Description
Technical field
This utility model relates to valve body moulding technical field, is specially a kind of high pressure valve body moulding.
Background technology
Though China is construction machinery production big country at present, but industry is strong greatly and not, low-and-medium-grade products production capacity surplus, high-grade liquid
Pressure element almost all dependence on import, the development of Hydraulic Industry seriously lags behind the development of main frame industry, becomes restriction for equipment
The Main Bottleneck of development of manufacturing.At present, China's hydraulic part industry integral fabrication technique level compared with international advanced country still
There is bigger gap.Project Product, as construction machinery hydraulic system key components and parts, has that integrated level is high, highly reliable, the life-span
The advantages such as length, Project Product is high in technological content, alternative import, simultaneously can also for export, and product embodies higher casting
Technical merit, maintains the leading position at home.Project Product purposes is extremely wide, and market demand is relatively big, promise well.But
The less stable in the loam core of current valve inner, flexible.
Utility model content
The purpose of this utility model is to provide a kind of high pressure valve body moulding, with asking of solving to propose in above-mentioned background technology
Topic, is had the beneficial effect that by using special E font stud to fix the loam core of suspension, is enhanced the bending resistance in loam core
Performance, by using the special chill of self-control to combine the techniques such as high exothermic riser, reaches rapid condensation feeding effect, optimizes foundry goods material
Matter tissue, solves foundry goods shrinkage cavity shrinkage porosity problem.
For achieving the above object, this utility model following technical scheme of offer: a kind of high pressure valve body moulding, cast including valve body
Part body, main casting gate, vertical run and stud, the upper surface of described valve body moulding body is provided with main casting gate and auxiliary is watered
Geat, and main casting gate with auxiliary sprue gate outside be all provided with chill height exothermic riser, described main casting gate and valve body moulding
The vertical run connection of body interior, the side of vertical run is provided with sand-spraying hole, and described vertical run passes through the second horizontal run
Connecting with the first horizontal run, the first horizontal run is provided with reinforcement, and reinforcement is provided with stud.
Preferably, the upper surface of described valve body moulding body is provided with four main casting gates and four auxiliary sprue gates, and main
The diameter of casting gate is more than the diameter at auxiliary sprue gate.
Preferably, described second horizontal run is positioned at the top of the first horizontal run.
Preferably, described stud is positioned at the lower section of the first horizontal run, and stud is E font.
Compared with prior art, the beneficial effects of the utility model are: this equipment is by using special E font stud solid
The fixed loam core suspended, enhances the anti-bending strength in loam core, by using the special chill of self-control to combine the techniques such as high exothermic riser, reaches
To rapid condensation feeding effect, optimize castings material tissue, solve foundry goods shrinkage cavity shrinkage porosity problem.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-3, a kind of embodiment that this utility model provides: a kind of high pressure valve body moulding, including valve body moulding
Body 1, main casting gate 2, vertical run 6 and stud 10, the upper surface of valve body moulding body 1 is provided with main casting gate 2 and auxiliary
Sprue gate 4, the upper surface of valve body moulding body 1 is provided with four main casting gates 2 and four auxiliary sprue gates 4, and main casting gate 2
Diameter is more than the diameter at auxiliary sprue gate 4, and main casting gate 2 is all provided with chill height exothermic riser with the outside assisting sprue gate 4
3, main casting gate 2 connects with the vertical run 6 within valve body moulding body 1, and the side of vertical run 6 is provided with sand-spraying hole 5, vertically
Runner 6 is connected with the first horizontal run 7 by the second horizontal run 9, and the second horizontal run 9 is positioned at the upper of the first horizontal run 7
Side, the first horizontal run 7 is provided with reinforcement 8, and reinforcement 8 is provided with stud 10, and stud 10 is positioned at the first horizontal run 7
Lower section, and stud 10 is in E font.
Operation principle: in production process, uses method for rapid cooling, i.e. by by the fast quickly cooling of big chill before core deforms
But the method forming E font stud 10 makes the molten iron of periphery quickly cool down no longer to deform, take phenolic sand molding technique, logical
In overtesting preparation molding sand, resin improves die cavity intensity with the ratio of solidification.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
