Embodiment Construction

[0039] figure 1 A tool 1 is shown for shaking out clusters 2 used to produce parts by lost wax casting methods or investment casting techniques.

[0040] The tufts 2 are captured in the shell 3, which is intended to be destroyed during the shakeout step. The shell 3 is pre-manufactured from a refractory material forming a mold. In this example, the refractory material is ceramic. exist figure 1 , the tuft 2 with the shell 3 comprises a crown 4 and a central column 5 extending from the crown 4 along a longitudinal axis Z. The crown and central column are coaxial. The crown 4 includes a pouring cup 7 through which molten metal is poured. The casting cup 7 is coaxial with the central column 5 . The shell 3 also includes a number of cavities (not shown) intended to form metal parts. These cavities are arranged around the central column 5 and on the perimeter of the crown 4 to form the clusters 2 . A conduit 8 connects the pouring cup 7 to the cavity, whereby the conduit co...

Abstract

The invention relates to a tool (1) for shaking out clusters (2) of foundry castings produced by lost wax casting, the tool comprising: a frame (10) extending along a first axis (Z), a support means (13) connected to the frame (10) and intended to support the clusters (2) of parts, the support means (13) relative to the frame (13) about a second axis (Y) perpendicular to the first axis (Z) 10) Rotationally moving, and,-drive device (23, 24) configured to be remotely actuated and to be driven by jets of high-pressure fluid (F) jets intended to remove mold residues by impact The support device (13) is driven in rotation about the second axis (Y) under the action of an applied pressure greater than or equal to a certain pressure value.

Description

technical field [0001] The present invention relates to the field of lost wax casting using lost wax casting technology to produce metal foundry castings. In particular, the present invention relates to a tooling for the casting of clusters of cast castings from metals produced by lost wax casting, in particular a tooling to shake out sand from residual moulds. Background technique [0002] Lost wax casting techniques or investment casting techniques are particularly well known for making parts with complex shapes, such as metal parts for turbine engines. This technique involves using a model made of wax or similar material to produce a mould called a shell, and once the wax has been removed in various ways, the mould forms a cavity which is then supplied with molten metal and fed by the mould Molten metal filling. After cooling and hardening of the metal, the mold shell is broken to reveal the metal part in the form of a model. [0003] In one example, multiple wax model...
