Embodiment Construction

[0023] The invention discloses a combined shell part and its in-mold injection molding method, which can effectively shorten the processing cycle. Through the structural design of the internal structural parts and the buckle position on the inner surface of the appearance aluminum material, the in-mold injection molding technology is adopted, so that the plastic can be injected. Produces a strong snap-fit ​​effect with internal structural parts and exterior aluminum.

[0024] The technical solution in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, what is described is only a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Abstract

The invention discloses a combination outer shell piece and an in-mould injection molding method. The combination outer shell piece comprises a combination outer shell and plastic components. The combination outer shell comprises appearance aluminum materials and an inner structure piece. Plastic connecting positions are arranged on the combination outer shell. The plastic connecting positions are placed on the inner surface and the side face of the appearance aluminum materials and the upper surface of the inner structure piece. The plastic components are formed on the upper surface of the inner structure piece and the inner surface of the appearance aluminum materials in an injection moulding mode. By using in-mould pressure casting and the in-mould injection molding method, the problem that according to an existing combination outer shell piece, a machining process is complex, and the combining force of an outer shell body and plastic is poor is solved.

Description

technical field [0001] The invention belongs to the field of processing plastic parts of combined shell parts, and in particular relates to a combined shell part and an in-mold injection molding method thereof. Background technique [0002] The casing is a necessary setting for mobile phones and tablet computers. The materials of the casings of different mobile phones and tablets are diversified. Stainless steel, aluminum alloy, carbon fiber, etc. are often used as the basic casings. When producing the casings, not only the casings must be considered In addition to the quality and toughness of the body, its aesthetics must also be considered. The existing technology is to carry out CNC machining and molding through a whole board. This method is complicated to process, requires more processing machines, and has higher requirements for processing materials. [0003] On the other hand, it is usually necessary to add some functional plastic parts to the casing of mobile phones a...
