An injection moulding machine for producing components in two or more different plastics has a fixed platen (3), a moving platen (6) and an additional tool clamping arrangement (8, 9, 18) between them which moves relative to the platens and swivels on axles perpendicular to the tie bars (4, 5). The additional tool clamping arrangement includes two carrier blocks (8, 9), one above the other, guided along the tie bars (4, 5). Each carrier block (8, 9) has a bearing for the vertical axles of a prism-shaped tool half carrier (18) carrying additional tool halves (28, 29) on each parallel face, each acting in conjunction with the tool halves (30, 31) on the fixed and moving platens (3, 6). The tool carrier (18) can be rotated to face either tool half (30, 31). Two or more power units (14, 16) move the carrier blocks (8, 9) along the tie bars (4, 5) to vary the spacing between the tool carrying platens (3, 6) and carrier blocks (8, 9). |
