PURPOSE:To prevent the ununiformity of cooling accompanied with the fluctuation of thickness of a formed body and the roughening of the surface of the formed body by a method wherein laminal cooling elements are provided along the formed surface on the surface layer part of the formed surface of a die adjacent to the thick zone of the formed body. CONSTITUTION:A forming surface 13 of a die corresponding to the mouth of a vessel is composed of die inserts 5a, 5b for cooling the opening in which laminal cooling 4a, 4b provided curvedly along this forming surface are built respectively. Die inserts 8a, 8b for cooling the bottom part to which elements 7a, 7b have been attached previously so that a pair of laminal cooling elements 7a, 7b are arranged along this formed surface are joined with the lower part of the formed surface 6 of the die corresponding to the bottom part of the vessel. The laminal cooling element applies Peltier effect. |
