<p>Half-moulds are used to be completed with interchangeable dowels (41, 42) with intermediate fitting permitting shape variability. Dowelling on the mobile half-mould (2) is in three sectors (5, 10, 6), the central of which is fixed whereas the side ones are mobile. When the mobile half-mould (2) starts returning, a switch (1) acts a pair of jacks (3,4) starting the converging movement of the mobile sectors which, rotating on cams, are closed. This brings to buttoning by fitting automatic blocking components of the handle halfparts, which then get out from the forming hollows by means of extractors in the form of pivots and fall into a container. The shaped are carried out through the continuity of the hollows on the half-parts of the half-moulds, where the two stick terminals (11,12,18-21,28,29) are formed, and on the dowels where the central part (16,17,24,26,27,34) is formed which completes the said stick and foresees the handle. The system allows the employ of half-moulds as fixed parts of the machine, thus reducing the installation costs and the working time as well.</p> |
