ABSTRACT:
An elastic forming die with an aperture section through which a molding material is charged, including a main mold section in membrane form which acts as a female mold for the molded product; a conical section in membrane form which is connected to the aperture section and expands outwardly in the shape of a cone; and an aperture roll section provided at the outer peripheral edge of the cone section, and a method for manufacturing this elastic forming die. Because the elastic forming die is provided with the conical section which is connected to the aperture section and expands outwardly, the release of the molded product from the mold is extremely easy and the elastic forming die can be used to manufacture molded products such as chocolate, jelly, and the like. The molding method using the elastic forming die features the release of the molded product utilizing said cone section.
