PURPOSE: A hot forging mold in which a coolant discharging path is provided to select a structure in which the coolant is efficiently discharged in a forging process, thereby maintaining the temperature of the mold and preventing damages by using the coolant without an extra liquid release agent. CONSTITUTION: A hot forging mold in which a coolant discharging path includes an upper mold(110) and a lower mold(210). Numbers of coolant discharging path(D, D1) pass through perpendicularly and are formed on each of the upper mold(110) and lower mold(210). An upper pad(120) and a lower pad(220) are formed on the upper and lower portions of the upper mold(110) and lower mold(210). A connection path(C), which is connected to the coolant discharging path(D, D1), is horizontally formed on the upper pad(120) and lower pad(220). The inlet of the coolant discharging path(D, D1) is formed on the edge of the upper pad(120) and lower pad(220). The upper mold(110) comprises a cylindrical upper insert mold(114) and a ring-shaped upper mold body(112) in which a coupling hole(112a) is formed for coupling the upper insert mold(114) and the coolant discharging path(D, D1) is formed. A concave portion(114a) for discharging the coolant is formed on the outer periphery of the upper insert mold(114).
