[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] Embodiment 1: A high-temperature and high-pressure adjustable molding device for molding tray processing, comprising an operating table 1 and a lower mold seat 3, wherein the lower mold seat 3 is fixedly mounted on the upper surface of the operating table 1, a support column 2 is fixedly mounted on the bottom surface of the operating table 1, a support base 201 is fixedly mounted on the bottom surface of the support column 2, and the support columns 2 are symmetrically distributed at the four corners of the bottom surface of the operating table 1, a pressurizing mechanism is arranged on the upper surface of the operating table 1, and a heating mechanism is arranged on the side surface of the lower mold seat 3;

[0025] The pressurizing mechanism includes a pressing unit and a limiting unit. The pressing unit includes a support plate 306, a fixed plate 307, a hydraulic cylinder 308, a lifting column 309, a connecting piece 310, an upper mold seat 311 and a molding block 312. The support plate 306 is fixedly installed on the upper surface of the operating table 1, the fixed plate 307 is fixedly installed on the upper surface of the support plate 306, the hydraulic cylinder 308 is fixedly installed on the top surface of the fixed plate 307, the lifting column 309 is installed on the output end of the hydraulic cylinder 308, the connecting piece 310 is fixedly installed on the bottom surface of the lifting column 309, the upper mold seat 311 is installed on the bottom surface of the connecting piece 310, and the molding block 312 is fixedly installed on the upper surface of the operating table 1. 12 is fixedly installed in the middle position of the bottom surface of the upper mold base 311, and holes are pierced through the upper surface of the fixed plate 307 at equal intervals. The upper end of the lifting column 309 passes through the hole and is connected to the output end of the hydraulic cylinder 308. The hydraulic cylinder 308 is fixedly installed on the upper surface of the fixed plate 307 at equal intervals. The lifting column 309 is fixedly connected to the upper surface of the upper mold base 311 through the connecting piece 310. By setting a pressurizing mechanism for pressing, the number of connections between the lifting column 309 and the upper mold base 311 can be adjusted according to production needs. The pressure of the pressurized pressure can be used to mold the tray, making the processing smoother.

[0026] The limiting unit includes a mounting hole 303, a limiting column 304 and a limiting plate 305. The mounting hole 303 is opened at the four corners of the upper surface of the lower mold base 3. The limiting column 304 is fixedly installed on the inner bottom surface of the mounting hole 303. The limiting plate 305 is fixedly installed on the upper surface of the limiting column 304. A card slot 302 is opened on the upper surface of the lower mold base 3. The card slots 302 are symmetrically distributed on both sides of the upper surface of the lower mold base 3. A card block 313 is fixedly installed on the side of the mold block 312. The card block 313 is symmetrically distributed on the four sides of the mold block 312. The length and width of the card block 313 are the same as the length and width of the card slot 302.

[0027] When processing the molded pallet, the number of connected hydraulic cylinders 308 is adjusted according to the required pressure to perform the molding operation. When the pressure is reduced, the bolts in the connecting piece 310 are removed to separate the upper mold seat 311 from the lifting column 309. Conversely, when the pressure needs to be increased, the lifting column 309 and the upper mold seat 311 are connected through the connecting piece 310. The hydraulic cylinder 308 works to push the lifting column 309 to descend, driving the upper mold seat 311 and the molding block 312 to descend so that the molding block 312 is pressed against the molding groove 301. At the same time, the upper mold seat 311 moves and limits on the outer surface of the limiting column 304.

The outer surface of the lifting plate 322 contacts the inner wall of the circular hole 318. By setting a heating mechanism, the temperature can be increased or not increased as needed, thereby improving the processing effect. After the molding of the tray is completed, the lifting plate 322 can rise to push the tray out of the molding groove 301 for easy removal of the material.

[0030] When the tray is molded, the steam generator 317 works to generate steam, which is then input into the molding groove 301 through the steam pipe 315 for heating. After the tray molding is completed, the cylinder 320 works to push the telescopic column 321 to rise, driving the lifting plate 322 to rise. The lifting plate 322 leaves the circular hole 318 to eject the tray from the bottom surface of the molding groove 301 and then take it out to complete the discharge.
