PROBLEM TO BE SOLVED: To provide a load cell attaching structure of an injection molding machine which makes attaching and detaching of load cells to/from an injection apparatus easier and is able to detect resin pressure applied to a screw accurately.SOLUTION: An injection apparatus 3 comprises: a heating cylinder attaching bracket 13 holding a heating cylinder 14; plural nut members 18 fixed at the heating cylinder attaching bracket 13; screw axes 38 screwed with each nut member 18; a linearly moving body 31 holding the screw axes 38 so as to be rotatable; a screw 15 inserted into the heating cylinder 14 so as to be rotatable and movable backward and forward; a rotation coupling body 34 coupling the screw 15 with the linearly moving body 31; a measurement electric servo motor 36 driving the screw 15 rotationally; an injection electric servo motor 40 driving the screw axes 38 rotationally; and load cells 19 detecting the resin pressure applied to the screw 15. The load cells 19 are positioned between the heating cylinder attaching bracket 13 and at least one of the plural nut members 18. |
