<p>The invention relates to an injection moulding machine comprising a lift drive in the form of an electromotive spindle drive (1, 9) and a working memory which is associated thereto, is loaded by means of the spindle drive in a displacement phase of the same, and is unloaded in another displacement phase, under power amplification of the electric motor (9), especially for the pulsating actuation of the ejector (2). According to the invention, the electrical energy consumption of the spindle drive is significantly reduced by the fact that the working memory consists of two pressure spring arrangements (15, 16) which actuate the spindle drive in opposite directions and which are compensated in terms of force at a distance to the lift end positions of the spindle drive.</p> |
