Mobile phone, mobile phone rear shell with touch pad operation function and manufacturing method thereof

Abstract

The invention relates to the field of intelligent terminal design, in particular to a mobile phone, a mobile phone rear shell with a touch pad operation function and a manufacturing method thereof. The mobile phone comprises the rear shell with the touch panel operation function, wherein the rear shell is manufactured by adopting a touch pad IMR process injection mold. According to a hidden spruesystem adopted by the method, the technical problem that plastic material flow cannot be flushed and flanged to be injected onto the surface of the diaphragm, namely problem of the glue leakage in injection molding, is solved.

Description

technical field [0001] The invention relates to the field of intelligent terminal design, in particular to a mobile phone, a mobile phone rear case with a touch panel operation function and a manufacturing method thereof. Background technique [0002] At present, the screen of smart phones tends to be large-screen, and the operation requires one hand to hold the mobile phone and the other hand to operate the screen, which can be completed with the cooperation of both hands, which brings inconvenience to users; A smart phone with a touchpad operation function on the back shell, this technology belongs to the prior art, however, in the prior art, the injection mold manufacturing process for the back shell of the mobile phone with the touch panel operation function is inefficient, and the existing The mobile phone back shell with the touch panel operation function manufactured by injection molding needs to be improved in terms of structural strength, sealing performance, and an...

[0002] At present, the screen of smart phones tends to be large-screen, and the operation requires one hand to hold the mobile phone and the other hand to operate the screen, which can be completed with the cooperation of both hands, which brings inconvenience to users; A smart phone with a touchpad operation function on the back shell, this technology belongs to the prior art, however, in the prior art, the injection mold manufacturing process for the back shell of the mobile phone with the touch panel operation function is inefficient, and the existing The mobile phone back shell with touchpad operation function made of injection mold needs to be improved in terms of structural strength, sealing, and anti-aging performance

[0003] The IMR process is to place a part of the continuous sheet in the mold cavity. After injection molding, the plastic will take away the silk screen pattern on the surface of the sheet and separate it from the sheet; IML is to place the transparent sheet with silk screen printing on the back into the mold cavity after molding. After injection molding, it is integrated with the plastic, and the silk screen part is sandwiched between the sheet and the plastic. The process of IMF, INS and IML is similar. The difference is that IMF injects the e
