Abstract

A tool for a resin transfer molding method comprises a cavity, a resin trap and a transition region, wherein the cavity is designed such that a component can be accommodated in it. Furthermore, the resin trap is integrated in the tool, and the transition region is designed such that with it a connection between the cavity and the resin trap can be established.

Claims (21)

1. A tool for a resin transfer moulding method, the tool comprising:

a mould;

a mould cover;

a cavity;

a resin trap;

a transition region;

a pressure means;

a pressure means connection coupling the resin trap to the pressure means;

wherein the cavity accommodates a component therein;

wherein the resin trap is integrated in the tool;

wherein the transition region establishes a connection between the cavity and the resin trap;

wherein the transition region comprises a separation element;

wherein the pressure means is configured at least to positively pressurize the resin trap and wherein the resin trap communicates with the cavity;

wherein the cavity, the resin trap and the transition region are integrated in the tool and are formed, when the mould and the mould cover are joined;

wherein the transition region comprises a separation element arranged between the cavity and the resin trap and configured so as to form a siphon-like transition connection between the cavity and the resin trap; and

wherein the siphon-like transition connection is located below a bottom portion of the resin trap.

2. The tool of claim 1 , wherein the separation element is arranged between the cavity and the resin trap such that the separation element at least partly engages the connection between the cavity and the resin trap such that the connection between the cavity and the resin trap is closable at least in part.

3. The tool of claim 2 , wherein the separation element is integrated in the mould cover and/or in the mould.

4. The tool of claim 1 , wherein the resin trap comprises an output connection.

5. The tool of claim 4 , wherein the output connection is couplable to a pump.

6. The tool of claim 1 , wherein the cavity comprises an input connection.
