Technical field
The utility model relates to the casting core assembling technology, particularly relates to a kind of air-flow or atomized water spray device of controlling the core assembly casting cooling speed.
Background technology
Multiple-core casting technique has the advantages such as casting dimension is accurate, surface quality good, system sand is convenient to recycle, and is widely used.But to be the foundry goods cooling velocity slow and be not easy control for the shortcoming that multiple-core casting is compared with permanent mold casting or tide mould sand, is difficult to realize consecutive solidification or Welding by local rapid cooling, is difficult to guarantee the inherent compactness of local thick and large casting.In the situation about having, even the chill of usage comparison trouble can not arrive desirable result.High, complex-shaped and foundry goods local thermal center has certain limitation to this shortcoming so that multiple-core casting technique is to quality requirement, such as the aluminium alloy cylinder cylinder head casting of automobile industry.
Multiple-core casting all adopts the nature cooling means to realize molten metal solidifying in sand mold at present, but because the sand mold poor thermal conductivity, accumulation of heat is little and self run into molten metal also generates heat, so that the foundry goods cooling velocity is slow, and be not easy to control, be difficult to realize consecutive solidification or Welding by local rapid cooling, be difficult to guarantee the inherent compactness of local thick and large casting, in the situation about having, even the chill of usage comparison trouble can not arrive desirable result.
Summary of the invention
The purpose of this utility model provides a kind of air-flow or atomized water spray device of controlling the core assembly casting cooling speed.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of air-flow or atomized water spray device of controlling the core assembly casting cooling speed, it comprises framework, air-flow or water fog generator and injection apparatus, described air-flow or water fog generator are connected with described injection apparatus, and described injection apparatus can spray the sand mold that is placed in the described framework.
Preferably, described injection apparatus includes several shower nozzles, and described shower nozzle can be aimed at the sand mold that is placed in the described framework and spray.
Preferably, described air-flow or water fog generator and injection apparatus are provided with many groups, organize more described air-flow or water fog generator and injection apparatus be arranged on described framework around or the bottom.
Preferably, be provided with in the described framework for the fixing hold assembly of sand mold.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
The utility model utilizes external physical cooling way-air-flow or atomized water spray, and device is controlled the cooling velocity of multiple-core casting diverse location, realize fast cooling and local fast cooling, guarantee the inherent quality of foundry goods, so that multiple-core casting technique can be used for be produced the foundry goods of high, the complex-shaped and local thermal center of quality requirement in enormous quantities, such as the aluminium alloy cylinder cylinder cap of automobile industry etc.
