The invention discloses a blow molding device capable of in-mold labeling of labels exceeding half a circle in a blow mold, comprising: a blow mold and a core base. At least one mold cavity is formed in the blow mold, and a core and a blow molding air passage are arranged on the core base. The blow mold comprises an upper blow mold and a lower blow mold, and lower blow mold cavities in one-to-one correspondence with the at least one mold cavity of the blow mold are formed in the lower blow mold. The upper blow mold comprises a pair of openable and closable upper blow mold halves, and upper blow mold half-cavities in one-to-one correspondence with the at least one mold cavity of the blow mold are respectively formed on the opening and closing surfaces of the pair of upper blow mold halves. When the pair of upper blow mold halves are closed, the upper blow mold half-cavities on the pair of upper blow mold halves are enclosed in one-to-one correspondence to form upper blow mold cavities. The invention also discloses a translational injection blow molding process for in-mold labeling, which is suitable for labeling labels exceeding half a circle, and is even easier for labeling labels less than half a circle.
