Abstract
A mechanism for forming threads in injection molded parts includes a core member having a threaded end which is moved into and out of a mold cavity. The core member is slidably and rotatably mounted on a support and is driven by a motor through a first lost motion rotatable connection. The core member is moved linearly upon rotation thereof into the mold cavity by a lead screw member which is coupled to the core member through a second lost motion connection and threadably mounted in the support.
