1. A mold coating agent test device in which a performance of a mold coating agent is tested by applying the mold coating agent to a surface of a metal block, placing a metal mold having a tubular shape on the metal block such that the metal block closes one end portion of the metal mold, and applying a pulling force or a pushing force to the metal mold such that the metal mold is separated from the metal block after a molten metal is poured into the metal mold and solidified, the mold coating agent test device comprising:
a frame positioning portion that positions a frame portion of the metal mold such that the frame portion is positioned at a predetermined position when the metal mold is placed on the metal block; and
a connection positioning portion that positions a connecting portion such that the connecting portion that is a portion provided in the frame portion and to which a drive unit that applies the force is connected is positioned at a predetermined position when the metal mold is placed on the metal block,
wherein the frame positioning portion includes a frame contact portion that is in contact with a curved part of an entire circumference of an outer peripheral surface of the frame portion from an outside of the frame portion and that has a shape that extends along a shape of the frame portion.
