Abstract
The utility model discloses a vacuum die-casting mold which comprises a moving mold plate, a fixed mold plate, a moving mold, a fixed mold, a pressing chamber and a pressing rod, wherein the moving mold plate is internally provided with a sprue sleeve; the sprue sleeve is internally provided with a split-flow cone; the fixed mold is internally provided with a vacuumizing device; an overflow valve is further arranged between the vacuumizing device and the mold chamber; and a sealing ring is further arranged on the contacted surface of the fixed mold and the moving mold. As the die-casting mold adopts the vacuumizing device to vacuumize the mold chamber, and adopts the split-flow cone to split a metal flow, so that the mold filling process is more stable, and parts inside the mold chamber are more uniform and compact; by arranging the overflow valve, the mold filling pressure is verified; and by adopting the spherical split-flow cone, the mold filling resistance is reduced.
Description
Technical field
The utility model belongs to compression casting machinery equipment technical field, is specifically related to a kind of Vacuum Die Casting Mould.
Background technology
At present, when adopting extrusion process production structure complexity and required precision high product in the industrial production, the mould structure complexity, the assembly difficulty height, precision is difficult to guarantee, cavity filling process easily produces problems, makes die casting have problems such as the not up to standard and mechanical strength of crackle, shrinkage, air-tightness is relatively low easily.
The utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model provides a kind of Vacuum Die Casting Mould, solved that existing extrusion process exists easily crack, the problem of shrinkage, phenomenon such as air-tightness is not up to standard and mechanical strength is relatively low.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of Vacuum Die Casting Mould, comprise moving platen (1), solid plate (4), dynamic model (2), cover half (3), press chamber (10) and depression bar (6), be provided with sprue bush (7) in the described moving platen (1), be provided with branch flow cone (11) in the described sprue bush (7), be provided with vacuum extractor (8) in the described cover half (3), be provided with overflow valve (12) between described vacuum extractor (8) and the die cavity (9), also be provided with sealing ring (5) on the contact-making surface of described cover half (3) and dynamic model (2).
The diameter (d) of described pressure chamber (10) is less than the diameter (D) of sprue bush (7).
Described minute flow cone (11) the top be ball-shaped.
(3) beneficial effect
The utility model is compared to prior art, has following beneficial effect: because this compression mod adopts vacuum extractor that die cavity is vacuumized, and adopt to divide a flow cone that molten metal is shunted, and make cavity filling process milder, make various piece even compact more in the die cavity; Be provided with overflow valve, the check mold filling pressure; Adopt ball-shaped to divide flow cone, reduce to fill form-drag.
Description of drawings
Fig. 1 is the structural representation of the utility model Vacuum Die Casting Mould.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of Vacuum Die Casting Mould, comprise moving platen 1, solid plate 4, dynamic model 2, cover half 3, press chamber 10 and depression bar 6, be provided with sprue bush 7 in the described moving platen 1, be provided with branch flow cone 11 in the described sprue bush 7, be provided with vacuum extractor 8 in the described cover half 3, be provided with overflow valve 12 between described vacuum extractor 8 and the die cavity 9, also be provided with sealing ring 5 on the contact-making surface of described cover half 3 and dynamic model 2.The diameter d of described pressure chamber 10 is less than the diameter D of sprue bush 7.The top of described minute flow cone 11 is ball-shaped.
Because this compression mod adopts vacuum extractor that die cavity is vacuumized, and adopts and divides flow cone that molten metal is shunted, make cavity filling process milder, make various piece even compact more in the die cavity; Be provided with overflow valve, the check mold filling pressure; Adopt ball-shaped to divide flow cone, reduce to fill form-drag.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
