To provide a die-casting line wherein individual management of each mold can be reliably performed even after sand is removed, by performing sand removal for each mold in a mold after a molten metal is supplied thereto.

A die-casting line includes: a molding board carriage for conveying a mold; a mold conveying receptacle which is provided on the molding board carriage, stores therein one mold and has a sand removing grid provided at a bottom of the mold conveying receptacle; a sand dropping device for dropping the cast sand from the mold conveying receptacle by vibrating the mold conveying receptacle; and a transfer device which moves the mold conveying receptacle storing the mold, to the sand removing device and transfers the mold conveying receptacle wherein sand dropping is completed, onto the molding board carriage.
