Description
Technical field
The utility model relates to a kind of casting device, particularly relates to a kind of casting device of the production in enormous quantities brake disc of high-speed train disk body be applicable under large bag pouring condition, and brake disc disk body obtained thus.
Background technology
Brake disc disk body is the critical component of bullet train, plays an important role when train braking.Because its working environment is complicated severe, maintain and replace inconvenience.Require that brake disc product must have stable quality and longer service life.
Large quantity research shows, when material is certain, the main cause that casting brake disc disk body lost efficacy there is the casting flaws such as shrinkage cavity and porosity, sand hole, crackle in disk body.
The bullet train of more than 250km/h speed, the quality of brake disc disk body is had higher requirement, the tolerance of the casting flaws such as shrinkage cavity and porosity, sand hole, pore, cinder hole, crackle is reduced further, meanwhile, strict restriction has also been made to the content of the gas in material and field trash.This all requires to have corresponding rational running gate system and system of risers to ensure.
Because brake disc disk body single-piece quality is light, single-piece or small number foundry goods, when one case cast, take moulding place large; For meeting casting quality requirement, parcel must be adopted to pour into a mould; Again because brake disc disk body is high to material requirements, chemical Composition Control is strict, particularly requires strict to field trash and N, H, O gas content, must melting in refining furnace, can not carry out maybe will avoiding carrying out ladle-to-ladle operation of Denging.At present, market is large to the quantity required of this foundry goods, and within using 5T, parcel cast production efficiency is low, is difficult to meet market demands.Therefore, a kind of high efficiency producing process and production method that 5T and even more than 15T can be used to wrap greatly cast of exploitation is badly in need of.
Publication number is the overlapping pouring technology that the patent of invention of CN103317099A discloses a kind of brake disc, first makes bed die, main mould, cover mold, and the cast of disjunctor, water inlet and the feeding decorum are ganged up in design up and down; Then the metal frock such as base plate, cover volume, cover plate is made; Again model group is installed on core shooter, utilizes the air pressure of core shooter by the full model of sand pressure, by be heating and curing shaping after, take out pile up for subsequent use; Finally each part mentioned above is assembled, and lay casting compencation cup, wait to be cast.The casting technique efficiency of this patent of invention is high, but also can only prepare the brake disc being applicable to automobile that material is cast iron.
Summary of the invention
For solving problems of the prior art, the utility model provides a kind of casting device of brake disc disk body, it comprises running gate system and system of risers, described running gate system comprises cup, sprue, cross gate, ingate and rectification filter, described system of risers comprises rising head and subsidy, go here and there vertical with system of risers of described running gate system stacks, the rising head of the system of risers of lower one deck substitutes the running gate system of last layer, and described rising head center is placed in any position of foundry goods madial wall to foundry goods geometric center.It is the folded cast of multilayer string that this running gate system and system of risers achieve brake disc foundry goods.The mode adopting the end to return introducing molten metal is carried out string and is watered, and molten metal, by entering this stratotype chamber bottom lower one deck, enters last layer die cavity by the rising head of this layer after this stratotype chamber is full of.
