The knife mold includes a knife template and a cutting knife arranged below the knife template.

The upper platen includes a base and a support plate fixed on the bottom of the base, the base cooperates with the support plate to form the installation groove; the force receiving surface is the lower surface of the support plate.

Air holes are provided on the knife template, and through holes are arranged on the support plate to connect the air holes with the installation groove when the knife template is in contact with the force-bearing surface.

The installation groove runs through the two end walls of the upper pressing plate.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model is provided with a mounting groove on the upper pressing plate, and by installing the cutter shaft in the installing groove, the upper pressing plate can be directly used as a punching head without additional punch steel parts, which can effectively reduce its weight and improve the Its moving speed; moreover, by installing the cutter shaft in the installation groove, it can make its structure relatively compact, so as to effectively reduce its volume and facilitate installation on the cutting machine; in addition, by setting the force-bearing surface on the upper platen , the cutting die can directly transmit the top pressure it receives to the upper platen, so as to avoid the direct force on the cutter shaft, which can effectively prolong the service life of the cutter shaft; a moving component can also be installed in the installation groove, so that the moving component can drive the cutter shaft Move relative to the upper platen to improve the flexibility and convenience of the die cutter.
