Abstract
The invention relates to a high-pressure casting die and particularly relates to an air exhausting method of the high-pressure casting die and the die. An air exhausting hole is formed in front of a cinder ladle and an air exhausting groove is arranged between the cinder ladle and the air exhausting hole. With the adoption of the air exhausting method and the casting die disclosed by the invention, the density of a product is improved and the product strength is enhanced; and the defects of air holes, cold marks, looseness or flow marks and the like can be obviously improved, and the production efficiency and the product yield can be obviously improved.
Description
Technical field
The present invention relates to the high-pressure casting mould, particularly a kind of method for exhausting of high-pressure casting mould and mould.
Background technology
In design during die casting, similar annular or middle hollow product need to bump in the centre and wear the position cinder ladle is set, and will run into so the such problem of exhaust problem.Not smooth because of exhaust, often can produce pore, cold line, loose or current mark.Therefore can cause the reduction of product compactness, product strength decline, percent defective to increase.
Summary of the invention
The object of the present invention is to provide a kind of method for exhausting and mould of high-pressure casting mould, it mainly solves the existing technical problem of above-mentioned prior art, adopt method for exhausting of the present invention and die casting can not only improve compactness, the reinforcement product strength of its product, and the defectives such as pore, cold line, loose or current mark can obviously improve, and production efficiency and product percent of pass will significantly promote.
The present invention solves the problems of the technologies described above the technical scheme that adopts.
A kind of method for exhausting of high-pressure casting mould is characterized in that: it is to open a steam vent in cinder ladle the place ahead, and air drain begins to rehearse in the middle of cinder ladle and steam vent.
The method for exhausting of described high-pressure casting mould is characterized in that: described steam vent diameter is 16mm.
The method for exhausting of described high-pressure casting mould is characterized in that: described steam vent is opened on cover half.
A kind of high-pressure casting mould can be realized aforesaid method, it is characterized in that: it is made of dynamic model and cover half; Wherein: the steam vent that arranges on the described cover half directly penetrates the cover half die, opens under oblique on the mould bases of die bottom again; Open the dark blind hole of 5-8mm on the described dynamic model.
Described high-pressure casting mould is characterized in that: the angle in oblique lower hole of opening is 225 ° or 315 ° on the described mould bases.
A kind of method for exhausting of aforesaid high-pressure casting mould is characterized in that: this method for exhausting is used for the die casting slide block place pore that begins to rehearse, and it is to open cinder ladle in the slide block slot position, opens like this steam vent of a diameter 16mm in the position of air discharge duct.
Compared with prior art, the invention has the beneficial effects as follows: adopt the die casting of method for exhausting of the present invention can not only improve its product compactness, strengthen product strength, and the defectives such as pore, cold line, loose or current mark can obviously be improved.Production efficiency and product percent of pass will significantly promote.

The specific embodiment
The invention discloses a kind of method for exhausting of high-pressure casting mould, it is to open a steam vent in cinder ladle the place ahead, and air drain begins to rehearse in the middle of cinder ladle and steam vent.Described steam vent diameter is preferably and is 16mm, and this steam vent diameter can be greater than 16mm, but is difficult for too greatly, preferably is no more than 30mm.As a kind of optimal way, described steam vent is opened on cover half.
Further introduce the present invention below in conjunction with drawings and Examples.
Embodiment 1
A kind of high-pressure casting mould can be realized method of the present invention, and it is made of dynamic model and cover half.
Wherein: as shown in Figure 1, 2, the upper steam vent 11 that arranges of described cover half (having die cavity 14) directly penetrates cover half die 12, opens under oblique on the mould bases 13 of die 12 bottoms again.
As shown in Figure 3, open the dark blind hole of 5-8mm on the described dynamic model, this structure mainly is to allow a part of aluminium bits be parked in the blind hole when exhaust, during spraying the aluminium bits is blown away from blind hole.So just avoid the aluminium bits to block steam vent.For fear of interfering with cooling water channel, during simultaneously convenient spraying the aluminium bits are blown away, therefore blind hole is can not Kai Detai dark.
During use, air drain 2 begins to rehearse in the middle of cinder ladle 3 and the steam vent.Steam vent size press shape of product and product size and decide, generally adopts diameter 16mm get final product, for the ease of processing, can suitably strengthen bore dia (preferably being no more than 30mm), when too large difficulty process.In order to prevent steam vent and the interference of dynamic model thimble, so steam vent 11 is opened on cover half.The angle in oblique lower hole of opening is 225 ° or 315 ° on the described mould bases, and the aluminium bits are discharged from the hole when opening such angle and be for easy to exhaust, and are convenient to processing.Can also open between 225 ° and 315 ° simultaneously, but will avoid sprue bush, guide pin bushing and die holding screw.Like this, the air at mold center position cinder ladle place just can pass through air discharge duct, and steam vent is discharged to air outside the mould.Thereby reach desirable exhaust effect.
See also Fig. 2, it is the structural representation of the embodiment of the invention 2 again.This method for exhausting is used for the die casting slide block place pore 11 that begins to rehearse, and it is to open cinder ladle 3 in slide block slot 4 positions, opens like this steam vent 11 of a diameter 16mm in the position of air discharge duct 2.
In sum, be preferred embodiment of the present invention only, be not to limit practical range of the present invention, i.e. all equivalences of doing according to the content of the present patent application claim change and modify, and all should be technology category of the present invention.
