Abstract
An investment mold slurry curtain apparatus includes a slurry curtain of a slurry fluid, the slurry curtain having a length and a thickness, the length substantially greater than the thickness. The apparatus also includes an outlet configured to dispense the slurry fluid and form the slurry curtain. The investment mold slurry curtain apparatus may include and be described as an investment mold slurry coating apparatus including a conduit configured to receive a flow of a slurry fluid and an outlet operatively coupled to the conduit, the outlet configured to dispense the flow of the slurry as a curtain of the slurry.
Claims39
An investment mold slurry curtain apparatus, comprising:
- a first plurality of outlets having a longitudinal axis and a latitudinal axis, each of the first plurality of outlets configured to dispense an investment mold slurry fluid and form a slurry curtain of the investment mold slurry fluid,
- wherein the first plurality of outlets is arranged to form the slurry curtain having a length and a thickness, the length greater than the thickness,
- wherein at least one of the first plurality of outlets comprises at least one moveable plate that is movable along the longitudinal axis or an axis diagonal to the longitudinal axis of the outlet to define an outlet shape having a length and a thickness, the length and the thickness of the outlet shape is adjustable by moving the at least one moveable plate along the longitudinal axis or the axis diagonal to the longitudinal axis of the outlet so that a shape of the slurry curtain is adjustable with the length of the outlet shape being substantially greater than the thickness of the outlet shape;
- and
- a second plurality of outlets, each of the second plurality of outlets configured to dispense a stucco and form a stucco curtain.
An investment mold slurry coating apparatus, comprising:
- a conduit configured to receive a flow of an investment mold slurry fluid;
- a first plurality of outlets having a longitudinal axis and an axis diagonal to the longitudinal axis operatively coupled to the conduit and configured to dispense the flow of the investment mold slurry fluid as a slurry curtain,
- wherein at least one of the first plurality of outlets comprises at least one moveable plate that is movable along the longitudinal axis or the axis diagonal to the longitudinal axis of the outlet to define an outlet shape having a length and thickness, the length and the thickness of the outlet shape is adjustable by moving the moveable plate along the longitudinal axis or the axis diagonal to the longitudinal axis of the outlet so that a shape of the slurry curtain is adjustable wherein the length of the outlet shape is substantially greater than the thickness of the outlet shape;
- and
- a second plurality of outlets, each of the second plurality of outlets configured to dispense a stucco and form a stucco coating.
An investment mold slurry coating manifold apparatus, comprising:
- a plurality of slurry manifolds, each having a slurry chamber configured to receive a flow of investment mold slurry fluid, and an inlet conduit disposed on the slurry manifold, the inlet conduit having an inlet opening into the slurry chamber, the inlet conduit configured to provide the flow of the investment mold slurry fluid into the slurry chamber;
- a first plurality of outlets having a longitudinal axis and an axis diagonal to the longitudinal axis configured to dispense the flow of investment mold slurry fluid as a first slurry curtain;
- wherein at least one of the first plurality of outlets comprises at least one moveable plate that is movable along the longitudinal axis or the axis diagonal to the longitudinal axis of the outlet to define an outlet shape having a length and a thickness, the length and the thickness of the outlet shape is adjustable by moving the moveable plate along the longitudinal axis or the axis diagonal to the longitudinal axis of the outlet so that a shape of the first slurry curtain is adjustable wherein the length of the outlet shape is substantially greater than the thickness of the outlet shape;
- and
- a second plurality of outlets configured to dispense the flow of stucco as a stucco curtain.
