Abstract

L'invention concerne une machine de moulage par injection grâce à laquelle l'espace de collecte de résine d'injection d'ébauche sous la buse d'injection n'est pas nécessaire et la course du cylindre d'injection peut être raccourcie. Sous la buse d'injection (30) se trouvent une pièce d'aspiration de résine (4a) et une pièce de formation d'un flux d'air (4b) pour changer la direction d'évacuation de la résine évacuée de la buse d'injection (30) par courbure de la direction d'évacuation vers la pièce d'aspiration de résine (4a). La récupération continue de résine directement de la buse d'injection (30) à l'aide d'un flux d'air élimine le besoin d'un récipient ou d'un espace pour collecter la résine sous la buse d'injection (30) et raccourcit la course de déplacement du cylindre d'injection (31).
