Claims (2)

1. Gießformverriegelungszylinder (2) für eine Spritzgießmaschine, gekennzeichnet durch
einen großen Direktschub-Gießformveniegelungszylinder (2), zwei schnellen Ölzylindern (17), die jeweils an beiden Seiten des Gießformverriegelungszylinders (2) angeordnet sind, um eine bewegliche Gießformbasis (13) schwenkend zu schieben und zurückzuziehen, wobei die bewegliche Gießformbasis (13) die Gießform (15) trägt, um sie zu schließen oder zurückzuziehen, wobei der Gießformverriegelungszylinder (2) dazu dient, die Gießform (15) vollständig zu verriegeln, wenn die Gießform (15) nahezu geschlossen ist, wobei
das Ende des Gießformverriegelungszylinders (2) einen ringförmig vorstehenden Abschnitt (211) besitzt, der in ein Gehäuse (22) des Gießform­ verriegelungszylinders (2) eingesetzt ist,
ein Kolben (23) im Gehäuse (22) in einem gewissen Abstand von der Innenwand des ringförmig vorstehenden Abschnitts (211) angeordnet ist,
eine Kolbenstange (24) zwischen dem Kolben (23) und der beweg­ lichen Gießformbasis (13) befestigt ist, wobei der Kolben (23) leicht im Abschnitt bewegt werden kann, mit Ausnahme des ringförmig vorstehenden Abschnitts (211) im Gehäuse (22), durch Betätigen der schnellen Ölzylinder (17), wobei der durch Betätigen des Steuerventils (25) unter Druck gesetzte Kolben (23) sich im ringförmig vorstehenden Abschnitt (211) bewegt, um die Gießform (15) zu schließen, und wobei ein großes Volumen an Drucköl im Gehäuse (22) verbleibt, so daß die Abmessungen eines Öltanks zum Speichern des Drucköls verringert sind und folglich die Größe, das Gewicht und die Kosten der entsprechenden Komponenten entsprechend reduziert sind.1. mold locking cylinder ( 2 ) for an injection molding machine, characterized by
to a movable Gießformbasis (13) to push a large direct thrust Gießformveniegelungszylinder (2), two quick oil cylinders (17) which are arranged on both sides of Gießformverriegelungszylinders (2) each pivotally and withdraw, the movable Gießformbasis (13) mold (15), to close them or withdraw, whereby the Gießformverriegelungszylinder (2) is used to completely lock the mold (15) when the mold (15) is almost closed, wherein
the end of the mold locking cylinder ( 2 ) has an annular projecting section ( 211 ) which is inserted into a housing ( 22 ) of the mold locking cylinder ( 2 ),
a piston ( 23 ) is arranged in the housing ( 22 ) at a certain distance from the inner wall of the annularly projecting section ( 211 ),
a piston rod ( 24 ) is fixed between the piston ( 23 ) and the movable mold base ( 13 ), the piston ( 23 ) being easily movable in the section, with the exception of the annular projecting section ( 211 ) in the housing ( 22 ), by operating the rapid oil cylinders ( 17 ), the piston ( 23 ) pressurized by the operation of the control valve ( 25 ) moves in the annular protruding portion ( 211 ) to close the mold ( 15 ), and a large volume Pressure oil remains in the housing ( 22 ), so that the dimensions of an oil tank for storing the pressure oil are reduced and consequently the size, the weight and the cost of the corresponding components are reduced accordingly. 2. Gießformverriegelungszylinder (2) nach Anspruch 1, dadurch gekennzeichnet, daß die Kolbenstange (24) aus mehreren kleinen Kolbenstangen besteht, um die Abmessungen der Stirnfläche des Kolbens (23) zu erhöhen und somit die Rückzugskraft für die Gießform (15) zu erhöhen und somit zu verhindern, daß die Gießform (15) zu langsam zurückgezogen wird.2. mold locking cylinder ( 2 ) according to claim 1, characterized in that the piston rod ( 24 ) consists of several small piston rods in order to increase the dimensions of the end face of the piston ( 23 ) and thus to increase the retraction force for the mold ( 15 ) and thus preventing the mold ( 15 ) from being pulled back too slowly.
