A moulding method and a mould for carrying out said method, carried out by a mould for a conventional injection press, realising a piece in one or more injectable materials, the mould comprising a mobile part and a fixed part, on such mobile and fixed parts being realised respective impressions, which define, when the mobile part is closed against the fixed part, recesses suitable for receiving the injectable materials in at least two successive injection steps; the method comprises a step of housing a sliding element (20;120,220;320;420;520;620;720;820;920;1020;1120;1220;1320;1420;1520; 1620;1620b;1720;1820;1920;2020) in at least a first recess (16;116;216;316,416;516;616;716;816;916;1016;1116;1216;1316;1416;1516; 1616;1616b;1616c;1716;1816;1916;2016), a first injection step in such a first recess, after which a first part of the piece remains fixed on a surface integral to such a sliding element, a displacement step of such a first part of the piece in a second recess (18;118;218;318;418;518;618;718;818;918;1018;1118;1218;1318;1418;1518; 1618;1718;1818;1918,2018) and then a second injection step in such a second recess. <IMAGE> |
