Definitions
- the invention relates to a method for casting molded parts.
- the invention relates generally to the casting of molded parts, i.e. on the foundry technology.
- foundry cores and / or molds are usually produced from separate parts, brought together and connected to one another to form a mold or a core package or mold package.
- mold / core packages are then filled with molten metal to produce, for example, a metallic workpiece, with the mold / core packages to be filled with molten metal passing through the production line in a row in series production.
- molded parts have been cast in a mold, which in turn consists of cores or a core package. After the mold has been fired and completed, it is incorporated into a further mold or environment made of core sand in order to be able to guarantee the required mechanical stability.
- the molding sand forming the mold / core package must then be removed from the cast molding. Due to a binding agent, the molding sand has to be disposed of or recycled in a special way. The effort involved is considerable.
- the method known from the prior art requires a considerable supply of energy in the form of the heat introduced into the mold package with the melt, which has so far been more or less lost via the cooling process.
- additional energy had to be used to anneal the binder and thus to recycle the molding / grain sand.
- the present invention is based on the object of designing and developing the generic method discussed above in such a way that the energy used for casting is used in the best possible way.
- Provision of the mold or a core package made up of individual molds and / or cores of molding sand,
- the process heat can be used to burn the organic or inorganic binder in the molding sand, so that special recycling measures are then no longer necessary. Special disposal of the molding sand as special waste is then no longer necessary if you do not want to continue using the molding sand.
- the process heat can also be used to heat the molded part.
- the molded part could be cooled in a particularly advantageous manner in a controlled manner, the thermal insulation around the actual core package being of particular importance.
- the flue gases generated during the combustion of the binder are retained within the device for heat insulation. They can be vacuumed off at the end of the insulation process. The concentrated presence of the harmful gases makes it considerably easier to dispose of or destroy them, which considerably simplifies the process.
