MOBILE PHONE PROTECTION CASE FILM WITH TRANSPARENT PART AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to a mobile phone protection case film with a transparent part and a method for manufacturing the same, and specifically a method for manufacturing a protection case film inserted in a protection case cover hinged to one side of a protection case for receiving the back and the sides of a mobile phone so as to open or close the front of the mobile phone, includes the steps of: assembling a first die and a second die so as to form a cavity conforming with the shape of the protection case film; filling the cavity with a molten resin through a gate provided in one side of the cavity; compressing the molten resin filling the cavity by closely contacting the first die and the second die with each other; cooling or hardening the molten resin; removing the .molded product by separating the first die and the second die; and cutting off the gate from the molded product. Thus, the method can considerably reduce the processing time and cost compared to the conventional processing method using a numerically controlled processing machine, and minimize the flaw rate by eliminating the errors according to the skill of a worker so as to improve the reliability of the product.

1. A method for manufacturing a mobile phone protective case film, having a transparent part and inserted in a protective case cover, the protective case cover rotatably provided on a side surface of a protective case main body covering a rear surface and a side surface of the mobile phone, the method comprising the steps of combining a first mold and a second mold separate from the first mold to form a cavity corresponding to a shape of the protective case film; injecting a molten resin through a gate provided, at a side of the cavity to fill the cavity; bring the first mold and the second mold in tight contact with each other to compress the molten resin, filling the cavity; cooling or hardening the molten, resin; separating the first mold and the second mold and taking a formed article out; and cutting the gate away from the formed article, wherein the gate is provided as any one of a side gate formed at a side of the cavity, corresponding, to a side surface of the protective case film or one or more pin gates formed at a side of the cavity, corresponding to a plate surface of the protective case film 30 to prevent the protective case film from being bent by heat or pressure upon injection of the molten resin.
