The vacuum air extractor cushioning structure can prevent fluid from directly impacting a vacuum valve and can improve the protection effect of the vacuum valve. Meanwhile, the automobile die-casting part pouring channel system can be obtained on the basis of an air extraction channel impurity removing structure, and the advantages of reducing the bubble content in a product, and improving the quality of the product can be achieved.
Description
Technical field
The utility model relates to a kind of automobile die casting parts cast channel system, especially a kind of vacuum suction device buffer structure of automobile die casting parts cast channel system
Background technology
Automobile die casting parts are meant the general part that adopts the die casting mode to make of a type in the auto parts.All belong to this type component such as some engine attaching parts, chassis or vehicle body attaching parts.These parts are owing to the function of using, and internal soundness control requires tighter usually.
Existing a kind of automobile die casting parts cast channel system; By forming behind dynamic model and the quiet mould matched moulds; Comprise a plurality of part die cavities that are set up in parallel; Distribution is connected in a plurality of slag traps of part die cavity side, and a side of each part die cavity all is connected to a horizontal running channel through an ingate, and laterally the running channel middle part connects the sprue gate through main running channel.
In this existing cast channel system, lean on slag trap to collect unnecessary gas and impurity in the part die cavity.But owing to be gas to be squeezed in the slag trap,, cause and contain a large amount of pores in the part that makes, reduced product quality so still have a large amount of gas residue in part die cavity by the mode of forcing punching press.For the strict product of some internal soundnesses, be difficult to reach the requirement of product quality.
The utility model content
Deficiency to above-mentioned prior art; The utility model technical problem to be solved is; How to provide a kind of fluid of can avoiding directly to impact vacuum valve, improve the vacuum suction device buffer structure of the automobile die casting parts cast channel system of vacuum valve protection effect; A kind of automobile die casting parts cast channel system that obtains based on this vacuum air extractor buffer structure also is provided simultaneously, reaches and reduce air bubble content in the product, guarantee the requirement of product internal porosity, the effect of improving the quality of products.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of vacuum suction device buffer structure of automobile die casting parts cast channel system; It is characterized in that; Said vacuum suction device buffer structure is connected between vacuum suction device and main the bleeding; Comprise a first passage, a second channel and a third channel, the middle part of said first passage and vacuum suction device inlet vertical connection, an end vertical connection of an end of said second channel and first passage; One end of said third channel and the other end vertical connection of second channel, the other end of said third channel and the main vertical connection of bleeding.
Like this, can avoid fluid directly to impact vacuum valve, cause vacuum valve to be washed out, simultaneously in the fluid still remaining impurities also can directly not impact vacuum valve and result in blockage, further improve vacuum valve protection effect, improve the stability of a system.
Description of drawings
Fig. 1 is a kind of sketch map that has adopted a kind of automobile die casting parts cast channel system of the utility model structure.
The specific embodiment
Below in conjunction with a kind of a kind of automobile die casting parts cast channel system of the utility model structure and accompanying drawing of having adopted the structure and the advantage of the utility model are done further to specify.
During practical implementation.As shown in Figure 1; A kind of automobile die casting parts cast channel system, said cast channel system form after by dynamic model and quiet mould matched moulds, comprise a plurality of part die cavities 1 that are set up in parallel; Distribution is connected in a plurality of slag traps 2 of part die cavity side; One side of each part die cavity 1 all is connected to a horizontal running channel 4 through an ingate 3, and laterally running channel 4 middle parts also are provided with vacuum-pumping system through main running channel 5 connection sprue gates 6; Said vacuum-pumping system comprises that being arranged in each part die cavity bleeds 7 away from an end of ingate; In 7 one ends (through slag trap) of bleeding link to each other with part die cavity 1, the other end is connected to one and laterally bleeds 8, said 8 middle parts of laterally bleeding 9 are connected to a vacuum suction device 10 through main bleeding.Wherein, Also be provided with the impurity of bleeding in the said vacuum-pumping system and eliminate structure; The said impurity of bleeding is eliminated structure and is positioned at the direction of flow turning point of bleeding; Comprise the curved cavity 14 in the cross section to outer lug that is positioned on the inwall of bleeding, said cavity 14 over against fluid come to the position be provided with.Also be provided with the vacuum suction device buffer structure in the said vacuum-pumping system; Said vacuum suction device buffer structure is connected between vacuum suction device and main the bleeding; Comprise a first passage 11, a second channel 12 and a third channel 13; The middle part of said first passage 11 and vacuum suction device 10 inlet vertical connections; One end vertical connection of one end of said second channel 12 and first passage 11, an end of said third channel 13 and the other end vertical connection of second channel 12, the other end of said third channel 13 and main 9 vertical connections of bleeding.The said vacuum suction device 10 preferred vacuum valves that adopt during practical implementation.
In the above-mentioned automobile die casting parts cast channel system, be provided with vacuum-pumping system, like this; When cast, after drift arrives the casting of molten metal injection molten cup batch turning seal position, can start vacuum suction device work; Vacuum suction device extracts away the air in the part die cavity through vacuum-pumping system; Product is the space of few air in the space that forms so, and molten metal can not run into air drag when filling, and is convenient to molten metal and in part die cavity, fills moulding smoothly; The inner pore of product will reduce after the moulding, has greatly improved product quality.During practical implementation, said vacuum suction device belongs to ripe prior art, can directly adopt formation such as existing vacuum valve or vavuum pump.
Wherein, be provided with the impurity of bleeding and eliminate structure, like this; In vacuumizing the process of filling with molten metal; Coating in the mold cavity in some mold cavities that can't eliminate fully or aluminium bits will be washed into the circular arc place by air-flow and molten metal, with the cancellation from the fluid of bleeding of these impurity, avoid it directly to be washed into and cause vacuum valve blocked in the vacuum valve; Raising is protected effect to vacuum valve, ensures carrying out smoothly of producing.
Simultaneously; Also be provided with vacuum suction device buffer structure (being the utility model structure), like this, can avoid fluid high-speed directly to impact vacuum valve; Cause vacuum valve to be washed out; Impurity in bleeding simultaneously also can directly not enter into vacuum valve and result in blockage, and further improves vacuum valve protection effect, improves the stability of a system.
In sum, above-mentioned automobile die casting parts cast channel system is through the mode that vacuumizes; Created the space of a few air; Avoided air holes the product inside from root as far as possible, improved product quality, molten metal is filled resistance when also having reduced cast simultaneously; Possess the good characteristics of self stability of a system, ensured carrying out smoothly of producing.
