Claims

[Scope of utility model registration request]

An on-off valve 9 attached to the end of a gas vent path 6 led from the cavity 5 of the mold 1, a valve drive mechanism 12 for opening and closing the on-off valve, and a valve drive mechanism 12 disposed in the middle of the gas vent path and connected to the cavity. It has a detection rod 10 that detects the filled conductive molten metal by contact with the molten metal to be injected, and a flip-flop circuit 11b,
The electromagnetic valve 12a and the valve actuation cylinder 12 of the valve drive mechanism are electrically connected to the detection rod, and actuated when the molten metal to be injected momentarily contacts the detection rod.
d through an electric circuit so that the on-off valve is closed, and the solenoid valve and the valve actuating cylinder are activated by a reset signal sent from the electric circuit by removing burrs in the gas vent passage. 1. A degassing device for an injection molding machine, comprising an electronic circuit 11 that operates via an electric circuit so that an on-off valve is opened.
