Abstract:
1. A method for manufacturing a wax mold of a golf club head comprising steps of: positioning a male die assembly being composed of multiple male dies in a first cavity of a first female die to define a first gap between the male die assembly and an inner wall of the first cavity, the inner wall of the first cavity having a contour corresponding to an inner wall of the golf club head; injecting dissolvable wax into the first cavity to form a dissolvable wax mold; cooling and solidifying the dissolvable wax mold; removing the first female die to take out the solidified dissolvable wax mold; positioning the dissolvable wax mold and the male die assembly in a second cavity of a second female die to define a second gap between the dissolvable wax mold and an inner wall of the second cavity, the inner wall of the second cavity having a contour corresponding to an outer periphery of the golf club head; injecting wax for precision casting into the second cavity to form a head wax mold; cooling and solidifying the head wax mold; removing the second female die and the male die assembly to take out the solidified head wax mold; and injecting solvent into the head wax mold to dissolve the dissolvable wax mold.
