摘要： The invention relates to a device and method for detecting a force on an injection moulding machine for processing plastic materials. According to said invention, a first element (100) interacting with a mechanical drive and movable at least indirectly thereby in a direction of movement (x) is displaced during said displacement with respect to a second element (200) positioned near the first element (100) or oppositely thereto. A force measuring device (D) is used for determining the force applied on the first (100) and/or second (200) element by the actuation of the injection moulding machine produced by the relative displacement thereof between the first (100) and second (200) elements. A hydraulic chamber whose size is modifiable during the relative displacement associated with a change in pressure of a fluid medium in said hydraulic chamber is firmed between the first (100) and second (200) elements, wherein said change in pressure forms an input signal for adjusting the force or pressure and a pressure-relief valve (30) is used for bypassing the hydraulic medium to a hydraulic medium container (35), when the predetermined or predeterminable presser is exceeded in the hydraulic chamber (10), thereby making it possible to obtain a device and method for detecting a force on an injection moulding machine which makes it possible to determine said force in a favourable alternative manner and simultaneously ensure an overload protection.

摘要： The present invention is a force detecting controlling device for a screw of an injection molding machine, which utilities a load cell as a force sensor for injection, holding pressure and back pressure. The load cell arranged on a rear fixed plate directly detects a force applied onto a ball screw nut. Because the ball screw nut is fastened on the load cell, and the load cell is fixed on the rear fixed plate, the force on a ball screw is directly transmitted to the ball screw nut. Therefore, a total value of the force on the ball screw produced by back pressure and friction among mechanical parts are equal to a force value of the ball screw nut applying onto the load cell. The injection force detected via the load cell for an instant response reaches a close loop control and procedures of holding pressure and back pressure are specifically controlled as well.

摘要： The electric injection molding machine comprises a sensor 21, servo motor 15, a motor 23 and a controller 30 and, in a plasticizing process in which the motor 23 is rotated, the controller 30 performs control by repeating a first process in which the rotation of the servo motor 15 is controlled by a first retreating speed command value 33 to make the screw 13 retreat at a low speed when a screw backpressure signal is smaller than a backpressure set value 31 and a second process in which the rotation of the servo motor 15 is controlled by a second retreating speed command value 34 to make the screw 13 retreat at a high speed when the screw backpressure signal is larger than the backpressure set value 31.

摘要： An injection unit of injection machine operates to drive a time-belt pulley associated with a thrust bearing, a bevel ball-bearing, and a bearing nut to make a ball-bearing guiding screw move swiftly to in turn drive a movable plate to perform an injection stroke. The injection pressure transmitted backwards by a plasticized auger is sensed by a load bearer equipped with a pressure sensor something like a strain gauge. After an injection stroke, by means of another time-belt pulley and a shaft coupling, the plasticized auger is restored to its original position and ready for a next cyclic motion. During the cyclic injection process, the load bearer is in charge of sensing the pressure change and reckoning the back pressure in order to obtain the best injection quality.
