Description

Technical Field

[0001] This utility model relates to the field of die casting technology, and in particular to a die casting mold pre-reset detection device. Background Technology

[0002] Die casting is a metal casting process that uses a mold cavity to apply high pressure to molten metal. During die casting, the accuracy of mold resetting directly affects product quality and production efficiency. If the mold is not reset properly, the core-pulling slider may collide with the ejector pin, which will not only damage the mold but also affect the molding effect of the product.

[0003] A search revealed a utility model patent with Chinese patent number CN212792947U, which discloses a pre-reset detection device for die-casting molds.

[0004] Compared with existing technologies, the utility model patent with Chinese patent number CN212792947U uses two detection methods to perform multi-level detection. Combined with the monitoring of the controller, it can effectively ensure the accuracy of detection and reset. At the same time, when one of the two detection structures malfunctions or is misaligned, it can be detected and corrected in time, while the other detection structure can still perform stable and accurate reset detection.

[0005] However, in actual use, the above-mentioned device is not easy to perform multi-point reset of the mold. In practical applications, the reset of the die-casting mold may involve multiple key points, and these key points need to be reset simultaneously and accurately to ensure the normal operation of the mold. However, the design of the device focuses more on the overall reset detection and fails to fully consider the need for multi-point reset, which will cause the die-casting mold reset deviation and lead to mold damage. Therefore, it is necessary to propose a die-casting mold pre-reset detection device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in performing multi-point reset of molds, and to propose a pre-reset detection device for die-casting molds.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A die-casting mold pre-reset detection device includes a base, a circular plate movably connected to the upper part of the base, a telescopic motor fixedly connected to the side of the circular plate away from the base, an upper mold head movably connected to the output shaft end of the telescopic motor, and a lower mold base movably connected to the side of the base near the upper mold head. A multi-point bow-shaped reset detection assembly is provided on the circular plate, comprising an annular plate movably connected to the circular plate and multiple bow-shaped arms movably connected to the annular plate. The fan-shaped rotation of the bow-shaped arms performs reset detection on the mold, and this multi-point reset detection greatly improves the accuracy and stability of mold reset.

The size of the lower mold base is adapted to the size of the upper mold head, and the downward movement of the upper mold head will fit into the inner side of the lower mold base.

[0013] Multiple electric telescopic rods are fixedly connected to the side of the circular plate near the base. The multiple electric telescopic rods are evenly distributed around the circumference of the circular plate. The ends of the multiple electric telescopic rods away from the circular plate are fixedly connected to the annular plate. The activation of the electric telescopic rods will cause the annular plate to move back and forth in the vertical direction.

[0014] Multiple motors are fixedly connected to the side of the annular plate near the base. The multiple motors are evenly distributed around the circumference of the annular plate. The end of the motor away from the annular plate is fixedly connected to the bow-shaped arm. The fan-shaped rotation of the bow-shaped arm will perform multi-point reset detection on the mold.

[0015] Multiple hollow tubes are fixedly connected to the side of the triangular tube away from the base. The end of the hollow tube away from the triangular tube is fixedly connected to the servo motor. The end of the servo motor away from the hollow tube is fixedly connected to the rotating rod. A flexible pad is fixedly connected to the outside of the rotating rod. The rotating rod will push the mold to the designated position, which can ensure that the mold can accurately return to the initial position after each use.

[0016] A circular tube is fixedly connected to the outside of the hollow tube. The end of the circular tube away from the base is fixedly connected to a flexible limiting plate. The size of the flexible limiting plate is adapted to the size of the rotating rod, and the flexible limiting plate can limit the position of the rotating rod.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, by setting up a multi-point bow-shaped reset detection component, the fan-shaped rotation of the bow-shaped arm will perform multi-point reset detection on the mold, which will greatly improve the accuracy and stability of mold reset.

A multi-point bow-shaped reset detection component is provided on the circular plate 3, including an annular plate 10 movably connected to the circular plate 3 and multiple bow-shaped arms 12 movably connected to the annular plate 10. The fan-shaped rotation of the bow-shaped arms 12 will perform reset detection on the mold. The fan-shaped rotation of the bow-shaped arms 12 will perform multi-point reset detection on the mold, which will greatly improve the accuracy and stability of mold reset. A fixed-point reset detection component is provided on the base 1, including a servo motor 14 and a rotating rod 15 movably connected to the base 1, and a flexible limiting plate 18 movably connected to the base 1. The start of the servo motor 14 will drive the rotating rod 15 to move in the horizontal direction, and the rotating rod 15 will push the mold to the designated position.

[0028] Multiple support columns 2 are fixedly connected to the side of the base 1 near the circular plate 3. The multiple support columns 2 are evenly distributed around the circumference of the base 1. The ends of the multiple support columns 2 away from the base 1 are fixedly connected to the circular plate 3. The support columns 2 mainly serve to support the circular plate 3.

[0029] The output shaft of the telescopic motor 4 is fixedly connected to a connecting pipe 5. The end of the connecting pipe 5 away from the circular plate 3 is fixedly connected to the upper mold head 6. The start of the telescopic motor 4 can drive the upper mold head 6 to move back and forth in the vertical direction.

[0030] A triangular tube 7 is fixedly connected to the side of the base 1 near the upper mold head 6. The side of the triangular tube 7 away from the base 1 is fixedly connected to the lower mold base 8. The size of the lower mold base 8 is adapted to the size of the upper mold head 6. The downward movement of the upper mold head 6 will fit into the inner side of the lower mold base 8.

[0031] Multiple electric telescopic rods 9 are fixedly connected to the side of the circular plate 3 near the base 1. The multiple electric telescopic rods 9 are evenly distributed around the circumference of the circular plate 3. The ends of the multiple electric telescopic rods 9 away from the circular plate 3 are fixedly connected to the annular plate 10. The activation of the electric telescopic rods 9 will drive the annular plate 10 to move back and forth in the vertical direction.

[0032] Multiple motors 11 are fixedly connected to the side of the annular plate 10 near the base 1. The multiple motors 11 are evenly distributed around the annular plate 10. The end of the motor 11 away from the annular plate 10 is fixedly connected to the bow-shaped arm 12. The fan-shaped rotation of the bow-shaped arm 12 will perform multi-point reset detection on the mold.

[0033] In this embodiment, the fan-shaped rotation of the bow arm 12 performs multi-point reset detection on the mold, which greatly improves the accuracy and stability of mold reset. It allows for simultaneous detection at multiple key locations on the mold. Specifically, the base 1 primarily provides support, and the support column 2 connects the base 1 and the circular plate 3. When the telescopic motor 4 starts, the output shaft of the telescopic motor 4 drives the connecting pipe 5 to move back and forth in the vertical direction.

The size of the upper mold head 6 is adapted to the size of the lower mold base 8, and the contact between the upper mold head 6 and the lower mold base 8 is thus complete. In the die casting process, after the die casting is completed, the upper die head 6 will retract to its original state due to the action of the telescopic motor 4. At this time, the electric telescopic rod 9 will start, and the start of the electric telescopic rod 9 will drive the annular plate 10 to move back and forth in the vertical direction. When it moves to the appropriate position, the annular plate 10 will stop. At this time, the motor 11 will start, and the start of the motor 11 will drive the bow arm 12 to move in a fan shape. The fan-shaped rotation of the bow arm 12 will perform multi-point reset detection on the mold, which will greatly improve the accuracy and stability of mold reset. It can simultaneously detect multiple key positions of the mold, ensuring that each point can be accurately reset according to the predetermined bow path.

The size of the flexible limiting plate 18 is adapted to the size of the rotating rod 15. The flexible limiting plate 18 can limit the position of the rotating rod 15.

[0037] In this embodiment, the start of the servo motor 14 will drive the rotating rod 15 to move horizontally. The rotating rod 15 will push the mold to a designated position, ensuring that the mold can accurately return to the initial position after each use. The hollow tube 13 connects the triangular tube 7 and the servo motor 14. After the servo motor 14 is started, the output shaft end of the servo motor 14 will drive the rotating rod 15 to rotate. Multiple rotating rods 15 rotate simultaneously. By setting the rotation angle of the servo motor 14, the rotating rod 15 will rotate to a designated position, so that the mold can be pushed to the designated position by the rotation of the rotating rod 15, thus ensuring that the mold can accurately return to the initial position after each use.
