[0024] In one embodiment of the present invention, Figure 1-4As shown, a cathode cup electroplating cylinder includes a cathode cup 1, a cathode cup cover 2, a top row of pressure blocks 3 and an anode titanium basket 5; the cathode cup cover 2 is installed on the top of the cathode cup 1, and the cathode cup cover 2 is provided with a first through hole 21 and an air avoidance area 22, the first through hole 21 is located on the inner side of the inner wall of the cathode cup 1, the top row of pressure blocks 3 is installed on the cathode cup cover 2, and the top row of pressure blocks 3 is provided with a second through hole 31, and the second through hole 31 is connected with the interior of the cathode cup 1 through the first through hole 21, and the end of the anode titanium basket 5 passes through the air avoidance area 22 and is arranged inside the cathode cup 1. In this embodiment, when working, the cathode cup 1 is installed on the centrifugal electroplating machine and connected to the negative pole of the power supply. The product to be electroplated is placed inside the cathode cup 1 and injected with liquid medicine. Then, the anode titanium basket 5 is placed inside the cathode cup 1 so that the bottom of the anode titanium basket 5 is immersed in the liquid medicine of the cathode cup 1. The anode titanium basket 5 is connected to the positive pole of the power supply. The anode titanium basket is filled with anode metal. Then, the centrifugal electroplating machine starts to drive the cathode cup 1 to rotate. Centrifugal force is generated during rotation. The liquid medicine drives the electroplated product to rotate. Under the action of centrifugal force, the product will adhere to the cathode cup 1. On the inner wall of the cathode cup 1, since the cathode cup 1 is a negative electrode voltage, when the electroplated product contacts the cathode cup 1, the metal ions in the plating solution are reduced to metal ions through electrode reaction under the action of the external electric field, and metal deposition is performed on the cathode, that is, a layer of metal is electroplated on the surface of the product. Further, the centrifugal electroplating machine will stop intermittently during the rotation process, and the product will suddenly stop during the rotation process and then rotate again, in order to rearrange the moving orientation of the product so that different surfaces of the product can contact the cathode cup 1, and in the rotating electroplating process, after the solution fills the cathode cup 1, the The cathode cup cover 2 mainly plays a blocking role to prevent the medicine from overflowing, but the medicine inside the cathode cup 1 will spray out from the top row of pressure blocks 3 to the outside through the first through hole 21 and the second through hole 22. It should be noted that the injection and discharge amounts of the medicine will form a stable cycle exchange; the present application uses the cathode cup 1, the cathode cup cover 2, the first through hole 21, the air avoidance area 22, the top row of pressure blocks 3, the second through hole 31 and the anode titanium basket 5. When the cathode cup 1 is rotated, the medicine in the cathode cup 1 will be discharged to the outside through the first through hole 21 and the second through hole 31, so that it can be added while The medicine is discharged while the medicine is poured in, so that the cathode cup electroplating cylinder can work continuously for a long time without stopping the electroplating to replenish the medicine and then re-injecting the medicine, thereby achieving the effect of improving the production efficiency of the cathode cup electroplating cylinder; further, the cathode cup 1 is an integrally formed structure and is made of pure titanium. Compared with the traditional cathode cup electroplating cylinder, the present application will not cause the product to be stuck, and the product can be fully surrounded and contacted to prevent leakage of the plated product. It not only has a larger load capacity, but also a uniform current, good plating consistency, and higher efficiency.

[0026] like Figure 4 As shown, a blocking net (not shown) is provided at the bottom of the top row of pressure blocks 3. In this embodiment, the blocking net is provided at the bottom of the top row of pressure blocks 3 to prevent the electroplated product from being thrown out of the second through hole 31 or to block the second through hole 31, thereby ensuring the working stability and working reliability of the cathode cup electroplating cylinder.
[0027] like Figure 2-3 As shown, the cathode cup cover 2 is provided with a plurality of mounting grooves 23, and the plurality of mounting grooves 23 are evenly arranged along the circumferential direction of the cathode cup cover 2, and the bottom of each mounting groove 23 is respectively provided with the first through hole 21.

[0028] like Figure 1-3 As shown, each of the top row pressing blocks 3 is provided with two second through holes 32, the first through hole 21 is a waist-shaped hole, and each of the first through holes 32 is directly opposite to the two second through holes 32 of the same top row pressing block 3. In this embodiment, under the condition of ensuring that the injection and discharge amounts of the liquid medicine are kept in a stable cycle, the design size of the second through hole 32 is taken into consideration, so it is necessary to provide two second through holes 32 in each of the top row pressing blocks 3, and the first through hole 21 is set as a waist-shaped hole, so that the two second through holes 32 can be connected with the interior of the cathode cup 1 through the one first through hole 21, without the need to provide two first through holes 21, which is not only convenient for subsequent cleaning and dredging, but also improves the convenience of processing and manufacturing.
