[0001] The utility model relates to the technical field of mold machining, in particular to a mold machining clamping device. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping.

[0003] During mold machining, the clamping device's primary function is to securely fasten the mold to the machine tool, preventing it from shifting or loosening due to vibration, cutting forces, and other factors, which could affect machining accuracy and surface quality. Therefore, the stability and reliability of the clamping device have a direct impact on mold machining quality. However, existing molds only clamp and secure the sides during machining, leaving the top unsecured. This can lead to mold wobble even after clamping. Therefore, we have proposed a new clamping device for mold machining. Utility Model Content

[0006] Furthermore, the one-way screw and the first bearing form a rotational connection, and the one-way screw and the connecting handle form a fixed connection.

[0007] Furthermore, a threaded connection is formed between the movable bearing seat and the one-way screw, and a threaded connection is formed between the clamping frame and the threaded rod.

[0008] Furthermore, the height of the fixed bearing seat and the height of the movable bearing seat are on the same horizontal line.

[0009] Furthermore, the surfaces of the movable bearing seat and the fixed bearing seat are both connected with a rotating assembly, and the rotating assembly includes a fixed block.

[0010] Furthermore, a hand-tightening bolt is inserted into the interior of the fixed block, and a first thread groove and a second thread groove are respectively formed at the upper and lower ends of the hand-tightening bolt close to the movable bearing seat.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the utility model, when the mold needs to be processed, the one-way screw can be driven to rotate by rotating the connecting handle, so that the movable bearing seat can clamp and fix both sides of the mold through the clamping frame, and then the threaded rod is rotated to clamp and fix the top of the mold, which improves the stability of the mold during clamping and avoids the problem of shaking that is prone to occur in the existing clamping method on both sides.

[0022] like Figure 1 - Figure 4 As shown, the utility model provides a mold machining clamping device, including an operating table 1, a clamping assembly 2 is connected to the surface of the operating table 1, and the clamping assembly 2 includes a fixed bearing seat 201, the fixed bearing seat 201 is connected to one side surface of the operating table 1, and a screw groove 202 is opened on the other side surface of the operating table 1. A one-way screw 211 is inserted into the screw groove 202, and the two ends of the one-way screw 211 are respectively connected to a connecting handle 204 and a first bearing 203, and the surface of the one-way screw 211 is connected to a movable bearing seat 205, and the inner sides of the fixed bearing seat 201 and the movable bearing seat 205 are both connected to a clamping frame 20 6. A threaded rod 207 is inserted into the top of the clamping frame 206, and the bottom of the threaded rod 207 is connected to the second bearing 208. The bottom of the second bearing 208 is connected to the lifting plate 209. The top of the threaded rod 207 is connected to the handle 210. The one-way screw 211 and the first bearing 203 form a rotational connection, the one-way screw 211 and the connecting handle 204 form a fixed connection, the movable bearing seat 205 and the one-way screw 211 form a threaded connection, and the clamping frame 206 and the threaded rod 207 form a threaded connection. The height of the fixed bearing seat 201 and the height of the movable bearing seat 205 are on the same horizontal line.

[0023] The effect achieved by the entire embodiment 1 is as follows: when the mold needs to be clamped and fixed, the mold can be placed between the two sets of clamping frames 206, and then the connecting handle 204 is rotated forward to drive the one-way screw 211 to rotate forward, so that the one-way screw 211 can be threadedly rotated with the movable bearing seat 205, and then the movable bearing seat 205 can push a set of clamping frames 206 to move toward the fixed bearing seat 201, and realize clamping of both sides of the mold. Then, the handle 210 is rotated again to drive the threaded rod 207 to rotate, so that the threaded rod 207 can be threadedly rotated with the clamping frame 206, and the lifting plate 209 is pushed by the second bearing 208 to clamp and fix the top of the mold. After the mold processing is completed, the handle 210 is rotated in the opposite direction, and the reverse connecting handle 204 is used to drive the movable bearing seat 205 to move outward to remove the processed mold. This avoids the problem of shaking that the existing two-side clamping method is prone to, and improves the stability of the mold after clamping.

[0026] The effect achieved by the entire embodiment 2 is: when it is necessary to process the bottom of the clamped mold, the hand-tightening bolt 302 can be rotated in the opposite direction to remove the front end of the hand-tightening bolt 302 from the second thread groove 304, and then the mold can be flipped by fixing the bearing seat 201 and the movable bearing seat 205, and then the hand-tightening bolt 302 and the first thread groove 303 can be threadedly fixed. At this time, the flipped mold can be processed, avoiding the problem that the existing device cannot flip the mold after clamping it.

[0027] Working principle: When the mold needs to be processed, the one-way screw 211 can be driven to rotate by rotating the connecting handle 204, so that the movable bearing seat 205 can clamp and fix the two sides of the mold through the clamping frame 206, and then the threaded rod 207 can be rotated to clamp and fix the top of the mold, which improves the stability of the mold during clamping and avoids the problem of shaking easily occurring in the existing clamping method on both sides. When the clamped mold needs to be flipped, the mold can be flipped directly through the fixed bearing seat 201 and the movable bearing seat 205, and then fixed by hand-tightening the bolt 302, which improves the flexibility of the mold during processing and avoids the problem that the existing device cannot flip the mold after clamping it.
