Description
Die Erfindung betrifft eine Angußvorrichtung für Spritzgießwerkzeuge gemäß dem Oberbegriff des Schutzanspruchs 1.The The invention relates to a sprue device for injection molding tools according to the generic term of the protection claim 1.
In der Kunststoffspritzgießtechnik werden Spritzgießwerkzeuge verwendet, in die die Form des Spritzgußteils eingearbeitet ist. Dazu werden meist zwei zusammenfügbare Werkzeugplatten vorgesehen, in denen die Aussparungen enthalten sind, in die die eigentlichen Formkörper einfügbar sind. Nach dem Erkalten der Spritzgießmasse sind diese Platten voneinander lösbar, so daß das Spritzgußteil herausgelöst werden kann. Zum Einleiten der erhitzten Spritzgußmasse in den Formhohlraum sind in den Werkzeugplatten Angußkanäle eingearbeitet, an deren Ende sich die sogenannten Anschnitte befinden, an den die Kanäle in den Formhohlraum münden. Für die unterschiedlichen Anforderungen an die Spritzgießtechnik und die Gießteile sind verschiedene Ausführungen von Längen und Querschnitten der Angußkanäle sowie verschiedene Arten und Lagen des Anschnitts gebräuchlich.In the plastic injection molding technique become injection molds used, in which the shape of the injection molded part is incorporated. To are usually two joinable Tool plates provided in which contain the recesses are, in which the actual moldings are inserted. After cooling the injection molding compound these plates are detachable from each other, so that injection molding leached can be. For introducing the heated injection molding compound in the mold cavity are incorporated in the mold plates runner, At the end of which are the so-called gates, to which the channels open into the mold cavity. For the different requirements for the injection molding and casting are different versions of lengths and cross sections of the runners as well different types and locations of bleed in use.

Der Erfindung liegt deshalb die Aufgabe zugrunde, den Anguß für Spritzgießwerkzeuge der eingangs genannten Art so zu verbessern, dass auf einfache Art und Weise lange Nachbearbeitungszeiten an den Angußvorrichtungen vermieden werden.Of the The invention is therefore based on the object, the gate for injection molds to improve the type mentioned so that in a simple way and long post-processing times on the gate devices be avoided.
Diese Aufgabe wird durch die im Schutzanspruch 1 angegebene Erfindung gelöst. Weiterbildungen und vorteilhafte Ausführungsbeispiele der Erfindung sind in den Unteransprüchen angegeben. Die Erfindung hat den Vorteil, dass durch Austausch der vorgefertigten Fertigeinsätze mit unterschiedlichen Angußkanälen und/oder Anschnitten zeitsparend ein optimales Einspritzergebnis gefunden werden kann.These The object is achieved by the protection specified in claim 1 invention solved. Further developments and advantageous embodiments of the invention are in the subclaims specified. The invention has the advantage that by replacing the prefabricated ready inserts with different runners and / or Gates save time an optimal injection result found can be.
Weiterhin ist auch vorteilhaft, dass durch den Austausch der vorgefertigten Einsätze ein durch Abnutzung verschlissener Angußkanal und/oder Anschnitt erneuert werden kann.Farther is also advantageous that by replacing the prefabricated Calls renewed by wear worn runner and / or bleed can be.
In einer bevorzugten Ausführungsform, bei der der Angußkanal direkt an der Kante des Fertigeinsatzes in den Formhohlkörper mündet, entsteht in vorteilhafter Weise ein Anschnitt, der zu einem sauberen Abriss des Spritzgußteils führt, der keiner Nachbearbeitung mehr bedarf. Dadurch wird gleichzeitig ein düsenartiger Materialaustritt erzeugt, der übermäßigen Verschleiß an gegenüberliegenden Formflächen verhindert, so dass auch Spritzgußteile mit geringer Wanddicke vorteilhaft herstellbar sind.In a preferred embodiment, at the runner opens directly at the edge of the finished insert in the hollow body, arises advantageously a bleed leading to a clean break of the injection-molded part leads, which no longer requires post-processing. This will be simultaneous a nozzle-like Material leakage generated, which prevents excessive wear on opposite mold surfaces, so that also injection molded parts with small wall thickness can be produced advantageously.
Die Erfindung wird anhand eines Ausführungsbeispiels, das in der Zeichnung dargestellt ist, näher erläutert. Es zeigen:The Invention is based on an embodiment, which is shown in the drawing, explained in more detail. Show it:

In einer anderen Ausführungsform sind auch Angußeinsätze herstellbar, die mehrere Anschnitte aufweisen, wobei die Angußkanäle doppelseitig kreuz- oder sternweise verlaufen. Vorteilhafterweise ist dann eine zentrale Einlaufstelle vorgesehen, wobei die Anschnitte in einer oder auch verschiedenen Formhohlkörpern enden.In another embodiment are also Angußeinsätze produce, have the multiple gates, the runners on both sides cross- or run in a star pattern. Advantageously, then is a central Enema provided, the gates in one or even various mold cavities end up.
