摘要： A method of indexing moulds uses a flaskless moulding machine for forming moulds and a mould conveyor for carrying, and advancing a mould string produced from a plurality of the moulds received by the mould conveyor from the flaskless moulding machine. The method comprises: (i) forming one or more moulds one at a time using the flaskless moulding machine, each of the one or more moulds being added to the mould string while the mould string is stationary by being brought Into contact with the mould string, subsequently to being produced by the flaskless moulding machine. Once the one or more moulds has been produced and added to the mould string, the method continues in step (ii) by advancing the mould siring, in a single motion, away from the flaskless moulding machine a distance corresponding to the sum of the thicknesses of the one or more moulds using the mould conveyor, wherein the flaskless moulding machine assists the mould conveyor in advancing the mould string during a first part of the distance, and wherein the mould conveyor advances the mould string a second part of the distance, corresponding to the remainder of the distance, without assistance from the flaskless moulding machine. The single motion is continuous. A system for indexing moulds is also provided.

摘要： The use of green sand is eliminated by replacing green sand molds with all core sand assemblies that provide, during casting, both the internal and external surfaces of a casting, such as a cylinder head or engine block. In the process, a mold is formed from the same core sand that is used to form the core elements defining the internal passageways of the casting. A mold-core carrier is constructed with downwardly converging sides that hold assembled mold and core elements together, without fasteners, during transportation and pouring of the molten iron alloy into the mold-core assembly and the cooling period to form the casting. After the casting is formed, the core sand from both the mold elements and core elements is recovered, and may be recycled and processed to form further mold elements or core elements or both.

摘要： In a system comprising a gripper (9) and a number of gripping objects (7), and with fluid-communication couplings for establishing temporary fluid communication between the gripper (9) and the gripping object (7) being gripped, the novel feature consists in that the coupling comprise at least one tubular member (30) with at least one open end being adapted to be pressed against and to make fluid-tight contact with a plane surface (37) on the gripping object (7) having fluid-transfer openings (39) with somewhat smaller diameter than the open ends of the tubular member (30). With this arrangement, the risks of damage and other problems associated with previous coupling arrangements based on the male-female principle are avoided.

摘要： A register system is provided for making molds for metal casting which reduces flaws attributable to parting line shift. This is accomplished by urging the cope mold flask (11) against two fixed stops (50, 52) on the long axis, and one fixed stop (54) on the short axis of the flask. This same register principle is applied in the drag mold making station 18, where the drag flask (15) is urged against two fixed stops (86, 88) on the long axis, and one fixed stop (90) on the short axis of the flask. At the closer station (24), where the mold halves are assembled using the improved closer 150 which comprises in an assembly of cooperative association an upper support framework 160, an intermediate support framework 170 suspended from the upper support framework 160 as so to permit only pure vertical motion therebetween, a cope capture framework 180 freely suspended from the intermediate support framework 170, and a drag capture framework 190 which is suspended from the cope capture framework 180 so as to permit only pure axial translation therebetween. The flasks are properly aligned to the patterns at the mold making stations, and again properly aligned to each other at the closer station, so as to eliminate parting line shift problems of the mold halves.

摘要： Sand molds stored in a prepour storage system are retrieved and conveyed to a pouring station with a total mold cavity capacity equal to the amount of molten metal to be poured. Despite the fact that the mold cavities vary in size they are delivered to the pouring station in a sequence that accomodates delivery of the molds having variable metal capacity to one of a plurality of cooling conveyor lines so that each cooling line conveys molds which require variable lengths of time to cool before such molds can be conveyed into a punchout where the cope flask is stripped and the sand mass and castings are pushed up from the drag flask and onto a shakeout which conveys sand to a reclaim system and castings to a processing area where the castings are shot blasted, gates and risers are removed, the castings are inspected, flame washed, welded (as needed), ground, chipped, heat treated and then blast cleaned a second time before final grinding, chipping, gauging, final inspection, assembly and storage. The mold flasks are cleaned, new mold cavities formed therein and are reassembled and then stored in the prepour storage system where their location is recorded by a computer for selective retrieval for the next heat to be poured.

摘要： A flask is filled with a heat resistant filling material, such as sand, to embed therein a pattern of the type which melts down and generates combustible gas when it is heated, a runner connected to the pattern and provided with a sprue and a hollow venting device having an open upper end and a sidewall provided with at least one vent opening. A molten metal is poured into the sprue. The molten metal reaching the pattern through the runner heats the pattern and causes it to melt down and generate gas. The molten metal occupies a cavity formed by the meltdown of the pattern and drives out the gas into the venting device through the filling material and the vent opening. The gas is burned at the upper end of the venting device. Disclosed also is an apparatus which can be used for carrying out the method as hereinabove summarized. The apparatus is useful for either a batch or a continuous type of casting operation.

摘要： For transporting a train (15) of flaskless molds using a simply designed system along a storing, teeming and cooling run or part of a conveyor in a foundry so that the castings are made highly true to size, the forces needed for speeding up and slowing down the mold train (15) are caused to take effect at a desired level on the mold train (15) and, together with the forces acting oppositely to the thermal expansion of the molds (7) within the mold train (15), the forces are transmitted to the full length of the mold train only by the molds (7) themselves.

摘要： 1495966 Foundry plant; moving-mould casting machines OSBORN MFG CORP 10 Dec 1974 [10 Dec 1973] 53398/74 Heading B3F [Also in Division B8] A compact area for cooling and conveying poured moulds is provided by a turntable C, Fig. 1 (shown in detail with moulds B in Fig. 5) which supports at least two circles of moulds (positions 2-23) and has a reciprocable member (beam) 128, Fig. 9, not rotatable with the table beneath it but generally aligned with opposed loading and discharge stations 2 and 19 thereof, Fig. 1, for transferring moulds from one circle to the other and for discharging moulds from the outer circle, the table being indexed to bring moulds into register with the member 128 after each of its mould transfer movements. The moulds may be poured while on the turntable. As shown in Fig. 1 the moulds B are brought by a conveyer A from an automatic moulding machine to a transfer station (position 1 at the end of the reciprocable beam 128). The mould at 2 will be successively indexed to positions 3, 4, 5, 6 and back to 2 before being transferred by the reciprocable beam (between indexing movements) to position 7, to be replaced by the mould from transfer position 1. From position 7 the mould is indexed to alternate positions, 8, 9-of the inner circle of moulds before being passed by way of positions 12, 13 on a fixed framework G, Figs. 5, 9, supporting the turntable, to position 14 in the same circle to go round again. It then passes to position 19 and recircles in outer positions 20, 21-before being discharged by the reciprocable beam 128, as shown, to a second, adjacent, turntable D for a repeat of the circling movements before discharge from position 41. In a further arrangement, one turntable handles forty moulds at a time and in another, Fig. 2 (not shown), the turntable has two levels, one above the other, moulds passing from the upper to the lower level near the axis for further circlings before discharge, there being a reciprocating member extending half-way across each level. The reciprocable beam 128 in Fig. 9 is shown carrying eight moulds B side-by-side, as opposed to the seven to be carried end-to-end for the Fig. 1 arrangement; it corresponds to a turntable (F, Fig. 3, not shown) which is fed with alternate moulds from a storage conveyer, is indexed in clockwise diection and has three intermediate positions (12-14), instead of two on the fixed framework G and is adjacent a transfer table H which receives the discharged mould. The beam 128 is freely positioned within a support member 126 which is reciprocated by an hydraulic cylinder 146, Fig. 9, when the beam is lifted therefrom (to pick up the diametrically-aligned moulds) by bell crank levers (132, Fig. 8, not shown) operated by a fluid cylinder (138). The member 126 bears rails 124 which run between opposed rollers 122. The moulds B are each engaged by four small extensions 142 on the beam 128 when lifted from ears 151 on the fixed framework G and brackets 76, Fig. 5, on the turntable. The turntable, Fig. 5, is indexed on the framework G about a central post 60. A drive member 62 is rotatably mounted on the post and is indexed by a double-acting fluid cylinder 90 pivoted at 92 on a support 88 fixed to the post and on which is also pivoted an arm 84 swingable by the cylinder and bearing a roller 82 to index the member 62 by rolling against a wall of a radial groove 80 in that member. When a vertical cylinder 102 couples the drive member 62 and a support 64 of the turntable (which rides on rollers 68, Fig. 11), radial, downcurving arms 70 of the table, Fig. 5 (and Fig. 6, not shown), can be indexed with the support 64 to index the moulds B. These are borne between horizontal V-shaped extensions 72 at the arm ends which carry the brackets 76 for supporting the moulds in the circles. After each index, the member 62 and support 64 are decoupled and locked against rotation (to the fixed support 68) by a cylinder 112. Mould weights 160, Fig. 11, with openings for register with mould gates and feeders, are mounted by a parallelogram linkage 162, on the rotatable support 64, between the extensions 72 of each alternate pair of adjacent extensions. A projection from the linkage carries a roller 166 which adjacent the loading station rides on the underside of a cam track 168 mounted on the fixed framework G to lift the weight 160 to allow an empty mould to be transferred on to the loading station on the rotatable support 64. During the next indexing movement, the weight 160 is lowered on to the mould, which is then ready for pouring.
