Abstract

The invention discloses a metal die casting shell forming method. The method comprises the steps that a metal alloy material in a cured state is converted into a metal alloy material in the melted state; the metal alloy material in the melted state is injected in pouring space of a die in a die pouring manner; the metal alloy material in the melted state is converted into the metal alloy material in the cured state in a high-pressure cooling manner so that a shell can be formed, and the shell is matched with the pouring space in shape; the die is separated, and the shell is taken out; and the shell is subjected to surface treatment, and therefore the shell of an intelligent electronic device is formed. The metal shell of the intelligent electronic device is formed in a die pouring manner.

Description

technical field [0001] The disclosure relates to a method for forming a metal die-casting shell, in particular to a method for forming a metal die-casting shell for a mobile phone. The disclosure also relates to an intelligent electronic device, the metal casing of which is formed by mold casting. Background technique [0002] At present, the processing technology of the metal shell of the mobile phone is to use the material metal plate to process through the computer numerical control machine tool (Computer Numerical Control). The parts after the above machining are then combined with metal and plastic with nano-technology (Nano Molding Technology), that is, after the metal surface is nano-treated, the plastic is directly injection-molded on the metal surface, so that the metal and plastic Can be integrally formed. Finally, coloring is done. [0003] There are following defectives in above-mentioned traditional craft: [0004] 1. The CNC machining process is cumbersome ...
