[0027] Specifically, Figure 1 , Figure 6 and Figure 7As shown, the auxiliary pressure mechanism 7 includes a cylinder 701 installed on the left side of the upper end of the first-level cooling chamber 4, a lifting slide bar 702 movably installed on the left side of the upper end of the first-level cooling chamber 4 and located below the cylinder 701, a second helical extrusion spring 706 installed between the telescopic end of the cylinder 701 and the upper end of the lifting slide bar 702, a four-claw pressure frame 703 installed at the lower end of the lifting slide bar 702, a universal pressure plate 704 installed on four brackets of the four-claw pressure frame 703 through a universal joint, and a second water-cooling module 705 installed at the lower end of the cylinder 701 and used for cyclic cooling treatment of the lifting slide bar 702, wherein the provision of the second helical extrusion spring 706 can prevent the four-claw pressure frame 703 and the universal pressure plate 704 from directly and rigidly contacting the hot pressing mold 15 or the hot pressing die head 16, which can make the entire auxiliary pressure process more stable and controllable, thereby further reducing the occurrence of abnormal problems such as deformation and cracking during the cooling process of the microcrystalline glass.

[0029] Specifically, Figure 1 , Figure 6 and Figure 8 As shown, a circulating water pipe 901 is wound around the outside of the heat-resistant insulation layer 12 in the secondary cooling chamber 5, and a water circulation pipeline 9 for circulating cooling water into the circulating water pipe 901, the first water cooling module 605 and the second water cooling module 705 is installed at the lower end of the secondary cooling chamber 5. The cooling water can be circulated through the water circulation pipeline 9 to the circulating water pipe 901, the first water cooling module 605 and the second water cooling module 705, thereby realizing water cooling treatment of key parts of the hot pressing mechanism 6, the auxiliary pressure mechanism 7 and the secondary cooling chamber 5, thereby ensuring stable operation of the equipment.

[0030] Specifically, Figure 4 and Figure 5As shown, the rear ends of the three-stage heating chamber 3 and the first-stage cooling chamber 4 are provided with an external positioning part for detecting the position of the hot pressing die head 16 on the hot pressing mold 15 inside the heat-resistant insulation layer 12, and the external positioning part includes a positioning guide rod 19 movably installed at the rear ends of the three-stage heating chamber 3 and the first-stage cooling chamber 4 with the front end facing the hot pressing die head 16, and a micro switch 20 installed at the rear ends of the three-stage heating chamber 3 and the first-stage cooling chamber 4 and abutting against the rear end of the positioning guide rod 19. Since the temperature inside the three-stage heating chamber 3 is the highest, the combination of the built-in positioning guide rod 19 and the external micro switch 20 can ensure the position detection of the hot pressing mold 15 and the hot pressing die head 16 without easily causing problems such as thermal damage and aging of the electronic part of the micro switch 20, thereby improving the stability and safety of the hot pressing molding device in detecting materials and the hot pressing molding work.

[0031] Working principle: When in use, the microcrystalline glass to be hot-pressed can be placed in the hot-pressing mold 15, and then the hot-pressing die head 16 can be placed in the reserved hole of the hot-pressing mold 15, and then the hot-pressing mold 15 can be placed on the slide 14, and then grabbed and pushed into the push plate guide rail 13 by the manipulator. The hot-pressing mold 15 after being placed will move horizontally to the right at a uniform speed in the heat-resistant insulation layer 12 between the middle parts of the first-level heating chamber 1, the second-level heating chamber 2, the third-level heating chamber 3, the first-level cooling chamber 4 and the second-level cooling chamber 5. The far-infrared heating tubes 17 and the corundum heating rods 18 distributed up and down in the first-level heating chamber 1, the second-level heating chamber 2 and the third-level heating chamber 3 can heat the hot-pressing mold 15 synchronously from top to bottom, and the microcrystalline glass in the hot-pressing mold 15 can be heated in the first-level heating chamber 1, The temperature between the secondary heating chamber 2 and the tertiary heating chamber 3 is evenly increased and heated. When the microcrystalline glass to be processed enters the tertiary heating chamber 3, the hot pressing die head 16 on the hot pressing mold 15 will contact and squeeze the positioning guide rod 19, and the positioning guide rod 19 can move backward to squeeze the micro switch 20. At this time, the hot pressing mechanism 6 can work, and the telescopic end of the servo electric cylinder 601 can move downward. The spring pressure frame 604 under the outer slide cylinder 603 will pre-contact the upper end surface of the hot pressing mold 15 on the slide plate 14, and assist in pressing down and fixing the hot pressing mold 15. At the same time, the microcrystalline glass in the hot mold can be subjected to the first step of hot pressing treatment, and then the servo electric cylinder 601 will continue to drive the middle pressure block 602 to contact and squeeze the hot pressing die head 16 downward. The hot pressing die head 16 will The glass is squeezed to form a reserved window. When the pressure sensor 607 detects that the downward pressure reaches the set value, the servo electric cylinder 601 can be reset to the initial position upward, thus completing the hot pressing forming operation of the microcrystalline glass. The microcrystalline glass after hot pressing can continue to enter the primary cooling chamber 4 and the secondary cooling chamber 5. When the blower 8 is working, air can be supplied to the primary cooling chamber 4 and the secondary cooling chamber 5 respectively through the first air inlet duct 801 and the second air inlet duct 802, and the air blowing cooling treatment entering the primary cooling chamber 4 and the secondary cooling chamber 5 is carried out. When the hot pressing die head 16 on the hot pressing mold 15 contacts and squeezes the positioning guide rod 19, the positioning guide rod 19 can move backward to squeeze the micro switch 20. At this time, the auxiliary pressure mechanism 7 on the primary cooling chamber 4 can work, and the air The cylinder 701 can drive the lifting slide bar 702 to move, and the four-claw pressure frame 703 on the lifting slide bar 702 can move downward. When the universal pressure plate 704 on the four-claw pressure frame 703 contacts and squeezes the hot pressing mold 15, it can prevent the microcrystalline glass after hot pressing from being deformed or cracked due to the cold in the hot pressing mold 15, thereby ensuring the yield rate and finished product quality of the microcrystalline glass after hot pressing. The microcrystalline glass after air cooling in the first cooling chamber 4 will continue to enter the second cooling chamber 5, and the circulating coolant can circulate through the water circulation pipeline 9 into the circulating water pipe 901 to perform water cooling on the heat-resistant insulation layer 12 in the second cooling chamber 5. At the same time, the blower 8 can perform air cooling on the second cooling chamber 5 through the second air inlet duct 802.After the water cooling and air cooling treatment, the glass-ceramics can slide out of the hot pressing molding device in the push plate guide rail 13, thus completing a series of continuous heating, constant temperature and constant pressure hot pressing and stage cooling operations of the glass-ceramics.
