Embodiment Construction

[0021] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0022] In one aspect of the invention, the invention proposes a mold for in-mold injection molding. According to an embodiment of the present invention, refer to figure 1 as well as figure 2 , the in-mold injection mold 100 includes: the mold includes: an upper mold 110 and a lower mold 120 . Wherein, the injection molding space 130 is defined between the upper mold 110 and the lower mold 120, and an external positioning area 140 (refer to figure 2 ). Moreover, at least one of the upper mold 110 and the lower mold 120 has a die positioning member 10 disposed on the outer positioning area. Thereby, it can be ensured that the injection diaphragm does not mov...

Abstract

The invention provides a mobile terminal shell, a preparation method thereof, a mould for IMD, and a mobile terminal. Specifically, the mould comprises an upper mould and a lower mould. The upper mould and the lower mould form an injection moulding space between the upper mould and the lower mould and an external positioning area that surrounds the injection moulding space. At least one of the upper mould and the lower mould is arranged on a position corresponding to the external positioning area and is provided with a membrane positioning member. Through abovementioned technical scheme, during the injection moulding process, an injection moulding membrane will not move relative to the mould, and thus the change of the membrane position is effectively prevented during the process of injection moulding. The mould can realize a positioning function without arranging a positioning member on the shell body.

Description

technical field [0001] The invention relates to the field of materials, in particular to an in-mold injection mold, a housing, a preparation method, and a mobile terminal. Background technique [0002] With the improvement of consumption level, consumers not only pursue the diversification of functions of industrial products, but also have higher and higher requirements for their appearance and texture. For example, current mobile terminals such as mobile phones and tablet computers increasingly adopt integrated housings with large arcs to improve user experience. In recent years, an in-mold decoration injection molding technology (Insert Mold Three-dimensional decoration, IMT, or called an in-mold injection molding 3D decoration technology) has been widely used in the field of manufacturing mobile terminal casings. The specific structure of the product formed by IMT can be a hardened transparent film on the surface, a printed pattern layer in the middle, and an injection m...
