining time, the blank of the casing with less following machining quantity cannot be molded, production cost is high, material utilization rate is low and the like.

Description

technical field [0001] The invention relates to a forging mold and a forming method applied to a metal shell of an electronic device. Background technique [0002] The shape of a 3C electronic device (Computer, Communication and Consumer electronic) is generally a flat rectangular parallelepiped. Its shell is usually a thin drawer-like concave shape, and a shell cavity is surrounded by a central thin web and surrounding frame substructures. The outer front surface of the shell is generally a plane, but it can also be designed as an arc. The outer surface of the surrounding frame is a plane or an arc surface. The web and frame in the concave cavity are usually designed with a web substructure and a frame substructure, as a structure for installing other components (such as studs, bosses, buckles and hinged edges, etc.) or as a strengthening structure for the shell (such as Reinforcing ribs and ribs, etc.). Human-machine communication interfaces such as display screens and...
