Abstract:
A mold for expanded moldings, comprising:a vessel-shaped lower mold forming a cavity and having a base, a bottom section for receiving a liquid for expansion, a protrusion formed on the base and located in the bottom section to be disposed in the liquid, and an upper section located above the bottom section for allowing the liquid retained in the lower section to expand in an expanded molding;an upper mold for covering said lower mold above the upper section and having a bottom surface; anda partition wall disposed protrusively from the bottom surface of said upper mold so that an inside of said mold is divided into a plurality of small cavities by said partition wall, said partition wall extending through the upper section into the bottom section to form a clearance between a bottom end of the partition wall and the base of the lower mold so that the clearance serves a function of equally maintaining a level of the liquid poured in each of the small cavities and of unifying foaming pressure in each of the small cavities.
