Description
Technical field
The utility model relates to Casting Technology field, specifically a kind of contoured foam running gate system model.
Background technology
At present, when the impeller casting of production cast steel, that former casting technique adopts is middle pouring-in (as figure mono-), namely impeller impression top is provided with top rising head, impeller casting sealed bottom ring portion position 5 be thick large thermal center, by top rising head 6 again feeding less than, use chill not reach ideal effect again, cause between impeller cover and blade 4, shrinkage porosite appears in the sealing ring position 5 of impeller bottom; There is cold shut in blade 4, the defects such as fire of choking.
Summary of the invention
The purpose of this utility model solves above-mentioned the deficiencies in the prior art, provide a kind of rational in infrastructure, improve castability, prevent shrinkage porosite, the contoured foam running gate system model of cold shut, the casting flaws such as fire of choking.
The utility model solves the technical scheme that its technical problem adopts:
A kind of contoured foam running gate system model, comprise impeller impression, described impeller impression top is provided with top rising head, it is characterized in that being provided with running gate system model bottom described impeller impression, it comprises sprue mould, ingate mould and cast gate snap, described ingate mould is backed to center gradually to the other end by sprue contact jaw and forms taper type, described sprue mould becomes cylindrical, being beneficial to feeding top riser cannot the thermal center of feeding, described cast gate snap becomes hemispherical, be beneficial to the feeding efficiency improving rising head, the big opening end upper end of described ingate mould is connected with sprue mould end opening, big opening end lower end is connected with cast gate snap, the osculum end of described ingate mould is connected with side bottom impeller impression, be beneficial to adopt the sizing of applicable cast steel solidify principle to riser feeding in pump vane casting less than, the heat energy-saving position that chill cannot reach ideal effect has carried out effective feeding.
The utility model owing to adopting said structure, have rational in infrastructure, improve the advantage such as castability.
accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is the structural representation of the utility model embodiment.
Reference numeral: sprue mould 1, ingate mould 2, cast gate snap 3, blade 4, sealing ring position 5, top rising head 6.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in drawings, a kind of contoured foam running gate system model, comprise impeller impression, described impeller impression top is provided with top rising head 6, it is characterized in that being provided with running gate system model bottom described impeller impression, it comprises sprue mould 1, ingate mould 2 and cast gate snap 3, described ingate mould 2 is backed to center gradually to the other end by sprue contact jaw and forms taper type, described sprue mould 1 one-tenth is cylindrical, being beneficial to feeding top riser cannot the thermal center of feeding, described cast gate snap 3 one-tenth hemisphericals, be beneficial to the feeding efficiency improving rising head, the big opening end upper end of described ingate mould 2 is connected with sprue mould 1 end opening, big opening end lower end is connected with cast gate snap 3, the osculum end of described ingate mould 2 is connected with side bottom impeller impression, be beneficial to adopt the sizing of applicable cast steel solidify principle to riser feeding in pump vane casting less than, the heat energy-saving position that chill cannot reach ideal effect has carried out effective feeding.
The utility model is when casting the impeller of cast steel, according to the coagulating property of cast steel, the cast of directional solidification mode is carried out to top rising head and running gate system model simultaneously, utilize the utility model, after resin sand sclerosis, foam is taken out from molding sand, and by the cavity paint of formation of foam, form a blind riser, thus feeding can be carried out to the bottom thermal center of impeller, the bottom thermal center of impeller casting is avoided to produce the casting flaw such as shrinkage porosite, blade 4 cold shut because molten steel feeding is not enough, as shown in Figure 2.
The utility model owing to adopting said structure, have rational in infrastructure, improve the advantage such as castability.
