  • Patent number: 10401849
    Abstract: The velocity and force of a target is controlled to have a predetermined relationship, independently of changes in the velocity at which the target is driven using a velocity command value and in an external force from the target. A controller controls a control target, driven to generate a predetermined viscous force as a reaction force, by periodically outputting a command value to the control target using a target value calculated from a command pattern for driving the control target and a feedback value from the control target relative to the target value. A correction operation unit obtains a control physical quantity different from the command value, calculates a correction command value based on a relationship between an error of the obtained control physical quantity from its target value and an error of the feedback value from the target value, and outputs the correction command value to the control target.

  • Patent number: 10226889
    Abstract: A injection molding method involves measuring, using at least one external sensor, a change in a parameter of a mold side of a mold cavity, approximating a condition within the mold cavity based on the change in the parameter, such as pressure within the mold cavity or flow front position, and comparing the approximated condition to a trigger point. If the approximated condition equals or exceeds the trigger point, activating a virtual cavity sensor having an optimal pre-defined pressure-time curve, and upon activation, the virtual cavity sensor tracks an approximated condition calculated from the change in parameter measurements measured by the at least one external sensor over time. In an embodiment, results of the approximated parameter tracking can be used in conjunction with an optimal pre-defined pressure-time curve.

  • Patent number: 9339961
    Abstract: During metering, a screw is retreated to a preset metering completion position while it is being forwardly rotated. Pilot injection is performed such that the screw is reversely rotated and advanced so that a resin pressure reaches a predetermined compression pressure, during a time period between the end of the metering and the start of injection. The screw reverse rotation is continued before the screw advance is started for the pilot injection. In this way, a check valve can be closed at a relatively low pressure such that precision metering can be achieved.

    Abstract: Molded articles are prepared from propylene-ethylene copolymers and exhibiting improved clarity and strength properties. Articles prepared include bottles and other thin-walled articles. The articles are prepared using an isotactic propylene-ethylene random copolymer resin having an ethylene content of from about 0.5 to about 3 percent by total weight of copolymer, with a xylene solubles content of less than about 1.5 percent. The injection molded article may exhibit less than about 20 percent haze, as determined by ASTM D1003, at a thickness of about 0.08 inch (2.03 mm). Articles may also be prepared from similar copolymers having an ethylene content greater than about 3 percent by total weight of copolymer, with a xylene solubles content of less than about 4 percent by total weight of copolymer. These articles may exhibit less than about 13 percent haze, as determined by ASTM D1003, at a thickness of about 0.08 inch (2.03 mm).

  • Patent number: 9056417
    Abstract: A sweep core die device for a throttle body, or other part, has a cover insert and an ej insert that engage leaving voids therein, a ram component entering the voids, and cores connected to the ram component by ball joints and other components for simultaneous movement in several axes within the voids. The cores are mirror image and connect to one end of a mount. The other end of the mount pivotally connects to the ej insert. A shaft pivotally connects to each mount and to a clamp outwardly from the inserts. The clamp moves relative to the two inserts, moves the shafts, and thus rotates the cores inwardly and outwardly through the voids. The cores have the internal shape of the passage through each horn of a finished throttle body or other part. The cores produce passages so fuel attains laminar flow within the part.

  • Publication number: 20150137425
    Abstract: An apparatus simultaneously operates all split locking nuts of an injection molding machine two-platen clamp unit to engage and disengage the split locking nuts with clamp unit strain rods. Each split locking nut has opposed pivoting nut halves operated by coupling rotation of a rotating member through a predetermined angular range to the nut halves via translating members such as push rods. The push rods are pivotably connected to the rotating member and to the nut halves so that the direction of each push rod relative to the rotating member and to the nut half changes with rotation of the rotating member. A method of molding comprises: disengaging split locking nuts from strain rods; positioning a moveable platen assembly to abut mating mold components; simultaneously operating the split locking nuts to engage the strain rods; and, applying force to the abutted mold components sufficient for injection and cure of melt.
