Abstract

A mold coating agent test device includes a frame positioning portion and a connection positioning portion. The frame positioning portion positions a frame portion of a metal mold such that the frame portion of the metal mold is positioned at a predetermined position when the metal mold is placed on a metal block. The connection positioning portion 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 a force is connected is positioned at a predetermined position when the metal mold is placed on the metal block.

First claim

What is claimed is:

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.

2. The mold coating agent test device according to claim 1 , wherein:
the connecting portion is provided so as to project from an outer peripheral surface of the frame portion; and
the connection positioning portion includes a connection contact portion that extends along a shape of the connecting portion and restricts a relative rotation of the frame portion with respect to the metal block with the connection contact portion contacting the connecting portion.

3. The mold coating agent test device according to claim 1 , wherein the frame positioning portion and the connection positioning portion are included in a mold positioning member.

4. The mold coating agent test device according to claim 3 , further comprising a movement mechanism unit that allows the mold positioning member to move in a horizontal direction with respect to the metal block.

5. The mold coating agent test device according to claim 1 , further comprising a movement restricting unit that faces the surface of the metal block and restricts movement of the metal block toward the metal mold.

6. The mold coating agent test device according to claim 5 , wherein the movement restricting unit is composed of an upright portion and a horizontal portion each having a plate shape, and has an L-shape in a side view.
