[0037] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the utility model and are not limited to the scope of the utility model. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0038] like Figure 2 and Figure 3 , which is a schematic structural diagram of an embodiment of the utility model, provides a nested mold structure, including an upper mold mechanism and a lower mold mechanism arranged opposite to the upper mold mechanism.

[0039] The upper mold mechanism includes an upper mold base 1, a first heat insulation plate 2, an upper mold plate 3, a first heating component 5 installed in the upper mold plate 3 and a punch component 4 embedded in the upper mold plate 3. The upper mold plate 3 and the first heat insulation plate 2 are fixed to the upper mold base 1 by multiple screws, and the first heat insulation plate 2 is arranged between the upper mold plate 3 and the upper mold base 1.

[0040] The upper die base 1 is fixedly connected to the machine platform and is used to fix the entire upper die mechanism. The first heat insulation board 2 is used to block the heat transfer between the upper die plate 3 and the machine platform to avoid affecting the machine platform. The first heating assembly 5 includes a plurality of heating rods, which are arranged in the mounting holes on the upper die plate 3 and connected to a power source. The upper die plate 3 is heated by the first heating assembly 5 to heat the punch component 4, thereby performing hot stamping forming on the product 13.

[0041] Among them, the punch component 4 is a plate-like structure and the lower end surface protrudes from the lower end of the upper mold plate 3. The punch component 4 is used to punch the product 13 on the lower mold mechanism, which can prevent the upper mold position on the periphery of the product from being subjected to large-tonnage stamping pressure, causing the mold to break.

[0042] In order to facilitate the installation of the punch component 4, a limiting groove 3-1 for the punch component 4 to be placed is provided on the upper template 3. The limiting groove 3-1 is formed by the upper template 3 being recessed upward. Specifically, the punch component 4 is fixed to the upper template 3 by multiple screws 12.

[0043] The lower die mechanism includes a lower die plate 6 arranged opposite to the punch component 4, a lower pad 7 arranged below the lower die plate 6, a second heat insulation plate 8 arranged below the lower pad 7, a lower clamping plate 9 arranged below the second heat insulation plate 8, and a lower die base 11 supported below the lower clamping plate 9. The lower clamping plate 9, the second heat insulation plate 8, the lower pad 7 and the lower die plate 6 are fixedly connected by a plurality of screws, and the lower clamping plate is fixedly connected to the lower die base 11 by a plurality of screws 12. The area of ​​the lower die plate 6 is larger than that of the punch component 4, and is used to support the product 13.

[0044] A second heating assembly 10 is provided in the lower pad 7. The second heating assembly 10 includes a plurality of heating rods. The heating rods are arranged in mounting holes on the lower pad 7 and connected to a power source. The lower pad 7 is heated by the second heating assembly 10 to heat the lower mold plate 6, thereby achieving hot stamping. The second heating assembly 10 is arranged in the lower pad 7, so that the product 13 can be heated evenly. Compared with arranging the second heating assembly 10 in the lower mold plate 6, the product can be heated more evenly, thereby improving the stamping effect.

[0045] In this example, the lower die base 11 includes two upper and lower support plates 11-1 and a plurality of feet 11-2 disposed between the two support plates 11-1. The lower support plate 11-1 is connected to the machine platform. The feet 11-2 can increase the height of the lower die mechanism so that its height meets the stamping requirements.

[0046] In summary, the mold structure stamps the product through the cooperation of the punch component and the lower mold plate, so that the force structure of the mold is located in the middle position during stamping, reducing the influence of the upper mold position on the periphery of the large-tonnage stamping pressure product, avoiding mold breakage, and at the same time improving the stamping effect and product quality.

[0047] The above examples are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
