[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 - 5, the present utility model provides the following technical solutions: a press for producing automotive lighting optical glass lenses, including a hot press machine 1, an installation frame 2 is installed above the rear of the hot press machine 1, a hydraulic rod 3 is installed above the left of the installation frame 2, a limiting rod 9 penetrates through the upper right of the installation frame 2, the output end of the hydraulic rod 3 and the lower end of the limiting rod 9 are both connected to an installation plate 4, and a hot press head 5 is installed on the lower side of the installation plate 4; a moving rod 13 penetrates through the rear end of the installation plate 4, a protective cover 14 is installed at the lower end of the moving rod 13, and the upper rear end of the protective cover 14 is connected to the installation plate 4 through a compression spring 12; a card slot 11 is opened on the upper side surface of the hot press machine 1, and a lower mold 10 is installed on the hot press machine 1;

[0025] Further, the limiting rod 9 is slidably connected to the installation frame 2, and the limiting rod 9 is of a "T" - shaped structure; the position of the card slot 11 and the position of the protective cover 14 are arranged corresponding to each other, and the protective cover 14 is of an annular structure; the protective cover 14 and the installation plate 4 form an elastic structure through the compression spring 12, and the moving rod 13 on the protective cover 14 is slidably connected to the installation plate 4;

[0026] Place the lens on the lower mold 10 at the left position, open the hydraulic rod 3, push the installation plate 4 to drive the hot press head 5 to move downward. At this time, the protective cover 14 outside the hot press head 5 moves downward synchronously, and the protective cover 14 gradually snaps into the card slot 11. The hot press head 5 continues to move downward. At this time, the protective cover 14 squeezes and stores energy in the compression spring 12. At the same time, the moving rod 13 installed on the upper side of the protective cover 14 slides synchronously in the installation plate 4, so that the protective cover 14 continuously shields and protects the hot - pressing area, avoiding accidental touch and burning phenomena. When the hot press head 5 gradually approaches the lower mold 10, the hot press head 5 heats and presses the lens. By heating and applying pressure, the lens is heated to a high - temperature state above its glass transition temperature, its material flows, gradually deforms, and finally forms a curved surface shape. After processing and forming, the hydraulic rod 3 can be controlled to drive the installation plate 4 to move upward, thereby controlling the hot press head 5 to move upward for demolding. The protective cover 14 is synchronously forced to move upward, and through the elastic force of the compression spring 12, the protective cover 14 is reset, leaving a space to take out the processed and formed lens;

[0027] Furthermore, a rack 6 is connected to the outer side of the rear end of the installation plate 4, a gear 8 is meshed with the outer side of the rack 6, a rotating shaft 7 is key - connected to the inner side of the gear 8, and the rotating shaft 7 is rotatably connected to the installation frame 2;

[0028] Specifically, the rack 6 is meshed with both the left and right sides of the gear 8, and the two racks 6 are distributed in parallel;

[0029] When the mounting plate 4 at the left position moves downward, it can control the downward movement of the outer mounting side rack 6. The rack 6 controls the counterclockwise rotation of the gear 8 engaged on the outside, thereby controlling the upward movement of the rack 6 engaged on the right side. The rack 6 can then control the mounting plate 4 at the right position to drive the hot press head 5 upward and move the protective cover 14 upward. Therefore, when hot pressing and forming is performed at the press station at the left position, the press station at the right position is opened, and workers can synchronously pick and place lenses, perform operations such as material picking, material placing, and processing, which can improve production efficiency. And due to the separation and enclosure of the protective cover 14, it will not cause harm to workers. The entire process can be achieved with a single drive source, and it has high energy efficiency. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
