といった問題を有していた。[0003] These casting burrs are generally removed by the shearing force of a punch fixed to a trim mold. However, with conventional devices, the punching speed of the punch is not sufficient, and thus the burrs are uniformly removed. There has been a problem that it cannot be removed and remains on the inner surface of the product, or a casting burr adheres to the tip of the punch.

なってしまうといった問題が派生する。To solve such a problem, Japanese Patent Laid-Open Publication No.
In the apparatus disclosed in Japanese Patent No. 5151, the punch member is lowered at a low pressure up to the position where the casting burr is formed, and at the punching stage of the casting burr, the punch member is switched to a high pressure drop to remove the casting burr accurately. However, for this purpose, there arises a problem that the apparatus becomes complicated and expensive in that the punch cylinder must be accurately controlled using a hydraulic control apparatus.

The lower surface of the pressing plate 6 has cylinder bores a and jackets b and c at respective positions. Correspondingly, a support rod 7 for supporting the bore punch 8 and support rods 10 and 15 for supporting the punch blocks 11 and 16 are integrally provided vertically.
