Base plate of rubber punching sheet molding test piece

The utility model discloses a base plate of a rubber punching forming test piece, which comprises a base plate whole body, magnetic beads and a square frame, the base plate whole body is divided into two layers and comprises a rubber layer and a plastic layer, the plastic layer is arranged at the lower part of the rubber layer, the square frame is arranged at the upper part of the plastic layer, and the magnetic beads are arranged at the lower part of the plastic layer. By utilizing the characteristic that the hardness of rubber is lower than that of plastic and wood plates, when the cutter is in contact with the rubber layer, the loss of the cutting edge of the cutter is reduced. The base plate is integral, and local rubber in contact with the cutter is replaceable, so that the local rubber can be replaced without replacing the whole base plate when the local rubber is lost. A magnet is embedded in the lower portion of the base plate and attracts metal on the lower portion of the sheet punching machine, and
