PROBLEM TO BE SOLVED: To prevent opening of a mouth die at the press molding of a parison in the molding of glass products by a press -and- blow molding machine. SOLUTION: The receiver plate on which a mouth die is placed at the press molding of the parison at a parison molding part of the press -and- blow molding machine for the molding of glass products, has a hole in the center of the plate body through which a plunger passes and is provided with build-up parts erected on the outer peripheral part of the front face side to prevent opening of the mouth die. The build-up parts abut to the outer peripheral part of the mouth die to constrain the mouth die so as to prevent the mouth die from opening. Also the mouth die (and a crude mold) is positioned by fitting of the mouth die to the build-up part, the center of the plunger coincides with those of the mouth die and the crude mold, so that the parison with high accuracy can be molded.
