Abstract
An apparatus and method for establishing triggers for the opening of one or multiple gates to a mold cavity of an injection molding system, followed by a sequence of predetermined valve pin movements over the course on an injection cycle. In one embodiment, the invention provides a graphical user interface and control system enabling a user to select from and arrange a plurality of virtual icons into a user-defined virtual sequence that define associated triggering events and actuator controlled pin movements over the course of an injection cycle. In various embodiments, the apparatus and method allows the system operator to view a simulated profile of such triggers and movements and to compare the simulated profile to an actual profile to access differences and make adjustments to the triggers and sequencing more quickly and efficiently. This is particularly useful in sequential molding systems where multiple gates need to be programmed and adjusted to compensate for variations from a predetermined sequence.
