Technical Field

[0001] This utility model relates to the field of injection mold parts manufacturing technology, specifically to a side-binding electrode extension electrode holder. Background Technology

[0002] Electrical discharge machining (EDM) is a crucial process in the manufacturing of injection mold parts, often required for machining parts with deep structures. To reduce the cost of electrode copper and minimize material consumption, the industry widely employs various clamping electrodes for machining operations.

[0003] However, the electrode clamping structure in the existing technology has many shortcomings: on the one hand, the clamping method of the traditional electrode holder is prone to loosening during the processing, which makes it difficult to guarantee the processing accuracy, and the positioning consistency during repeated clamping is poor, which seriously affects the processing efficiency and product quality; on the other hand, for processing scenarios with high height or deep depth, due to the structural limitations of the existing electrode holder, the machine tool head is prone to interference with the workpiece to be processed, and it is impossible to avoid the workpiece to achieve effective processing, which restricts the application of electrical discharge machining in the field of deep cavity and high-size parts.

The clamping area has at least two fastening holes, and fasteners for fixing the side-binding electrode are arranged in the fastening holes. The electrode holder body is lengthened to adapt to the processing requirements of the preset depth and avoid the machine tool head.

[0006] Furthermore, the electrode holder body includes a positioning seat, a connecting post disposed on the positioning seat and configured as an elongated structure, and a support seat disposed at the top of the connecting post. The side-binding electrode is clamped on the support seat, the positioning seat is located in the positioning area, and the support seat is located in the clamping area.

[0007] Furthermore, the lower end face of the positioning seat is provided with a first positioning pad and a second positioning pad overlapping the first positioning pad.

Detailed Implementation

[0015] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0016] like Figures 1 to 2 As shown, a side-attached extended electrode holder includes an integral electrode holder body 1. The electrode holder body 1 is elongated along the height direction and is H-shaped. The extended electrode holder body 1 adapts to the machining requirements of a preset depth and avoids the machine tool head. As the core load-bearing structure of the entire device, the electrode holder body 1 adopts an integral design, avoiding loosening or accuracy errors caused by multiple clamping, and ensuring structural stability during machining. Its elongation along the height direction can adapt to machining requirements of deeper depths (e.g., within 100mm), while the extended part forms a clearance space to prevent interference between the machine tool head and the workpiece. The overall H-shape of the electrode holder body 1 reduces the overall weight to reduce clamping burden and provides operating space for easy installation and removal of fasteners 2.

[0017] The lower end of the electrode holder body 1 has a positioning area for precise positioning between the electrode holder and the processing equipment. It is typically used in conjunction with a high-precision positioning shim to ensure consistent reference during electrode holder installation, providing a fundamental guarantee for subsequent processing accuracy. The upper end of the electrode holder body 1 has a clamping area for mounting the side-binding electrode 3. The clamping area has at least two fastening holes, each containing a fastener 2 for fixing the side-binding electrode 3. The clamping area directly clamps the side-binding electrode 3, ensuring stable electrode position during processing through close contact. The fastening holes are used to install the fastener 2, further securing the electrode and preventing electrode displacement due to vibration during processing. The fastening holes provide mounting positions for the fastener 2, which, through tightening force, firmly fixes the side-binding electrode 3 to the clamping area, ensuring no relative displacement between the electrode and the electrode holder, guaranteeing processing accuracy. The design of at least two fastening holes further enhances stability through two-point positioning. Preferably, the fastening holes are threaded holes, and the fastener 2 is a bolt.

[0018] In this embodiment, the electrode holder body 1 includes a positioning seat 10, a connecting column 11 with an extended structure disposed on the positioning seat 10, and a support seat 12 disposed at the top of the connecting column 11. The side-attached electrode 3 is clamped on the support seat 12. The positioning seat 10 is located in the positioning area, and the support seat 12 is located in the clamping area. The positioning seat 10 enables precise docking and stable installation of the electrode holder with the processing equipment. By cooperating with the positioning reference of the processing equipment through its lower end face (which can be equipped with a high-precision positioning pad), it provides stable support and accurate initial positioning for the entire electrode holder, ensuring the positional accuracy of the electrode holder during subsequent processing, which is the basis for ensuring the consistency of the processing reference. The connecting column 11 adopts an extended structure design and is a key component for realizing the "extended avoidance" function. Its length directly determines the overall height of the electrode holder, which can provide sufficient clearance space for the machine tool head and avoid interference between the head and the part when processing deep shapes. At the same time, the connecting column 11 connects the positioning seat 10 and the support seat 12 into a whole, ensuring the structural rigidity of the electrode holder body 1, preventing deformation due to force during processing, and thus ensuring processing accuracy. As the core component of the clamping area of ​​the electrode holder body 1, the support base 12 mainly serves to support and fix the side-bound electrode 3. The top surface of the support base 12 provides a fitting mounting reference surface for the side-bound electrode 3. Through the fastening holes (such as M6 screw holes) and fasteners 2 (such as M6 screws), the side-bound electrode 3 can be firmly locked on the support base 12 to prevent the electrode from shifting due to vibration or force during processing. This ensures the relative position stability between the electrode and the electrode holder, which is the key to ensuring the processing accuracy of the side-bound electrode 3.

[0019] The lower end face of the positioning seat 10 is provided with a first positioning pad 13 and a second positioning pad 14 overlapping the first positioning pad 13, and the first positioning pad body 130 and the second positioning pad body 140 are fixed to the electrode seat body 1 by bolts.

[0020] The first positioning shim 13, serving as the first layer of the positioning reference structure, corrects minor machining errors that may exist on the lower end face of the positioning seat 10 through its flatness and precision. This provides a flat and stable installation foundation for the subsequent second positioning shim 14, while also enhancing the tightness of the fit between the positioning seat 10 and the processing equipment, reducing the impact of gaps on positioning accuracy. The second positioning shim 14, which directly contacts the processing equipment, is the second layer of the positioning system, further adapting to the positioning reference surface of the processing equipment.

[0021] like Figures 3 to 4As shown, specifically, the first positioning pad 13 includes a first positioning pad body 130, arc-shaped grooves 131 formed on the four peripheral sides of the first positioning pad body 130, and a circular through hole 132 formed in the middle of the first positioning pad body 130. The first positioning pad body 130, as the main body of the first layer of positioning structure, directly contacts the lower end face of the positioning seat 10. Through its own flatness and precision, it corrects minor machining errors on the lower end face of the positioning seat 10, providing a stable installation reference for the second positioning pad 14, and serving as the basic carrier to ensure positioning accuracy. The arc-shaped grooves 131 are formed on the four peripheral sides of the first positioning pad body 130, with their center collinear with the center of the irregular groove 141. This reduces the contact area between the first positioning pad body 130 and the positioning seat 10 and the second positioning pad 14, reducing positioning deviations caused by uneven contact surfaces. Furthermore, it facilitates the operator in placing or adjusting the first positioning pad 13 using tools, improving the ease of installation and removal. The circular through hole 132 is located in the middle of the first positioning pad body 130. It can be used to avoid protruding structures (such as positioning pins) or connecting parts on the processing equipment, so as to avoid interference between the first positioning pad 13 and the equipment, while reducing the overall weight of the pad and reducing material consumption.

[0022] The second positioning pad 14 includes a second positioning pad body 140, a shaped groove 141 formed in the middle of the second positioning pad body 140, and a pad plate 142 disposed on the second positioning pad body 140 and evenly distributed within the shaped groove 141. The first positioning pad body 130 and the second positioning pad body 140 are overlapped, and the center of the arc-shaped groove 131 and the center of the shaped groove 141 are located on the same axis. The second positioning pad body 140, as the main body of the second positioning structure, directly contacts the processing equipment and overlaps with the first positioning pad body 130 to form a double positioning, further compensating for minor deviations in the reference surface of the processing equipment and improving the overall positioning accuracy. The shaped groove 141 is formed in the middle of the second positioning pad body 140, and its center is collinear with the center of the arc-shaped groove 131. It can be adapted to special positioning structures on the processing equipment (such as non-circular positioning parts) to avoid structural interference; at the same time, by reducing the material in the middle, weight reduction is achieved while ensuring positioning stability, and installation space is provided for the pad plate 142. The pads 142 are evenly distributed in the irregular grooves 141. Different thicknesses or materials of pads 142 can be selected according to processing requirements to fine-tune the overall height of the second positioning pad 14, thereby accurately compensating for the height difference between the positioning seat 10 and the processing equipment, and further improving the consistency of the positioning reference.

[0023] The first positioning shim 13 and the second positioning shim 14 are overlapped, and the arc-shaped groove 131 and the irregular groove 141 are concentric, ensuring that the positioning reference axis of the two shims coincides, avoiding positioning errors caused by center offset, and providing a unified positioning axis for the electrode holder. This structured double-layer shim design, together with the extended connecting column 11 and support seat 12 of the electrode holder body 1, forms a complete system of "precise positioning - stable support - extended avoidance". It not only ensures the consistency of the machining reference of the side-bound electrode 3 through the high-precision positioning of the double-layer shims, but also avoids the machine tool head by relying on the extended structure of the connecting column 11. At the same time, the support seat 12 fixes the side-bound electrode 3 with fasteners 2, and finally realizes efficient and precise machining of deep cavity parts, solving the problems of low positioning accuracy and large repeated clamping errors of traditional electrode holders.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
