Self-cleaning mold valve for a molding system |
摘要 |
A mold valve assembly includes a mold valve chamber having an output port and an injection chamber in communication with the mold valve chamber. A first actuator drives an injection piston within the injection chamber to drive mixture material from an inlet port into the mold valve chamber. A second actuator drives a mold valve piston along the mold valve axis within the mold valve chamber to drive mixture material through an outlet and into a mold cavity of a mold assembly. The mold valve piston closely fits within the mold valve chamber to scrape along an end segment of the injection piston to clean any mixture material remnants therefrom such that remnants within the mold valve chamber are minimized and the necessity of flushing between injection cycles is substantially eliminated.
