Strain-induced semi-solid forming process and die for magnalium mobile phone shells

Abstract

Disclosed is a strain-induced semi-solid forming process and die for magnalium mobile phone shells. The process includes cutting a magnalium plate with certain compressive deformation into the suitable size, performing semi-solid heat preservation on the cut magnalium plate, and then putting the obtained magnalium plate with semi-solid characteristics into the preheated die for extrusion forming. The die comprises a mobile phone shell bottom cavity die device, the upper side of the mobile phone shell bottom cavity die device is connected with a mobile phone shell top terrace die device, die guide rods are assembled on the mobile phone shell top terrace die device, a left mobile phone shell core-pulling slider is connected to the left of the mobile phone shell bottom cavity die device, a right mobile phone shell core-pulling slider is connected to the right of the mobile phone shell bottom cavity die device, and mobile phone shell ejection mechanism is connected to the lower side of the same. The magnalium mobile phone shells with superior performance can be produced, and the process and the die have the advantages of simple process, high forming speed, low cost and the like.

Description

technical field [0001] The invention belongs to the technical field of communication products, and in particular relates to a strain-induced semi-solid forming process and a mold for a magnesium-aluminum alloy mobile phone casing. Background technique [0002] As a hand-held mobile communication terminal device with a high penetration rate, mobile phones have undergone several upgrades in just a few decades, becoming the epitome of technological progress. As the "skin" of the mobile phone, the mobile phone shell is the part that users directly contact. It is not only a powerful protective umbrella for the mobile phone, but also can effectively reduce the invasion of dust, reduce the damage caused by accidental drops, and enhance the service life of the mobile phone. The most important thing is to improve the user's product experience. Therefore, the materials for making mobile phone shells are required to have the characteristics of high strength, good heat resistance and t...

AI Technical Summary

Problems solved by technology

This method is suitable for mass production, high dimensional accuracy, stable quality, shortened production cycle, and improved productivity. However, during the forming process of the magnesium alloy mobile phone shell, the key components (inner screw and inner lining) in the injection machine are wear-resistant Poor performance and corrosion resistance, short service life and high maintenance costs
