Claims (1)

[Scope of utility model registration request] A lower inner die having a general shape recess on the upper surface corresponding to one side of the cast or forged product, and a lower cutting blade surrounding the lower inner die and corresponding to the burr cutting position of the molded product on the inner edge of the upper end. A lower cutting blade die having a lower cutting edge die is supported on a base so as to be relatively movable in the vertical direction, and a lifting table that is driven up and down above the base has a total mold shape corresponding to the other side of the molded product. An upper inner die having a recess on the lower surface is supported via a resilient mechanism, the upper inner die is movable relative to the upper inner die in the vertical direction, surrounds the upper inner die, and has an upper cutting edge corresponding to the lower cutting edge on the inner edge of the lower end. The cutting blade die is fixed, and gaps corresponding to the minimum wall thickness of burrs due to crushing are provided between the upper and lower inner dies and between the upper and lower cutting blades, and gaps are provided between the upper and lower inner dies and between the upper and lower cutting blades. A deburring device for cast and forged products, characterized in that it is provided with a stopper for forming.
