Front module for a motor vehicle

Abstract

The invention relates to a front module for a motor vehicle, wherein the front module is in one piece and is composed exclusively of plastic.

What is claimed is: 
     
         1 . A method for producing a front module for a motor vehicle, wherein the front module is in one piece and is composed exclusively of plastic, the method comprising the following steps:
 a) providing an injection-moulding device having a rotatable drum, wherein the drum has at least two identical mould cores offset with respect to one another;   b) closing one of the mould cores by a first nozzle element, wherein the first nozzle element is designed for the injection of plastic, wherein a first cavity is formed by the mould core closed by the first nozzle element, wherein the mould core which is not closed off remains empty;   c) injecting a second plastic into the first cavity in order to obtain an injection-moulded part;   d) opening the mould core containing the injection-moulded part by removing the first nozzle element, wherein the injection-moulded part remains in the mould core;   e) rotating the drum;   f) closing the empty mould core by the first nozzle element and closing the mould core containing the injection-moulded part by a second nozzle element, wherein the second nozzle element is designed for the injection of plastic, and:
 the mould core containing the injection-moulded part and the injection-moulded part, 
 the empty mould core and the second nozzle element form a second cavity; 
   g) injecting the second plastic into the first cavity in order to obtain a further injection-moulded part, and injecting a first plastic into the second cavity in order to obtain the front module;   h) opening the mould core containing the front module by removing the second nozzle element, withdrawing the front module from the cavity such that an empty mould core is formed, and repeating steps d) to h).   
     
     
         2 . The method according to  claim 1 , wherein the injection-moulded part is encapsulated by injection moulding by the first plastic. 
     
     
         3 . The method according to  claim 1 , wherein the first nozzle element and the second nozzle element are movable only in the radial direction of the drum. 
     
     
         4 . The apparatus according to  claim 1 , wherein the first nozzle element and the second nozzle element are movable only in the radial direction of the drum.
