Technical Field
[0001] This utility model relates to the field of mold auxiliary accessories technology, and in particular to a corner chamfering device for mold manufacturing. Background Technology
[0002] A chamfering device for mold manufacturing is an auxiliary device specifically designed for mold processing. Its main function is to chamfer the edges and corners of the mold. This device is usually installed on CNC machine tools or manual grinding machines. It can ensure a smooth transition at the edges and corners of the mold, reduce stress concentration, and thus improve the durability and safety of the mold.
[0003] Traditional chamfering devices have limitations in applicability, typically only capable of chamfering molds of specific sizes or shapes. When faced with molds of different specifications, the equipment often needs to be replaced or adjusted, resulting in low operational flexibility. Furthermore, many traditional chamfering devices rely heavily on manual operation and have low levels of automation. This not only increases the workload of operators but also easily introduces processing errors due to the instability of human operation.

Through a precise servo motor control system, it achieves high-precision position control and multi-axis adjustment of the grinding head, ensuring the consistency and accuracy of the chamfering. It can also adapt to molds of different sizes and shapes for multi-angle chamfering. Furthermore, the synchronous motor-driven first threaded rod ensures the synchronous and uniform movement of the fixing plate in the horizontal direction, maintaining the consistency of the chamfering on both sides of the mold and improving processing accuracy. The turntable driven by the first servo motor achieves precise rotational positioning of the mold, increasing processing flexibility and adaptability. The design of the fixing plate provides stable support for the mold, reducing vibration and improving chamfering quality. The first electric push rod can adjust the position of the fixing plate according to the mold size and shape, thus improving the overall automation and ease of operation of the device.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A chamfering device for mold manufacturing includes a base, a mounting bracket, and a grinding head. A second mounting groove is formed in the middle of the lower end of the mounting bracket. A second servo motor is fixedly connected to the inner wall of one side of the second mounting groove. A second threaded rod is disposed inside the second mounting groove. The output end of the second servo motor is fixedly connected to the middle of one side of the second threaded rod. The other side of the second threaded rod is rotatably connected to the inner wall of the other side of the second mounting groove. A second sliding sleeve is threadedly connected to the outer wall of the second threaded rod. The upper surface of the lower end of the second sliding sleeve slides against the middle of the lower surface of the mounting bracket.

The outer wall of the first sliding block slides against the inner wall of the first sliding groove.
[0018] The above technical solution ensures that the mounting frame can slide precisely along the predetermined trajectory of the support frame through the cooperation of the first sliding block and the first sliding groove, thereby achieving accurate positioning. In addition, the sliding fit design reduces friction and jumping during the movement, making the movement of the mounting frame more stable.
