[0003] For example, the announcement number is: CN218168991U (named a wire cutting fixture for mold manufacturing), which includes a bottom plate, the top side of which is fixedly connected to a vertical plate 1 and a vertical plate 2, the left side of the vertical plate 1 is rotatably connected to two bidirectional screw rods, and the two bidirectional screw rods are both rotatably connected to the left side of the vertical plate 2, the outer side spiral transmission of the two bidirectional screw rods has two spiral blocks, the top sides of the two spiral blocks are rotatably connected to two card blocks, the left side of the vertical plate 1 is fixedly connected to a motor, and the output shaft of the motor and the outer sides of the two bidirectional screw rods are fixedly sleeved. There are sprockets, and the outer sides of the three sprockets are meshed and connected with the same chain. By setting a clamping block, the two spiral blocks will move inward equidistantly at the same time under the transmission of the bidirectional screw rod, and the four clamping blocks can cooperate to clamp the workpiece. When encountering a circular workpiece, the four clamping blocks will rotate inward according to the curvature of the edge of the circular workpiece. After rotation, the four clamping blocks are grouped in pairs to form two V-shaped angles to clamp the workpiece, and the clamping effect can still be guaranteed, thereby avoiding the trouble of disassembling and assembling different fixtures, thereby saving a lot of processing time and improving processing efficiency.

[0004] The above-mentioned wire cutting fixture positions the mold through a clamping mechanism, but the clamping slot size of the clamping mechanism is limited and cannot clamp molds of different sizes, resulting in a large limitation of the fixture. To this end, we provide a wire cutting fixture for mold manufacturing. Utility Model Content

[0036] Working principle: When in use, place the mold that needs to be processed by wire cutting on the placement table 2, so that the position that needs to be wire cut is above the cutting groove 19, and then push the two movable carriers 9 to make the two clamping blocks 10 abut against the outer walls of the two sides of the mold, then press the switch 5, so that the power box 4 supplies power to the two electromagnets 16. After the two electromagnets 16 are powered, they generate magnetic force to attract the two connecting bases 13, thereby positioning the position of the movable carrier 9 and the clamping block 10, improving the stability of the clamping, and then drive the concave plate through the electric push rod 3. 7 is raised and lowered, and the positions of the two pressing rods 12 are adjusted through the active connection between the top block 22 and the guide slot 21. The electric push rod 3 drives the concave plate 7 and the pressing rod 12 to descend, so that the pressing rod 12 is abutted against the top position of the mold through the clamping pressure head 23, thereby applying a vertical clamp to the mold while clamping horizontally. Both the horizontal clamping and the vertical clamping can be adaptively adjusted, thereby making the clamp suitable for use with molds of different sizes, improving the versatility of the clamp, and completing the use of the wire cutting clamp for mold manufacturing.
