Claims20
An apparatus for a motor vehicle, wherein the apparatus comprises:
- a front module in one piece and composed exclusively of plastic, wherein the front module has a trapezoidal shape, the front module further comprising:
- two horizontal support elements which are spaced apart from one another, wherein at least one of the two horizontal support elements is an upper horizontal support element;
- two vertical support elements which are spaced apart from one another, wherein at least two of the support elements are connected to one another by transverse struts, wherein the support elements are comprised of a first plastic and the transverse struts are comprised of a second plastic, wherein the first plastic is significantly less strong than the second plastic;
- at least two longitudinal support plates, wherein the longitudinal support plates are arranged on the vertical support elements and are provided for attaching the front module to a vehicle bodywork, wherein the longitudinal support plates are arranged at the level of the connection points between the respective vertical support elements and the transverse struts on the vertical support elements.
The apparatus according to claim 0, wherein the upper horizontal support element is connected by the transverse struts to the vertical support elements or to the lower horizontal support element.
The apparatus according to claim 0, wherein at least one of the support elements has at least a first section and a second section, wherein the first section is comprised of the first plastic and the second section is comprised of the second plastic.
The apparatus according to claim 0, wherein at least the vertical support elements have the first a first section and a second section the second sections, wherein the second section is formed between the connection points of the respective vertical support elements and the longitudinal support plates.
The apparatus according to claim 0, wherein the first plastic is a plastic which can be deformed when something impacts against the front module.
The apparatus according to claim 0, wherein the second plastic is encapsulated by injection moulding by the first plastic.
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).
