Novel preparation process of handwork filigree

Abstract

The invention relates to a novel preparation process of handwork filigree. The novel preparation process includes the following steps that a three-dimensional size preliminary sketch is designed and input in 3D software, then a 3D printer is used for 3D printing; then a 3D finished product is cast at a time, calcined in a high-temperature furnace and then taken out; a plaster mold is taken out, aprecious metal solution is poured into the mold, the finished product is formed, then a silica gel mold is opened, a copper mold is put in a hot press, heating is carried out at the temperature of 180DEG C, silica gel is softened, the silica gel mold is cooled after the copper mold is taken out, wax is injected into the silica gel mold, a wax mold is taken out, and machine volume production of traditional filigree can be achieved; and after the finished product is made, in combination with an auxiliary 3D mold, the auxiliary mold is sleeved with the finished product, and the finished productis made into the mold shape. The whole technological process is high in implementation speed, and by means of the 3D technology, the technology precision can be higher, and the shape of the finished product also has a larger freedom degree.

Description

technical field [0001] The invention relates to the technical field of filament preparation, in particular to a novel preparation process for handmade filaments. Background technique [0002] The manufacture of filigree jewelry is a traditional Chinese handicraft. However, the traditional manufacturing methods and methods are not high in technology and low in efficiency. The Chinese invention patent CN102920116A provides a manufacturing process for metal filigree accessories and jewelry. The samples are scanned by ultrasonic waves to obtain 3D stereo rendering data; according to the obtained data, the sample is engraved on the 8407 steel plate to make the mold core; the liquid metal is introduced into the die-casting machine for die-casting to form complete filigree accessories and jewelry. However, it still has the disadvantages of poor processing accuracy and fewer types of molded products, which cannot meet the increasing requirements of modern industry for filigree techn...
