[0048] Example 2:

[0049] This embodiment provides a stamping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0050] Molding mold 4 includes:

[0051] The outer mold body 41 is annular and is mounted on the lower mold base 3.

[0052] The inner mold body 42 is set on the lower mold base 3 and is located inside the outer mold body 41. The upper part of the inner mold body 42 is provided with a concave surface 421.

[0053] The stamping chamber 10 is formed between the concave surface 421, the outer mold body 41, and the mating surface of the punch mold 2.

[0054] As can be seen from this embodiment, the molding die 4 includes an outer mold body 41 and an inner mold body 42;

[0055] The outer mold body 41 is a ring-shaped cast steel structure. The inner mold body 42 is installed on the lower mold body and is slidably connected to the inner ring of the outer mold body 41. The gap between the mating surfaces of the outer mold body 41 and the inner mold body 42 is small, which can effectively eliminate burrs generated during the stamping process.

[0056] Furthermore, the upper part of the inner mold body 42 is milled to form a concave surface 421, which, together with the inner wall of the outer mold body 41 and the punch mold 2, forms a stamping chamber 10 to form the product.

[0057] Example 3:

[0058] This embodiment provides a stamping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0059] The unloading structure 5 includes;

[0060] Air intake duct 51 is provided on outer mold body 41;

[0061] An air outlet 52 is provided on the inner mold body 42, and the air outlet 52 is located at the lower end of the inner mold body 42 and extends to the bottom of the concave surface 421.

[0062] An annular air passage 53 is provided at the lower end of the inner mold body 42 and is connected to the outlet air passage 52, and the inlet air passage 51 is connected to the annular air passage 53.

[0063] Ejector rod 54 is installed inside air outlet 52;

[0064] The air intake duct 51 is connected to an external high-pressure air source.

[0065] As can be seen from this embodiment, the unloading structure 5 includes an air inlet 51, an air outlet 52, an annular air outlet 53, and an ejector rod 54;

[0066] The air inlet 51 is formed on the outer mold body 41, and the air outlet 52 and the annular air outlet 53 are both formed on the lower part of the inner mold body 42.

[0067] Furthermore, the annular air passage 53 is formed on the lower side of the air outlet 52 and is connected to the air inlet 51. In use, an external high-pressure air source enters the annular air passage 53 through the air inlet 51 and is transported to the air outlet 52 through the annular air passage 53.

[0068] The ejector rod 54 is installed on the air outlet 52. When in use, the punch mold 2 is raised a certain height away from the end face of the inner mold body 42, but is still inside the outer mold body 41. At this time, air enters through the air inlet 51. The high-pressure air source pushes the ejector rod 54 upward in the air outlet 52 and separates the product from the inner mold body 42. At the same time, the punch mold 2 will press against the product wall and the product will fly out.
