の射出成形機。[Scope of Claim for Utility Model Registration] (1) A method for injecting a prescribed resin material heated and fluidized in a heating cylinder through a nozzle at the tip of the heating cylinder and filling it into a product cavity of a prescribed mold. In the injection molding machine, the nozzle part is provided with a regulating member that changes the cross-sectional shape of the injection resin passage and regulates the resin flow part, and the resin passage part corresponding to the product cavity is arranged so that the resin passage part corresponds to the product cavity. An injection molding machine characterized in that a portion of the cavity with a larger amount of resin becomes a passage portion with a larger cross-sectional area. (2) The regulating member changes the cross-sectional outer peripheral shape of the injected resin passage of the nozzle part, and the outer peripheral part of the part of the product cavity where the amount of resin is smaller is inwardly recessed. An injection molding machine according to claim 1, which has been registered as a utility model. (3) The regulating member is disposed at the center of the injection resin passage of the nozzle part to regulate the flow of resin in the center, and the part of the product cavity where the amount of resin is smaller is the outer part. An injection molding machine according to claim 1, which has a protruding outer periphery.
