ABSTRACT:
A structure supporting a hopper with granulate raw material on the injection unit of an injection molding machine, the structure featuring a conical lower section on the hopper with an adjoining hopper extension in the form of a cylindrical wall and a radial flange, the hopper extension being clamped between a hopper base and a clamping bell with a conical cavity. On the carrier bridge of the injection unit is mounted a horizontal guide plate which engages a guide groove in a flange of the hopper base, for transverse mobility of the hopper between the charge chute of the plastification cylinder and a discharge opening. A clamping lever serves to secure the hopper on the guide plate.
