Benefits of technology

This configuration effectively minimizes bubble formation in the die-casting products, enhancing their quality by ensuring a slower flow and reduced impact, thereby improving the strength and appearance of the final products.

Problems solved by technology

However, such phenomenon is quickly disappeared in water, whereas in a liquid having little fluidity and high cohesion, it is rather difficult to totally eliminate bubbles contained in the metal liquid that is filled into the mold chamber and takes formation in an extremely short period before the metal liquid solidifies.
Strength and appearance quality of such products are affected to reduce competitiveness and economical values of these products on market.

Embodiment Construction

[0014] To better understand structural characteristics and effects of the invention, detailed descriptions of a preferred embodiment shall be given with the accompanying drawings below.

[0015] Referring to FIG. 1, a die-casting device according to the invention at least comprises a housing 10 having a seat 11, a lower mold mechanism 20 at the seat 11, an oil-pressured injection mechanism 30 joined with a lower section of the lower mold mechanism 20, an upper mold mechanism 40 correspondingly disposed at an upper section of the housing 10 and driven by an oil-pressured mechanism for up-and-down movements. The invention is characterized that, the lower mold mechanism 20 is devised with an inclined angle θ at an outward direction as shown in FIG. 2, with the angle θ preferably ranging between 30 and 50 degrees.

[0016] Referring to FIG. 3, the lower mold mechanism 20 is located at an at a center area of an upper section of the seat 11, and is supported and located using symmetrical oil-...

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.

Description

BACKGROUND OF THE INVENTION [0001] (a) Field of the Invention [0002] The invention relates to a die-casting device, and more particularly, to a lower mold mechanism of an upright die-casting device. The lower mold mechanism is devised as being inclined with an appropriate angle, such that when a metal liquid is filled into a material reservoir at an upper section of an injection mechanism, a flow speed thereof is reduced to avoid formation of bubbles, thereby preventing finished die-casting products from containing bubbles and thus elevating product quality. [0003] (b) Description of the Prior Art [0004] A prior die-casting device comprises at least a lower mold mechanism at a seat of a machine body thereof. The lower mold mechanism has a lower section thereof joined with an oil-pressured injection mechanism, and the machine body has an upper section thereof provided with a corresponding upper mold mechanism driven by an oil-pressured mechanism for up-and-down movements. When the lo...
