I like this spring.
I think I learned something.
Hi, unfortunately I cannot open it (future version).
I usually make my cosmetic spring in a part in juste one sweep, and "torsion" option. You can make external mates to animate it in an assembly.
See a sample attached.

I've seen it before on Youtube to make some movement will be fine....but any spring has natural limits by standard according to the industry you needed
SolidWorks Realistic Movement Spring - YouTube (It's cosmetic)
Animate springs in SolidWorks - YouTube (A little bit more real)
I will try to use your example in some tooling but I use only states of open or close die/tooling....
