摘要： A straight-acting mold clamping device of an injection molding machine driven by two motors, which effects mold closure or opening at a high speed and which produces a required mold clamping force without using any large-capacity motor. The mold clamping device has a ball screw (6) that screws into a ball nut (7) which moves together with a movable platen (1) as a unitary structure. The ball screw is coupled to a servo motor (10) via transmission mechanisms (8, 9, 11, 17), and is further coupled to an induction motor (12) via a transmission mechanism, a reduction gear (14) and a clutch (15). There is further provided a numerical controller (20) which controls the servo motor, the induction motor and the clutch. The moving platen that is driven by the servo motor reaches a mold touch position at a high speed, and is then driven with a large force by both the servo motor and the induction motor until it reaches a position where a predetermined force is generated to clamp the mold. Further, at a moment when the moving platen has reached the position where the predetermined mold clamping fforce is generated, the induction motor is controlled by a brake device (13), whereby the moving platen is locked at that position to generate a predetermined clamping force.

摘要： A motor-driven straight-acting mold clamping system, which is capable of closing or opening a mold at a high speed without using any large motor and generating a required mold clamping force. When the mold is opened or closed, a ball screw (8) engaged with a ball nut (7) which can be moved unitarily with a moving platen (1) is rotated at a high speed by a coarse adjustment motor (15) via gears (12, 13) to cause a metal mold (3) to be opened or closed at a high speed. During the clamping of the mold, the ball screw (8) is driven by a fine adjustment motor (14) via gears (10, 11), which have a large reduction ratio and which are adapted to amplify the rotational force, and a clutch (9), so that the metal molds (3, 4) are clamped with a large force.

摘要： An inexpensive injection driving device which generates a large output torque and which exhibits good acceleration and deceleration characteristics in an injection molding machine in which a screw is driven by a servo motor to perform the injection. One or more ball screws (7) for driving the screw (2) in the axial direction are driven by a plurality of servo motors (M1, M2) and a position detector (P1) for detecting the screw position is provided for one servo motor (M1) only while power amplifiers are provided for each of the servo motors (M1, M2) and the power amplifiers are controlled by one control circuit, in order to control the servo motors (M1, M2) in synchronism with each other.

摘要： A compact, simply constructed ejector-carrying straight hydraulic mold clamping system in which a mold clamping force can be applied uniformly to a movable platen. A hollow cylindrical pusher member (12) and a movable platen (3) are combined with each other at a single annular connecting surface of each thereof, and a driving force is applied to the movable platen uniformly via the pusher member. An ejector (1) in the mold clamping system (2) is provided with a ball nut (7) in a hollow portion of the pusher member, and a ball screw (6) engaged with the ball nut is provided coaxially with a mold clamping ball screw (8), an ejector pin (4) being connected firmly to the front end portion of the ball screw (6), the rear end portion of the ball screw (6) being fitted withdrawably in a bore (8a) in the front end portion of the mold clamping ball screw (8). This enables the axial length of the mold clamping system to be reduced.
