Claims (6)

1. Überdruck-Vakuumgießanlage zum Gießen von Gießharz aus zwei oder mehr Komponenten mit niedriger und hoher Viskosität.
  • 1. 1-1 Durch eine Druckdifferenz zwischen Gießharzkammer (G) und Werkzeugkammer (W) wird Gießharz mit niedriger und hoher Viskosität in eine Form (4) im evakuierten Raum gegossen.
  • 2. 1-2 Durch eine Sperrkugel (7) wird das Schlauchventil (5) gesteuert.
1. Overpressure vacuum casting machine for casting resin from two or more components with low and high viscosity.
  • 1. 1-1 Due to a pressure difference between the casting resin chamber (G) and the tool chamber (W), casting resin with low and high viscosity is poured into a mold ( 4 ) in the evacuated space.
  • 2. 1-2 The hose valve ( 5 ) is controlled by a locking ball ( 7 ).
2. Überdruck-Vakuumgießanlage nach Anspruch 1 dadurch gekennzeichnet, dass durch die Luftzufuhr über die Belüftungnskanäle (9) zur Gießharzkammer (G) und aufgrund der Verhinderung das Druckausgleich zwischen Gießkammer (G) und Werkzeugkammer (W) und durch das Rückschlagventil (8) ein Druckdifferenz somit die Wirkung einer das Gießharz in kurze Zeit in die Form pressenden Pumpe entsteht.2. positive pressure vacuum casting system according to claim 1, characterized in that by the air supply via the ventilation channels ( 9 ) to the casting resin chamber (G) and due to the prevention of pressure equalization between the casting chamber (G) and tool chamber (W) and by the check valve ( 8 ) Pressure difference thus creates the effect of a pump that presses the casting resin into the mold in a short time. 3. Überdruck-Vakuumgießanlage nach Anspruch 1-2 dadurch gekennzeichnet, dass sie mit einer Verbindung (3) zwischen zwei Kammern ausgerüstet ist. 3. positive pressure vacuum casting system according to claim 1-2, characterized in that it is equipped with a connection ( 3 ) between two chambers. 4. Überdruck-Vakuumgießanlage nach Anspruch 1-3 dadurch gekennzeichnet, dass die Verbindung mit einem Ventil (5) ausgerüstet ist.4. positive pressure vacuum casting system according to claim 1-3, characterized in that the connection is equipped with a valve ( 5 ). 5. Überdruck-Vakuumgießanlage nach Anspruch 4 dadurch gekennzeichnet, dass das Verbindungsventil durch einen Materialstandfüller (7) gesteuert wird.5. positive pressure vacuum casting system according to claim 4, characterized in that the connecting valve is controlled by a material level filler ( 7 ). 6. Überdruck-Vakuumgießanlage nach Anspruch 1-5 dadurch gekennzeichnet, dass die zwei voneinander getrennten Kammer (Gießharz (G)- und Werkzeugkammer (W)), das Füllstandsystem (Sperrkugel 7), die Verbindungsstuck (3) mit Sicherheitsventil (5) und die Steuerungseinheit (6),Rückschlagventil (8), Belüftungsventil (9&10) eine einheitliche Überdruck-Vakuumgießanlage sind.6. positive pressure vacuum casting system according to claim 1-5, characterized in that the two separate chambers (casting resin (G) - and tool chamber (W)), the level system (locking ball 7 ), the connector ( 3 ) with safety valve ( 5 ) and the control unit ( 6 ), check valve ( 8 ), ventilation valve (9 & 10) are a uniform overpressure vacuum casting system.
