[0025] The workbench 1 is composed of a horizontal plate and four rotating seats. The top of the horizontal plate of the workbench 1 is fixedly connected to the four rotating seats. The four corners of the lower mold 3 are in contact with the limit plates 2. The upper mold 6 and the lower mold 3 can be aligned through the limit plates 2. The lower mold 3 is composed of a first pressing plate and a first mold. The middle position of the top of the first pressing plate of the lower mold 3 is fixedly connected to the first mold. The upper mold 6 is composed of a second pressing plate and a second mold. The middle position of the bottom of the second pressing plate of the upper mold 6 is fixedly connected to the second mold. Sliding slot holes are provided on both the left and right sides of the second pressing plate of the upper mold 6. The upper mold 6 is located directly above the lower mold 3. Molding can be carried out through the upper mold 6 and the lower mold 3. The support frame 4 is composed of a horizontal frame and four vertical shafts. The four corners of the horizontal frame of the support frame 4 are fixedly connected to the vertical shafts. The relative inner sides of the four vertical shafts of the support frame 4 are in contact with the limit plates 2. The hydraulic rods 5 can be fixed through the support frame 4. Threaded protrusions are provided on the outer sides of the adjusting rods 9. Threaded slot holes are provided on the inner sides of the adjusting blocks 10. The mounting shafts 11 are all in an "L" shape structure. Rectangular limit slots are provided on the mounting shafts 11. The sum of the thicknesses of the demolding plates 12 and the limit blocks 13 is equal to the inner depth of the mounting shafts 11. The compression springs 14 and the limit blocks 13 are alternately distributed from front to back. The demolding plates 12 can be lifted by the compression springs 14, and the front-to-back movement or left-to-right movement of the demolding plates 12 can be prevented through the limit blocks 13.

[0026] Workflow: Before use, fix the device in a suitable position and turn on the power. The hydraulic rod 5 and the small motor 8 of this device are both electrical instruments. This device is equipped with an external controller. Manually operating the external controller can adjust the operating states of the hydraulic rod 5 and the small motor 8. The external controller can make the four hydraulic rods 5 operate synchronously, and the external controller can make the two small motors 8 operate synchronously. All of the above are existing technologies. When the device is not in use, the hydraulic rod 5 fixedly connected to the support frame 4 is in a retracted state. The upper mold 6 is located directly above the lower mold 3 fixedly connected to the workbench 1, and the upper mold 6 does not contact the lower mold 3. The adjusting block 10 is located in the front half of the adjusting rod 9, and the compression spring 14 is in a natural state. The compression spring 14 pushes the demolding plate 12 upward, so that the demolding plate 12 is located above the mounting shaft 11, and the limiting block 13 is used to prevent the demolding plate 12 from moving left and right or forward and backward. When using this device, the staff first clamp the four corners of the sound insulation cotton with the cotton block clamp 15. The sound insulation cotton is slightly larger than the first mold of the lower mold 3. Then manually operate the external controller to make the two small motors 8 rotate synchronously in the reverse direction. The two adjusting rods 9 can be rotated synchronously by the small motors 8. Since the thread directions of the two adjusting rods 9 are opposite, and there is a fixed connection between the mounting shafts 11 fixedly connected to the relative inner sides of the two adjusting blocks 10, the adjusting rod 9 can drive the two adjusting blocks 10 to move forward or backward together, so that the adjusting block 10 drives the mounting shaft 11 to move backward, and then the cotton block clamp 15 can drive the sound insulation cotton to move backward synchronously. Since the compression spring 14 pushes the demolding plate 12 upward and the sound insulation cotton is slightly higher than the lower mold 3, the sound insulation cotton will not be blocked by the lower mold 3 and can move backward stably. After the small motor 8 rotates a fixed number of turns, the external controller controls the small motor 8 to stop automatically. At this time, the sound insulation cotton is located directly above the lower mold 3 and completely covers the lower mold 3. At this time, make the four hydraulic rods 5 extend synchronously through the external controller, and then the upper mold 6 can move downward. The upper mold 6 is limited by the limiting shaft 7 to prevent the upper mold 6 from displacing in the front-back direction or left-right direction. If there are still minor errors, the accurate engagement of the upper mold 6 and the lower mold 3 can be ensured through the guidance of the limiting plate 2, and then the sound insulation cotton can be molded. When the upper mold 6 moves downward to a certain height, the bottom of the upper mold 6 will press the transmission block 16 downward, and then the cotton block clamp 15 and the demolding plate 12 will move downward, compressing the compression spring 14. When the upper mold 6 and the lower mold 3 are in accurate contact and molding, the bottom of the limiting block 13 contacts the mounting shaft 11, and the cotton block clamp 15 will no longer move downward. At this time, the bottom of the sound insulation cotton contacts the top of the lower mold 3, which can ensure that the cotton block clamp 15 will not tear the sound insulation cotton during the molding process. After the molding is completed, the upper mold 6 returns to its original position, and then the compression spring 14 can push the demolding plate 12 upward again to automatically demold the sound insulation cotton. Subsequently, the staff makes the two small motors 8 reverse through the external controller to move the adjusting block 10 forward, and then the sound insulation cotton can be driven forward;The device can clamp the sound insulation cotton through the cotton block clamp 15, drive the adjusting rod 9 to rotate through the small motor 8, move the adjusting block 10 back and forth for feeding and taking materials, and can ensure accurate feeding position. Through the cooperation of the compression spring 14 and the transmission block 16, the sound insulation cotton automatically moves down during molding and automatically demolds after molding. This feeding method is time-saving and labor-saving, and more accurate.
