Abstract

PURPOSE:To detect the pushing force at a nozzle to a mold by the change of electric current value of a servomotor by moving the nozzle using a transmission gear that converts the rotation of the servomotor to a straight motion. CONSTITUTION:When the servomotor 17 is driven, the lead screw 12 is turned through the gears 18, 19, the nut 6 is moved, the injection device 1 is guided by the rail 11 to be moved to the arrow A. As soon as the nozzle 5 touches the injection port 22, the location is detected by the detector 16, the servomotor 17 is stopped and molding material is injected by the operation of the servomotor 17.
