[0040] In detail, one end of the top of the refrigeration cylinder 34 is fixedly connected to a liquid adding pipe, and a liquid adding plug is provided at the top of the liquid adding pipe, and observation windows are provided on both sides of the refrigeration cylinder 34, and a transparent observation plate is fixedly connected to the inside of the observation window;

[0041] Preferably, a stop ball is fixedly connected to one end of the stop shaft 41 close to the locking disk 44, a stop groove is provided on the outer side of the locking disk 44, and the cross-sectional shape of the stop groove is arc-shaped, and the stop ball is snap-connected to the inside of the stop groove.

[0042] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0043] Working principle: connect the external air pump to the air delivery pipe and the exhaust pipe, then place the mold to be cooled on the carrier plate 12 at the bottom of the support frame 2, then start the transmission motor 7 to drive the transmission polished rod 3 to rotate, and cooperate with the setting of the thread segments 4 with opposite thread rotation directions at two places, so that the two thread segments 4 can drive the two support plates 5 to approach each other until the other carrier plate 12 reaches the top of the upper mold;

[0044] At the same time, the external air pump is started to guide the gas inside the carrying cylinder 10 to the inside of the transmission pipe 23 through the transmission hose 24, so as to suck the displacement sheet 18 to slide inside the carrying cylinder 10, so as to make the transmission disk 20 close to the carrying cylinder 10, and cooperate with the setting of the transmission seat 21. When the transmission disk 20 moves upward, it can pull the guide plate 15, so as to make the positioning frame 14 close to the mold under the support of the guide shaft 13, and finally complete the positioning of the upper mold and the lower mold through the positioning frames 14 on the two carrying plates 12;

[0045] The transmission motor 7 is restarted to drive the transmission light rod 3 to rotate, causing the two support plates 5 to move away from each other, thereby exposing the cavities of the upper and lower molds, and then the limit plate 42 is pulled to move the anti-rotation shaft 41 out of the locking plate 44, thereby unlocking the extension frame 37, and then pushing the cavity heat dissipation tube 38, so that the cavity heat dissipation tube 38, supported by the extension frame 37, reaches between the upper and lower molds, and at the same time releases the limit plate 42. Since the anti-rotation spring 43 is located between the anti-rotation shaft 41 and the limit plate 42, when the limit plate 42 is pulled, the anti-rotation spring 43 can be stretched, and then when the limit plate 42 is released, the anti-rotation shaft 41 can be pushed by the anti-rotation spring 43 to be re-stuck into the locking plate 44, thereby locking the position of the extension frame 37;

[0046] Add cooling liquid to the liquid filling cavity, and start the semiconductor refrigeration sheet 36. The cooling temperature of the semiconductor refrigeration sheet 36 when in operation can be transferred to the cooling liquid in the liquid filling cavity by means of the temperature conducting frame 35 to cool it down. Then start the fan 33 to inject the external airflow into the side heat dissipation pipe 30 through the air supply pipe 31. When the airflow passes through the refrigeration cylinder 34, the temperature of the airflow can be reduced by the low-temperature liquid. A part of the airflow entering the side heat dissipation pipe 30 will be transferred to the cavity heat dissipation pipe 38 through the air delivery hose 39, so as to spray the airflow to the cavity of the mold through the cavity heat dissipation pipe 38, and the rest of the airflow will be sprayed to the sides of the upper mold and the lower mold through the side heat dissipation pipe 30.

[0047] The driving motor 29 can be started to drive the driving shaft 25 to rotate, and the connection between the driving shaft 25 and the linkage shaft 26 can make the linkage shaft 26 rotate along with the driving shaft 25. Through the setting of the synchronous belt 28, the power of the linkage shaft 26 can be transmitted to the carrying tube 10, prompting the carrying tube 10 to drive the carrying plate 12 to rotate, thereby adjusting the contact surface between the upper mold and the lower mold and the side heat dissipation tube 30, and reducing the operating blind area of ​​the side heat dissipation tube 30.
