Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
See Fig. 1, according to an aspect of the present invention, the invention provides a kind of self-locking material structure of mould, comprise the depressed part 6 be arranged on the mold of mould, the bottom of depressed part 6 comprises the first gas outlet and second gas outlet of this mould, first gas outlet place and the second gas outlet place are respectively arranged with the first switch electrode 1 and the second switch electrode 2 of more than the lower surface being positioned at depressed part 6, first switch electrode 1 is all connected with cold-chamber die casting machine master control system with second switch electrode 2, with make when the metal liquid in mould enter depressed part 6 first switch electrode 1 and second switch electrode 2 are electrically connected and short circuit time, cold-chamber die casting machine master control system receives this short-circuit signal and the feeding system 7 controlling mould stops mould material feeding.
In present embodiment, self-locking material structure arranges depressed part 6 and (is generally the form of rising head on mold, but the present invention is not limited thereto), and be provided with the first gas outlet and the second gas outlet in the bottom of depressed part 6, first gas outlet and the second gas outlet are installed the first switch electrode 1 and second switch electrode 2, and the first switch electrode 1 is connected with the master control system of second switch electrode 2 respectively at cold-chamber die casting machine, as shown in Figure 2, when the excessive generation flash of the metal liquid in mould, metal liquid enters depressed part 6 and contacts with second switch electrode 2 with the first switch electrode 1 simultaneously, because metal liquid has electric conductivity, therefore the first switch electrode 1 and second switch electrode 2 are electrically connected, the connecting circuit of electrode and cold-chamber die casting machine master control system is short-circuited, after cold-chamber die casting machine master control system receives short circuit signal, the feeding system 7 controlling mould stops mould material feeding, effectively prevent the race material phenomenon of mould from occurring.
Wherein, feeding system 7 is the metal liquids after injecting melting when die-casting forming die works in mould, in order to make in feeder process, it is smooth and easy when metal liquid enters mould inside from charging aperture, and it is adjustable at mould inside flowing forming process medium velocity, preferably, feeding system 7 is metal liquid pressure charging system.Such metal liquid just can obtain suitable speed and inject mould inside, one-step shaping of going forward side by side under the pressurization of metal liquid pressure charging system.
In the above-described embodiment, first switch electrode 1 and second switch electrode 2 must have electric conductivity, can form a closed short circuit current after the two contacts with metal liquid, cold-chamber die casting machine after receiving this short-circuit signal in time control feeding system 7 stop feed.Same, the temperature of different metallic articles under liquid condition is different, may be used for make the mould being provided with this self-locking material structure producing different metal goods, therefore preferably using the material of refractory metal material as the first switch electrode 1 and second switch electrode 2.
First switch electrode 1 and second switch electrode 2 are major parts that self-locking material structure forms short-circuit signal, in order to ensure that the two keeps normal work in operation, preferably, the periphery of the first switch electrode 1 and second switch electrode 2 all at least comprises three weeks protective layers, within three weeks, protective layer comprises first week adiabatic packing 3, and insulation packing 3 causes the electrode signal of the first switch electrode 1 and second switch electrode 2 to lose efficacy for preventing high temperature injury; Second week insulating ceramics 4, insulating ceramics 4 is for solving Insulation Problems, and anti-stop signal is disorderly; 3rd week adiabatic packing 5, adiabatic packing 5 can protect the first switch electrode 1 and second switch electrode 2 further, more effectively prevents high temperature injury from causing electrode signal to lose efficacy.
According to another aspect of the present invention, present invention also offers a kind of die-casting forming die, this die-casting forming die comprises the self-locking material structure of feed unit, die cast unit and above-mentioned mould; Wherein, feed unit can drive metal liquid to be entered die cast unit by cast gate, and the self-locking material structure of mould is positioned on the mold of die cast unit.Like this, when mould occurs to run material, metal liquid in mould and the first switch electrode 1 in self-locking material structure contact with second switch electrode 2 and form short circuit current, after receiving short circuit signal by cold-chamber die casting machine master control system again, the feeding system 7 controlling mould stops mould material feeding, prevents the continuation of running material phenomenon to occur.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but; the present invention is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
