Die casting technology of notebook computer shell

Abstract

The invention relates to the technical field of electronic product production, in particular to a die casting technology of a notebook computer shell. Magnesium alloy is used as raw material, and thenotebook computer shell is prepared through using a die casting machine. The die casting technology comprises the following steps of S1, material dissolution; S2, ejection of molten alloy; S3, cooling; and S4, product ejection. A mold comprises a fixed mold, a movable mold and a material injection pipe used for connecting the fixed mold and the movable mold; the die casting machine is provided with a centralized exhaust plate used for exhausting, a mirror-surface discharge current channel and a plurality of oil circuits distributed in a die blank; and the centralized exhaust plate is providedwith a plurality of strip-shaped grooves, and the exhaust positions on the two sides of the centralized exhaust plate are set to be wavy. Due to the specific arrangement of the die casting machine andthe mold and the arrangement of various parameters, the thickness of the die casting part can be thinned to be 0.4 mm. Therefore, a thinner product can be prepared by the die casting technology of the notebook computer shell, material waste can be avoided, the reject ratio is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic product production, in particular to a die-casting process for a notebook computer casing. Background technique [0002] With the development of science and technology, the application of electronic products is becoming more and more extensive. Wherein, notebook computer is the electronic product that people usually use. With the pursuit of thinner and lighter electronic products, each accessory of electronic products must continue to pursue thinner and lighter, in order to meet the requirements of thinner and lighter electronic products. [0003] Among them, in a notebook computer, the casing is an important part for carrying electronic components. At present, the casings of notebook computers in the prior art are mostly prepared by injection molding or die-casting of aluminum alloy and magnesium alloy. However, in the prior art, the thickness of notebook computer shells prepared by die-cas...

Problems solved by technology

However, in the prior art, the thickness of notebook computer casings prepared by die-casting technology is 0.6-1.5 mm, which cannot meet the requirements of light and thin electronic products.

[0004] Under the demand of the market, the existing technology attempts to cast a computer case with a thickness of 0.5mm, but there is a defect that the die-casting defect rate is high, which leads to an increase in production costs.
