Abstract

The invention relates to a method and a removal device for the automatic removal of injection moulded parts from the half moulds (10, 11) of injection moulding machines. By installing additional vacuum storage element (61) in consumer proximity, the necessary vacuum is available for each removal in an additional area, independent from pressure variations in the vacuum system. Before the beginning of each removal, the available system is monitored by sensor means (70, 71, 72) and by maintaining a vacuum-limit value a movement authorisation is transmitted to the removal robot (30). A pressure switch threshold value is also determined for the vacuum which is adjusted in close proximity to the suction cup during the removal of the injection moulded parts (1) by the suction cups (44) of the removal robot (30). If the pressure switch threshold value is reached as a result of sufficient closeness of the injection moulding parts (1) to the suction caps (44), the removal robot (30) is authorised, by means of a machine control, to carry out additional movements. The pressure switch threshold value can be set as a percentage of the start vacuum at the beginning of each removal and as a result, the time and removal safety for each part or production charge are optimised.
