Description

Technical Field

[0001] The utility model relates to the technical field of electroforming processing, in particular to an electroforming fixture for sign processing. Background Technique

[0002] An electroforming fixture is a special tool in the technical field of electroforming equipment. Its main function is to fix the master mold and ensure that the master mold can be stably in the electroforming solution during the electroforming process. The electroforming principle is that during the electroforming process, the master mold is fixed on the fixture as the cathode and placed in the electrolyte containing target metal ions together with the anode. By applying direct current, the metal ions on the anode move towards the cathode (i.e., the master mold) under the action of the electric field and undergo a reduction reaction on the surface of the master mold, depositing a metal layer. Finally, after reaching the required thickness, it is taken out from the electrolyte and a metal replica corresponding to the shape of the original mold can be obtained after subsequent processing.

[0003] The existing electroforming fixtures are single-group, with less production per single electroforming and slow production efficiency. When multiple electroforming fixtures are hung in the electroforming bath at the same time, it is impossible to ensure that the distance between the electroforming fixtures is equidistant. When they are unevenly distributed in the electroforming bath, the distribution of current in the plating solution will also become uneven. Uneven current will cause problems such as scorched plating or uneven plating thickness. If the distance is too close, there will be mutual interference, bubble retention, and poor plating solution flow. If the distance is too far, the capacity of the electroforming bath cannot be fully utilized, reducing the output of a single electroforming. Therefore, we propose a new type of electroforming fixture for sign processing to solve the above problems. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides an electroforming fixture for sign processing, which solves the problems that the electroforming fixture is single-group, with less production per single electroforming and slow production efficiency. When multiple electroforming fixtures are hung in the electroforming bath at the same time, it is impossible to ensure that the distance between the electroforming fixtures is equidistant. When they are unevenly distributed in the electroforming bath, the distribution of current in the plating solution will also become uneven. Uneven current will cause problems such as scorched plating or uneven plating thickness. If the distance is too close, there will be mutual interference, bubble retention, and poor plating solution flow. If the distance is too far, the capacity of the electroforming bath cannot be fully utilized, reducing the output of a single electroforming.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: An electroforming fixture for sign processing includes a support crossbar, a hook is fixedly installed at the top of the support crossbar, and an adjustable mechanism is arranged inside the support crossbar. The adjustable mechanism includes a fixed block, a bidirectional lead screw, a clamping block, and a plastic block;

[0006] Multiple groups of the fixed blocks are equidistantly and movably clamped inside the support cross bar. The bidirectional lead screw is rotationally connected inside the fixed block. The clamping block is slidably connected inside the fixed block. The clamping block is threadedly connected with the bidirectional lead screw. The plastic block is movably clamped with the clamping block.

[0007] Preferably, a template body is movably clamped inside the plastic block. A conductive sheet is fixedly installed at the bottom of the plastic block. The end of the conductive sheet abuts against the bottom of the template body.

[0008] Preferably, a chute is opened inside the fixed block. A slider is fixedly installed at the bottom of the clamping block. The slider is slidably connected inside the chute.

[0009] Preferably, a turning handle is fixedly connected to the end of the bidirectional lead screw.

[0010] Preferably, a limiting plate is fixedly installed at the top of the fixed block. A threaded rod is fixedly installed at the end of the fixed block. The threaded rod is movably clamped inside the support cross bar. A fixing bolt is slidably connected to the outer surface of the threaded rod. The fixing bolt is threadedly connected with the threaded rod. The bottom of the fixing bolt abuts against the top of the fixed block.

[0011] The utility model discloses an electroforming fixture for sign processing, and the beneficial effects thereof are as follows: By equidistantly arranging fixed blocks inside the support cross bar, the single output of electroforming is increased. The distance between the fixed blocks is equidistant, so that the template body is also equidistant, and the phenomenon of uneven distribution in the electroforming bath will not occur, which helps the uniform distribution of current in the plating solution, ensures the uniformity of the coating thickness, and meets the needs of users.

[0018] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] By providing an electroforming fixture for sign processing in the embodiments of the present application, the problems are solved that the electroforming fixture is a single group, the output of a single electroforming is less, the production efficiency is slow, for multiple groups of electroforming fixtures, when they are simultaneously hung in the electroforming bath, it is impossible to ensure that the distances between the electroforming fixtures are equidistant, and when they are unevenly distributed in the electroforming bath, the distribution of current in the plating solution will also become uneven. Uneven current will cause problems such as scorched coating or uneven coating thickness. If the distance is too close, there will be problems such as mutual interference, bubble retention, and poor plating solution flow. If the distance is too far, the capacity of the electroforming bath cannot be fully utilized, reducing the output of a single electroforming.

[0020] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0021] The embodiments of the present utility model disclose an electroforming fixture for sign processing.

[0022] According to the atta Figures 1-4 As shown in the figure, it includes a support crossbar 1. A hook 2 is fixedly installed at the top of the support crossbar 1. An adjustable mechanism 3 is arranged inside the support crossbar 1. The adjustable mechanism 3 includes a fixed block 301, a bi-directional lead screw 302, a clamping block 303 and a plastic block 304;

[0023] When the device is used, the processed template body 305 is clamped into the inside of the plastic block 304. The rotating handle 309 is rotated clockwise to drive the bi-directional lead screw 302 to rotate, so that the clamping block 303 slides towards the position of the central axis to clamp the plastic block 304. The fixed bolt 312 at the top of the fixed block 301 is unscrewed. According to the need, the number of fixed blocks 301 is selected, inserted into the inside of the support crossbar 1, and the fixed bolt 312 is tightened to complete the fixation of the fixed block 301, and then it can be placed in the electroforming bath for electroforming.

[0024] Multiple groups of fixed blocks 301 are equidistantly and movably clamped inside the support cross bar 1. A bidirectional lead screw 302 is rotatably connected inside the fixed block 301. A clamping block 303 is slidably connected inside the fixed block 301. The clamping block 303 is threadedly connected to the bidirectional lead screw 302. A plastic block 304 is movably clamped with the clamping block 303. The fixed block 301 will not be entirely immersed in the electroforming bath. Only the template body 305 is ensured to be fully immersed, so that while the template body 305 completes electroforming, the electroforming solution will not electroform the clamping components such as the bidirectional lead screw 302. The whole fixed block 301 is wrapped with high-temperature tape, so that the electroforming solution will not electroform it.

[0025] The template body 305 is movably clamped inside the plastic block 304. A conductive sheet 306 is fixedly installed at the bottom of the plastic block 304. The end of the conductive sheet 306 abuts against the bottom of the template body 305. The material of the plastic block 304 is the same as that of the high-temperature tape. Its function is to prevent the bottom and four sides of the template body 305 from being electroformed, resulting in the problem that the electroformed layer of the template body 305 is not easily removed. Through the conductive sheet 306, current can flow from the positive and negative poles of the power supply to the anode and cathode (template body 305) respectively, thus forming a complete circuit in the electrolytic cell.

[0026] A chute 307 is opened inside the fixed block 301. A slider 308 is fixedly installed at the bottom of the clamping block 303. The slider 308 is slidably connected inside the chute 307. While the slider 308 slides in the chute 307 to provide guidance for the movement of the clamping block 303, it prevents the clamping block 303 from rotating together with the bidirectional lead screw 302, thus avoiding the problem of affecting the subsequent use of the clamping member for the plastic block 304.

[0027] A turning handle 309 is fixedly connected to the end of the bidirectional lead screw 302. Rotating the turning handle 309 clockwise drives the clamping blocks 303 on both sides to clamp towards the central axis direction. Rotating the turning handle 309 counterclockwise drives the clamping blocks 303 on both sides to slide away from the central axis direction, thereby realizing the clamping and relaxation of the plastic block 304.

[0028] A limiting plate 310 is fixedly installed at the top of the fixed block 301. A threaded rod 311 is fixedly installed at the end of the fixed block 301. The threaded rod 311 is movably clamped inside the support cross bar 1. A fixing bolt 312 is slidably connected to the outer surface of the threaded rod 311. The fixing bolt 312 is threadedly connected to the threaded rod 311. The bottom of the fixing bolt 312 abuts against the top of the fixed block 301. The position of the limiting plate 310 is used to limit the position of the plastic block 304. The part below the limiting plate 310 will be immersed in the electroforming bath, providing a position limit for the installation of the plastic block 304.

[0029] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
