Mobile phone battery case and forming process thereof

Abstract

The invention discloses a mobile phone battery case. The mobile phone battery case comprises a metal case and plastic parts fixedly connected to the metal case, wherein the metal case comprises a metal frame and a metal cover board, the metal cover board and the metal frame form an integrated structure, and a partial hollow structure is formed at a position where the metal cover board is connected with the metal frame; the plastic parts consist of a plastic frame and a plastic filling part, the plastic frame and the plastic filling part form an integrated structure, the plastic frame is in tight contact with the metal frame at the inner side of the metal frame, and the hollow structure is filled with the plastic filling part. The invention also discloses a forming process of the mobile phone battery case. By adopting the mobile phone battery case, the appearance expression of the mobile phone product is guaranteed, the structure of the metal case is simplified, the thickness of the metal case is reduced, the processing difficulty and the product cost are reduced, and the product productivity is improved; by adopting the process, the production efficiency is improved while the production quality of the product is guaranteed.

Description

technical field [0001] The invention relates to the technical field of metal and plastic composite molding, in particular to a mobile phone battery case and a molding process thereof. Background technique [0002] Most of the shells of mobile phones sold on the market are made of plastic, and various effects can be achieved by spraying various paints on the plastic shell, but the wear resistance of the plastic shell is poor, and the strength of the overall structure of the mobile phone Not enough, easily damaged or scratched. [0003] Therefore, the current mobile phone battery cover is often made of metal materials, especially aluminum alloy, to match the surface shell or middle shell made of aluminum alloy, and jointly improve the grade of the mobile phone. [0004] The structure of the mobile phone case usually requires the outer surface facing the outside of the mobile phone to be smooth, while the inner surface facing the inside needs to be provided with more complicat...

AI Technical Summary

Problems solved by technology

The mobile phone case made of metal materials will encounter great difficulties in the processing of the internal connection structure and positioning structure. The processing technology is complicated, the processing time is long, the mass production is poor, and the production cost is high.

At the same time, in order to ensure the quality of the product, the metal material needs to have a larger thickness, which increases the cost of raw materials.
