Abstract (en)

[origin: DE19956877C1] Production of a cast part comprises using a two-piece tool (6) having halves (7, 8) and a slanted parting plane (9) between the two halves to produce parallel functional surfaces (4, 5), the tool filling the intermediate space between the functional surfaces; and removing the two halves in opposing directions and from the intermediate space after casting. Preferred Features: The tool halves are removed from the intermediate space at an angle between zero and the angle of the parting plane between the tool halves.

Abstract (de)

Um mit einfachen Mitteln kostengünstige Gussteile mit planparallelen Funktionsflächen herstellen zu können, wird ein zweigeteiltes Werkzeug (6) mit zwei aneinander liegenden Werkzeughälften (7, 8) und einer schräg verlaufenden Trennebene (9) zwischen den Werkzeughälften (7, 8) verwendet, wobei nach Abschluss des Gießvorgangs die beiden Werkzeughälften (7, 8) in entgegengesetzten Richtungen und jeweils winklig zu den Funktionsflächen entfernt werden. <IMAGE>
