Method and apparatus for controlling a sequence of movements in a plastic material injection molding machine

An apparatus for controlling a sequence of movements in a plastic material injection molding machine having a mold with at least one movable mold portion and a movable handling means, said handling means being adapted to be moved along a predetermined trajectory and to enter between mold portions of said mold when said mold is in an open operational position, said movable mold portion having a front surface facing said handling means and defining a collision contour with respect to said handling means when being moved along said trajectory during movement of said mold portion, said handling means being adapted to pass by said collision contour after said movable mold portion has moved away from said trajectory, the apparatus comprising:

• means for moving said handling means along a first path section of said trajectory before passing by said collision contour while accelerating said handling means along said first path section up to a predetermined maximum velocity at or before reaching said collision contour for moving said handling means at said maximum velocity when passing by said collision contour;
• and
• means for deceleration said handling means along a second path section of said trajectory essentially to a standstill at a predetermined position between said mold portions.
