イスク成形用金型。[Scope of Claim for Utility Model Registration] 1. A fixed side template, a movable side template, and a stamper installed on the plate surface of the movable side template, sandwiching the outer periphery of the stamper and attaching it to the outer periphery of the movable side template. It consists of a combination with an outer peripheral ring for cavity definition that also serves as a fixed stamper holder, and when the mold is closed, casting resin is injected into the cavity through a sprue that opens on the fixed side template to form a disk. In the mold, a cavity surface area that defines the outer periphery of the cavity on the inner peripheral surface side of the outer circumferential ring, and a guide surface area of a large-diameter stationary mold plate having a step from the cavity surface area are axially arranged. It has a stepped structure formed along the
A mold for forming a disk, characterized in that a stepped portion having a small diameter and a stepped portion having a large diameter is formed on the outer circumferential surface of the distal end of the stationary side template, respectively, to fit into each surface area of the outer circumferential ring. 2. In the disk molding mold described in claim 1 of the utility model registration claim, in the process of closing the mold, the stepped portion formed at the tip of the stationary side mold plate relative to the outer ring defines a cavity on the outer ring side. A mold for forming a disk, characterized in that dimensions are set so that a large diameter stepped portion fits into a guide area before fitting into a surface area.
