Electronic product shell, injection molding method and manufacturing method

Abstract

The invention relates to an electronic product shell adopting a novel glue pulling structure, which comprises a metal shell and a plastic structure, and is characterized in that the glue pulling structure is arranged at the position, corresponding to the plastic structure, of the inner side wall of the metal shell, and the glue pulling structure comprises a longitudinal groove and a transverse groove; the plastic structure is provided with connecting parts with corresponding shapes at positions corresponding to the longitudinal grooves and the transverse grooves, and the plastic structure is fixedly connected with the metal shell through the connecting parts. According to the invention, the longitudinal groove and the transverse groove are respectively formed in the metal shell, so that the plastic structure formed by injection molding is fixed with the metal shell in multiple directions, and the connection is firmer; and the stress is more uniform, the requirement on the thickness of the rubber pulling structure is lower, the thickness of a metal plate used for producing the metal shell can be reduced to 2mm, and the cost of raw materials is reduced.

Description

technical field [0001] The invention belongs to the technical field of electronic product casing processing, and relates to an electronic product casing adopting a novel rubber-pulling structure, an injection molding method and a manufacturing method. Background technique [0002] The electronic product casing processing industry is highly competitive, and more and more electronic product casings are processed by forging and forming aluminum-plastic combination to reduce processing costs. like figure 1 and figure 2 As shown in the figure, when using the traditional processing technology to combine aluminum and plastic to process the electronic product casing, it is necessary to mill the through hole 91 on the metal shell 1 first, and then mill the groove 92 on the outer side wall of the metal shell 1 corresponding to the position of the through hole 91 , the T-shaped groove 9 is formed by the through hole 91 and the groove 92 as the rubber-pulling structure; but the rubbe...

Problems solved by technology

like figure 1 and figure 2 As shown, when adopting the traditional processing technology to process aluminum-plastic composite shells of electronic products, it is necessary to first mill a through hole 91 on the metal shell 1, and then mill a groove 92 on the outer wall of the metal shell 1 corresponding to the position of the through hole 91. , through the through hole 91 and the groove 92 to form a T-shaped groove 9 as a rubberized structure; however, the rubberized structure of this aluminum alloy has a higher requirement for the thickness of the side wall of the metal shell 1, and the thickness of the side wall needs to be above 4mm , which requires that the thickness of the raw materials used to produce electronic product casings must also be above 4mm, but after the production of electronic product casings such as mobile phones, the thickness of most positions is far less than 4mm, which makes the effective use of raw materials lower. higher

Moreover, the use of this processing technology makes the processing time longer
