International Classification:
B22D 19/04, B22C 9/02, B22C 9/22, B22C 9/10
US Classification:
164 9, 164332
Abstract:
A mold usable to form a drill bit body and a method for forming such a mold are disclosed. A shell is provided, the shell having a cavity. Fusible material, such as foundry sand, is provided into the cavity, then fused to form a solid insert within the shell. The solid insert is then modified, such as by machining, to form a mold having features usable to form a drill bit body having desired characteristics. Materials for forming the drill bit body can then be provided into the mold, for heating and cooling. Then, the drill bit body and mold can be removed from the shell. The shell is thereby reusable, while the mold, being formed from inexpensive fusible materials, can be removed or destroyed, if necessary, to free the drill bit body.

US Classification:
164 97, 761084
Abstract:
A graphite core mold having its own cavity is pressed into a cavity of a graphite shell mold. The core cavity is filled with tungsten carbide, mixed with a nickel alloy, heated and then cooled to thereby provide a carbide matrix body. After milling the carbide matrix body to thereby provide a carbide bit body, the intact shell mold is removed and then used again.
