    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.

    摘要翻译： 本发明涉及用于铸造用于铸造金属熔体的铸模的铸模部件，特别是铸造型芯的制造方法。 通过诸如喷嘴（8）和喷射罩（6）的填充元件将含有无机粘合剂的模制材料（F）装载到模具射出器（1）中的模具工具（10）的空腔（12） ，所述空腔限定待生产的模具部件（K）的形状。 为了通过对模制材料（F）进行除湿来加强模制材料（F），在加热期间将热量供应到装载到模具（10）中的模制材料（F）。 在硬化期间，至少包含模塑材料（F）的模具射出器（1）的填充元件（6,8）在所述硬化期间处于等待位置，并且同时由辐射源 由成型工具（10）发出的热量（W）保持在防止成型材料（F）增强的湿度水平。 以这种方式，铸模的模具部件可以由含有无机粘合剂的模制材料可靠地制造，并且减少了过失。

    摘要： Wendeeinrichtungen (1) für Formkästen (3), insbesondere für den Einsatz in Transportlinien (2,4) automatischer Form- und Gießanlagen, auf welchen die Formkästen (3) verschiebbar sind, um zu den einzelnen Arbeitsstationen gebracht zu werden, so ausgelegt, daß diese die Aufnahme eines oder mehrerer Formkästen zulassen. Diese Wendeeinrichtungen (1) haben eine erste Aufnahmeeinrichtung (6,7) für den bzw. die Formkästen. Um mit derartigen Wendeeinrichtungen auch aus zwei Formkastenhälften bestehende Formkästen wenden zu können, und zwar nicht nur um 180°, sondern auch um 90°, besitzt die Wendeeinrichtung eine zweite parallel zur ersten Aufnahmeeinrichtung verlaufende, jedoch um 90° zur ersten Aufnahmeeinrichtung (8,9) versetzt angeordnete zweite Aufnahmeeinrichtung, welche synchron mit der ersten Aufnahmeeinrichtung angetrieben ist.

    摘要： In a mould (1) with vertical parting surface, each mould cavity (2, 2') is connected through a wide throat with its own after-feeding reservoir (3, 11). When the mould (1) has been poured, a gas pressure is applied through a duct (15, 19) to a metal surface in the after-feeding reservoir (3, 11). This gas pressure is not allowed to exceed the metallostatic pressure in the mould at the surface, at which the pressure is applied, until the metal in the ingate (4) has solidified or the ingate has been blocked in some other way. At the location where the duct (15, 19) opens into the after-feeding reservoir, it is covered by an element (16, 20) that is impermeable for the metal having been poured but permeable for the pressurized gas. When the metal in the ingate (4) has solidified or the ingate has been blocked in some other way, the gas pressure may be increased.
