Problems solved by technology

[0004] But in this case, because paraffin is easy to break, the shape made of paraffin is very rough, not as fine as handmade filaments; and because of the complex structure of filigree products, a single filament is thinner, the height of the filament line is large, and there are many twisted surfaces For other reasons, making model molds is also a major difficulty; in addition, this method is not suitable for making thinner metal filaments, because the metal filaments are often interrupted during the process of crushing plaster, and the yield is low
[0005] In addition, the existing technology cannot produce large-volume metal filigree products, usually by making small pieces and then splicing them to obtain large-volume metal filigree products

Embodiment 1

[0061] Embodiment 1: A kind of manufacturing process of sterling silver filigree product

[0062] In step 1, the designer directly obtains the 3D model through computer 3D modeling. The 3D model includes the total length, width, height; the length, width, height, angle, radius of curvature of each line; size ratio, surface area, volume and other data.

[0063] Step 2, making an aluminum block (slider) model mold according to the 3D model, and installing the model mold in the injection machine.

[0064] Step 3, melting the casting wax into a liquid state, introducing it into the injection machine and injecting it into the model mold, so as to form a complete wax model of filigree products. When the model material is injected into the model mold through the injection machine, the model mold should be tightened with a pressure of 0.4MPa, and the mold release agent should be sprayed on the inner surface of the model mold.

[0065] Step 4, perform plaster mold casting

Embodiment 2

[0073] Embodiment two: a kind of manufacturing process of sterling silver filigree product

[0074] Step 1: 3D scan the prepared metal filigree product to obtain a 3D graphic, and the designer obtains a 3D model through computer 3D modeling based on the 3D graphic. The 3D model includes the total length, width, height; the length, width, height, angle, radius of curvature of each line; size ratio, surface area, volume and other data.

[0075] Step 2, making a plastic split model mold according to the 3D model, and installing the model mold in the injection machine.

[0076] In step 3, the water-soluble wax is melted into a liquid state, introduced into the injection machine and injected into the model mold, thereby forming a complete waxy model of filigree products. When the model material is injected into the model mold through the injection machine, the model mold should be tightened with a pressure of 0.4MPa, and the mold release agent should be sprayed on the inner surfac...

Abstract

The invention provides a method for manufacturing metal filament products. The method includes the step of manufacturing a filament product model; placing the filament product model into gypsum slurry and enabling the gypsum to be hardened; removing the filament product model through dissolution or fusion or gasification, forming a cavity in the gypsum, and obtaining a gypsum model; injecting metal in a fluid state into the gypsum model; and removing the gypsum after the metal is hardened, thereby obtaining the filament products. By means of the method, metal filament products with small thicknesses and large sizes can be manufactured, and metal filament products of complex structures such as large-curvature curved surfaces, surfaces with a large height difference and inner corners can also be manufactured.

Description

technical field [0001] The invention relates to a method for manufacturing metal filigree products, in particular to a method for manufacturing metal filigree products by gypsum film casting. Background technique [0002] Filigree products have a long history as an ornament, and the traditional hand-made methods are inefficient and cause huge metal loss. In recent years, a method of making filigree by die-casting has emerged. After the metal is melted, die-casting is performed under a pressure of several hundred tons to complete a complete filigree product. However, this method is immature and has high requirements for die-casting equipment, and the cost is too high. [0003] Another method is to make filigree products by gypsum mold casting. Paraffin wax is used to make the required shape of filigree products, and then put into gypsum slurry. After the gypsum solidifies, the paraffin wax is melted at high temperature, and the plaster mold is made after removing the paraffi...
