Molding Pressure Control Means Responsive To Pressure At Shaping Area (e.g., Injection Or Press Mold, Etc.) Patents (Class 425/149)
  • Patent number: 10500776
    Abstract: A brake control method for an injection molding machine includes the steps of obtaining mold clamping force information indicating the mold clamping force of a mold opening/closing mechanism and determining whether or not the mold clamping force of the mold opening/closing mechanism exceeds a predetermined value, based on the mold clamping force information. When the mold clamping force of the mold opening/closing mechanism does not exceed the predetermined value and when a servo amplifier cuts off the supply of power to a servomotor that drives the mold opening/closing mechanism, a brake mechanism for applying braking force to the mold opening/closing mechanism is actuated. On the other hand, when the mold clamping force of the mold opening/closing mechanism exceeds the predetermined value, the brake mechanism will not be actuated.

  • Patent number: 10399264
    Abstract: Embodiments within the scope of the present disclosure are directed to external sensor kits that may be included in new injection molds or retrofitted into existing injection molds in order to approximate conditions within a mold, such as pressure or the location of a melt flow front. Such kits are designed to amplify meaningful measurements obtained by the external sensor kit so that noise measurements do not prevent the approximation of conditions within a mold. In some embodiments within the scope of the present disclosure, an external sensor kit includes a strain gauge sensor, a coupon, a support bracket, and a hammer. The strain gauge sensor is placed on a surface of the coupon and measures the strain in the coupon.

    Abstract: A process and apparatus for densification of material compresses the material, then heats and cools the compressed material to provide structural integrity and durability to the resultant densified product. For a lignocellulosic biomass material an inherent binder is used. The binder is activated substantially only along the periphery of the compressed material to increase throughput and reduce energy used during the densification process. To optimize throughput and densified material density and durability, the process and apparatus includes a compaction pressure measurement that provides a signal to a constrictor located at the exit, or between the exit and initial compaction location, to automatically control compaction pressure as material type, initial density, moisture and load weight vary.

  • Publication number: 20140339736
    Abstract: The described embodiments relate generally to improvements to injection molding equipment. More specifically, concepts for reducing sink and improving cosmetics of portions of injection molded parts in close proximity to gate areas of an injection mold are disclosed. A cold runner system is described in which molding material disposed in a mold cavity is separated from excess molding material in the runner system shortly after the mold is filled at a predetermined packing pressure.

  • Patent number: 8882486
    Abstract: To execute a stable pressure control, in a control device for an injection molding machine, a filling/pressure-keeping determining unit determines whether the injection molding machine is performing a pressure keeping operation, an elastic constant identifier acquires, when the filling/pressure-keeping determining unit determines that the pressure keeping operation is in progress, a pressure detection value and a position detection value as operation information of a motor and identifies an elastic constant K based on the acquired pressure detection value and the position detection value, and a pressure-control control-parameter setting unit calculates a proportional gain Ka of a pressure controller such that a product of the proportional gain Ka of the pressure controller and the elastic constant K is smaller than a speed control bandwidth ?sc of a speed controller, and sets the calculated proportional gain Ka to the pressure controller.

  • Publication number: 20140314892
    Abstract: An injection apparatus includes a pressure accumulating portion connected to an operation chamber of an injection cylinder. A control unit controls the speed at which the injection cylinder moves and is connected to a rod of the injection cylinder. The control unit includes a rotary shaft that follows the movement of the rod and is capable of moving in the same direction as the rod, a conversion mechanism that converts the linear motion of the rod into the rotation of the rotary shaft, and a rotation member coupled to the rotary shaft. The control unit further includes a resistance generating member that generates a frictional resistance by coming into sliding contact with the rotation member, an actuating member that is moved by an electric drive source, and a movement mechanism that follows the movement of the actuating member and moves the resistance generating member relative to the rotation member.

  • Patent number: 8801414
    Abstract: In one embodiment, a system for forming aggregate materials may include a lower open-topped mold, an upper mold, an actuation assembly, a heating system, a pressure sensor, and a controller. The lower open-topped mold can receive a heat moldable material that can include a foaming agent. The lower open-topped mold can contact the heat moldable material and the upper mold can contact the heat moldable material. The controller can execute machine readable control logic to cause the actuation assembly to generate relative outward motion at an expansion rate. The foaming agent can expand the heat moldable material when heated. During outward motion, the lower open-topped mold can maintain close contact with the heat moldable material, and the upper mold can maintain close contact with the heat moldable material. The expansion rate of the relative outward motion can be based upon a pressure signal indicative of back pressure.
