But describe die casting according to the vacuum pressure in the Real-Time Monitoring internal cavity of the embodiment of the invention in detail below with reference to accompanying drawing.
As shown in Fig. 1 to Fig. 3, but according to the die casting of the vacuum pressure in the Real-Time Monitoring internal cavity of the embodiment of the invention, comprising: dynamic model frame 1, moving lining mould 2, quiet framed 3, quiet lining mould 4, shot sleeve 5, drift 6, air bleeding valve 7 and construction bolt 8.
Particularly, air bleeding valve 7 tops are provided with discharge duct 9, and shot sleeve 5 front ends are provided with pouring slot 10.Moving lining mould 2 is arranged on the dynamic model frame 1, and quiet lining mould 4 is arranged on quiet framed 3.Moving lining mould 2 limits internal cavity with quiet lining mould 4, comprises sprue 11, cross gate 12, die cavity 13, ingate 14, overflow launder 15 and air discharge duct 16.Dynamic model frame 1 is provided with guide pin bushing 17, plays guiding function when die sinking, mold closing.
The present embodiment is provided with an arc transition polyline shaped groove 18 and a dihedral transition polyline shaped groove 19 at moving lining mould 2, and groove 18 and 19 is by quiet lining mould 4 sealings.The first end of groove 18 (upper end of groove 18 as shown in fig. 1) is communicated with overflow launder 15, and the first end of groove 19 (lower end of groove 19 as shown in fig. 1) is communicated with cross gate 12, and groove 18 and the second end of 19 are provided with measured hole 21.Measured hole 21 is communicated with the vacuum transducer (not shown) that is used for measuring the vacuum pressure in the described internal cavity.
But the die casting according to the vacuum pressure in the Real-Time Monitoring internal cavity of the embodiment of the invention, in the practical vacuum press casting procedure, after molten metal enters groove 18 and 19, because groove 18 and 19 is configured to polyline shaped, molten metal is in groove 18 and 19 interior flow process, temperature reduces gradually, flowing velocity reduces gradually, before reaching measured hole 21 positions that communicate with vacuum transducer, can solidify, thereby in the situation that do not stop up measured hole 21, the vacuum pressure of Real-Time Monitoring die casting internal cavity.
According to an example of the present invention, groove 18 and 19 first end can directly be communicated with described internal cavity.Advantageously, groove 18 and 19 first end are communicated with by transition groove 20 with described internal cavity.As shown in Figure 3, transition groove 20 is stepped along its depth direction (namely such as the above-below direction among Fig. 3).Thus, can further slow down the flowing velocity that molten metal enters groove 18 and 19 in press casting procedure.
Certainly, only show the concrete structure of two kinds of polyline shaped grooves 18 and 19 among Fig. 1, but the concrete structure of groove not only is confined to this.Such as, can also be the polyline shaped groove that dihedral transition and arc transition are mixed.
Further, the polyline shaped groove is N.Described N polyline shaped groove respectively with die cavity 13, sprue 11, cross gate 12, ingate 14, overflow launder 15 and the air discharge duct 16 of need monitoring vacuum pressure in the correspondingly adjacent setting of N cavity and communicate with each other.
That is to say, the polyline shaped groove can be one, to link to each other with in die cavity 13, sprue 11, cross gate 12, ingate 14, overflow launder 15 and the air discharge duct 16 any.The polyline shaped groove also can be two, with die cavity 13, sprue 11, cross gate 12, ingate 14, overflow launder 15 and air discharge duct 16 in any two link to each other correspondingly.By that analogy, each in die cavity 13, sprue 11, cross gate 12, ingate 14, overflow launder 15 and the air discharge duct 16 all can corresponding linking to each other with a polyline shaped groove.
In other words, can Real-Time Monitoring die cavity 13, any vacuum pressure in sprue 11, cross gate 12, ingate 14, overflow launder 15 and the air discharge duct 16, also can Real-Time Monitoring die cavity 13, certain several vacuum pressure in sprue 11, cross gate 12, ingate 14, overflow launder 15 and the air discharge duct 16, perhaps can Real-Time Monitoring die cavity 13, whole vacuum pressure in sprue 11, cross gate 12, ingate 14, overflow launder 15 and the air discharge duct 16.This is understandable for the person of ordinary skill of the art.
But the die casting according to the vacuum pressure in the Real-Time Monitoring internal cavity of the embodiment of the invention, in the practical vacuum press casting procedure, after molten metal enters groove, because recess configurations becomes polyline shaped, in the flow process, temperature reduces molten metal gradually in groove, flowing velocity reduces gradually, before reaching the measured hole position that communicates with vacuum transducer, can solidify, thereby in the situation that not stop up measured hole, the vacuum pressure of Real-Time Monitoring die casting internal cavity.
In the description of this specification, the description of reference term " embodiment ", " some embodiment ", " illustrative examples ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present invention or the example in conjunction with specific features, structure, material or the characteristics of this embodiment or example description.In this manual, the schematic statement of above-mentioned term not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or characteristics can be with suitable mode combinations in any one or more embodiment or example.
Although illustrated and described embodiments of the invention, those having ordinary skill in the art will appreciate that: in the situation that do not break away from principle of the present invention and aim can be carried out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is limited by claim and equivalent thereof.
