Abstract
The invention discloses a pouring technology of an aluminum inlet manifold, which is carried out by means of low pressure pouring. The pouring technology comprises the following technical measures of: (1) setting a pouring position of a casting, (2) setting a pouring system, and (3) carrying out a pouring operation. Compared with the prior art, the pouring technology has the advantages that as a sprue is directly communicated with pressurizer tanks, one sprue can be communicated with two pressurizer tanks for the adoption of the low pressure pouring mode, two aluminum inlet manifolds can be poured simultaneously, namely, two pieces can be obtained by once pouring, and production efficiency is extremely high; simultaneously, a specially shaped pouring gate does not needed to be arranged and preparation is very convenient so that a preparation period is very short and preparation cost is pretty low, and the pouring gate is very short so that mold-filling capacity is pretty good, pouring deficiency is not easy to happen, and rate of finished products is very high; and an original flash groove is canceled and the pouring gate is pretty short so that process yield is further improved.
Description
Technical field
The present invention relates to a kind of pouring technology of aluminum alloy air inlet manifold.
Background technology
At present, the pouring technology of the aluminum alloy air inlet manifold of prior art is all that what to adopt is gravity-assist pouring, is not the horizontal gravity cast, is exactly the structure that tilting type gravity-assist pouring or tilting type gravity-assist pouring and ladder are poured into a mould; But the former pouring gate structure is more complicated, and sprue and rising head all are arranged on the position of aluminum alloy air inlet manifold away from pressurizer tank, be that dead head all is arranged on the flange face of aluminum alloy air inlet manifold, mold-filling capacity is relatively poor, is prone to the defectives such as cold shut and underpriming; Although and the latter can solve the problems such as the poor and cold shut of mold-filling capacity to a certain extent, also need to arrange snakelike main running channel and teeming road, the mould preparation bothers, and manufacturing cycle is longer, and cost is also higher; And said method can only be all one, a type, and namely a secondary mould can only be poured into a mould a product, and production efficiency is lower, and dead head is relatively large, cause product yield (casting technique yield rate=foundry goods is heavy/the heavy * 100% of mould.Mould is heavy, is exactly the gross mass of running gate system+foundry goods, also just waters a required weight of molten iron of mould.) lower.
Summary of the invention
The present invention is directed to the pouring technology that above problem provides a kind of mold-filling capacity not to be prone to better, that pouring defect, production efficiency are higher, the mould preparation is simple, manufacturing cycle is shorter, cost is lower and can improve the aluminum alloy air inlet manifold of product yield.
The present invention overcomes the above problems technical scheme used: a kind of pouring technology with aluminium aluminum alloy air inlet manifold of following steps is provided, adopts the low-pressure casting mode to carry out, comprise following technical measures:
1), the casting pouring position is set: the aluminum alloy air inlet manifold chamber is adopted from using horizontally set, and two aluminum alloy air inlet manifold chambeies are set, make the pressurizer tank in two aluminum alloy air inlet manifold chambeies all be positioned at the position of nearly cast gate, flange face position, aluminum alloy air inlet manifold chamber (1) all is positioned on position away from cast gate;
2), running gate system is set: described running gate system comprises cast gate and ingate, and its technical characterictic is: cast gate is positioned at the bottom of whole running gate system, and cast gate is communicated with two pressurizer tanks respectively by ingate;
3), pouring operation: directly be placed on low-pressure casting machine upper and get final product.
After adopting above technique, compared with prior art, the present invention is because cast gate directly is communicated with pressurizer tank, and by the mode of low-pressure casting, make a cast gate to be communicated with two pressurizer tanks, can be simultaneously two aluminum alloy air inlet manifold chambeies be poured into a mould, namely realize two, a type, production efficiency is higher; Do not need simultaneously to arrange the running channel of abnormity, prepare more conveniently, make manufacturing cycle shorter, preparation cost is lower, and the shorter mold-filling capacity of running channel is better, also is not prone to pouring defect, and yield rate is higher; Moreover cancelled original rising head, and running channel is also shorter, and then improved product yield.Therefore the present invention has the advantages that mold-filling capacity better, is not prone to pouring defect, production efficiency is higher, the mould preparation is simple, manufacturing cycle is shorter, cost is lower and can improve product yield.
as improvement, be provided with cross gate between described cast gate and ingate, described cross gate one end is communicated with cast gate, the cross gate other end is communicated with ingate, for the relatively complicated aluminum alloy air inlet manifold chamber of some structures, after cross gate is set, between cross gate and pressurizer tank, the quantity of ingate can be set according to the aluminum alloy air inlet manifold chamber of differing complexity, and then the speed of increase cast, prevent when structure relatively complicated aluminum alloy air inlet manifold chamber is poured into a mould, poring rate causes slowly because of the cooling too fast pouring defect that causes in part position, ingate also has the effect of feeding simultaneously, further improve the yield rate of cast.
