Embodiment 1

[0023] figure 1 It is a flowchart of a method for making a mobile phone middle frame provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of making a mobile phone middle frame, and specifically includes the following steps:

[0024] Step 110, making a mobile phone middle frame mold;

[0025] The mobile phone middle frame includes the mobile phone hardware middle plate and the plastic outer frame around the mobile phone hardware middle plate. Before injection molding, the mobile phone middle frame mold is made into the shape of the mobile phone middle frame. The mobile phone middle frame mold is used to inject engineering plastic alloy on the four sides of the mobile phone hardware middle plate to form the plastic outer frame of the mobile phone middle frame. Specifically, during injection molding, put the prepared mobile phone middle frame mold into the injection molding machine, then put the mobile phone hardware middle plate into the ...

Embodiment 2

[0057] image 3 It is a cross-sectional schematic diagram of a mobile phone middle frame structure provided in Embodiment 2 of the present invention. This embodiment provides a mobile phone middle frame structure, and the mobile phone middle frame structure is made by using any one of the mobile phone middle frames provided in Embodiment 1. methods, including:

[0058] The mobile phone hardware middle plate 20, the engineering plastic alloy 21 injected on the four sides of the mobile phone hardware middle plate 20, the coating 23 formed by electroplating on the outer surface of the engineering plastic alloy, and the antenna slit 24 formed by radium carving the coating 23 at the set position. Specifically, the above components together constitute the finished product 6 of the middle frame of the mobile phone.

[0059] In the technical solution of this embodiment, the engineering plastic alloy is injected on the four sides of the mobile phone hardware middle plate, and the oute...

Abstract

The present invention discloses a method for manufacturing a mobile phone middle frame and a structure of the mobile phone middle frame. The method for manufacturing the mobile phone middle frame includes the steps as follows: manufacturing a mobile phone middle frame die; injecting an engineering plastic alloy into four side faces of a hardware middle plate of the mobile phone through the mobile phone middle frame die to obtain a mobile phone middle frame workblank; spraying the upper surface and the lower surface of the mobile phone middle frame workblank except for the engineering plastic alloy region with anti-electroplating printing ink; electroplating the outside surface of the engineering plastic alloy region of the mobile phone middle frame workblank to obtain the mobile phone middle frame workblank with an electroplating layer; rejecting the anti-electroplating printing ink on the upper surface and the lower surface of the mobile phone middle frame workblank with the electroplating layer; and rejecting the electroplating layer of a setting position of the mobile phone middle frame workblank with the electroplating layer through the laser etching technique to expose the engineering plastic alloy as an antenna slot so that the finished mobile phone middle frame is obtained. According to the present invention, the outside face of the finished mobile phone middle frame is not prone to painting peeling off and has the better adhesive force, and the plastic outer frame of the finished mobile phone middle frame is more aesthetically pleasing.

Description

technical field [0001] Embodiments of the present invention relate to electronic equipment and communication technologies, and in particular to a method for manufacturing a mobile phone middle frame and a mobile phone middle frame structure. Background technique [0002] At present, the middle frame of a low-cost mobile phone generally adopts a metal middle plate, and then injects polycarbonate (Polycarbonate, PC) around it, and PC is a kind of strong and tough thermoplastic resin. Utilizing its strong and tough characteristics, the PC can be used as the outer surface of the finished product of the middle frame of the mobile phone. [0003] There are two main methods of treating PC on the outer surface of the middle frame of the mobile phone: spraying and vacuum plating. The defect that the outer surface is easy to peel off the paint. Contents of the invention [0004] The invention provides a method for manufacturing the middle frame of a mobile phone and a structure of...
