[0054] like Figure 6 As shown, in one embodiment, the servo linear rail safety door without upper rail beam further includes a guide structure 400, which is disposed in the accommodating cavity, and the upper and lower ends of the frame 110 are both connected with a guide structure 400, and the upper and lower ends of the movable door plate 200 are both connected with the corresponding guide structure 400. By arranging the guide structure 400 at the upper and lower ends of the frame 110, and connecting the guide structure 400 with the movable door plate 200, the movement of the movable door plate 200 relative to the safety door body 100 is guided by the guide structure 400, thereby improving the reliability and stability of the movable door plate 200 when it moves relative to the safety door body 100.

[0055] like Figure 6 As shown, specifically, each guide structure 400 includes a linear guide rail 410, a guide bracket and a guide rail slider 430. The linear guide rail 410 is fixedly connected to the frame 110; one end of the guide rail bracket 420 is fixedly connected to the movable door panel 200; one end of the guide rail slider 430 is fixedly connected to the other end of the guide rail bracket 420, and the other end of the guide rail slider 430 is provided with a guide groove, and the linear guide rail 410 is guided and matched with the guide groove. Further, two opposite groove side walls of the guide groove are provided with limiting protrusions, and two opposite side surfaces of the linear guide rail are provided with limiting grooves, and the limiting grooves extend along the extension direction of the linear guide rail 410, and the limiting protrusions are matched with the limiting grooves in a concave-convex manner.

[0056] like Figure 6As shown, by arranging a linear guide rail 410 on the frame 110, arranging a guide rail bracket 420 on the movable door panel 200, and fixing a guide rail slider 430 on the guide rail bracket 420, the linear guide rail 410 is matched with the guide groove in the guide rail slider 430 to limit the movable door panel 200 and guide the movement of the movable door panel 200 relative to the safety door body 100. In this embodiment, the guide rail bracket 420 is set as an L-shaped structure, one side of the guide rail bracket 420 is fixedly connected to the movable door panel 200 by bolts or welding; the other side of the guide rail bracket 420 is provided with a through hole, and the guide rail slider 430 is provided with at least two bolt holes spaced apart from each other, and the bolts pass through the through holes on the guide rail bracket 420 and are threadedly connected with the bolt holes on the guide rail slider 430, thereby realizing the fixed connection between the guide rail bracket 420 and the guide rail slider 430. In addition, by setting a limiting protrusion on the side wall of the guide groove and setting a limiting groove on the side of the linear guide rail, the limiting protrusion and the limiting groove are matched to limit the guiding cooperation between the guide rail slider 430 and the linear guide rail, thereby improving the stability of the connection between the two.

[0057] like Figure 3 As shown, in one embodiment, the driving assembly 300 includes a servo motor 310, a driving wheel, a driven wheel and a synchronous belt 320. The servo motor 310 is disposed in the accommodating cavity and is connected to the safety door body 100; the driving wheel is fixedly connected to the output shaft of the servo motor 310; the driven wheel is fixedly connected to the safety door body 100 and is spaced apart from the driving wheel; the synchronous belt 320 is arranged between the driving wheel and the driven wheel, and the movable door panel 200 is fixedly connected to the synchronous belt 320.

[0058] In this embodiment, the servo motor 310 is used to drive the driving wheel to rotate, and a synchronous belt 320 is stretched between the driving wheel and the driven wheel to drive the synchronous belt 320 to move. The movable door plate 200 is fixedly connected to the synchronous belt 320, so that the movement of the synchronous belt 320 drives the movable door plate 200 to move relative to the safety door body 100.

[0059] like Figure 7As shown, further, the servo linear rail safety door without upper rail crossbeam also includes a switch assembly 500, and the switch assembly 500 includes a mounting frame 510 and a limit switch 520, the mounting frame 510 is fixedly connected to the safety door body 100; the limit switch 520 is fixedly connected to the mounting frame 510; wherein, when the movable door plate 200 moves to a preset position, the contact of the limit switch 520 is triggered to control the servo motor 310 to be turned off. Specifically, the mounting frame 510 is fixedly connected to the bottom of the frame 110. By arranging the limit switch 520 on the servo linear rail safety door without upper rail crossbeam, the moving stroke of the movable door plate 200 is monitored. When the movable door plate 200 moves to a preset position relative to the safety door body 100, the contact of the limit switch 520 is triggered, so that the servo motor 310 can be turned off, so that the servo motor 310 no longer runs, thereby stopping the movable door plate 200 from moving. In this way, the servo linear rail safety door without an upper rail crossbeam can be protected, thereby increasing the service life of the servo linear rail safety door without an upper rail crossbeam.

[0060] like Figure 3 As shown, further, the movable door panel 200 includes a door frame 210 and a shielding plate 220, and the door frame 210 is configured with a mounting notch with an opening at one end; the shielding plate 220 is arranged at one end of the door frame 210 away from the opening; wherein, a safety switch 600 is arranged at the end of the shielding plate 220 away from the opening, and when the movable door panel 200 moves into the accommodating cavity, the safety switch 600 is triggered and the circuit of the die-casting machine is disconnected. The door frame 210 is used to improve the overall strength of the movable door panel 200, and the door frame 210 is also used to connect with the guide structure 400 and the drive assembly 300. The shielding plate 220 is installed by setting a mounting notch on the door frame 210. It can be understood that in this embodiment, the length of the door frame 210 is greater than the length of the shielding plate 220, and a reinforcing rib plate is arranged at the corner formed by the door frame 210 and the shielding plate 220 to improve the strength of the movable door panel 200. By setting a safety switch 600 on the shielding plate 220, when the movable door panel 200 is opened, the circuit of the die casting machine is cut off by the safety switch 600, so that the die casting machine cannot be operated, thereby improving the safety performance when repairing the die casting machine.

[0061] like Figure 7As shown, in one embodiment, the movable door panel 200 further includes a protective cover plate 230, one end of which is fixedly connected to the bottom end of the shielding plate 220, and the other end of the protective cover plate 230 is bent in a direction away from the protective cover plate 230, and then bent again and extended downward so that a protective groove is defined between the protective cover plate 230 and the shielding plate 220, and at least part of the limit switch 520 is disposed in the protective groove. By arranging the protective cover plate 230 on the movable door panel 200 to protect the limit switch 520 disposed in the anti-slip groove, the service life of the limit switch 520 and the reliability of the operation of the limit switch 520 are ensured.
