Claims

[Scope of Claim for Utility Model Registration] (1) A sprue bushing having a nozzle touch fitted to the nozzle tip of an injection machine at its rear end and having a fitting shape that allows the tip of the sprue bush to fit into the material receiving part of the molding machine. A nozzle touch sprue characterized by a structure in which the sprue bush is urged toward the injection machine side by a spring and held movably. (2) The nozzle touch sprue according to claim (1), wherein the tip of the sprue bush is formed with a spherical convex surface and the material receiving portion is formed with a spherical concave surface. (3) The nozzle touch sprue according to claim (1), wherein the tip of the sprue bush is formed into a spherical concave surface and the material receiving portion is formed into a spherical convex surface. (4) The tip of the sprue bush has a convex truncated surface,
The nozzle touch sprue according to claim (1) of the utility model registration, wherein the material receiving portion is formed into a truncated concave surface.
