Embodiment Construction

[0023] 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.

[0024] 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 , the in-mold injection mold 100 includes: an upper mold 110 and a lower mold 120 . Wherein, an injection space 130 is defined between the upper mold 110 and the lower mold 120, and in the injection space 130, the difference between the maximum value D2 and the minimum value D1 of the distance between the upper mold 110 and the lower mold 120 is not greater than 10% of the maximum value D2 . Therefore, when the shell is prepared by using the mold, the filling thickness of the injection moldin...

Abstract

The invention discloses a mold for in-mold injection molding, a shell, a shell preparation method and a mobile terminal. Specifically, the mold for in-mold injection molding comprises an upper mold body and a lower mold body, an injection molding space is defined out between the upper mold body and the lower mold body, and in the injection molding space, the difference between the maximum value and the minimum value of the distance between the upper mold body and the lower mold body is not larger than 10% of the maximum value. Thus, when the shell is prepared through the mold, the filling thickness of an injection molding material in the injection molding space is even, the tensile force applied to an injection molding membrane layer during injection molding material solidification is even, accordingly, deformation of the shell is reduced, and the appearance of the shell is improved.

Description

technical field [0001] The invention relates to the field of electronic equipment manufacturing, in particular, to an in-mold injection mold, a casing and a preparation method thereof, 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, more and more mobile terminals such as mobile phones and tablet computers currently use integrated casings 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...
