Abstract

Abstract Translated from German Es wird eine Einrichtung offenbart zum schnellen und sehr exakten Öffnen und Schließen der Formhälften einer Streck­blasmaschine zum Blasformen von Hohlkörpern aus thermoplasti­schem Kunststoff. A device is disclosed for quickly and very precisely opening and closing the mold halves of a stretch blow molding machine for blow molding hollow bodies made of thermoplastic material. Die Formhälften werden mit Abtriebsschwingen, die mit Antriebsschwingen eines Viergelenkgetriebes in Verbindung stehen, gekoppelt, wobei der Gestelldrehpunkt des Viergelenk­getriebes unmittelbar am Ende der Formteilfuge angeordnet wird. The mold halves are coupled to output rockers which are connected to drive rockers of a four-bar linkage, the frame pivot point of the four-bar linkage being arranged directly at the end of the molding joint. Die Antriebsschwinge des Viergelenkgetriebes wird durch Mantelkurven aufweisende Kurvenzylinder, in die Kurvenrollen eines Steuerschiebers eingreifen, gebildet. The drive rocker of the four-bar linkage is formed by cam cylinders which have cam curves and in which cam rollers of a control slide engage.
