The specific embodiment
As shown in the figure, the utility model heavy castings bridge-type multiple spot is poured into a mould Casting Mechanism simultaneously, comprise vertical sprue 1, sprue 1 is communicated with the horizontally disposed bottom cross gate 2 that is positioned at bottom, bottom cross gate 2 is communicated with many and vertically sets up and rise liquid passage 4 on it, every rises liquid passage 4 upper ends and is communicated with the top that is parallel to each other between a horizontally disposed liquid stream ，Ye Liu unit, unit and is all positioned at bottom cross gate, and molten metal flow unit injection foundry goods by liquid; The liquid stream unit of realizing this function can adopt various structures form, the present embodiment provides a kind of version to be, described each liquid stream unit comprises and is positioned at the horizontally disposed upper strata cross gate 6 that rises liquid passage 4 upper ends and be communicated with it, is communicated with upper strata cross gate and horizontally disposed a plurality of ingate 5, and slag trap 7.
Slag trap is used for collecting slag, and it is positioned at the end of upper strata cross gate in this example, and vertical with the end running channel axle center of upper strata cross gate.Further, bottom cross gate is also provided with fibrous filter net with the connectivity part that rises liquid passage, this screen pack not only plays the effect of impurity screening, be arranged on herein, also indirectly played the effect that liquid level rises and regulates, although bottom cross gate is level, each connection with bottom cross gate rises the passway of liquid passage also in same level, liquid levels in bottom cross gate should rise to each simultaneously and rises in liquid passage in theory, but because rising liquid channel distance sprue, each has dividing of distance, liquid level arrival rises liquid passage part and has trickle difference, therefore, can play the slow regulating action of certain resistance by fibrous filter net, make the final liquid level that each rises in liquid passage rise maintenance simultaneously.
The casting process of the present embodiment is: molten metal enters bottom cross gate 2 by sprue 1, after 2 shuntings of bottom cross gate, rising along with bottom cross gate molten metal height, through every, rise liquid passage 4 and enter each liquid stream unit, through the upper strata cross gate 6 of each liquid stream unit, shunt to each ingate 5 again, molten metal is injected to foundry goods.
Owing to rising liquid passage and be positioned at the top of bottom cross gate, bottom cross gate is again horizontally disposed, so, each rise liquid passage molten metal to enter and rise be basic synchronization, also just guarantee that each liquid stream unit can obtain the injection of molten metal simultaneously, this just guaranteed cast fast, simultaneously, in addition, dripping that the structure of this antigravity has also avoided that the mode from top to bottom of molten metal produces spattered, with moulding and the internal soundness that type guarantees heavy castings of filling of each liquid stream unit, reduced the degree of the loose volume of liquid flow point gas slag inclusion.And the design form of liquid stream running gate system is before more steady, has realized the maximization of thin-section casting and the thin-walled property of heavy castings.
