Zusammenfassung:	The utility model discloses a mould with an injection redundancy cavity. The mould with the injection redundancy cavity is composed of an upper mould body (3) and a lower mould body (6), and a concave cavity of the lower mould body (6) is a lower mould cavity (8). The mould with the injection redundancy cavity is characterized in that the upper mould body is provided with a wedge-shaped positioning upper plane and a plane seal mould plane, the inner side of a lower mould wedge-shaped positioning device (10) is provided with continuous rows of bean-point-shaped remaining material storage cavities (9), the remaining material storage cavities (9) are located on the upper plane of the lower mould body (6) and are communicated with mould cavity bodies through overflowing channels (11), and the remaining material storage cavities (9) are independent and disconnected. Due to the fact that the remaining material storage cavities are pre-reserved at the edge of the mould, excess foaming materials flow into the pre-res
