Description
Technical field
The present invention relates to a kind of mould, produce sample when being used for aluminum alloy spectrum analysis.
Background technology
In aluminum alloy spectrum analysis, only gather several points of analyzing face of sample during analysis, so the mode of producing of sample is very crucial, is the principal element that influences the spectral analysis accuracy.
As depicted in figs. 1 and 2, be a kind of structural drawing of sample mold commonly used, form by a bed die seat 4 with by left die holder 1, right die holder 2 that bolt 3 is hinged on the bed die seat 4.A left side die holder 1, right die holder 2 are relative, and its profile is roughly bed die seat 4 half.Be that the center is formed with taper sprue gate 10b and is the circular die cavity 10a of bottom surface with bed die seat 4 upper surfaces with relative piece on left die holder 1 and right die holder 2, bed die seat and left and right sides die holder adopt mould steel H13 or QT60-2 material.On bed die seat 4, mould is installed, on left die holder 1 and right die holder 2, is separately installed with mould, so that control left and right die holder matched moulds casting sample and separate left and right sides die holder to take out sample from both sides 11,21 41.What this sample mold formed is the mushroom sample, and die cavity 10a and sprue gate 10b also can adopt other formation, samples such as cylindric to form, coniform, forked, U-shaped shape, round pie.
Present this mould is materialsed all and to be had in various degree defective, as radially segregation, vertically segregation, analysis face representative poor, data reappearance is poor, particularly there is macrosegregation, suppressed the expansion of spectral analysis to the heavy contend analysis field for the high-load element.Also exist sample to be unfavorable for deficiencies such as machining in addition.
The utility model content
At the component segregation deficiency that bring and that bring thus that the present sample that sample mold produced exists, the purpose of this utility model is sample mold is improved to improve the segregation problem of sample.
The utility model adopts following technical scheme: a kind of aluminum alloy spectrum analysis sample mold, comprise bed die seat and the left die holder that is hinged on the bed die seat, right die holder, at the piece with left die holder and the relative side of right die holder is that the position at center is formed with sprue gate and die cavity, it is characterized in that: the position of corresponding described die cavity is provided with the bed die mold insert on described bed die seat top, left mould mold insert and right mould mold insert are housed respectively around die cavity in described left die holder and right die holder, make that described die cavity is to constitute described bed die mold insert by the space that bed die mold insert and left mould mold insert and right mould mold insert are surrounded, left side mould mold insert and right mould mold insert adopt fusing point to be higher than the sample alloy and heat transfer system is higher than bed die seat and left die holder, the material of right die holder.
Described bed die mold insert, left mould mold insert and right mould mold insert all can adopt has the copper that higher heat transfer coefficient and fusing point are higher than aluminium, particularly favourable with red copper.
Utility model people is through studying discovery for a long period of time, cause the reason of sample composition segregation relevant with the cooldown rate of melt and sample, this aluminum alloy spectrum analysis sample mold of the present utility model, at the bed die seat, be provided with mold insert in left side die holder and the right die holder, mold insert adopts heat transfer coefficient to be higher than a bed die seat and a left side, the material of right die holder, simultaneously because the thickness that these mold inserts have also reduced the die holder with low heat transfer coefficient is installed, therefore casting back melt and sample rapid heat dissipation can be realized quenching, reduced composition radially, vertically segregation, and then improved sample analysis face representativeness, data reappearance.

Fig. 4 cuts open synoptic diagram for the side of sample mold shown in Figure 3.
Embodiment
Below in conjunction with accompanying drawing and a specific embodiment aluminum alloy spectrum analysis of the present invention is described further with sample mold, to help understanding content of the present invention.
As shown in Figure 3 and Figure 4, be a kind of synoptic diagram that is used to prepare the sample mold of round pie sample.Comprise by the bed die seat 4 of H13 or QT60-2 material with by bolt 3 being hinged on left die holder 1, right die holder 2 on the bed die seat 4, at the relative side position of left die holder 1 and right die holder 2, being that the center is formed with sprue gate 10b and die cavity 10a to the piece pieced together.The position of corresponding die cavity 1a studs with bed die mold insert 4a on bed die seat 4 tops, studs with left mould mold insert 1a and right mould mold insert 2a in left die holder 1 and right die holder 2 around die cavity respectively.Bed die mold insert 4a, left mould mold insert 1a and right mould mold insert 2a adopt fusing point to be higher than the red copper material that sample alloy and heat transfer system are higher than bed die seat and left die holder, right die holder, make that die cavity is to be made of the space that the bed die mold insert 4a of red copper and left mould mold insert 1a and right mould mold insert 2a are surrounded, the high heat transfer coefficient that utilizes red copper is to improve the rate of heat dispation of the aluminium alloy melt after casting, improve melt solidifying speed and sample cooling rate, reduce the composition segregation.Be provided with the mould handle on bed die seat and the left and right sides die holder.
Bed die mold insert 4a can be fixed on the bed die seat 4 by bolt 4b, and left mould mold insert 1a also is fixed on the left die holder 1 by two screw 1b, and right mould mold insert 2a is fixed on the right die holder 2 by two screw 2b.Certainly each mold insert is except that can adopting bolt or screw retention, and each mold insert can also adopt other fixed form.
Can be provided with the protruding 4a1 of arc surface in the corresponding die cavity 10a of bed die mold insert 4a center, its purpose one is to reduce the thermal capacity in sample centre, increases the Quench degree of whole sample; The 2nd, can form a recess in the sample center, in the time of can avoiding machining because of knife rest the higher or on the low side sample center injustice that causes, be convenient to the plane processing of the face of analyzing.
The sprue gate 10b of described left die holder and right die holder piece position is 35 ° to adopt angle α, and back cut diameter d is that the taper of 35mm is ideal.Angle and upper oral part are excessive, and the sprue gate big melt of capacity holds the heat energy that contains and is unfavorable for heat radiation, the too small melt cast that is unfavorable for of angle and osculum diameter more.
Die cavity 10a and 10b can be round pie, cylindric, coniform, forked, U-shaped shape, mushroom etc. according to the shape need of sample.In adopting present embodiment during mushroom, more advantageously die cavity 10a diameter is 58mm, highly adopt 5mm, with the diameter 63mm of original usefulness highly be the die cavity of 8mm, the area and the volume of sample cake part under the prerequisite of the analysis face of assurance, have been reduced, used melt amount is little during casting, so cooling velocity is faster, helps improving segregation phenomena.
Through overtesting, the sample that adopts this mould to produce, compare with the sample that original mould is made, the analysis face representativeness of materialsing, element homogeneity all have clear improvement, reappearance after processing repeatedly etc. all has raising largely, and analysis face is convenient to machining, makes photoelectric method analyze that each content range section precision of each element all can reach the GB requirement in the aluminium alloy, for the expansion of spectral analysis to the high-load field provides the sample assurance.
