A separable nozzle is provided to increase durability by using high-hardness materials and to precisely form nozzle holes by dividing a nozzle body into two parts and using a CNC(Computer Numerical Control) machine. The separable nozzle for producing a mold is composed of a nozzle body(11) formed at predetermined thickness in the longitudinal direction; a plurality of nozzle holes(15) bored through one surface of the nozzle body in the predetermined size and formed in a line; and a charging standby part(14) recessed on the opposite side where the nozzle holes are formed, at the nozzle body. The nozzle body is split into left and right parts along the center of the nozzle hole. The left and right nozzle bodies are recessed toward the nozzle hole on the opposite side where the nozzle holes are formed and provided with plural nozzle combining grooves(12). A staple-shaped combining block is fitted into the nozzle combining grooves to join the split nozzle bodies.
