Description

stampaggio fornito da un distributore o camera calda nella camera di sovrastampaggio.
Stato della tecnica anteriore
Dal brevetto EP3323581B1 ? nota una siffatta attrezzatura di iniezione per il sovrastampaggio di un elemento anulare trilobato sulla superficie interna della prima porzione terminale
posizionata in modo che l?asse dell?elemento di stampaggio, e quindi quello della cuffia che ? coassiale ad esso, sia verticale rispetto al terreno durante il processo di sovrastampaggio
una di rezione parallela all?asse della cuffia, l?almeno una elemento anulare sagomato su una porzione di una cuffia di riparo secondo l'invenzione, rappresentata in una prima condizione operativa,
- le figure 2-6
cuffia 4. Facendo riferimento alla figura 8 tale elemento anulare 8a
materiale fuso di stampaggio Suddetta piastra mobile 3 comprende un corpo 28 ed ? mobile mediante mezzi di azionamento idraulici o elettrici, non rappresentati p
configurazione di parziale chiusura dell?attrezzatura di sovrastampaggio e di bloccaggio della cuffia 4 in cui la piastra mobile 3 ? movimentata nella sua posizione
