PROBLEM TO BE SOLVED: To surely exhaust gas, etc., from an exhausting hole, etc., in a molding flask by providing a fixed mold exhausting and supplying mechanism having an engaging means engageable with one side of engaging part of the molding flask, pattern plate, etc., and a movable mold exhausting and supplying mechanism having an engaging means engageable with the other side of engaging part of the molding flask, pattern plate, etc. SOLUTION: A movable supporting member, etc., in each fixed mold exhausting mechanism 6 is positioned to each molding flask 1 and a cylinder is extension-worked, and each first exhausting means is abutted on each first exhausting hole to suck and exhaust the air in each molding flask 1. Successively, a second exhausting means in each movable mold exhausting mechanism 26 is positioned just above a second exhausting hole in each molding flask 1 and abutted on each second exhausting hole by extension-working a cylinder to exhaust the air in each molding flask 1. The exhaust with a first exhausting means is stopped and the molding flask group 3 is shifted to the right side by one flask length, and at the same time, a second holding mechanism, the second exhausting means, etc., of plural movable mold exhausting mechanisms 26, 26 are synchronously shifted to the right side by one molding flask length. |
