摘要： The invention relates to a method for producing mould parts, especially casting cores, for casting moulds which are used to cast metal melts. A moulding material (F) containing an inorganic binder is loaded into a cavity (12) of a form tool (10) in a mould shooter (1) by means of filling elements such as shot nozzles (8) and shot hoods (6), said cavity defining the shape of the mould part (K) to be produced. Heat is supplied to the moulding material (F) loaded into the form tool (10) over a hardening period, in order to strengthen the moulding material (F) by dehumidifying the same. During the hardening period, at least the filling elements (6,8) of the mould shooter (1) which contain the moulding material (F), which are in a waiting position during said hardening period, and which are simultaneously heated by the radiant heat (W) emitted by the form tool (10), are maintained at a humidity level preventing the strengthening of the moulding material (F). In this way, mould parts for casting moulds can be reliably produced from a moulding material containing an inorganic binder, with reduced fault liability.

摘要： A method for manufacturing an excellent sandmold by adjusting the pressure value or the blowout time of a first compressed air. In the method, foundry sand is squeezed by moving a squeeze means to a pattern plate side after the foundry sand is blown into a molding space demarcated by at least the pattern plate, a flask, and the squeeze means by supplying a second compressed air onto the upper surface of the foundry sand held in a sand blowing device while floatingly moving the foundry sand near a sand blowout port held in the sand blowing device by blowing the first compressed air near the sand blowout port of the sand blowing device positioned above the molding space and holding the foundry sand. The blowout time of the first compressed air can be decreased or increased based on the results obtained by measuring a movement distance to the pattern plate side of the squeeze means when the squeeze of the foundry sand in the molding space is completed and calculating a difference between the measured value and a target value.

摘要： Bei der Anordnung für den Drucklufteinlass- und -auslass an Formmaschinen, insbesondere Kernschießmaschinen, wird die Schießluft aus einem Druckbehälter, der sich in unmittelbarer Nähe des Lufteinlasses befindet, impulsartig auf die Sandsäule im Inneren der Schießeinrichtung geleitet. Eine gleichförmige Druckbeaufschlagung des Kernsandes im Inneren des Schießrohres wird erreicht durch Luftleitkanäle, die unmittelbar in der Wandung des Schießrohres integriert sind und einen Neigungswinkel von 15° bis 45° gegenüber der vertikalen Längsachse des Schießrohres aufweisen. Durch den Verzicht auf gesonderte Luftführungseinrichtungen und die Minimierung der Überströmwege zwischen Druckluftbehälter und Innenraum des Schießrohres wird der Übergangswiderstand der durchströmenden Luft signifikant reduziert. Zugleich sinken die Herstellungskosten der Schießeinrichtung, da die geneigten Luftleitkanäle mit einfachen Mitteln (z. B. Wasserstrahlschneiden) in die Wandung des aus hochfesten Stählen gefertigten Schießrohres eingearbeitet werden können.

摘要： The invention relates to a method for producing casting molds, especially comprised of cores or core packages, whereby molding materials, preferably molding sands, are blown or shot into a molding chamber via a gaseous flow medium, preferably via air, and under a pressure that can be predefined. The shot and resulting solidified mold is then evacuated of air, and the form is opened, upon which the shot mold is subsequently removed. The invention is characterized in that the shooting process and/or the air evacuation process is/are controlled using detected and optionally prepared process parameters according to any predefined specification.
