After the molding inner mold is filled with cooling water, the cooling water can flow out through the water outlet hole and along the inner side of the molded cable protective cover, thereby better reducing the temperature of the molding inner mold and the inner side temperature of the molded cable protective cover. In addition, the molded cable protective cover has been pre-cooled and the temperature difference between the cooling water flowing out through the water outlet hole and the molded cable protective cover is not large, which will not cause the cable protective cover to shrink.

[0023] In addition, by arranging an air cooling cylinder on the obliquely lower outer end side of the molding outer mold cylinder, when the cable protective sleeve is pulled outward after molding, the cable protective sleeve can be cooled again by annular blowing, thereby improving the cooling efficiency of the cable protective sleeve.

Since the water outlet hole 602 on the molding inner mold 6 is located at the upper end of the circular plane of the molding inner mold 6, after the molding inner mold 6 is filled with cooling water, it flows out through the water outlet hole 602 and along the inner side of the molded cable protective sleeve, thereby better reducing the temperature of the molded cable protective sleeve, and the molded cable protective sleeve has been pre-cooled and the temperature difference between the cooling water flowing out through the water outlet hole and the molded cable protective sleeve is not large, which will not cause the cable protective sleeve to shrink. When the cable protective sleeve is pulled outward after being formed, the cable protective sleeve is again cooled by an annular blowing through the air cooling cylinder 7, thereby improving the cooling efficiency of the cable protective sleeve.
