Description
Technical field
The utility model relates to spectral detection mould technical field, specifically a kind of sampling mould for molten iron spectral analysis.
Background technology
In foundry industry, the chemical composition constituent content of liquid metal on product structure and properties impact very large, the constituent content adopting spectral instrument analytical sampling sample to detect stove inner metal liquid in prior art more.And the Stability and veracity of chemical composition is not only relevant with spectrometric instrument, the mould also used in manufacturing process with sample is closely related.
When doing spectral detection to cast iron sampling, air chill must be carried out, otherwise testing result is by inaccurate.Therefore be exactly meet the air chill of sample after sampling to the requirement of sampling mould.
The sampling mould adopted in prior art is made up of with the die body at cylindric sprue gate and one flat plate shape base plate a middle part mostly, and its material is iron and steel.The shortcoming of this sampling mould is mainly: 1. due to materials that what need is only less cylinder schistose texture below sprue gate and cast passage, and the architectural feature at cylindric sprue gate determines above the mould that obtains and has most of column structure, this not only wastes material, is also unfavorable for follow-up cutting.2. tabular base plate does not have clip to die body and fixation, and when pouring into a mould, the turgor pressure existed during mobility and cooling due to liquid metal, easily causes the air chill of sample uneven, the first-class defect of density unevenness.3., because the heat conductivility of iron and steel is not fine, therefore materialsed air chill degree is bad, and sample defect is more, affects monitoring result.
Utility model content
The utility model will solve: spectral analysis sampling mould structure of the prior art built on the sand, cooling is steady, and sample grinds inconvenience and the technical matters such as waste of material is larger.
The utility model is for solving the problems of the technologies described above, the technical scheme adopted is: a kind of sampling mould for molten iron spectral analysis, comprise die body and pad the base plate be located at below die body, the upper surface of described base plate offers the groove for accommodating die body, and the inwall of this groove is the inclined-plane with certain slope, the bottom excircle of described die body is provided with the slope angle matched with this inclined-plane, described die body is made up of the left die body be symmetrical set and right die body, the top of the one side that left die body and right die body connect all offers a breach, two breach form a horn-like sprue gate for pouring molten iron together, the below at this sprue gate is connected with a cylindric ingate be butted into by the strip groove on left die body and right die body, the below of ingate is provided with a spectrum test block mould be butted into by the cavity on left die body and right die body, described horn-like sprue gate, ingate and spectrum test block mould be one continuously, and symmetrical cavity-like structure.
The gradient on described inclined-plane is 0.5-1.5.
The material of described die body is steel, and the material of base plate is red copper.
The beneficial effects of the utility model:
1, a kind of sampling mould structure for molten iron spectral analysis of the present utility model simple, design ingenious, by arranging horn-like sprue gate on symmetrically arranged left and right die body, not only stock utilization is high to adopt the perpendicular laminar sample prepared by mode watered, and the greatly less follow-up workload treatment step such as grinding, meanwhile, horn-like sprue gate facilitates the operability of cast.
2, a kind of sampling mould for molten iron spectral analysis of the present utility model, base plate upper outer circumference has the setting of the pickup groove of certain slope, enhance the steadiness of structure, when efficiently solving cast, due to the mobility of liquid metal and the turgor pressure of existence when cooling, make sample Forming Quality poor, easily there is positioning phenomenon in chill, meanwhile, easily cause the air chill of sample uneven, the first-class defect of density unevenness.
3, a kind of sampling mould for molten iron spectral analysis of the present utility model, the selection of material is specifically selected die body material be steel, base plate material is red copper, the good thermal conductivity of red copper can ensure that materialsed live part air chill has good degree, improves the accuracy that material spectrum is analyzed.

Graphical indicia: 1, die body, 101, left die body, 102, right die body, 2, base plate, 3, sprue gate, 4, spectrum test block mould, 5, inclined-plane.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described:
A kind of sampling mould for molten iron spectral analysis, comprise die body 1 and pad the base plate 2 be located at below die body 1, the material of described die body 1 is steel, the material of base plate 2 is red copper, the upper surface of described base plate 2 offers the groove for accommodating die body 1, and the inwall of this groove is the inclined-plane 5 with certain slope, the gradient on this inclined-plane 5 is 0.5-1.5, and the bottom excircle of described die body 1 is provided with the slope angle matched with this inclined-plane 5, described die body 1 is made up of the left die body 101 be symmetrical set and right die body 102, the top of the one side that left die body 101 and right die body 102 connect all offers a breach, two breach form a horn-like sprue gate 3 for pouring molten iron together, the below at this sprue gate 3 is connected with a cylindric ingate be butted into by the strip groove on left die body 101 and right die body 102, the below of ingate is provided with a spectrum test block mould 4 be butted into by the cavity on left die body 101 and right die body 102, described horn-like sprue gate 3, ingate and spectrum test block mould 4 be one continuously, and symmetrical cavity-like structure.
A kind of sampling mould for molten iron spectral analysis of the present utility model is when use procedure, first by left die body and the inner wiped clean of right die body, symmetrical spelled after by left die body with right die body is supporting is fastened in groove that plate upper surface offers, now, slope angle on die body coordinates completely with the inclined-plane of groove excircle, ensure that the stationarity of metal cooling procedure.During cast, the horn-like sprue gate cast molten steel formed from left die body and right die body top, the larger aperture area in horn-like sprue gate greatly reduces the operation easier of cast process.Ingate less below sprue gate and laminar spectrum test block mould not only avoid the waste of material, also because less volume shortens the diffusion time of molten steel, reduce the solidifying segregation of molten steel, make sample crystal grain even.Perpendicular mode of watering also makes laminar spectrum test block mould not easily produce slag inclusion, and air chill is complete.
After sample cools completely, pull down left die body and right die body, take off sample, deliver to related equipment and polish, afterwards, can spectrum test use be carried out.It is accurate that spectrum samples prepared by this mould analyzes data, good stability, and speed is fast.
