Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The bottom end of the splint 5 is fixedly connected to a sliding rod 57 that drives the splint 5 to move. The bottom of the die-casting table 1 is fixedly installed with a support frame 52 that supports the servo motor 510. The top of the support frame 52 is fixedly installed with a servo motor 510 that can drive the turntable 59 to rotate. The servo motor 510 is an existing structure and can be implemented by technicians in this field. Since it is an existing technology, it will not be described in detail in this case. The top end of the output shaft of the servo motor 510 is fixedly connected to a turntable 59 that drives the slide 58 to move. The turntable 59 is rotatably connected to the bottom end of the die-casting table 1. A limit assembly is set on the outer wall of the front surface of the turntable 59, and the limit assembly includes a triangular clamp block 56.

[0032] Reference Figure 1 、 Figure 2 and Figure 3 The rear surface of the splint 5 is provided with an adjustment component, which includes a threaded rod 6 that drives the pressure plate 61 to move. The threaded rod 6 passes through and is threadedly connected to the front surface of the splint 5. The splint 5 supports the threaded rod 6. The rear surface of the threaded rod 6 is rotatably connected to the pressure plate 61 that can clamp the static mold 4 in position.

[0033] Reference Figure 1 、 Figure 3 and Figure 4 The top of the front of the turntable 59 is penetrated and provided with a slide groove 58 that can drive the slide bar 57 to move. The slide bar 57 is slidably connected to the inner wall of the slide groove 58. The slide groove 58 is set to an arc shape. By setting it to an arc shape, the slide groove 58 can drive the slide bar 57 to move when it rotates. At the same time, the clamping plate 5 is penetrated and slidably connected to the top of the die-casting table 1, so that the slide bar 57 can drive the clamping plate 5 to move back and forth, pressing the pressure plate 61 against the static mold 4. The triangular clamping block 56 is fixedly connected to the outer wall of the front surface of the turntable 59. There are multiple groups of triangular clamping blocks 56. Multiple groups of triangular clamping blocks 56 are arranged in a ring array on the outer wall of the turntable 59. The triangular clamping blocks 56 are set to a triangular shape. Multiple groups of triangular clamping blocks 56 can limit the turntable 59 to prevent the turntable 59 from rotating, thereby improving stability. The front surface of the die-casting table 1 is fixedly connected with a positioning block 51, which provides support.

[0034] Reference Figure 1 、 Figure 3 and Figure 4 The bottom end of the positioning block 51 is slidably connected with a limiting block 55 that can be stuck in the outer wall of the triangular block 56 to limit the turntable 59. The top of the limiting block 55 is fixedly connected with a guide rod 54 that drives the limiting block 55 to move. The top of the guide rod 54 is slidably connected with a positioning plate 53 that drives the guide rod 54 to move up and down. The positioning plate 53 can slide on the top of the die-casting table 1 to position the guide rod 54 and the limiting block 55 that slides out of the triangular block 56. At this time, the turntable 59 can be easily rotated. The rear surface and bottom end of the limiting block 55 are provided with a card groove adapted to the triangular block 56. The limiting block 55 is clamped on the outer wall of the triangular block 56. The triangular block 56 and the turntable 59 can be limited by moving the limiting block 55 downward to clamp it on the outer wall of the triangular block 56.

[0035] Reference Figure 1 、 Figure 2 and Figure 3 The pressure plate 61 is arranged on the outer wall of the static mold 4, and the rear surface of the threaded rod 6 is fixedly connected with an anti-slip sleeve that provides an anti-slip effect, which can conveniently and stably drive the threaded rod 6 to rotate.

[0036] Working principle: When in use, the positioning plate 53 is moved upward to drive the guide rod 54 and the limit block 55 to move, so that the limit block 55 moves out of the triangular block 56, and the limit of the triangular block 56 and the turntable 59 is released. At this time, the positioning plate 53 is moved to slide onto the die-casting table 1 to support the positioning plate 53. At this time, the servo motor 510 at the top of the support frame 52 is started, and the output shaft of the servo motor 510 drives the turntable 59 to rotate, and the slide groove 58 at the top of the front of the turntable 59 is in an arc shape. When the turntable 59 rotates, the slide rod 57 on the inner wall of the slide groove 58 moves under the drive of the slide groove 58. Since the splint 5 passes through and is slidably connected to the front of the top of the die-casting table 1, the slide rod 57 is fixedly connected to The bottom end of the splint 5, so the movement of the slide bar 57 will drive the splint 5 to move forward and backward. As the turntable 59 rotates, the movement of the slide bar 57 in the slide groove 58 makes the splint 5 move toward the static mold 4, and finally presses the pressure plate 61 against the outer wall of the static mold 4. By setting multiple groups of splints 5, the static mold 4 can be stably clamped at the center to achieve the initial positioning of the static mold 4. At this time, the positioning plate 53 can be moved out of the die-casting table 1 and then moved downward to drive the limit block 55 to move downward and be stuck outside the triangular block 56, so that the triangular block 56 and the turntable 59 are stably limited, thereby improving the stability during die-casting, preventing the static mold 4 from moving, and further improving the processing quality.

[0037] Then, by rotating the threaded rod 6 that passes through and is threadedly connected to the front surface of the splint 5, when the threaded rod 6 is rotated, the threaded rod 6 moves back and forth under the action of the threads on the splint 5, thereby driving the pressure plate 61 to move back and forth, adjusting the distance between the pressure plate 61 and the static mold 4, and clamping the static mold 4 in place. When the static molds 4 are of different sizes, the position of the pressure plate 61 can be adjusted at the same time, and static molds 4 of different sizes can be positioned, thereby improving flexibility and applicability.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
