Manufacturing process for aluminum-containing die-casting shell capable of anodic oxidation

Abstract

The invention provides a manufacturing process for an aluminum-containing die-casting shell capable of anodic oxidation. The die-casting shell is designed into two portions, one is an internal structural component, and the other is an exterior component which encircles the outer periphery of the internal component. Firstly, machine shaping is conducted on the exterior component, the exterior component is arranged in a die-casting mold, metal liquid is poured so that the exterior component and the internal component are casted into a whole to be the shell, and the anodic oxidation process is conducted on the die-casting shell. The manufacturing process for the aluminum-containing die-casting shell capable of anodic oxidation has the advantages of applying the technology of the anodic oxidation to the aluminum-containing die-casting shell, reducing the manufacturing procedures of CNC, saving the production cost, improving the product yield and the dimensional precision, and reducing the waste of aluminum alloy material, the equipment of CNC and the investment of human resources.

Description

technical field [0001] The invention relates to the field of manufacturing metal casings, in particular to a method for manufacturing a die-casting casing containing aluminum. Background technique [0002] The progress of the times has made electronic products indispensable in people's lives. The electronic product market continues to develop. Mobile phones, e-books, notebooks, tablet computers and other wearable devices have become popular in people's lives. People's demand for electronic products Higher and higher requirements are not only reflected in performance, but also in appearance. The fierce competition in the market has caused major electronic product casing manufacturers to continuously develop new manufacturing technologies in order to obtain high-efficiency and low-cost manufacturing methods to seize the market. status. [0003] In the Chinese patent application publication number "CN101862821A", the application publication date is October 20, 2010, and the in...

AI Technical Summary

Problems solved by technology

[0005] 1. There are many CNC processing procedures and many clamping times, which require a lot of human resources;

[0006] 2. The efficiency of each process is low, resulting in a long time for the process;

[0007] 3. The utilization rate of alloy materials is low;

[0008] 4. A large amount of CNC equipment needs to be invested to meet the production demand, and the equipment cost is high;

[0009] 5. Insufficient processing precision and low yield rate

[0010] If the die-casting process is used to make the die-casting shell, although the shell forming efficiency and product precision are higher than those of the CNC processing process, the surface quality of the aluminum alloy die-casting parts cannot meet the user's requirements after anodic oxidation, and there are aluminum alloy parts made by the die-casting process. Technical difficulties that cannot be anodized
