[0027] In order to make the purpose, technical scheme and advantages of the implementation of the utility model clearer, the utility model will now be further described in detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the utility model. The specific implementation scheme of the utility model is as follows:

[0028] A double-ring-buckle split-inlaid replaceable forging die comprises an upper die frame 1 and a lower die frame 1, wherein the upper and lower die frames 1 are provided with a die cavity 21 on their opposite end faces, and the die cavity 21 is arranged in a rectangular parallelepiped structure; the die frame 1 on the adjacent sides of the die cavity 21 is provided with a positioning groove 22, and the two positioning grooves 22 are both connected to the die cavity 21, and the outer side walls of the positioning grooves 22 are inclined structures; a die core 3 is arranged in the die cavity 21, and the shape of the die cavity 21 and the die core 3 are adapted, and after the die core 3 is installed, there is a gap of 1 mm with the side wall of the die cavity; the locking blocks 5 are all installed in the positioning groove 22 by screws, so that the inclined surface of the locking block 5 cooperates with the inclined surface of the positioning groove 22, and the die core 3 is squeezed against the other side wall of the die cavity 21.

[0029] The mold core 3 is directly installed in the mold cavity 21, and the mold core 3 is squeezed and fixed in the mold cavity 21 by using screws and the cooperation between the inclined surface of the locking block 5 and the inclined surface of the positioning groove 55. This not only reduces the processing difficulty, but also reduces the stress state of the mold cavity during operation, increases the fatigue resistance of the mold, and extends the service life of the mold.

[0030] It should be noted that the screw is a hexagon socket head screw A4, and the locking block 5 is provided with a countersunk hole A that matches the hexagon socket head screw A4. The hexagon socket head screw A4 passes through the countersunk hole A and is connected to the mold frame 1 through threaded engagement to fix the locking block 5.

[0031] A core reference 7 is provided at one corner of the core 3, and a frame reference 8 is provided at one corner of the cavity 21; this facilitates assembly by workers and prevents errors during assembly.

[0032] The outer end surface of the mold core 3 is provided with a threaded lifting hole 6 to facilitate the removal of the mold core from the mold frame.

[0033] A countersunk hole B is provided on the mold core 3, and a hexagon socket head screw B9 is arranged in the countersunk hole B. The hexagon socket head screw B9 passes through the countersunk hole B and is connected to the mold frame 1 through threaded engagement; after the positioning is completed, the mold core 3 is connected and fixed to the mold frame 1 by the hexagon socket head screw B9, so that the gap in the threaded connection can be avoided, which causes shaking within a certain range and improves the accuracy.

[0034] The working principle and working process of the utility model are as follows:

[0035] First, according to the positions of the core reference 7 and the frame reference 8, the core 3 is placed in the cavity 21, and then the locking block 5 is placed in the positioning groove 22 on the right. As the two inclined surfaces slide, the locking block 5 gradually moves to the left, and then the core 3 moves to the left under pressure until it is squeezed to the left side wall of the cavity 21. Similarly, the same operation is performed on the other locking block 5, which is placed in the positioning groove 22 on the lower side and is squeezed to the upper side wall of the cavity 21 by the core. The locking block 5 is connected and fixed to the frame 1 by the hexagon socket head screw A4, and then the core 3 is connected and fixed to the frame 1 by the hexagon socket head screw B9 to complete the operation.
