Abstract
A mold for expanded moldings capable of efficiently forming small-sized products in high-yield includes a vessel-shaped lower mold and an upper mold covering the lower mold. A partition wall is disposed protrusively from the bottom surface of the upper mold, and the partition wall divides the inside of the mold into a plurality of small cavities. A clearance of approximately 1 to 10 mm is defined between the partition wall and the base of the lower mold.
