Sand supply port mechanism of foundry sand blowing tank in the horizontal split mold making system

摘要

PROBLEM TO BE SOLVED: To provide a sand supply port mechanism for a molding sand blowing tank in a horizontal split flask molding device which prevents sealing materials or slide gates from being worn by molding sand and prevents the molding sand from being scattered or falling outside of the sand supply mechanism.;SOLUTION: The sand supply port mechanism for a molding sand blowing tank in a horizontal split flask molding device is mainly constituted of a casing 5, slide gates 6, cylinders 7, air nozzles 8 and sealing members 9. The casing 5 is constituted of cover members 11 having a box-like casing body 10 and a sand supply opening 4. The slide gates 6 are installed freely to travel on a pair of rails 12, 12 laid on the bottom of the casing body 10 via wheels 13, 13.;COPYRIGHT: (C)2003,JPO
