Safety device for punches in a compression moulding apparatus

A safety device for an apparatus for compression-moulding objects, said apparatus comprising a moulding carousel provided with a plurality of punches and with a plurality of corresponding mould elements, each mould element being movable between a first position in which it does not interact with the respective punch and a second position in which it interacts with the respective punch for moulding an object, each punch being associated with an extracting device suitable for extracting from the respective punch a moulded object, said extracting device being operable by means of a cam track obtained in a fixed frame of said moulding carousel, wherein said cam track comprises a cam track portion that is movable between an operating position in which it interacts with said extracting device and a non-operating position in which it does not interact with said extracting device and in that a sensor is provided suitable for detecting whether, after moulding of a moulded object, the corresponding mould element returns to said first position.
