Injection device and process for plastic objects

The present invention has as its objective a device for injection moulding of preforms, or for containers in general, which overcomes the disadvantages described above, producing a simple and reliable device which can reach a high productivity level and which is economic to
These objectives of thebig plastic injection are achieved, from a first aspect of the invention, using a moulding device for plastic material objects which provides an injection mould comprising two half moulds designed to define, in its closed position, a group of injection cavities for said objects, wherein the said half moulds possess a reciprocal distancing and nearing motion defining a closed and open position, an arm for extraction from the mould of said objects provided with reversible grasping elements for the said objects
