Technical Field
[0001] The utility model relates to the technical field of precious metal ornaments, in particular to a diamond-encrusted ornament combining oil pressure and lost-wax casting method. Background Technique
[0002] Gold ornaments are ornaments made of gold. Gold is a precious metal and one of the earliest metals discovered and exploited by humans. It is an important raw material for making jewelry and coins and an important reserve material of the country. It is not only regarded as a symbol of beauty and wealth, but also benefits human life with its unique value.
[0003] After retrieval, the Chinese patent application number is: CN202010602309.3, which discloses an oil pressure die punching forming method for a gold pendant structure, including the steps of melting the raw materials by high-temperature casting to form a long strip-shaped casting; extruding the casting by an oil pressure press to obtain a gold sheet with specified specifications and dimensions; using a pipe-making machine to wind the gold sheet into a hollow round tube, and the diameter of the hollow round tube is larger than the pipe diameter of the product; using a pipe-pressing machine to press and synthesize the hollow round tube to obtain a gold tube with a cross-sectional diameter smaller than that of the hollow round tube; cutting off the gold tube and winding it into a gold ring pendant prototype with the required size; performing secondary extrusion on the gold ring pendant prototype by an oil pressure press to further reduce the radial dimension of the gold ring pendant prototype; and polishing and modifying the gold ring pendant prototype after secondary extrusion to obtain a gold ring pendant product. The gold ornaments made by the method of the invention have higher hardness, are not easy to wear and deform, and are more comfortable to wear.

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figure 1-2 , the present utility model provides a technical solution:
[0022] A diamond inlaid ornament combining the oil pressure method and the lost wax casting method includes the main body 1 of the ornament; the main body 1 is sheet-shaped; it includes a decorative structure provided on the main body 1; the decorative structure includes a carved surface 4 and diamonds 3 provided on the main body 1, an insert 2 is provided on the carved surface 4, and the diamonds 3 are inlaid on the insert 2.
[0023] The main body 1 is one of gold or silver. The main body 1 is made by the oil pressure method.
[0024] Furthermore, when manufacturing the main body 1 by the oil pressure method, the following steps are included:
[0025] Step 1: Material preparation
[0026] Select metal materials suitable for oil pressure production, such as gold, platinum, etc., and ensure the purity and quality of the metal materials to guarantee the quality of the final product.
[0027] Step 2: Design the model
[0028] According to the design requirements, use CAD software or draw the three-dimensional model of the metal main body 1 by hand. The model should be detailedly marked with the dimensions and shapes of each part.
[0029] Step 3: Oil pressure production
[0030] Put the metal material into the oil press and press it according to the design model. By controlling the pressure and temperature of the oil press, make the metal material form the required shape and structure. During the oil pressure process, it may be necessary to adjust and correct multiple times to ensure the accuracy of the final product.
[0031] Step 4: Post-treatment
[0032] Perform treatments such as grinding and polishing on the oil pressure formed metal main body 1 to remove the burrs and uneven parts on the surface, and ensure that the surface of the metal main body 1 is smooth and flawless. The insert 2 is one of gold or silver and has the same material as the main body 1. The insert 2 is made by the lost wax casting method.
[0033] Furthermore, when manufacturing the insert 2 by the lost wax casting method, the following steps are included:
[0034] Step 1: Make the wax pattern
[0035] Use special wax material to make the wax pattern according to the designed shape and size of the insert 2. The wax pattern should accurately reflect the details and features of the insert 2.
[0036] Step 2: Assemble the wax pattern
[0037] Assemble the made wax pattern with the metal main body 1 part, and ensure that the position and mating relationship between the wax pattern and the metal main body 1 are correct. Adhesives or other fixing methods can be used to fix the wax pattern on the metal main body 1.
[0038] Step 3: Wrap with refractory material
[0039] Wrap a layer of refractory material (such as ceramic fiber or refractory clay) around the wax mold and the metal body 1 to form an integral casting mold, ensuring that the refractory material tightly wraps the wax mold and the metal body 1 to prevent leakage of the molten metal.
[0040] Step 4: Investment casting
[0041] Pour the molten metal (such as gold, silver, etc.) into the casting mold. The molten metal will replace the position of the wax mold. After the molten metal cools and solidifies, remove the refractory material and take out the insert 2 inlaid with the metal.
[0042] Step 5: Post-treatment
[0043] Perform treatments such as grinding and polishing on the insert 2 to remove burrs and uneven parts on the surface, ensure that the surface of the insert 2 is smooth and flawless, and perfectly integrate with the metal body 1.
[0044] Among them, when specifically manufacturing the jewelry of this application, the following steps are included:
[0045] S1. Hydroforming: First, according to the design requirements, manufacture a hydroforming mold. The mold usually consists of two parts, namely the upper and lower molds. The hydroforming mold needs to have high precision and good surface finish to ensure the quality of the formed product. Then, put the gold material into the mold and apply high pressure through a hydraulic press to make the gold material fill the shape of the mold. After cooling, demold to obtain a preliminarily formed gold component.
[0046] S2. Investment casting forming: For the parts that need to inlay diamonds, use the investment casting process to manufacture the insert. First, design and manufacture the wax mold of the insert. The wax mold needs to carefully reflect the position and shape of the inlaid diamonds. Then, fix the wax mold in the gypsum powder, pour the gypsum slurry and wait for it to solidify to form a gypsum mold. The shape of the wax mold is retained in the gypsum mold. Subsequently, heat the gypsum mold, the wax mold melts and flows out to form a cavity. Heat the metal (such as gold, silver or other alloys) to the liquid state and pour it into the cavity of the gypsum mold. After cooling and solidifying, obtain the insert.
[0047] S3. Diamond inlay: Inlay the diamonds onto the insert according to the predetermined design pattern. This process may involve spot welding, bonding or other fixing methods to ensure that the diamonds are firmly attached to the insert.
[0048] S4. Combine the hydroformed part and the insert: Finally, combine the insert inlaid with diamonds and the hydroformed gold part. The combination method can be mechanical fixing, such as using snap fasteners, threaded connections, etc.; it can also be welding or bonding. Select a suitable method to ensure that the two are combined tightly and beautifully.
[0049] S5. Finishing and polishing: Use sandpaper, grinders and other tools to finish the surface, remove excess metal and burrs, and make it reach the required smoothness and appearance to complete the production of the ornament.
[0050] Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present utility model. Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present utility model.
