| A method of making a turbomachine part, wherein the can include machining a blank into a base having blades extending therefrom, the blades defining a channel therebetween. The method can also include forming a bridge in the channel between the blades, and forming a cover on the tops of the blades and over the channel, such that the base, the blades, and the cover form a single substantially homogenous turbomachine part once the bridge is removed. | ||||||
| 133 | Cope/drag interface sealing article for the metal casting industry, and method | US10676603 | 2003-10-01 | US20050072551A1 | 2005-04-07 | Anatoliy Sorokin; Vincent Losacco; Don Eisenhour |
| A fiber-reinforced sealing article disposed between an upper sand mold portion (cope) and lower sand mold portion (drag) to fill in, or correct irregularities in green sand molds. In casting metal shapes in a sand/binder mold, the cope and/or drag mold portions include sand compositions that are not perfectly planar surrounding the mold cavity, leaving one or more areas where the cope and drag are not in contact or otherwise provide a seal surrounding the mold cavity. The fiber-reinforced clay-containing article described herein is disposed between the cope and drag to seal the mold in one or more locations surrounding the mold cavity. The composition described herein is capable of shaping by hand, like modeling clay; and the article is preferably in the form of a continuous rope that is flexible, remains hydrated, and can be cut or broken to a desired length and disposed in area(s) where the cope and drag do not make good mating contact. | ||||||
| 134 | Investment molding flask assembly | US09952358 | 2001-09-12 | US20030047299A1 | 2003-03-13 | Ching-Wen Ma |
| An investment molding flask assembly having a base with a central positioning boss protruded from a center thereof and at least one positioning annular groove defined therein around the central positioning boss, and a conical sleeve formed with a small opening end to be securely positioned on the base without any displacement in horizontal directions by means of the central positioning boss or the positioning annular groove. Whereby, the conical sleeve can be readily removable from a solidified semi-finished investment mold, and then the solidified semi-finished investment mold is sent into an oven independently for heating. Therefore the sleeve can be used repeatedly, and the investment mold can be manufactured rapidly and readily. | ||||||

| Flask-bound molds include two molding-flask halves, which have means (15) for the transport thereof on automatic mold systems. The molding flask receives a bound sand mold (8), which has cores (13), a pouring funnel (6) and a feeder passage (9). In order to be able to cast complicated castings also out of aluminum in such molds and to avoid the expensive finish work for the feeder and pouring funnel and in order to guarantee at the same time good core ventilation, the molding flask (4) has in the area of its parting plane a recess extending over at least a portion of the length and width of one side of the molding flask, whereby the pouring funnel (6) and the feeder (9) end in the area of the recess and the feeder is constructed within the sand mold (8) of the mold (1). | ||||||
| 137 | Drag mold release mechanism | US30982 | 1998-02-26 | US5853042A | 1998-12-29 | William A. Hunter |
| The drag flask has at least two opposed sides which include recesses proximate the matchplate. Manifolds are provided in the recesses to communicate compressed air from a source of compressed air to air inlets provided in the manifold. The manifolds are separated from the recesses using an elastomeric seal which is contoured to direct the compressed air between an air passage disposed between the drag mold and the matchplate. When incorporated into a sand mold forming machine, sensors are positioned on the sand mold forming machine to detect when the drag flask has reached a releasing position to thereby cause the source of compressed air to inject air into the manifold and air passage for release of the drag mold from the drag flask. | ||||||
