Abstract
An injection blow molding device in which a lip mold is formed in different shapes for an injection mold and a blow mold. Mold clamping surfaces corresponding to the different shapes are formed on the injection mold and the blow mold, respectively, to prevent an air leakage from the blow mold. An upper portion of an outside surface of the lip mold which contacts the mold is formed in a tapered surface whereas a lower end portion of the outside surface is formed in a vertical surface. The upper portion and the lower portion of a surface contacting the lip mold, of each of the injection mold and the blow mold are formed respectively in a tapered surface and a vertical surface that correspond to the tapered surface and the vertical surface of the outside surface of the lip mold. Clamping the lip mold in the injection mold is performed at the tapered surface of the upper portion and clamping the lip mold in the blow mold is performed at the vertical surface of the lower end portion.
