Abstract
A core molding method is a method of molding a core using a metal mold that is pressure-fed with mulled sand, and includes heating the metal mold such that the temperature of the metal mold reaches a temperature higher than a predetermined baking temperature, pressure-feeding the heated metal mold with the mulled sand, holding the temperature of the metal mold having been pressure-fed with the mulled sand at the baking temperature, and removing the core from the metal mold after the holding.
