Abstract: A mold clamping device for an injection molding machine wherein a movable table which supports a movable mold is moved in directions approaching and moving away from a fixed table which supports a fixed mold to thereby bring the molds into open and closed states, and wherein mold clamping is effected in a closed state of the molds by mold clamping cylinders. The mold clamping device includes tie rods for guiding the movement of the movable table, the tie rods projecting upward from the fixed table and being each provided with an engaging groove such as threads or the like formed on the outer peripheral surface of its portion projecting from the movable table to the side opposite to the fixed table in the closed state of the molds; and split mold-like locking members capable of engaging with and disengaging from the tie rods each through each engaging groove in the closed state of the molds, the locking members being slidable in the axial direction of the tie rods. The mold clamping cylinders are disposed between the locking members and the movable table. Since the tie rods which receive the mold clamping reaction are so constructed as to also be employable as guide members for guiding the movement of the movable table, it is possible to attain a structural simplification and reduction in size in addition to advantage in terms of maintenance.

Abstract: A mold aligning method and device for a compression molding machine comprising a bed, uprights standing upright on the bed, a crown block joined to the tops of the uprights, a slide block guided for vertical sliding movement by the uprights, and a hydraulic cylinder actuator mounted on the crown block to drive the slide block for vertical sliding movement, for maintaining an upper mold attached to the lower surface of the slide block in parallel to a mating lower mold during a compression-molding operation. The mold aligning device comprises a plurality of mold position adjusting cylinder actuators disposed on the bed, position detectors associated respectively with the mold position adjusting cylinder actuators to detect the strokes of the latter, a hydraulic source for driving the mold position adjusting cylinder actuators, and a control unit for controlling the strokes of the piston rods of the mold position adjusting cylinder actuators with reference to the zero points of the piston rods of the mold position adjusting cylinder actuators determined beforehand. The zero points are decided by placing the upper mold in close contact with the lower mold and extending the piston rods of the mold position adjusting cylinder actuators so that the piston rods are pressed against the lower surface of the slide block. The strokes of the piston rods are controlled during a compression-molding operation so that the upper mold is maintained precisely in parallel to the lower mold.

Abstract: A method of controlling a hydraulic press wherein changing over from velocity control to pressure control can be effected at an optimum point of time in accordance with a condition of material being filled. When a movable mold half of a metal mold is moved by a hydraulic cylinder to compression mold a work within a cavity defined in the metal mold, the velocity of movement of the mold half by the hydraulic cylinder is controlled until pressurization of the work is started, but after starting of the pressurization, the pressurizing force of the hydraulic cylinder is controlled. During the velocity control, a parameter which varies as the compression proceeds is successively detected during the velocity control, and changing over from the velocity control to the pressure control is effected at a point of time when the detected parameter coincides with a preset value--that is, when the work is fully filled in the cavity. A device for controlling a hydraulic press is also disclosed wherein optimal pressure control can be assured in accordance with a current condition of material for molding.

Abstract: A hydraulic press includes a fixed mold, a movable mold movable closely to or separately from the fixed mold, a hydraulic cylinder for moving and pressing the movable mold, and a hydraulic circuit for controlling the supply of a pressing oil in the hydraulic cylinder. The hydraulic circuit includes: a variable capacity pump connected to the hydraulic cylinder by an oil tube through a solenoid direction switching valve; a solenoid proportional flow control valve interposed on the way of an oil tube bypassing the solenoid direction switching valve; a detecting sensor for detecting the position or speed of the movable mold; a speed setter for setting the pressing speed of the movable mold; and a controller for comparing the output value of the detecting sensor with a speed set-up value thereby adjusting the opening of the solenoid proportional flow control valve. With this construction, it is possible to smoothly control the pressing speed in a low speed pressing region of the movable mold irrespective of the leaked oil amount and load on the pressing cylinder side.

Abstract: A molding compound metering system meters a molding compound in supplying the molding compound from a molding compound stocker into the injection chamber of an injection barrel by detecting the backward stroke of the injection plunger of an injection cylinder, axially slidably fitted in the injection chamber and detecting the pressure of the molding compound in the injection chamber of the injection barrel. When the injection plunger is moved backward by the pressure of the molding compound supplied into the injection chamber, the discharge of the working fluid from the back working chamber of the injection cylinder is regulated to apply back pressure to the injection plunger by an adjustable-pressure relief valve, and a regulated pressure is applied to the front working chamber of the injection cylinder. Thus, the adjustable-pressure relief valve is able to regulate the back pressure in a relatively high pressure range and, consequently, the back pressure can be accurately regulated to enhance the reliability of the metering operation.
