The present invention relates to a mold for manufacturing a vehicle engine piston having a structure capable of discharging the gas to the outside is generated in the forming space during casting. As a mold used when molding the piston for a vehicle engine as a gravity casting method, the lower mold (3), the cylinder of the piston for molding the upper mold (1), the space in the lower portion and bottom portion of the piston for forming the piston head part It is composed of two side mold (5) for forming a part; It said upper mold (1) with a first vent member of a porous metal (7) are combined into an uneven doedoe expression; And one side of the first vent member 7 is exposed to the molding space of the mold; The other side being exposed to the gas holes 27 to be communicated with the outside air in the first vent member (7); Gas discharged from the molding space during the molding is characterized in that it is discharged to the outside through the first vent member (7).
