For centring a plurality of plate-shaped, strip-shaped or tubular parts (3, 4, 5, 6) of a mould, guide bushes (8) are inserted in a positively locking manner in bores (7) of said parts. The guide bush (8) has at one of its ends a threaded bore (15) which serves for attaching a tool (16) for drawing the guide bush (8) out of the mutually centred parts of a mould. The tool (16) consists of a bolt (17) which bears at one of its ends a thread (18) for insertion into the threaded bore (15) and at its other end a head (19). On the bolt (17), a striker body (20) is guided, the striker body (20) being struck against the delimitation (21) of the head (19) by a striking movement in the arrow directions (25) so as, by this means, to draw the bush (8) out of the bore (7) of the mould parts (3, 4 and 5). <IMAGE>
