ABSTRACT:
A plastic injection mold having means therein for holding an insert to be secured in the formed product. A pair of complimentary sized mold sections are movable together, one mold section having a pin fixedly mounted thereto and extending toward a second pin slidably mounted in the second mold section and aligned with the first pin. In the preferred embodiment, a helical spring contacting the slidable pin urges the pin outwardly to initially hold an insert. As the mold closes, the pins are contacted together with the spring being yieldable to allow retraction of one pin and the transfer of the insert mounted thereon onto the second pin. In an alternate embodiment, the retractable pin is fixedly mounted to a movable plate having a spring loaded leg depending therefrom with the leg being contactable by the mold sections as the mold is closed for the retraction of the slidable pin and the transfer of the insert.
