Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 7 As shown, the utility model provides a pressing and cutting die suitable for SMC insulating plates of multiple sizes, comprising a base 1, a guide rod 3 is fixedly installed on the top of the base 1, there are four groups of guide rods 3, and they are located at the four corners of the top of the base 1, a driving mechanism 2 is fixedly installed on the top of the four groups of guide rods 3, the output shaft of the driving mechanism 2 is fixedly connected to the upper die 4, and the upper die 4 and the guide rod 3 are movably sleeved;

[0028] Extension plates 5 are fixedly installed on the left and right sides of the base 1. Limiting grooves 6 are fixedly provided inside the base 1 and the extension plate 5. There are two groups of limiting grooves 6, and screw rods 7 are rotatably installed inside the two groups of limiting grooves 6. Lower molds 12 are movably installed inside the limiting grooves 6. There are two groups of lower molds 12, and the bottoms of the two groups of lower molds 12 are threadedly connected to the screw rods 7.

[0029] When it is necessary to press-cut the plate, the staff first lays the material above the lower mold 12 on the top of the base 1. When the laying is completed, the staff starts the driving mechanism 2 to make the upper mold 4 move downward along the guide rod 3 and cooperate with the lower mold 12 to press-cut the material. While pressing and cutting, the staff can pre-lay the lower mold 12 on the top of the extension plate 5. After the pressing and cutting of the upper mold 4 is completed, the staff resets the upper mold 4 and drives the cylinder 14 so that the output shaft of the cylinder 14 drives the moving block 15 to move downward. The moving block 15 drives the rear end of the fixed head 17 to retract toward the inside of the base 1 through the connecting rod 16. At this time, the moving block 15 retracts the middle part of the fixed head 17 through the connecting rod 2 18 and the connecting rod 3 19. At this time, the fixed head 17 stops fixing the front and rear sides of the lower mold 12, and then the staff starts the motor 11. The operation of the motor 11 drives the gear 9 to rotate, and the gear 9 drives the two sets of screw rods 7 through the transmission belt 10. At this time, the rotation of the screw rod 7 drives the base 1, the lower die 12 at the top of the extension plate 5 moves to the left to the top of the base 1, and the replacement is completed. Then the staff starts the cylinder 14 to fix the front and rear sides of the lower die 12 again. After the cutting and pressing is completed, some SMC materials will remain inside the upper die 4. At this time, the staff starts the motor 29. The operation of the motor 29 drives the driving block 30 to rotate. The rotation of the driving block 30 causes the moving rod 27 to slide along the inside of the moving groove 31. Due to the cross setting of the moving groove 31, the moving rod 27 will drive the moving plate 26 to move left and right along the fixing frame 25. When the driving block 30 rotates one circle, the driving block 30 will squeeze the moving rod 27, and the moving rod 27 will lift the moving rod 1 23. At this time, the spring 1 24 is compressed, and the moving rod 1 23 will lift the impact head 22. The impact head 22 will knock the upper die 4 cyclically. At this time, the material residue inside the upper die 4 will fall due to vibration.

[0030] The movement block 15 is driven upward by the operation of the cylinder 14, and at this time the fixed head 17 fixes the front and rear sides of the lower mold 12, and then the gear 9 is rotated by the operation of the motor 11, and the screw rod 7 is rotated by the transmission of the transmission belt 10, and the rotation of the screw rod 7 drives the lower mold 12 to move. Compared with the traditional device, the device drives the fixed head 17 by the cylinder 14 to fix the lower mold 12 to avoid the shaking of the lower mold 12 during pressure cutting, and then the two groups of lower molds 12 are replaced with each other through the operation of the motor 11, which can effectively utilize the pressure cutting time for pre-laying, improve work efficiency, and make the pressure cutting stable.

[0033] After the cutting and pressing is completed, some SMC material will remain inside the upper mold 4. At this time, the staff starts the motor 29. The operation of the motor 29 drives the driving block 30 to rotate. The rotation of the driving block 30 causes the moving rod 27 to slide along the inside of the moving groove 31. Due to the cross-setting of the moving groove 31, the moving rod 27 will drive the moving plate 26 to move left and right along the fixed frame 25. When the driving block 30 rotates one circle, the driving block 30 will squeeze the moving rod 27, and the moving rod 27 will lift the moving rod 1 23. At this time, the spring 1 24 is compressed, and the moving rod 1 23 will lift the impact head 22. The impact head 22 will cyclically knock on the upper mold 4. At this time, the material residue inside the upper mold 4 will fall due to vibration.

[0034] The operation of motor 29 drives the driving block 30 to rotate, and the rotation of the driving block 30 causes the moving rod 27 to slide left and right along the inside of the moving groove 31.

At this time, the spring 1 24 is compressed, and the moving rod 1 23 lifts the impact head 22. Compared with the traditional device, the device uses the operation of motor 29 to make the impact head 22 cyclically knock the upper mold 4, so that the material residue inside the upper mold 4 will fall due to the vibration, thereby avoiding impurities from remaining and ensuring the quality of sheet metal cutting.

[0038] The staff resets the upper mold 4 and drives the cylinder 14 so that the output shaft of the cylinder 14 drives the moving block 15 to move downward. The moving block 15 drives the rear end of the fixed head 17 to retract toward the inside of the base 1 through the connecting rod 1 16. At this time, the moving block 15 retracts the middle part of the fixed head 17 through the connecting rod 2 18 and the connecting rod 3 19.

[0044] The working principle and use process of this utility model:

[0045] When it is necessary to press-cut the plate, the staff first lays the material above the lower mold 12 on the top of the base 1. When the laying is completed, the staff starts the driving mechanism 2 to make the upper mold 4 move downward along the guide rod 3 and cooperate with the lower mold 12 to press-cut the material. While pressing and cutting, the staff can pre-lay the lower mold 12 on the top of the extension plate 5. After the pressing and cutting of the upper mold 4 is completed, the staff resets the upper mold 4 and drives the cylinder 14 so that the output shaft of the cylinder 14 drives the moving block 15 to move downward. The moving block 15 drives the rear end of the fixed head 17 to retract toward the inside of the base 1 through the connecting rod 16. At this time, the moving block 15 retracts the middle part of the fixed head 17 through the connecting rod 2 18 and the connecting rod 3 19. At this time, the fixed head 17 stops fixing the front and rear sides of the lower mold 12, and then the staff starts the motor 11.

At this time, the rotation of the screw rod 7 drives the base 1, the lower die 12 at the top of the extension plate 5 moves to the left to the top of the base 1, and the replacement is completed. Then the staff starts the cylinder 14 to fix the front and rear sides of the lower die 12 again. After the cutting and pressing is completed, some SMC materials will remain inside the upper die 4. At this time, the staff starts the motor 29. The operation of the motor 29 drives the driving block 30 to rotate. The rotation of the driving block 30 causes the moving rod 27 to slide along the inside of the moving groove 31. Due to the cross setting of the moving groove 31, the moving rod 27 will drive the moving plate 26 to move left and right along the fixing frame 25. When the driving block 30 rotates one circle, the driving block 30 will squeeze the moving rod 27, and the moving rod 27 will lift the moving rod 1 23. At this time, the spring 1 24 is compressed, and the moving rod 1 23 will lift the impact head 22. The impact head 22 will knock the upper die 4 cyclically. At this time, the material residue inside the upper die 4 will fall due to vibration.
