Description

Precious metal jewelry combined by casting {Casting joined multi color ornaments}

In general, the color of precious metal ornaments are made of yellow alloys mixed with pure alloys and yellow alloys, white alloys mixed with pure gold or platinum, or white colored ornaments using silver, copper, etc. Solder a single color product, such as a red ornament made by incorporating a red alloy material, and a composite color ornament made by partially plating a portion of the single color product with a specific color, and precious metal parts of different colors. Combined precious metal jewelry

Among them, the complex color precious metal jewelry, which is made by soldering precious metal parts of different colors, has high quality, high value-added products, the manufacturing process is difficult, requires highly skilled workers, and also requires a lot of manufacturing time.

The process that has been conventionally performed for the manufacture of multi-color precious metal jewelry products in which precious metal parts of different colors are soldered together is described.

Precious metal parts M (3) and precious metal parts N (13) and precious metal parts for casting the precious metal parts M (3), precious metal parts N (13) and precious metal parts O (14) of different colors respectively by the lost wax casting method. Each master model, such as O (14), is made and each part is formed using the master models in which the internal space of the same shape as the precious metal parts M (3), precious metal parts N (13), and precious metal parts O (14) is formed. A star wax injection rubber mold is produced, and wax is injected into the wax injection rubber mold to make a wax pattern made of wax having the same shape as the precious metal parts M (3), the precious metal parts N (13) and the precious metal parts O (14), These wax patterns are buried in casting gypsum, fired in an electric furnace to remove wax, and then cast. Lost wax casting is performed by casting a precious metal material of a different color. ear The metal parts N 13 and the precious metal parts O 14 are made.

In the manufacture of multi-color precious metal jewelry products that properly arrange, assemble and solder differently colored precious metal parts produced in this way to produce a decorative effect, conventionally, precious metal parts M (3) and precious metal parts N (13) of different colors are assembled. ) And noble metal parts O (14) as shown in Fig. 2, and then soldered as shown in Fig. 3, the soldered parts are ground and smoothed, and then the jewelry is inserted as shown in Fig. 1 and polished and polished. To complete.

However, during the process of making the precious metal parts M (3), the precious metal parts N (13) and the precious metal parts O (14), the wax is cooled in the wax injection mold and shrinks and deforms during the extraction of the wax pattern from the wax injection mold. In addition, slight deformation occurs during casting by the lost wax casting method, so grinding is performed in order to ensure accurate and smooth assembly between the precious metal parts M (3), the precious metal parts N (13), and the precious metal parts O (14). It was necessary to change the assembly and soldering by using a tool, and even though it was ground and assembled like this, the interface between the precious metal parts M (3), the precious metal parts N (13) and the precious metal parts O (14) was not uniform, so the precious metals The wide gaps in the assembly interface between the parts M (3), the precious metal parts N (13) and the precious metal parts O (14) are not easily soldered and smoothly polished after soldering. Precious metal parts M (3) and precious metal parts N (13) and precious metal parts O (14) In addition to the intrinsic color of the solder, the color of the solder was revealed, which could interfere with the completeness and beauty of the product.

The present invention solves the above problems and when the precious metal parts M (3), the precious metal parts N (13) and the precious metal parts O (14) are combined, the assembly part grinding work and the soldering work are omitted, thereby improving production efficiency, In order to enable production, the casting method of the multi-colored precious metal jewelry parts, which simply combines the precious metal parts M (3), the precious metal parts Q (1) and the precious metal parts S (2) by casting, can be obtained.

In order to achieve the above object of the present invention, a wax injection rubber mold different from the conventional method should be manufactured.

The wax injection rubber mold required for the manufacture by the conventional method had to produce wax injection rubber molds for each use such as precious metal parts M (3), precious metal parts N (13), and precious metal parts O (14). Instead of wax injection rubber molds for precious metal parts M (3), precious metal parts N (13) and precious metal parts O (14), a wax injection rubber mold 12 having the same internal space as the shape of the whole parts is required.

In order to implement the present invention, the precious metal parts M (3), the precious metal parts N (13) and the precious metal parts O (14) are made precisely, and the predetermined support pins (a) on the precious metal parts N (13) and the precious metal parts O (14). ) To make the precious metal parts P (15) and the precious metal parts R (16) .The precious metal parts P (15) and the precious metal parts R (16) are assembled into the precious metal parts M (3), and the assembly boundary is epoxy. After filling and bonding with an adhesive or the like to make the whole assembly 11, a first step of manufacturing a wax injection rubber mold 12 having the same internal space as the shape of the whole parts by using the whole assembly 11 (Fig. 7). ).

At this time, since the support pin (a) is inserted into the support pin hole (c) of the wax injection rubber mold 12 having a shape in which all the parts are coupled, it is used to fix the positions of the precious metal parts Q (1) and the precious metal parts S (2). The shape and the number of the support pin (a) may be changed as shown in Figure 9 as necessary.

The wax injection rubber mold 12 having the shape in which the whole parts are combined is cut in half, and the whole assembly 11 is pulled out, and then the heat is applied to the whole assembly 11 to burn off the adhesive and the precious metal parts P (15) and the precious metal parts R (16) the precious metal parts Q (1) having been separated and soldered to the interface where the precious metal parts P (15) and the precious metal parts R (16) are assembled with the precious metal parts M (3), respectively; Step of manufacturing precious metal parts S (2)

At this time, the coupling protrusion (b) is for the purpose of improving the bonding strength when casting and joining the precious metal parts Q (1), the precious metal parts S (2) and the precious metal parts M (3). Can be changed as shown in FIG.

Each of the wax injection rubber molds for casting the precious metal parts Q (1) and the precious metal parts S (2) is manufactured in a conventional manner, respectively, and the precious metal parts Q (1) and the precious metal parts are manufactured using the respective wax injection rubber molds. Casting S (2) from Precious Metals of Different Colors

The precious metal parts Q (1) and the precious metal parts S (2) are cast into the wax injection rubber mold 12 having the same internal space as the shape in which the whole parts are combined. Inserted into the support pin hole (c) on the basis of the support pin (a) and fixed as shown in FIG. 6 and injected with wax, wax and precious metal part Q (1), the wax bonded body (10) combined with the precious metal part S (2) Steps to get

The wax binder 10 thus obtained is embedded in a metal flask 8 by casting gypsum 9 and cast by a lost wax casting method after casting by an electric furnace, as shown in FIG. 12.

Removing the support pin (a) from the composite-colored precious metal jewelry castings obtained by casting as described above, inserting the jewelry (4), and then performing polishing and polishing operations to complete the multi-colored precious metal jewelry products.

The jewelry produced during the manufacturing of the composite-colored precious metal jewelry bonded by the present invention has a holding temperature of 650 when casting a gypsum mold, which is a general casting condition of the precious metal cast by the lost wax casting method. -700 Precious metal parts Q (1) and precious metal parts S (2) in the buried gypsum were maintained at this temperature, and the wax surrounding the precious metal parts Q (1) and precious metal parts S (2) was oxidized at high temperatures. The surfaces of the precious metal part Q (1) and the precious metal part S (2) are reduced so that 800 flows in to form the precious metal part M (3). -850 In the contact surface with molten noble metals, infiltration occurs in the intermetallic landmark surface and solidifies by combining each precious metal component Q (1), precious metal component S (2) and precious metal component M (3), and in part by Even if the binding force is insufficient, the coupling between the precious metal component M (3), the precious metal component Q (1), and the precious metal component S (2) by the coupling protrusion (b) formed in advance is such that the coupling is strong enough to eliminate the need for soldering.

For this reason, it is not necessary to solder for the joining of the precious metal parts M (3), the precious metal parts Q (1) and the precious metal parts S (2), and thus the precious metal parts M inevitably generated during the soldering process as in the conventional manufacturing method. (3) and precious metal parts Q (1) and precious metal parts S (2) due to shrinkage or deformation of the precious metal parts M (3) and precious metal parts Q (1) and precious metal parts S (2). When assembling and joining, the process of changing and assembling with the polishing tool is skipped and there is no phenomenon that solder color is revealed on the assembly interface between parts due to the deviation of the assembly gap. It can greatly improve the quality of the product, and can not only produce large-value, high value-added composite color precious metal jewelry products inexpensively, but also contribute greatly to the completeness and cost reduction of the products. .
