Title: Injection molding machine
Inventor: SATO HIROYUKI
IPC: B29C45/58
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To make it possible to suppress the molding loss of a resin material to small when a resin molding has a small capacity by making it possible to approach the extrusion position of the material by a plunger as near to the cavity of a mold as possible in a preplasticating injection molding machine having the plunger in an injection cylinder. SOLUTION: A primary large-diameter plunger 7 is inserted into an injection cylinder 2 and a secondary small-diameter plunger 8 is inserted into the axial central part of the plunger 7 so as to make it possible to be telescopically movable. The resin material extruded from the cylinder 2 by the forward movement of the plunger 7 and remained in the nozzle hole 3a of an injection nozzle 3 is extracted by inserting the plunger 8 at its end into the hole 3a by advancing the plunger 8.
