Abstract: A injection molding machine includes a power device including a movable plate, a primary motorized cylinder having a primary threaded rod screwed through the movable plate, a secondary motorized cylinder having a secondary threaded rod screwed through the movable plate, a first starter mounted on the primary motorized cylinder and connected with a controller, and a second starter mounted on the secondary motorized cylinder and connected with the controller. The second starter contains a bias factor command and a preset output command. Thus, the normal torque output of the secondary motorized cylinder is close to that of the primary motorized cylinder by control of the bias factor command, and the preset output command limits and prevents the normal torque output of the secondary motorized cylinder from being greater than that of the primary motorized cylinder.

Abstract: {Problem} The exact method with small time-lag of detecting screw back pressure for controlling the screw back pressure in the plasticizing process of an electric-motor driven injection molding machine without using a pressure detector has been asked for because the pressure detector is very expensive, necessitates troublesome works for mounting, an electric protection against noise and the works for zero-point and span adjustings and causes a complicate mechanical structure.{Solution} The present invention uses a high-gain observer which contains the discrete-time arithmetic expressions derived from a mathematical model of a plasticizing mechanism in an electric-motor driven injection molding machine consisting of a state equation and an output equation and outputs an estimate of screw back pressure, which is one of the state variables of the above state equation, by using a screw backward velocity signal, a motor current demand signal applied to a servomotor for injection or actual motor current signal and a screw revolution speed signal as inputs. The high-gain observer obtains the exact screw back pressure estimate with very small time-lag without using a pressure detector. Thus the estimate of screw back pressure fed by the high-gain observer can be adopted as a feedback signal of actual screw back pressure for controlling the screw back pressure in the plasticizing process.

Abstract: Intended is to provide a molding machine using a built-in type motor as an injecting electric motor. In this molding machine, a mounting structure for such a transmission mechanism from a rotational motion to a linear motion, as changes the rotation of the built-in motor into the linear motion thereby to transmit the linear motion to an injecting member, is simplified to improve the assembling workability. For this improvement, a sleeve is fixed in the rotor of the built-in type motor. In the hollow portion of the sleeve, a screw shaft or the rotating portion of a ball screw mechanism and the sleeve are connected and fixed by a connecting member. A nut member or the straight portion of the ball screw mechanism is fixed on a member for performing straight motions together with the injecting member.
