A guide hole is provided on the top die; the upper die is arranged below the top die and includes upper die A, upper die B, and upper die C stacked in sequence from top to bottom. The upper die A, upper die B, and upper die C have the same size and specification, and are all provided with positioning holes matching the guide holes; the guide post passes through the guide hole and the positioning hole to connect the top die, upper die A, upper die B, and upper die C; the stamping fitting is arranged in the upper die A and upper die B, with the end facing downwards and directly opposite to the upper die C. A through channel is provided in the middle of the stamping fitting. The upper main body channel is a part insertion pipe, and the lower stamping end position channel is a part introduction pipe. The part introduction pipe is connected to the part insertion pipe, and an introduction structure is arranged at the connection part. The introduction structure adopts an inclined conical structure with an inclination angle of 15 - 30°, and the diameter gradually decreases from top to bottom until it is consistent with the inner diameter of the part introduction pipe; the stamping part is inserted into the part insertion pipe and the part introduction pipe. The guide post makes the die assembly positioning convenient and fast. The stamping fitting is used, and an introduction structure is arranged in the stamping fitting. Due to the adoption of an inclined conical structure, the stamping part can be easily inserted, which has the functions of positioning and guiding.

[0005] Further, in the above rapid assembly structure for a stamping die, fixing holes are provided on the top die, upper die A, upper die B, and upper die C, and fixing columns are arranged in the fixing holes to fix the die and improve the stability of the die structure.

[0006] Further, in the above rapid assembly structure for a stamping die, the stamping fitting is a quadrangular prism structure, and the stamping end position is set as a conical protrusion.

[0007] Furthermore, in the above-mentioned rapid assembly structure of a stamping die, the inner diameter of the pipe into which the part is inserted is larger than the diameters at both ends of the guiding structure and also larger than the inner diameter of the pipe for guiding the part. The pipes with diameters decreasing from large to small facilitate the insertion and assembly of the stamping parts and play a role in guiding and positioning.

[0008] Furthermore, in the above-mentioned rapid assembly structure of a stamping die, the diameter of the stamping part is less than or equal to the inner diameter of the pipe for guiding the part.

[0009] Furthermore, in the above-mentioned rapid assembly structure of a stamping die, several stamping fitting parts are provided. The stamping ends are aligned with the stamping areas of the product to be processed and are equal in number to the stamping positions of the product to be processed.

[0010] Furthermore, in the above-mentioned rapid assembly structure of a stamping die, a pressing groove is provided on the upper side surface of the stamping part. A circular cam is provided in the pressing groove. The cam is arranged below the inner part of the upper die B. A through hole is provided in the middle of the cam. A cam guide post is inserted into the through hole. The upper part of the cam guide post is inserted into the upper die B and the lower part is inserted into the upper die C. The cam and the cam guide post can increase the downward pressure of the stamping part and improve the stamping effect.

[0011] From the above technical solutions, it can be seen that the present utility model has the following beneficial effects: The rapid assembly structure of a stamping die described in the present utility model has a simple structure, simplifies the die structure, saves die costs, enables convenient and fast die assembly and positioning through the guide posts, uses stamping fitting parts, and an introduction structure is arranged in the stamping fitting parts.
