[0031] The technical solutions of the present utility model will be further described below with reference to the accompanying drawings and through specific embodiments.

[0032] As Figures 1 to 5 shown, the embodiment of the present utility model provides a vise fixture for mold processing, including a base 1, a universal rotation assembly 2, a top seat 3, a telescopic screw 41, a movable jaw block 42, an ejection bracket 43, a clamping column 44, a support seat 45 and a fixed jaw block 46;

[0033] The universal rotation assembly 2 is arranged on the base 1, the universal rotation assembly 2 is connected to the top seat 3, and the universal rotation assembly 2 is used to rotate and adjust the angle of the top seat 3; by setting the universal rotation assembly 2, the free adjustment of the angle of the top seat 3 can be easily realized, the flexibility of the vise fixture is enhanced, and it can adapt to various complex processing requirements.

[0034] A nut seat 47 is provided at the side end of the top seat 3. The telescopic screw rod 41 is sleeved in the nut seat 47. The telescopic screw rod 41 can perform spiral telescopic movement relative to the nut seat 47. One end of the telescopic screw rod 41 is provided with a rotating handle 411. The movable clamp block 42 is arranged at the other end of the telescopic screw rod 41. The fixed clamp block 46 is arranged at the side end of the top seat 3 away from the nut seat 47. A plurality of clamping openings 460 for placing workpieces are provided on the side wall of the fixed clamp block 46 close to the movable clamp block 42. The support seat 45 is arranged between the movable clamp block 42 and the fixed clamp block 46. The clamping column 44 horizontally penetrates through the support seat 45. One end of the ejecting bracket 43 is connected to the movable clamp block 42, and the other end of the ejecting bracket 43 abuts against the clamping column 44. The clamping column 44 is used to press against the workpiece located in the clamping opening 460 along with the ejecting action of the ejecting bracket 43. When it is necessary to clamp a cylindrical workpiece, it can be placed in the clamping opening 460. Subsequently, the user can push the telescopic screw rod 41 in the direction close to the fixed clamp block 46 by rotating the rotating handle 411, so that the movable clamp block 42 can push the clamping column 44 outwards through the ejecting bracket 43 and abut against the cylindrical workpiece on the clamping opening 460, so as to press the cylindrical workpiece between the clamping column 44 and the fixed clamp block 46, thereby realizing stable clamping of the cylindrical workpiece.

[0035] As Figures 2 to 4 shown, further, a first top block 48 and a second top block 49 are further included. The ejecting bracket 43 has a U-shaped structure. The middle part of the ejecting bracket 43 is connected to the movable clamp block 42 through a first pin shaft 401. The first top block 48 and the second top block 49 are respectively connected to both ends of the ejecting bracket 43. The first top block 48 and the second top block 49 are respectively used to abut against the end part of the clamping column 44. The ejecting bracket 43 is connected to the movable clamp block 42 through the first pin shaft 401, so that the ejecting bracket 43 can swing and adjust freely within a certain range, ensuring that workpieces with different diameters can receive uniform pressure and improving the stability of clamping.

[0036] As Figure 2 and Figure 3 shown, further, the first top block 48 has a circular structure, and the first top block 48 is fixedly connected to the end part of the ejecting bracket 43.

[0040] As Figure 1 and Figure 5 shown, further, the universal rotation assembly 2 includes a spherical connecting rod 21, a pressing plate 22, and a locking screw 23. The bottom of the spherical connecting rod 21 has a spherical part 211. A hemispherical seat 10 for the spherical part 211 to move and rotate is provided on the base 1. The pressing plate 22 covers the spherical part 211. The locking screw 23 passes through the pressing plate 22 and is connected to the base 1.

The top of the spherical connecting rod 21 has a connecting rod part 212, and the connecting rod part 212 is connected to the top seat 3. The spherical part 211 at the bottom of the spherical connecting rod 21 can freely rotate in the hemispherical seat 10, thereby realizing multi-angle adjustment of the top seat 3 to adjust the angle of the fixture to adapt to machining requirements at different angles and improving the flexibility of the fixture; the locking screw 23 can adjust the pressing force of the pressing plate 22 on the spherical part 211, thereby realizing the fixation of the spherical connecting rod 21 and preventing angle deviation caused by vibration or other reasons during the machining process.

[0041] When the utility model needs to clamp a cylindrical workpiece, the workpiece can be placed in the clamping opening 460. Subsequently, the user can push the telescopic screw rod 41 towards the fixed clamping block 46 by rotating the rotating handle 411, so that the movable clamping block 42 can push the clamping column 44 outwards through the ejector bracket 43 and abut against the cylindrical workpiece on the clamping opening 460, so as to press the cylindrical workpiece between the clamping column 44 and the fixed clamping block 46, thereby realizing the stable clamping of the cylindrical workpiece; the ejector bracket 43 is connected to the movable clamping block 42 through the first pin shaft 401, so that the ejector bracket 43 can freely swing and adjust within a certain range to adapt to clamping cylindrical workpieces with different diameters and improve the clamping stability; the setting of the universal rotation assembly 2 can facilitate the free angle adjustment of the vise fixture, enhance the flexibility of the vise fixture, and enable it to adapt to various complex processing requirements.
