<p>A moulding arrangement serves for at each stroke of an injection-moulding machine in which an injection mould (8,9) is mounted moulding articles (1), which is composed of components (2,3) made of different materials in cavities (10,11) formed in the injection mould (8,9) which in closed position comprises a number of cavities (10,11) corresponding each to the shape of one or more components (2,3) whereby identical cavities (10,11) are separated by angular distances and placed at equal distances from a central axis of the mould (8,9) and parts of the cavities (10,11) are formed in a separately movable section (14) of the movable mould half (8). The moulding arrangement comprises moreover an operation part (32) for displacing the section (14) to-and-fro between closed and open positions of the mould (8,9) and in open positions to turn the section (14) about said central axis angles corresponding to the angles between the cavities (10,11) to form whole cavities (10,11) in the mould (8,9) being in closed position. The moulding arrangement is capable of in each operation cycle producing articles composed of components made of each their material.</p> |
