<p>The production of a mold for the production of components of a gas turbine/turbine blade/heat shield element, comprises producing a recess (46) in a surface (58) of a wax model (43) of a component to be produced by the mold in an intermediate step, introducing a shaped material into a part of the recess to produce a part of a hole of the component during molding, completely filling the recess with a material, which results projection of the mold, hardening the material in the recess and connecting the hardened material with an internal wall (25) or an external wall of the mold. The production of a mold for the production of components of a gas turbine or turbine blade or heat shield element, comprises producing a recess (46) in a surface (58) of a wax model (43) of the component to be produced by the mold in an intermediate step, introducing a shaped material into a part of the recess to produce a part of a hole of the component during molding, completely filling the recess with a material, which results projection of the mold, hardening the material in the recess, connecting the hardened material with an internal wall (25) or an external wall of the mold, bringing the recess into the model before a wall (44) is mounted, partially and continuously extending the recess by a wall of the model and bringing the external wall in connection with the model, which is removed, so that the mold results. The mold consists of a core. The recess is filled with material during mounting the internal wall, the core or the external wall. The internal wall or the core is already arranged in the model, when the recesses are produced. The recess is an angular hole.</p> |
