Closing mechanism for an injection molding machine |
摘要 |
A closing mechanism of an injection molding machine has a piston-cylinder unit to be pressurized hydraulically. Two partial strokes can be carried out in the unit, of which the first can be run through faster than the second. A displacement tube (7) extends into a main cylinder chamber (6) and into an inner cylinder chamber (4) of a piston (2) of the piston-cylinder unit. The displacement tube (7) is fastened to an end wall of the main cylinder (1) and is open at its free end. The piston (2) is designed as a plunger and is spaces on all sides from the cylinder wall (5) of the cylinder (1) of the piston-cylinder unit. The piston (2) is guided in a flanged gland (15) which is screwed to the cylinder (1).
