などの危険がないなどの優れた効果を奏する。As is apparent from the above description, according to the present invention, it is possible to easily and surely check whether there is a large gap between molds or between a mold and a stalk. Therefore, when performing low pressure casting, unlike the conventional equipment of this kind, there is no leakage of molten metal from those gaps, as a result, cooling of molten metal, removal of cooled metal, It has excellent effects such as the re-heating of the mold or the coating of the mold to stop the operation of the equipment for 4 to 8 hours and the risk of causing a major disaster.
