Abstract

Container has attached nuts for fastening, which are held by, or consist of, injection-moulded parts connected to the blown part, pref. by blowing around them or by welding.

Description

Durch Blasen hergestellter Kunststoffteil Die Erfindung bezieht sich auf einen durch Blasen hergestellten Kunststoffteil mit daran angeordneten Anschluß teilen zur Befestigung an maßhaltigen Teilen. Insbesondere bezieht sich die Erfindung auf einen durch Blasen hergestellten Ausgleichsbehälter mit Muttern zur Befestigung an oder in einem metallischen Kraftstoffbehälter. Blown Plastic Part The invention relates to onto a plastic part made by blowing with a connector arranged thereon parts for attachment to dimensionally stable parts. In particular, the invention relates on an expansion tank made by blowing with nuts for fastening on or in a metal fuel tank.

Bei größeren, durch das gegenüber Spritzen billigere Blasen erzeugten Kunststoffteilen hat es sich gezeigt , daß diese Teile sich nach der Fertigstellung gegenüber dem Ursprungsmodell zusammenziehen und bei dann auftretender Wärme erweitern. Wenn nun in einen solchen Kunststoffteil Anschlußtesleo zlB. Muttern, zur Befestigung an einem maßhaltigen Teil eingeblasen sind, macht eine Befestigung des Kunststoffteiles an dem maßhaltigen Teil außerordentliche Mühe, weil die Anschlußteile versetzt siegen. In vielen Fällen ist die Versetzung der Änschlußteilr so groß, d&ß Überhaupt keine Befestigung möglich ist. Da der Kunststoff beimBlasen nicht beeinflußbar ist, macht es sich die Erfindung zur Aufgabe, eine Lösung zu finden, mit der unter Beibchaltung dcr Herstellung des Kunststofteiles durch Blasen trotzdem eine Befestigung der Änschlußteile erzielt wird, mit der Anschlußmaße eingehaRten werden können.Larger bubbles generated by being cheaper than spraying Plastic parts, it has been shown that these parts are after completion contract compared to the original model and expand when the heat then occurs. If now in such a plastic part connection tesleo zlB. Nuts, for fastening are blown in on a dimensionally accurate part, makes an attachment of the plastic part Extraordinary effort on the true-to-size part, because the connecting parts win staggered. In many cases, the displacement of the connecting parts is so large that it is at all no attachment is possible. Since the plastic cannot be influenced when blowing, makes it the task of the invention to find a solution with the additional circuitry The manufacture of the plastic part by blowing nevertheless requires a fastening of the connecting parts is achieved with the connection dimensions can be adhered to.

Erfindungsgemäß wird die gestellte Aufgabe dadurch gelöst, daß die Anschlußteile von einem durch Spritzen erzeugten Kunststoffteil gehalten sind oder aus diesem bestehen, er mit dem durch Blasen erzeugten Kunststoffteil verbn is.According to the invention the object is achieved in that the Connection parts are held by a plastic part produced by injection molding or consist of this, it is connected to the plastic part produced by blowing.

Durch die Erfindung gelingt eine einwandfreie Verbindung, insbesondere auch dann, wenn mehrere Verbindungspunkte vorgesehen sind, denn beim Spritzen von Kunststoffteilen lassen sich gegebene Maße innerhalb verhältnismäßig enger Toleranzen gut einhalten.The invention enables a perfect connection, in particular even if several connection points are provided, because when spraying Plastic parts can be given dimensions within relatively narrow tolerances adhere well.

In vorteilhafter Ausgestaltung der Erfindung kann der durch Spritzen erzeugte Kunststoffteil durch Umbiasen befestigt sein, indem dieser Kunststoffteil in die Glasform eingelegt und dann formschlüssig von dem geblasenen Kunststoffteil festgehalten wird.In an advantageous embodiment of the invention, the can by spraying produced plastic part be attached by umbiasing by this plastic part inserted into the glass mold and then form-fit from the blown plastic part is being held.

Bei kleineren Kunststoffteilen ist es auch möglich, den durch Spritzen erzeugten Kunststoffteil durch eine Schweißung an dem durch Blasen erzeugten Kunststoffteil zu befestigen.In the case of smaller plastic parts, it is also possible to use injection molding produced plastic part by welding on the plastic part produced by blowing to fix.

In der Zeichnung ist der Gegenstand der Erfindung in zwei Ausführungsbespielen dargestellt.In the drawing, the subject of the invention is in two exemplary embodiments shown.

In einem ersten Ausführungsbeispiel nach Fig. 1 besteht die Wandung 1 eines Behälters 2 aus geblasenem Kunststoff. Damit dieser Behälter 2 mit seiner Wandung 1 durch Schrauben mit einer Wandung eines metallischen Behälters verbunden werden kann, sind als Anschlußteile Muttern 3 vorgesehen. Diese Muttern 3 mUssen entsprechend den fUr die Schrauben vorgesehenen Bohrungen in der Wandung des metallischen Behälters einen bestimmten Abstand voneinander einnehmen, der sich weder bei der Herstellung des Behälters 2 noch nach dessen Herstellung verändern darf.In a first embodiment according to FIG. 1, there is a wall 1 of a container 2 made of blown plastic. So that this container 2 with his Wall 1 connected by screws to a wall of a metallic container can be, nuts 3 are provided as connecting parts. These nuts 3 must corresponding to the holes provided for the screws in the wall of the metal The container occupy a certain distance from each other, which is neither in the Manufacture of the container 2 may still change after its manufacture.

Zu diesem Zweck sind die Muttern 3 in einer aus gespritztem Kunststoff bestehenden Platte 4 angeordnet, die durch Umblasen bei der Herstellung des Behälters 2 formschlüssig in der Wandung 1 gehalten ist. Der durch die gespritzte Platte 4 für die Muttern 3 gegebene Abstand voneinander bleibt unabhängig von Dehnungen oder Schrumpfungen der Wandung 1 erhalten, so daß ein Befestigen des Behälters 2 ohne Mühe möglich ist.For this purpose, the nuts 3 are made of injection-molded plastic existing plate 4 arranged by inflation in the manufacture of the container 2 is held positively in the wall 1. The one through the sprayed plate 4 for the nuts 3 given distance from each other remains independent of expansions or Shrinkage of the wall 1 obtained, so that a fastening of the container 2 without Trouble is possible.

Das ist auch bei einem zweiten Ausführungsbeispiel gemäß Fig. 2 der Fall, bei dem die Muttern 3 wiederum ar einer aus gespritztem Kunststoff bestehenden Platte 4 gehalten sid und diese Platte 4 über einem Ausschnitt 5 aus der Wandung 1 eines aus geblasenem Kunststoff bestehenden Behälters 2 durch Schweißung 6 befestigt ist.This is also the case in a second exemplary embodiment according to FIG Case in which the nuts 3 are in turn made of injection-molded plastic Plate 4 held sid and this plate 4 over a cutout 5 from the wall 1 of a container 2 made of blown plastic is attached by welding 6 is.

In der Platte 4 können natürlich auch andere Anschlußteile als Muttern 3 gehalten sein. Ferner ist es möglich die Platte 4 zusätzlich mit Öffnungen, Durchführungen o.dgl. zu versehen, deren Lage sich nicht ändern soll.In the plate 4 can of course other connecting parts than nuts 3 be held. It is also possible for the plate 4 to have additional openings and passages or the like. to be provided whose position should not change.
