Description
Die Erfindung betrifft ein im Blasverfahren gefertigtes Filtergehäuse aus Kunststoff nach dem Oberbegriff des Patentanspruchs.The invention relates to a filter housing made of plastic according to the preamble, manufactured by the blow molding process of the claim.
Im Blasverfahren hergestellte Filtergehäuse sind z. B. bekannt aus DE-AS 10 80 815 und DE-OS 19 36 333. Jene Filtergehäuse lassen sich allerdings nicht mit gegenüber ihrer Herstellform hinterschnittartig liegenden Räumen ausbilden. Werden solche zur Schließrichtung der Herstel'form hinterschnittartig liegende Räume, wie sie z.B. bei zur Geräuschdämpfung notwendigen Nebenschlußkai.imern jenötigt werden, gewünscht, so müssen diese Räume durch nachträgliches Anformen von Zusatzteilen bzw. Y änden geschaffen werden. Solche Hinterschnitträume, und damit vollständig den Oberbegriff des Patentanspruchs, zeigt schon die DE-OS 20 03 870. Ausgehend von diesem bekannten Filtergehäuse liegt der Erfindung die Aufgabe zugrunde, einen Filtergehäuseaufbau zu schaffen, bei dem solche himerschnittartigen Räume in bzw. an dem Gehäuse von vornherein durch geschickte Verformung des Kunststoffschlauches ausgebildet werden können. Dadurch soll eine möglichst einfache Herstellung von Kunststoffiltergehäusen mit hinterschnittartig angeordneten Räumen erzielt werden.Filter housings produced by the blow molding process are z. B. known from DE-AS 10 80 815 and DE-OS 19 36 333. Those filter housings, however, cannot be used form undercut-like spaces compared to their production form. Will such be the closing direction In the manufacturing form, rooms that are undercut-like, such as those used for noise dampening necessary shunt quays are required, desired, these rooms must be retrospectively Shaping additional parts or Y ands are created. Such undercut dreams, and with it DE-OS 20 03 870 shows the preamble of the claim in full. Based on this known filter housing, the invention is based on the object of a filter housing structure create in which such razor-like spaces in or on the housing from the outset by clever Deformation of the plastic tube can be formed. This is intended to be as simple as possible Manufacture of plastic filter housings can be achieved with undercut-like arranged spaces.
Gelöst wird diese Aufgabe durch die kennzeichnenden Angaben des Patentanspruchs.This problem is solved by the characterizing information of the patent claim.
Die Zeichnung zeigt ein erfindungsgemäß aufgebautes Filtergehäuse eines Ansaugluftfilters für Verbrennungsmotoren schematisch im SchnittThe drawing shows a filter housing constructed according to the invention for an intake air filter for internal combustion engines schematically in section
Das Filtergehäuse besteht aus getrennten Gehäuseteilen 1 und 2, die jedes für sich in einem getrennten Vorgang im Blasverfahren hergestellt werden. Das Gehäuseteil 1 kann man als Filtergehäusetopf und das Gehäuseteil 2 als Filtergehäusedeckel bezeichnen. Sowohl im Gehäuseteil 1 als auch im Gehäuseteil 2 befinden sich als sogenannte Nebenschluß-Dämpfungsräume wirkende Hinterschnitträume 3 und 4. Mit 5 ist ein weiterer als Rohrstutzen dienender Hinterschnittraum bezeichnet und mit 6 ein in das Filtergehäuse gehörender Einsatz. Eine Verbindung zwischen dem Hanptströmungsraum 8 für die Ansaugluft und den Hinterschnitträumen3 erfolgt über z.B. nachträglich gebohrte öffnungen 7.The filter housing consists of separate housing parts 1 and 2, each in a separate one Process can be produced in the blow molding process. The housing part 1 can be used as a filter housing pot and the Designate housing part 2 as the filter housing cover. As well as In the housing part 1 as well as in the housing part 2 there are so-called shunt damping spaces acting undercut spaces 3 and 4. With 5 is another undercut space serving as a pipe socket and with 6 an insert belonging to the filter housing. A connection between the Hemp flow space 8 for the intake air and the undercut spaces 3 takes place via, for example, retrospectively drilled holes 7.
Hergestellt wird das Gehäuseteil 1 folgendermaßen. Ein aufgeblasener Kunststoffschlauch wird in ein in der Zeichnung nicht dargestelltes aus einem Formober- und Formunterteil bestehendes Formwerkzeug für das zu schaffende Gehäuseteil 1 eingebracht Beim Schließen des Formwerkzeuges in Richtung der Pfeile A werden Teile der Kunststoffschlauchwände gegeneinander gebracht und können dabei miteinander verschweißt werden. Die Bereiche, in denen zwei Kunststoffschlauchwände derart .aneinander liegen, sind in der Zeichnung doppelwandig eingetragen. Der Kunststoffschlauch ist bereits vor dem Schließen des Formwerkzeuges aufgeblasen. Nach dem Schließen des Formwerkzeuges erfolgt jedoch durch Zuleitungen in der Form noch ein weiteres Aufblasen der bei dem Gehäuseteil 1 als Hinterschnitträume 3 auszubildenden Nebenschluß-Geräuschdämpfungsräume und des Hin-The housing part 1 is manufactured as follows. An inflated plastic tube is placed in a not shown in the drawing consisting of a Formober- and bottom mold part mold for the to be created housing part 1 when closing of the mold in the direction of arrows A parts are brought, the plastic tube walls against each other and are thereby welded together. The areas in which two plastic tube walls are in such a way .an each other are shown in the drawing as double-walled. The plastic tube is already inflated before the mold is closed. After the mold has been closed, however, the feed lines in the mold are used to inflate the shunt noise-damping spaces to be formed as undercut spaces 3 in the housing part 1 and the backflow.
terschnittraumes 5. Die öffnungen 7 am fertigen Gehäuseteil 1 werden nach der Formgebung im Blasverfahren durch Bohren oder Ausstanzen erzeugt Der den Rohrstutzen bildende Hinterschnittraum 5 ist zum Inneren des Gehäuseteils 1 hin zunächst nach Abschluß des Blasverfahrens noch durch eine Zwischenwand 9 abgetrennt. Diese wird anschließend an die Formgebung des Gehäuseteils 1 mechanisch herausgelöst. Bei dem erfindungsgemäß aufgebauten Gehäuseteil 1 werden alle Wände, die keine hinterschnittartigen Räume umfassen, doppelwandig ausgebildet, während alle übrigen Bereiche einwandig sind.cut space 5. The openings 7 on the finished housing part 1 are produced by drilling or punching after shaping in the blow molding process The undercut space 5 forming the pipe socket is towards the interior of the housing part 1 initially after completion the blow molding process is still separated by a partition 9. This is then followed by the shaping of the housing part 1 mechanically released. In the case of the housing part 1 constructed according to the invention all walls that do not include undercut-like spaces are double-walled, while all other areas are single-walled.
Das Gehäuseteil 2 wird nach dem gleichen Verfahren hergestellt wie das Gehäuseteil 1.The housing part 2 is manufactured using the same method as the housing part 1.
