The mold r of the known device has a recess u for inserting a fork of a two-row forklift at the bottom, but the edge v has the same shape in every part (cross section). As a result, the side surface of the solidified ingot is a smooth surface, which is inconvenient to handle. Also, since the ingot is taken out by inverting the mold,
The take-out device s is a mold tumbling take-out device, but since the ingot does not come out even when the mold is tumbled, the ingot is swung vigorously with a certain amount of rotational force, and the ingot is pulled out using the inertia. Not only was there a surprisingly loud vibration and loud noise, but there was also the problem that the factory equipment was damaged by the vibration. Therefore, the first problem is solved as a mold with hanging hardware so that a concave portion can be formed on the peripheral surface of the ingot so that the concave portion can be held by a jig. However, since the use of the hanging hardware causes another problem of how to remove the hanging hardware from the die, the present invention provides
