Claims

[Scope of utility model registration request]

A molding die is fit into the upper surface of the die holding stand installed in the lower turret so as to be able to move up and down, and a die fitting recess is formed in which the space below the die serves as an oil chamber, and pressurized oil is supplied to the oil chamber. A port for supplying and discharging the oil is provided, a guide shaft that passes through a guide hole provided at the bottom of the oil chamber projects from the lower surface of the die, and a return spring that engages with the guide shaft and biases the die downward is provided. The die holding mechanism of the turret punch press.
