Abstract
PURPOSE:To mold a product having a closure film by an injection molding method, many in a taking number and high in a molding speed, by forming a cup shape becoming the closure film in the first closure film forming process using a metal film, and performing the injection molding of a resin in the second process to unify the closure film with the synthetic resin. CONSTITUTION:A mold is constituted of a movable mold (core side) having the same molds connected to two surfaces thereof and a fixed mold having the shape of a molded product (cavity side) and a metal foil punching/shape imparting mechanism in opposed relation to said two surfaces, and the movable mold has a structure rotatable by 180 deg. around the center thereof. When the mold is opened and the molded product on the molding side is removed, the movable mold is rotated by 180 deg. around the center of the mold and matched with the fixed mold to enter a clamp process. At this time, the mold enters a shape imparting process for forming a closure film from a newly supplied aluminum foil on a non-molding side. In the clamp process, the closure film is set to the mold by a core pin so as to be positioned in the vicinity of the mouth part thereof, and a molten synthetic resin is injected in the mold.
