Technical Field
The utility model belongs to the technical field of electroforming device, concretely relates to negative pole mounting fixture is used in electroforming.
Background
Electroforming has many applications in the industry because of its ability to accurately replicate fine features, low process temperature, easily controllable microstructure and performance, and freedom from the limitations of the size and shape of the workpiece space. In the electroforming preparation work, the cathode fixing mode generally comprises two modes, one mode is that a cathode hanger is used for carrying the cathode and then the cathode is integrally placed in an electroforming tank for electroforming, the mode has the advantages that the cathode fixing operation is simple, the defect is that the cathode hanger is conductive metal, therefore, the surface of the hanger is electroformed with a layer of metal on the same surface of the cathode in the electroforming process, on one hand, the cathode hanger can influence an electric field, on the other hand, electroforming cation waste can be caused, and the metal plated on the surface of the cathode hanger needs to be cleaned regularly. The other cathode fixing mode is that the cathode is stuck to a cathode hanger through an insulating adhesive tape, the cathode presses the lead sheet at the same time to prevent the lead sheet from being plated with metal due to electric leakage, then the cathode hanger and the cathode are placed into electroforming solution together for electroforming, and the cathode fixing mode wastes time and labor and wastes resources, and possibly artificially introduces impurities to cause the quality of an electroforming product to be poor. Therefore, the cathode fixing clamp for electroforming is compact in structure, simple in clamping and free of electric leakage.
Disclosure of Invention
The technical scheme of the utility model is that: a cathode fixing clamp for electroforming comprises a current leading support sheet poured in pouring sealant, wherein the current leading support sheet comprises a limiting hole; the limiting hole limits a part of the bolt to be poured in the pouring sealant, and a part of the bolt is exposed outside the pouring sealant; the pouring sealant is provided with a blind hole, and the depth of the blind hole reaches the surface of the lead support chip; a silica gel pad is attached to the pouring sealant, and is provided with a positioning hole which is concentric with the limiting hole; the center of the silica gel pad is provided with a through hole; the surface of the electricity leading support sheet is fixed with an elastic electricity leading titanium sheet; the elastic electricity-leading titanium plate is positioned in the blind hole and the through hole; the bolt is matched with a gasket and a butterfly nut.
The pouring sealant is made of acid and alkali resistant materials.
The gasket, the bolt and the butterfly nut are all made of acid and alkali resistant insulating materials.
The vertical height of the elastic electricity-leading titanium sheet is higher than the sum of the blind hole and the through hole, so that the cathode can contact the elastic electricity-leading titanium sheet when being placed on the silica gel pad.
The invention has the beneficial effects.
1, the structure is compact, the occupied space is small, the clamp and the cathode can be conveniently placed in the electroforming tank, and the space of the electroforming tank is not too large.
2 the clamping and dismounting operation is simple, the butterfly nut can be screwed or loosened, and the complicated step of sticking and tearing the cathode by using an insulating tape is eliminated.
3 the sealing performance is good, no electricity leakage occurs, the cathode is tightly attached to the silica gel pad under the compression state of the gasket, and the electricity-leading sheet is located in the closed space and does not leak electricity.
