Method and device for automating a ci-clo drying under hot air sandmolds

摘要

A process and apparatus for automating a hot-air baking cycle of sand molds. Such process and apparatus make it possible to regulate the hot-air baking or drying speed in a sand mold during a baking cycle. This regulation can be accomplished before casting, and in particular, before low-pressure casting. The process includes dividing the cycle into characteristic phases associated with particular baking parameters. The apparatus includes a calculator assembly for obtaining baking parameters. The invention can be used for the baking of foundry molds, and particularly, foundry molds for aeronautical parts.
