    摘要: When molding surfaces (50A) of a pair of dies (50) are to be cleaned by air-blowing, air is blown towards the molding surfaces (50A) from blowing nozzles (22A) of a cleaning blowing function portion (22) while a moving body (16) is reciprocatingly moved by driving force of a driving mechanism (18). When a parting agent is to be applied to the molding surfaces (50A) of the pair of dies (50), the mold release agent is jetted out towards the molding surfaces (50A) from spraying nozzles (24A) of a parting agent application function portion (24) while the moving body (16) is reciprocatingly moved by the driving force of the driving mechanism (18). In both of these situations, at the same time as the treatment of the molding surfaces (50A), a cleaning brush (32) reciprocatingly moves together with the moving body (16) and sweeps a device floor surface (12).

    摘要: A method of casting valve seat inserts comprises pouring molten metal into a gating system of a mold plate stack wherein mold plates are located between top and bottom molds wherein the gating system includes a casting header, down-sprue, horizontal sprue, up-sprues, runners, and gates in fluid communication with mold cavities configured to form the valve seat inserts. The method includes filling the mold cavities with the molten metal, and controlling solidification of the molten metal in the mold cavities by means of an outer thermal barrier which retards heat transfer in mold plate material between the mold cavities and an outer periphery of the mold plate stack. An inner thermal barrier can be used to further control solidification of the molten metal. Valve seat inserts produced using the thermal jacket molds can exhibit an improved microhardness distribution which provides improved machining and higher yield.

    摘要: Molding chamber arrangement (1) for a mold-string plant comprising a molding chamber (2) formed by a chamber bottom (3), a chamber ceiling (4) provided with one or more sand filling openings (22) communicating with a sand-feed system (14), two chamber side walls (5), a pressure plate (6) provided with an exchangeable pressure pattern plate having a pressure pattern (8) and being connected to a movement mechanism (9), a swingable plate (10) provided with an exchangeable swing pattern plate having a swing pattern (12) and being mounted for translational and swinging movement in order to open and close the molding chamber (2), allowing the pressure plate (6) to expel the produced molds, and further comprising means (13) for vertically moving the chamber ceiling (4) and sand-feed system (14) in unison, or the chamber bottom (3), or both, relative to the remainder of the molding chamber arrangement (1), thereby changing the height of the molding chamber. By this arrangement, the flexibility of the size of the produced molds, especially the heights of the produced molds, can be adjusted without changing the geometry of the sand feed system above the molding chamber in a time-saving manner.

    摘要: This invention teaches an improved method and apparatus to make metal alloy castings, such as railroad car connector knuckles. One embodiment of the invention comprises a plurality of core mold assembly units contained within a single molding flask, wherein the mold units are filled with molten metal by way of a common runner and riser system. The said core mold assembly elements may be further comprised of a mold and core assembly formed of the same material, such as phenolic urethane impregnated sand, which is used to accurately replicate the desired shape of a final desired product. This invention eliminates the need to carefully gauge a plurality of part patterns within a single mold flask and reduces the potential for loss of parts, for example by cold shunting, by segregating each part to its own mold isolated mold unit. Such a method and apparatus allows a plurality of parts to be cast in a more accurate way, producing less scrap, improving part dimensional stability, and in some cases, reducing the number of cores needed.
