Abstract
In order to eject resin leaked from an injection chamber ( ) toward the shaft side of an injection plunger ( ) away from an injection cylinder ( ), a plunger-type injection molding machine injection device is equipped with an ejection guide ( ) at the rear edge of an injection cylinder which is thermally isolated from the injection cylinder main body. A band heater ( ), which heats the ejection guide, is controlled independently of the band heater ( ) which heats the injection cylinder. One embodiment of this injection guide ( ) causes the ejected resin to fall from the ejection opening ( h) while retaining its molten state. In another embodiment, the ejection guide ( ) has ejection channels ( f) which cause the resin to harden and be ejected in a fine strand state.
