Abstract

PURPOSE: To improve the foundry work efficiency and to simplify a mechanism by arranging a gas chamber formed of an upper and a low plates, arranging plural ejector pins for parts extended downward from the lower side plate and projecting the ejector pins in an upper mold with the linkage.
CONSTITUTION: The gas chamber 281 closed with the plates 270, 278 connected at the interval is formed. Further, plural upper side ejector pins 280 extended downward through an opening hole part of the lower plate 278 from the gas chamber 281, are arranged. Successively, the ejector pins 280 are stroked in the opening hole parts linearly arranged in the upper mold 30 by working ejector pin operators 262, 264 arranged in a main frame 10. By this constitution, the ejection of a foundry product linked with a gas venting work, is executed. Since an upper exhaust mechanism and a gas venting manifold 32 are combinedly integrated, the foundry work efficiency is improved and the apparatus mechanism is simplified.
