1,124,825. Centrifugal casting. ZIMMERMANN & JANSEN G.m.b.H., and SIEGLANDER KUPFERWERKE G.m.b.H. 1 Sept., 1965 [1 Sept., 1964], No. 37414/65. Heading B3F. A centrifugal casting mould for casting'articles of large surface area and small height such as a damper-plate. is adapted for rotation about an axis and comprises two separable mould parts 1 and 2 defining a cavity extending substantially perpendicular to the axis 7 of rotation and a core 4<SP>1</SP> located in the cavity to define with the cavity wall a space wholly surrounding the core and communicating with an ingate 6, the diameter of the ingate being substantially equal to the distance between adjacent parallel walls of the core and the cavity. The core is supported in the mould by carriers denoted by their centre lines 5 and which extend into the core and through the wall of the mould. The mould halves are each provided with vent passages 11 which communicate with an annular duct 10 to facilitate the removal of gases generated during the casting operation. The mould halves may be wholly or partly permanent shell moulds. The core remains in the finished casting when solidified. |
