Problems solved by technology

[0005] (1) The high gloss of aluminum alloy, the effect after anodizing treatment is recognized by consumers, but the weight is relatively heavy;
[0006] (2) Magnesium alloy is light in weight and low in die-casting cost, but it is difficult to achieve the same bright appearance as aluminum alloy;
[0007] (3) At present, the combination of magnesium alloy and aluminum alloy is connected by welding, gluing, etc., which cannot be used on the appearance of the notebook shell

Embodiment Construction

[0044] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] The invention provides a die-casting method of a metal shell, the method comprising:

[0046] Firstly, the processed first metal alloy is fixedly arranged in the pouring space of the mould;

[0047] Next, converting the second metal alloy in the solidified state to the second metal alloy in the molten state;

[0048] Then, the second metal alloy in the molten state is injected into the casting space in the form of mold casting;

[0049] Finally, cooling the second metal alloy from a molten state into a solidified state, so that the first metal alloy and the second metal alloy form a metal shell, the shape of the metal shell matches the shape of the pouring space, wherein,

[0050] The first metal alloy is embedded on the...

Abstract

The invention provides a die casting method of a metal housing and an electronic device. The method comprises the following steps: fixedly arranging a processed first metal alloy into a pouring spaceof a die; converting the second metal alloy in a curing state into a second metal alloy in a melting state; pouring the second metal alloy in the melting state into the pouring space through the die;and cooling and converting the second metal alloy from the melting state into the curing state so as to form the metal housing with the first metal alloy and the second metal alloy, wherein the metalhousing fits the pouring space by shape; the first metal alloy is embedded o the second metal alloy in the curing state; and the first metal alloy is arranged on the outer surface of the metal housing. With the adoption of the die casting method, the whole metal housing is nice in appearance; and moreover, the metal housing is high in durability and good in use effect.

Description

technical field [0001] The invention relates to the field of metal die-casting, in particular to a die-casting method of a metal shell and electronic equipment. Background technique [0002] With the continuous development of science and technology, electronic equipment has also been developed rapidly, and there are more and more types of electronic products, and people have also enjoyed various conveniences brought by the development of science and technology. Now people can enjoy the comfortable life brought by the development of science and technology through various electronic devices. [0003] Equally, notebook computer is also more and more called the indispensable tool of people's work and leisure, and its outward appearance quality and weight are also more and more paid attention to by people. Therefore, how to achieve a high-quality appearance while being thinner and lighter in the design of the notebook is the theme pursued by the notebook design. [0004] In the...
