Problems solved by technology

At present, the above-mentioned logo is pasted on the existing computer case by using an adhesive or the like. However, in order to paste the logo on the surface of the case, in addition to the process of manufacturing the case, a pasting process is also required. In addition, as time goes by, the sticking force of the label pasted by the adhesive becomes weak, and it is easy to fall off
In addition, when the logo is a three-dimensional design, since it protrudes outward, it is not only unsightly, but also has weak adhesive force

Abstract

The invention discloses a dual injection molding method of a built-in insertion piece and a built-in insertion piece type electric-device housing that produced by the method, wherein the method comprises the following procedures: separating a mobile mold of a first mold assembly from a fixed mold and opening the assembly; setting the insertion piece in the mobile mold of the first mold assembly; combining mobile mold of the first mold assembly with the fixed mold; transfusing a first transfusion liquor into a first mold assembly through an entrance for transfusing the transfusion liquor; opening the first mold assembly; moving a first injection molding product to the mobile mold of the second mold assembly; combining the mobile mold of the second mold assembly with the fixed mold; transfusing a second transfusion liquor into a second mold assembly through an entrance for transfusing the transfusion liquor; opening the second mold subassembly; and taking out the completed injection molding product from the second mold assembly. The electric-device housing produced by the method comprises a double structure that formed by an external surface and an interior surface and the insertion piece inserted between the two surfaces.

Description

technical field [0001] The present invention relates to a double injection (double injection, two-color injection or two-color double-material injection) forming method for external casings of electronic devices such as mobile phones, PDAs, and other portable terminals, desktop computers, and notebook computers, and electronic devices manufactured by the method. The external housing of the device. More specifically, a double-material injection molding method with built-in inserts such as a logo of a manufacturing company, and an external casing of an electronic device with built-in inserts manufactured by this method. Background technique [0002] At present, external casings of electronic devices such as desktop computers or notebook computers are usually manufactured by injection molding using a single mold. figure 2 and image 3 A front case 1 of a desktop computer and an upper case 10 of a notebook computer manufactured by such a method are shown. The surface of the c...
