    摘要： A foundry squeeze mechanism which includes a head having a plurality of cavities within which are positioned sleeve members. Rod members are positioned in the sleeve members and are normally held in a fixed position by an interference fit between the sleeve and rod members. One end of the rod members have feet for engaging sand in a foundry flask. Fluid passage means provide for the introduction of fluid pressure between the rod members and the sleeve members at the area of the interference fit and when so introduced the sleeve members are forced outwardly releasing the interference fits. Fluid pressure or other means on the other end of the rod members causes them to be extended. Seal means are provided on each side of the area of the interference fits and stop members are provided on the rod members to limit their extended movement.
