摘要： This invention teaches an improved apparatus and method to make metal alloy castings, such as freight car yokes. One embodiment of the invention comprises a core mold assembly unit, wherein the mold unit is filled with molten metal. The core mold assembly units may be further 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.

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.

摘要翻译： 本发明教导了一种改进的制造金属合金铸件的方法和装置，例如铁路车辆连接节点。 本发明的一个实施例包括容纳在单个模制烧瓶内的多个芯模组件单元，其中模具单元通过普通浇道和立管系统填充熔融金属。 所述芯模组件元件还可包括由相同材料形成的模具和芯组件，例如酚醛聚氨酯浸渍砂，其用于精确地复制所需形状的最终所需产品。 本发明消除了在单个模具烧瓶中仔细地测量多个部件图案的需要，通过将每个部件分离到其自己的模具隔离的模具单元上，例如通过冷分流来减少部件损失的可能性。 这种方法和装置允许以更精确的方式铸造多个部件，产生较少的废料，提高部件尺寸的稳定性，并且在一些情况下减少所需的芯的数量。
