Abstract

A tool, especially for producing molding cores. The tool is disposed in a casting apparatus and is provided with first half-shells (13, 15) and second half-shells (14, 16). Two parting planes are provided, and two casting units are formed from the first and second half-shells. These parting planes are situated one behind the other in the direction of movement of the two casting units.

Description

Die Erfindung betrifft ein Werkzeug insbesondere zum Herstellen von Kernen, welches in einer Gießeinrichtung angeordnet ist und wobei das Werkzeug erste Gießhalbschalen und zweite Gießhalbschalen aufweist.The invention relates to a tool, in particular for producing cores, which is arranged in a casting device and wherein the tool is first Has half-shells and second half-shells.

Solche Werkzeuge werden beispielsweise in der sogenannten Lost-Core-Technik verwendet. Bei dieser Technik werden Kerne aus einer niedrig schmelzenden Metallegierung im Niederdruckverfahren in eine mehrfach teilbare Kokile gegossen. Diese Kerne werden anschließend in einer Kunststoff-Spritzgießmaschine eingelegt. Die Fertigung eines Kunststoffteils erfolgt durch Umspritzen des Kerns im Spritzgießwerkzeug. Nach dem Abkühlen des umspritzten Kerns erfolgt das Ausschmelzen durch die Einbringung entsprechender Schmelzwärme. Hierzu wird das Kunststoffteil mit dem Kern in ein temperiertes Bad getaucht und durch induktive Unterstützung ein gleichmäßiges Schmelzen des Kerns erreicht. Die Fertigung des Kems erfolgt in einer horizontal angeordneten Gießeinrichung. Da der Kern eine relativ hohe Masse aufweist, ist eine lange Abkühlphase erforderlich. Dies bedeutet, daß die Taktzeiten im wesentlichen von den Abkühlzeiten beeinflußt werden und unter Umständen wesentlich länger sind als die nachfolgenden Taktzeiten beim Umspritzen des Kerns mit thermoplastischem Kunststoff.Such tools are used, for example, in the so-called lost core technology used. With this technique, cores are made from a low melting metal alloy in a low pressure process in a multiple Divisible Kokile poured. These cores are then in one Plastic injection molding machine inserted. The production of a plastic part is done by overmolding the core in the injection mold. After this When the overmolded core cools down, it melts out Introduction of appropriate heat of fusion. For this, the plastic part with the core immersed in a tempered bath and by inductive support the core melts evenly. The manufacture of the core takes place in a horizontally arranged pouring device. Because the core is one has a relatively high mass, a long cooling phase is required. This means that the cycle times are essentially influenced by the cooling times and may be significantly longer than the following Cycle times when molding the core with thermoplastic.

Deshalb wurden bisher mehrere Kerngießmaschinen benötigt, damit die Produktion einer bestimmten Anzahl von Kernen innerhalb einer bestimmten Zeit möglich war.For this reason, several core casting machines have so far been required for production a certain number of cores within a certain time was possible.

Die US 4,399,859 beschreibt ein Werkzeug mit zwei Gießeinheiten, die parallel arbeiten. Die Einheiten lassen sich gemeinsam öffnen bzw. schließen. Hierzu sind die Werkzeuge auf entsprechenden Führungen angeordnet Zum Entformen werden sowohl die außeren als auch die inneren Kernhälften auseinander geschoben und die hergestellten Teile werden über Auswerfer aus dem Werkzeug entfernt.The US 4,399,859 describes a tool with two casting units that run in parallel work. The units can be opened and closed together. For this the tools are arranged on appropriate guides for demoulding the outer as well as the inner core halves separate pushed and the manufactured parts are ejected from the tool away.

Der Erfindung liegt die Aufgabe zugrunde, ein Werkzeug, insbesondere zum Herstellen von Kernen zu schaffen, mit welchen kürzere Zykluszeiten erreicht werden und materialsparende Angüsse schafft.The invention has for its object a tool, in particular for Manufacturing cores to create shorter cycle times and creates material-saving sprues.

Diese Aufgabe wird nach den Merkmalen des Anspruches 1 gelöst.This object is achieved according to the features of claim 1.

Der wesentliche Vorteil dieser Erfindung liegt darin, daß damit in einer einzigen Kerngießmaschine parallel mindestens zwei Kerne gleichzeitig gegossen werden können und damit die Taktzeit halbiert werden. Damit die Kerne von einem Greifer entnommen werden können, wird gemäß der Erfindung das Werkzeug nach dem Gießen derart verfahren, daß die Gießkeme auf beiden Seiten freigefahren sind und entnommen werden können.The main advantage of this invention is that it is in a single Core casting machine can be cast in parallel at least two cores at the same time can and thus the cycle time can be halved. So that the cores of one According to the invention, the tool can be removed from the gripper after casting, proceed in such a way that the pouring cores are cleared on both sides are and can be removed.

In einer Ausgestaltung der Erfindung wird vorgeschlagen, die jeweiligen sich parallel bewegenden Gießhalbschalen über Verbindungsstangen zu koppeln. Die Krafteinwirkung erfolgt somit über diese Verbindungsstangen, wobei evtl. ein toleranzausgleichendes Federpaket vorgesehen sein kann. Gemäß einer weiteren Ausgestaltung der Erfindung ist jede Gießhalbschale mit einem oder mehreren Auswerfern ausgerüstet. Die Kemgießmaschine kann mit mehreren nebeneinander angeordneten Gießeinheiten bestückt sein. Dadurch lassen sich beispielsweise 4 oder 6 Kerne in einem Arbeitszyklus herstellen.In one embodiment of the invention, it is proposed that each to connect parallel moving half-shells via connecting rods. The force is thus applied via these connecting rods, whereby a tolerance-compensating spring assembly can be provided. According to one Another embodiment of the invention is each casting half-shell with one or equipped with several ejectors. The core casting machine can with several casting units arranged side by side can be equipped. Let it through For example, 4 or 6 cores are produced in one work cycle.

Diese und weitere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen außer aus den Ansprüchen auch aus der Beschreibung und den Zeichnungen hervor. dung und auf anderen Gebieten verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführungen darstellen können, für die hier Schutz beansprucht wird.These and other features of preferred developments of the invention go from the claims and from the description and drawings out. tion and in other areas and be advantageous and for yourself can represent protective designs for which protection is claimed here becomes.
