Powder Shoe

A rotary core press has a plurality of fill stations, each comprising powder shoe 1 for feeding powder into die cavities 2 in rotary table 3. Shoe 1 is mounted on a stationary portion of the core press and extends over the path of cavities 2.

Shoe 1 has an ejector blade 4 that deflects pressed cores 5 from table 3 and a pickup blade 6 that scoops circulating powder from the center column 7 of the table into the shoe. The powder flows between two baffles 8. The latter concentrate the powder so as to gravity fill cavities 2 as they pass beneath shoe
1. Vertically adjustable gate 9 controls the flow of powder from the fill area between baffles 8 to provide a steady, even flow of powder between adjacent fill stations. Wiping arm 10 wipes excess powder from cavities 2 and directs the powder towards column 7.

Gate 9 is mounted on lever 11 pivoted at 12. Adjusting screw 13 positions gate 9 relative to passage 14 through which powder flows at the desired rate from the fill area. Passage 14 overlies the path of movement of cavities 2.
