Abstract
The invention relates to a die mold comprising an upper mold unit, a lower mold unit and a slide block unit, wherein the upper mold unit is provided with an upper mold cavity unit, and the lower mold unit is provided with a lower mold cavity unit; the upper mold cavity unit cooperates with the lower mold cavity unit; the slide block unit is arranged in the space formed by the cooperation of the upper mold cavity unit and the lower mold cavity unit; the bottom of the slide block unit is provided with a material inlet; the die mold also comprises an oil hydraulic slide block drawing device used for drawing out the slide block unit; and three side surfaces of the slide block unit are respectively provided with a unilateral angle of 2 degrees. The scheme of the invention comprises the tunnel-type material feeding structure on the bottom of the slide block unit of the die mold and the oil hydraulic slide block drawing device; the material inlet is arranged in the positions beneficial to filling and forming of the casting by utilizing the slide block unit; and gas in the space fills a lot of space obtaining the cavity by the substitution of the raw material, thereby overcoming many defects in form filling and die casting.
Description
Technical field
The present invention relates to a kind of die casting, refer in particular to a kind of die casting of slider bottom charging, belong to the die casting technical field.
Background technology
Compression casting belongs to hot forming metal manufacture field, the structural design of die casting is bigger to die casting production influence, particularly the correct setting of running channel and cast gate directly influences the shaping of product and the quality of product with design, the design of correct mould structure and die casting running channel not only improves the qualification rate of foundry goods, reduce foundry returns, can also prolong the life-span of mould.Present die cast product is more to large-scale, complicated, accurate development, this just proposes higher requirement to the structural design of die casting and runner and cast gate design, sometimes often be because the design of mould structure and die casting running channel is provided with incorrect, cause foundry goods to be shaped and shaping fraction defective extra-high-speed, in the time can not passing through other die casting parametric compensation, have to be with the die casting condition of the limit, extrusion process and other numerous processing technology of increase remove bad influence, it still is undesirable having increased many man power and material's effects often, the mould premature failure, and the die casting cost increases.
Summary of the invention
The present invention seeks to have proposed a kind of die casting of slider bottom charging in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution used in the present invention is: a kind of die casting comprises mold unit, bed die unit, slide unit; Described mold unit is provided with unit, a patrix shape chamber; Described bed die unit is provided with unit, a counterdie shape chamber; Unit, described patrix shape chamber matches with unit, counterdie shape chamber; Described slide unit is arranged on unit, described patrix shape chamber and matches with unit, counterdie shape chamber in the space that forms; The bottom of described slide unit is provided with charging aperture.
Preferably, described die casting comprises that also oil pressure takes out slide block device, is used for extracting out slide unit.
Preferably, there are the angles of monolateral 2 degree described slide unit three sides.
Die casting of the present invention, the structure and the oil hydraulic cylinder that comprise the submarine charging of die casting slide unit bottom are taken out slide block device, thus, die-cast product is offered at die casting cast gate place just more more options, make the mould design help the shaping of die-cast product more, improve the interior external quality of product.Particularly to a little complexity and special die casting, surfaces externally and internally is irregular, intermediate shape is very complicated, distribution path is wide or the dead angle is numerous, make the gate land liquid material with simple several surfaces and be difficult to each corner in the smooth filling die cavity, the charging aperture of hiding by setting in the mould, utilize slide block that charging aperture is provided with and be beneficial to foundry goods filling and shaping everywhere, make filling with the entrance and exit type fluidised form, in a large number displace the space of cavity with the gas in the space is filled by raw material, the many defectives in shape and the die casting are filled in solution.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1 is the assembled sectional view of feeding structure of the die casting of prior art;
Fig. 2 is the assembled sectional view of the bottom feed structure of die casting of the present invention;
Fig. 3 is under the die casting closure state of the present invention, the closed cutaway view that forms the passage of hiding of slide unit;
Fig. 4 is under the die casting folding condition of the present invention, after the charging aperture of hiding after slide unit skids off exposes, and the cutaway view that product stripping takes out.
The specific embodiment
The die casting of prior art as shown in Figure 1, include one group of mold unit 1, one group of bed die unit 2, one group of upper cavity unit 3 that forms cavity, one group of lower mode cavity unit 4 that forms cavity, other member of above-mentioned main member and omission explanation is formed structure and interblock space kenel, the space 6 of shaping die casting, feeding-passage 7 and charging aperture 8.During casting forming, liquid material sealing foundry goods D portion 9 charging oral areas, formation can't be discharged the cavity space D portion 9 of gas, and tiny muscle position D portion 9 is shaped and can only fills with the pressure current form, and the effect of shaping is bad.
Die casting of the present invention as shown in Figure 2, include one group of mold unit 10, one group of bed die unit 20, one group of upper cavity unit 30 that forms cavity, one group of lower mode cavity unit 40 that forms cavity, one group of slide unit 50, take out slide block device (omitting explanation) with oil pressure, other member of above-mentioned main member and omission explanation is formed structure and interblock space kenel, shaping die casting space 60, feeding-passage 70 and the charging aperture 80 that is arranged on the bottom of described slide unit, during casting forming, the throat-fed that liquid material is forming, the liquid material fluidised form transfers to along tiny muscle position D portion 90 carries out the entrance and exit type filling, tiny muscle position D portion 90 forms open filling can the road, and tiny muscle position D portion 90 gases are easily discharged, shaping respond well.
As Fig. 3, the cutaway view under the die casting closure/folding condition of the present invention shown in Figure 4; Implement the structure of die casting charging of the present invention, the duty of feeding structure is described, the angle of 2 degree is all arranged at the slide unit bottom, so that the demoulding, particularly anti-limited slip block be heated with the shape chamber between produce card mutually, exhaustion plate unit 100 gas in the D portion 90 that is used for draining among the figure; Oil hydraulic cylinder assembly 110 promptly is that oil pressure is taken out slide block device, is used for extracting out slide unit 50.
Below only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the present invention, all drop within the rights protection scope of the present invention.
