APPARATUS FOR MAKING CASTING CORES Russian patent published in 2000 - IPC

FIELD: foundry, possibly manufacture of casting cores with gas removing duct. SUBSTANCE: apparatus includes mechanism for blowing up mixture; mechanism for blowing-through cores with solidifying gas-air mixture; device for applying cementing composition on halves of molded cores with gas-exhaust duct; transporting means. In each position transporting means is provided with drive units for opening-closing halves of core boxes and for extracting cores. On plate of mechanism for blowing through with gas-air mixture there are members whose shape corresponds to that of inner gas-exhaust ducts. Blowing through plate has openings coaxial to driven pins designed for forming in cores pinholes connecting gas-exhaust ducts with atmosphere. EFFECT: enhanced efficiency, reduced energy consumption, high accuracy of casting cores with gas-exhaust duct. 8 dwg
