Description

Form zur Herstellung auswechselbarer Gummi-Überzieh-Absätze Die Erfindung betrifft eine Form zur Herstellung auswechselbarer Gummi-Überzieh-Absätze, mit der es möglich ist, auswechselbare Gummi-überzieh-Absätze sauber herstellen und nach der Vulkan.isation unbeschädigt herausnehmen und abstreifen zu können.Mold for making interchangeable rubber boot heels The invention relates to a mold for the production of exchangeable rubber cover heels with which it is possible to make replaceable rubber pull-on heels cleanly and afterwards to be able to remove and wipe off the vulcanization undamaged.

Die Erfindung besteht darin, daß die den Hohlraum der Absätze bildenden Kerne in den Formhohlräumen verschiebbar und gegen ein Herausziehen aus der Form gesichert sind. Die Kerne sind zweckmäßig mit einem Führungsansatz in einer unterhalb des Formblocks angeordneten Führungsplatte geführt und werden mit ihren Sperrplatten von Aussparungen in der Unterplatte der Form aufgenommen.The invention consists in that the forming the cavity of the paragraphs Cores can be displaced in the mold cavities and cannot be pulled out of the mold are secured. The cores are useful with a guide approach in one below of the mold block arranged guide plate and are guided with their locking plates added by recesses in the bottom plate of the mold.

In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt, und zwar zeigt Abb. z einen OOuerschnitt einer teilweise geöffneten Form mit einem ganzen und einem mehrteiligen Kernstück, letzteres in hochgeschobener Stellung, und Abb. 2 einen Längsschnitt der Form in gebrauchsfertiger Stellung ohne Verschlußdeckel.In the drawing, the subject matter of the invention is in one embodiment shown, namely Fig. z shows a cross section of a partially open Form with a whole and a multi-part core, the latter in a pushed-up shape Position, and Fig. 2 a longitudinal section of the form in the ready-to-use position without Sealing cap.

Der ungeteilte Formblock a ist mit einer Anzahl Förmnester b versehen. Unterhalb des Formblocks a ist eine Führungsplatte c durch Schrauben d befestigt.The undivided mold block a is provided with a number of shaped cavities b. Below the mold block a, a guide plate c is attached by screws d.

In die Formnester b ist ein Kernstück e eingesetzt, dessen Führungsfuß f in der Führungsplatte c eingepaßt ist. Unterhalb des Führungsfußes f ist eine Sperrplatte g angeordnet, die als Auflagefläche des Kernstücks e in hochgeschobener Stellung dient und @demselben außerdem einen festen Halt gewährt.A core piece e is inserted into the mold cavity b, its guide foot f is fitted in the guide plate c. Below the guide foot f is a Arranged locking plate g, which is pushed up as a support surface of the core piece e in Position serves and @the same also grants a firm hold.

In dem zweiteiligen Kern c (s. Abb. s rechts) ist der Oberflächenteil h vom Kernstück getrennt und mit seiner Führungslasche i in demselben verschiebbar angeordnet. Im Führungsfuß f desselben ist der Führungsschlitz k an drei Seiten verbreitert, worin die an der Führungslasche i befestigte Sperrplatte l Führung hat.In the two-part core c (see Fig. S on the right), the surface part h is separated from the core piece and arranged in the same with its guide tab i so that it can be moved. In the guide foot f of the same, the guide slot k is widened on three sides, in which the locking plate attached to the guide bracket i has a guide.

Der Rahmenunter satt fit hat Ausschnitten, in die der Kernfuß f mit seiner Sperrplatte g versenkt wird, wobei diese im Ausschnitt n leichte Führung hat und mit der Auflagefläche des Rahmenuntersatzes nz. abschneidet.The frame lower fit has cutouts n into which the core foot f with its locking plate g is sunk, whereby this has easy guidance in the cutout n and with the support surface of the frame base nz. cuts off.

Zum Auflegen des Formblocks a auf den Untersatzrahmen in und .der Verschlußplatte o auf ersteren ist derselbe an den Ecken der Unter-- und Oberfläche mit Führungslöchern p versehen für an der Oberfläche des Untersatzrahmens na und an der Unterfläche der Verschlußplatte o sitzende Führungsstifte q.To place the mold block a on the base frame in and .the closure plate o on the former, it is provided with guide holes p at the corners of the base and surface for guide pins q on the surface of the base frame na and on the underside of the closure plate o.

Die Handhabung und Arbeitsweise der Form ist folgende: Die einzelnen Teile zu der Form werden zusammengeschoben (Abb.2-), und ist dieselbe alsdann gebrauchsfertig. Nachdem sämtliche Formnester b mit ausgestanzten Stücken der unvulkanisserten Gummimasse angefüllt sind, welche über die Oberfläche des Formblocks a hinausragen, wird die in Abb. r dargestellte Verschlußplatte o in Führung aufgelegt und durch hydraulischen Druck in der Vulkanisierpresse fest auf den Formblock a gepreßt, wodurch die Gummimasse bis nach unten in die Formnester getrieben wird. Nach der Vulkanisation wird zuerst die Verschlußplatte o abgenommen und der Untersatzrahmen m ebenfalls von der Form entfernt. Die jetzt freigelegten Kernfüße f werden auf den Arbeitstisch aufgestoßen, wodurch der Formblock a nach unten fällt und mit der Führungsplatte c auf die an den Kernfüßen angeordneten Sperrplatten g zu ruhen kommt. Die Kerne ragen jetzt über den Formblock a, so daß die Gummiabsätze von den Kernen b abgezogen werden können.The handling and working of the form is as follows: The individual Parts of the mold are pushed together (Fig.2-), and the same is then ready for use. After all mold cavities b with punched-out pieces of the unvulcanized rubber compound are filled, which over the surface of the mold block a protrude, the locking plate o shown in Fig. r is placed in the guide and through hydraulic pressure in the vulcanizing press firmly pressed onto the mold block a, whereby the rubber compound is driven down into the mold cavities. After vulcanization the closure plate o is removed first and the base frame m as well removed from the shape. The now exposed core feet f are on the work table pushed open, whereby the mold block a falls down and with the guide plate c comes to rest on the locking plates g arranged on the core feet. The cores now protrude over the mold block a so that the rubber heels are pulled off the cores b can be.

Für besonders zähe Gummimassen ist der Kern zweiteilig ausgebildet, um den festgespannten Gummiabsatz noch durch Hochdrücken des Kernoberflächenteils von dem unteren Kernteil zu befreien und dann, den Gummiabsatz noch leichter abziehen zu können.For particularly tough rubber compounds, the core is designed in two parts, around the clamped rubber heel by pushing up the core surface part to free from the lower core part and then pull off the rubber heel even easier to be able to.
