Abstract
Description
Die Erfindung betrifft einen Verbindungsbereich zweier Kunststoff-Spritzgussteile, insbesondere zweier Halbschalen eines Ansaugkrümmers, mit korrespondierenden, Werkstückkonturen, die in Fügerichtung ineinandergreifen, wobei der Verbindungsbereich zusätzlich eine Vielzahl von quer zur Fügerichtung angeordnete, wenigstens ein Spritzgussteil durchgreifende, von einer Außenoberfläche ausgehende Hohlräume und ein durch Umspritzung hergestelltes Bauteil aufweist, das zumindest aus einer Außenmanschette und einer Vielzahl stoffschlüssig mit der Außenmanschette verbundener, die Hohlräume ausfüllende Elemente gebildet ist.The Invention relates to a connection region of two plastic injection-molded parts, in particular two half-shells of an intake manifold, with corresponding, Workpiece contours, in the joining direction mesh, wherein the connection area additionally a Variety of transverse to the joining direction arranged, at least one injection molded part by cross, of a Outgoing outer surface cavities and a manufactured by encapsulation component, the at least from an outer cuff and a plurality of cohesive with the outer cuff connected, the cavities filling elements is formed.
Aus dem Stand der Technik, beispielsweise der DE-OS 43 29 544 der Filterwerk Mann & Hummel GmbH, ist ein derartiger Verbindungsbereich bekannt. Diese Art der Verbindung zweier Kunststoff-Spritzgussteile durch eine außen angespritzte Manschette sowie durch quer zur Fügerichtung angeordnete Verriegelungselemente erzielt zwar eine stabile Verbindung der Kunststoff-Spritzgussbauteile entgegen der Fügerichtung. Jedoch kann diese Verbindung auf nachteilige Weise bei Auftreten von Querkräften instabil werden. Darüber hinaus wird die Gasdichtigkeit dieser Verbindungsbereiche nach dem Stand der Technik als verbesserungswürdig angesehen.Out the prior art, for example, DE-OS 43 29 544 the filter unit Mann & Hummel GmbH, Such a connection area is known. This type of connection two plastic injection molded parts by an externally molded cuff as well as across the joining direction Although arranged locking elements achieves a stable connection the plastic injection-molded components against the joining direction. However, this can Compound disadvantageously unstable when lateral forces occur become. About that In addition, the gas-tightness of these connection areas after the Prior art considered to be in need of improvement.
Die Aufgabe der Erfindung besteht deshalb darin, einen neuen Verbindungsbereich zweier Kunststoff-Spritzgussteile zu schaffen, der unabhängig von der Art der Belastung zumindest eine zuverlässige mechanische Verbindung der Teile sicherstellt.The The object of the invention is therefore a new connection area to create two plastic injection molded parts, independent of the type of load at least a reliable mechanical connection ensuring the parts.
Die Lösung der Aufgabe ergibt sich aus den Merkmalen des Anspruches 1, insbesondere den Merkmalen des Kennzeichenteils, wonach die im Verbindungsbereich ineinandergreifenden Spritzgussteile zumindest in Teilbereichen gemeinsame Hohlräume ausbilden und dass das durch Umspritzung hergestellte Bauteil unlösbar verriegelnd die gemeinsamen Hohlräume ausfüllt.The solution The object arises from the features of claim 1, in particular the characteristics of the characteristic part, according to which in the connection area interlocking injection molded parts at least in some areas common cavities form and that the component produced by encapsulation indissoluble lock the common cavities fills.
Der erfindungsgemäße Verbindungsbereich hat den wesentlichen Vorteil, dass mit ihm eine zuverlässige mechanische Verriegelung beider ineinandergreifender Spritzgussteile erreicht wird. Dies gilt unabhängig davon, auf welche Art diese Verbindung belastet wird, da durch die gemeinsamen Hohlräume in allen Belastungsfällen ein vollständiger Formschluss zwischen den Spritzgussteilen erreicht wird.Of the has connection area according to the invention the main advantage that with it a reliable mechanical Locking both interlocking injection molded parts achieved becomes. This applies independently of which way this connection is charged, because of the common cavities in all load cases a complete one Positive connection between the injection molded parts is achieved.
Bei einer vorteilhaften Ausführungsform der Erfindung bilden die im Verbindungsbereich ineinandergreifenden Spritzgussteile einen durchgehenden, gemeinsamen Hohlraum aus, der durch ein durch Umspritzung hergestelltes Bauteil ausgefüllt ist.at an advantageous embodiment of the invention form the intermeshing in the connection area Injection molded parts from a continuous, common cavity, the is filled by a manufactured by encapsulation component.
Diese Ausführungsform eines Verbindungsbereiches zeichnet sich dadurch aus, dass durch den durchgehenden, gegebenenfalls umlaufenden, gemeinsamen Hohlraum, der durch ein durch Umspritzung hergestelltes Bauteil ausgefüllt wird, nicht nur eine sehr zuverlässige mechanische Verriegelung der Spritzgussteile erreicht wird, sondern die Verbindung auch gasdicht ausgebildet ist.These embodiment a connection area is characterized by that the continuous, possibly circumferential, common cavity, which is filled by a component produced by encapsulation, not only a very reliable one mechanical locking of the injection molded parts is achieved, but the connection is also gas-tight.
In diesem Zusammenhang ist es bei einer weiteren Ausführungsform vorteilhaft, dass der gemeinsame Hohlraum zur teilweisen Aufnahme des Bauteiles zueinanderweisenden Dichtflächen beider Spritzgussteile gegenüberliegt, wobei durch die Erstellung des den gemeinsamen Hohlraum ausfüllenden Bauteiles die Dichtflächen in einer erhöhten Flächenpressung unterliegen. Bei dieser Ausführungsform wird es durch eine spezielle Geometrie des Verbindungsbereiches und insbesondere durch eine spezielle Anordnung des gemeinsamen Hohlraumes gegenüberliegend den Dichtflächen der Spritzgussteile möglich, die Gasdichtigkeit deutlich zu erhöhen.In This relationship is in another embodiment advantageous that the common cavity for partial absorption the component facing sealing surfaces of both injection molded parts opposite, whereby by the creation of the common cavity filling Components the sealing surfaces in an elevated surface pressure subject. In this embodiment It is characterized by a special geometry of the connection area and in particular by a special arrangement of the common Cavity opposite the sealing surfaces the injection molded parts possible, to increase the gas tightness significantly.
Bei einer bevorzugten Ausführungsform der Erfindung ist das eine Kunststoff-Spritzgussteil mit einer Aufnahmenut und das andere Kunststoff-Spritzgussteil mit einer Feder versehen, die zum Zwecke der Verbindung vollständig in den Aufnahmenut eintaucht.at a preferred embodiment The invention is a plastic injection molded part with a receiving groove and the other plastic injection molded part provided with a spring, for the purpose of connection completely in dips in the receiving groove.
Zum Zwecke der mechanischen und gasdichten Verbindung der vorgenannten Kunststoff-Spritzgussteile kann die Feder des Kunststoff-Spritzgussteiles an ihrem freien Endbereich mit einem verbreiterten Haken ausgebildet sein, wobei im Bereich der Nut unterhalb des Hakens ein mit dem quer zur Fügerichtung verlaufenden Hohlräumen verbundener, durchgehender Hohlraum angeordnet ist, der eine Innenmanschette aufnimmt, die stoffschlüssig mit dem durch Umspritzung hergestellten Bauteil verbunden ist.To the Purposes of the mechanical and gas-tight connection of the aforementioned Plastic injection molded parts can be the spring of the plastic injection molded part formed at its free end with a broadened hook be, wherein in the groove below the hook with the transverse to joining direction extending cavities connected, continuous cavity is arranged, which is an inner sleeve absorbs, the cohesive is connected to the component produced by encapsulation.
Weitere Vorteile der Erfindung ergeben sich aus einem weiteren Unteranspruch sowie aus der Beschreibung eines Ausführungsbeispieles. Es zeigen:Further Advantages of the invention will become apparent from a further dependent claim as well as from the description of an embodiment. Show it:
