Abstract

An injection unit and a blow mould are provided with two transporters for the mould cores attached to the blow mould, in the form of carriages independently movable and having a base plate on which the mould cores are fixed, so that they can carry the cores to and away from the injection unit. The injection and blowing cycles are separated and dead time is eliminated.

Description

Vorrichtung an Spritzgußmaschinen Die vorliegende Erfindung hat zum Ziel, marktgängiges Spritzgußmaschinen auch zum Einsatz von Spritzblasteilen verwenden zu können. Device on injection molding machines The present invention has for The aim is to use standard injection molding machines also for the use of injection-molded parts to be able to.

Das Spritzblas-Verfahren stellt ein relativ neues Verfahren dar, für das schon in der Patent-Literatur und auf dem Markt verschiedene Vorschläge technischer Art vorliegen. Es sind jedoch im allgemeinen neue Maschinen entwickelt worden als Einzelmaschinen zum Einsatz im Spritzblasen.The injection blow molding process is a relatively new process for that already in the patent literature and on the market various proposals technical Art exist. However, new machines have generally been developed as Single machines for use in injection blow molding.

Beim Spritzblasen laufen zwei Vorgänge ab. Der eine Vorgang ist ein Spritzgußvorgang zur Herstellung eines Vorformlings, der dann in einem Blasbereich aufgeblasen wird.There are two processes involved in injection blow molding. One process is one Injection molding process for the production of a preform, which is then placed in a blown area is inflated.

Der Gedanke liegt nun nahe, den tiefen Teil des Spritzblasens, nämlich die Herstellung des Vorformlings, in einer herkömmlichen Spritzgußmaschine vorzunehmen. Dies bedingt jedoch einen Zusatz in der Spritzgußmaschine in der Weise, daß die Form in der Lage ist sich nach beiden Achsrichtungen, sowohl nach der Spritzseite als auch, wie herkömmlich, nach der Schließseite sich bewegen kann. Außerdem ist notwendig, daß bei dieser Grundbedingung ein Fixpunkt gegeben wird, da das Einspritzen in die Trennebene des Spritzgußteiles bzw. des Vorformlings geschieht.The idea is now obvious, the deep part of injection blow molding, namely the production of the preform to be carried out in a conventional injection molding machine. However, this requires an addition in the injection molding machine in such a way that the Form is able to move in both axial directions, both on the injection side as well as, as conventional, can move towards the closing side. Also is It is necessary that a fixed point is given with this basic condition, since the injection happens in the parting line of the injection molded part or the preform.

Vorliegende Erfindung bringt diesen Vorgang zustande dadurch, daß auf der spritzseitigen starren Holmenplatte ein Kniehebel montiert wird und über diesen Kniehebel eine weitere Platte eingebaut wird und durch diesen Kniehebel in die entgegengesetzte Richtung zur Schließseite in öffnung und Schließbewegung gebracht werden kann.The present invention accomplishes this process in that A toggle lever is mounted on the rigid spar plate on the injection side and over this toggle lever another plate is installed and through this toggle lever in brought the opposite direction to the closing side in opening and closing movement can be.

Blatt 2 der Patentbeschreibung Vorrichtung an Spritzgußmaschinen Vorliegende Erfindung wird durch beiliegende Zeichnung veranschaulicht.Sheet 2 of the patent description of the device on injection molding machines The invention is illustrated by the accompanying drawing.

Abb. I zeigt das Grundprinzip einer Spritzgussmaschine, das im wesentlichen aus der starren spritzseitigen Holmenplatte (2) besteht und der verschiebbaren, durch Druck zu beaufschlagenden Holmenplatte (4). Die zusätzliche Vorrichtung wird veranschaulicht durch die Holmenplatte (1) und zwischen Holmenplatte (1) und der starren Holmenplatte (2) befindet sich der Kniehebel (3) gemäß der Darstellung in gestrecktem Zustand.Fig. I shows the basic principle of an injection molding machine, which is essentially consists of the rigid spar plate (2) on the injection side and the movable, by pressure to be applied spar plate (4). The additional device will illustrated by the spar plate (1) and between the spar plate (1) and the rigid spar plate (2) is the toggle lever (3) as shown in stretched state.

Abb.II stellt eine Variante der Vorrichtung dar, daß nämlich zwischen der starren Grundplatte (2) und der zusätzlichen Holmenplatte (1) und dem Kniehebel (3) eine weitere Grund-platte (5) vorgesehen wird, so daß die gesamte Einheit demontiert werden kann aus der normalen Spritzgußmaschine heraus und diese auch als normale Spritzgußmaschine jederzeit Verwendung finden kann.Fig.II represents a variant of the device, namely that between the rigid base plate (2) and the additional spar plate (1) and the toggle lever (3) Another base plate (5) is provided so that the entire unit can be dismantled can be out of the normal injection molding machine and this also as normal Injection molding machine can be used at any time.

Abb. III demonstriert, wie die Lagerung der Zusatzplatte (1) in den Holmen vorgenommen werden kann, um gemäß Abb.II leicht demontiert und wieder montiert werden zu können. Dies wird erreicht dadurch,daß an der Zusatzplatte (1) Ftihrungsstiicke (6) und (7) angeb-#t sind Blatt 3 der Patentbeschreibung Vorrichtung an Spritzgußmaschinen in einer Schalenteilung, wobei zur Unterstützung dieser gesamten Anordnung die Zusatzplatte auf Rollen (8) gegenüber dem Maschinenbett unterstützt wird.Fig. III demonstrates how the storage of the additional plate (1) in the Spars can be made to be easily dismantled and reassembled as shown in Figure II to be able to. This is achieved by guiding pieces on the additional plate (1) (6) and (7) are indicated Sheet 3 of the device patent description on injection molding machines in a shell division, in support of this whole Arrangement supports the additional plate on rollers (8) opposite the machine bed will.
