Electrical injection moulding device for plastic injection moulding presses

摘要

The device has a drive spindle (14) driving a plasticizing screw in such a manner that the spindle performs translatory feed motion during injection of plastic material in a form cavity, rotating motion around own axis, translatory rotating motion around own axis and rear movement during plasticizing phase of plastic material. A spindle (19) is driven by a drive motor (31) combined with the drive spindle. The drive spindle and the spindle are coupled to each other such that the translatory and rotary movements are transferred to the plasticizing screw in both directions.
