Jet molding method for notebook computer envelope

Abstract

The invention relates to a method for injection molding the frame of notebook computer. Wherein, the plastic injection mould and rubber injection mould are both mounted on the rotary table of injection machine; then processing the first injection molding in the plastic injection mould, that uses one injection device to fill plastic material into the chamber of plastic injection mould to form the semi-finished product; the public mould of plastic injection mould with its semi-finished product and the public mould of rubber injection mould exchanges positions by the rotation of rotary table; then processing the second injection molding, that using the injection device of injection rubber to inject rubber material into the chamber of mould that contains semi-finished product, to obtain one finished product, as well as processing the first injection molding to form one semi-finished product in the chamber of another mould; getting out the final product, and repeating aforementioned operations, therefore, with said continuous production, the yield and product quality can be improved.

Description

【Technical field】 [0001] The invention relates to a manufacturing method of a notebook computer shell, in particular to an injection molding method for producing a notebook computer shell by combining multiple materials. 【Background technique】 [0002] At present, notebook computers have become an indispensable part of life entertainment and business activities. Commonly used notebook computers include an upper cover with a display screen and a lower cover composed of a host and a keyboard. One end of the upper cover and the lower cover It is fixed by the rotating shaft, so that the upper cover can be lifted at an appropriate angle for operation, and the other end of the upper cover and the lower cover is through a male card lock set on the lower cover and a lock set on the upper cover. The mutual cooperation of the female latches of the computer achieves the closed state of the computer, that is, the upper cover with the display screen can be closed on the lower cover when ...

Problems solved by technology

However, due to the manual assembly method, the positioning between the rubber film and the computer case is not very accurate, and the problem of gaps is still prone to occur. Moreover, the manufacturing process of manual assembly is complicated, the production capacity of the product is low, and the defect rate is high.

Furthermore, because the materials of the laptop case and the rubber film are different, changes in the external temperature and humidity may cause the rubber film to fall off from the laptop case, which not only affects the appearance of the case, but also affects the normal use of the laptop.
