[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figures 1-9 This utility model provides a technical solution: a multi-zone independent temperature-controlled vacuum hot press furnace, including a base 1 and a top plate 2 fixedly connected to the top of the base 1 by a support rod. A double-walled water tank 3 is fixedly connected to the top of the base 1, and an insulating frame 4 is fixedly connected to the bottom of the inner cavity of the double-walled water tank 3. A hydraulic telescopic rod 5 is fixedly connected to the top of the top plate 2 through an opening. The hydraulic telescopic rod 5 is controlled by a control switch. A cover plate 6 is fixedly connected to the telescopic end of the hydraulic telescopic rod 5. An upper graphite pressure plate 7 is fixedly connected to the bottom of the cover plate 6. A support plate 9 is placed at the bottom of the inner cavity of the insulating frame 4. A graphite platform 10 is hinged to the side of the top plate 2. A lower hook plate 11 is fixedly connected to the front and rear of the support plate 9. The front and rear of the inner cavity of the insulating frame 4 are provided with mounting grooves 12 that are compatible with the lower hook plate 11. The front and rear of the bottom of the cover plate 6 are fixedly connected with an upper hook plate 13 that is compatible with the lower hook plate 11. A fixing plate 14 is fixedly connected to the front and rear of the graphite platform 10. The front and rear of the inner cavity of the insulating frame 4 are provided with fixing grooves 15 that are compatible with the fixing plate 14. The front and rear of the bottom of the top plate 2 are fixedly connected with a lower inclined panel 16 that is compatible with the fixing plate 14.

[0027] It should be noted that a guide plate is fixedly connected to one side of the insulating frame 4 to guide the slipping material into the collection box next to it for collection. The front and bottom of the double-walled water tank 3 are respectively connected to a water inlet pipe and a drain pipe. Water is added to the inner cavity of the double-walled water tank 3 through the water inlet pipe and the drain pipe to cool down the insulating frame 4 and the upper graphite pressure plate 7.

[0028] Furthermore, in order to facilitate the sealing of the through slot 17, a connecting plate 18 is fixedly connected to the front and rear of the top of the cover plate 6. A through slot 17 is opened at the front and rear of the top of the cover plate 6 between the two connecting plates 18. A sliding rod 19 is slidably connected to the front of the connecting plate 18 through an opening. One end of the sliding rod 19 is fixedly connected to an upper inclined plate 20 that is adapted to the lower inclined plate 16. A spring 21 is sleeved on the surface of the sliding rod 19 between the connecting plate 18 and the upper inclined plate 20.

[0029] Furthermore, in order to increase the stability when the lower hook plate 11 is connected to the upper hook plate 13, a stabilizing groove 22 is provided at the bottom of the lower hook plate 11, and a stabilizing rod 23 that is compatible with the stabilizing groove 22 is fixedly connected to the upper hook plate 13.

[0030] Furthermore, in order to improve the compressive strength of the graphite platform 10, a support plate 24 adapted to the graphite platform 10 is fixedly connected to one side of the bottom of the inner cavity of the insulating frame 4.

[0031] Furthermore, a vacuum pump 26 is fixedly installed on one side of the top of the base 1. The vacuum pump 26 is electrically connected to an external power source and is controlled by a control switch. The vent end of the vacuum pump 26 is connected to a vacuum tube 8. One end of the vacuum tube 8 passes through the double-walled water tank 3 and extends into the interior of the double-walled water tank 3. Several graphite heaters 25 are fixedly installed inside the upper graphite pressure plate 7 through openings. The graphite heaters 25 are electrically connected to an external power source and are controlled by a control switch.

[0032] It should be noted that an insulation plate is installed inside the upper graphite plate 7 and between the two graphite heaters 25 through an opening. The material is subjected to separate temperature control and hot pressing in multiple zones through multiple graphite heaters 25.

[0033] In use, by controlling the extension of the hydraulic telescopic rod 5, the cover plate 6 is moved downward. The cover plate 6 will move the upper graphite pressure plate 7 downward into the double-walled water tank 3 to squeeze the material in the insulating frame 4. At the same time, the vacuum tube 8 on the vacuum pump 26 is controlled to draw the double-walled water tank 3 into a vacuum state, and multiple graphite heaters 25 are controlled to start to heat the upper graphite pressure plate 7, so that the upper graphite pressure plate 7 heats the material on the graphite platform 10. At the same time, the connection of the material is observed in advance, and the power of the graphite heater 25 corresponding to the material connection is increased to enhance the heat dissipation for heat pressing, while the power of the other graphite heaters 25 is reduced.

[0034] After the material is hot-pressed, cold water is added to the inner cavity of the double-walled water tank 3 through the water inlet pipe to cool the inside of the double-walled water tank 3. Then, the hydraulic telescopic rod 5 is controlled to retract, which drives the cover plate 6 to move upward. The cover plate 6 will drive the upper graphite pressure plate 7 to move upward. The upper graphite pressure plate 7 will drive the two upper hook plates 13 to move upward. After the two upper hook plates 13 move upward a certain distance, they will contact the two lower hook plates 11. The two upper hook plates 13 will pull the two lower hook plates 11 to move upward. The two lower hook plates 11 will drive the pallet 9 to move upward. The pallet 9 will drive the material on the graphite platform 10 to move upward from the double-walled water tank 3.

[0035] When the cover plate 6 moves upward to a higher position, the two upper inclined panels 20 on the cover plate 6 will contact the two lower inclined panels 16. The inclined surfaces of the two lower inclined panels 16 will press against the inclined surfaces of the upper inclined panels 20, pushing the two upper inclined panels 20 to move forward and backward respectively. The two upper inclined panels 20 move out of the through slot 17, and the two lower inclined panels 16 will pass through the two through slots 17 and contact the fixing plate 14. The support plate 9 continuously drives the graphite platform 10 to move upward. The graphite platform 10 drives the two fixing plates 14 to press against the two lower inclined panels 16 upward. The lower inclined panels 16 will abut against the fixing plate 14, causing the graphite platform 10 to tilt to the right. The material on the graphite platform 10 will tilt and slide down and be discharged through the guide plate.

[0036] Then, control the hydraulic telescopic rod 5 to extend and drive the cover plate 6 and the upper graphite pressure plate 7 to move downward a certain distance, driving the pallet 9 and the graphite platform 10 to move downward. The graphite platform 10 will stack on the pallet 9 according to self-repositioning. Then, place the new material on the graphite platform 10, and control the hydraulic telescopic rod 5 again to drive the cover plate 6 to move downward, driving the pallet 9 and the graphite platform 10 to move downward into the insulating frame 4. The material is then hot-pressed again by the upper graphite pressure plate 7.
