Claims

[Scope of Claim for Utility Model Registration] While detecting the position of the output shaft of the injection screw or a linear movement device that moves the injection screw in a straight line using a position detector, the injection screw is rotated to transfer the injection molding material into the injection cylinder. In an injection molding device that injects the injection molding material from the injection cylinder to the outside by pressing and driving the injection screw with a linear moving device after the injection molding material has been taken into the interior, the position detector includes: (a) the linear moving device 14A; (b) A potentiometer 12 with a sliding terminal attached to the output shaft or injection screw 17 of the potentiometer 14B; It includes a detector 13 that detects the voltage between the sliding terminal of the yometer 12 and one of the fixed terminals, and the output shaft of the linear moving devices 14A, 14B is detected by the voltage detected by the detector 13. An injection molding apparatus characterized in that the position of the injection screw 17 is detected.
