The molding apparatus includes a male mold fixing base, a first male mold, a second male mold, a female mold fixing base, a first female mold, a second female mold, a central axle and a middle plate. The first female mold forms a first cavity with any one of the male molds, and the second female mold forms a second cavity with any one of the male molds, and a glue injection is performed in the first cavity and the second cavity by a first glue injection unit and a second glue injection unit respectively. The first female mold and the second female mold are coupled to the female mold fixing base, and the first male mold is installed above a first male mold insert fixing base of the male mold fixing base, and the second male mold is installed above a second male mold insert fixing base of the male mold fixing base, and both first male mold and second male mold are coupled to the middle plate, and the first male mold is rotatably installed at the top of the second male mold insert fixing base and the second male mold is rotatably installed at the top of the first male mold insert fixing base through the central axle connected to the middle plate. Therefore, a dual color glue injection can be completed for the dual color mold without replacing the molding apparatus. | 06-03-2010 |
