PROBLEM TO BE SOLVED: To solve the following problem, that a spray nozzle of an internal mixing/atomizing type using three kinds of fluid of a mold cooling liquid, a liquid releasing agent and compressed air has a complicated structure in a unclear state where an oil type releasing agent is used. SOLUTION: When using a water-soluble releasing agent, the structure of a nozzle is employed in which only one liquid of the releasing agent is caused to pass through a spool without using compressed air, the releasing agent is accelerated by the increase of eddy currents and a nozzle, and is fined, atomized and jetted at a speed of≥10 times of the speed at spool passage, and therefore the structure of the nozzle is simplified into a connector, a spool, the nozzle and an air jacket. When using the oily releasing agent having high viscosity, the spray nozzle device for water-soluble releasing agent and also for the oily releasing agent is employed which uses compressed air as an assistant, includes an air jacket and the nozzle provided with a fitting part and an compressed air chamber, and can perform application by refining atomization without performing inner mixing.
