the utility model provides an insert formula sculpture cutting die, includes sculpture cutting die body, sculpture cutting die body include mould cavity base and set up in sculpture cutter body on the mould cavity base, it has carving tool and movable thimble pad to inlay on the sculpture cutter body, movable thimble pad is located the both sides of carving tool, be provided with the correspondence on the mould cavity base the ejecting subassembly of activity thimble pad, ejecting subassembly includes that elasticity excellent force glues and locates elasticity excellent force glues on, and with the balanced steel sheet that activity thimble pad is connected.

Realize above-mentioned technical scheme, elasticity dominant force is glued and is played the spring action for elastic support is on balanced steel sheet, balanced steel sheet is used for balancing every inlayed thimble, makes balanced steel sheet press movable thimble pad, when the product is die-cut, pushes down the sheet product earlier, then the blade point on the carving tool just can cut the product, the product is difficult to produce the extrusion like this, in addition, the back is cut to the blade product, when lifting the mould, also the blade point withdraws from earlier, the product is being pressed to the thimble, slowly withdraws from, the drawing of patterns of also being convenient for. The flatness and the section flatness of the product are high, the product can be made very small, the minimum value can be 0.7 x 0.7mm, and the product can not be made by a conventional die.

As a preferable aspect of the present application, the mold cavity base and the engraving blade body are fixed together by screws.

As a preferred scheme of this application, it has the location guide post to inlay on the sculpture cutter body, the location guide post is located the both sides of activity thimble pad.

The technical scheme is realized, and the carving cutter body and the bottom plate are positioned when the carving cutter is used for carving.

As an optimal scheme of this application, mould cavity base has been seted up and has been held elasticity excellent power glue with the recess of balanced steel sheet.

The technical scheme is realized so as to facilitate the installation of the elastic force-exerting rubber and the balance steel sheet.

As an optimal scheme of this application, activity thimble pad comprises a plurality of thimbles, and is a plurality of the thimble is located respectively the both sides of carving tool.

Realize above-mentioned technical scheme for support on the sheet of carving tool both sides to the carving tool carves.

The utility model has the advantages that:

the utility model can not only press the product by the movable thimble when punching the product, but also cut the product by the knife edge on the graver, thus the punched product is not easy to generate extrusion deformation, and after cutting, the product is pressed by the thimble when lifting the die, and the knife edge is withdrawn slowly first, thereby facilitating the demoulding; and the punched product not only has high integral flatness and section flatness, but also can be made very small, and the minimum value can be 0.7 x 0.7 mm.
