The invention relates to a multi-part casting mould (1) for a rotor hub (50) of a wind turbine with two or more rotor blade connections (20, 20', 20''), said casting mould comprising an upper moulding box (2), a lower moulding box (3) and a core (4), wherein, in the assembled state, in which the upper moulding box (2) and the lower moulding box (3) lie one on the other in a partition plane (7) and surround the core (4), the casting mould (1) encloses a cavity (10) having the shape of the rotor hub (50) to be produced, wherein a central rotor axis (8) is oriented in the casting mould (1) vertically and perpendicular in relation to the partition plane (7), wherein each rotor blade connection (20, 20', 20'') has a blade flange (22, 22', 22'') and a blade connection brace (24, 24', 24'') arranged inside the rotor blade connection (20, 20', 20''), wherein terminating planes (23) of the blade flanges (22, 22', 22'') are each at a first angle in relation to the central rotor axis (8) and are traversed by the rotor axis (8) below or above the partition plane (7). The invention further relates to a production method, to a rotor hub (50) and to a wind turbine. The casting mould according to the invention is distinguished by the fact that the blade connection braces (24, 24', 24'') span bracing planes (25) arranged at a second angle, which differs from the first angle, in relation to the central rotor axis (8). |
