Abstract: A molding machine includes an injection device to inject a molding material into a mold and a control device to control the injection device. The injection device includes a heating cylinder filled with the molding material and a screw moving forward/backward inside the cylinder to inject the molding material, and can move forward/backward between a communication orientation where a distal end of the cylinder communicates with the clamped mold and a separation orientation where the distal end separates from the mold and can pivot on a pivot shaft between the separation orientation not allowing insertion/removal of the screw and a pivot orientation allowing the insertion/removal. The molding machine further includes a sensor to detect these orientations. The control device determines that the screw has been replaced by the sensor detecting that the injection device pivots from the separation orientation to the pivot orientation and returns to the separation orientation.
