摘要

[Problem] The objective of the present invention is to achieve high speed molding of compacts and molding of compacts of arbitrary shapes by providing a mold lubricating oil that has excellent quick-drying properties and can form an even, uniform oil film with the coating of a small amount thereof, a spray coating device, and a compact molding apparatus. [Solution] The present invention pertains to a mold lubricating oil that includes a C_7–18 hydrocarbon solvent and an oiliness agent or an extreme pressure agent. The present invention is preferably a mold lubricating oil in which the content of the hydrocarbon solvent is 50–98 mass%.
