In the present invention, the effect of baffle plate shows three aspects: one, float and be gathered in the first Room from making to be at the very start mingled with slag, less second Room that enters, thus intercepted and captured or enter in foundry goods by filter, play and extend filter service life or improve the effect of quality gradually; Its two, cushioned the shock of molten metal to filter while just starting to pour into a mould, play a protective role; The 3rd, due to the buffering of this baffle plate, more steady when molten metal flows through the second Room, the air capacity that makes to be involved in foundry goods greatly reduces, thereby improves casting quality.
Brief description of the drawings
Fig. 1 is the cutaway view of pouring basin according to an embodiment of the invention.
Detailed description of the invention
As shown in Figure 1, in the middle of the pouring basin of this embodiment, there is a dividing plate 1, the inner chamber of pouring basin is separated into the first Room I and the second Room II.Have opening 5 in the bottom of dividing plate 1, at opening, 5 places arrange baffle plate 2, to seal opening 5.The preparing material and treat that casting metal material is identical of baffle plate 2.
The present invention arranges this baffle plate can reach multiple technique effect.In casting, while just having started, baffle plate blocks molten metal, and molten metal is gathered at the first Room I, reaches certain liquid level, and the slag that is mingled with is wherein able to floatingly, and the effect of slag trap is played in the first Room, is mingled with slag and is collected in all the time in the first Room in whole casting cycle.After the of short duration time, baffle plate is melted by the high temperature of molten metal, and molten metal enters the second Room II, then enters casting die from the second Room.Through the buffering of baffle plate, comparatively mild when molten metal enters the second Room, can not be involved in air, thereby improve the quality of foundry goods.At pouring basin with filter 4 in the situation that, molten metal a little less than to the impulsive force meeting of filter many, thereby avoid damaging filter.
Need to consider the thickness of baffle plate 2, make the baffle plate can barrier metal liquid time enough, so that molten metal reaches and never can melt baffle plate 2 before enough liquid level and enter the second Room II in the first Room I.Here " enough liquid levels " refers to that, in molten metal starts to enter the blink of the second Room, the liquid level of the first Room remains at the position higher than opening 5 upper ends, like this, swims in first and indoor be mingled with slag and can not enter the second Room.
Baffle plate 2 can be to be integrated in pouring basin, for example by ceramic bonding in pouring basin.Can also be to be movably connected in opening 5 places.A kind of typical embodiment is, at opening 5 places of pouring basin diapire, a slot is set, and before casting, baffle plate 2 inserted in slot and leans against and on dividing plate 1, block opening 5.Like this, the pouring basin producer only need provide the aforementioned pouring basin with slot, uses producer need to make the baffle plate of suitable size by oneself according to self, all very convenient to the producer and user.More preferably, this slot can be opened in the place at pouring basin sidewall connecting partition 1 two ends, and this slot extends from top to bottom, can be with holding securely baffle plate 2.
