PURPOSE:To inspect easily accuracy of a die after using at high accuracy, by providing a concave reference part on the side of a block for die, and working the bottom face and die face by a supporting member and a surface plate attached to the reference part and leaving the reference face as it is. CONSTITUTION:In casting a block 11 for die, streaky grooves 13 are formed on the sides 12 and worked at sufficient accuracy to form reference faces 14, 15. Supporting members 16 having sufficient accuracy are inserted into the grooves 13, and conformed to the faces 14, 15. The supporting members 16 are placed on a support 18 having sufficient accuracy and set on a surface plate 17. A die bottom plate 19 is worked on the block 11 for die to make it parallel to the face of the surface plate, and a die face 20 is worked basing on the faces 14, 15 to form a die 21. the reference faces 14, 15 are left on the die 21. When inspecting the accuracy of the die 21 after using, the supporting members 16 are inserted into the grooves 13 and the supporting members 16 are placed on the supports 18 on the surface plate 17. By this way, inspection of accuracy of the die face 20 can be performed easily and at high accuracy. |
