摘要： A resiliently compressible spring or cushion in an injection molding system that has:
(a) an upstream surface that engages against a complementary surface of a component of the system that transmits force between the cushion or spring and one or the other of a mount and a drive device interconnected to a valve pin ,
(b) a downstream surface that engages against a complementary surface of a component of the system that transmits force between the cushion or spring and a valve pin.
wherein the cushion or spring resiliently compresses under an upstream force (UF) exerted in response to engagement of a distal tip end of the valve pin with a gate surface.-
