Penetrate, be pressurized, cool down after make die casting machine upper mold backhaul.
(2) remove the mold that die casting finishes and be placed on it is shown in figure 15 throw on frame, two hand ends rise upper handle thrown to frame is thrown
Under, as shown in Figure 15 (a), under gravity, lower template 10 is instantly separable from and falls (by institute's cast aluminium alloy with centre circle 9
Bracket sleeve tube and 3 package power of endoporus core are larger, and such impact force is insufficient to allow the box-like centre circle of valve 9 to follow and falls), it is same with this
When 3 claw type sprue aluminum strips also thrown and disconnected fallen (shown in Figure 15 (b)) with lower template and cast gate clout simultaneously.
(3) casting is taken
As shown in Figure 15 (c), discharging ring is first placed in die casting machine lower die holder, then will be placed with the cope plate of the box-like centre circle of valve
On the discharging ring, finally the mandril with pressing plate is inserted into four corresponding apertures of upper mold, starts die casting machine downlink and push mandril,
Mandril pushes cope plate, and cope plate and the box-like centre circle of valve containing casting is finally made to fall off from core fixing plate together, pinches valve conjunction
Formula centre circle and slightly percussion, the box-like centre circle of valve accuse separation, take out casting.
Portable compression mod is a kind of ignored form of expression to be easier in die-casting process, but its casting quality and be no less than
It is mechanical with cheap portable die casting to substitute expensive duralumin in this example for compression mod (high investment) casting made of standard die set
Processing, significantly reduces production cycle and cost, which can yet be regarded as one of medium and small castings production beneficial to option.
