The invention provides a wax mold structure for manufacturing a hollow diamond ring bracelet, aiming at solving the technical problems of production of the hollow diamond ring bracelets. An adopted manner is the wax mold structure for manufacturing the hollow diamond ring bracelet; the wax mold structure is an annular shape with a crescent-shaped and hollow section and a hollow structure; a diamond support mounting surface is arranged at the outer edge surface of the top of a wax mold; a coaxial supporting and positioning technological hole, which penetrates through inner and outer edges of the wax mold, is formed in the geometric center of the diamond support mounting surface; a coaxial positioning technological hole, which penetrates through two side faces of the wax mold, is further formed in a side face of the wax mold. The wax mold structure provided by the invention has the beneficial effects that the positioning technological holes for producing the wax mold are reasonably set so that batch production of the wax molds is convenient to realize; meanwhile, one part of the positioning technological holes are mounting connecting holes of the diamond ring bracelet and a diamond support, so that the wax mold structure is especially suitable for manufacturing hollow diamond rings for embedding relatively large diamonds or artificial decorative diamonds.
