Cam pin/slide actuation for two-shot injection mold

In a two-shot injection mold having first and second mold sections movable between open and closed positions, the first section thereof having first and second spaced-apart sliding parts thereon, the mold including in combination:

• the first and second sliding parts each having an angled open top channel therein, with an angled bottom and opposing first and second sides forming a cam slide on the corresponding sliding part;
• at least one spring loaded protrusion extending partially into at least one of the opposite sides of each of the channels in a relaxed state thereof and depressible against spring action into the side wall of the corresponding channel;
• a first angled cam pin on the second mold section for engaging the bottom of the open top channel in the first sliding part when the first and second mold sections are moved from an open to a closed position and for passing outwardly through the open top of the channel without engaging the protrusion extending therein when the first and second mold sections move from a closed to an open position;
• a second angled cam pin spaced from the first angled cam pin on the second mold section and located to engage the bottom of the open top channel in the second sliding part when the first and second mold sections are moved from an open to a closed position, and sized to engage the corresponding protrusion to move the second sliding part perpendicularly to the movement of the first and second mold sections from a closed to a open position to open a mold cavity to facilitate removal of molded part therefrom;
• whereupon movement of the first and second mold sections from an open to a closed position causes the first and second angled cam pins to engage the bottoms of the corresponding channels in the first and second sliding parts to close the mold cavities in both of the first and second sliding parts.
