Abstract
A kind of turbine case precoated sand cast structure that the utility model is related to, it includes sprue cup（1）, riser（2）With casting body（4）, it is characterised in that the riser（2）Inside it is provided with filter（3）, the filter（3）It is vertically arranged in filter（3）Neck side.The utility model changes filter position when passing through technological design, so as to control linear velocity of molten iron when type is filled, reduces impact dynamics of the molten iron to filter, reduces the generation of Secondary Oxidizing Slag, improve the final finished rate of product.
Description
Technical field
It the utility model is related to a kind of turbine case precoated sand cast structure.
Background technology
General precoated sand Foundry Works, when designing precoated sand sand mold, for the raising of product yield, is typically chosen one
The mode that kind is directly poured, molten iron are poured into a mould directly above riser, this riser functions simultaneously as the role of cast gate and riser.Therefore, filter
The general design of placement of piece position, which is typically chosen, to be placed on inside sprue cup.But asked in process of production there are following
Topic：
1st, the direct impact filtration piece of molten iron, causes filter to crush；
2nd, the direct impact filtration piece of molten iron, then under placement in height, into riser neck, molten iron turbulent flow is serious, and casting easily goes out
Existing Secondary Oxidizing Slag；
When the 3rd, pouring into a mould, filter easily floats, and does not have pushing off the slag effect.
The content of the invention
A kind of the purpose of this utility model is to overcome above-mentioned deficiency, there is provided turbine case precoated sand cast structure.
What the purpose of this utility model was realized in：
A kind of turbine case precoated sand cast structure, it includes sprue cup, riser and casting body, it is characterised in that described to emit
Filter is provided with mouthful, the filter is vertically arranged in the neck side of filter.
As a preferred embodiment, the filter is 5mm apart from the lateral separation of the neck of riser.
As a preferred embodiment, the height that the neck of riser is higher by the top of the filter is 10mm-20mm.
Compared with prior art, the beneficial effects of the utility model are：
The utility model have changed the design of filter position, and traditional position is lies in a horizontal plane in sprue cup, riser
Surface.Now it is changed to place between riser and casting pouring boss, i.e., riser neck position is placed.It is to prevent filter shadow at the same time
Ring the feeding of casting, the shape of riser also respective change.Filter position is changed when passing through technological design, so as to control molten iron to exist
Linear velocity when type is filled, reduces impact dynamics of the molten iron to filter, reduces the generation of Secondary Oxidizing Slag, improve product
Final finished rate.
Brief description of the drawings
Fig. 1 is the top view of the utility model.
Fig. 2 is the A-A sectional views of Fig. 1.
Wherein：
Sprue cup 1, riser 2, filter 3, casting body 4.
Embodiment
Referring to Fig. 1-Fig. 2, a kind of turbine case precoated sand cast structure that the utility model is related to, it includes sprue cup 1, emits
Mouthfuls 2 and casting body 4, filter 3 is provided with the riser 2, and the filter 3 is vertically arranged the neck one in filter 3
Side, the lateral separation of neck of the filter 3 apart from riser 2 is 5mm, and the top of the filter 3 is higher by the neck of riser 2
Height be 10mm-20mm.
Operation principle：
During cast, the direct repercussion riser base bottom of molten iron, after reducing potential energy impact, linear velocity reduces, and molten iron is emitting
Oral pit bottom is circled round, and then enters back into filter.Filter recurrence reduces the effect of linear velocity to a part, and molten iron flows into casting
When will become gentle, stablize fill type, no splashing, no turbulent flow, effectively reduces oxidizing slag.
