Embodiment
Below through specific embodiment and combine accompanying drawing that the present invention is done further explain.Following examples are only further explained the present invention, should not be construed as limitation of the present invention.
The device of the casting metallographic observation sample in the present embodiment; Shown in Fig. 1-4, comprise patrix 1 and counterdie 2, patrix has first die cavity 11; First die cavity 11 is a both ends open square cone cavity; Lower end (big end) is communicated with second die cavity 21 when being used to fasten, the casting gate that upper end (small end) is used to cast, and the outer wall of first die cavity 11 is square column type; It is rounding taper type or cylindrical cavity that counterdie has second die cavity, 21, the second die cavities 21, and its open upper end only, is communicated with first die cavity 11 when being used to fasten, and the outer wall of second die cavity 21 also is square column type; The outside horizontal-extending of the chamber wall of second die cavity, 21 opening parts forms platform 22, and the outward flange of platform upwards vertically extends to form annular lip 23; The inwall of annular lip 23 is provided with internal thread 24; The chamber wall horizontal-extending at first die cavity, 11 lower ending opening places forms and cooperates with platform 22, and with the identical columniform patrix base 12 of annular lip 23 inwalls, base 12 outer walls are provided with the external thread 13 identical with internal thread 24; The groove 25 that has the opening that is set around counterdie 2 on the platform 22 is provided with groove 14 at patrix 1 corresponding to the place of groove 25, is plugged with O-ring seal 26 in the groove; When patrix 1 fastens with counterdie 2; First die cavity 11 and second die cavity 21 are communicated with; Upper die and lower die are through the internal thread on the inwall that is arranged on annular lip 23 24, be spirally connected with external thread 13 on the outer wall that is arranged on patrix base stage 12, and patrix 1 and counterdie 2 are through the O-ring seal sealing.
Need to prove that in the present embodiment, the O-ring seal of employing is a rubber ring, and be arranged at respectively in two grooves of upper die and lower die, its role is to, between the die wall, influence the demoulding about the epoxy resin mixed liquor is penetrated into when avoiding casting.In order to arrive identical purpose, it will be understood by those skilled in the art that and only on patrix or counterdie, to open a groove, plug sealing ring in the groove; Perhaps all recessings of upper die and lower die, only therein in groove plug protrude from groove, and with the O-ring seal of another one groove fit.
In the present embodiment, the outer wall of first die cavity 11 and second die cavity 21 all is square column type, so that the taking of mould; But for the ease of being spirally connected of patrix 1 and counterdie 2, therefore, in patrix 1 lower end, the end with counterdie 2 fastens is provided with a columniform patrix base 12, simultaneously, in the upper end of counterdie 2 annular lip 23 is set.Patrix 1 adopts when fastening with counterdie 2 and is spirally connected, and has both made things convenient for patrix 1 to be connected with the firm of counterdie 2, can metallographic observation sample elder generation deviate from from counterdie 2 through screwing out the mode of patrix 1 after making the sample casting solidify again; Concrete, during the demoulding, the demoulding of spiral shell die sinking tool, because the die cavity of counterdie 2 is cylindrical or the rounding taper type, sample is deviate from counterdie 2 because of rotation; The die cavity of patrix 1 is a square cone, therefore, keeps static, raps with hammer then sample is deviate to big mouthful of place by the osculum of square frustum, or with pulling the taking-up mould, has made things convenient for the demoulding greatly.
Need to prove that also in the present embodiment, upper and lower mould all adopts PP or PE or PTEE to process.Since the bounding force of PP, PE, PTEE and resin a little less than, therefore, can extremely be convenient to the demoulding with the mould that these materials are made.
Adopt the device of the casting metallographic observation sample of present embodiment, the method that metallographic sample is handled comprises:
A. distinguish coating lubricating oil at the inwall of first die cavity and second die cavity;
B. with the sightingpiston of metallographic observation sample towards the bottom, be positioned in the counterdie, then upper die and lower die are fastened;
The casting liquid that C. will prepare is cast to first die cavity from the casting gate of patrix;
D. leave standstill curing and demolding.
In the casing process of present embodiment, casting liquid is the epoxy resin mixed liquor, and preferred, the epoxy resin mixed liquor comprises epoxy resin and hardening agent, epoxy resin: the mass ratio of hardening agent is 2-5: 0.5-2.
Above content is to combine concrete embodiment to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
