Description
Vorrichtung zur Herstellung von Kunststoff-Plaketten Zusatz zur Anmeldung: W 34930111/44 a -Auslegeschrift 1 179749 Die Hauptpatentanmeldung betrifft aus durchsichtigem Kunststoff bestehende, auf der Rückseite von Verzierungen versehene Plaketten, deren Befestigungsmittel durch Ausschäumen des Plakettenhohlraums mittels Kaltschaummasse verankert sind.Device for the production of plastic badges Addition for registration: W 34930111/44 a-Auslegeschrift 1 179749 The main patent application concerns from transparent Plastic plaques with decorations on the back, their Fastening means by foaming the badge cavity with cold foam compound are anchored.
Die Herstellung von Plaketten nach dieser Lehre ist nur dann möglich, wenn sichergestellt ist, daß sich die Plakettenscheibe während des Aufschäumens und Erstarrens der Kaltschaummasse in genau horizontaler Lage befindet. Diese Forderung stößt insofern auf Schwierigkeiten, als das Einspannen der Scheibe wegen der empfindlichen Außenhaut nur unter Anwendung besonderer Schutzvorrichtungen durchführbar ist und die bekannten Niederhalter nicht anbringbar sind, da ihre Ansatzstelle auf der Innenseite der Plakettenscheibe nicht von der Schaummasse bedeckt und somit sichtbar bleiben würde. The production of badges according to this teaching is only possible if it is ensured that the sticker disc during the foaming and solidification of the cold foam mass is in an exactly horizontal position. This requirement encounters difficulties insofar as the clamping of the disc because of the sensitive Outer skin can only be carried out with the use of special protective devices and the known hold-down devices cannot be attached because their attachment point is on the inside the sticker disc is not covered by the foam mass and thus remain visible would.
Die Erfindung bezieht sich auf eine Vorrichtung zur Herstellung von Plaketten der erwähnten Art, bei deren Verwendung die beschriebenen Schwierigkeiten vermieden werden. The invention relates to an apparatus for producing Badges of the type mentioned, the difficulties described when using them be avoided.
Die Vorrichtung nach der Erfindung besteht aus einer zweiteiligen, luftdicht verschließbaren Form, deren Unterteil, der die Plakettenscheibe aufnimmt, derart mit einer Vakuumanlage in Verbindung steht, daß die Plakettenscheibe beim Einlegen und während des Erstarrungsvorganges der eingefüllten Schaummasse zentriert und in ihrer Lage gehalten wird. The device according to the invention consists of a two-part, airtight sealable form, the lower part of which accommodates the disc, is in communication with a vacuum system in such a way that the sticker disc when Insertion and centered during the solidification process of the filled foam mass and held in place.
Als besonders vorteilhaft hat es sich erwiesen, das Unterteil der Form, das für die Aufnahme der Plakettenscheibe bestimmt ist, aus elastischem Werkstoff, vorzugsweise aus Gummi oder gummiähnlichem Kunststoff herzustellen, da sich dann die Plakettenscheibe unter dem Einfluß des Vakuums leicht in diese weiche Unterlage eindrückt und somit für eine gute Abdichtung sorgt. It has proven to be particularly advantageous, the lower part of the Shape, which is intended to hold the sticker disc, made of elastic material, preferably made of rubber or rubber-like plastic, because then the sticker disc easily into this soft surface under the influence of the vacuum and thus ensures a good seal.
Um sicher zu stellen, daß die in den Plakettenhohlraum eingeführten Befestigungsmittel die gewünschte Lage während des Aufschäum- und Erstarrungsvorganges der Kaltschaummasse beibehalten, ordnet man nach einem weiteren Merkmal der Erfindung im Oberteil der Form eine Halterung an, die Öffnungen zur selbstklemmenden Aufnahme des Teiles der Befestigungsmittel aufweist, der den Plakettenrand überragt. To make sure that the inserted into the badge cavity Fastening means the desired position during the foaming and solidification process retained the cold foam mass, is classified according to a further feature of the invention in the upper part of the form a bracket, the openings for the self-locking receptacle of the part of the fastening means which protrudes beyond the edge of the badge.
Auf diese Weise wird ermöglicht, daß der Teil der Befestigungsmittel, der sich innerhalb des Plakettenhohiraumes befindet, unabhängig von seiner jeweiligen Form völlig umschäumt wird. Die selbstklemmende Halterung fertigt man vorzugsweise aus zähelastischem Kunststoff an. Um das Ausstoßen der fertigen Plakette aus der Form zu erleichtern, kann man in die Vakuumleitung ein Steuerorgan einbauen, mit dessen Hilfe man die Saugluft auf Preßluft umschalten kann. Somit kann der angeschlossene Kompressor ständig in Betrieb bleiben. In this way it is made possible that the part of the fastening means, which is located within the plaque cavity, regardless of its respective Form is completely foamed. The self-locking bracket is preferably made the end tough elastic plastic. About the ejection of the finished badge from the mold To facilitate, you can install a control element in the vacuum line, with its Help you can switch the suction air to compressed air. Thus, the connected Keep the compressor running continuously.
Die Zeichnung veranschaulicht schematisch den Erfindungsgedanken an Hand eines Querschnittes durch die Vorrichtung. The drawing illustrates schematically the idea of the invention on the basis of a cross section through the device.
Die Plakettenscheibe 1 wird in den Unterteil 5 der Form eingelegt und durch Betätigen der Ventilsteuerung 14 die Verbindung zwischen Vakuumanlage und der festzusaugenden Plakettenscheibel über Kanal 12, Ventilsteuerung 14, Ventilstück 11, Hohlraum 18 und Bohrungl9 hergestellt, wodurch die Plakettenscheibe 1 zentriert und festgesetzt wird. The sticker disc 1 is placed in the lower part 5 of the mold and by actuating the valve control 14, the connection between the vacuum system and the sticker disc to be attached via channel 12, valve control 14, valve piece 11, cavity 18 and borehole 19 produced, whereby the sticker disc 1 is centered and is fixed.
Das den Hohlraum 18 bildende Zwischenstück 8 und die Grundplattel7 haben eine Dichtung 16 als Zwischenlage. Nach Einfüllen der Kaltschaummasse 2 in den Hohlraum der Plakettenscheibe 1 wird das Oberteil6 mit Deckplatte9 und die Befestigungsmittel - nämlich Traverse 3 und Schraubstifte 4 - aufnehmende Halterung 7 auf die am Zwischenstück 8 angebrachten, der Arretierung dienenden Stifte 10 aufgesetzt und durch die Schließvorrichtung 15 fest auf das Unterteil 5 der Form gepreßt. Nach Erstarren der Kaltschaummasse 2 wird das Oberteil 6 abgenommen und durch Verdrehen der Ventilsteuerungl4 der Kanal 13 freigegeben, so daß die fertige Plakette mittels Preßluft aus dem UnterteilS der Formvorrichtung herausgedrückt wird.The intermediate piece 8 forming the cavity 18 and the base plate 7 have a seal 16 as an intermediate layer. After filling the cold foam mass 2 in the cavity of the sticker disc 1 is the upper part6 with the cover plate9 and the fastening means - namely traverse 3 and screw pins 4 - receiving bracket 7 on the intermediate piece 8 attached, the locking pins 10 placed and through the locking device 15 pressed firmly onto the lower part 5 of the mold. After the cold foam mass has solidified 2, the upper part 6 is removed and, by turning the valve control 14, the duct 13 released so that the finished badge by means of compressed air from the lower partS the molding device is pushed out.
