A knob 510 is provided on the left side of the U-shaped frame 509. The left side of the U-shaped frame 509 is fixedly connected to the right side of the knob 510. A bidirectional screw 511 is provided on the right side of the knob 510. The right side of the knob 510 is fixedly connected to the left end of the bidirectional screw 511. Both ends of the bidirectional screw 511 are threaded with L-shaped threaded blocks 512. By rotating the knob 510, the bidirectional screw 511 can be driven to rotate. The rotation of the bidirectional screw 511 can drive the two L-shaped threaded blocks 512 to move closer to each other or further away from each other.
[0028] Two L-shaped threaded blocks 512 are each provided with a locking block 513 on one side close to each other. The L-shaped threaded blocks 512 and the locking blocks 513 are fixedly connected. The same tool mounting block 514 is slidably provided on the outer wall of the two locking blocks 513.

The top surface of the cutting table 1 is provided with a suction cup 6. The top surface of the cutting table 1 is fixedly connected with the bottom surface of the suction cup 6. By placing the lost foam on the top surface of the suction cup 6, the lost foam can be stably adsorbed on the top surface of the suction cup 6, preventing the lost foam from shifting during the cutting process.
[0029] In this embodiment, when using this device, to replace the tool mounting block 514, the knob 510 needs to be rotated. Rotating the knob 510 drives the bidirectional screw 511 to rotate, which in turn moves the two L-shaped threaded blocks 512 away from each other. This allows the locking blocks 513 to be pulled out from both sides of the tool mounting block 514, allowing the tool mounting block 514 to be removed. The desired tool mounting block 514 is then placed between the two U-shaped positioning blocks 10. Rotating the knob 510 again drives the bidirectional screw 511 to rotate, which in turn moves the two L-shaped threaded blocks 512 away from each other. The components move closer together to each other, thus installing the locking block 513 into the interior of both sides of the tool mounting block 514, making the tool mounting block 514 stable. When it is necessary to adjust the angle of the tool mounting block 514, the second motor 503 needs to be operated. The output end of the second motor 503 can drive the one-way screw 504 to rotate. The rotation of the one-way screw 504 can drive the rack 505 to move along the one-way screw 504. The movement of the rack 505 can drive the gear 508 to rotate. The rotation of the gear 508 can drive the rotating rod 507 to rotate. The rotation of the rotating rod 507 can drive the U-shaped frame 509 to rotate. The rotation of the U-shaped frame 509 can thus drive the tool mounting block 514 to adjust its angle.
