The invention relates to a die-casting mold applied to slide block core runner molding. Multiple core extracting structures are uniformly arranged around an upper mold core and a lower mold core between an upper mold base and a lower mold base; the core extracting structures comprise oil cylinders, slide block bases and slide block cores; the oil cylinders are fixed with the lower mold base through brackets; piston rods of the oil cylinders are connected with the slide block bases slidingly mounted between the upper mold base and the lower mold base; the slide block cores are mounted at the ends, near the upper mold core, of the slide block bases; the slide block cores, the upper mold core and the lower mold core form a mold cavity; multiple runners are vertically formed in mold cavity surfaces on one sides of the slide block cores; the runners are connected with pouring channels correspondingly arranged on the upper mold core; and the pouring channels are connected with a charging barrel mounted in the upper mold base. The die-casting mold has the characteristics of simple structure, high production efficiency, guarantee of the stand quality, reduction of the mold manufacturing cost and the like.
