性、品質精度、信頼性が著しく向上されている。As described above, according to the present invention, in the automatic powder molding machine, the raw material powder filled in the molding hole of the die incorporated in the table is continuously fed into the molding hole by the upper and lower die punches. The molding height of each pressure-molded body is detected by the height with the table at the bottom dead center of the sensor that moves up and down together with the upper die punch, and this detection signal is calculated by the controller and each molding The measured height signal of the body and the measured height signal are compared with the standard height tolerance range of the molded body and output as a molding stop signal when there is an abnormality, and this measured height signal is displayed as the measured height of each molded body on the display. When it is displayed and the measured height of the molded body is abnormal, the pressure molding is automatically stopped, the molding precision is automatically grasped with high accuracy for each pressure molding of each molded body, and the eddy current type mutation For detection by sensor Detection accuracy and its reliability are further improved, and defective products can be selected and readjusted at any time, making quality control significantly easier, and labor-saving as well as productivity, quality accuracy, and reliability are significantly improved. ing.
