Description

Technical Field

[0001] This utility model relates to the field of mold processing equipment technology, specifically to a wire cutting device for processing molds. Background Technology

[0002] Wire EDM equipment is a commonly used tool in mold processing. It removes metal from the mold by pulsed spark discharge through an electrode wire, thereby achieving precision machining of the mold.

[0003] The existing patent document CN214264205U discloses a wire cutting device for processing molds. This utility model achieves the purpose of bidirectional movement of the mold by setting an X-axis moving stage and a Y-axis moving stage. By setting a sedimentation tank and a second filter screen, the tiny chips are separated, thereby achieving the purpose of removing tiny chips from the coolant.

[0004] However, existing wire EDM equipment for processing molds has significant shortcomings in the disassembly and cleaning of filter components. Existing wire EDM equipment separates tiny chips from the coolant through a sedimentation tank and a second filter screen, but its filter structure does not adopt a design similar to the sliding fit between the V-shaped filter frame and the side plate and side frame. The installation and disassembly process of the filter screen is relatively complicated. Due to the lack of a convenient sliding disassembly and assembly structure, when it is necessary to clean the debris on the filter screen, the operator needs to perform many tedious disassembly steps. It cannot be quickly removed by sliding along the side frame groove of the side plate like the V-shaped filter frame. This increases the maintenance difficulty of the filtration system, makes the cleaning of the filter components time-consuming, and affects the overall processing efficiency of the equipment. Utility Model Content

[0005] Technical problems to be solved The purpose of this utility model is to provide a wire cutting device for processing molds, so as to solve the problem mentioned in the background art that the existing wire cutting devices for processing molds have obvious deficiencies in the disassembly and cleaning of filter components.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a wire cutting device for processing molds, including a worktable, a mold clamping fixture is provided inside the worktable, side frames are symmetrically fixed on both sides of the inner sidewall of the worktable, a V-shaped filter frame is provided between the two side frames, side plates extend symmetrically from both sides of the V-shaped filter frame, the side plates and the grooves preset on the side frames form a sliding fit connection, and a sealing door is provided on one side of the worktable.

[0007] As a further improvement to the above solution, an adjustment rail is provided on the inner wall of one side of the workbench, and the adjustment rail is located above the side frame.

[0008] As a further improvement to the above scheme, a first slider is slidably embedded inside the first adjustment rail, and a second adjustment rail is connected to one side of the first slider.

[0009] As a further improvement to the above scheme, a guide block is fixedly connected to the end of the second adjustment rail away from the first slider. The guide block is in sliding fit with a guide groove preset on the inner side of the worktable. The second slider is slidably embedded inside the second adjustment rail.

[0010] As a further improvement to the above solution, a connecting part is integrally formed on one side of the second slider. The connecting part is connected to the mold fixture through a connecting ball shaft, and a locking handle is threaded through the top of the connecting part.

[0011] As a further improvement to the above solution, the bottom end of the locking handle can abut against the connecting ball shaft, and an adjusting screw is threaded through the middle of the upper surface of the mold fixture. The bottom end of the adjusting screw is rotatably connected to a clamping block through a bearing.

[0012] As a further improvement to the above solution, guide rods are vertically arranged on both sides of the adjusting screw on the upper surface of the clamping block, and the top of the guide rods slides through the mold clamp and extends above it.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The wire cutting equipment for processing molds achieves convenient disassembly and cleaning of the filter components by setting a V-shaped filter frame, a sliding fit structure between the side plate and the side frame, and a sealed door on one side of the worktable. The V-shaped structure can efficiently collect the debris generated during processing, and the side plate can be quickly removed by sliding along the groove of the side frame. With the protection of the sealed door, it not only ensures the cleanliness of the working environment, but also reduces the maintenance difficulty of the filtration system and solves the problem of cumbersome cleaning of filter components in traditional equipment. 2. The wire cutting equipment for processing molds achieves flexible horizontal movement of the mold fixture through the sliding cooperation of the first adjustment rail and the first slider, and the second adjustment rail and the second slider, combined with the auxiliary positioning of the guide block and the guide groove. At the same time, the connecting ball shaft between the connecting part and the mold fixture can adjust the angle of the fixture, and the locking handle can quickly fix the angle position, which greatly improves the adjustment accuracy and flexibility of the mold processing position and angle, and meets the needs of multi-angle processing of complex molds. 3. The wire cutting equipment for processing molds utilizes a cooperative structure of adjusting screw, clamping block, and guide rod on the mold clamp. Rotating the adjusting screw drives the clamping block to move vertically, while the guide rod ensures smooth movement of the clamping block. This allows for rapid and stable clamping of molds of different thicknesses. Compared to traditional clamping methods, this structure is easy to operate and the clamping force is controllable, effectively preventing the mold from loosening or shifting during processing and ensuring processing accuracy.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a wire cutting device for processing molds, including a workbench 1, a mold clamp 2 is provided inside the workbench 1, side frames 3 are symmetrically fixed on both sides of the inner side wall of the workbench 1, a V-shaped filter frame 4 is provided between the two side frames 3, side plates 5 extend symmetrically from both sides of the V-shaped filter frame 4, the side plates 5 and the grooves preset on the side frames 3 form a sliding fit connection, and a sealing door 6 is provided on one side of the workbench 1.

[0018] During the processing stage, the high-temperature electric arc generated by the wire cutting mechanism erodes the mold material. At the same time, the sprayed coolant carries metal debris down the inner wall of the workbench 1 and eventually flows into the V-shaped filter frame 4. The inclined side wall of the V-shaped filter frame 4 forms a guide slope, which causes the debris to converge to the bottom under the action of gravity and liquid flow, avoiding cleaning dead corners caused by dispersion and deposition. When the equipment is running, the sealing door 6 is attached to the workbench 1 by magnetic sealing strip to prevent coolant splashing and debris overflow, keeping the processing area clean. After processing, the operator pulls the sealing door 6 to open it around the hinge, holds the V-shaped filter frame 4 with both hands, and pulls out the side plates 5 on both sides horizontally along the preset grooves of the side frame 3. After cleaning, push them back in to complete the reset. The entire maintenance process does not require tool assistance, improving cleaning and maintenance efficiency.

[0019] An adjustment rail 7 is provided on the inner wall of one side of the workbench 1. The adjustment rail 7 is located above the side frame 3. A slider 8 is slidably embedded inside the adjustment rail 7. A second adjustment rail 9 is connected to one side of the slider 8. A guide block 10 is fixedly connected to the end of the second adjustment rail 9 away from the slider 8. The guide block 10 slides in conjunction with a pre-set guide groove on the inner side of the workbench 1. A second slider 11 is slidably embedded inside the second adjustment rail 9. A connecting part 12 is integrally formed on one side of the second slider 11. The connecting part 12 is connected to the mold fixture 2 via a connecting ball shaft 13. A locking handle 14 is threaded through the top of the connecting part 12. The bottom end of the locking handle 14 can abut against the connecting ball shaft 13. An adjusting screw 15 is threaded through the middle of the upper surface of the mold fixture 2. A pressing block 16 is rotatably connected to the bottom end of the adjusting screw 15 via a bearing. Guide rods 17 are vertically arranged on both sides of the upper surface of the pressing block 16. The top end of the guide rod 17 slides through the mold fixture 2 and extends above it.

[0020] After the wire EDM equipment for processing the mold is started, the workpiece clamping operation is performed first. The mold to be processed is placed stably on the bearing plane of the mold fixture 2. The operator rotates the adjusting screw 15 clockwise. Since the adjusting screw 15 is threadedly engaged with the mold fixture 2, its bottom end pushes the clamping block 16 vertically downward along the axis of the guide rod 17 through the bearing. The top end of the guide rod 17 slides through the mold fixture 2 to form a double-axis guide, ensuring that the clamping block 16 moves downward without swaying until it is in close contact with the upper surface of the mold. The self-locking characteristic of the thread achieves rigid clamping of molds of different thicknesses, avoiding displacement caused by vibration during processing. During lateral adjustment, the first slider 8 moves along the inner side of the first adjusting rail 7. The wall slides precisely, and the mold fixture 2 is driven to move laterally through the rigidly connected No. 2 adjustment rail 9. The sliding constraint of the guide block 10 embedded in the guide groove inside the worktable 1 eliminates the shaking during the adjustment process. The longitudinal adjustment is completed by the sliding of the No. 2 slider 11 in the No. 2 adjustment rail 9. The double-rail orthogonal design allows the mold to be finely adjusted at any coordinate position in the horizontal plane. If the processing angle needs to be adjusted, the locking handle 14 is loosened counterclockwise to release its radial pressure on the connecting ball shaft 13. At this time, the mold fixture 2 can rotate 360 ​​degrees around the connecting ball shaft 13. After the angle is calibrated, the locking handle 14 is tightened again, and the angle is fixed by the static friction force generated by the conical extrusion.

[0021] Working Principle: After the wire EDM machine for processing molds is started, the workpiece is first clamped. The mold to be processed is placed stably on the bearing plane of the mold fixture 2. The operator rotates the adjusting screw 15 clockwise. Since the adjusting screw 15 is threadedly engaged with the mold fixture 2, its bottom end pushes the clamping block 16 vertically downward along the axis of the guide rod 17 through the bearing. The top end of the guide rod 17 slides through the mold fixture 2 to form a double-axis guide, ensuring that the clamping block 16 moves downward without swaying until it is in close contact with the upper surface of the mold. The self-locking feature of the thread is utilized. The system achieves rigid clamping of molds of different thicknesses, preventing displacement due to vibration during processing. For lateral adjustment, the first slider 8 slides precisely along the inner wall of the first adjustment rail 7, driving the mold clamp 2 to achieve lateral translation via the rigidly connected second adjustment rail 9. This, combined with the sliding constraint of the guide block 10 embedded in the guide groove inside the worktable 1, eliminates shaking during adjustment. Longitudinal adjustment is achieved by the sliding of the second slider 11 within the second adjustment rail 9. The double-rail orthogonal design allows for fine-tuning of the mold at any coordinate position in the horizontal plane. If further processing adjustments are needed... To adjust the angle, loosen the locking handle 14 counterclockwise, releasing its radial pressure on the connecting ball shaft 13. At this point, the mold fixture 2 can rotate 360 ​​degrees around the connecting ball shaft 13. After the angle is calibrated, tighten the locking handle 14 again. The angle is fixed by the static friction force generated by the conical extrusion. During the processing stage, the high-temperature arc generated by the wire cutting mechanism erodes the mold material. At the same time, the sprayed coolant carries metal chips along the inner wall of the worktable 1 and eventually flows into the V-shaped filter frame 4. The inclined sidewall of the V-shaped filter frame 4 forms a guide slope, allowing the chips to pass through the filter. Under the influence of gravity and liquid flow, the liquid converges to the bottom, avoiding dead corners caused by dispersed sedimentation. When the equipment is running, the sealing door 6 is attached to the workbench 1 by a magnetic sealing strip to prevent coolant splashing and debris overflow, maintaining the cleanliness of the processing area. After processing, the operator pulls the sealing door 6 to open it around the hinge, holds the V-shaped filter frame 4 with both hands, and pulls out the side plates 5 on both sides horizontally along the preset grooves of the side frame 3. After cleaning, push them back in to complete the reset. The entire maintenance process does not require tool assistance, improving cleaning and maintenance efficiency.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
