One technology that has expanded the capabilities of undercut molding more than any other is the collapsible core. Rather than jumping the threads or mechanically unscrewing the parts, flexing steel collapsible cores function by collapsing radially inward during the normal mold sequence. They eliminate secondary operations and complex coring approaches while providing dramatic cycle-time reductions—often as much as 30% faster than with unscrewing mechanisms.
The segments of a collapsible core are attached to the ejector plate, while its tapered inner center pin is attached to the back of the mold. When the mold opens, the threaded outer core collapses as the ejector plate moves forward. Incorporating only three moving parts, which utilize conventional mold movements, a collapsible core enables part designs that previously would have been considered impossible to mold.
Collapsible cores are compatible with other mold components, such as two -stage ejectors and internal latch locks. These products enable positive control of both the stroke sequence and distance in two-stage ejection and of mold-plate latching operation.
•Two-stage ejectors: These adapt to a number of mold-base sizes and plate thicknesses and are available in two ejection sequences: top last and bottom last. The stroke range for each ejection stage is fixed in a simple procedure, and it cannot be tampered with or accidentally changed once installed. With internally installed components, the two-stage ejector avoids interference with waterline connectors and externally mounted components.
•Internal latch lock: This allows measured control of the mold-plate opening sequence on mold bases with stripper plates. One group of plates can be latched together while the first parting line opens. After a predetermined amount of travel, the latch lock releases the latched plates for the remaining parting line or lines to open. Like the two-stage ejector, once installed, the internal latch lock cannot be accidentally changed and does not interfere with waterline connectors or externally mounted components.
