Description
Die Erfindung betrifft eine Positivform zum Vakuumformen einer Nockenplatte mit hohlen Haltenocken aus einer Kunststoffolie, mit von einer Grundplatte in einem Raster hochstehenden, massiven Formnocken, an deren oberem Umfangsrand mindestens zwei nach außen vorstehende Formsegmente angeordnet sind, wobei die Formsegmente durch eine biegeelastische, an den Formnocken befestigte Scheibe gebildet werden mit einer Biegesteifigkeit der Scheibe derart, daß deren Formsegmente ihre nach außen gerichtete Position im wesentlichen beibehalten, wenn eine Kunststoffolie durch Vakuum über die Formnocken gezogen wird, und sich die Formsegmente der Formnocken der Positivform beim Abziehen einer fertig geformten Nockenplatte zur Freigabe der hohlen Haltenocken nach oben biegen.The The invention relates to a positive mold for vacuum forming a cam plate with hollow retaining cams made of a plastic film, with a base plate in a grid upstanding, massive shape cam, on the upper Peripheral edge at least two outwardly projecting mold segments are arranged, wherein the mold segments by a flexurally elastic, formed on the mold cam disc are formed with a bending stiffness the disc such that their Mold segments their outward directionally maintained position substantially when a plastic film through vacuum over the shape cam is pulled, and the shape segments of the shape cam the positive mold when removing a finished shaped cam plate for Turn up the release of the hollow retaining cams.

einer in
Die Herstellung dieser bekannten Positivform und der durch eine Beschädigung erforderliche Austausch der biegeelastischen Scheiben der Form, die die Formsegmente der Formnocken bilden, ist verhältnismäßig aufwendig. Ferner bedingt die Konstruktion der Positivform, daß die Kopffläche der hohlen Haltenocken der gefertigten Nockenplatten Abdrücke des Kopfes des Befestigungsbolzens der Scheibe der Formnocken und Abdrücke der Streifen der Scheibe aufweist.The Production of this known positive mold and the replacement required by a damage the flexurally elastic disks of the mold forming the mold segments of Forming shape cam is relatively expensive. Furthermore, the construction of the positive mold requires that the head surface of the hollow cams of the manufactured cam plates imprints of the Head of the fixing bolt of the shape cam and footprints of the disc Strip of the disc has.
