ABSTRACT:
A die-casting device at least includes a housing having a seat, a lower mold mechanism at the seat, an oil-pressured injection mechanism joined with a lower section of the lower mold mechanism, and a corresponding upper mold mechanism disposed at an upper section of the housing and driven by an oil-pressured mechanism for up-and-down movements; wherein, the lower mold mechanism is devised as a structure with an outwardly inclined angle. Thus, when adding a metal liquid to the die-casting device, the lower mold mechanism is first inclined outward, such that when the metal liquid is flowed in to a material reservoir of an injection mechanism, a flow speed of the metal liquid is reduced to avoid formation of the bubbles, thereby preventing finished die-casting products from containing bubbles and thus elevating product quality.
