The invention relates to an injection molding machine that is provided with a protective cover (15) that can be displaced from a non-protective to a protective position by means of a handle (27) and that is used to cover the injection molding nozzle during the injection process. Said protective cover is axially configured in a substantially parallel position with respect to the axis of injection (s-s) and can be displaced to a protective position. The protective cover (15) comprises a lower part (15a) on which an upper part (15b) is mounted so as to be swiveled about a substantially parallel swivel axis (a-a) with respect to the axis of injection (s-s). Said lower part (15a) and said upper part (15b) can be displaced together to a non-protective and to a protective position, thereby combining a reliable support of the protective cover with a good accessibility of the nozzle and the plastification cylinder.
La présente invention concerne une machine de moulage par injection comprenant un couvercle de protection (15) qui peut passer de la position de protection à la position de non protection, et inversement, au moyen d'une poignée (27). Ledit couvercle sert à recouvrir la buse d'injection lors de l'injection et peut passer de la position de protection à la position de non protection, et inversement, selon un mouvement axial, de manière essentiellement parallèle à l'axe d'injection (s-s). Le couvercle de protection (15) présente une partie inférieure (15a) à laquelle est fixée une partie supérieure (15b) autour d'un axe de pivotement (a-a) essentiellement parallèle à l'axe d'injection (s-s). La partie inférieure (15a) et la partie supérieure (15b) peuvent passer ensemble de la position de protection à la position de non protection, et inversement. Cela permet d'obtenir à la fois un positionnement fiable du couvercle de protection et une bonne accessibilité à la buse et au cylindre de plastification.
