Description

Vorrichtungen zum Absetzen des Qberkastens bei Formmaschinen sind bereits bekannt. So wurde vorgeschlagen, an den Hauptständern der Maschine zwei Tragarme undrehbar, aber in der Höhe verstellbar, anzubringen, auf deren, einem eine den Oberkasten aufnehmende Querschiene schwenkbar gelagert ist, während der andere das freie Ende dieser Schiene stützt und einen die Schwenk-ο bewegung begrenzenden Anschlag trägt.Devices for lowering the Qberbox in molding machines are already known. So it was proposed to the Main stand of the machine, two support arms can be attached that cannot be rotated, but are height-adjustable, on one of which a transverse rail receiving the upper box is pivotably mounted is, while the other supports the free end of this rail and one the swivel ο movement limiting stop carries.

Diese Bauweise ist insofern mangelhaft, als infolge der Schwenkbewegung der eine der beiden Unterstützungspunkte früher unter den' Oberkasten gelangt bzw. ihn verläßt als der andere. Hierdurch können Unfälle hervorgerufen werden, wenn nicht die zu schwenkende Querschiene sehr genau auf die Abmessungen des aufzunehmenden Oberkastens eingestellt wird.This design is deficient in that as a result of the pivoting movement of one of the both support points comes under the 'upper box or leaves it earlier than the other. This can cause accidents, if not the one to be swiveled Cross rail adjusted very precisely to the dimensions of the upper box to be accommodated will.

Dieser Mangel wird gemäß der Erfindung dadurch beseitigt, daß die Querschiene aus der Ruhe- in die Arbeitsstellung und zurück nicht um ihren einen Endpunkt gedreht, sondern parallel verschoben wird.This deficiency is eliminated according to the invention in that the cross rail from the Rest - to the working position and back not rotated around its one end point, but is moved in parallel.

Auf den Zeichnungen ist eine Ausführungsform des Erfindungsgegenstandes beispielsweise dargestellt.In the drawings, an embodiment of the subject matter of the invention is for example shown.

Claims

on plates 3, which are in the grooves of the stand 1 and are held by fastening screws 4. The protruding edge 7 of the ram 2 is stiffened by ribs 8. On the front side of the main frame 1 working ledges are provided (Fig. 1) where o with slots i8 ^a fitted plates 18 by screws. Like. Secured. ^{On these plates,} the heads 9 of arms 11 are fastened adjustable in height by means of square screw 10 and pin g a. A cross member 15 is displaceable on the upper edge of these arms 11. By means of a connecting piece 16, 16 each, which can slide on the inner surfaces of the arms 11, it is firmly connected to the arms 28, which are also displaceable.

With the connecting piece 16 , as with the arm 28, a small plate 20 ■ 20 is firmly connected, which can slide on the upper edge of the arm 11 (Fig. 2).

On the two arms 28 are tabs 23 and on one arm, on the right in Fig. 3, a bolt 24 with handle 25 and detent 24 ° is also articulated, rotatable about the same bolt. At the front end of the right arm 11 is a stop 12 adjustable by means of a T-screw 13, the bolt 14 of which can be placed in the catch 24 ″ of the bolt 24. The free ends of the tabs 23 are articulated to crank arms 22, those on both sides outside the arms 11 are keyed onto the shaft 27. This shaft, which runs parallel to the cross member 15, is rotatably supported by its two cranks 22 in the same direction in two plates 21 riveted to the outer sides of the arms (Figs. 4 and 5) ; machine side provided lock 24 is suspended in a bracket 26 which is riveted to the cross member 15, itself, that is, with this ^on; shifts arms. 11

Support arms 19 are located on the cross member 15

displaceable or otherwise in the longitudinal direction of the cross member 15 fastened adjustable.

These support arms have notches which, in turn, are adjustable.

The new device for setting down the upper box is used as follows: The head 9 of the arm 11 is adjusted accordingly on both sides of the height of the lower edge of the raised upper box. Likewise, the parallel shift of the; Crossbar 15 limiting stop 12 corresponding to the width of the molding box on the! Arms fixed by means of the toggle screw 13. The support arms 19 are screwed to the transverse beam 15 according to the length of the upper box to be lifted off. If the lifting device has now guided the upper box to its uppermost limit position, the bolt 24 is moved from its rest position, which roughly corresponds to the position in Fig. 1, into its front limit position, in which the catch 24 ^s extends over the bolt 14 lays. If all parts are correctly adjusted, the cross member 15 with its support arms 19 is advanced so far with the intermediary of the arm 28, the connecting pieces 20 and 16 that the fingers of the support arms 19 just grip in the required manner under the lower edge of the upper box frame to be opened. During this displacement movement, the arm 28 exerts a rotary movement on the right arm 22 by means of the bracket 23, which is transmitted through the shaft 27 to the left crank arm 22. Since the free end of this arm, as well as the corresponding one on the right side, is connected to the arm 28 by a tab 23, this arm and with it the left end of the cross member 15 must perform the same displacement movement. The parallel displacement of the cross member 15 is ensured in this way.
