Abstract
PURPOSE: To plasticize resin homogeneously without counter flow of resin, retreat of the screw, etc. in times of injection of resin by a method wherein a cylinder made up of a special structure and a screw through which a plunger is penetrated are provided and the screw or the like can rotate, move independently.
CONSTITUTION: The cylinder 1 is heated, the screw 5 is rotated, raw material of resin is inserted from an inserting hole 15 and the resin is platicized in the cylinder 1 and sent forward. At this time, the screw 5 is retreated by the back pressure and a gap 16 is formed between the front part 6 of the screw 5 and the conical surface 4 of the cover 2 of the cylinder 1. The plunger 8 is retreated by the resin pressure of the front part of the screw 5 and the resin is charged in a measuring cylinder part 17 produced thus. After measurement is finished, the screw 5 stops its rotation, the screw 5 continues to be advanced by the cylinder 9 and is fitted and attached tightly to the front part 6 and the conical surface 4 of the cover 2. Then, the plunger 8 is advanced by the cylinder 10 and injects the resin.
EFFECT: Density of resin is released from deviation and burs are prevented from occurring.
