Hollow plain gold jewelry Lulu Tong manufacturing method

Abstract

The invention discloses a hollow plain gold jewelry Lulu Tong manufacturing method. The hollow plain gold jewelry Lulu Tong manufacturing method comprises the following steps of: firstly carving a mold wax block by using a carving machine; manufacturing a corresponding silver mold by using the mold wax block; putting wax granules weighed out in the lockable silver mold and heating the silver mold; then clamping the heated silver mold on an electrical drilling machine and rotating the silver mold, uniformly distributing molten wax liquid on the inner wall of the silver mold by using rotating centrifugal force, and cooling the silver mold to obtain a hollow Lulu Tong production wax block; then putting the hollow production wax block in gypsum to manufacture a gypsum mold with a pouring gate; and finally pouring liquid gold into the gypsum mold after heating the gypsum mold and vaporizing the hollow production wax block, cooling the mold and clearing out the gypsum to obtain the hollow gold Lulu Tong. Due to adoption of the above mode, the hollow plain gold jewelry Lulu Tong manufacturing method has the beneficial effects that the hollow plain gold jewelry Lulu Tong manufacturing method can cause a production flow to be relatively simple and products to have uniform thickness and complete appearance; the weight of the products can be customized by controlling the weight of the production wax block according to the difference of weight of customized products; and the manufacturing method is convenient to operate, reduces production cost and improves production efficiency.

Description

technical field [0001] The invention relates to a method for making plain gold hollow passepartout, in particular to a production process that can make the production process simpler, and can produce production wax plates of different weights according to the customized grams. The wax plates have uniform thickness and good appearance. The production method of the plain gold hollow passepartout is complete, easy to operate, reduces production cost, and improves production efficiency. Background technique [0002] At present, most of the existing techniques for processing gold ornaments want to make Passepartout with raised reliefs, mostly adopt the method of splitting and hydraulic pressure and then welding. Although the product is bulky and light in this method, the seams are obvious and the pattern connection is not natural. , affecting the appearance of the product. In addition, due to the limitation of the hydraulic process, the product pattern cannot be guaranteed to be ...

Problems solved by technology

[0002] At present, most of the existing techniques for processing gold ornaments want to make Passepartout with raised reliefs, mostly adopt the method of splitting and hydraulic pressure and then welding. Although the product is bulky and light in this method, the seams are obvious and the pattern connection is not natural. , affecting the appearance of the product. In addition, due to the limitation of the hydraulic process, the product pattern cannot be guaranteed to be clear.

Using the pour casting process, the front process of this process is the key to pouring out the wax plate. The traditional film pouring wax cannot completely pour out the Passepartout wax plate with thin hollow walls.

If the wax is poured in pieces, and then the wax parts are welded to obtain a complete wax plate, and finally poured into a gold product, the production efficiency is not high. The wax plate increases the welding process, increases the labor cost, and also affects the appearance of the product.
