发明名称 Sätt att lösgöra formade plastdetaljer vid formsprutning
摘要 The disclosure relates to a method of stripping moulded plastic parts (12), for example end walls for packaging containers, in injection moulding by means of mould sections (11, 13) which together form a mould cavity. After the injection of the plastic into the mould, the mould halves (13) are opened and the moulded plastic part (12) is stripped in that gas under excess pressure is briefly aspirated in between one mould section and a portion of the plastic part (12) located in contact therewith. <IMAGE>
