Inexpensive Spring Anchor

Forming spring anchors as hollowed bosses on castings eliminates specially machined studs normally expensively drilled and tapped into a casting.

Injecting casting material 10 around core pins 1, 2 shaped to form hollow bosses 3, 4 extending from a casting 5 eliminates all substractive machining operations. Openings 6, 7 in the bosses provide anchors for springs 8, 9 normally mounted on separately machined and fastened studs. The mold halves are open in Fig. 1 and closed in Fig. 2.
