The invention relates to an injection moulding device with an injection moulding cylinder. A coaxial worm is arranged in said cylinder and can be rotated and axially displaced by means of drive mechanisms. A spindle nut (9) is accommodated in a housing (11). Said nut can be rotated by means of a fist drive mechanism (15) and engages with a screw sleeve (8) that can be axially displaced when the spindle nut (9) is rotated. An anti-rotation safety device (12) that is connected to the housing (11) is provided. In addition, a shaft (1) is mounted on the inside of the screw sleeve (8). The shaft (1) is connected to the worm (14) on one end thereof and is provided with an axial coupling (3) at the other end thereof. One coupling component of said coupling is connected to a second drive mechanism (7). |
