Claim:
A method for injection-moulding a component comprising at least a first portion and a second portion which are contiguous, are from a moulding operation and are composed of different materials, comprising the successive steps of: providing a mould comprising a moulding cavity ( 10 ), and at least one panel ( 16 , 18 , 20 , 54 , 56 ) for separating the cavity into at least two compartments ( 24 , 26 ) for moulding the first and second portions, the panel being movable between an active position, in which the panel ( 16 , 18 , 20 , 54 , 56 ) extends in the cavity ( 10 ) in order to separate the two compartments ( 24 , 26 ), and a rest position, in which the panel ( 16 , 18 , 20 , 54 , 56 ) is withdrawn from the cavity ( 10 ) in order to join together the two compartments ( 24 , 26 ), the panel ( 16 , 18 , 20 , 54 , 56 ) moving between the active position and the rest position through an opening ( 22 ) which is provided in a wall ( 12 ) of the cavity ( 10 ), said mould further comprising at least one shutter ( 32 , 34 ) which is movable between an open position, in which the shutter ( 32 , 34 ) is disengaged from the opening ( 22 ) in order to allow the panel ( 16 , 18 , 20 , 54 , 56 ) to be moved into an active position, and a closed position, in which the shutter ( 32 , 34 ) closes at least a region of the opening ( 22 ) in order to close the cavity ( 10 ) when the panel ( 16 , 18 , 20 , 54 , 56 ) is in a rest position; moving said at least one panel ( 16 , 18 , 20 , 54 , 56 ) into the active position, to separate said moulding cavity into the two compartments ( 24 , 26 ); injecting a first material into a first one of the two compartments ( 24 , 26 ); moving the at least one panel ( 16 , 18 , 20 , 54 , 56 ) into the rest position in order to join together the two compartments ( 24 , 26 ); closing the opening at least partially by means of the least one closure shutter ( 32 34 ); injecting a second material into a second one of the two compartments ( 24 , 26 ).
