Description

Jewelry and its mold manufacturing method

The present invention relates to a method of manufacturing jewelry and metal molds by metal plating, and more particularly to a method of manufacturing jewelry and metal molds by metal plating in a state in which a certain mold is made of wire.

Conventionally, in order to manufacture accessories (accessory) and ornaments, etc., the first designed drawings were made by handwork, the prototype was made a mold work and mass production. In addition, the mold was made of a similar product by deforming the shape and mass-produced a similar product. The product manufactured as above was finished with artificial gemstones and other processing work after the surface treatment process such as plating of gn product which has been polished and processed.

The detailed process of manufacturing a conventional accessory or jewelry is as follows.

The first prototype is made and then a mold containing the prototype is created. Next, molten metals such as brass, tin, zinc and iron are poured into molds, cast, drawn out by extrusion, or pressed. Next, grind and attach auxiliary materials such as decorations. Next, surface treatment is performed by metal plating, and then artificial stone is attached to finish the work after finishing the product.

However, in the past, in order to make ornaments, although a prototype was produced by hand and handwork according to many shapes and forms, and a mold was produced, a large amount of time and money were required to develop the original prototype. It was designed with limited shapes and forms that were difficult to meet needs. In addition, there is a difficulty in proceeding with the process after inserting artificial stones and jewelry, etc., and could not emphasize the diversity of shapes and forms.

It is an object of the present invention to provide a method for producing jewelry having various shapes by changing metal plating conditions and electrical conditions in a circular shape.

Another object of the present invention is to make a predetermined shape using a wire and then change the conditions of metal plating and electrical conditions to produce a circle to complete the ornaments with a plurality of circles replicated by a mold having a variety of shapes and molds It is to provide a manufacturing method.

In the method of manufacturing jewelry, the wire structure, which is a skeleton of the jewelry, is plated with copper borofluoride or nickel sulfamate to change the shape of the jewelry while changing the electrical conditions from 50% to 90% of the shape and thickness of the jewelry. Forming;

Inserting the circle into the silicone rubber liquid to form a mold having the shape and shape of the intaglio; Pouring molten metal into the mold to cast prototypes of the ornament by a casting machine; Polishing and processing the replicated circles; Performing an ultrasonic alkali process once again, followed by a degreasing process and a cleaning process, followed by a blue and white copper plating process, and then performing cleaning again; Subjecting the replicated prototype to copper borofluoride, nickel sulfamate, copper lactate or nickel to obtain the remaining plating thickness of 10% to 40%; And a gold plating, silver plating or platinum plating and drying step after the washing process.

The circular work according to the invention is first constructed using a wire into a predetermined shape, as similar as possible to the finished product. Nickel or copper lactate (also known as copper sulfate) plating can then be used to create a prototype by changing the plating and electrical conditions. For example, if a nickel- or lactic acid copper plating process is performed for about 10 hours while changing the electrical and plating conditions on a wire having a circular shape, the wire having a circular shape may be formed in a hexagonal, octagonal or other shape. The diameter of the wire is preferably 0.1mm to 3mm, and a certain form of wire is hung on the rack to produce a round shape by changing the electrical and solution conditions of nickel and lactic acid copper plating from 3 hours to 200 hours. The copper lactate is copper sulfate plating is made of a mixture of copper sulfate (CuSo ₄ ) 150 ~ 250g / l and sulfuric acid (H ₂ So ₄ ) 40 ~ 100g / l, nickel plating is nickel sulfate (NiSo ₄ ) 240 ~ 450g / l, chloride It is made of a mixed solution of 30 to 60 g / l of nickel (NiCl ₂ ) and 30 to 60 g / l of boric acid (H ₃ Bo ₃ ). The thickness of the plating can be made into about 100 μm to 10000 μm or more.

Next, how to complete the ornament with the prototype produced as follows. First, after the mold is manufactured, the semi-finished product obtained by casting, drawing, or pressing by the mold may be finished with ornaments through the same process as a conventional method. In another method, the semi-finished product produced by the mold is plated to a thickness of 100 μm or more while changing the electrolytic and plating liquid conditions in the same manner as the above-mentioned prototype, and then finished to complete the ornament.

Another method of making jewelry is winding artificial stone or porcelain or other materials with a wire to form a certain shape, and then plating nickel and copper lactate for 30 to 100 hours with varying electrical and solution conditions, and then finishing plating. In this case, silver and other metal plating is performed for 30 minutes to 1 hour, and the finishing process is completed to complete the jewelry.

Since the final shape or shape of the jewelry is the same in wire structure or round shape, it can be variously changed depending on the electrical resistance value and the conditions of the plating solution. Copper borofluoride and nickel sulfamate can be plated at a thickness of 3 μm per minute and copper lactate and nickel can be plated at a thickness of 1 μm per minute. Copper borofluoride plating consists of a mixed solution of 300-450 g / l copper fluoride (Cu (BF ₄ ) ₂ ) and 100-120 g / l boric acid (HBF ₄ ). Sulfamic acid nickel plating is a mixture of nickel sulfamate (Ni (NH ₂ So ₄ ) ₂ ) 480-600 g / l, nickel chloride (NiCl ₂ ) 60-90 g / l and boric acid (H ₃ Bo ₃ ) 60-90 g / l By solution.

An embodiment of the present invention will be described with reference to the accompanying drawings.

Example 1

As shown in FIG. 1A, the wire structure 10 is formed by the schematic shape and shape of the jewelry using the wire. Next, the contaminants on the surface of the wire 10 are removed by alkaline ultrasonic waves, then degreased, subjected to a cleaning process, and subjected to a cyanide copper plating, followed by a cleaning process. Copper fluoride or nickel sulfamate (copper lactate, including nickel) plating to form a circle (12) of the ornament as shown in Figure 1b by changing the electrical conditions up to 50% to 90% of the form and thickness to be made.

The process of forming a mold with the circular shape 12 of the above-mentioned ornament is as follows.

A large number of molds are formed by inserting a circle 12 of ornaments into the silicone rubber liquid. This silicone rubber material is an inexpensive mold material and has an excellent effect of easily making a circle in an intaglio form. However, in order to manufacture a mold of a more precise shape, the metal mold can be manufactured by a conventional technique. Using one of a number of these molds produced by casting the prototype 12 of the ornaments to replicate. At this time, as a casting machine, the centrifuge shown in FIG. 2 is used, and tin and zinc are used as materials. A plurality of replicated prototypes produced through the above process are subjected to grinding and processing. Next, once again undergoes ultrasonic alkali process, degreasing process, washing process, cyanide copper plating process, and then washing process again. Then, copper fluoride, nickel sulfamate, copper lactate, or nickel plating is performed to plate the remainder (10% to 40%) of the desired plating thickness to complete the shape and shape of the jewelry. Next, after the washing process, gold plating, silver plating or platinum plating is carried out and dried. Then attach auxiliary materials, such as jewelry, to complete accessories or trinkets.

Example 2

As shown in FIG. 3A, artificial stone or gemstone 16 is wound with wire 14 to form a skeleton frame of some form. Next, the alkaline ultrasonic wave removes contaminants on the surface of the artificial stone or gem 16 and the wire 14, degreases it, and then performs a cleaning process. Next, copper fluoride or nickel sulfamate (copper lactate, including nickel) plating is formed while changing electrical conditions from 50% to 90% of the shape and thickness to form a circular shape 17 of the ornament as shown in FIG. 3B.

The process of forming a mold with the circular shape 17 of the ornament is as follows.

As shown in FIG. 4, a plurality of molds 20 are formed by inserting a circle into the silicone rubber liquid. However, in order to manufacture a mold of a more precise shape, the mold 20 may be manufactured by a conventional technique. As shown in FIG. 4, the mold 20 is divided in half so that the artificial stone or jewelry 16 can be inserted into the mold 20. The artificial stone or gem 16 is placed in the half of the mold 20, the other side of the mold 20 is covered, and the molten metal of zinc or tin is poured through the spout 19 and cast into a circle of ornaments. (17) can be duplicated. At this time, as a casting machine, the centrifuge shown in FIG. 2 is used, and tin and zinc are used as materials. A plurality of replicated prototypes 17 produced through the above process are subjected to a grinding and processing process. Next, once again undergoes ultrasonic alkali process, degreasing process, washing process, cyanide copper plating process, and then washing process again. Next, copper borofluoride, nickel sulfamate, copper lactate or nickel plating is performed to plate the remainder (10% to 40%) of the desired plating thickness to complete the form of the jewelry 18 as shown in FIG. 3D. Next, after the washing process, gold plating, silver plating or platinum plating is carried out and dried.

Example 3

It is not necessary to make a mold to make jewelry. In particular, when the jewelry is small or the structure of the wire is fine, it can be carried out only by plating rather than a mold. In other words, the wire structure or the wire structure into which artificial stones are inserted is removed by decontamination of the surface by alkaline ultrasonic waves, and then degreased. Then, plating is performed for 10 to 200 hours while changing the electrical and solution conditions until the form to form copper borofluoride or nickel sulfamate (including copper lactate and nickel) plating is formed, followed by a finishing process and a cleaning process. After gold plating, silver plating or platinum plating and dried to complete the jewelry.

The present invention can easily produce ornaments that are difficult to produce a variety of circles and products by handwork and hand, and there is an excellent effect that can produce ornaments of the shape and form that cannot be produced by conventional jewelry production process.

In addition, since the present invention can produce jewelry of various shapes and shapes by changing the plating conditions, it is suitable for small quantity production of various types and has an excellent effect of satisfying the needs of various consumers.
