When the first insulation board 22 stops sliding, the top plate 33 will push the first insulation board 22 to the bottom of the slide rail 2. The pressure applied by the insulation board 22 is transmitted to the spring 32, so that the spring 32 is in a compressed state, and then the spring 32 releases its elastic potential energy and applies elastic force to the top plate 33 to drive the top plate 33 to squeeze the first insulation board 22; through the cooperation of the spring 32 and the top plate 33, the top plate 33 will squeeze the surface of the first insulation board 22 under the elastic force of the spring 32, so that the uneven area on the surface of the first insulation board 22 fits the middle part of the mold 108, thereby increasing the contact area between the first insulation board 22 and the mold 108, and enhancing the insulation effect of the first insulation board 22 on the mold 108.

[0032] Working principle: After the staff opens the cover 109, the starter drives the motor 103 and the air pump 110 to start. After the motor 103 is started, the threaded rod 104 will rotate. When the threaded rod 104 rotates, the slider 105 will move along the threaded rod 104. When the slider 105 moves, it will drive the spray gun 106 to move together and approach the mold 108. When it reaches the appropriate distance, the spray gun 106 will spray the foaming material into the mold 108. After the end, the staff can cover the cover 109 to make the mold 108 in a closed state and shape the foaming material. After the air pump 110 is started, air will be sent into the pipeline. The airflow will pass through the pipeline into the heating component 111 and be heated by the heating component 111. Then the heated air will pass through the The exhaust gas will enter the interior of the box 107 through the air inlet pipe 112, and the air inside the box 107 will conduct heat conduction with the mold 108, so that the ambient temperature inside the mold 108 always maintains a suitable foaming temperature, and the airflow in the box 107 will enter the exhaust pipe 113 after completing the heating work on the mold 108, and finally the exhaust gas will be ejected from the exhaust pipe 113 and reach the surface of the air pump 110, so that the exhaust gas takes away the heat on the surface of the air pump 110, and the device cools the air pump 110; before the device is started, the first insulation board 22 is inside the slide rail 2 and contacts with the mold 108. Because the thermal conductivity of the first insulation board 22 is low, it will reduce the internal heat loss of the mold 108 when it is working, and the airflow in the box 107 will pass through the mold The bottom of the mold 108 is contacted to heat the mold 108. At the same time, when the first insulation board 22 needs to be replaced, the staff can hold the handle 23 to pull the first insulation board 22 out from between the adjacent slide rails 2 to achieve quick disassembly of the first insulation board 22; when the first insulation board 22 slides along the slide rail 2, it will contact and squeeze the top plate 33, and the first insulation board 22 will also contact the ball bearings 34 and make the ball bearings 34 roll under the action of friction, reducing the friction force on the first insulation board 22 when it moves. When the first insulation board 22 stops sliding, the top plate 33 will transfer the pressure applied by the first insulation board 22 to the spring 32, so that the spring 32 is in a compressed state, and then the spring 32 will release its elastic potential energy And an elastic force is applied to the top plate 33 to drive the top plate 33 to squeeze the first insulation plate 22; when the first insulation plate 22 slides along the slide rail 2, the first insulation plate 22 will come into contact with the brush 42, and when the brush 42 comes into contact with the first insulation plate 22, the surface of the first insulation plate 22 will be cleaned, thereby reducing impurities on the surface of the first insulation plate 22, improving the cleanliness and smoothness of the surface of the first insulation plate 22, and reducing the friction of the first insulation plate 22 when moving; when the airflow flows in the box 107, it will reach the bottom of the mold 108, and then the airflow will come into contact with the spoiler 5 and flow along the surface of the spoiler 5. Because the spoiler 5 is a wavy structure, the flow distance of the airflow is increased, thereby increasing the contact time of the airflow mold 108;When the airflow enters the box 107, it will diffuse. The diffused airflow will pass through the baffle 6 and flow along the surface of the baffle 6, so that the airflow will stay away from the edge of the inner wall of the box 107, optimizing the distribution range of the airflow in the box 107; the heated airflow will enter the box 107 through the air inlet pipe 112, and the second insulation board 7 has a low thermal conductivity, which reduces the heat loss during the airflow.
