Abstract
The invention provides an oil type release agent die casting containing 70 to 98 parts by weight of a solvent having a specified flash point, 1 to 10 parts by weight of mineral oils and/or synthetic oils having a high viscosity, 15 parts by weight or less of a silicone oil, and 1 to 5 parts by weight of additives having a lubricating function, wherein the flash point of the agent is in the range of 70 to 170° C., and dynamic viscosity of the agent is 2 to 30 mm2/s or higher at 40° C., and a method for setting a mixing ratio of the solvent, a casting method, and a spraying unit for the case of using the release agent.
