Spritzgußmaschine für plastische Massen, insbesondere Kunstharz Zusatz zum Patent 687 432 Nach dem Hauptpatent wird bei Spritzgußmaschinen für plastische Massen in dem den Zuhaltedruck erzeugenden Preßkolben der Spritzdruckzylinder durch eine Bohrung in dem Preßkolben mit dem Pressenzylinderraum verbunden. Durch die Anordnung des Spritzzylinders innerhalb des Preßkolbens wird dabei eine besonders einfache und gedrängte Bauart von Spritzgußmaschinen ermöglicht.Injection molding machine for plastic masses, especially synthetic resin additive to patent 687 432 According to the main patent, injection molding machines for plastic Masses in the plunger of the injection pressure cylinder generating the locking pressure a bore in the plunger is connected to the press cylinder space. Through the Arrangement of the injection cylinder within the plunger is a special one allows simple and compact design of injection molding machines. Durch die den Spritzdruckzylinder mit dem Pressenzylinderraum verbindende Bohrung wird dazu erreicht, daG die Steuerung von Spritzkolben und Preßkolben durch eine einzige gemeinsame Steuervorrichtung erfolgen kann.By connecting the injection pressure cylinder with the press cylinder space Bore is achieved to allow the injection piston and plunger to be controlled a single common control device can take place. Unter Umständen kann es nun wünschenswert sein, bei gleichbleibend,em Zuhaltedruck den Spritzdruck verändern zu können. Auch für diesen Fall ist es gemäß der Erfindung möglich, die Vorteile baulicher Art einer Spritzgußmaschine nach dem Hauptpatent auszunutzen, indem für den Spritzdruckzylinder und den Pressenzylinder gesonderte Steuervorrichtungen vorgesehen werden. In -diesem Falle wird dann auf die den Spritzdruckzylinder mit dem Pressenzylinderraum verbindende Bohrung verzichtet. Under certain circumstances it may now be desirable to keep em Locking pressure to be able to change the injection pressure. It is also appropriate for this case the invention possible, the advantages of the structural type of an injection molding machine after Take advantage of the main patent by covering the injection pressure cylinder and the press cylinder separate control devices are provided. In this case it will then on the bore connecting the injection pressure cylinder with the press cylinder space is dispensed with. In der Zeichnung ist ein Ausführungsbeispiel einer Spritzgußmaschine gemäß der Erfindung gezeigt die im wesentlichen mit dem Ausführungsbeispiel gemäß dem Hauptpatent übereinstimmt. Auch hier ist der Pressenzylinder I auf den beiden Säulen 2 fest aufgebaut. Im Pressenzylinder I befindet sich der PreßLolben 3, in dem der Spritzkolben 4 angeordnet ist. Der Sipritzkolben 4 endet in den Spritzstempel 5, der die in dem Spritzmantel 6, vorzugsweise in Form von vorgepreßten Tabletten, eingefüllte Kunstharz masse 7 in die aus der oberen Preßform 8 und der unteren Preßform 9 bestehende Form preßt. Der Spritzmantel 6 und der Pressenkolben 3 sind fest mit dem Pressenbär 10 verbunden, der auf den beiden Rückzugkolben 11 angeordnet ist, durch die er nach oben gedrückt werden kann. Zur Zuführung des Druckwassers für den Pressenzylin derraum 12 dient das Rohr I5, das zum Steulerkasten 16 führt, von dem ein Abflußrohr 17 und ein Zuflußrohr 18 wegführen. In the drawing is an embodiment of an injection molding machine according to the invention shown essentially with the embodiment according to corresponds to the main patent. Here, too, the press cylinder I is on top of the two Columns 2 firmly built up. In the press cylinder I is the press piston 3, in which the injection plunger 4 is arranged. The Sipritz piston 4 ends in the injection die 5, which is in the spray jacket 6, preferably in the form of pre-compressed tablets, Filled synthetic resin mass 7 in the from the upper mold 8 and the lower mold 9 existing mold presses. The injection jacket 6 and the plunger 3 are fixed with connected to the press ram 10, which is arranged on the two retraction pistons 11, through which it can be pushed up. For supplying the pressurized water for the Pressenzylin derraum 12 is used by the pipe I5, which leads to the control box 16, of which a drain pipe 17 and a feed pipe 18 lead away. Gemäß der Erfindung ist nun für den Spritzkolhen 4 ein besonderer Steuerkasten 21 vorgesehen, der mit einem Zuflußrohr 22 und einem Abflußrohr 23 in Verbindung steht und das Druckwasser durch ein Teleskoprohr 24 zum Spritzzylinderraum I3 leitet, während der Gegendruckraum 19 des Spritzzylinders über das Teleskoprohr 20 mit der den Gegendruck erzeugenden Druckquelie in Verbindung steht. According to the invention, there is now a special one for the spray gun 4 Control box 21 is provided with an inlet pipe 22 and an outlet pipe 23 is in communication and the pressurized water through a telescopic tube 24 to the injection cylinder space I3 conducts, while the counterpressure chamber 19 of the injection cylinder via the telescopic tube 20 is connected to the pressure source generating the back pressure. An Stelle von Teleskoprohren könnten auch andere nachgiebige Verbindungsmittel, z. B. Instead of telescopic tubes, other flexible connecting means, z. B. Metallschläuche, zur Verbindung mit dem Zylinderraum 13 bzw. mit dem Gegendruck raum 19 dienen.Metal hoses, for connection with the cylinder chamber 13 or with the Counter pressure chamber 19 are used.
