Patent ID: 8079843

Claim:
A self-stripping forming insert comprising in combination: a stationary portion and a movable portion, said stationary portion having a top surface, a bottom surface, an inside surface, a spring mechanism and more than one vacuum passage, said stationary portion having a plurality of openings extending therethrough from said top surface of said stationary portion to said bottom surface of said stationary portion, said stationary portion housing said movable portion, said movable portion having a top surface, a bottom surface, an outer edge, and a plurality of openings therethrough, said top surface of said movable portion having male protrusions extending from said top surface of said movable portion, said top surface of said movable portion having female intrusions depending therefrom, said bottom surface of said movable portion being generally flat, said outer edge defining the outer circumference of said movable portion, said outer edge being movably engageable with the inner surface of the stationary portion, said plurality of openings allowing a vacuum to be activated upon the top surface of the movable portion of the forming insert drawing molten plastic into and over the top surfaces of both the movable portion and the stationary portion of the forming insert to form a plastic component, said spring mechanism being internal to the stationary portion and being attached to the movable portion through the bottom surface of the movable portion, said spring mechanism being vacuum controlled and mechanically activated for moving the movable portion in an up and down motion relative to the bottom surface of the stationary portion, said spring mechanism being capable of being selectively activated to move relative to said stationary component to strip said movable portion from said plastic component.
