Claims (2)

1. Hebevorrichtung einer unteren Halterung von Formmaschinen, die aus einem oberen Gestell (1) und einem unteren Gestell (2) besteht, wobei das obere Gestell (1) unten mit einer nach unten beweglichen, oberen Halterung (11) versehen ist, während das untere Gestell (2) oben eine die untere Halterung (21) antreibende Hebevorrichtung (3) besitzt, dadurch gekennzeichnet, dass die Hebevorrichtung (3) an vier Ecken des unteren Teils der unteren Halterung (21) mit je einer Rolle (31) versehen ist, die sich gegen ein keilförmiges Stück (32) lehnt, unten dem ein gezahnter Streifen (33) untergebracht ist, wobei ein sich um eine Drehache drehendes Zahnrad (34) in die zwei gezahnten Streifen (33) eingreift, und dass die in der Mitte befindlichen beiden gezahnten Streifen (33) am einer Querleiste (35) befestigt sind, die mit einem Kolben (361) eines Druckluftzylinders (36) verbunden ist, sodass die untere Halterung (21) auf- und absteigt, wenn die beiden in der Mitte befindlichen gezahnten Streifen (33) vom Druckluftzylinder (36) in Betrieb gesetzt werden, während die außen befindlichen beiden gezahnten Streifen (33) durch das Zahnrad (34) synchron bewegt werden und somit die vier keilförmigen Stücke (32) auch in gleicher Art beweglich sind.1. Lifting device of a lower bracket of molding machines, which consists of an upper frame ( 1 ) and a lower frame ( 2 ), wherein the upper frame ( 1 ) is provided at the bottom with a lower movable upper bracket ( 11 ), while the lower frame ( 2 ) has at the top a lifting device ( 3 ) driving the lower holder ( 21 ), characterized in that the lifting device ( 3 ) is provided with a roller ( 31 ) at four corners of the lower part of the lower holder ( 21 ) which leans against a wedge-shaped piece ( 32 ), below which a toothed strip ( 33 ) is accommodated, with a gear wheel ( 34 ) rotating about a rotary axis meshing with the two toothed strips ( 33 ), and that in the middle located two toothed strips ( 33 ) are attached to a cross bar ( 35 ) which is connected to a piston ( 361 ) of an air cylinder ( 36 ), so that the lower bracket ( 21 ) rises and falls when the two in the center toothed strips ( 33 ) are put into operation by the compressed air cylinder ( 36 ), while the two toothed strips ( 33 ) on the outside are moved synchronously by the gear wheel ( 34 ) and thus the four wedge-shaped pieces ( 32 ) are also moved in the same way are mobile. 2. Hebevorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Schräge (321) des keilförmigen Stücks (32) als mehrstufige Schräge (321a) ausgebildet ist.2. Lifting device according to claim 1, characterized in that the slope ( 321 ) of the wedge-shaped piece ( 32 ) is designed as a multi-stage slope ( 321 a).
