  • Patent number: 11090723
    Abstract: This support member for additive manufacturing is a support to be disposed below a manufactured portion of a particular overhanging portion of the three-dimensional object which needs the support in the process of additively manufacturing the three-dimensional object. The support member is provided with: the support main body; and a polishing channel which is formed in the support main body so as not to be exposed to an interface with the three-dimensional object, and through which a polisher for polishing and removing the support main body is allowed to pass.

  • Patent number: 11040502
    Abstract: A method for producing a fiber-reinforced resin molded article includes disposing a suction medium, a resin barrier aeration medium and a fiber base material in a cavity such that the suction medium is disposed between an end part of the fiber base material and a mold, and the resin barrier aeration medium is disposed between the suction medium and the end part of the fiber base material. The method further includes: impregnating the fiber base material with a resin by injecting the resin from an injection part, while reducing a pressure in the cavity by suction from a suction part; curing the resin with which the fiber base material is impregnated; and releasing a fiber-reinforced resin in which the fiber base material and the resin are integrated.

  • Publication number: 20190160721
    Abstract: Provided is a half nut opening/closing device that makes it possible to easily secure engagement between a tie rod and a half nut even if the tie rod to be engaged is bent. The half nut opening/closing device according to the present invention includes a half nut including a half nut piece and a half nut piece that are moved between a closed position and an open position and engage with a tie rod at the closed position, and an alignment roller that is provided on one or both of the half nut piece and the half nut piece, and is configured to convert moving force, of that the half nut piece and the half nut piece move to the closed position, into upward force in a vertical direction to lift and align the tie rod.

  • Patent number: 8641400
    Abstract: There is provided a mold clamping apparatus that can prevent a molding material from spouting from a split surface of a mold even if in-cavity resin pressure causes offset of a mold opening force, and can extend the life of the mold. The mold clamping apparatus includes a control device that estimates a mold opening force by mold internal pressure for molding with mold internal pressure being asymmetrical with respect to a center of a mold block, determines a mold clamping hydraulic value applied to each tie bar correspondingly to the estimated mold opening force, and distributes hydraulic pressure supplied to each tie bar so that the determined mold clamping hydraulic value is reached.
