Description
Technical field
This utility model belongs to casting technology field, is specifically related to a kind of one case more than one piece casting mold of biplate brake disc.
Background technology
Brake disc i.e. brake disc, is with steel alloy manufacture and to be fixed on wheel, and with the automobile brake parts of vehicle wheel rotation, when touching on the brake in vehicle travel process, brake caliper is clamped brake disc and played the effect slowed down or stop.At present, the brake disc that all kinds of automobiles are widely used can be divided into drum-type and the big class of disc type two according to the difference rotating element.Difference between them is: the rotation element in drum brake dish friction pair is brake drum, with its face of cylinder as working surface, because its cost is relatively low, absolute brake power high, more it is used in the trailing wheel of pony car, needed on truck that brake force is big and bus, but its rate of wear is higher, it is not suitable for high-speed small-size vehicle；Rotation element in disc brake rotor friction pair is discoid brake disc, and with its end face as working surface, it has preferably reactive and stability, perfect heat-dissipating, simple structure, and maintenance, replacing simplicity, is widely used in high-speed small-size vehicle.
Biplate brake disc, as the one of disc brake rotor, circumferentially has many to lead to the air channel in the center of circle, and automobile realizes cross-ventilation by air channel in enforcement, thus reaches the purpose of heat radiation.Biplate brake disc dimension precision requirement is higher, and requirement for dynamic balance is high, and the hardness requirement of brake lining is strict, and conplane nonhomogeneous hardness is less than 10HB, is not allow for any casting flaw.
The traditional handicraft of casting biplate brake disc is to use clay-bonded sand moulding line at present, specification layout one type two pieces according to production line, three, a type or a type more pieces, precoated sand core or cold core core is generally used to do the loam core between two panels dish, external form is done with clay-bonded sand, this technique is high due to the relation production efficiency of production line, steady quality, but this technique there is also placer iron than high and that product yield is low problem.
Utility model content
The purpose of this utility model is to overcome disadvantages mentioned above present in prior art, it is provided that one can realize a type more than one piece, the biplate brake disc casting mold of stack casting, and this casting mold structure is the compactest, and placer iron ratio is little, and product yield is high, and steady quality and production cost are low.
To achieve these goals, the technical solution adopted in the utility model is as follows: one case more than one piece casting mold of biplate brake disc, including the bottom core being stacked from bottom to top and top core, middle core it is stacked with above the core of bottom, being stacked with combination core in the middle part of least one set above middle core, combination core in middle part therein is combined stacked by core in the middle part of core and first in the middle part of second from bottom to top；Often combine in the middle part of group and be each formed with biplate brake disc die cavity between core and between middle core and bottom core in the middle part of core and second in the middle part of the first of core；The center combining core and middle core in the middle part of top core, often group is the most longitudinally provided with the sprue being sequentially communicated, the center of bottom core be longitudinally provided with not through sprue base, each sprue is sequentially communicated up and down to sprue base.
In this utility model, further, all it is connected by ingate between each biplate brake disc die cavity and sprue.
In this utility model, it is preferred that the ingate between each biplate brake disc die cavity and sprue is three, and three ingate circumferences uniformly and are distributed between biplate brake disc die cavity and sprue to centroclinal.
In this utility model, further, top core is provided with multiple equally distributed steam vent, and steam vent connection is positioned at the biplate brake disc die cavity below the core of top.
In this utility model, further, the center above the core of top is provided with cup, and the junction of cup and top core is provided with drainage screen.
In this utility model, it is preferred that middle part combination core is five groups.
When applying casting mold of the present utility model casting biplate brake disc, being fixed in lock box by casting mold, the bottom core chassis supports of casting mold, top core covers with circular cast iron surface plate, by the regulation circular cast iron surface plate of bolt locking above lock box, to compress casting mold；Metal liquid enters sprue from cup, metal liquid is filled by the biplate brake disc die cavity being positioned at bottom, last layer biplate brake disc die cavity is refilled after this layer of biplate brake disc die cavity is full of, being full of each biplate brake disc die cavity of whole casting mold from bottom to top, the gas produced in casting cycle escapes from steam vent.
The beneficial effects of the utility model are: casting mold structure of the present utility model is the compactest, are not limited by the specification layout institute of conventional production lines, and casting mold of the present utility model can be by the quantity of actual demand stacked middle part combination core, it is achieved the casting purpose of a type more than one piece；When applying casting mold of the present utility model to cast, metal liquid while cooled and solidified, by each core heat-agglomerating from inside to outside of casting mold, makes each core in casting mold the most defeated and dispersed in casting mold, and the foundry goods being in red heat state leaks the most cruelly at air
, make biplate brake disc foundry goods accelerate rate of cooling, improve biplate brake disc cast(ing) surface hardness, while reducing placer iron ratio, reduce the workload of sand removal, improve the yield rate of biplate brake disc foundry goods, additionally, the old sand after defeated and dispersed is easily recycled；The gas produced in casting cycle escapes from the steam vent of top core, improves filling velocity, reduces biplate brake disc foundry goods and produces the tendency of pore, it is ensured that the stability of biplate brake disc casting quality, reduces production cost.
