Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0025] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

It should also be understood that additional or alternative steps may be used.
[0026] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence.

Therefore, the example term "below" can include both upper and lower orientations.
[0028] Horn electrodes (also known as horn-shaped gate electrodes) are a special electrode design used in electrical discharge machining (EDM) technology, primarily for gate forming in molds. EDM technology uses pulsed discharges between the electrode and the workpiece to erode the workpiece material, enabling the machining of complex shapes. However, existing horn electrodes have separate electrode heads and connectors, requiring assembly before machining, increasing assembly time and reducing processing efficiency.
[0029] Figure 1 A schematic diagram of the electrode assembly 100 according to an embodiment of the present invention is shown. Figure 1 As shown, this utility model proposes an electrode assembly 100 and an electrical discharge machining (EDM) device. The electrode assembly 100 of this utility model includes an electrode processing component 10 and a connecting seat 20. The electrode processing component 10 includes an electrode fixing seat 12 and a plurality of first electrode heads 11. The plurality of first electrode heads 11 are spaced apart on one side of the electrode fixing seat 12. The first electrode heads 11 and the electrode fixing seat 12 are integrally formed. The connecting seat 20 is located at the top of the electrode fixing seat 12 and is used to connect with a driving component.
[0030] By using the electrode assembly 100 in this technical solution, the connecting seat 20 is used to connect the electrode assembly 100 to the driving component, so that the driving component can move the electrode assembly 100 through the connecting seat 20, thereby realizing the processing of the workpiece. The first electrode head 11 and the electrode fixing seat 12 are integrally formed, which reduces the assembly time and improves the assembly and processing efficiency of the electrode assembly 100 compared with the existing separate structure of the electrode head and electrode fixing seat 12. In addition, the motor fixing seat is provided with multiple first electrode heads 11, which can process multiple parts at the same time, improving the work efficiency.
[0031] In some embodiments of this utility model, such as Figure 1 As shown, the first electrode head 11 is a bullhorn-shaped electrode head. In this embodiment, the design inspiration for the bullhorn electrode comes from the shape requirements of the mold gate. Its unique bullhorn structure can effectively reduce the problem of insert clamping lines and improve the molding quality and efficiency of the mold. With the continuous advancement of electrical discharge machining (EDM) technology, the machining accuracy and efficiency of bullhorn electrodes have also been significantly improved, making them an important tool in the mold manufacturing field. The machining of bullhorn electrodes usually adopts a combination of CNC machining and EDM. CNC machining is used for roughing and semi-finishing of the electrode to realize the basic shape of the electrode, while EDM is used for finishing and surface treatment of the electrode to achieve high-precision shape and surface quality.
[0032] Furthermore, in this embodiment, the electrode assembly also includes a controller, which is electrically connected to a plurality of first electrode heads 11 and is used to adjust the discharge parameters of the plurality of first electrode heads 11, thereby ensuring processing consistency.
[0033] In some embodiments of this utility model, such as Figure 1 As shown, a plurality of first electrode heads 11 are spaced apart along the extending direction of the electrode holder 12. In this embodiment, the above arrangement enables the plurality of first electrode heads 11 to simultaneously contact a plurality of processing portions of the workpiece arranged along the extending direction of the electrode holder 12 when the electrode holder 12 moves toward the workpiece, thereby processing the plurality of processing portions and improving processing efficiency.
[0034] Specifically, in this embodiment, the distance between adjacent first electrode heads 11 is the same, which can correspond to multiple processing parts arranged at equal intervals, thereby accurately processing them one by one and improving reliability.
[0035] Specifically, in other embodiments of this utility model, the plurality of first electrode heads 11 may also be configured to be non-equally spaced, as long as the plurality of first electrode heads 11 correspond one-to-one with the plurality of processing parts.
[0036] Specifically, in this embodiment, the electrode holder 12 has a cylindrical structure, and the extension direction of the electrode holder 12 coincides with the axial direction of the electrode holder 12.
[0037] Furthermore, in other embodiments of this utility model, a plurality of first electrode heads 11 constitute a first electrode head group. A plurality of first electrode head groups can be provided on one side of the electrode fixing base 12. These multiple first electrode head groups are spaced apart along a first direction, enabling the electrode heads to form an array arrangement, thereby allowing for the processing of more processing parts and further improving processing efficiency. The first direction is perpendicular to the extending direction of the electrode fixing base 12.
[0038] In some embodiments of this utility model, such as Figure 1 As shown, along the arrangement direction from the electrode holder 12 to the connector 20, the orthographic projections of multiple first electrode heads 11 toward the connector 20 are located within the connector 20. In this embodiment, since the connector 20 is located directly above the electrode holder 12 when the electrode assembly 100 is in operation, placing the orthographic projections of the multiple first electrode heads 11 toward the connector 20 within the connector 20 allows the connector 20 to shield some dust or other components from falling onto the first electrode heads 11 located below the connector 20, thereby improving the reliability of the first electrode heads 11.
[0039] In some embodiments of this utility model, such as Figure 1As shown, the connecting seat 20 has a limiting groove 21 on the side opposite to the electrode fixing seat 12. The limiting groove 21 is used to connect with the driving component. In this embodiment, the driving component is provided with a protrusion, which is inserted into the limiting groove 21. When the driving component drives the connecting seat 20, the cooperation between the limiting groove 21 and the protrusion can prevent the electrode assembly 100 from moving around, thus improving the stability of the electrode assembly 100 during operation.
[0040] In some embodiments of this utility model, such as Figure 1 As shown, the limiting groove 21 is a square groove. In this embodiment, the square groove can limit the electrode assembly 100 in the direction of the electrode fixing seat 12, reduce the circumferential displacement of the electrode assembly 100 relative to the connecting seat 20, and improve the limiting capability.
[0041] In some embodiments of this utility model, the electrode processing component 10 further includes a plurality of second electrode heads, which are spaced apart on the other side of the electrode fixing base 12. In this embodiment, when the processing parts of the workpiece are located on opposite sides of the electrode fixing base 12, the plurality of first electrode heads 11 and the plurality of second electrode heads can respectively perform short-displacement processing on the processing parts on both sides, thereby improving work efficiency.
[0042] In some embodiments of this invention, the connecting seat 20 and the electrode fixing seat 12 are connected by welding. In this embodiment, the welded assembly generally has higher strength and can withstand greater loads compared to mechanical connections (such as those using bolts or rivets). Furthermore, welding offers better integration; the materials are almost fused together after welding, thus ensuring high structural stability.
[0043] In some embodiments of this utility model, the connecting seat 20 has a first connecting hole, and the electrode fixing seat 12 has a second connecting hole. The first connecting hole and the second connecting hole are detachably connected by fasteners. In this embodiment, the connecting seat 20 and the electrode fixing seat 12 can be detachably connected by bolts, which facilitates the replacement or maintenance of the electrode processing part 10 and improves the efficiency of disassembly and assembly.
[0044] Furthermore, the electrode assembly 100 of this invention adopts a structure in which first electrode heads 11 are stacked along the extending direction of the electrode holder 12, and the first electrode heads 11 adopt a bull horn-shaped contour design. By stacking, an array of first electrode heads 11 is formed to adapt to different processing scenarios. The workpiece to be processed is divided into multiple processing areas and assigned to different positions of the stacked first electrode heads 11. The discharge parameters of the first electrode heads 11 at each position are dynamically adjusted by a controller to ensure processing consistency.
[0045] This utility model also proposes an electrical discharge machining apparatus having the aforementioned electrode assembly 100.
[0046] By using the electrode assembly 100 of the electrical discharge machining apparatus in this technical solution, the connecting seat 20 is used to connect the electrode assembly 100 to the driving component, so that the driving component can move the electrode assembly 100 through the connecting seat 20, thereby realizing the processing of the workpiece. The first electrode head 11 and the electrode fixing seat 12 are integrally formed, which reduces the assembly time and improves the assembly and processing efficiency of the electrode assembly 100 compared with the existing separate structure of the electrode head and electrode fixing seat 12. In addition, the motor fixing seat is provided with multiple first electrode heads 11, which can process multiple parts at the same time, improving the work efficiency.
[0047] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
