Feeding mechanism for injection-molding machine

摘要

A feeding mechanism for injection-molding machine includes an injection machine frame, which is provided at a middle section with a feeding pipe defining a chamber for receiving heated and softened plastic material therein, such that the received plastic material for injection molding could be pushed forward under an axial pressure from a rear section of the chamber, and in front of the chamber with an injection channel, such that the plastic material in the chamber for injection is injected via a front open end of the injection channel into a mold. The feeding mechanism is characterized in that the feeding pipe is provided at an upper side with a plurality of feeding inlets, so that a plurality of material tanks having differently colored plastic materials stored therein are separately connected thereto for forming an injection-molded product containing different colors through only one injection.
