  • Patent number: 11312051
    Abstract: An apparatus includes a stem connector configured to connect a movable piston with a valve stem, in which the movable piston is slidably receivable in a cylinder, and in which the cylinder is mountable to a distribution manifold of a molding system. The stem connector maintains connection between the movable piston and the valve stem while the valve stem is moved to selectively open or close a mold gate of a mold assembly installed in the molding system. The stem connector urges the movable piston to tilt at a tilt angle while the movable piston is moved along an interior of the cylinder, and in which the tilt angle is formed between a central piston axis extending through the movable piston and a central stem axis extends through the valve stem.

The constraining body includes a surface including a linear region along a first direction, and is opposed to the stage so that the linear region is the closest to the stage. The supply nozzle supplies a material curable by energy of an energy ray into a slit region between the stage and the linear region. The irradiation unit irradiates the supplied material with the energy ray through the constraining body. The movement mechanism moves the stage relative to the constraining body along a second direction for forming a cured layer of the material for one layer, and moves the constraining body and the stage relative to each other along a stacking direction for stacking the cured layers.

  • Patent number: 11077609
    Abstract: A building apparatus for building a three-dimensional object includes: an inkjet head that ejects ink as a building material; a scanning driver that causes the inkjet head to perform a scanning operation of moving relative to the object being built; a flattening roller that flattens a layer of the ink; and an ink removal unit that removes, from the flattening roller, the ink that is scraped off by the flattening roller. The ink removal unit includes a flow channel formation unit that forms a flow channel of fluid that enables the ink adhering to the flattening roller to be removed by causing the fluid for removing the ink to flow out or flow in, and removes the ink from the flattening roller without scraping off the ink from the flattening roller. Hence, flattening the layer of the building material more appropriately.
