<p>The apparatus is intended for decoring, that is for removing the core clay from the cavities of hollow metal castings of elongate form with end apertures. It includes a fixture (26) provided with positioning, support and retaining means (46, 52, 54, 56, 58, 60) for the casting (C) to be decored, means (42) for vibrating the casting and blower means (62). This fixture (26) is supported by an assembly (14, 24) which is rotatable about a horizontal axis (A) and is so arranged that, with the casting (C) held on the fixture (26), the axis of alignment (E) of its two end apertures is at an angle ( beta ) other than zero to the horizontal axis (A) of rotation of the assembly (14, 24).</p> |
