Abstract
Description
Die Erfindung betrifft ein Verfahren zum zumindest teilweisen Umspritzen von einem Teil eines Einlegeteils in einer Kavität, welche von einer Mehrzahl von Formwandteilen gebildet oder verschlossen wird, sowie eine Vorrichtung hierfür.The The invention relates to a method for at least partial encapsulation from a part of an insert in a cavity, which of a plurality formed or closed by mold wall parts, as well as a device therefor.
Bei
der industriellen Produktion einer Vielzahl von Teilen ist es notwendig,
diese mit einem Kunststoffteil zu versehen, was beispielsweise durch
ein Anspritzen oder Umspritzen eines Teils des Einlegeteils geschieht.
Nur beispielhaft wird auf die
In der Regel besteht das Einlegeteil selbst aus einem anderen Material, als Kunststoff. Beispielsweise kann dieses Material ein Metall sein, wobei das Einlegeteil im Stanz- oder Feinschnittverfahren hergestellt wird. Hierbei ist es aber unumgänglich, dass das Einlegeteil im Laufe des Produktionsprozesses seine geometrische Form ändert und dass insbesondere die Einlegeteile einer ganzen Stanzserie unterschiedlich zueinander sein können. Werden diese Einlegeteile in eine Form zum Umspritzen eingelegt, so kommt es entweder zu einem Verbiegen des Teils im Werkzeug, was unerwünscht ist, oder aber es bilden sich in der Form Spalten, durch die Kunststoff nach aussen dringen kann. Dies bedeutet, dass derartig hergestellte bzw. umgespritzte Einlegeteile anschliessend von Hand verputzt werden müssen. Dies ist ebenso teuer, wie ein vorheriges mechanisches Bearbeiten der Einlegeteile, damit sie möglichst immer die gleiche geometrische Form aufweisen, was schlussendlich doch nicht gelingt.In usually the insert itself consists of a different material, as plastic. For example, this material may be a metal, wherein the insert produced by punching or fine cutting process becomes. But it is imperative that the insert changes its geometric shape during the production process and that in particular the inserts of a whole punching series different can be to each other. If these inserts are inserted into a mold for encapsulation, so it comes either to a bending of the part in the tool, which undesirable is, or else form in the form of columns, through the plastic can penetrate to the outside. This means that produced in this way or injection-molded inserts are then plastered by hand have to. This is as expensive as a previous mechanical processing the inserts so they as possible always have the same geometric shape, ultimately but not succeed.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der o.g. Art zu schaffen, welche den geometrischen Ungenauigkeiten von Einlegeteilen Rechnung trägt.Of the The present invention is based on the object, a method and a device of the above-mentioned. Kind of creating the geometric Inaccuracies of inserts takes into account.
LÖSUNG DER AUFGABESOLUTION OF THE TASK
Zur Lösung dieser Aufgabe führt, dass sich zumindest ein Formwandteil geometrischen Änderungen des Einlegeteils automatisch anpasst.to solution performs this task, that at least one mold wall part geometric changes of Automatically adapts the insert.
D.h., die Kavität ist nicht mehr starr festgelegt, so dass das Einlegeteil auf die Kavität ausgerichtet werden muss, sondern die Formwandteile passen sich dem Einlegeteil an. Hierdurch wird das Einlegeteil weder verformt noch verschoben, so dass sich keine Spalten bilden.that is, the cavity is no longer rigidly fixed, so that the insert on the cavity must be aligned, but the mold wall parts adapt to the insert. As a result, the insert is neither deformed still shifted, so that no columns form.
Bevorzugt wirken zwei Formwandteile, die sich gegenüberliegen, zusammen, so dass immer ein Formwandteil einer Ungenauigkeit ausweicht, während das andere Formwandteil dieser Ungenauigkeit nachläuft.Prefers act two mold wall parts that face each other, together, so that always avoids a mold wall part of an inaccuracy while the another mold wall part of this inaccuracy trailing.
Dieses automatische Anpassen geschieht bevorzugt dadurch, dass die Formwandteile mit Druck beaufschlagt und die Druckentwicklung beobachtet wird. In dem Augenblick, in dem das Formwandteil auf das Einlegeteil auftrifft, erhöht sich der Druck, so dass die Druckbeaufschlagung sofort beendet werden kann.This Automatic adjustment is preferably done by the mold wall parts pressurized and the pressure development is observed. At the moment in which the mold wall part impinges on the insert, elevated the pressure so that the pressurization is stopped immediately can.
Als Druckgeber sind insbesondere hydraulische oder pneumatische Zylinder denkbar. Im Rahmen der Erfindung sollen aber auch Kraftspeicher, wie beispielsweise Federelemente oder elastische Puffer liegen. Gerade die elastischen Puffer benötigen keinerlei weitere Wartung, so dass eine Kostenreduktion erfolgen kann.When Pressure transmitters are in particular hydraulic or pneumatic cylinders conceivable. In the context of the invention, but also energy storage, such as spring elements or elastic buffers are. Especially the elastic buffers need no further maintenance, so that a cost reduction can take place.
Mit der vorliegenden Erfindung kann allen geometrischen Änderungen eines Einlegeteils Rechnung getragen werden, sei es, dass es verbogen ist, oder dass die Materialstärke wechselt. Spalten in der Form werden zuverlässig vermieden, so dass ein nachträgliches Putzen oder ein vorheriges mechanisches Bearbeiten des Einlegeteils nicht notwendig ist.With The present invention is capable of all geometric changes of an insert, whether it be bent is, or that the material thickness replaced. Columns in the mold are reliably avoided, allowing a subsequent Cleaning or prior mechanical processing of the insert is not necessary.
