<p>PURPOSE:To secure a gap between the opening part of a crucible and the sprue of a mold even at the time of directing a chamber in the reverse standing state, to quickly act gas pressure at the time of introducing the gas to molten metal positioned in the space, to quickly and precisely cast a metal cast product and to smoothly execute inserting/removing operation of the crucible to/form a crucible supporting means. CONSTITUTION:An opening part 28 for inserting the opening part 21a of the crucible 21 is arranged in a mold supporting plate 27 and also, a stopper 29 for securing the gap between the opening part 21a of the crucible 21 and the sprue 26a of the mold 26 by engaging with the opening part of the crucible 21 is arranged in the condition of being possible to engage/disengage. Further, the gas flowing passage 30 communicating the gap with a space at the outer periphery of the mold is formed in the mold supporting plate 27.</p> |
