PRELIMINARILY PLASTICIZING TYPE INJECTION UNIT

摘要

PROBLEM TO BE SOLVED: To realize a compact unit structure in a preliminarily plasticizing type injection unit equipped with a plasticization cylinder and an injection cylinder. SOLUTION: A screw device 14 equipped with a plasticization cylinder 10 is superimposed vertically above on a plunger device 20 supported freely movably in an approaching/separating direction to or from a clamping device by being equipped with an injection cylinder 16. The plasticization cylinder 10 of the screw device 14 is supported parallel to the injection cylinder 16 of the plunger device 20 and mutually movably in an axial direction.
