Then, with reference to Fig. 2, gate seal pin 24, center loaded pins 25 and local loaded pins 26 position relative to die cavity 22 is described.Fig. 2 is the top view that die cavity 22 is shown.As shown in Figure 2, die cavity 22 is expanded symmetrically in the x-direction and the z-direction centered by gate seal Xiao24He center loaded pins 25.In the example shown in Fig. 2, pressurized pin 26 is provided with 6 near the end of die cavity 22.
Then, with reference to Fig. 3 A ~ Fig. 3 D and Fig. 4, the filling action of filling motlten metal A from compression chamber 10 to die cavity 22 is described.Fig. 3 A ~ Fig. 3 D is the skeleton diagram of filling action.Fig. 4 is the figure of the change of the pressure reduction P3 of process from pressurized source 16 to die cavity 22 applied pressure P1, the pressure P 2 of aspirating die cavity 22 from vacuum plant 32 and these pressure P 1, P2 (hereinafter referred to as filling pressure reduction) illustrated along with the time.In addition, in the present embodiment, filling action is performed based on the elapsed time.Such as, the liquid level measuring motlten metal A in advance arrives the time of opening 23a, and performs filling action based on the time of this mensuration.
In filling action, first, as shown in Figure 3A, at moment t11, controller 33 makes valve 15 open.Then, controller 33 from pressurized source 16 via confined space from gas supplying passage 13 to compression chamber 10 supply inert gas.Thus, as shown in Figure 4, after moment t11, rise from pressurized source 16 to compression chamber 10 applied pressure P1.Therefore, as shown in Figure 4, fill pressure reduction P3 and rise, the liquid level of motlten metal A rises.
Then, as shown in Figure 3 B, arrive the opening 23a of die cavity 22 at moment t12 motlten metal A, controller 33 also continues from pressurized source 16 via the confined space supply inert gas of gas supplying passage 13 to compression chamber 10 afterwards.In addition, as shown in Figure 3 B, controller 33 relief valve 31 and die cavity 22 is communicated with vacuum tank 321.Thus, the gas in die cavity 22 is expelled to vacuum tank 321 via exhaust path 23b.In addition, motlten metal A reaches the situation of the opening 23a of die cavity 22, both can be detected by sensor, also can measure in advance and make liquid level arrive the time of opening 23a with authorized pressure, and manage with this time.
By the control shown in above-mentioned Fig. 3 B, as shown in Figure 4, also continue from pressurized source 16 to die cavity 22 applied pressure P1 after moment t12 to rise.But according to the shape of die cavity 22, the rate of climb of pressure P 1 is non-constant.In addition, by the control shown in above-mentioned Fig. 3 B, due to the discharge from die cavity 22 realized based on vacuum plant 32, decompression (vacuum) degree thus in mould increases.That is, as shown in Figure 4, reduce to die cavity 22 applied pressure P2 to negative direction.Due to these pressure P 1, P2, as shown in Figure 4, fill pressure reduction P3 to rise.
Then, as shown in Figure 3 C, when filling motlten metal A at moment t13 in die cavity 22, motlten metal A flows into the chilled iron 23c freezing solidly on the periphery being configured in die cavity 22, and infilling work completes.If motlten metal A solidifies at all chilled iron 23c, then controller 33 shutoff valve 31 and stop decompression.But be maintained constant pressure from the pressure of pressurized source 16, the motlten metal A in die cavity 22 solidifies at this pressure.In addition, now, push away gate seal pin 24 under and block opening 23a.Then, as shown in Figure 3 D, controller 33 makes valve 17 open and makes compression chamber 10 to atmosphere opening, and the liquid level of the motlten metal A in bar 18 is reduced.Now, controller 33 also can Xia Tui center loaded pins 25 and to pressurization in die cavity 22, raise this pressure further as shown in Figure 3 D.And, pressurized pin 26 also can be used to pressurize simultaneously.In addition, gate seal Xiao24He center loaded pins 25 also can be Construction integration, in this case, independent cylinder body is declined, and carries out cast gate close and pressurization with continuous action.After motlten metal A in die cavity 22 solidifies, flexible mould 21 is made to rise and take out product.
At this, in following method, motlten metal A becomes the spittle and invades in die cavity 22, crack, cold shut is produced in products formed, the method is: close with gate seal pin 24 die cavity 22 be depressurized, to pressurization in compression chamber 10, make motlten metal A rise to immediately below gate seal pin 24, open gate seal pin 24 flows in die cavity 22 by the pressure official post motlten metal A of pressurization and decompression.On the other hand, present embodiment is under the state that gate seal pin 24 is open, as described above, to the opening 23a being forced into motlten metal A arrival die cavity 22 in compression chamber 10, motlten metal A proceeds the pressurization in compression chamber 10 after arriving the opening 23a of die cavity 22, and, as shown in Figure 4, reduce pressure gradually in die cavity 22.Thereby, it is possible to filling pressure reduction P3 when making motlten metal flow into mould rises lentamente.Therefore, present embodiment can suppress the splashing of motlten metal A, and products formed can be suppressed to produce crack and cold shut.
In addition, in the present embodiment, the pressure in vacuum plant 32 and 10 pairs, compression chamber die cavity 22 is utilized to control.Therefore, with multiple compression chamber is set and compared with situation about controlling the pressure in die cavity 22, present embodiment can become simple structure.In addition, compared with situation about only being controlled by the pressure in 10 pairs, compression chamber die cavity 22, present embodiment can control the load that compression chamber 10 bears, and can ensure the air-tightness of compression chamber 10.For reference, Fig. 5 illustrates that the process along with the time in the comparative example simultaneously not using vacuum plant 32 is from pressurized source 16 to the change of the pressure reduction P3 of the pressure P 2 of die cavity 22 applied pressure P1, die cavity 22 and these pressure P 1, P2.When there is not the decompression of die cavity 22, carry out along with motlten metal A flow into die cavity 22 and fills, produce back pressure at remainder, this back pressure applies to filling final stage and is also become large further by compression, hinders motlten metal to the filling of final filling part.Therefore, if will eliminate this back pressure by means of only the pressurization of compression chamber, then as shown in Figure 5, must need to make plus-pressure P1 become large.But increase pressure in the closed container having 700 DEG C of high-temperature systems, this correspondingly needs to strengthen gas-tight seal portion to alleviate the countermeasure of heat load.That is, not only need encapsulant itself to be the material with heat resistance, also need to suppress the thermal expansion of seal member or the countermeasures of thermal deformation such as flange, such as, need to arrange cooling circuit etc. near sealing.In addition, not only used material expensive but also equipment complexity.Can address this is that in the present embodiment.
In addition, in the present embodiment, because the back pressure in die cavity 22 can be suppressed by vacuum plant 32, therefore, it is possible to improve the mobility of the motlten metal A in die cavity 22.
Be explained above working of an invention mode, but the present invention is not limited thereto, various change can be carried out in the scope of purport not departing from invention, add.
