Description

Technical Field

[0001] This utility model relates to the field of partial electroplating technology for mold cores, and specifically to a device for partial electroplating of mold cores. Background Technology

[0002] Electroplating is a process that involves electrolysis. In a salt solution containing the metal to be plated, the base metal is used as the cathode, and the plating metal or other insoluble material is used as the anode. Under the influence of an electric field, the cations of the plating metal gain electrons on the cathode surface and are reduced to metal atoms. These metal atoms accumulate on the cathode surface to form a plating layer. At the same time, the metal atoms on the anode lose electrons and become metal cations, which enter the electroplating solution to maintain a constant concentration of metal ions in the electroplating solution.

[0003] According to Chinese Patent No. CN212505134U, a local electroplating device is provided. Each lifting mechanism is evenly distributed around the electroplating tank. Lifting screws are inserted into rotating holes and rotatably connected to L-shaped support rods. The lifting screws are also inserted into threaded holes and driven by a drive block. During operation, the product to be electroplated is first clamped onto the electroplating fixture. Then, according to the portion of the product to be electroplated, the lifting screws in each lifting mechanism are rotated. Utilizing the screw principle, the rotation of the lifting screws drives the drive block to move the electroplating tank up and down along the L-shaped support rod, thereby adjusting the height of the product immersed in the electroplating solution in the tank. The electroplating fixture is connected to the cathode of an external circuit, and the anode plate is connected to the anode of an external circuit, allowing for precise local electroplating of the product. The aforementioned local electroplating device offers a simple, efficient, and low-cost process for local electroplating of the product.

[0004] In the above scheme, the local electroplating device uses an adjustable electroplating tank to adjust the height of the electroplating solution submerged in the electroplating tank of the product to be electroplated. The up and down movement of the electroplating tank may cause uneven distribution of the electroplating solution in the tank. When the electroplating tank rises or falls, the electroplating solution may flow due to the inertia of the liquid or the friction of the tank wall. This flow may cause uneven distribution of metal ion concentration in the electroplating solution. If the concentration of the electroplating solution is uneven during the electroplating process, it may lead to uneven quality of the electroplated layer, affecting the performance of the electroplated product. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a local electroplating device for mold cores, which solves the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

The anode rod and cathode rod installed inside the electroplating tank constitute the electric field required for electroplating. Through electrochemical reaction, a metal layer is deposited on the surface of the mold core to achieve the purpose of electroplating. The cleaning tank is used to clean the mold core after electroplating to remove excess electroplating solution and impurities adhering to the surface, ensuring the quality and appearance of the electroplated layer. The lifting component is used to precisely adjust the depth of the mold core in the electrolyte.

[0009] Preferably, the lifting assembly includes: two support columns, which are respectively disposed on both sides of the main body. A first mounting groove is opened on one side of each of the two support columns. A first drive motor is fixedly installed inside the two first mounting grooves.

The slider ensures the smoothness and accuracy of the moving block during the lifting process. The threaded connection between the first threaded hole and the threaded column realizes the firm connection and lifting function between the moving block and the threaded column. The third mounting slot provides installation space for the third drive motor. The third drive motor drives the rotation of the threaded rod through the rotation of the output end. Through the rotation of the threaded rod, the precise fine adjustment of the mold core in the horizontal direction can be realized, which improves the positioning accuracy and flexibility in the electroplating and cleaning process.

The limiting hole and the limiting rod are movably fitted, which plays the role of limiting the direction and distance of movement of the rectangular block. The connecting column can ensure the stability of the mechanical claw, and the mechanical claw can automatically complete the operations of grasping, lifting, moving and releasing the mold core.

[0017] Preferably, the top of the main body is provided with a placement groove and a draining groove, and a filter screen is fixedly installed inside the draining groove.

[0019] In summary, the present invention has the following main advantages:

[0020] The main body provides a stable operating platform. The moving tank facilitates the movement of the lifting component along its trajectory. The electroplating tank deposits a metal layer on the surface of the mold core through an electrochemical reaction to achieve the purpose of electroplating.

[0035] Working principle: Please refer to Figures 1-4 As shown, during use, electroplating solution is placed in electroplating tank 102 and cleaning solution is placed in cleaning tank 105. The positive electrode is connected to the anode rod 103 and the negative electrode is connected to the cathode rod 104 through an external power supply. The mold core is neatly placed in the placement tank 5. The device is connected to an external PLC controller. The PLC controller controls the start of the first drive motor 202, which drives the moving wheel 203 to rotate, so that the lifting component moves towards the placement tank 5 and moves to the top of the placement tank 5.

[0036] The PLC controller starts the second drive motor 206, which drives the threaded column 209 to rotate, adjusting the height of the rectangular block 307. The PLC controller then controls the third drive motor 304 to start, which moves the rectangular block 307 left and right, adjusting the position of the mechanical claw 311. When it moves to the appropriate position, the PLC controller controls the mechanical claw 311 to open and clamp the mold core. The PLC controller then starts the second drive motor 206 to rotate the threaded column 209, raising the rectangular block 307. At the same time, the PLC controller controls the first drive motor 202 to start, causing the lifting assembly to move the mold core towards the electroplating tank 102. When the mold core reaches the top of the electroplating tank 102, the PLC controller controls the second drive motor 206 to start, causing the rectangular block 307 to move downward and placing the mold core into the electrolyte. The location requiring local electroplating can be adjusted using the second drive motor 206 and the threaded column 209 as needed.

[0037] After electroplating, the rectangular block 307 rises, the lifting assembly moves to directly above the cleaning tank 105, and moves the rectangular block 307 downward to place the mold core into the cleaning solution for cleaning. After cleaning, the lifting assembly moves the rectangular block 307 directly above the draining tank 4. The PLC controller controls the mechanical gripper 311 to place the mold core on the filter screen 401 in the draining tank 4 for draining the cleaning solution. The above motor and mechanical gripper 311 instructions can be set by the PLC developers later. In this solution, the functional requirements can be achieved without disclosing the specific instructions.
