Abstract
The invention discloses a kind of cooling grate plate of heavy truck traction seat micropore and its EPC ceramics sand core method production methods, including main body, main body to be equipped with air hole, air hole is distributed in main body in array, air hole is obliquely installed, and distance is 15mm between adjacent institute's air hole, and the width of air hole is 2mm.The length of main body is 500mm, width 400mm.The EPC ceramics sand core method production method of the cooling grate plate of heavy truck traction seat micropore, specific steps are as follows:, the model of casting is made with foam first；, on bubbles model fixed ceramics sand core；, binder is brushed on bubbles model；, bubbles model is put into evaporative pattern sandbox, air forming is taken out using negative pressure；, molten steel is poured by riser after, foam combustion removal.The present invention is produced using EPC ceramics sand core method, and it is very clear to cast out structure outline, the cooling grate plate of minimum-value aperture 2mm cement kiln, and can cast the middle-size and small-size structural member of other structures complexity, especially suitable for heavy truck traction seat.
Description
Technical field
The present invention relates to a kind of cooling grate plate of heavy truck traction seat micropore and its EPC ceramics sand core method production methods.
Background technique
Grate plate plays the role of support, but the aperture in grate plate is excessive, and air-flow can be excessive, will lead to the supporter in grate plate
Uneven heating, once uneven heating, will lead to casting overall performance and does not reach requirement, and the performance to entirety of heavy truck traction seat
It is required that high.Cement kiln is simple with the cooling grate plate structure of heat resisting steel, has air hole intensive above, aperture is excessively small, due to hole
It is more and aperture is small.Ordinary sand casting technique, minimum cast out hole and are greater than 5mm, it is difficult to ensure that 100% profile in modeling process
Clearly open-work, so casting yield is very low in process of production, economic benefit is poor, and in actual use, wind pressure
Lose larger, waste of energy.Traditional EPC technique, dry sand are difficult to fill consolidation small-bore 2mm inner hole, cause penetration, it more difficult to
To remove.It follows that cement kiln is smaller with heat resisting steel grate plate overall dimensions, belong to small-sized casting, but due to grate plate above
Aperture it is small and more, the fuse that is formed when with ordinary sand casting it is difficult to ensure that aperture profile and size, and aperture
Fuse production trouble, casts out hole if do not done, and extremely difficult using machining drilling on heat-resisting steel casting, process costs are high, nothing
Method is used for production.Lost foam casting (Expendable casting proces abbreviation EPC) is that foam mould uses
Bindless dry sand combines, the cavityless casting of vacuum pumping technology.The cooling grate plate technical requirements aperture of heat resisting steel is directly cast in 2mm
Clear-cut open-work out, to guarantee to establish cooling wind pressure.
Summary of the invention
Goal of the invention: the purpose of the present invention is to solve deficiency in the prior art, provide it is a kind of have cast out profile
The clearly grate plate of open-work, to guarantee the cooling grate plate of the heavy truck traction seat micropore for establishing cooling wind pressure and its EPC ceramics sand core method
Production method.
Technical solution: a kind of cooling grate plate of heavy truck traction seat micropore of the present invention, including main body, main body are equipped with air hole,
Air hole is distributed in main body in array, and air hole is obliquely installed, and distance is 15mm, air hole between adjacent institute's air hole
Width be 2mm.
A further improvement of the present invention is that the length of main body is 500mm, width 400mm.
A further improvement of the present invention is that a kind of EPC ceramics sand core method production of the cooling grate plate of heavy truck traction seat micropore
Method, specific steps are as follows:
, the model of casting is made with foam first；
, on bubbles model fixed ceramics sand core；
, binder is brushed on bubbles model；
, bubbles model is put into evaporative pattern sandbox, air forming is taken out using negative pressure；
, molten steel is poured by riser after, foam combustion removal.
The utility model has the advantages that
Compared with vertical air hole, wind-force is weakened the air hole being obliquely installed of the invention, reduces showing for uneven heating
As.It is very clear that the present invention can cast out structure outline, the cooling grate plate of minimum-value aperture 2mm cement kiln, and can cast it
His complicated middle-size and small-size structural member.
Detailed description of the invention
Fig. 1 is top view of the invention；
Fig. 2 is the left view invented；
Wherein, 1- main body；2- air hole.
Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book is understood other advantages and efficacy of the present invention easily.
Such as Fig. 1,2, a kind of cooling grate plate of heavy truck traction seat micropore, including main body 1, main body 1 are equipped with air hole 2, breathe freely
Hole 2 is distributed on the body 1 in array, and air hole 2 is obliquely installed, and distance is 15mm, air hole between adjacent institute's air hole 2
2 width is 2mm.
A further improvement of the present invention is that the length of main body 1 is 500mm, width 400mm.
A further improvement of the present invention is that a kind of EPC ceramics sand core method production of the cooling grate plate of heavy truck traction seat micropore
Method, specific steps are as follows:
, the model of casting is made with foam first；
, on bubbles model fixed ceramics sand core；
, binder is brushed on bubbles model；
, bubbles model is put into evaporative pattern sandbox, air forming is taken out using negative pressure；
, molten steel is poured by riser after, foam combustion removal.
The present invention is suitable for middle light casting, especially suitable for the heavy truck traction seat heat resisting steel grate plate being mentioned herein.First
The profile of casting and the accurate dimension at each position, assembling ceramic sand core are carried out with foam, baking and curing of coating is then placed in and disappears
Sand case is lost, back-up sand after good position is arranged, vacuumizes, moulding by casting, after being cooled to certain temperature, opens valve inflation, the grains of sand
It can voluntarily fall under gravity, mechanical means clears up sand core aperture.
Above-mentioned specific embodiment, only technical concept and structure feature to illustrate the invention, it is therefore intended that allow and be familiar with this
The stakeholder of item technology can implement accordingly, but the above content is not intended to limit protection scope of the present invention, all according to this hair
Any equivalent change or modification made by bright Spirit Essence, should all fall under the scope of the present invention.
