<p>A die for manufacturing eccentrics for connection of furniture parts, of the type having a substantially cylindrical shape and adapted to be inserted into a seat in a first furniture part, the eccentric (11) having a groove (15) in its side surface (14) for receiving the head of a tie rod connected to a second furniture part to be connected to the first one, the groove (15) having undercuts (19a, 21a) that in use engage the tie rod head to form a radial constraint between tie rod and eccentric so that an axial rotation of the eccentric within the seat into which it is inserted generates a pulling action on the tie rod. The die comprises two shell halves (25, 26) adapted to open in an opening direction perpendicular to an axis of the eccentric to form at least one moulding impression of an eccentric, each of the two shell halves creating, for each eccentric, such a cavity in the side surface (14) thereof as to form part of said groove (15), the die for each moulding impression comprising only one side carriage (27) movable transversely of the die opening direction in an axial direction relative to the eccentric (11), suitable for forming said undercuts (19a, 21a) in the groove (15) and an axial hole (20) in the eccentric that in use is adapted to receive a tool for rotating the eccentric.</p> |
