Description
Technical field
The utility model relates to a kind of die casting die, belongs to die casting die field.
Background technology
The essence of compression casting is under High Pressure, makes liquid state or semi liquid state metal with higher speed filling die-casting die (die casting) die cavity, and obtains the method for foundry goods with solidifying at forming under the pressure.
Compared with other casting method, die casting has following three aspects: advantage: 1, good product quality, and casting dimension accuracy is high, is generally equivalent to 6 ~ 7 grades, even can reach 4 grades; Surface smoothness is good, is generally equivalent to 5 ~ 8 grades; Intensity and hardness are higher, and intensity generally improves 25 ~ 30% than sand casting, but percentage elongation reduces approximately 70%; Dimensionally stable, interchangeability is good; Can the thin-wall complicated foundry goods of die casting; For example, current zinc alloy diecasting minimum wall thickness (MINI W.) can reach 0.3mm; Aluminium alloy castings can reach 0.5mm; It is 0.7mm that minimum casts out aperture; Minimum pitch is 0.75mm; 2, production efficiency is high, and machine productivity is high, and for example average eight hours of the horizontal cold pneumatics casting machine of domestic J III 3 type can die casting 600～700 times, and average every eight hours of low profile thermal chamber die casting machine can die casting 3000 ~ 7000 times; The die-casting die life-span is long, one pair of die-casting die, and die casting clock alloy, the life-span can reach hundreds of thousands, even up to a million times; Easily realize mechanization and automation; 3, economic effect is good, because pressur casting size is accurate, and the table advantages such as floodlight is clean; Generally no longer carry out machining and directly use, or processing capacity is very little, so both improved using rate of metal, has reduced again a large amount of process equipments and man-hour; Foundry goods price is easy; Can adopt combination die casting with other metals or nonmetallic materials; While not only having saved assembler but also save metal.
Die casting is one of state-of-the-art metal forming process, is to realize few smear metal, and the effective way of chipless, applies very extensively, develops very fast; At present diecasting alloys are no longer confined to zinc, aluminium, magnesium and the copper of non-ferrous metal, and expand gradually and be used for die casting cast iron and steel-casting; The most of rigid pressure transmission means that adopts of pressure supply unit in die casting die at present, this kind of mode has certain damage to equipment in the time that pressure is larger, even build-up of pressure bar fracture when serious.
Summary of the invention
For the mode that adopts rigid pressure to transmit in current die casting die, there is the problem of potential safety hazard in the utility model, has designed a kind of die casting die.
The technical scheme in the invention for solving the technical problem is:
This die casting die comprises patrix matrix, spring shield, fairlead, upper mode slider, counterdie die cavity, plays mode slider, spring; Spring shield and fairlead are cylinder barrel shaped structure; spring shield is coaxial distribution with fairlead; the upper end face of spring shield and fairlead and patrix matrix are integral type structure; spring upper end is fixed in the projection of patrix matrix bottom center; spring lower end is fixed in the projection at center above mode slider; counterdie die cavity is cylinder hollow structure; fairlead internal diameter equates with counterdie die cavity external diameter; counterdie die cavity internal diameter equates with upper mode slider external diameter; play mode slider and formed by two sections of cylindrical structures, play mode slider epimere external diameter and equate with counterdie die cavity internal diameter.
There is projection in described patrix matrix bottom center, and described projection diameter equates with spring endoporus aperture.
There is projection at described upper mode slider end face center, and described projection diameter equates with spring endoporus aperture.
The utility model has the following advantages: 1. the utility model is novel unique, and in use procedure, pressure transmission adopts elasticity transfer mode, has played the self-protection effect of equipment in ensureing to transmit certain pressure; 2. material is cheap, and cost of manufacture is low, and application is wide.

In figure: patrix matrix 1, spring shield 2, fairlead 3, upper mode slider 4, counterdie die cavity 5, a mode slider 6, spring 7.
Detailed description of the invention
As shown in Figure 1, 2: a kind of die casting die, its structure comprises: patrix matrix 1, spring shield 2, fairlead 3, upper mode slider 4, counterdie die cavity 5, a mode slider 6, spring 7, spring shield 2 is cylinder barrel shaped structure with fairlead 3, spring shield 2 is coaxial distribution with fairlead 3, spring shield 2 is integral type structure with upper end face and the patrix matrix 1 of fairlead 3, spring 7 upper ends are fixed in the projection of patrix matrix 1 bottom center, spring 7 lower ends are fixed in the projection at center above mode slider 4, counterdie die cavity 5 is cylinder hollow structure, fairlead 3 internal diameters equate with counterdie die cavity 5 external diameters, counterdie die cavity 5 internal diameters equate with upper mode slider 4 external diameters, playing mode slider 6 is made up of two sections of cylindrical structures, playing mode slider 6 epimere external diameters equates with counterdie die cavity 5 internal diameters, there is projection in patrix matrix 1 bottom center, and described projection diameter equates with spring 7 endoporus apertures, there is projection at upper mode slider 4 end face centers, and described projection diameter equates with spring 7 endoporus apertures.
The described die casting die of the present embodiment; when use; molten metal liquid injects in counterdie die cavity 5; now patrix matrix 1 is moved down; in folding process, upper mode slider 4 enters in counterdie die cavity 5 and molten metal is pressurizeed; after moulding to be cooled, will on patrix matrix 1, move unloading, after upper mode slider 4 shifts out counterdie die cavity 5, move and make the part of moulding become flexible the demoulding rising on mode slider 6.
Above-described embodiment is the preferred scheme of one just, obvious, and this embodiment can do other and change, as: counterdie die cavity 5 inner hole sections adopt other required forms, and the corresponding change of the cross sectional shape of upper mode slider 4 and a mode slider 6.
Though the scheme after above-mentioned change is superior not as the present embodiment, is obviously better than also prior art.
