Embodiment 1

[0032] Embodiment 1: as figure 1 As shown, a 3D hard gold process, the steps include: S1, making a master and cleaning; S2, using the master made in step S1 to make an adhesive film, and using the adhesive film to make a wax plate that can replicate the shape of the master Model, and repair; S3, apply silver oil to the wax model, hang the wax model on the workpiece fixing frame of the electroforming cylinder, so that the wax model rotates with the workpiece fixing frame during the electroforming process; S4, start the electroforming cylinder Carry out electroforming to obtain an electroforming part; S5, remove wax from the electroforming part, remove wax, fry color, and remove impurities; S6, perform mold-holding process, sandblasting process and calendering process on the semi-finished jewelry piece in step E in sequence.

[0033] Among them, the steps of making a master in S1 are as follows: S11, making 3D model data through computer software; S12, importing the prepared 3D ...

Embodiment 2

[0039] Embodiment 2: The difference between embodiment 2 and embodiment 1 is only that the content of sodium chlorophyllin is different, and the content of sodium chlorophyllin in embodiment 2 is 10g / L.

Embodiment 3

[0040] Embodiment 3: The difference between embodiment 3 and embodiment 1 is only that the content of sodium chlorophyllin is different, and the content of sodium chlorophyllin in embodiment 3 is 12.5g / L.

Abstract

The invention relates to the technical field of precious metal processing and discloses a 3D hard gold process. The 3D hard gold process comprises the steps of S1, making a master mask and washing themaster mask; S2, using the master mask made in the step S1 to make a glue film, using the glue film to make a wax mould capable of copying the appearance of the master mask, and repairing the wax mould; S3, coating silver oil to the wax mould, hanging the wax mould on a workpiece fixing rack of electroforming cylinder so that the wax mould rotates with the workpiece fixing rack in the electroforming process; S4, starting the electroforming cylinder to perform electroforming so as to obtain an electroforming part; S5, forming a wax in the electroforming part, removing wax, enhancing the glossof the electroforming part and removing impurities from the electroforming part; and S6, carrying out a finishing process, a sand-blasting process and a calendaring process on a jewelry semi-finishedproduct in the step 5 in sequence. According to the 3D hard gold process, as the master mask is washed after being made and impurities in the master mask are removed, the accuracy and quality of the electroforming part are obviously improved.

Description

technical field [0001] The invention relates to a 3D hard gold process, which belongs to the technical field of precious metal processing. Background technique [0002] 3D hard gold is mainly produced by electroforming. Put the master plate in the electroforming cylinder, and as the electroforming proceeds, an electroformed layer is formed on the master plate, which is the 3D hard gold layer, and finally the master plate is taken out to form 3D hard gold. In actual processing, impurities are often carried on the master plate, and the impurities carried on the master plate will affect the accuracy of the wax mold, thereby affecting the accuracy of 3D hard gold. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a 3D hard gold process, which cleans the master plate, thereby increasing the precision, purity and hardness of the 3D hard gold workpiece after processing. [0004] The above technica...
