A die casting mold for forming an inclined hole in a cylinder block is provided to enable cylinder blocks to be mass-produced by high pressure casting and allow the inclined hole to be integrally formed during casting by installing a core pin for forming the inclined hole at a portion on an inner part of the die casting mold, thereby preventing interference of the core pin with a sleeve used as an injecting path of molten metal. In a die casting mold comprising a fixed mold and a movable mold for high pressure casting of a cylinder block, and a sleeve(14) for injecting molten metal into the molds, a die casting mold for forming an inclined hole in the cylinder block is characterized in that: a moving space part(16) is formed in the fixed mold, the moving space part comprising a first space part(16a) formed above the sleeve to avoid the interference with the sleeve and a second space part(16b) formed at left and right sides of the sleeve; an inclined hole-forming device is installed in the moving space part to form an inclined flow path in the cylinder block during casting; and the inclined hole-forming device comprises a movable member(18) movably installed in the first space part, a core pin(20) installed on the movable member to form the flow path in the cylinder block, and actuators installed in the second space part to reciprocate the movable member.
