20110049748 | METHOD FOR DEBURRING A CERAMIC FOUNDRY CORE - The present invention relates to a method for deburring a ceramic foundry core ( | 03-03-2011 |
20130040015 | TOOLING FOR INJECTION-MOLDING A PART - A tooling for injection-molding a part, the tooling including two cavity blocks each including a cavity formed therein of a shape corresponding to a shape of a part that is to be molded once the cavity blocks have been superposed, at least one of the cavity blocks including an ejection mechanism ejecting the molded part and including at least one ejector movable between a molding position and an ejection position. The ejector is guided to move between its two positions along a curved path, or a circular arc, of shape that corresponds to a shape of a portion of the mold part to be extracted from the cavity. | 02-14-2013 |
20130078335 | DEVICE FOR INJECTION-MOULDING A PART - A tooling for injection-molding a part, the tooling including two cavity blocks each including a cavity formed therein of a shape corresponding to a shape of a part that is to be molded once the cavity blocks have been superposed. At least one of the cavity blocks includes a mechanism for positioning a core, which mechanism includes at least one bearing surface for bearing against the core and at least one presser screw screwed into a threaded passage of the cavity block for purpose of holding the core in position against the bearing surface. The tooling further includes a force-limiter limiting force applied to the core by the presser screw. | 03-28-2013 |
20130174997 | MOULD FOR PRODUCING PARTS BY WAX INJECTION - A mold for producing a part, such as a turbomachine blade model, by injecting wax into a cavity, the cavity including at least two cavity elements, each of which is supported in a cavity block. The two cavity blocks are mobile relative to one another between a closed position for injecting the wax and an open position for removing the part following the injection of the wax. The two cavity blocks are mobile in a horizontal plane. | 07-11-2013 |
20130174998 | INJECTION MOLD FOR A WAX MODEL OF A TURBINE BLADE HAVING AN ISOSTATIC CORE HOLDER - The invention relates to an injection mold for producing a model of a turbine engine blade, comprising a top surface that folds onto a bottom surface, both surfaces having long rods for supporting a core ( | 07-11-2013 |
20140137409 | ADAPTIVE MACHINING METHOD FOR SMELTED BLADES - A method for finishing a shape of a component by machining, in which one area is produced by smelting with a thickened portion forming a first surface with a surrounding profile and a theoretical profile defined by a second surface, the method including: defining, on the second surface, a grid forming nodes and squares; defining each point over which the machining tool is to pass according to weighting coefficients equal to weight to be given to the nodes of the square in which the tool is located, to be the barycenter of assigned nodes of the coefficients; measuring, for each node located outside an outer limit, the delta between the first surface at the node and the theoretical position of the node; calculating deltas for each node within the outer limit by interpolation from already known deltas; using the weighting coefficients, defining the delta to be applied at each point. | 05-22-2014 |
20150081074 | METHOD FOR MACHINING THE TRAILING EDGE OF A TURBINE ENGINE BLADE - A method for manufacturing a turbine engine blade including an airfoil with a profile defined by a theoretical digital model, the method including: manufacturing a blank having a thickened portion along a trailing edge of the airfoil relative to the theoretical profile; removing the thickened portion by adaptive machining, including: positioning the blank in a reference frame; acquiring, by probing at a predetermined number of points on a first surface of the blank along the trailing edge, positions of the points in the reference frame; determining differences, in one direction, in position from corresponding points of the theoretical model; producing machining grids on the blank surface, peaks of the grids determined from the points; determining an amount of material to be removed from the surface of the grids, based on the position of the points relative to the peaks and the deviations in position; and machining the airfoil. | 03-19-2015 |
20150122445 | TOOL FOR MANUFACTURING A FOUNDRY CORE FOR A TURBINE ENGINE - A tooling for fabricating a foundry core, for making a circuit for cooling a blade of a turbine engine, the tooling including: a mold for injecting a paste and including imprints for a first portion and for at least one other portion of the core; a mechanism bearing against and/or engaging end portions of at least one ceramic rod that interconnects the portions of the core and that passes through the imprint for the first portion of the core; and a support mechanism in the imprint for the first portion of the core to support a substantially middle portion of the or each rod. | 05-07-2015 |
