Claims

[Scope of utility model registration request]

A drive rod that moves up and down by the driving force transmitted from the shaft end of the slide drive shaft that moves the slide up and down, a drive side member to which the vertical power is transmitted from this drive rod, and a drive side member that is connected to this drive side member via an equalizing shaft. In a knock-out device for a press machine, which includes connected driven-side members and a knock-out pin that protrudes a molded product by vertical movement of these driving-side members and driven-side members, a first , the piston rods of two hydraulic cylinders are connected, and these first and second hydraulic cylinders each have a first chamber and a second chamber partitioned by a piston, and a first chamber of the first hydraulic cylinder and a second chamber of the second hydraulic cylinder are connected. A knockout device for a press machine, characterized in that the two chambers are connected by piping, and the second chamber of the first hydraulic cylinder and the first chamber of the second hydraulic cylinder are connected by piping.
