Description

Einrichtung an Spritzgußmaschinen zur Lostrennung des Eängusses. Maschinen zur Herstellung von Spritzguß sind bekannt, bei denen die Form senkrecht zur Gießrichtung und seitlich von dem Steigrohr bewegt wird, um den Anguß von dem im Steigrohr erstarrten Materiale abzutrennen.Equipment on injection molding machines to separate the Eangusses. machinery for the production of injection molding are known in which the mold is perpendicular to the casting direction and moved to the side of the riser to remove the sprue from the one solidified in the riser Separate materials.

Die Erfindung bezieht sich auf eine Vervollkommnung dieser Einrichtung, indem die Formen in an sich bekannter Weise radial auf einem - Drehtisch angeordnet sind und das Metall von unten nacheinander und absatzweise in die Form gespritzt wird, und zwar derart, däß bei der Drehung des Tisches gleichzeitig der Eingußzapfen vom Gußstück abgeschert wird. In der Zeichnung ist ein Ausführungsbeispiel der Einrichtung in Ab-b. i im Schnitt. und in Abb. 2 im Grundriß dargestellt.The invention relates to an improvement of this device, in that the forms are arranged radially on a rotary table in a manner known per se and the metal is injected into the mold one after the other and intermittently from below becomes, in such a way that the sprue pin simultaneously with the rotation of the table is sheared off the casting. In the drawing is an exemplary embodiment of the facility in Ab-b. i on average. and shown in Fig. 2 in plan.

!Danach ist auf einer parallel zur Gießrichtung liegenden Achse 3 eine ScheibA 2 drehbar so angeordnet, daß eine auf der. Scheibe 2 befestigte Form: i dicht auf dem als Spritzdüse ausgebildeten Ende des Gußsteigro'hres q. aufruht.! Then, on an axis 3 parallel to the casting direction, a ScheibA 2 rotatably arranged so that one on the. Disk 2 attached shape: i close to the end of the cast riser pipe designed as a spray nozzle q. rests.

Die Scheibe 2 wird durch ein Zahnradgetriebe 5 in absatzweise Drehung gesetzt, so daß jeweils nach Beendigung des Spritzgusses in der Form i diese von dem Steigrohr sicher wegbewegt wird.The disc 2 is rotated by a gear mechanism 5 in intermittent rotation set so that in each case after completion of the injection molding in the form i this of is safely moved away from the riser.

Dadurch wird der Anguß 6 von dem in dem Düsenteil des Steigrohres erstarrten Material 7 abgeschert. Letzterer kann in bekannter Weise durch einen leichten Schlag in den Metallbehälter 8 zurückgeworfen werden.As a result, the sprue 6 is separated from that in the nozzle part of the riser pipe solidified material 7 sheared off. The latter can in a known manner by a be thrown back into the metal container 8 lightly.

Die Scheibe 2 kann in Revolveranordnung auch mehrere Formen i tragen.The disk 2 can also carry several shapes i in a turret arrangement.

Die vorsätzliche in Zwangläufigkeit auftretende Bewegung des Formtisches 2 sichert die Entfernung der ausgegossenen Form von dem Steigrohr, hält dieses für ein z. B. mechanisch erfolgendes Zurückstoßen des Materialteiles 7 frei und setzt schließlich bei der gewählten Revolverausgestaltung der Scheibe 2 eine neue Form i auf das Steigrohr auf.The deliberate inevitably occurring movement of the form table 2 ensures the removal of the poured form from the riser pipe, holds this for a z. B. mechanically occurring recoil of the material part 7 free and sets Finally, with the selected turret design of the disk 2, a new shape i on the riser pipe.

PATENT-ANSpRUcH: Spritzgußmaschine mit Einrichtung zur Lostrennung des Angusses oder Eingusses des fertigen Gußstückes von dem in der Spritzdüse erstarrten Metall, bei welcher die Form in einer senkrecht zur Gießrichtung liegenden Bahn bewegt wird, dadurch. gekennzeichnet, daß die Form anf einem 'Drehtisch (2) befestigt ist, der absatzweise so bewegt wird, daß er die dicht auf dem Ende des Steigrohres sitzende Form von diesem wegbewegt und dadurch den Eingußzapfen von der Gußform abschert und gegebenenfalls gleichzeitig eine neue Form über die Spritzdüse bewegt, sofern mehrere Formen kreisförmig auf dem Drehtisch aufgestellt sind. PATENT CLAIM: Injection molding machine with device for separating the sprue or sprue of the finished casting from the metal solidified in the spray nozzle, in which the mold is moved in a path perpendicular to the casting direction. characterized in that the mold is attached to a turntable (2) which is moved intermittently in such a way that it moves the mold, which sits close to the end of the riser pipe, away from the latter and thereby shears the sprue from the mold and, if necessary, transfers a new mold at the same time the spray nozzle moves, provided that several shapes are set up in a circle on the turntable.
