  • Collapsible core of a mold for forming internal features such as threads
    Patent number: 9808975
    Abstract: A collapsible core of an injection mold includes relatively movable components arrayed about an imaginary centerline. When in an operational position for molding a new product, the movable components each define a separate segment of the exterior of the core, such as side by side segments of interior features such as a continuous set of threads to be formed in a product being molded. To move between operational and retracted positions, some core components are pivotally connected to a nest of the core, and others are translatably connected to the nest. When a newly molded product is ejected from the mold, ejection movement causes the pivotally connected core components to pivot to disengage the newly formed interior features, and causes the translatably connected components to translate to disengage the newly formed interior features.
