When the product 4 is hot pressed, the hot press is started, the telescopic rod 3 drives the hot pressing plates 1 to move relative to each other, the main heating plate 2 generates an extrusion force on the product 4 and heats it, and when airflow appears at the boundary of the product 4, the side of the product 4 is quickly cooled by air, resulting in a decrease in the mercury temperature of the mercury plate 503 in the mercury chamber 501 away from the side of the partition 502. Since the mercury content between the mercury plate 503 and the partition 502 is the same as the mercury content on the other side of the mercury plate 503 at the beginning, the mercury in the area on the other side of the mercury plate 503 will squeeze the mercury plate 503 to move, thereby driving the extrusion guide rod 501 to move. 04 moves, the extrusion guide rod 504 squeezes the extrusion top rod 505 on one side through the inclined protrusion set at the bottom, and the extrusion top rod 505 will drive the metal block 506 at the bottom to move. When the metal block 506 moves, the receiving rod 509 on one side will drive the receiving wheel 511 to rotate, and the receiving wheel 511 will drive the top block 510 on the side. When the top block 510 rotates, it will squeeze the transition conductive plate 507 to slide along one side of the reserved heating plate 508 and approach the metal block 506, so that the metal block 506 is fully in contact with the transition conductive plate 507 when moving, avoiding poor contact.

[0026] Since a wire is fixedly connected to the side of the metal block 506 and the other side of the wire is interconnected with a power source, the reserved heating plate 508 is energized to perform auxiliary heating on the edge of the product 4, thereby avoiding uneven heating of the product 4, thereby achieving the effect of avoiding uneven heating of the product 4 caused by wind cooling and affecting the hot pressing quality when hot pressing the plate-shaped product 4.

During vibration, a top frame is provided on the side of the deflection rod 604 away from the limit rod 601, and initially there is no extrusion force contact with the deflection rod 604. Therefore, the top of the limit rod 601 will be blocked by the blocking block 602, making it difficult for the mercury plate 503 to move during vibration. When the product 4 is heated unevenly, the force generated by the expansion of mercury will cause the limit rod 601 to squeeze the blocking block 602, and drive the bending spring 603 on the top of the blocking block 602 to bend, so that the limit rod 601 cannot restrict the movement of the extrusion guide rod 504. When the limit rod 601 is reset, the deflection rod 604 will deflect, that is, it will no longer restrict the movement of the extrusion guide rod 504, thereby achieving the effect of preventing the vibration of the hot press from affecting the hot pressing of the product 4.

[0029] Example 3: Please refer to Figure 1-4A double-heating hot press comprises a hot press plate 1, a main heating plate 2 is fixedly connected to the bottom of the hot press plate 1, a product part 4 is arranged on the side of the main heating plate 2, a telescopic rod 3 is fixedly connected to the side of the hot press plate 1 away from the main heating plate 2, an auxiliary heating mechanism 5 is arranged inside the hot press plate 1, a mercury cavity 501 is arranged inside the auxiliary heating mechanism 5, a mercury plate 503 is slidably connected to the inside of the mercury cavity 501 and located on one side of the partition 502, and the mercury content between the mercury plate 503 and the partition 502 is the same as the mercury content on the other side thereof. The mercury on both sides of the mercury plate 503 absorbs the same temperature and expands to the same extent. The side of the mercury plate 503 is fixedly connected with an extrusion guide rod 504. The bottom of the extrusion guide rod 504 is provided with an inclined protrusion, and initially contacts with the top of the extrusion push rod 505. As the extrusion guide rod 504 moves, the extrusion push rod 505 is extruded and moved downward through the inclined protrusion. The bottom of the extrusion guide rod 504 is slidably connected with the extrusion push rod 505. The bottom of the extrusion push rod 505 is fixedly connected with a metal block 506. The side of the metal block 506 A wire is fixedly connected, and the other side of the wire is connected to a power source. A transition conductive plate 507 is arranged below the metal block 506. A reserved heating plate 508 is slidably connected to the side of the transition conductive plate 507. A receiving rod 509 is fixedly connected to the bottom of the metal block 506. A receiving wheel 511 is rotatably connected to the bottom of the receiving rod 509. A top block 510 is fixedly connected to the side of the receiving wheel 511. A partition 502 is fixedly connected to the inside of the mercury cavity 501. The partition 502 is located at the center of the mercury cavity 501. A limiting mechanism 6 is arranged inside the silver cavity 501, and a limiting rod 601 is fixedly installed inside the limiting mechanism 6.

[0030] Working principle: When the product 4 is hot-pressed, the hot press is started, the telescopic rod 3 drives the hot press plates 1 to move relative to each other, the main heating plate 2 generates an extrusion force on the product 4 and heats it, and when airflow appears at the boundary of the product 4, the side of the product 4 is quickly cooled by air, resulting in a decrease in the mercury temperature of the mercury plate 503 in the mercury chamber 501 away from the side of the partition 502. Since the mercury content between the mercury plate 503 and the partition 502 is the same as the mercury content on the other side of the mercury plate 503 at the beginning, the mercury in the area on the other side of the mercury plate 503 will squeeze the mercury plate 503 to move, thereby driving the extrusion guide The rod 504 moves, and the extrusion guide rod 504 squeezes the extrusion top rod 505 on one side through the inclined protrusion set at the bottom. The extrusion top rod 505 will drive the metal block 506 at the bottom to move. When the metal block 506 moves, the receiving rod 509 on one side will drive the receiving wheel 511 to rotate, and the receiving wheel 511 will drive the top block 510 on the side. When the top block 510 rotates, it will squeeze the transition conductive plate 507 to slide along one side of the reserved heating plate 508 and approach the metal block 506, so that the metal block 506 is fully in contact with the transition conductive plate 507 when moving, avoiding poor contact.

[0031] Since a wire is fixedly connected to the side of the metal block 506 and the other side of the wire is interconnected with a power source, the reserved heating plate 508 is energized to perform auxiliary heating on the edge of the product 4, thereby avoiding uneven heating of the product 4, thereby achieving the effect of avoiding uneven heating of the product 4 caused by wind cooling and affecting the hot pressing quality when hot pressing the plate-shaped product 4.

[0032] When the hot press is started, vibration is inevitable. During vibration, a top frame is provided on the side of the deflection rod 604 away from the limit rod 601, and initially there is no extrusion force contact with the deflection rod 604. Therefore, the top of the limit rod 601 will be blocked by the blocking block 602, making it difficult for the mercury plate 503 to move during vibration. When the product 4 is heated unevenly, the force generated by the expansion of mercury will cause the limit rod 601 to squeeze the blocking block 602, and drive the bending spring 603 on the top of the blocking block 602 to bend, so that the limit rod 601 cannot restrict the movement of the extrusion guide rod 504. When the limit rod 601 is reset, the deflection rod 604 will deflect, that is, it will no longer restrict the movement of the extrusion guide rod 504, thereby achieving the effect of preventing the vibration of the hot press from affecting the hot pressing of the product 4.
