The feeding funnel 51 is installed on the upper mold assembly 52 to feed the injection molding material into the upper mold assembly 52. ​​The upper mold assembly 52 and the lower mold assembly 53 are installed on the injection molding frame 54 in an upper and lower distribution. An injection molding space for the zipper tape to pass through is formed between the upper mold assembly 52 and the lower mold assembly 53. A slag discharge mechanism 55 is provided at a position close to the injection molding space of the injection molding frame 54 to discharge the waste slag injected on the zipper tape. Through the setting of the slag discharge mechanism 55, on the one hand, it can effectively prevent the waste slag from adhering to the zipper tape, thereby improving the product quality of the zipper. On the other hand, the slag discharge mechanism 55 can reduce the damage of the waste slag to the internal parts of the injection molding device. At the same time, the slag discharge mechanism 55 can timely clean up the waste slag, ensure the stable operation of the injection molding device, and improve production efficiency.
