COMBINED MOULDING, METHOD AND DEVICE FOR ASSEMBLING PLASTIC ARTICLES TO BE HINGED ON EXTRACTION FROM MOULD Russian patent published in 2011 - IPC B29C45/14 B65D25/32 B29C45/26 

FIELD: process engineering.

SUBSTANCE: invention relates to moulding plastic articles. Moulded article comprises first part 10 with hinge pin 14 and second part 11 with pin element 15 to be pivoted together. Proposed device comprises injection mould 20, 21 with cavities for mould two aforesaid parts of described article 10, 11. First moulding element 40 making pin cavity 14 and second moulding element 41 making ring element cavity 15 may axially move and are coupled with can actuators 46, 47. Said actuators make components of injection mould. Cam actuators 46, 47 feature shape and arrangement to allow automatic assembly of moulded parts after closure of mould 20, 21 by means of axial displacement of two moulding elements 40, 41 in extraction of moulded article from mould.

EFFECT: shorter working cycle, automatic assembly of moulded components.
