Abstract
An injection casting apparatus for the manufacture of multiple layer shoe soles in a multiple element mold (11). The bottom of each mold is closed by one of two bottom stamps (14, 15) disposed on the ends of support arms (23, 24) which are mounted about an inclined axis of rotation (42). The bottom stamp not in use is directed radially outward from the apparatus to improve servicing and cleaning. The bottom stamp in use is centered above a raising and lowering device (37) which moves the stamp into operating position to close the mold and away therefrom to rotate the stamps. This centered arrangement prevents any torque from arising in the bottom stamp during use.
