[0039] like Figures 1 to 15 The mold plate fixing fixture shown includes a base 2 for installing all structures. The upper surface of the base 2 is provided with a clamping plate 3 and a clamping assembly 4, which clamp the template 1 together. The length of the clamping assembly 4 is less than half of the clamping plate 3. There are several clamping assemblies 4, which are distributed on the same side of the clamping plate 3. Multiple clamping assemblies 4 can be used together to flexibly adjust the adaptation length with the template 1. The clamping assembly 4 includes a clamping block 401 and a fixed block 402. The clamping block 401 is constrained above the fixed block 402 and has a certain amount of movement. The clamping block 401 and the opposite surface of the clamping plate 3 are suitable for constraining the template 1. The fixed block 402 can be adjusted relative to the base 2 according to the width of the constrained template 1. Specifically: a plurality of equidistantly arranged slide grooves 201 are opened on the upper surface of the base 2. The slide grooves 201 pass through the side of the base 2, making it convenient for the structure cooperating therewith to be inserted from the side of the base 2. The lower surface of the fixed block 402 is provided with a limit block 9, which is suitable for being embedded in the slide groove 201 and fixed. The opposite side of the limit block 9 is provided with a guide plate 902 close to the bottom surface, and the guide plate 902 is suitable for cooperating with the slide groove 201 to form a sliding pair, which can improve the stability of the limit block 9 when it moves relative to the base 2; the upper surface of the limit block 9 is provided with a second threaded hole 901 extending downward, and the limit block 9 is suitable for being fixedly connected with the clamping plate 3 or the fixed block 402 by a bolt 10, thereby constraining the clamping plate 3 and the fixed block 402 to the base 2, and the upper surface of the clamping plate 3 is provided with a first countersunk hole 301 passing through the lower surface, and the fixed block 402 is provided with a third countersunk hole 407 passing through the lower surface on the inner bottom surface of the upper surface slide groove 201. The bolt 10 passes through the first countersunk hole 301 or the third countersunk hole 407 and is threadedly connected to the limit block 9, and the clamping plate 3 and the fixed block 402 are tightened and fixed to the base 2.

[0040] The inner bottom surface of each chute 201 is provided with a slag discharge groove 202 that passes through the lower surface of the base 2, which is suitable for discharging waste slag that falls into the chute 201 during the processing of the template 1, so as to prevent the waste slag generated during the processing of the template 1 from interfering with the sliding pair or scratching the contact surface of the sliding pair.

[0041] A recess is provided on the upper surface of the fixing block 402, and a movable gap 404 is reserved between the clamping block 401 and the inner bottom surface of the recess of the fixing block 402. The lower edge of the clamping block 401 away from the template 1 is an arc-shaped flange 403, which is suitable for close contact with the arc transition surface between the bottom surface of the recess and the side wall. A second recess 405 is provided on the upper surface of the clamping block 401, which passes through the lower surface. The fixing block 402 is provided with a first threaded hole 406 extending downward on the inner bottom surface of the upper surface recess. The clamping block 401 is constrained on the fixing block 402 by a bolt 10 passing through the second recess 405. The clamping block 401 can swing on the flange 403 as a fulcrum, so that the template 1 has no resistance when being put in and no resistance when being taken out, and the tightening in the length direction can be maintained without the need for an additional motion structure.

[0042] The two ends of the clamping plate 3 are provided with baffles to prevent the clamped template 1 from moving. The baffles provided at both ends of the clamping plate 3 are respectively a movable baffle 5 and a fixed baffle 6. The fixed baffle 6 is fixedly connected to the end of the clamping plate 3 by bolts 10 and remains fixed. The movable baffle 5 is driven by the driver 8 to move along the length direction of the clamping plate 3 to achieve clamping or releasing action. The main part of the driver 8 is a telescopic rod 801. The cylinder body of the telescopic rod 801 is fixedly connected to the clamping plate 3 through the connecting frame 802 to maintain the stability of the telescopic rod 801. The telescopic rod 801 adopts a hydraulic cylinder to provide sufficient clamping force. The movable baffle 5 is provided with a fitting groove 501 on the side opposite to the clamping plate 3, which is suitable for fitting with the outer side surface of the clamping plate 3 to form a sliding pair, so that the movable baffle 5 has better stability. The base 2 is fixedly connected to the bottom plate 7 at the four corners near the lower surface. A number of connecting hole 701 is provided on the bottom plate 7, and the entire clamp can be fixed to the frame or workbench by connecting parts such as bolts 10.

[0043] Working principle: When in use, first fix the clamping plate 3 on the base 2, then adjust a fixed block 402 to make it close to the clamping plate 3, place the template 1 to be processed between the clamping assembly 4 and the clamping plate 3, and let the edge of the fixed block 402 support the template 1. The first fixed block 402 can be fixed to the base 2 with bolts 10, and then other fixed blocks 402 are fixed along the edge of the template 1 until the total length of all fixed blocks 402 is just greater than the length of the clamping plate 3. Finally, the clamping block 401 is constrained to each fixed block 402 with bolts 10. Since the clamping block 401 has a certain movable gap 404, it can be easily taken and placed between the clamping plate 3 and the clamping block 401 during use. Of course, the mold plate needs to be fixed during the processing process, which is completed by the fixed baffle 6 and the movable baffle 5. The debris generated during processing is discharged through the slag discharge chute 202 at the bottom of the chute 201. The movable baffle 5 is controlled by the hydraulic system and will be released after the template 1 is processed, making the operation more straightforward.
