PURPOSE: A dual injection device is provided to improve molding precision and to prevent molding failure by preventing a first molded product from flowing during the molding of a second lower mold while the position of a first molded product is fixed through a first slide core. CONSTITUTION: A dual injection device comprises an upper mold(10), a first lower mold and a second lower mold(20,30), and a slide core(40). The first lower mold and the second lower mold are gradually molded to the upper mold and are installed to inject a complex molded product. The slide core is molded with the upper mold and the lower mold and processes undercut. The slide core comprises a first slide core and a second slide core(42,44). The slide core is individually operated by a first cam and a second cam(52).
