Technical Field
[0001] The utility model relates to the technical field of mold processing, and particularly relates to a multi-piece alloy mold core batch tooling fixture. Background Technique
[0002] The mold core, also known as the mold cavity or mold core, is the main fixed forming part in the mold. It is a model manufactured according to the product design, and its shape and size accurately reflect the internal structure of the final product. During the manufacturing process, the molten material is injected into the mold, and the mold core is responsible for guiding and restricting the flow of these materials, so as to obtain the required product shape.
[0003] In the processing and manufacturing of alloy mold cores, wire electrical discharge machining is required. However, traditional fixtures can often only process a single mold core and cannot meet the needs of batch production. This not only increases the frequency of adjusting the fixture, reduces production efficiency, but also increases the loss of the electrode wire, resulting in an increase in production costs. Therefore, in view of the above problems, we propose a multi-piece alloy mold core batch tooling fixture. Content of the Utility Model

[0025] The present utility model provides a multi-piece alloy die core batch fixture. Please refer to Figures 1 to 3 , which includes a fixture main body 1, a limiting rod 2 arranged in the fixture main body 1, a plurality of fastening bolts 3 arranged on one side of the fixture main body 1, and a workpiece 4 arranged in the fixture main body 1; the fixture main body 1 includes a plurality of clamping grooves 101, limiting holes 102 arranged at the bottom of the clamping grooves 101, structural seams 103 arranged above the limiting holes 102, and threaded holes 104 arranged on one side of the clamping grooves 101.
[0026] The workpiece 4 is respectively placed in the clamping groove 101. The shape of the opening of the clamping groove 101 is consistent with the cross-section of the workpiece 4. The workpiece 4 can be placed into the clamping groove 101 through the opening and can slide in the groove. The number of the clamping grooves 101 is the same as that of the fastening bolts 3 and they correspond to each other. The fastening bolt 3 is threadedly connected to the threaded hole 104 and is used to fasten the workpiece 4. The limiting hole 102 communicates with the structural seam 103. The structural seam 103 penetrates 50% - 60% of the fixture body 1. The limiting rod 2 can be inserted into the fixture body 1 by fitting with the limiting hole 102 and is used to limit the insertion height of the workpiece 4. The workpiece 4 includes limiting blocks 401 fixed on both sides thereof. The limiting blocks 401 abut against the clamping groove 101, and the position of the workpiece 4 can be fixed by tightening the fastening bolt 3. The workpiece 4 further includes a processing area 402 provided on one side of the fixture body 1.
[0027] It should be noted that the overall fixture is made of H13 die steel, and the specific material is 4Cr5MoSiV1. Its chemical composition is as follows: carbon (C): 0.32 - 0.45%, silicon (Si): 0.80 - 1.20%, manganese (Mn): 0.20 - 0.50%, sulfur (S): ≤0.030%, phosphorus (P): ≤0.030%, chromium (Cr): 4.75 - 5.50%, vanadium (V): 0.80 - 1.20%, molybdenum (Mo): 1.10 - 1.75%. As a kind of high-speed tool steel, the fixture made of this material has excellent wear resistance, heat resistance and corrosion resistance. It can withstand a large impact force during use and can maintain a long service life, which is very suitable for the use environment of the fixture.
[0028] Preferably, in this embodiment, the processing methods of the fixture can be divided into medium-speed wire cutting processing and manual tapping processing. The clamping groove 101, the limiting hole 102 and the structural seam 103 are processed by medium-speed wire cutting to ensure the processing dimension accuracy, improve the clamping stability of the fixture to the mold core, and ensure the consistency of the products. The threaded hole 104 is processed by manual tapping, which is economical, efficient and has strong adaptability.
[0029] Preferably, the structural seam 103 can effectively disperse and reduce the stress concentration generated during the use of the fixture, thereby reducing the risk of fatigue damage of the material. Moreover, in some high-temperature working environments, the fixture will deform due to thermal expansion. The structural seam 103 can provide a certain amount of movement space, allowing the material to expand freely when heated, preventing deformation or damage caused by thermal expansion. In addition, since the structural seam 103 communicates with the limiting hole 102, the structural seam 103 can also facilitate the insertion of the limiting rod 2 into the limiting hole 102 and reduce friction.
[0030] Preferably, the cross-sections of the limiting rod 2 and the limiting hole 102 are both circular because the shape of the cylindrical limiting rod is simple and convenient for processing and manufacturing. In other embodiments of the present invention, the limiting rod 2 can also be selected to be polygonal or groove-shaped and adjusted according to the supporting shape of the workpiece 4.
[0031] Preferably, in this embodiment, the workpiece 4 is an alloy mold core of a certain shape. During the actual production process, the shape of the clamping groove 101 of the fixture can be adjusted according to the shape of the mold core to be processed, so as to better adapt to alloy mold cores of different shapes, improve the stability and accuracy of processing, and avoid displacement or vibration during processing.
[0032] During use, first fix this fixture on the processing workbench, pass the limiting rod 2 through the fixture through the limiting hole 102, loosen all the fastening bolts 3, then insert the workpiece 4 into the fixture along the clamping groove 101 respectively until the bottom of the workpiece 4 abuts against the limiting rod 2. Finally, fasten them in sequence. Manually press the workpiece 4 while tightening the fastening bolts 3 to firmly clamp the workpiece 4 side by side on the fixture, and then start the wire electrical discharge machining of the workpiece 4.
[0033] In summary, the multi-piece alloy mold core batch tooling fixture of the present invention can clamp multiple mold cores at the same time, so as to complete the cutting of multiple mold cores in one processing, enabling the electrode wire to be more efficiently utilized during processing, reducing losses and thus saving costs, and significantly improving production efficiency; moreover, since multiple mold cores can be processed, the number of adjustments required by the operator when using the fixture is greatly reduced, reducing the errors caused by fixture adjustment and improving the machining accuracy of the mold core. In addition, processing multiple mold cores in the same batch can ensure the consistency and quality stability of the products and reduce the differences that may occur in single-piece processing.
[0034] The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the art of the present invention based on the above disclosure shall fall within the protection scope of the claims.
