Abstract
The utility model relates to a die for sampling an aluminum alloy dregginess sample. The die comprises an upper die and a lower die which are aligned and fixed, wherein a dreg-contained aluminum alloy casting space is formed between the upper die and the lower die, a plurality of raised openings are distributed on the inner surface of the upper die, and a die cavity inlet of the upper die adopts a 45-degree inclined angle. A handle (5) is arranged at the top of the upper die. By adopting the die for sampling an aluminum alloy dregginess sample provided by the utility model, the sampling and the analyzing efficiencies can be improved, errors generated during sampling can be reduced to the utmost extent, and the testing results of sample pieces conform to the material objects (products).
Description
Technical field
The utility model relates to aluminium alloy Sampling techniques field, specifically is a kind of quick, succinct aluminium alloy dregginess sample collecting mould.
Background technology
Aluminium alloy mainly belongs to the bulk material of automobile industry, and along with automobile industry constantly develops, more and more stricter to the internal soundness requirement of aluminium alloy, must not there be serious shrinkage cavity customer requirement aluminium alloy inside, be mingled with.The analytical approach of the snotter in the aluminium alloy there are three kinds of qualitative analysis and semi-quantitative analysis, quantitative test.Wherein semi-quantitative analysis method adopts the K modulus method usually, and the advantage of this method is simple to operate, can judge the dregginess in the aluminium alloy comparatively intuitively.But adopt the dregginess in the K modulus method detection aluminium alloy, analyze mould and often have the following disadvantages:
1. the die cavity thickness of mould is too small, is unfavorable for that aluminium liquid flows, and easily causes original mold to fill the not enough and sampling failure of type.
2. mold wall thickness is oversize, and specific heat capacity is big, and heat absorption speed is fast, and aluminium liquid does not just solidify during complete filling, and filling effect is poor.
3. the mould design is unreasonable, is not easy to K mould section sampling and analysing.
Summary of the invention
The purpose of this utility model provides a kind of aluminium alloy dregginess sample collecting mould, can detect the inclusion content in the aluminium alloy, to the sampling of the aluminium liquid under the high temperature, realizes being mingled with half quantitative analysis of content by this mould.
The technical solution of the utility model is: aluminium alloy dregginess sample collecting mould is made up of upper die and lower die, and upper and lower mould alignment is fixing, forms slag inclusion aluminium alloy pouring space between upper die and lower die, and at the inner face of patrix a plurality of tangs that distribute
At the patrix top handle is arranged, just can not remove patrix easily when being convenient to the demoulding, take out sample by other instruments.The patrix mold cavity inlet is 45 ° pitch angle.
Aluminium alloy dregginess sample collecting mould of the present utility model has following characteristics:
1, detect requirement according to the K modulus method, the fracture that rationally distributes is convenient to the quantitative test with this mould institute sample thief, and realizes that primary sample can obtain a plurality of (5/time) end face as analytic sample, improves sampling, analysis efficiency.
2, take into full account the convenience of operator's sampling and accurate, the reliability of sample, reduce the error that sample collecting brings to greatest extent.(size of die cavity is strengthened by the appropriate design casting space, and the thickness by test and Selection and definite original mold) and original mold structure (the patrix mold cavity inlet is 45 ° pitch angle), when satisfying aluminium liquid and evenly flowing, obtain the cooling velocity identical with actual production.Promptly from the specific heat capacity angle, make the intensity of cooling of this original mold consistent with intensity of cooling in the process of producing product, the testing result of print conforms to (product) in kind.
3. the sample of getting by this mould can be realized the sample alternative sample in kind (product) of sampling fast, is convenient to the detection of aluminium alloy inclusion content, raises the efficiency.
Description of drawings
Fig. 1 is an aluminium alloy dregginess sampling mold structural drawing of the present utility model.
Fig. 2 is an aluminium alloy dregginess sample synoptic diagram.
Among the figure, 1-patrix, 2-counterdie, 3-tang, 4-angle, 5-handle.
Embodiment
Aluminium alloy dregginess sample collecting mould structure of the present utility model is made up of patrix 1 and counterdie 2 as shown in Figure 1, and upper and lower mould alignment is fixing, forms slag inclusion aluminium alloy pouring space between upper die and lower die, and at the inner face of patrix a plurality of tangs 3 that distribute.At the patrix top handle 5 is arranged, patrix mold cavity inlet 4 is 45 ° pitch angle.
Be held on the counterdie after in use patrix being alignd by pin, mould is inclined upwardly 30 ° then, be convenient to aluminium liquid toward current downflow, again aluminium liquid is poured into from the opening part of mould, after treating aluminium liquid cooling but, open patrix, tumble, can obtain aluminium alloy dregginess sample, as shown in Figure 2 with fracture.The sample of getting is prolonged fracture strike disconnectedly, obtain the section that dregginess detects, judge according to the quantity that is mingled with of section at last.
