Abstract

Plastic part 2 is formed in a mold cavity 3 that is shown in outline in drawing A. Part 2 contains embedded electrical conductor holder 4 which is held in holes in a stationary element 5 during molding. The drawing shows a mechanism for ejecting molded part 2 from holder 4 after the molding operation is completed and mold 3 is removed.

Transverse Cam Slide Mechanism

Plastic part 2 is formed in a mold cavity 3 that is shown in outline in drawing
A. Part 2 contains embedded electrical conductor holder 4 which is held in holes in a stationary element 5 during molding. The drawing shows a mechanism for ejecting molded part 2 from holder 4 after the molding operation is completed and mold 3 is removed.

Pins 6 are carried in a part 7 and extend through holes in bar 5. Part 7 is free to slide in guides, not shown, in a direction to move pins 6 to eject part 2 and to withdraw such pins to be flush with the surface of bar 5. A pin 8 extends upward from part 7 and rides in slot 10 formed in slidable bar 11. A similar pin, not shown, extends from the bottom of part 7 and engages slot 12 in a lower bar 13 shown in drawing B. The slots are arranged so that when upper bar 11 is pushed to the left in the drawing and lower bar 13 is pushed to the right, part 7 is cammed forward to eject the molded part from bar 5. Similarly, when upper bar 11 is pushed to the right and bar 13 is pushed to the left, part 7 is cammed rearward to withdraw pins 6 to permit the next molding operation to take place.

The apparatus is particularly useful with a large number of cavities aligned side-by-side where the space for an ejecting mechanism is limited and where it is necessary to push evenly on molded part 2 to prevent bending conductors 4 as they are pushed out of the holes in bar 5.
