The upper die includes an upper template, an upper die pad, and an upper die fixing plate.

[0005] The upper template, upper mold pad, and upper mold fixing plate are provided with through mounting holes. The upper template is provided with a spring mounting plate detachably in the mounting holes. Nitrogen springs are provided at the four corners of the spring mounting plate. Guide pillars are connected to the nitrogen springs. The upper forming block is mounted on the four guide pillars. The upper forming block is provided with an upper forming groove for forming the workpiece.

[0006] The upper mold fixing plate is provided with a square-shaped upper trimming block, the upper trimming block is provided with trimming cutting edges for trimming the four sides of the workpiece, and a feeding edge cutting knife block is provided around the trimming cutting edges on the upper trimming block.

[0007] The lower mold includes a lower mold base plate, a lower mold base plate is provided on the lower mold base plate, and a lower mold forming block is detachably provided on the lower mold base plate; the lower mold forming block is surrounded by a lower cutting edge that matches the trimming cutting edge on the upper forming block;

[0008] The lower die forming block has a blanking edge cutting blade block on each of the four sides of the lower edge, which is matched with the corresponding blanking edge cutting blade block;

[0009] The upper die plate is equipped with an upper punch for punching the center through hole of the workpiece, and the spring mounting plate and the upper forming block are equipped with clearance holes to avoid the upper punch; the lower die forming block is equipped with a punching die button that cooperates with the upper punch.

[0010] As a preferred embodiment, the upper forming block has a pair of stamped limiting posts on the inner side regions of the four guide posts.

[0011] As a preferred embodiment, the spring mounting plate is provided with two limiting holes that respectively cooperate with a pair of stamped limiting posts.

[0012] As a preferred embodiment, the lower die holder is provided with a side waste discharge plate at each cutting edge cutting block.

[0013] As a preferred embodiment, the lower die holder is provided with a central waste discharge plate for discharging punching waste.

[0014] The beneficial effects of this utility model are:

[0015] Because the upper mold plate, upper mold pad, and upper mold fixing plate have through mounting holes, and the upper mold plate has a detachable spring mounting plate in the mounting holes, with nitrogen springs at the four corners of the spring mounting plate, and guide pillars connected to the nitrogen springs, the upper forming block is mounted on the four guide pillars. The upper forming block has an upper forming groove for forming the workpiece. The upper mold fixing plate has a square-shaped upper trimming block with trimming edges for trimming the four sides of the workpiece. Around the trimming edges, there is a feeding edge cutting blade. The lower mold includes a lower mold base plate with a lower mold seat. The lower mold base has a detachable lower mold forming block. The lower mold forming block has lower cutting edges that mate with the trimming edges of the upper forming block. Around the lower cutting edges, there is a feeding edge cutting blade that mates with the corresponding feeding edge cutting blade. This design ensures that the upper forming block does not suspend too much air and runs smoothly, thereby increasing the stability and safety of the mold. It also facilitates maintenance by using quick-release mechanisms on the reverse side of the nitrogen springs for easy disassembly.

[0016] Because a pair of stamped limiting posts are provided on the inner side of the four guide posts on the upper forming block, the movement of the upper forming block is more stable.

[0017] The spring mounting plate is provided with two limiting holes that respectively cooperate with a pair of stamped limiting posts, which further ensures the final machining accuracy. Attached Figure Description
