A manufacturing process of anodizable aluminum-containing die-casting shell

Abstract

The invention provides a manufacturing process of anodized aluminum-containing die-casting shell. The die-casting shell is designed into two parts, one is the inner structural part, and the other is the outer appearance part surrounded by the inner structural part. First, the outer appearance part is processed and shaped, Then arrange the appearance parts in the die-casting mold, and then pour molten metal to die-cast the appearance parts and the inner structural parts into an integrated shell, and carry out the anodizing process on the die-casting shell. The advantage of the present invention is that the anodizing technology can be applied On the aluminum-containing die-casting shell, the CNC processing process is reduced, the production time is saved, the product yield and dimensional accuracy are improved, the waste of aluminum alloy materials is reduced, and the input of CNC equipment and human resources is reduced.

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
