Embodiment Construction

[0023] Please also refer to figure 1 and figure 2 , the injection mold 100 of the preferred embodiment of the present invention is used to manufacture a shell 90 , and the shell 90 includes a base 92 and a soft layer 94 formed on the surface of the base 92 .

[0024] A preferred embodiment of the injection mold 100 is a rotary injection mold, which includes a first female mold 10, a second female mold 20 adjacent to the first female mold 10, a first male mold 30 and a second female mold 10. Male model 40.

[0025] The first female mold 10 is recessed with a first mold cavity 102 . The second female mold 20 includes a joint surface 202 opposite to the two male molds, and a second mold cavity 203 is recessed on the joint surface 202 . Two shearing parts 204 protrude from the joint surface 202 . The preferred embodiment of the two shearing parts 204 is two knife dies for cutting the soft layer on the semi-finished product of the casing 90 .

[0026] The first male mold 30 ha...

Abstract

The invention provides an injection mould which comprises a first female mould, a second female mould, a first male mould and a second male mould, wherein the first male mould and the second male mould are selectively and rotatably aligned and matched with the first female mould and the second female mould, and a cutting part is arranged on one female mould. Compared with the prior art, the injection mould can cut and process a soft layer of a half-finished product by the rotation to obtain a shell while manufacturing the half-finished product, cancels a step of cutting the soft layer by utilizing a die cutting tool or other cutting tools, greatly saves the processing time and improves the processing efficiency by rotating cycling processing.

Description

technical field [0001] The invention relates to an injection mold and a method for manufacturing a casing by using the same, in particular to a rotary injection mold and a method for manufacturing a casing with a soft layer by using the rotary injection mold. Background technique [0002] The housing is one of the main components of an electronic device, and it is widely used in electronic devices such as telephones, computers, and game machines. Since the material of the molded product itself has many advantages such as light weight, low cost, relatively simple processing technology, and corrosion resistance, most electronic devices use molded products formed by injection molding as their housings, such as plastics for manufacturing housings. s material. [0003] In order to further make the shell have a good sense of touch, a soft layer made of leather, fabric, etc. is used as the outermost layer of the shell in the prior art. In the process of manufacturing the shell, t...
