Abstract

The feeder pattern with core and envelope ensures withdrawal of core for forming the mould feeder. The feeder pattern shape is not restricted to a spherical shape. The pattern core on the pattern plate can have a cylindrical or pyramid shape with a recess. The core shape ensures high volume with relatively small surface area. The feeder pattern can have a tulip shaped core with a cylindrical envelope. A pneumatic core is formed with the core on integral construction. The core has recess between its base and the pattern plate.

Description

Speisermodell mit einem Kern und einem MantelRiser model with a core and a jacket

(Zusatz zu Patentanmeldung P 28 03 247.5-24) Die Erfindung betrifft ein Speisermodell mit einem Kern und einem Mantel nach Patentanmeldung P 28 03 247.5-24, wobei der Kern entfernbar ist, um so den eigentlichen Speiser zu bilden.(Addition to patent application P 28 03 247.5-24) The invention relates a feeder model with a core and a jacket according to patent application P 28 03 247.5-24, the core being removable so as to form the actual feeder.

Während noch das Speisermodell nach der Hauptanmeldung auf eine Kugelform oder im wesentlichen eine Kugelform abhebt, haben Versuche ergeben, daß merkliche Abweichungen von einer idealen Kugelform, die zwar auch bereits einen etwa kegelstumpfförmigen Fußabschnitt und in diesem eine Einschnurung aufweist, möglich sind und unter Umständen von Vorteil sein können.While still the riser model according to the main application on a spherical shape or essentially a spherical shape stands out, experiments have shown that noticeable Deviations from an ideal spherical shape, which is also already roughly frustoconical Foot section and in this has a constriction, are possible and under certain circumstances can be beneficial.

Es wird daher in erfindungsgemäßer Weiterausgestaltung eines Speisermodelles mit einem Kern und einem Mantel nach Patentanmeldung P 28 03 247.5-24 vorgeschlagen, daß das Speisermodell, mindestens jedoch dessen Kern - ggf. in Abänderung - bei gegenüber dem Modell bzw. der Modellplatte hinterschnittener Ausbildung eine beliebige Form, wie Zylinder- oder Pyramidenform, aufweist, Jedoch auch innerhalb dieses Rahmens besitzt das Speisermodell, mindestens jedoch sein Kern mit Vorteil eine durch großen Rauminhalt bei kleiner Oberfläche bestimmte Form. Durch diese Maßnahmen werden denkbar die Herstellungswie die Einsatzmöglichkeiten eines solchen Speisermodells erweitert.It is therefore in a further development according to the invention of a feeder model proposed with a core and a jacket according to patent application P 28 03 247.5-24, that the riser model, but at least its core - possibly in a modification - at any undercut training compared to the model or the model plate Shape, such as cylinder or pyramid shape, but also within this framework possesses the riser model, but at least its core advantageously has a large one Volume with a small surface certain shape. These measures become conceivable the manufacturing and the application possibilities of such a riser model expanded.

In der Zeichnung ist ein Ausführungsbeispiel schematisch dargestellt, und zwar ein Speisermodell mit einem etwa tulpenförmigen Kern 1 und darüber einem außen etwa zylindrischen Mantel 2, in den bei einstückiger Ausbildung ein Luftdruckkern 21 eingeformt ist, dies bei gegenüber einer Modellplatte m hinterschnittener Ausbildung.In the drawing, an embodiment is shown schematically, namely a feeder model with an approximately tulip-shaped core 1 and above one outside approximately cylindrical shell 2, in which an air pressure core in one-piece design 21 is formed, this with undercut training compared to a model plate m.
