  • Patent number: 9821498
    Abstract: In an injection molding method, using a heating cylinder having on the front end thereof a discharge nozzle, a single axis screw is rotatable inside the heating cylinder, a fiber-supplying device fills reinforcing fiber into the heating cylinder, and injection molding is performed while supplying the reinforcing fiber and the resin starting material separately and supplying the reinforcing fiber on the front side of the resin starting material. The method includes a plasticization process for obtaining a specified amount of a kneaded product by retracting the screw while rotating in the normal direction to melt the resin starting material and knead reinforcing fiber into the melted resin starting material, and an injection process for discharging the kneaded product from the discharge nozzle by advancing the screw. Reinforcing fiber is supplied into the heating cylinder in the injection process.

  • Patent number: 9815234
    Abstract: An injection molding machine includes a base, a stationary platen fixed to the base for holding a first mold section, and a moving platen for holding a second mold section. The moving platen is slidably supported on a platen slide surface fixed to the base and moveable along a machine axis between a mold closed position, in which the moving platen is drawn towards the stationary platen, and a maximum daylight position, in which the moveable platen is spaced axially apart from the stationary platen by a platen opening. The machine further includes a carriage support structure slidably supporting a stack mold carriage for holding a mold center section. The stack mold carriage is translatable parallel to the machine axis between a carriage advanced position and a carriage retracted position spaced axially apart from the carriage advanced position by a carriage stroke length.
