Abstract

The present invention provides a metal ornament that ensures the fixing or fixing of metals to each other. In continuous lost / wax casting, the surface of the base metal is not subjected to a concave treatment, but through holes on the front and back sides are provided and cast from the back and combined. Even if the dissimilar metal of the secondary casting that appears on the surface of the base metal flows into the through hole provided in the base metal as if it was sewn into the through-hole provided in the base metal and is incorporated, It is no longer lost.

Description

The present invention relates to a metallic-made trinkets, as well as metal rings and pendants.

As a casting method for metal jewelry, there was a continuous casting method called a matte cast by the conventional lost wax method, but this method is the stage of the wax pattern that is the base when casting the base metal Thus, a concave portion into which a different metal flows when performing secondary casting is provided on the surface, and the different metal is simply fixed to the concave portion of the base metal by secondary casting.

  In general, the mating cast is simply welded between the base metal and the dissimilar metal of the secondary casting without brazing or the like.

  For example, if a conventional matching cast is used for a product such as a ring, when a shape change occurs in the base metal due to resizing, etc., between the dissimilar metal of the secondary casting that has been combined, In some cases, distortion occurred and the dissimilar metal in the secondary casting was detached from the base metal.

  As described above, in the conventional cast casting, there is an unstable case with respect to the fixation of the cast metal and the base metal after the secondary, so it is necessary to ensure the fixation or fixation of the metals.

To achieve the above object, instead of simply providing the recess on the base metal, it will open the through hole from the surface to the back surface, if such secondary casting would poured to the surface performed from the back yo rather, where the present invention is cast metal foundation and, metal jewelry this more the dissimilar metal member integrally joined to the rear surface of the該土base is cast secondarily by a metal different from the base In the base, through holes are formed in the front and back surfaces of the base, and the dissimilar metal body is cast so as to fill the through holes. The first feature is that the surface of the base is exposed at a position corresponding to the through-hole, and the present invention is a cast ring-shaped metal base, and the base is made of a different metal. A ring that is then cast and integrally joined to the back of the foundation A metal ring made of a different metal body, wherein the base is formed with through-holes opened on the front and back surfaces thereof, and the different metal body is cast so as to fill the through-holes. The second feature is that a part of the dissimilar metal body is exposed on the surface of the base at a position corresponding to the through hole, and the present invention further provides a cast metal base and the base. Is a metal pendant made of a dissimilar metal body that is secondarily cast with a dissimilar metal and integrally joined to the back surface of the base, and the base has a penetrating opening on the front and back surfaces thereof A hole is formed, and the dissimilar metal body is cast so as to fill the through hole, and a part of the dissimilar metal body is exposed on the surface of the base at a position corresponding to the through hole. Is the third feature.

As described above, according to the present invention, the secondary casting dissimilar metal flows into the through hole provided in the base metal as if it was sewn and incorporated, so the secondary casting dissimilar metal that appeared on the surface of the base metal was incorporated. The metal no longer falls off even if the shape of the base metal is changed later.

In addition, for example, if the base metal is made of platinum and the secondary casting is made with K18 , this through hole can be increased to reduce the required amount of platinum for the base metal and increase the required amount of K18, which is relatively inexpensive. For example, the material cost can be reduced with the same appearance.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a finished ring . Reference numeral 1 denotes a platinum base, and 2 denotes a dissimilar metal body, for example, K18, which is secondarily cast after the base 1 is cast and integrally joined to the back surface of the base 1 .

  FIG. 2 is a diagram for explaining a structure in the finished product by deleting a part of the finished product.

In this manufacturing process, as shown in FIG. 3, a platinum base 1 having a through hole 4 is first manufactured and cast in advance by a wax molding machine.

  Next, a tin mold 6 is welded to a silver mold 5 having the same shape as the finished product as shown in FIG. 4 to mold the silver mold 5 as shown in FIG. Make 7.

When the platinum base 1 made in advance is fitted into the silicon rubber mold 7 and then the casting wax 9 is poured, the wax bases 9 and 10 are formed on the platinum base 1 as shown in FIG. . When this is lost and wax cast at K18 and the tin road 10 made of K18 is deleted, a finished product as shown in FIG. 1 is obtained.

  FIG. 7 is a cross-sectional view when this method is applied to a pendant.

INDUSTRIAL APPLICABILITY The present invention can be used in the industrial field for producing noble metal jewelry and non-ferrous metal jewelry.
