Abstract
An actuator is disposed between a back plate and a manifold and is connected to a valve pin. A nozzle flange, locating ring, or pressure disc can transmit a first load between the manifold and a mold plate. A pressure disc can be disposed between the actuator and the back plate. The pressure disc transmits a second load between the back plate and the manifold through the actuator.
Claims26
An injection molding apparatus, comprising:
- a back plate;
- an actuator having a movable part connected to a valve pin and an actuator housing surrounding the movable part, the actuator housing including a cap plate disposed between the back plate and the movable part of the actuator;
- and
- a pressure disc disposed between the back plate and the cap plate of the actuator housing, the pressure disc directly contacting the back plate and the cap plate of the actuator housing, wherein the actuator is disposed between the pressure disc and a manifold.
