MOULD FOR MOULDED PARTS WITH INTERNAL UNDERCUTS

摘要

Mould for moulded parts with internal undercuts that comprises a core of the mould with two complementary parts (both fitted one inside the other), providing the possibility of axial displacement and turning among them, establishing the external element part various slots where the parallel forms that the internal element part has in its peripheral area are inserted. Thus, thanks to the axial displacement and the turning of both elements, the parallel forms come out of from the slots and deviate from the coping enabling the ejection of the moulded part without being forced.
