Abstract:
A valve for controlling the flow of fluent plastic material to a mold cavity, said valve comprising:a valve housing having a material inlet and a material outlet;an elongated valve pin axially slidably carried within the valve housing, the pin having an end adjacent the material outlet and adapted to be engaged selectively with the outlet to prevent flow of material through the valve and to be disengaged selectively from the material outlet to permit flow of material through the valve;a valve pin guide carried by the valve housing and having an opening for slidably receiving the elongated valve pin for reciprocating axial movement; anda valve pin actuator including a rotatable eccentric cam that cooperates with the valve pin at a position spaced from the end adjacent the outlet, for moving the valve pin in a direction parallel to the valve pin axis toward and away from the material outlet.
