Abstract
A valve assembly for use with a part handling assembly of an injection molding machine includes a housing having a first tooling port for fluid communication with a first set of receivers on the part handling apparatus and a second tooling port for fluid communication with a second set of receivers on the part handling apparatus. First and second vacuum channels extend through the housing and are provided with respective first and second vacuum closure members to provide selective fluid communication between a vacuum source and the first and second tooling ports, respectively. First and second pressure channels extend through the housing and are provided with respective first and second pressure closure members to provide selective fluid communication between a pressurized fluid source and the first and second tooling ports, respectively. The first pressure closure member is moveable independently from the first vacuum closure member, and the second pressure closure member is moveable independently from the second vacuum closure member.
