Specifically, when hot pressing is required, the lifting cylinder 12 is first started to drive the upper pressing plate 146 installed on the upper shell 144 to reach a predetermined position, and then the lifting cylinder 152 is started to drive the transmission column 154 installed on the transmission plate 153 to move downward. Since the transmission column 154 passes through the lifting plate 13 and the fixed plate 141 and is connected to the upper shell 144, the descent of the transmission column 154 will also drive the upper pressing plate 146 installed on the upper shell 144 to descend, so that the upper pressing plate 146 combines with the download plate 34 to achieve hot pressing of the product.

A baffle 93 adapted to the photoelectric switch 92 is fixedly mounted on the side of the lifting plate 13.

[0048] See also Figure 5 As shown, the height of the lifting plate 13 is limited by the cooperation of the photoelectric switch 92 and the baffle 93 to prevent the lower mold 3 and the upper mold 14 from hard collision and extrusion. Specifically, when the lifting cylinder 12 drives the upper mold 14 located on the bottom surface of the lifting plate 13 to descend toward the lower mold 3, the baffle 93 descends along with the lifting plate 13. When the lifting plate 13 drives the baffle 93 to descend to the sensing position of the photoelectric switch 92, the lifting cylinder 12 stops working, and it is determined that the upper mold 14 has reached the predetermined position.

[0049] The working process of the utility model is as follows: first, the lifting cylinder 12 is started to drive the upper mold 14 located below the lifting plate 13 to move downward in the direction of the lower mold 3. When the baffle 93 located on the lifting plate 13 moves to the sensing position of the photoelectric switch 92, the lifting cylinder 12 stops working, and the corresponding upper mold 14 stops moving downward. At this time, the upper pressing plate 146 is driven by the lower pressing component 15 to combine with the lower mold 3, thereby realizing hot pressing of the product. After the hot pressing is completed, the lower pressing component 15 drives the upper pressing plate 146 to return to the initial position, and the lifting cylinder 12 drives the lifting plate 13 to move upward and recover and also return to the initial position, waiting for the next hot pressing process.
