PURPOSE:To supply molding sand to plural molding positions with one hopper and to permit easy replenishing of the molding sand by providing a vertically moving carriage supporting the hopper at its supporting arm rotatably and vertically movably around a vertical revolving shaft. CONSTITUTION:When a vertically moving cylinder 9 is pushed while a vertically moving carriage 13 is in the lowermost end, the carriage 13 supporting a hopper 20 on the top surface of a supporting arm 15 ascends vertically while wheels 17, 19 are guided by the groove parts 7a of guiding rails 7. When the cylinder 9 is stopped at the middle, the carriage 13 stops in an arbitrary position. When a speed reduction motor 5 provided with a brake is run, a table 3 is turned together with the rails 7, the carriage 13 and the hopper 20 by a driving gear 6, a driven gear 4 and a vertical revolving shaft 2. When the hopper 20 comes to a prescribed position, the motor 5 is turned off to stop the table 3 in the prescribed position, where sand is charged into a flask in the lower part. |
