Abstract
The invention relates to processes and a device for flexibly and automatically deburring and removing from moulds injection moulded workpieces seated on cores and for cleaning injection moulding tool cores and moulds, said device being used in a variety of different ways and being adaptable in a simple manner to various injection moulding tools of a variety of shapes. At least partly standardized tool units are used for adapting them to the production of various tool geometries, core clearances and similar by simply modifying the spatial arrangement of individual modular tool components to the tool units, whereby the sprue is first cut off and the front-end and longitudinal burr on the moulded workpieces are removed by translational and/or rotational movement from inside a first tool unit using grouped cutting tools, followed by the removal from the moulds of mould removal supports provided with an integrated burst protection by second tool unit whereby the burst protection is pushed o ver the workpiece before the mould removal supports, and after extraction of the workpiece or workpieces from the mould tools, they are cleaned by a third tool unit which has a roller arrangement movable in the radial and axial directions.
