Abstract
A valve gate assembly having an actuator assembly configured to simultaneously control a plurality of valve pins to regulate flow of a liquid resin to a mold cavity of an injection molding apparatus is configured to allow fast and easy removal of the actuator assembly from the pins simultaneously by providing a valve plate having a plurality of slots or pockets for receiving and releasably holding a corresponding one of the pins.
Claims10
A valve gate assembly for an injection molding apparatus, comprising:
- a manifold having a plurality of passageways for conveying liquid resin from an injection molding machine to a mold cavity;
- a plurality of nozzles attached to the manifold, each nozzle having a longitudinal axis and a cylindrical bore extending along the longitudinal axis for conveying liquid resin from the manifold to the mold cavity;
- a plurality of valve pins, each valve pin associated with a corresponding one of the nozzles and being configured for linear movement within and along the cylindrical bore to control flow of liquid resin into the mold cavity, each valve pin having a head portion;
- an actuator having a linearly movable piston rod;
- a valve plate coupled to the rod and having a plurality of slots or pockets receiving and releasably holding a corresponding one of the plurality of valve pin heads;
- and a lock for engaging the rod and holding the valve pin heads in a fixed position in the slots or pockets;
- wherein the lock is received through an edge of the valve plate.
