  • Patent number: 11312055
    Abstract: An extruder having an extruder crosshead, a die, and a die retaining assembly. The extruder crosshead has an annular major surface while the die has a first die surface facing and conformal to that major surface. The die also has a second die surface opposed to the first die surface. The die-retaining assembly is attached to the extruder crosshead, evenly and variably pressing the second die surface with controlled pressure such that the substantially opposing first die surface is pressed into the major surface of the extruder crosshead. The die-retaining also includes movable elements which abut the die in order to move the die. The die-retaining assembly can be used to evenly reduce the pressure exerted by over the second die surface so that the position adjustment elements can be used to more easily adjust the position of the die.

  • Patent number: 11298897
    Abstract: A method of manufacturing a cured composite structure includes inserting a plurality of radius filler segments into a radius cavity extending along a length of an uncured composite base member to form an uncured structural assembly. The plurality of radius filler segments are placed in end-to-end arrangement within the radius cavity and each having opposing segment ends and being formed of a thermoplastic material. The method additionally includes heating the structural assembly at least to a base member cure temperature that causes the segment ends of end-to-end pairs of the plurality of radius filler segments to fuse together and form a continuous radius filler element that extends along the length of the composite base member. The method also includes allowing the structural assembly to cure to form a cured composite structure.

An injector extends through the bore of the co-extrusion die along the nozzle axis. The injector and nozzle together form a dough into a rope that is tubular with a wall portion and an inner cavity surrounded by the wall portion as the dough is extruded out of the nozzle exit and about the injector. A compressed gas source provides a compressed gas out of an injector outlet and into the inner cavity of the rope to radially stretch the wall portion of the rope as the rope is dispersed from the injector. The co-extrusion die is spaced from the extruder to define a void therebetween. A delivery system delivers an entrainable material to the compressed gas in a pipe. The pipe is connected to an injector inlet of the injector in the void.

  • Patent number: 8905745
    Abstract: A mold core includes first and second main bodies and an adjustment assembly. The first main body includes a front surface, a rear surface opposite to the front surface, and a receiving cavity passing through the front and rear surfaces. The front surface defines two first cavities at opposite sides of the receiving cavity. A connection line of centers of the first cavities intersects with a symmetry axis of the first cavities to form a first intersection point. The second main body includes a forming surface defining second cavities. A connection line of centers of the molding cavities intersects with a symmetry axis of the second cavities to form a second intersection point. The forming surface is coplanar with the front surface. The adjustment assembly abuts the first and the second main bodies to compensate an offset between the first and second intersection points to satisfy a predetermined range.
