Abstract: In a mould assembly for multiple castings each mould is fed from a source of molten metal through a thin slit the width of which lies in the range 1.25 mm to 0.25 mm. The cast articles can be easily removed from the runner and riser system after casting without a machining operation so that the casting moulds can be packed closer together and more castings can be produced from each mould assembly. The thin slit also acts as a filter. A particular mould assembly seen in FIG. 2 is cylindrical and comprises a plurality of wedge-shaped mould segments 2 having mould cavities 4 in abutting faces. A central runner passage 6 is formed when the mould segments are assembled and the metal flows into the mould cavities through narrow slits 10 in one edge of each mould. After casting and removal of the mould the narrow flashing formed in the slits can be easily broken to remove the cast articles from the metal formed in the central runner passage.
Abstract translation: 在用于多个铸件的模具组件中，每个模具从熔融金属源通过宽度为1.25mm至0.25mm的薄狭缝进给。 在不进行加工操作的铸造之后，铸造制品可以容易地从流道和立管系统中移除，使得铸模可以被更紧密地包装在一起，并且可以从每个模具组件产生更多的铸件。 薄缝也充当过滤器。 图1中所示的特定模具组件。 图2是圆柱形的并且包括多个楔形模具段2，其具有邻接面中的模腔4。 当模具段被组装并且金属通过每个模具的一个边缘中的狭窄狭缝10流入模具腔体时形成中心流道通道6。 在铸造和移除模具之后，可以容易地破裂形成在狭缝中的窄闪光，以从铸造中心流道中形成的金属去除铸造制品。
