Claims

[Scope of Claim for Utility Model Registration] A cylinder hopper is disposed at a material supply port for supplying molding material to a heating cylinder, a plunger is plunged into the cylinder hopper, and the molding material accommodated in the cylinder hopper is pushed by the plunger. In the injection device, the injection device is configured such that an engaging member whose engaging portion protrudes inward of the cylinder hopper in a set state is removably attached to the cylinder hopper, or the engaging member is configured to The cylinder hopper is provided so as to be movable between a position protruding inwardly and a position not protruding, and when the engaging member is in the set state, by raising the plunger, the plunger is engaged with the engaging portion of the engaging member. An injection device equipped with a plunger extrusion type hopper, characterized in that the cylinder hopper can be removed upward from the heating cylinder based on the situation.
