Abstract

Provided is a low-pressure casting device whereby maintenance of an intermediate stoke can be facilitated. The present invention provides a low-pressure casting device having: a crucible inside which molten metal is stored; a stoke body which is inserted in the crucible and which supplies molten metal into a cavity of a die; and an intermediate stoke for connecting a sprue of the die and the stoke body; wherein the intermediate stoke has an inner, an intermediate stoke body for retaining the inner in the inside thereof, and a cover for covering the outside of the intermediate stoke body via a heat insulating part, a heater accommodating groove is formed in a side surface of the intermediate stoke body, and a heater is attached to the heater accommodating groove.
