A method for forming patterns in injection molding comprises the steps of: forming a desired pattern on the surface of a metal model manufactured to be corresponded with a shape of a target product; electroforming on the surface on which the metal model pattern is formed; forming a mold core by exfoliating a metal layer formed by electroformation; forming an injection mold by using the mold core; and injection molding by using the injection mold and manufacturing injection molded products on which desired patterns are formed. By forming a desired pattern on the surface of the metal model and electroforming using the same in order to form the mold core, variously patterned injection molding products are manufactured in a simple process. More specifically, by forming the mold core using electroformation and injecting the same into a mold structure in order to form the injection mold, the injection mold capable of making desired patterns in a simple method can be formed. |
