Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung von Formen oder Kernen, insbesondere für Gießereizwecke aus einer Mischung aus Sand oder Formstoff und einem wasserlöslichen und/oder Kristallwasser enthaltenden Binder, wobei die Mischung mittels einer Schießeinheit (2) aus dieser in einem Schießvorgang durch mindestens eine an einer Schießplatte (5) angeordnete Ausschussöffnung (7) in ein Form- oder Kernwerkzeug (8) eingeschossen und anschließend ausgehärtet wird. Zur Verhinderung oder Verlangsamung der Aushärtung von Mischungsanteilen im Bereich der Ausschussöffnung (7) wird dieser Bereich zwischen zwei Schießvorgängen mithilfe einer Flüssigkeit feucht gehalten. Weiterhin betrifft die Erfindung auch eine Vorrichtung (1) zur Durchführung des Verfahrens.The invention relates to a method for producing molds or cores, in particular for foundry purposes from a mixture of sand or molding material and a water-soluble and / or water-containing binder, wherein the mixture by means of a shooting unit (2) from this in a shooting process by at least one a shooting plate (5) arranged broke opening (7) is injected into a mold or core tool (8) and then cured. In order to prevent or slow down the hardening of mixture fractions in the area of the reject opening (7), this area is kept wet by means of a liquid between two firings. Furthermore, the invention also relates to a device (1) for carrying out the method.
