ABSTRACT:
A device for compression moulding of plastic objects, comprising a plurality of compression-moulding units (9), each of which comprises a core mould element and a moulding cavity (2) filled by dropping into it a dose of plastic material; each moulding unit (9) is designed to carry out a moulding sequence comprising an operation of opening of the mould, an operation of filling of the moulding cavity, and an operation of closing of the mould. The device further comprises cam mechanisms for taking the moulding cavity outside of the vertical axes of the positive-mould element between the operation of opening of the mould and the operation of filling of the moulding cavity.The invention further relates to a method for the production of plastic objects by means of compression moulding device as described above.
