    Abstract: An injection mold for a multi insert container is provided, which includes a plurality of cavities, formed in order between a fixed mold and a movable mold that constitute an injection mold, for performing an insert molding of the multi insert container by stages, wherein an insert injection molding is performed simultaneously with a successive supply of molded products to the respective cavities. According to the injection mold, since a multi insert molding is performed through movement of the molded products by stages in the single mold, the workability is improved in comparison to a conventional insert molding method that uses a plurality of molds, and the molding conditions of the molded products are kept uniform to achieve a good quality of the molded products.
