Abstract
PURPOSE: To provide the titled device which is simple in mechanism and free from reduction of injection amount and injection speed by a method wherein a dwelling chamber is provided at a tip part of a heating cylinder head part, a dwelling plunger fitted into the dwelling chamber is arranged concentrically with the chamber and it is operated by a hydraulic cylinder for dwelling.
CONSTITUTION: The heating cylinder head 12 is rigidly fitted to the tip end of the heating cylinder 11, the dwelling chamber 14 is provided at a place adjacent to a nozzle hole 13, and the dwelling plunger 15 fitted into the chamber 14 is arranged concentrically with the chamber 14. The hydraulic cylinder for dwelling 16 is connected to an end part of the plunger 15 through a connecting arm 18. A raw resin is plasticized by rotating a plasticizing screw 22, is fed to the dwelling chamber 14 through a screw check 24 and a passage 21 for the resin, and is injected and filled into a cavity through the nozzle hole 13. After the filling operation is completed, the plunger 15 is advanced and fitted into the dwelling chamber 14 by the hydraulic cylinder 16 to pressurize the resin in the cavity.
