Abstract

A typical item produced is a damper bush (1) with outer (2) and inner (3) bushes of plastic and an intermediate layer (4) of rubber. By means of a special form tool, the plastic parts are moulded and then tue rubber contour is applied to the hot plastic. USE - To injection mould small items of plastic and rubber.

Description

Das erfindungsgemäße Verfahren als Weiterentwicklung des Verfahrens gemäß DE-A-40 25 100, das die Herstellung von Gummi-Metall-Lagern beschreibt, soll angewendet werden, um beispielsweise Kunststoff-Gummi-Lager im Verbund­ spritzgießen als gemeinsamer Fertigungsprozeß bereitzustellen. Das erfindungswesentliche dabei ist, daß in einem speziellen Werkzeug zunächst die Kunststoffteile gespritzt werden. Danach gestattet es die Formtechnik, die Kavität für den Elastomerkörper freizugeben und die Gummikontur auf den heißen Kunststoff aufzuspritzen.The inventive method as a further development of the Process according to DE-A-40 25 100, which involves the production of Rubber-metal bearings describes should be applied for example, plastic-rubber bearings in the composite to provide injection molding as a common manufacturing process. The essence of the invention is that in a special First the plastic parts are injection molded. After that, the molding technique allows the cavity for to release the elastomer body and the rubber contour to spray the hot plastic.

Mit Hilfe dieser Formtechnik ist ein äußerst rationelles Fertigungsverfahren auf Spritzgießmaschinen möglich, welche über zwei getrennte Spritzeinheiten für Gummi und Kunststoff verfügen.Using this molding technique is an extremely rational one Manufacturing processes possible on injection molding machines, which has two separate rubber injection units and plastic.

Dieses Verfahren ist auch anwendbar für die Herstellung anderer Kunststoff-Gummi-Artikel bzw. für die Herstellung von Kunststoff-Metall-Gummi-Artikeln.This method can also be used for manufacturing other plastic-rubber articles or for the manufacture of plastic-metal-rubber articles.
