Description
Zur billigen Herstellung durch Gießen oder Pressen der im Patent 876 977 beschriebenen; zum Einstecken von Stäbchen mit einer größeren Anzahl Bohrungen versehenen Verbindungsstücke bedarf es wegen der radialen Bohrungen einer besonderen Einrichtung.For inexpensive manufacture by casting or pressing that described in the '876 patent 977 described; for inserting sticks with a large number of holes provided connecting pieces are required because of the radial bores a special one Furnishings.
Guß- oder Preßformen, bei denen in den Formlingen Hohlräume durch einzeln ein- und ausrückbare Kernstifte ausgespart werden, sind bekannt. Bei der Erfindung lassen sich durch die Verwendung mehrerer Druckringe die Kernstifte jedoch in vorteilhafter Weise gruppenweise betätigen.Casting or compression molds, in which cavities in the moldings individually retractable and disengageable core pins are recessed are known. In the In the invention, however, the core pins can be removed by using several pressure rings operate in groups in an advantageous manner.
Der weitere Erfindungsgedanke, wonach die Kernstifte durch Winkelhebel an die Druckringe angelenkt sind, ist ebenfalls ein Fortschritt gegenüber den bisher bekannten Vorrichtungen dieser. Art. .The further inventive idea, according to which the core pins by angle lever are hinged to the pressure rings, is also an advance over the previous known devices of this. Art.
In Abb. i ist beispielsweise die Form für ein kugeliges Verbindungsstück im Schnitt und in Abb. a in der Draufsicht A-A dargestellt. Auf der linken Seite des Schnittes ist die Form geöffnet, auf der rechten Seite dagegen im Sinne der Pfeile eingespannt und geschlossen.In Fig. I, for example, the shape for a spherical connecting piece is shown in section and in Fig. A in plan view AA. On the left side of the section the shape is open, on the right side, however, it is clamped and closed in the direction of the arrows.
In beiden Abbildungen ist der Formling a mitten durchgeschnitten, wobei die Schnittflächen kreuzweise schraffiert sind. In der unteren Formhälfte b sind in bezug auf die Hauptachse B-B die Kernstifte c schräg und die Kernstifte d waagerecht angeordnet. In der oberen Formhälfte e liegen die Kernstifte f schräg. zur Hauptachse. Auf jeden beweglichen Kernstift wirkt eine Schraubenfeder g. Die Gruppe der Kernstifte c wird durch den Druckring h, die Gruppe der Kernstifte d durch den, Druckring i und die Gruppe der Kernstifte f durch Druckring k betätigt.In both figures, the molding a is cut through in the middle, the cut surfaces being cross-hatched. In the lower mold half b , the core pins c are arranged obliquely with respect to the main axis BB and the core pins d are arranged horizontally. In the upper mold half e, the core pins f are inclined. to the main axis. A helical spring g acts on each movable core pin. The group of core pins c is operated by the pressure ring h, the group of core pins d by the pressure ring i, and the group of core pins f by the pressure ring k.
Die Beweglichkeit der Druckringe beim Öffnen der Form ist derart begrenzt, daß die Kernstifte nicht herausfallen können. Zu diesem Zweck sind entsprechend der Darstellung in Abb. i Bolzen L, die einen Anschlagkopf m haben, mit Ansätzen n des Druckrings i verbunden. Durch Schraubenfedern. wird der Druckring beim Öffnen der Form rückgestellt. Ähnliche Anordnungen kommen fürdie Druckringe h und k in Betracht.The mobility of the pressure rings when opening the mold is so limited that that the core pins cannot fall out. For this purpose are accordingly the illustration in Fig. i Bolts L, which have a stop head m, with lugs n of the pressure ring i connected. By coil springs. becomes the pressure ring when opening the shape reset. Similar arrangements come for the pressure rings h and k in Consideration.
Die Druckringe h, i und k haben Abschrägungen p, q und y, durch die sich die Schließ- und Öffnungsbewegung parallel zur Hauptachse B-B auch auf die Kernstifte bewegend auswirkt. Verbindet man jedoch die Kernstifte durch Winkelhebel gelenkig mit den Druckringen, so werden die Kernstifte durch die Bewegung der Druckringe sowohl ein- als auch ausgerückt. Federn zur Rückstellung sind dann nicht erforderlich.The pressure rings h, i and k have bevels p, q and y, through which the closing and opening movement parallel to the main axis BB also has a moving effect on the core pins. However, if the core pins are articulated to the pressure rings by means of angle levers, the core pins are both engaged and disengaged by the movement of the pressure rings. Resetting springs are then not required.
Die Wirkungsweise der erfundenen Einrichtung ist derart, daß beim Schließen der Form die Druckringe die entweder federbelasteten oder an Winkelhebel angelenkten Kernstifte in den Hohlraum der Form vorschieben, während beim Wiederöffnen die Kernstifte rückgestellt werden, worauf der fertige Formling aus der Form genommen werden kann.The operation of the invented device is such that when Close the mold the pressure rings either spring-loaded or on toggle levers advance hinged core pins into the cavity of the mold while reopening the core pins are reset, whereupon the finished molding is removed from the mold can be.
In Abb. 3, die der Seite C der Abb. i entspricht, ist die Anordnung eines Winkelhebels s dargestellt. Er ist durch das Gelenk t mit dem Kernstift dl. und durch das Gelenk u mit dem Druckring il verbunden; seine Drehachse v ist in der unteren Formhälfte bi gelagert. Der Druckring il ist bei w an der die Schließ- und Öffnungsbewegung übertragenden Vorrichtung der Gieß- oder Formmaschine befestigt. Diese Art der Betätigung der Kernstifte läßt sich sinngemäß auch an den Druckringen h und k ausführen. Der Gebrauch von Winkelhebeln macht es notwendig; daß die Formhälften so lange in geschlossener Lage gehalten werden, bis alle Kernstifte ausgerückt sind.In Fig. 3, which corresponds to side C of Fig. I, the arrangement is an angle lever s shown. He is through the joint t with the core pin dl. and connected by the joint u to the pressure ring il; its axis of rotation v is in the lower mold half is stored bi. The pressure ring il is at w on which the closing and opening movement-transmitting device of the casting or molding machine attached. This type of actuation of the core pins can also be applied to the pressure rings perform h and k. The use of angle levers makes it necessary; that the mold halves be held in the closed position until all core pins are disengaged.
Die Kernstifte x können mit der Form fest verbunden sein, da sie in der Schließ- und Öffnungsrichtung liegen.The core pins x can be firmly connected to the shape, as they are in the closing and opening directions.
