Abstract
A wax pattern molding process, employing a mold having a cavity and a core structure in the mold cavity that include closing the mold with the core structure positioned in the mold cavity; injecting flowing heated wax into the mold to flow about the core; allowing the injected wax to cool and solidify to form the wax pattern; removing the core structure from the solidified wax pattern, while the mold holds the pattern in position in the mold; and opening the mold and removing the unencumbered wax pattern from the mold.
Claims1
A combination for use in a wax pattern molding process, employing a mold having a cavity and core pieces in the cavity, the combination comprising:
- a) a mold base and two covers removably attached to the base,
- b) the core pieces assembled together in the cavity to define with the mold a space for molding a wax pattern of a golf club head, the pieces removable one-by-one from the mold after removal of only one cover and while the wax pattern is retained in the cavity by the other cover attached to the base,
- c) the core pieces having flanges engageable against locating surfaces defined by the mold, said one cover having a first wedge that urges the flanges against said locating surfaces, when the one cover is closed on the base, the base having a wedge surface engaged by said first wedge when the cover is closed on the base,
- d) there being at least four of said core pieces, A, B, C, and D, pieces B, C and D removable after removal of said piece A, all pieces removable unidirectionally from the mold, said core pieces B, C, D having tongue and groove sliding connection to said core piece A.
