  • Flash removal system for a mold
    Patent number: 5454708
    Abstract: A mold is equipped with a flash removal system for automatically removing flash from a molded part. A flash-retaining pin is mounted in one of the mold parts in the flash area outside of the pinch line so that flash flows around the pin during molding. When the mold opens, the molded part and the flash is retained against the mold part. An ejector pin in the mold part inside the pinch line is extendable to eject the molded part along the pinch line while the flash is retained by the flash retaining pin. The flash retaining pin can be retractable to allow the flash to drop off, or an extendable flash ejecting piston can be used to eject the flash.
