手段とを備えたことを特徴とする注入発泡型。 It is an injection foam mold that molds a foam molded product by injecting a foam molding material into a cavity and foaming and hardening it. A needle insertion portion that can be brought into close contact with the needle insertion portion without a gap by compressive force, a needle that is disposed corresponding to the needle insertion portion of the elastic body and has an opening connected to a compressed air supply source on the tip side, and the needle before molding. The injection foaming method is characterized in that it is equipped with a moving means that moves the elastic body backward so as to move the elastic body backward, and after molding, moves the elastic body forward so as to resist the compressive force of the elastic body and penetrate the needle insertion portion. Type.
