ABSTRACT:
A device for removal of a moulded product from a rotational moulding machine with one or a plurality of two-part moulds. The mould or moulds are movable between a closed and an open position on rotative supports in the machine frame. The removal means comprises a pair of complementary grasping elements operative to straddle each mould on either side of the mould opening zone and which can be moved towards each other at the moment when opening of the mould commences to grasp and hold the moulded product therein prior to further opening movement of the mould and to release the product therefrom. The grasping element support is operable to move from the position straddling the mould and to a position outside the machine for discharge of a moulded product, and vice versa.
