[0027] This utility model provides a simple mold fixing fixture for a CNC machine tool.

[0028] Please see Figure 1The system includes a sliding plate 1, with a second slider 10 fixedly connected to the lower surface of the sliding plate 1. The lower end of the second slider 10 is slidably connected to the interior of the second slide groove 9. The second slider 10 is fixed on the sliding plate 1. When the sliding plate 1 slides, the second slider 10 can slide inside the second slide groove 9, which can prevent the sliding plate 1 from tilting during sliding and play a guiding role. A second electric telescopic rod 6 is fixedly connected to one side of the sliding plate 1. A second fixing plate 7 is fixedly connected to the end of the second electric telescopic rod 6 away from the sliding plate 1. The second electric telescopic rod 6 is installed on the sliding plate 1. The sliding plate 1 can be pushed to slide left and right by the second electric telescopic rod 6. The second fixing plate 7 can fix the second electric telescopic rod 6, which plays a fixing role and can prevent the second electric telescopic rod 6 from tilting during extension and retraction.

[0029] Please see Figure 6 A sliding rod 11 is fixedly connected to one side of the second fixed plate 7. The outer surface of the sliding rod 11 is slidably connected to the inner wall of the second slider 10. The sliding rod 11 passes through the second slider 10 and is fixed to the second fixed plate 7. The sliding rod 11 can guide the slider 1 and prevent the slider 1 from tilting when sliding, thus playing a guiding role. When the second slider 10 moves on the sliding rod 11, it plays a guiding role. A base plate 8 is fixedly connected to the lower end of the second fixed plate 7. A second sliding groove 9 is opened on the upper surface of the base plate 8. The second fixed plate 7 is fixed on the base plate 8, which plays a fixing role. The second sliding groove 9 provided on the base plate 8 can allow the second slider 10 to slide inside the second sliding groove 9, which can guide the second slider 10 in the sliding process, thus playing a guiding role.

[0030] A fixing block 3 is fixedly connected to the upper surface of the sliding plate 1. A first sliding groove 4 is provided on the inner side of the fixing block 3. The interior of the first sliding groove 4 is slidably connected to the lower surface of the first slider 5. The fixing block 3 is fixed on the sliding plate 1. The first sliding groove 4 provided on the fixing block 3 allows the first slider 5 to slide inside it, preventing clamping of the mold. The upper surface of the sliding plate 1 is fixedly connected to the lower end of the limiting plate 209. The lower end of the first fixing plate 202 is fixedly connected to the first slider 5. The limiting plate 209 is installed on the sliding plate 1 to play a fixing role. The first fixing plate 202 is installed on the first slider 5. When the first fixing plate 202 slides, it can drive the first slider 5 to slide inside the fixing block 3.

[0031] Please see Figure 2 and Figure 3An adjustable clamping mechanism 2 is provided on the upper surface of the sliding plate 1. The adjustable clamping mechanism 2 includes a first electric telescopic rod 201 fixedly connected to the inner side of the sliding plate 1. A first fixed plate 202 is fixedly connected to the telescopic end of the first electric telescopic rod 201. A fixed column 203 is fixedly connected to one side of the first fixed plate 202. An adjusting rod 204 is hinged to one end of the fixed column 203 away from the first fixed plate 202. A connecting column 205 is hinged to one end of the adjusting rod 204. A connecting plate 206 is slidably connected to one side of the connecting column 205. A clamping column 207 is fixedly connected to one side of the connecting plate 206. When the CNC machine tool is processing, the molds being processed may be irregular in shape. If the clamping is not secure, the mold may loosen, which may cause the processed parts to be scrapped. The adjustable clamping mechanism 2 can clamp molds of different specifications.

[0032] Please see Figure 4 A limiting plate 209 is slidably connected to the outer surface of the clamping column 207. One side of the limiting plate 209 is fixedly connected to one end of the spring 208, and the other end of the spring 208 is fixedly connected to one side of the connecting plate 206. When the clamping column 207 slides, the limiting plate 209 can fix the clamping column 207 to prevent the limiting plate 209 from falling off during sliding. The spring 208 is installed on the clamping column 207 and can be adjusted according to the degree of clamping under the condition of the spring 208. The spring 208 is sleeved on the outer surface of the clamping column 207.

[0033] The first electric telescopic pole 201 and the second electric telescopic pole 6 in this application are common electrical devices in the prior art, and their models or specific structures will not be described in detail in this application.

[0034] Working principle: When a workpiece needs to be processed, it is placed inside a mold. Molds come in many sizes, and clamping different sizes can easily cause them to loosen, resulting in the workpiece being scrapped. First, the first electric telescopic rod 201 pushes the first fixed plate 202 to slide. When the clamping column 207 contacts the mold, the spring 208 adjusts the size according to the mold's dimensions, pushing the adjusting rod 204 for further adjustment, thus improving the clamping effect. The second electric telescopic rod 6 then pushes the sliding plate 1 to adjust according to the mold size. As the sliding plate 1 slides, the sliding rod 11 guides it, preventing tilting and providing guidance. When the sliding plate 1 slides, it drives the second slider 10 to slide inside the second groove 9, supporting the sliding plate 1 and preventing it from falling off. This allows for the clamping of molds of different shapes.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
