[0029] Specifically, such as Figures 1-4 As shown, after the workpiece is placed on top of the lower heating platform 23, an outer frame 10 is installed on the outer side of the top of the lower heating platform 23. The heating tube 11 fixed inside the outer frame 10 can heat the outer side of the workpiece. Together with the upper heating platform 9 at the top and the lower heating platform 23 at the bottom, the outer side of the workpiece can be heated evenly. After heating, when hot pressing, the hydraulic cylinder 8 is controlled to start the drive of the movable seat 5 to move down. During the hot pressing process, the outer frame 10 can be pushed down at the same time. The floating structure will not affect the hot pressing process of the machine.

[0030] A lead screw 21 is movably connected at the middle position inside the inner cavity 13, and a threaded sleeve 15 is threadedly connected to the outside of the lead screw 21. The top end of the threaded sleeve 15 is fixedly connected to the rear end of the bottom of the mounting platform 14. A servo motor 22 is fixedly installed at the rear end of the operating platform 3. Slider blocks 12 are fixedly fixed on both sides of the bottom end of the inner cavity 13. Slide grooves 16 are opened in the interior of both sides of the bottom end of the mounting platform 14, and the two ends of the slide grooves 16 pass through the interior of both ends of the mounting platform 14. The output shaft of the servo motor 22 is fixedly connected to the rear end of the lead screw 21. The slide grooves 16 are slidably connected to the outside of the sliders 12.

[0031] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, the servo motor 22 can be controlled to start and drive the lead screw 21 to rotate. When the lead screw 21 rotates, the threaded sleeve 15 connected by the thread can drive the mounting table 14 to move forward. After the mounting table 14 is moved forward to the outside of the device and away from the bottom hot pressing area of ​​the upper heating table 9, the workpiece can be conveniently and safely picked up and placed on the lower heating table 23.

[0032] An outer cover 4 is provided on the outside of the top seat 6. Screws 26 are fixed on both sides of the bottom of both ends of the top seat 6, and locking rings 25 are threaded on the outside of the screws 26. Reservation slots 24 are vertically opened on both sides of both ends of the outer cover 4. The reservation slots 24 penetrate through the interior of both ends of the outer cover 4, and the screws 26 penetrate through the interior of the reservation slots 24.

[0033] Specifically, such as Figure 1 and Figure 5 As shown, when the hot press is stopped, the locking rings 25 can be loosened from the outside of the screws 26 at both ends of the outer cover 4 to unlock the position of the outer cover 4. Then the acrylic outer cover 4 can be lowered and cover the hot pressing processing area to protect the inside of the hot press from dust.

[0034] The bottom of the top seat 6 is provided with a movable seat 5. Guide rods 7 are vertically fixed on both sides of the bottom of the top seat 6.

Support legs are fixed at the four corners of the bottom of the machine base 2.

[0035] Working Principle: In use, the servo motor 22 drives the lead screw 21 to rotate. Simultaneously, the threaded sleeve 15 drives the mounting platform 14 forward, moving it to the outside of the device and away from the bottom hot-pressing area of ​​the upper heating platform 9. This allows for convenient and safe handling of the workpiece on the lower heating platform 23. After placing the workpiece on top of the lower heating platform 23, an outer frame 10 is installed on the outer side of the top of the lower heating platform 23. Heating tubes 11 fixed inside the outer frame 10 heat the outer side of the workpiece. Combined with the upper heating platform 9 and the lower heating platform 23, the outer side of the workpiece is uniformly heated. During hot pressing, the hydraulic cylinder 8 drives the movable seat 5 downwards. Simultaneously, the outer frame 10 is pushed downwards. This floating structure ensures that the hot pressing process is not affected.

[0036] When the hot press is stopped, the locking rings 25 can be loosened from the outside of the screws 26 at both ends of the outer cover 4 to unlock the position of the outer cover 4. Then the outer cover 4 can be lowered and cover the hot pressing processing area to protect the inside of the hot press from dust.
