金型装置。[Scope of Claim for Utility Model Registration] (1) In a mold device that punches the inner diameter of a punched material in the same step during the progressive feeding process for manufacturing a laminated core, the outer diameter punch attached to the upper die is , an inner diameter punch is concentrically built in, an inner diameter punch is concentrically built into an outer diameter punch die attached to the lower die, and the outer diameter punch is arranged so that the inner diameter punch is connected to the inner diameter punch die. A step is provided between the inner diameter punch and the inner diameter punch so that the inner diameter of the core is punched after being fitted, and then the outer diameter of the core is punched by being fitted with the outer diameter punch die. A holding means that has an upward force capable of resisting the punching force, has a lower end supported by a spring so as to be able to be lowered by the pressing force of the punch for punching the outside diameter, and holds the core from which the outside diameter has been punched out in the punched material. A mold device for manufacturing a laminated iron core, characterized in that the inside diameter punching die is provided with a passageway through which the punched inside diameter scraps fall and are discharged to the outside of the lower die. (2) The core holding means is a push-back means that returns the core punched by a one-step outer diameter punch into the punched hole of the punched material by an outer diameter die when the upper die is raised. A mold device for manufacturing a laminated iron core as described in scope (1). (3) The holding means for the iron core adjusts the level difference between the outer diameter punch and the inner diameter punch so that the outer diameter is half punched.
) A mold device for manufacturing a laminated iron core as described in item 2. (4) Claims in which the core holding means is provided with a portion on the outer periphery of the outer diameter punch that cannot be punched so that a part of the outer diameter of the punched core is connected to the punched material. A mold device for manufacturing a laminated iron core as described in paragraph (1).
