A casting device in which refrigerant is pressure-fed to a cooling passage formed in a die, leakage of refrigerant in the die can be reliably detected in a short time without a significant modification applied to the conventional device. A casting device includes a pressure-feed device that pressure-feeds refrigerant to a cooling passage formed in a die, and a release agent coating applicator that applies a release agent to the die, and further includes a unit that mixes a fluorescent agent into the refrigerant (fluorescent agent tank), a unit that irradiates the die surface of the die with black light while the refrigerant containing the fluorescent agent mixed therein is pressure-fed to the die, and an imaging device that captures an image of the die surface. The imaging device is integrally assembled with the release agent coating applicator.

A powder-containing oil-based lubricant for die contains 60 to 99% by mass of an oil-based lubricant consisting of oil, 0.3 to 30% by mass of a solubilizing agent, 0.3 to 15% by mass of an inorganic powder and 7.5% by mass or less of water, the lubricant being electrostatically applied to a die. The powder-containing oil-based lubricant may be applied to a die by electrostatic spraying. The electrostatic spray apparatus includes a device that imparts static electricity to the powder-containing oil-based lubricant and an electrostatic spray gun installed on a multi-axis robot.
