Abstract
PURPOSE: To perform degassing and prevent the melt from discharging with certainty, by providing a valve in a degassing groove in a direction different from an axial direction of degassing and further providing a roundabout passage which goes round the side of the valve from the degassing groove.
CONSTITUTION: When a melt flows into a cavity 7, gas passes through a roundabout passage 19 and is discharged outside via a through hole 4a and a gas discharging passage 4b. After that, when the intruding melt enters into a valve chamber 12 and collides with an end face of the valve 13, an engaging mechanism 15 is released and the valve 13 moves leftward pulled by an elastic object 16. Resulting from this an opening part of the roundabout passage 19 to the valve chamber 12 is blocked by a peripheral face of the valve 13 and a connecting state among the roundabout passage 19, the through hole 4a and the gas passage 4b is shut. Thus, degassing from the cavity and prevention of melt discharging can be performed certainly.
