Mold for molding hollow bricks by means of a press, comprises at least one punch affixed to the movable crosspiece of the press. A die is provided with at least one cavity for containing the material to be pressed and is engageable by the punch during the pressing step. At least one counterpunch constitutes the bottom of the die cavity and is movable between a position where it rests on the press base and a position where it ejects the molded brick. The die is supported in a yielding manner vertically with respect to the press base. Rod-like elements adapted for forming the holes through the bricks are rigid with the die. The rod-like elements penetrate the counterpunch and the cavity and are further adapted for inserting themselves in respective seats in the punches during the pressing step.
