CORE-BACK TYPE FOAMED RESIN MOLDING MOLD, CORE-BACK TYPE FOAMED RESIN MOLDING METHOD, AND CONTAINER-LIKE FOAMED MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a core-back type foamed resin molding mold which allows a bead to be provided on the distal end face of a side wall of a container-like foamed molding while suppressing the manufacturing cost of the mold, a core-back type foamed resin molding method, and the container-like foamed molding.;SOLUTION: The core-back type foamed resin molding mold 21 includes a thickening molding part 24B molding a distal end edge (distal end thick part 53) of a side wall 52, and a side wall body molding part 24A molding a part (side wall body part 54) other than the distal end edge of the side wall 52, in a cavity 24. When core-backing the molding mold 21 by filling molten resin in the cavity 24, the end face of the distal end thick part 53 molded at the thickening molding part 24B is raised to form the bead 55. That is, the bead 55 can be formed even without forming the groove for the bead in the molding mold 21, thus suppressing the manufacturing cost of the molding mold 21.;COPYRIGHT: (C)2011,JPO&INPIT
