摘要： This invention relates generally to an apparatus for casting a portion of a tire or other article of manufacture, and, more specifically, to an apparatus that has a gate design, that has a plunging nozzle with a waste reservoir for separating off-ratio material before it enters the cavity that forms a portion of the tire or other article of manufacture. The design may further include a passage that connects the runner to the waste reservoir as-well as an air vent that allows trapped gas or air to exit the waste reservoir as it fills with waste material, a valve that is operative!'/associated with the passage for closing and opening the passage at appropriate times, and a nozzle constructed from two independently translating components for initially introducing material into the waste reservoir and subsequently into the runner.

摘要： A valve gating apparatus and method for injection molding includes at least one shutter disposed between the gate and the cavity melt channel into a mold cavity. The shutter is moved laterally, between a closed position wherein flow of melt from the nozzle into the cavity is inhibited, and an open position wherein flow of melt into the cavity is unimpeded by the shutter. Intermediate these two positions, the shutter can be employed to reduce the cross sectional area of the gate to throttle the gate. Embodiments are disclosed wherein one shutter or pairs of shutters are employed to gate the gate. Further, when pairs of shutters are employed, the shutters can abut each other in the close position or can overlie each other. This novel design prevents generation of waste material and eliminates the need to have devices for removing cold plugs.
