Zuckerrohrhauer's, molded plastic handle and an apparatus for making the same.
Die bekannten, mit einem Kunststoffgriff versehenen Messer werden gegenüber solchen Messern, deren Messerangel aufgenietete Griffschalen haben, wegen der Beständigkeit der Umhüllung gegen Veränderungen während der unterschiedlichen Temperaturen beim Transport, bei der Lagerung und beim Gebrauch bevorzugt. The known knives provided with a plastic handle are used compared to knives whose tang have riveted handle scales because of the resistance of the envelope to changes during the different Temperatures during transport, storage and use are preferred.
Das Umgießen oder Umspritzen der Messerangel geschieht in der Weise, daß der Messerschaft durch einen dem Messerklingenquerschnitt entsprechenden Spalt einer zweiteiligen Form bis zum Heftrand eingesteckt und dann umspritzt wird. Großflächige Messerangeln, beispielsweise solche von Zuckerrohrhauern, können hierbei in beträchtliche Schwingungen geraten, die das Umspritzen solcher Messerangeln bisher erschwerten. The pouring or injection molding of the knife tang is done in the way, that the knife shaft through a gap corresponding to the cross section of the knife blade a two-part mold is inserted up to the binding edge and then overmolded. Large area Knife fishing, for example those of sugar cane tusks, can be considerable here Get vibrations that have made it difficult to encapsulate such knife rods.
Gegenstand der Erfindung ist eine Vorrichtung zur Herstellung eines um die Angel eines Messers, z. B. The invention is an apparatus for producing a around the tang of a knife, e.g. B.
Zuckerrohrhauers, gespritzten Kunststoffgriffes in Gestalt eines längs zweiteiligen Formkastens, bei der auch das Umspritzen großflächiger Angeln dadurch ermöglicht wird, daß die eine Kastenhälfte einen Fixierstift in der Angellängsachse dicht am Griffende hat und daß am Griffanfang in Höhe der Wurzel der Messerklinge in jeder Kastenhälfte eine quer bewegliche federbelastete, zum Halten der Angel und Abdichten des Formkastens dienende Backe liegt.Zuckerrohrhauer's, molded plastic handle in the shape of a lengthways two-part molding box, which also allows overmolding of large-area hinges it is made possible that one box half has a fixing pin in the longitudinal axis of the fishing rod close to the end of the handle and that at the beginning of the handle at the level of the root of the knife blade in each half of the box a transversely movable spring-loaded one to hold the fishing rod and sealing the molding box serving jaw lies.
Des weiteren ist Gegenstand der Erfindung ein durch diese Spritzvorrichtung hergestellter Messergriff, bei dem die Angel in der Längsrichtung am Ende eine über die Kunststoffhülle vorstehende Nase hat, die ein Loch für den Fixierstift der einen Formkastenhälfte aufweist. The invention also relates to a spray device produced by this Manufactured knife handle, in which the tang in the longitudinal direction at the end of one over the plastic sleeve has a protruding nose that has a hole for the locating pin of the one Has molding box half.
Ein Ausführungsbeispiel der Erfindung ist in Abb. I in einem durch die Ebene der sich berührenden Formhälften gelegten Längsschnitt, in Abb. 2 im Schnitt A-B, in Abb. 3 im Schnitt C-D und in Abb. 4 in der Draufsicht auf die Form bei geschnittener Messerklinge dargestellt. An embodiment of the invention is shown in Fig. I in one the plane of the touching mold halves laid longitudinal section, in Fig. 2 in section A-B, in Fig. 3 in section C-D and in Fig. 4 in a plan view of the shape when cut Knife blade shown.
Das nach der Erfindung hergestellte hauer- oder sichelförmige Messer besteht aus der Messerklinge a, der Messerangel b und dem die Messerangel b allseitig umhüllenden Griff c aus form- und gieß- oder spritzbarem und danach erhärtbarem Werkstoff, vornehmlich aber aus plastischer Spritzmasse. The tusk-shaped or sickle-shaped knife made according to the invention consists of the knife blade a, the knife tang b and the knife tang b on all sides enveloping handle c made of moldable and pourable or injectable and then hardenable Material, but mainly made of plastic injection molding compound.
Die Messerangel b wird am Ende mit einer über die Kunststoffhülle vorstehenden Nase d versehen, die als Halterung der Messerangel b in der Herstellungsform des Griffes c dient und die mit einem Loch e versehen ist, das sowohl zur Aufnahme eines Fixierstiftes zwecks Festhaltens der Messerangel b in der Form dient als auch zum Aufhängen des im Gebrauch stehenden Messers dienen kann. The knife tang b ends up with an over the plastic sleeve protruding nose d provided as a holder of the knife tang b in the manufacturing form the handle c is used and provided with a hole e is that both for inclusion a fixing pin for the purpose of holding the knife tang b in the form serves as well can be used to hang up the knife in use.
Die für die Herstellung des Griffes c der Messerangel b dienende Spritzform besteht aus den Formhälften und h, wobei die Formhälfte g feststehend und die Formhälfte h dagegen verschiebbar bzw. absetzbar angeordnet ist. Die Formhälften g und h sind in üblicher Weise gegenseitig geführt. Die muldenförmige Ausnehmung i der Formhälfte g und die entsprechende Ausnehmung k der Formhälfte h ergänzen sich zu der Form des die Messerangel b umhüllenden Messergriffs c. Die oberhalb der Form des Griffes c befindliche beiderseitige Ausnehmung j entspricht der Form der Messerklinge a. Hierbei ist am Ende jeder Ausnehmung j eine Backe l aus Metall angeordnet, die gleichzeitig als Verschluß der Form und als obere Halterung des Messers dient. Die beiden Backen l ergänzen sich zu einer geschlossenen Büchse. Sie sind in den Formhälften g und h federbelastet und in ihrer Absetzrichtung geführt befestigt. Am anderen Ende hat die Griffausnehmung i, k eine Verlängerung für die Nased, deren Loch e von einem Fixierstift rn durchsetzbar ist, der in der Absetzrichtung der beweglichen Form angeordnet und in der festen Formhälfte g befestigt ist. Auf diesen Fixierstift m wird das Messer mit dem Loch e aufgesteckt und mit ihm so in der Form zwischen den Formhälften g und lt festgehalten, daß es weder nach den Seiten noch nach oben oder unten ausweichen kann. Nach dem Aufstecken der Messerangel auf den Fixierstift in wird die Form durch Andrücken der beweglichen Formhälfte lt geschlossen. Sodann wird die Spritzgußmasse in üblicher Weise nach vorherigem Erwärmen unter hohem Druck in die Hohlform i, K gespritzt. Die Nase d der Griffangel b, die zum Aufhängen des Messers beim Aufbewahren dient, kann aber auch abgesägt und der äußeren Form des Griffes c angeglichen werden, wenn z. B. die Nase d statt am Ende der Messerangel b an deren Längsseiten angebracht sein sollte, wie dies auch möglich wäre. The one used for making the handle c of the knife tang b Injection mold consists of the mold halves and h, the mold half g being stationary and the mold half h, on the other hand, is arranged to be displaceable or removable. The mold halves g and h are mutually guided in the usual way. The trough-shaped recess i of the mold half g and the corresponding recess k of the mold half h to the shape of the knife handle enveloping the knife tang b c. The one above Recess j located on both sides of the shape of the handle c corresponds to the shape the knife blade a. Here, a jaw l made of metal is at the end of each recess j arranged, which at the same time as a closure of the form and as the upper holder of the Knife is used. The two jaws l complement each other to form a closed can. They are spring-loaded in the mold halves g and h and are guided in their deposition direction attached. At the other end, the handle recess i, k has an extension for the Nased, the hole e of which can be penetrated by a fixing pin rn, which runs in the direction of deposition the movable mold is arranged and fixed in the fixed mold half g. on this fixing pin m is attached to the knife with the hole e and with it so in the shape between the mold halves g and lt recorded that it is neither to the sides can still move up or down. After attaching the knife tang the fixing pin in the mold is closed by pressing the movable mold half. The injection molding compound is then added in the usual way after previous heating injected into the mold i, K under high pressure. the Nose d the tang b, which is used to hang up the knife when it is stored, but can also be sawn off and the outer shape of the handle c are matched when z. B. the nose d instead at the end of the knife tang b should be attached to its long sides, like this would also be possible.
