Abstract:
A method for making a synthetic resin injection molded body that is gate-cut by die opening after injection molding by means of a pinpoint gate 9. A cavity 10 is filled with a molten resin, from a first sprue 6 that is provided coaxially with the injection direction of the molten resin, through a runner 7 that is provided in the perpendicular direction to the first sprue 6, via a pinpoint gate 9 that is formed on a tip part of a second sprue 8 that is provided horizontally to the injection direction of the molten resin, from a gate port 9a of the pinpoint gate 9 formed on a cavity plane that is in parallel with the die opening direction; after cooling, gate cutting is performed by means of die opening; and a molded body is taken out in an ejection step.
