| 101 | Apparatus for deburring moulds and cores | US187076 | 1994-01-27 | US5477908A | 1995-12-26 | Werner Landua |
| An apparatus for removing burrs in confined spaces of molds or cores is disclosed. The apparatus includes a retaining body; and at least one deburring element resiliently mounted in an unloaded state on an outer circumference of the retaining body. The at least one deburring element has a ring containing a separating point. The separating point is inclined to a longitudinal axis of the retaining body at an angle of 45.degree.. Alternatively, in accordance with the invention, at least one deburring element is resiliently mounted in an unloaded state on an outer circumference of the retaining body. Each deburring element has a deburring portion projecting radially outward from a remainder of the deburring element for removing the burrs and is retained in the outer circumference to be axially displaceable with the retaining body in a first axial direction and in a second axial direction opposite to the first axial direction. Each deburring element is displaceable radially inward during motion of the retaining body in the first axial direction and displaced radially outward during axial motion of the retaining body in the second axial direction. | ||||||

| A method is disclosed for producing a hollow airfoil, specifically, a blade or vane for a gas turbine engine, which is formed with a complex interior for cooling purposes. Broadly, the method comprises the steps of molding a green ceramic core having outer surfaces generally contoured to produce the intended interior surfaces of the completed airfoil, heating the green ceramic core to a sufficient extent to produce a fired core, and operating on the fired core with a laser to modify the characteristics of the fired core. Use of the laser enables the formation of detailed features having a transverse dimension less than approximately 0.020 inches. Specific operations may include labeling, trimming, cutting, drilling either by punching or trepanning, etching or milling, and glazing or strengthening. In another embodiment of the invention, a layer is produced on the core surface having a very high surface energy to promote the flow of the casting alloy around the core within the mold. | ||||||

| A mold comprising a cavity for defining the shape of a casting and a mold body for forming said cavity, comprising: a mold body formed of an ordinary temperature setting resin or thermosetting resin and casting sand, said mold body having a surface layer portion on the surfaces thereof including depressions, said depressions in the surface layer portion being filled up with at least one porous powdered material selected from the group consisting of hydrous magnesium silicate clay mineral, activated carbon and activated alumina, thereby providing the mold body with smooth surfaces whereby said mold generates less amount of material such as gums which cause defective castings during casting since molten metal is restrained from intruding into the walls of said mold. | ||||||

The present invention provides a method of forming a leading edge for an aerofoil component e.g. an aerofoil blade. The method comprises forming a pre-form having a precursor edge and processing said precursor edge to form the leading edge. The pre-form is formed using metal injection molding. The leading edge may have an elliptical profile.

A method and casting core (310) for forming a landing (13) for welding a baffle (40) inserted into an airfoil (20) are disclosed. The baffle landing (13) of the blade or vane is formed in investment casting by the casting core (310) rather than by wax, reducing tolerances and variability in the location of the baffle (40) inserted into the cooling cavity (30) of airfoil (20) when the baffle (40) is welded to the baffle landing (13).

| A technique for removing loose powder (31) from the interior surfaces of a ceramic mold (17) made using layer manufacturing processes, such as three-dimensional printing processes. The interior of a mold (17) can be filled with water (21) which is boiled and the particles are entrained in the flow caused by the boiling liquid. Alternatively, fine particles (51) are introduced into the mold (47) and agitated in the mold (47) to dislodge the particles (51) and the powder so that they can be poured out of the mold (47). Such technique tends also to remove the surface finish of the mold (47). Any of the particles (51) which remain can be dissolved in a liquid and removed in the liquid from the mold (47). Further, the surface finish of the mold (47) can be improved by casting a slip of fine particles on to the surface to form a generally level, and preferably non-conformal, coating on the surfaces. | ||||||
