The utility model discloses a curved arc core pulling mechanism for injection mould, which comprises a fixed die, a moving die, an oil cylinder, an oil cylinder connecting block, a connecting shaft, a sliding seat, an arc guide rail, an arc core pulling block and a wedge block; the oil cylinder connecting block is fixed on the side wall of the dynamic die, and the cylinder block is hinged on the oil cylinder connecting block, and the oil cylinder is alive. The end of the plug rod is connected with the outer end of the connecting shaft. The inner end of the connecting shaft is articulated at the outer end of the sliding seat and the outer end of the sliding seat is close to the top of the wedge block. The inner end of the sliding seat is connected with the outer end of the arc core puller. The sliding seat is sliding on the arc guide rail. The arc guide rail is fixed in the moving die, and the inner end of the arc core puller extends into the cavity. Because the cylinder piston rod of the utility model extracts the arc core-pulling rod outward through the slide seat, the arc core-pulling rod conforms to the product arc trajectory along the arc guide rail, so that the arc core-pulling rod is completely pulled out of the cavity, and finally the product is ejected from the ejector pin, and then the product is taken out, which has the advantages of stable and reliable movement.
