nullThe adjustable hot chamber machine of flow in this programme，Including dynamic model、Cover half and crucible，Dynamic model and cover half form casting runner when matched moulds，Liquid chamber is offered in crucible，Molten metal bath and pressure chamber it is provided with in liquid chamber，Gooseneck passage is offered in pressure chamber、Gooseneck mouth and the wing passage making gooseneck passage communicate with liquid chamber，The side of gooseneck passage is provided with injection plunger，The opposite side of gooseneck passage communicates with gooseneck mouth，Injection plunger under press time wing passage can be closed，Cover half is attached by contiguous block with pressure chamber，Interface channel it is provided with in contiguous block，Gooseneck mouth is communicated with casting runner by interface channel，The longitudinally height of gooseneck mouth is more than the longitudinally height of the interface channel communicating place with gooseneck mouth，The longitudinally height of gooseneck mouth also greater than communicates the longitudinally height of the gooseneck passage at place with gooseneck mouth，Steel ball and stage clip it is provided with at gooseneck mouth，Steel ball is positioned at the side of gooseneck passage.
The principle of this programme is: before carrying out die casting, by dynamic model and cover half matched moulds, and in the liquid chamber of crucible, pile molten metal bath, molten metal bath flows in gooseneck passage from wing passage, when carrying out die casting, press under injection plunger and wing passage is sealed, now forming the chamber closed between gooseneck passage, gooseneck mouth, interface channel and casting runner, injection plunger is pressed down, and the molten metal bath being positioned at gooseneck passage will enter casting runner through gooseneck mouth, interface channel.
When injection plunger is depressed into diverse location, it is positioned at the molten metal bath of the gooseneck passage pressure to steel ball by difference, now stage clip and molten metal bath respectively from two ends to the different size of active force of steel ball, the area making a concerted effort to fit between regulation steel ball and gooseneck mouth of this active force, thus regulate molten metal bath and enter the uninterrupted at gooseneck mouth from gooseneck passage, and then reach to regulate the purpose of the uninterrupted that molten metal bath enters casting runner.
This programme is compared with traditional hot chamber machine, this programme can be by changing steel ball and the contact area of gooseneck mouth at gooseneck mouth, thus reach to change the purpose of molten metal bath Flow-rate adjustment, the flow of molten metal bath is adjusted by the hot chamber diecasting function therefore using this programme according to practical situation, thus reaches to improve the purpose of casting quality.
Preferred version one: based on scheme preferred, also include control circuit, control circuit includes that contact switch, contact switch are arranged on injection plunger, be provided with in liquid chamber when contact switch closes can produce heat add thermal resistance.When die casting, pressing under injection plunger, the contact switch that is positioned on injection plunger Guan Bi, be now placed in liquid chamber adds thermal resistance and will produce heat, and this heat can make molten metal bath have good mobility, thus improves the quality of foundry goods further.
Preferred version two: preferably one preferred, control circuit also includes the first controllable silicon, first silicon controlled anode is connected with the positive pole of external dc power, and the first silicon controlled negative electrode is connected with adding thermal resistance, and the first silicon controlled controls pole and is connected with contact switch.Under the effect of external dc power, first silicon controlled anode voltage is more than cathode voltage, when press contacts switch Guan Bi under injection plunger, contact switch controls one, pole control signal to the first silicon controlled, so that the first controlled silicon conducting, the heating resistance performance being connected with the first controllable silicon also produces heat.
Preferred version three: based on scheme preferred, the level height of molten metal bath is less than the level height of gooseneck mouth.The level height of molten metal bath, less than the level height of gooseneck mouth, can prevent when not carrying out die casting, and molten metal bath is entered in casting runner by gooseneck mouth.
Preferred version four: based on scheme preferred, crucible be formed around circular arc chamfering.Circular arc chamfering can effectively prevent the stress of crucible four peripheral end portion joint from concentrating, and improves the service life of crucible.
