Description
Technical field
The present invention relates to and a kind of the casting and pouring mechanism that bridge-type multiple spot pours into a mould simultaneously is realized to heavy castings.
Background technology
Non-ferrous metal large-scale many frames group frame class (more than II class) foundry goods is generally applied to structure-bearing position, bear larger load, therefore good internal soundness is needed to ensure its mechanical property, when the casting Technology Design of this type of foundry goods, in order to ensure that foundry goods is without loose, crackle and less residual stress, considers during technological design that molten metal filling die cavity solidifies fast, steadily and simultaneously usually.Steadily to ensure quality of molten metal and gravity gradient feeding fast, solidify is ensure to shrink drag uniformity simultaneously, stress raisers are avoided to crack defect, reduce distortion, to ensure that foundry goods form and position tolerance reaches technical requirement, the present invention's design can meet above-mentioned requirements, has large thin-wall non-ferrous alloy casting powder injection molding to have realistic meaning to solution.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of for many frames group frame class large thin wall casting, and the casting mechanism that can realize fast, steadily and simultaneously solidify, is different from traditional large thin-wall non-ferrous alloy casting Design of Runner System.Casting mechanism of the present invention makes the flow process of molten metal in foundry goods die cavity obviously shorten, and adopts bottom multiple spot to introduce molten metal simultaneously.
For solving the problems of the technologies described above, the technical solution used in the present invention is: heavy castings bridge-type multiple spot is casting mechanism simultaneously, comprise vertical sprue, sprue is communicated with the horizontally disposed bottom cross gate being positioned at bottom, bottom cross gate is communicated with many and vertically sets up it rises liquid passage, every bar rises liquid passage upper end and is communicated with a horizontally disposed liquid stream unit, and be parallel to each other between liquid stream unit and be all positioned at the top of bottom cross gate, molten metal injects foundry goods by liquid stream unit;
Further, described each liquid stream unit comprises being positioned at and rises liquid passage upper end and the horizontally disposed upper strata cross gate be communicated with it, to be communicated with and horizontally disposed multiple ingate with upper strata cross gate, and slag trap.
Further, slag trap is positioned at the end of upper strata cross gate, and with the end running channel axis perpendicular of upper strata cross gate.
Further, bottom cross gate is also provided with fibrous filter net with the connectivity part rising liquid passage.
The present invention starts with from large-scale many frames group frame class casting structure feature, for casting mechanism was from foundry goods surrounding introducing molten metal in the past, the molten metal brought flows long flow path, resistance greatly at die cavity, the features such as volume gas is serious, cause the shaping rear oxidation slag inclusion of foundry goods serious, feeding a casting is not enough.Core point of the present invention utilizes anti-gravity pouring mode, and the design philosophy of " simplifying; change greatly little ", adopt the pouring type of " horizontal watering adds bottom pour mold ", large-scale Mg alloy castings running gate system is decomposed into several less liquid stream unit, adopt the pouring type of antigravity by each liquid stream unit steadily fast, fill type to ensure the shaping of heavy castings and internal soundness with each liquid stream unit, decrease liquid flow point and to fall apart the degree of volume gas slag inclusion.And liquid stream comparatively before the design form of running gate system more steady, achieve the maximization of thin-section casting and the thin-walled property of heavy castings.

Detailed description of the invention
As shown in the figure, heavy castings bridge-type multiple spot of the present invention is casting mechanism simultaneously, comprise vertical sprue 1, sprue 1 is communicated with the horizontally disposed bottom cross gate 2 being positioned at bottom, bottom cross gate 2 is communicated with many and vertically sets up it rises liquid passage 4, every bar rises liquid passage 4 upper end and is communicated with a horizontally disposed liquid stream unit, and be parallel to each other between liquid stream unit and be all positioned at the top of bottom cross gate, molten metal injects foundry goods by liquid stream unit; The liquid stream unit realizing this function can adopt various structures form, the present embodiment provides a kind of version to be, described each liquid stream unit comprises being positioned at and rises liquid passage 4 upper end and the horizontally disposed upper strata cross gate 6 be communicated with it, to be communicated with and horizontally disposed multiple ingate 5 with upper strata cross gate, and slag trap 7.
Slag trap is for collecting slag, and it is positioned at the end of upper strata cross gate in this example, and with the end running channel axis perpendicular of upper strata cross gate.Further, bottom cross gate is also provided with fibrous filter net with the connectivity part rising liquid passage, this screen pack not only plays the effect of impurity screening, be arranged on herein, also indirectly serve the effect that liquid level rising regulates, although namely bottom cross gate is level, each passway rising liquid passage be communicated with bottom cross gate is also in same level, liquid levels in theory in bottom cross gate should rise to each simultaneously and rise in liquid passage, but there is dividing of distance because each rises liquid channel distance sprue, liquid level arrival rises liquid passage part and has trickle difference, therefore, certain resistance can be played by fibrous filter net and delay regulating action, make each liquid level risen in liquid passage final increase to keep simultaneously.
The casting process of the present embodiment is: molten metal enters bottom cross gate 2 by sprue 1, after being shunted by bottom cross gate 2, along with the rising of bottom cross gate molten metal height, rise liquid passage 4 through every bar and enter each liquid stream unit, upper strata cross gate 6 again through each liquid stream unit is shunted to each ingate 5, and molten metal is injected foundry goods.
The top of bottom cross gate is positioned at owing to rising liquid passage, bottom cross gate is again horizontally disposed, so, each rise the molten metal of liquid passage to enter and rise be basic synchronization, also just ensure that each liquid stream unit can obtain the injection of molten metal simultaneously, guarantee the quick, simultaneously of cast, in addition, the structure of this antigravity it also avoid dripping that the mode from top to bottom of molten metal produces and spatters, fill type to ensure the shaping of heavy castings and internal soundness with each liquid stream unit, decrease liquid flow point and to fall apart the degree of volume gas slag inclusion.And liquid stream comparatively before the design form of running gate system more steady, achieve the maximization of thin-section casting and the thin-walled property of heavy castings.
