Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Herstellen eines Spritzgiessteils, in dem ein Einlegeteil integriert ist.The The present invention relates to an apparatus for producing a Injection molding, in which an insert is integrated.

Stand der TechnikState of the art

Bei Spritzgussteilen werden, um z. Bsp. die Festigkeit zu steigern Einlegeteile eingebracht und umspritzt. Vor allen bei automatisierten Einlegeprozessen muss das Vorhandensein und die korrekte Position des Einlegeteils überprüft werden.at Injection molded parts are z. Eg to increase the strength inserts introduced and sprayed. Especially in automated loading processes the presence and the correct position of the insert must be checked become.

Die DE 10 2005 002448 A1 beschreibt ein Verfahren, bei dem der Staudruck eines Fluids an der Formöffnung gemessen wird. Über den Betrag des Staudrucks lassen sich dann Rückschlüsse über die Lage des Einlegeteils ziehen. Dieses Verfahren ist nicht sehr genau und auch nicht bei allen Spritzgiessform- und Einlegeteilgeometrien anwendebar.The DE 10 2005 002448 A1 describes a method in which the back pressure of a fluid is measured at the mold opening. About the amount of dynamic pressure can then draw conclusions about the position of the insert. This method is not very accurate nor applicable to all injection molding and insert geometries.

Lösung der AufgabeSolution of the task

Zur Lösung der Aufgabe führt, dass dass die Vorrichtung einen Sensor aufweist, der das Vorhandensein und/oder die Position des Einlegeteiles detektiert.to Solution of the task that performs that device having a sensor, the presence and / or the position of the insert detected.

Figurenbeschreibungfigure description

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiel sowie anhand der Zeichnung; diese zeigt in ihrer einzigen Figur ein Schema einer geöffneten Spritzgussform.Further Advantages, features and details of the invention will become apparent the following description of a preferred embodiment as well as from the drawing; this shows in her single figure a schematic of an opened injection mold.

Eine Kavität 1 wird durch eine ortsfeste Formplatte 2 und eine bewegliche Formplatte 3 gebildet. In diese Kavität ist ein Einlegeteil 4 eingebracht. Im Ausführungsbeispiel wird das Funktionsprinzip für nur eine Kavität 1 und ein Einlegeteil 4 beschrieben. Natürlich ist auch die Detektion von mehreren Einlegeteilen in einer oder mehreren Kavitäten eines Spritzgiesswerkzeuges denkbar.A cavity 1 is through a stationary mold plate 2 and a movable mold plate 3 educated. In this cavity is an insert 4 brought in. In the exemplary embodiment, the operating principle for only one cavity 1 and an insert 4 described. Of course, the detection of multiple inserts in one or more cavities of an injection mold is conceivable.

Mittels eines Lichtleitersensors 5 der mit einer Auswerteeinheit 6 verbunden ist, wird vor dem eigentlichen Spritzgiessprozesses das Vorhandensein des Einlegeteils 4 und dessen Lage überprüft. Das Detektieren des Einlegeteils 4 durch den Lichtleitersensor 5 unter Weitergabe eines entsprechenden Signals an die Auswerteeinheit 6 ist sowohl bei geöffneter Spritzgussform als auch bei geschlossener Spritzgussform möglich.By means of a fiber optic sensor 5 with an evaluation unit 6 is connected, before the actual injection molding process, the presence of the insert 4 and its location checked. Detecting the insert 4 through the fiber optic sensor 5 passing on a corresponding signal to the evaluation unit 6 is possible both with the injection mold open and with the injection mold closed.

Im Ausführungsbeispiel befindet sich der Lichtleitersensor 5 in der beweglichen Formplatte 3. Alle anderen Möglichkeiten, einen Lichtleitersensor 5 in eine Kavität 1 einer Spritzgussform einzubringen, sind ebenfalls mögliche Ausführungsformen.In the exemplary embodiment, the optical fiber sensor is located 5 in the movable mold plate 3 , All other options, a fiber optic sensor 5 in a cavity 1 an injection mold, are also possible embodiments.

Die Funktionsweise der vorliegenden Erfindung ist folgende:
Das Einlegeteil 4 wird mittels eines Roboters in die Kavität eines Spritzgiesswerkzeuges eingelegt. Dort wird es dann teilweise oder vollständig mit Kunststoffschmelze umspritzt. Durch die Automatisierung des Prozesses durch Roboter muss, vor Beginn des eigentlichen Spritzgiessprozesses eine automatisch Kontrolle des Vorhandenseins und gegebenenfalls der Lage des Spritzgussteils durchgeführt werden. Vor Beginn des Spritzgiessprozesses detektiert der Lichtleitersensor 5 das Vorhandensein und/oder die Position des Einlegeteils 4. Befindet sich das Einlegeteil 4 an der korrekten Position wird das positive Signal des Lichtleitersensors 5 von der Auswerteeinheit 6 an die Maschinensteuerung weitergegeben und der Spritzgiessprozess kann beginnen. Fehlt das Einlegeteil oder befindet es sich nicht an der richtigen Position, wird das negative Signal des Lichtleitersensors 5 von der Auswerteeinheit 6 an eine Maschinensteuerung weitergegeben und der Spritzgiessprozess wird nicht gestartet. Bezugszeichenliste 1 Kavität 2 Ortsfeste Formplatte 3 Bewegliche Formplatte 4 Einlegeteil 5 Lichtleitersensor 6 Auswerteeinheit The operation of the present invention is as follows:
The insert 4 is inserted by means of a robot in the cavity of an injection mold. There it is then partially or completely overmoulded with plastic melt. By automating the process by robots, it is necessary to automatically check the presence and, where appropriate, the position of the injection-molded part before starting the actual injection molding process. Before the start of the injection molding process, the optical fiber sensor detects 5 the presence and / or position of the insert 4 , Is the insert part located? 4 at the correct position becomes the positive signal of the fiber optic sensor 5 from the evaluation unit 6 passed to the machine control and the injection molding process can begin. If the insert is missing or is not in the correct position, the negative signal of the fiber optic sensor becomes missing 5 from the evaluation unit 6 passed to a machine control and the injection molding process is not started.
