Abstract
A golf club head wax pattern molding process, employing a mold having a first cavity and cores in the mold cavity, including closing the mold with the cores positioned in the mold cavity, certain of the cores slidably interfitting endwise; injecting flowing heated wax into the mold to flow about the cores; allowing the injected wax to cool and solidify to form the wax pattern; removing the cores from the solidified wax pattern, while the mold holds the pattern in position in the mold, by endwise removing the cores in sequence; and opening the mold and removing the unencumbered wax pattern from the mold.

In a golf club head wax pattern molding process, employing a mold having a first cavity and cores extending endwise in the first cavity, the steps that include
- a) closing the mold with the cores positioned in the first cavity, certain of the cores slidably interfitting endwise,
- b) injecting flowing heated wax into the first cavity to flow about the cores,
- c) allowing the flowing heated wax to cool and solidify to form the wax pattern,
- d) removing the cores from the wax pattern, while the mold holds the wax pattern in position in the mold, by endwise removing the cores in sequence,
- e) then opening the mold and removing the wax pattern from the mold,
- f) providing the mold to have a body and first and second covers, and locating said first cavity to be covered by the second cover,
- g) providing a second cavity in the mold,
- h) and the first cavity formed in the shape of a golf club head, and the second cavity formed in the shape of a golf club head sole plate being kept closed by the second cover during step d), after opening of said first cover,
- i) allowing some of the flowing heated wax to flow to the second cavity, there being an additional core, for the wax pattern for the sole plate, carried by the second cover,
- j) and wherein the cores comprise multiple core pieces, and step d) includes removing the core pieces from the wax pattern in the mold, in a manner such that the pattern becomes a hollow shell supported in and by the mold,
- k) the core pieces having ends that define the interior configuration of a golf club head,
- l) and wherein said core pieces are removed from the wax pattern via that portion of the wax pattern which defines an opening which corresponds to a position of said golf club head sole plate to be separately attached to a cast golf club head, and molding a wax pattern of the sole plate in the mold at the same time that said steps b) and c) are carried out.
In a golf club head wax pattern molding process, employing a mold having a first cavity and cores extending endwise in the first cavity, the steps that include
- a) closing the mold with the cores positioned in the first cavity, certain of the cores having endwise elongation and slidably interfitting endwise,
- b) injecting flowing heated wax into the first cavity to flow about the cores,
- c) allowing the flowing heated wax to cool and solidify to form the wax pattern,
- d) removing the cores from the wax pattern, while the mold holds the wax pattern in position in the mold, by endwise removing the cores in sequence,
- e) and then opening the mold and removing the wax pattern from the mold,
- f) the mold having a second cavity and an associated core therein to form a golf club head sole plate pattern, and including the step of allowing some of said flowing heated wax to flow to the second cavity,
- g) the mold including a body and first and second covers to cover different portions of the body,
- h) step d) including opening the first cover to allow removal of the cores from the wax pattern for the head, while the second cover remains closed, and while the wax pattern for the head remains positioned in the mold, and also while the wax pattern for the sole plate remains positioned in the mold,
- i) said associated core for the wax pattern for the sole plate being carried by said second cover,
- j) the cores comprising multiple core pieces, and step d) includes removing the core pieces from the wax pattern for the head in the mold, in a manner such that the wax pattern for the head becomes a hollow shell supported in and by the mold, the core pieces being removed one by one, and unidirectionally,
- k) step e) including opening the second cover to allow removal of the wax pattern for the head from the mold, and then removing said wax pattern for the head.

- k) the core pieces having bulbous ends that define an interior configuration of a golf club head,
- l) and wherein said core pieces are removed from the wax pattern for the head via that portion of the wax pattern for the head which defines an opening which corresponds to the position of said golf club head sole plate to be separately attached to a cast golf club head, and molding the wax pattern of the sole plate in the mold at the same time that said steps b) and c) are carried out.
