Description
Technical field
The utility model relates to a kind of magnesium alloy pouring system, particularly a kind of magnesium alloy sand casting ladder clearance type running gate system.
Background technology
Magnesium alloy is to be that base adds the alloy that other elements are formed with magnesium.Be characterized in: density is little, and the specific strength height is bigger than elastic modelling quantity, good heat dissipation, and shock absorbing is good, and the load-carrying ability that withstands shocks is bigger than magnesium alloy, and the corrosive nature of anti-organic matter and alkali is good.Main alloy element has magnesium, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium etc.Be mainly used in industrial departments such as Aeronautics and Astronautics, transportation, chemical industry, rocket.Be the lightest metal in practical metal, the proportion of magnesium approximately is 2/3 of magnesium, is 1/4 of iron.It is the lightest metal in the practical metal, high strength and high rigidity.
Magnesium alloy shrinks big when casting, easily oxidation, and it is fast to lower the temperature in the flow process, pushing off the slag difficulty in the cast, foundry goods is easy to generate loose, defectives such as secondary oxidation slag inclusion.Therefore it is fast to require the magnesium alloy pouring system to have poring rate, and the pushing off the slag ability is strong, flows steadily, helps the characteristics of consecutive solidification and feeding.
Traditional magnesium alloy pouring system adopts rising pouring clearance type running gate system more, one end of cross gate is connected the bottom of sprue, the other end of cross gate connects the bottom of ladder clearance type running channel, liquid magnesium alloy flows into cross gate from sprue, flow into ladder clearance type running channel from cross gate again, can guarantee the consecutive solidification of foundry goods.Because molten metal is entered by cross gate, make the drop of the upright tube in slit big, be easy to generate the secondary slag making, and the filtration facility in the running gate system can't be disposed the bits of generation up hill and dale, make cast(ing) surface form a large amount of dirt holes and make surface quality defective, serious meeting causes foundry goods to suppress the phenomenon of seepage.
The utility model content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of magnesium alloy sand casting ladder clearance type running gate system is provided, the generation of can avoid magnesium liquid eddy current, splashing, and have stronger skimming ability.
For solving above technical problem, a kind of magnesium alloy sand casting ladder clearance type running gate system of the present utility model, comprise cast gate, cast gate sprue and ladder clearance type running channel, also comprise first cross gate, second cross gate and the 3rd cross gate, described second cross gate is positioned at the top of described first cross gate and the 3rd cross gate, the bottom of described cast gate sprue links to each other with an end of first cross gate, the other end upward opening of described first cross gate and link to each other with an end of described second cross gate by second sprue, the other end of described second cross gate links to each other with an end of described the 3rd cross gate under shed and by the 3rd sprue, and the other end of described the 3rd cross gate links to each other with the bottom of described ladder clearance type running channel; Described second cross gate middle part is provided with the filter screen that liquid magnesium alloy is filtered, and the sectional area of described first cross gate, second cross gate or the 3rd cross gate is respectively greater than the sectional area of described cast gate sprue, second sprue or the 3rd sprue.
With respect to prior art, the utility model has been obtained following beneficial effect: during cast, liquid magnesium alloy flows to first cross gate along the cast gate sprue from the cast gate of eminence, because the sectional area of first cross gate is big, the flow velocity of liquid magnesium alloy slows down, and is easy to skimming; Liquid magnesium alloy enters second cross gate by second sprue then, because the sectional area of second cross gate is greater than second sprue, the flow velocity of liquid magnesium alloy in second cross gate is slower, makes the slag in the liquid magnesium alloy separate come-up easily, and filter screen can more effectively hinder slag; Then liquid magnesium alloy enters in the 3rd cross gate of below by the 3rd sprue, because the sectional area of the 3rd cross gate makes liquid magnesium alloy steadily fill type greater than the 3rd sprue; Last liquid magnesium alloy is entered in the ladder clearance type running channel by the 3rd cross gate, steadily rises with ladder clearance type running channel, because the sectional area of ladder clearance type running channel is very little, lighter scum silica frost floats to rising head on can be ceaselessly; This system has adopted three sections crooked cross gates that connect, and makes the magnesium liquid can smooth flow, not eddy generation, splashes and impact phenomenon.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, accompanying drawing only provides reference and explanation usefulness, and is non-in order to restriction the utility model.
Fig. 1 is the structural representation of the utility model magnesium alloy sand casting ladder clearance type running gate system.
Among the figure: 1. cast gate; 2. cast gate sprue; 3. first cross gate; 4. second sprue; 5. second cross gate; 6. the 3rd sprue; 7. the 3rd cross gate; 8. ladder clearance type running channel; 9. rising head; 10. dashpot; 11 filter screens.
The specific embodiment
As shown in Figure 1, magnesium alloy sand casting ladder clearance type running gate system of the present utility model comprises cast gate 1, cast gate sprue 2, first cross gate 3, second sprue 4, second cross gate 5, the 3rd sprue 6, the 3rd cross gate 7 and ladder clearance type running channel 8, second cross gate 5 is positioned at the top of first cross gate 3 and the 3rd cross gate 7, the bottom of cast gate sprue 2 links to each other with an end of first cross gate 3, the other end upward opening of first cross gate 3 and link to each other with an end of second cross gate 5 by second sprue 4, the other end of second cross gate 5 links to each other with an end of the 3rd cross gate 7 under shed and by the 3rd sprue 6, and the other end of the 3rd cross gate 7 links to each other with the bottom of ladder clearance type running channel 8; The sectional area that second cross gate, 5 middle parts are provided with filter screen 11, the first cross gates 3, second cross gate 5 or the 3rd cross gate 7 that liquid magnesium alloy is filtered is respectively greater than the sectional area of cast gate sprue 2, second sprue 4 or the 3rd sprue 6.First cross gate 3 is provided with dashpot 10 over against the bottom, position of cast gate sprue 2, and the bottom of ladder clearance type running channel 8 also is provided with dashpot.
During cast, liquid magnesium alloy flows to first cross gate 3 along cast gate sprue 2 from the cast gate 1 of eminence, because the sectional area of first cross gate 3 is big, the flow velocity of liquid magnesium alloy slows down, and is easy to skimming; Liquid magnesium alloy enters second cross gate 5 by second sprue 4 then, because the sectional area of second cross gate 5 is greater than second sprue 4, the flow velocity of liquid magnesium alloy in second cross gate 5 is slower, makes the slag in the liquid magnesium alloy separate come-up easily, and filter screen 11 can more effectively hinder slag; Then liquid magnesium alloy enters in the 3rd cross gate 7 of below by the 3rd sprue 6, because the sectional area of the 3rd cross gate 7 makes liquid magnesium alloy steadily fill type greater than the 3rd sprue 6; Last liquid magnesium alloy is entered in the ladder clearance type running channel 8 by the 3rd cross gate 7, steadily rises with ladder clearance type running channel, because the sectional area of ladder clearance type running channel is very little, lighter scum silica frost floats to rising head 9 on can be ceaselessly.
The above only is the preferable possible embodiments of the utility model, and is non-so limit to scope of patent protection of the present utility model.In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
