Abstract: Disclosed is a binder supply apparatus for supplying a liquid binder to foundry sand. The binder supply apparatus comprises: a reservoir tank for reserving the binder therein; a first pump for supplying the binder to the reservoir tank; a temperature adjusting device for adjusting the temperature of the binder in the reservoir tank to a given temperature; a second pump for circulating the binder such that the binder is discharged from the reservoir tank to a circulation passage and then re-suppled to the reservoir tank; a flowmeter for measuring the flow rate of the binder flowing through the circulation passage; and a binder ejection port for ejecting the binder.

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.
