Abstract

Containers and boat and vehicle bodies of plastics are produced by casting plastics around filling bodies in moulds. Pref. the moulds are multi-part and have composite parts and the like placed in their interior. The moulds are pref of, or lined with, silicone rubber.

Description

Bezeichnung: Verfahren und deren Vorrichtungen zur zur Herstellung von Kunststoffteilen.Designation: Process and their devices for the production of plastic parts.

Die Erfindung Betrifft ein Verfahren und deren Vorrichtungen, zur Herstellung von Teilen uer Verwendung von gießbarem Kunststoff.The invention relates to a method and their devices for Manufacture of parts using castable plastic.

In der Haupsache werden Kunststoffteile in Spritzformen hergestellt. Dazu sind teuere Stahlformen nötig. Nur durch große Stückzahlen ist eine Wirkschaftlichkeit gegeben, Außeredem ist die Gestaltung dieser Teile an gewisse technische Regeln gebunden, so z.B. wirken sich große Querschnittsänderungen schädlich aus.Most of the time, plastic parts are manufactured in injection molds. This requires expensive steel molds. Only through large numbers is a reality In addition, the design of these parts is based on certain technical rules bound, e.g. large changes in cross-section have a detrimental effect.

Mittels Auflegen von Kunststoff getränkten Matter auf Formen können ebenfalls Kunststoff gefertigt werden Dabei ist mit relativ hohem Arbeitzeitsaufwand zu rechnen.By placing plastic soaked matt on molds plastic can also be manufactured to be expected.

ss handelt sich überwiegend um grö?aere Teile wie Behalter Bootskörper Karoserien u. dgl.ss are mainly larger parts such as container hulls Bodies and the like

Erfindungsgemäß ird vorgeschlagen in Formen Füllkörper mit gießbarem Kunststoff zu umgießen. Die Formen können mehrteilig sein, und Verbindungselemente u.dgl. aufnehmen, die dann fest mit dem fertigen Kunststoffteil verbunde sind, Sie sind beispielsweise aus Silicon-Kautschuk, oder sind mit Silicon-Kautschuk ausgekleidet.According to the invention ird proposed in forms filler with pourable Pouring around plastic. The shapes can be in several parts, and connecting elements and the like, which are then firmly connected to the finished plastic part, you are for example made of silicone rubber, or are lined with silicone rubber.

Die Zeichnung zeigt ein Ausführungsbeispiel.The drawing shows an embodiment.

Um den Füllkörper 1 wird in den Hohlraum 2 gießbarer Kunststoff eingegossen. Die Innenwandungen 3 besteigen beispielsweise aus Silicon-Kautschuk. Die außere Schale 4 einschließlich der Innenwandungen 3 sind geteilt . das eingelegte Teil 6 beim Gießen zusammen mit dem Füllkörper 1 von Kunststoff umgeben und verbindet sich mit gesamten Teil. Ist der gießbare Kunststoff erhärtet wird er er aus der relativ billigen Form entnommen.Around the filling body 1, pourable plastic is poured into the cavity 2. The inner walls 3 are made of silicone rubber, for example. The outer one Shell 4 including the inner walls 3 are divided. the inserted part 6 surrounded by plastic during casting together with the filler body 1 and connects deal with whole part. If the castable plastic has hardened, it will be removed from the Taken from relatively cheap form.
