Abstract

The invention discloses an exhaust insert core structure of a double-color mold. The double-color mold is provided with a first injection female mold kernel, a second injection female mold kernel and a male mold kernel. An exhaust insert core is arranged in the male mold kernel. A first injection product is formed by the first injection female mold kernel and the male mold kernel. The first injection product is provided with a plurality of grids. The top end of the exhaust insert core is provided with bosses for correspondingly forming the grids. A cavity for forming a second injection product is formed in the second injection female mold kernel. The second injection product and the first injection product are combined. The combination surface of the second injection product and the exhaust insert core is an exhaust surface. When a male mold body and a female mold body are opened, since the bosses of the exhaust insert core are covered with the grids, the mold sticking force of the male mold body is increased, and the products are easily left in the male mold body. Meanwhile, due to the bosses at the top end of the exhaust insert core, the second injection product is not provided with structures stuffed in the grids of the first injection product, and accordingly the second injection product is uniform in thickness, and no shadow is produced by the appearance.
