Abstract

The present invention relates to a casting mold for a metal sheet by drawing molten metal into a mold cavity and cooling the molten metal, and the casting mold according to the present invention includes: a support portion at an upper side on which molten metal is disposed or a solid metal is placed and melted; a mold cavity at a lower side in which the metal sheet is formed as the molten metal is drawn from the support portion while filling the mold cavity and cooled; and a passageway through which the molten metal is drawn into the mold cavity from the support portion, in which the mold cavity includes a first surface at the upper side which communicates with the passageway, and a second surface at the lower side which faces the first surface, a plurality of suction portions for drawing the molten metal are formed in the second surface and extended downward from the second surface, the suction portions are connected to a vacuum source and configured to draw the molten metal by suctioning air from the mold cavity, and a blocking member, which is in contact with the second surface or the suction portions to prevent a leakage of the molten metal and allow an air flow, is disposed on the suction portions in the mold cavity.
