Abstract: An arrangement for carrying out a two-stage linear movement with a stationary and a movable constructional unit, comprises a hydraulic cylinder and an hydraulic piston preferably in the form of a plunger. The hydraulic piston has a hollow volume which houses a plunger piston which, in turn, rests on a spindle rotated by a servomotor in the movable construct-ional unit. The plunger piston can be displaced axially in the hydraulic piston and also in the hydraulic cylinder by use of the spindle.

Abstract: An ejector mechanism which is simple in structure and facilitates the manufacture and assembling thereof, wherein a ball screw-spline shaft (10) of the ejector mechanism has a spline portion (11) fitted into a ball spline nut (20) fixed to a movable platen (1) of an injection molding machine, and a ball screw portion (12) threadedly engaged with a ball nut (30) which is rotatably supported by a casing (40) fixed to the movable platen. The ball nut is coupled to a motor (51) by toothed pulleys (52, 53) respectively secured to the ball nut and the output shaft of the motor, and a timing belt (54) looped round these pulleys. As the ball nut is rotated through motor rotation, the spline portion advances together with the ball screw portion, and a molded article is ejected by the distal end of the spline portion which acts as a molded article-ejecting portion.

Abstract: Part ejection apparatus for ejecting molded parts from a mold carried by a movable platen in an injection molding machine. A plurality of linearly operating hydraulic cylinders are provided to move an ejector bar that is carried along guide rods supported by a movable platen so that the ejector bar moves toward and away from a mold member that is carried by the movable platen. Suitable connections can be provided between the ejector bar and the ejection mechanism of the mold to drive ejector pins carried by the mold for separating the molded part from the mold surface. Additionally, a rotary motor is also carried by the movable platen and has its axis coincident with the longitudinal axis of the movable platen for connection of an output shaft of the motor with a drive mechanism carried by a mold, the drive mechanism suitable for rotating rotatable cores that form internal threads on the molded article. The linear and rotary ejection apparatus can be used individually, or they can be used in appropriate sequence in a core-type mold where separation of the cores does not simultaneously effect separation of the part from the mold.

Abstract: A product ejector in a motor-driven, direct-acting type hydraulic mold clamping system, which includes a rod mounted on a ball screw for driving a moving platen at a forward end of the screw on the side of the platen, so that the rod is immovable axially and engageable with and disengageable from an ejector plate attached to an ejector bar slidably arranged within a bore in the platen. When the platen moves rearwardly, the ejector plate, moving together with the platen, is abutted against the rod. As the platen moves farther rearwardly, the rod causes the ejector bar to project into a mold mounted to the platen, against the force of a spring inteposed between the ejector plate and the platen, to eject a molded article.

Abstract: A method is disclosed for selectively separating runners and molded products from an injection mold assembly. The apparatus comprises first and second mold portions having mating surfaces formed to define a runner channel and product cavity. A plurality of ejector pins are disposed within the second mold portion and adapted to translate within the second mold portion so as to retractably extend into the cavities for forming the runner and molded product. An ejector plate assembly is provided which translates the ejector pins a predetermined distance within the mold. A pin extension mechanism is connected to the ejector plate assembly and at least one ejector pin. The pin extension mechanism is adapted to selectively extend the connected ejector pin a predetermined distance beyond the stroke of the ejector plate assembly such that the connected pin is extended into contact with the channels for forming the runner, or the molded product.

Abstract: A mold ejector multiplier is described in which the mold ejector is attached to the fast acting piston of a dual piston hydraulic device consisting of a main cylinder having a closed bottom adapted to act both as a cylinder and as a reservoir for hydraulic fluid with an outer piston adapted to reciprocate in the cylinder and an inner piston adapted to reciprocate in a cylindrical bore in the outer piston. Both pistons are in contact with the hydraulic fluid in the hydraulic fluid reservoir, so that when one piston is pushed in, the other automatically is pushed out and vice versa. The relative size of the two pistons, advantageously, is such that the inner piston moves more than one unit length for each unit length of movement of the outer piston. The device is mounted in the actuating plate of the mold ejector system with the inner piston connected to a mold ejector and the outer piston arranged to abut a stationary part of the mold when the actuating plate is moved to actuate the ejectors. Engagement of the outer piston by the fixed part of the mold causes it to enter the cylinder and to propel the inner piston out. This multiplies the rate at which the ejector is moved into contact with the workpiece so that the workpiece can be dislodged and ejected from the mold without manual intervention.

Abstract: A HIGH PRESSURE RAPID ACTING CLOSURE APPARATUS FOR INJECTION MOLDING APPLICATIONS AND THE LIKE IS DESCRIBED. A CLOSURE MEMBER FOR HIGH PRESSURE WORKNG IN A WORKING REGION SUCH AS AN INJECTION MOLD IS RECIPROCATINGLY MOUNTED TO A FRAME. THE CLOSURE MEMBER IS RECIPROCATED WITH A LEAD SCREW AND ASSOCIATED NUT. THE SCREW THREAD EFFECTIVE BETWEEN THE LEAD SCREW AND NUT IS APPORTIONED INTO A HIGH SPEED, LOW FRICTIONAL SECTION FOR PREDETERMINED PORTION OF THE RECIPROCATING STROKE AND A HIGH AXIAL STRENGTH BEARING ENHANCED FRICTIONAL SECTION OPERATIVE FOR THE REMAINDER OF THE STROKE. HIGH PRESSURE OPERATION IS EFFECTED WHEN THE SECOND HIGH AXIAL STRENGTH PORTION OF THE SCREW THREAD IS EFFECTIVE BETWEEN THE NUT AND LEAD SCREW. THE CLOSURE APPARATUS MAY BE OPERATED AT HIGH SPEEDS WITH LITTLE HEATING.
