Specific implementation mode
It is further illustrated the present invention below by the mode of embodiment, but does not therefore limit the present invention to the reality
It applies among a range.
Fig. 1 shows that the product that the present embodiment die casting is cast, hole 15 can be in the die castings of the present embodiment
Direct cast form.The die casting of the present embodiment includes as shown in Figures 2 and 3 model frame 1, cover half core 3, dynamic model frame 2,
Moving-mould-core 4, cover half core 3 and moving-mould-core 4 are mutually interlocked, and cavity 5 is formed in cover half core 3 and moving-mould-core 4, and model frame 1 is coated on
Except cover half core 3, dynamic model frame 2 is coated on except moving-mould-core 4, and die casting further includes the oblique core 7 of cover half, and the oblique core 8 of dynamic model is fixed
Mould elastic component 9, dynamic model elastic component 10, cover half compressing member 11, dynamic model sliding block 12, the oblique core 7 of cover half pass through model frame 1 and cover half core
3 are inserted into cavity 5, and cover half elastic component 9 is between model frame 1 and cover half core 3 and is sleeved on the oblique core of cover half 7, cover half elasticity
The pop-up power of part 9 can extract cavity 5 out with the oblique core 7 of active and inactive mold, and cover half compressing member 11 compresses the oblique core of cover half 7.
The oblique core 8 of dynamic model passes through dynamic model frame 2 and moving-mould-core 4 to be inserted into cavity 5, and dynamic model elastic component 10 is located at 2 He of dynamic model frame
It between moving-mould-core 4 and is sleeved on the oblique core of dynamic model 8, the pop-up power of dynamic model elastic component 10 can drive the oblique 8 extraction type of core of dynamic model
Chamber 5, the oblique core of 12 tight dynamic model of dynamic model sliding block pressure 8.
In the present embodiment, it is cylinder that the oblique core 7 of cover half and the oblique core 8 of dynamic model, which are inserted into the part of cavity, to be formed
The hole 15 of cast article shown in Fig. 1.Since there are many die casting component of the present embodiment, opened up in die casting outer wall
Cored hole can make the structure of die casting become extremely complex, by the pop-up power band of cover half elastic component 9 and dynamic model elastic component 10
The oblique core 7 of active and inactive mold and oblique 8 core pulling of core of dynamic model can greatly simplify structure of cast die, and hole is completed in casting to convenient
15 forming.
For ease of pop-up power band oblique 7 core pulling of core of active and inactive mold of cover half elastic component 9, oblique 7 outer end of core of cover half has convex
Platform 6, the diameter of boss 6 are more than the diameter of cover half elastic component 9, and one end of cover half elastic component 9 is against boss 6, and the other end is against calmly
The outer wall of mold core 3.Similarly, oblique 8 core pulling of core of dynamic model is driven for ease of the pop-up power of dynamic model elastic component 10, outside the oblique core of dynamic model 8
End has a boss 6, and the diameter of boss 6 is more than the diameter of dynamic model elastic component 10, one end of dynamic model elastic component 10 against boss 6,
Outer wall of the other end against moving-mould-core 4.
Preferably integrally to compress die casting, die casting further includes pressing plate, and pressing plate includes 13 He of cover half pressing plate
Dynamic model pressing plate 14.It is provided with cover half pressing plate 13 except model frame 1, dynamic model pressing plate is provided with except the square iron 16 except dynamic model frame 2
14.Cover half pressing plate 13 compresses cover half compressing member 11, and cover half compressing member 11 compresses the oblique core 7 of cover half, and cover half elastic component 9 is at this time
Impaction state, cover half elastic component 9 tend to the oblique core 7 of cover half popping up die cavity 5.Dynamic model pressing plate 14 compresses square iron 16, square iron 16
Dynamic model frame 2 is compressed, dynamic model frame 2 compresses dynamic model sliding block 12, and dynamic model sliding block 12 compresses the oblique core 8 of dynamic model, at this time dynamic model elastic component 10
In impaction state, dynamic model elastic component 10 tends to the oblique core 8 of dynamic model popping up die cavity 5.
As an alternative, there is die sinking elastic component between model frame 1 and cover half pressing plate 13, die sinking elastic component is in figure
It is not shown, when die sinking, this die sinking elastic component can make to flick about 2 centimetres between model frame 1 and cover half pressing plate 13
Distance is more convenient the pop-up of the oblique core of cover half 7.
As shown in figure 4, a kind of release method of above-mentioned die casting, the release method include the following steps：
Step 111, after the completion of above-mentioned die casting shooting, pressurization, cover half core 3 and moving-mould-core 4 by die casting machine band
Start to mold under dynamic；
After step 222, cover half core 3 and moving-mould-core 4 mold, cover half pressing plate 13 is detached with model frame 1, and cover half pressing plate 13 will be determined
11 band of mould compressing member is opened, and dynamic model sliding block 12 is extracted out along dynamic model length direction；
Step 333, cover half elastic component 9 extract cavity 5 out with the oblique core 7 of active and inactive mold, and dynamic model elastic component 10 drives the oblique type of dynamic model
Core 8 extracts cavity 5 out, and so far die casting molds completely；
Step 444, cover half core 3 and moving-mould-core 4 continue to separate, and the oblique core 7 of cover half and the oblique core 8 of dynamic model are extracted out, and top is utilized
Needle 17 ejects product, is detached from cavity 5, then goes out product clip with hawkbill, be placed on tote cart.
The present embodiment is by the pop-up power of cover half elastic component and dynamic model elastic component with the oblique core of active and inactive mold and the oblique core of dynamic model
Core pulling enormously simplifies structure of cast die, to the convenient forming for completing two holes on product in casting.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that this is only
For example, protection scope of the present invention is to be defined by the appended claims.Those skilled in the art without departing substantially from
Under the premise of the principle and substance of the present invention, many changes and modifications may be made, but these change and
