Abstract

Die Erfindung bezieht sich auf eine Kernbüchse (6, 7) für die pneumatische Herstellung von Gießkernen aus Sand, mit innerhalb der Kernbüchse (6, 7) angeordneten und an deren Wandung anliegenden, nach erfolgter Füllung der Kernbüchse (6, 7) zu entfernenden Losteilen (8).
Das bei den bekannten Kernbüchsen dieser Art vorhan­ dene Problem des Übertritts von Kernsand an Schlitzen, die sich zwischen der Wandung der Kernbüchse (6, 7) und den Losteilen (8) ergeben, und die hierdurch verursachten Feh­ ler am Kern vermeidet die Erfindung durch eine oder meh­ rere aus einem elastischen Material bestehende Dichtun­ gen (9) für die zwischen der Wandung der Kernbüchse (6, 7) und den Anlageflächen der Losteile (8) bestehenden Nahtstellen.
