Embodiment 1

[0032] refer to figure 2 , is the first mobile phone casing according to the specific embodiment of the present invention. Such as figure 2 The first-type mobile phone case includes a first-type shell 1 extruded from plastic material, a first-type window opening 11 , a first-type stepped portion 12 and a first-type mounting hole 13 . The first type of casing 1 is an overall structure in which the upper and lower casings of the mobile phone are connected; 11 is used for installing mobile phone window 15, as touch screen, lens etc.; This first kind of stepped part 12 is positioned at the limit of first kind of window opening 11, and this first kind of stepped part 12 can support mobile phone window 15, is convenient to window 15 is installed on the opening 11 of the first type of window; the first type of mounting hole 13 is set at the end of the first type of housing 1 in a semi-closed ring shape, and the internal components of the mobile phone are installed to the mobile p...

Embodiment 2

[0048] refer to Figure 4 , is the third mobile phone shell of the specific embodiment of the present invention. Such as Figure 4 , the third type mobile phone case includes a third type shell 3 and a third type installation hole 32 formed by extruding plastic material. The third type of housing 3 is an overall structure in which the upper and lower casings of the mobile phone are connected and also includes a transparent window 31, which is extruded from transparent plastic material; the third type of mounting hole 31 is arranged on the third type The end of the housing 3 is in a closed ring shape, and the internal components of the mobile phone are installed on the mobile phone through the third type of mounting hole 32 .

[0049] For the third mobile phone casing, one or more plastic materials can be used for extrusion molding with two extruders, wherein the plastic materials should include at least one transparent plastic material, and the extruder is a single-screw ext...

Abstract

The invention relates to a mobile phone shell and a manufacturing method thereof. The mobile phone shell comprises a shell body made by plastic extrusion, the shell body is in an integral structure formed by connecting an upper shell and a lower shell, and the ends of the shell body are provided with mounting holes for mounting of internal parts of a mobile phone. The manufacturing method of the mobile phone shell includes: providing plastic materials; sending the plastic materials into a drying oven for drying; sending the dried plastic materials into an extruder; heating, plasticizing and extruding the plastic materials through a gate mould of the extruder to form a continuous part similar to the gate mould in shape; subjecting the continuous part to cooling forming; and drawing and cutting the continuous part subjected to cooling forming. The mobile phone shell is attractive in appearance and does not affect signals of mobile phone antennas. The manufacturing method of the mobile phone shell is low in cost and high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of mobile phone casings, in particular to a mobile phone casing and a manufacturing method thereof. Background technique [0002] At present, mobile phones are generally assembled from components and upper and lower casings, such as figure 1 As shown in the mobile phone, this kind of mobile phone includes an upper casing, a lower casing and internal components. When assembling, the internal components of the mobile phone are usually installed on the lower casing first, and then the upper casing is fastened by buckles, screws, etc. The casing is fixedly connected with the lower casing to complete the entire assembly process. This kind of assembled mobile phone, no matter how precise the assembly is, there will be gaps between the upper case and the lower case, because the assembly also requires assembly tolerances, such a mobile phone does not look good enough, and it is difficult to satisfy consumers The p...
