PROBLEM TO BE SOLVED: To provide a foaming mold capable of easily manufacturing foamed resin molded blocks different in physical properties such as an expansion ratio or the like using a fundamentally same mold. SOLUTION: In a mold comprising a pair of a male mold and a female mold used for the foam molding of pre-foamed resin particles, an opening rate adjusting auxiliary plate 50 is attached to a molding surface 30. The existing opening rate of the molding surface can be changed by adjusting the opening rate of the opening rate adjusting auxiliary plate 50. Molded blocks having various physical properties can be manufactured only by changing the opening rate adjusting auxiliary plate 50 while using the mold in common. COPYRIGHT: (C)2004,JPO&NCIPI
