Abstract
Description
B e 8 c h r e i b u n g ~Kastenförmiges Kunststoffgehäuse aus Spritzguß" Die Erfindung betrifft ein kastenförmiges Kunststoffgehäuse aus Spritzguß mit an den Innen- und/oder Außenwanden quer zu der Entformung verlaufenden Nuten, Leisten oder dergleichen. B e 8 c h r e i b u n g ~ Box-shaped plastic housing made of injection molding " The invention relates to a box-shaped plastic housing made of injection molding with the inner and / or outer walls transversely to the demolding grooves, strips or similar.
Derartige Gehäuse können z. B. zu dem Zweck hergestellt wer~ den, um beweglichen Teilen eine Führung zu geben. Die der Führung oder auch zur Aufnahme einer endlosen Dichtung diel nenden Nuten, Leisten oder dergleichen verursachen Hinterschnitte an dem Gehäuse, so daß dieses nur mit Hilfe von kom plizierten und mit Schiebern versehenen Werkzeugen unter vielen Fertigungsoperationen hergestellt werden kann. Unter Umständen ist eine Fertigung aus zwei Einzelteilen erforderlich, die anschließend zusammengesetzt werden müssen.Such housing can, for. B. are manufactured for the purpose, to give a guide to moving parts. The leadership or the recording cause an endless seal diel Nenden grooves, strips or the like Undercuts on the housing, so that this only with the help of com plicated and slider tools are manufactured under many manufacturing operations can be. It may be necessary to manufacture two individual parts, which then have to be put together.
Diese Nachteile vermeidet die Erfindung dadurch, daß das Gehäuse aus zwei symmetrischen Gehäusehälften besteht, die durch ein angespritztes Filmscharnier miteinander verbunden sind.The invention avoids these disadvantages in that the housing consists of two symmetrical halves of the housing, which are secured by an injection-molded film hinge are connected to each other.
Das Filmscharnier ermöglicht eine Herstellung des Gehäuses im aufgeklappten Zustand. Dadurch können die zusammenhängenden Gehäusehälften mit innen- und außenliegenden Hinterschnitten in einfachen und billigen Werkzeugen ohne Schieber gefertigt werden. Die Entformung kann durch einfaches Auseinanderziehen der Formhälften erfolgen.The film hinge enables the housing to be produced in the unfolded position State. This allows the connected housing halves with internal and external Undercuts can be made in simple and cheap tools without a slide. Demolding can be done by simply pulling the mold halves apart.
Um das Gehäuse im zusammengeklappten Zustand, also in der Gebrauchsform zu halten, weisen zweckmäßig die Gehäusehälften einander zugeordnete Befestigungsmittel auf, die die Trennfuge des Gehäuses weiter von dem Filmscharnier entfernt überbrücken.To the case in the folded state, so in the form of use To hold, the housing halves expediently have fastening means assigned to one another that bridge the parting line of the housing further away from the film hinge.
Das Befestigungsmittel kann vorteilhaft in Form eines am Rande der einen Gehäusehälfte vorgesehenen Stiftes vorhanden sein, der die Trennfuge des Gehäuses senkrecht überragt und durch eine Öffnung der anderen Gehäusehälfte eng umschlossen ist.The fastening means can advantageously be in the form of an on the edge of the a housing half provided pin be present, which the parting line of the housing protrudes vertically and is tightly enclosed by an opening in the other half of the housing is.
Falls ein spritzwassergeschütztes Gehäuse verlangt wird, hat es sich als besonders vorteilhaft erwi.sen, die gegeneinander anliegenden Ränder der Gehäusehälften eir Feder und Nut auslubilden.If a splash-proof housing is required, that's it The edges of the housing halves which lie against one another are particularly advantageous Form a tongue and groove.
Im folgenden wird die Erfindung anhand eine in der Zeichnung schematisch dargestellten Ausfuhrungubeispiels beschrieben.In the following the invention is illustrated schematically with reference to one in the drawing illustrated exemplary embodiment described.
Es zeigen: Fig. 1 ein wannenförmiges Kunststoffteil in Seitenansicht und Fig. 2 einen Schnitt nach der Linie II-II der Fig. 1.They show: FIG. 1 a tub-shaped plastic part in side view and FIG. 2 shows a section along the line II-II in FIG. 1.
Mit 1 ist ein wannenförmiges Gehäuse aus Kunststoff bezeichnet, das zum Einsetzen in ein Gegenlager und zum Führen eines flachen Schiebers bestimmt ist. Die Verankerung des Gehäuses 1 erfolgt durch außenliegende, widerhakenförmig ausgebildete Warzen 2, während zur Führung des Schiebers Längsnuten 3 dienen, die in die Innenwandung des Gehäuses 1 eingelassen sind und in ein Fenster 4 in der Rückwand 5 auslaufen, um den Schieber betätigen zu können. Eine am Gehäuse 1 außen umlaufende Nut 6 ist noch für die Aufnahme einer Dichtung vorgesehen.With a tub-shaped housing made of plastic is referred to, which intended for insertion in a counter bearing and for guiding a flat slide is. The anchoring of the housing 1 takes place by external, barb-shaped trained warts 2, while longitudinal grooves 3 are used to guide the slide, the are embedded in the inner wall of the housing 1 and in a window 4 in the Back wall 5 run out in order to be able to operate the slide. One on the outside of the housing 1 circumferential groove 6 is also provided for receiving a seal.
Das Gehäuse 1 besteht aus zwei symmetrischen Qehäusehälften 7 und 7a die durch ein Filmscharnier 8 an einer Längsseite miteinander verbunden und daher auseinanderzuklappen sind, wie dies strichpunktiert in Fig. 2 dargestellt ist. Im zusammengeklappten Zustand des Gehäuses 1 dringen zwei in der Trennfuge 9 an der einen Gehäusehälfte 7 vorgesehene Stifte 10 in enge Bohrungen 11 der anderen Gehäusehälfte 7a ein, so daß das Gehäuse 1 zus ammengehalten bleibt.The housing 1 consists of two symmetrical Qehäusehälften 7 and 7a connected to one another by a film hinge 8 on one long side and therefore are to be unfolded, as shown in phantom in FIG. in the folded state of the housing 1 penetrate two in the parting line 9 on the a housing half 7 provided pins 10 in narrow bores 11 of the other housing half 7a, so that the housing 1 is kept together.
