description The utility model relates to an injection mould with a shoulder lapping type sprue trimming device. The injection mould comprises a cutter bush, a sprue cutter and an air cylinder, wherein the cutter bush is mounted on the mould and under a sprue; the sprue cutter is mounted in the cutter bush; a cutter opening in the upper end of the sprue cutter is matched with a product spure in the mould; a T-shaped cutter base is mounted at the lower end of the sprue cutter; the lower surface of the T-shaped cutter base is a horizontally tilted slope which is in contact with a wedge-shaped transmission rod; one wedge-shaped contacted end of the wedge-shaped transmission rod is matched with the slope, and the other end of the wedge-shaped transmission rod is connected to the air cylinder. By virtue of the injection mould with the shoulder lapping type sprue trimming device, a product and a runner are cut off by the sprue cutter while plastic is not cured after the injection molding and pressure maintaining of the product
