摘要： Apparatus for forming a pour hole and main sprue in an investment mold for lost wax casting. A sprue having a flared base, a base member adapted to receive the flared base of the sprue for vertically supporting the sprue, and a flask for containing investment material immersing the sprue, define the casting apparatus of the present invention. The present investment casting sprue apparatus forms a pour hole in the hardened investment material suitable for smoothly introducing liquid metals into the cavity formed by the sprue, thereby reducing the number of casting defects related to turbulent filling. This is accomplished as a result of the flared base of the sprue, which forms a gentle transition into the sprue. The current practice, by contrast, uses a sprue having a cylindrical base which is simply inserted into a hole in a finger or button formed in the supporting base member for the sprue without regard to this smooth transition. The design of the present base member permits ready removal thereof from the hardened investment material without damage to the sprue or to the investment material, thereby reducing the number of inclusion defects in the castings.

摘要： A full mold casting process in which a complete, positive model made of a thermally decomposable material is placed in a molding box and filled with sand; the sand is hardened by shaking. Casting metal is poured on the thermally decomposable model and the model is decomposed by the casting heat. In order to fill up the cavities of the model and mold moldings with crucial cavities, reliably with the molding sand, the model is provided with pass-through apertures. By introducing the flow-through holes into the casting model, preferably through the flange and button sides, all cavities of the casting model are completely filled with sand and the latter is compressed against the model. The rising of the sand in the model cavity is facilitated by the fact that the filling level of the molding sand is kept nearly constant near the model cavity to be filled until the cavity is completely filled.

摘要： A fugitive pattern of an article to be investment cast wherein the pattern includes a plurality of locator embossments disposed in an array to provide a datum reference system by which the pattern can be held and positioned by a manipulator, such as for example a gripper device to a computer controlled robotic device, for assembly with another component of the pattern assembly. The datum embossments are located on a portion of the pattern that will be removed from the final metallic casting made to replicate the pattern. The casting includes integral cast datum embossments thereon by which the casting can be held and positioned.

摘要： A casting includes a heat transfer surface having a plurality of cavities. The plurality of cavities include a density of at least about 25 cavities per square centimeter to about 1,100 cavities per square centimeter resulting in increased surface area and therefore enhanced heat transfer capability. Also disclosed is a mold for forming a pattern for molding the casting. The mold includes a surface defining a portion of a chamber to which are attached a plurality of particles having an average particle size in a range of about 300 microns to about 2,000 microns.

摘要： A method for manufacturing a core mold for foam-molding 1, provided with a concavo-convex pattern 5 on its mold surface 1a for forming a design pattern 4 on the surface 3a of a foam-molded article 3, comprises the steps of forming a reverse concavo-convex pattern 7 that is reverse of the concavo-convex pattern 5 on the surface 6a of a core mold making model 6 made of a conductive material having the same shape as the mold surface 1a, and transferring the reverse concavo-convex pattern 7 by electric discharge machining to the mold surface 1a, so as to form the concavo-convex pattern 5.

摘要： A crankshaft casting pattern insert 10 which includes selectively adjustable portions 14, 16, which respectively correspond the front and rear main bearing journal portions of the crankshaft. Each adjustable portion 14, 16 includes a removable insert or member 18, a key member 20, several “vertical” spacers 22, several “lateral” spacers 24, and a fastener 26. Adjustable portions 14, 16 allow the pattern 10 to be selectively modified in shape, effective to compensate for pattern wear and to allow multiple crankshafts to be produced which have a substantially similar balance capability. Pattern 10 may also include several validation pads or points 50 which allow the produced crankshafts to be measured with improved accuracy.
