Abstract
The utility model discloses a sample demoulding device which comprises a working table, a jacking mechanism under the working table, and a test mould frame fixed on the working table, wherein the jacking mechanism comprises a jacking driver and an ejector rod which are connected with each other in a way of transmission; the working table is provided with an ejector rod hole, and the ejector rod passes through the ejector rod hole; the test mould frame comprises an upper mould frame, a lower mould frame and connecting pieces; the upper mould frame and the lower mould frame are respectively fixed with the connecting pieces, and are both horizontal; the distance between the upper mould frame and the lower mould frame is greater than the height of a mould cylinder of a corresponding test mould; the upper mould frame is provided with a circular sample hole; the diameter of the sample hole is greater than the inner diameter of the mould cylinder and smaller than the outer diameter of the mould cylinder; and the lower mould frame is provided with a top hole. When a bottom plate of the test mould is jacked by the ejector rod of the jacking mechanism, the top of the test mould leans against the lower side of the upper mould frame, and a sample can pass through the sample hole of the upper mould frame, so that demoulding of the sample can be completed. Therefore, the sample demoulding device has the characteristics of being reasonable in structure and convenient to operate.
Description
Technical field
The utility model relates to the sample production equipment of compounds such as a kind of cement, pitch, the sample stripper apparatus of compounds such as the cement of more specifically saying so, pitch, dependent territory worker's test apparatus technical field.
Background technology
Be some performances of compounds such as test cement, pitch, after often needing compound made sample by certain requirement, on corresponding test apparatus, sample carried out tests such as compressive strength, shear resistance.The sample of compound such as cement, pitch is generally cylindrical, the die trial of making cylindrical compound sample comprises columnar mould tube, in the mould tube, be provided with circular base plate, base plate is shelved on the bottom of columnar mould tube, put into the compound that needs test at the mould tube, behind the good samples of machinery production such as corresponding compacting or gyratory compaction, sample need be separated with die trial, just sample takes out from die trial, i.e. the demoulding.The useful manual method of the existing demoulding on a round bar, ejects the base top of die trial to sample, still, because being compacting or gyratory compaction, makes compound, the adhesion of sample and die trial can be bigger, and the said method demoulding is difficulty relatively, but also relatively require great effort; The existing demoulding also has by the mould drum outer wall with die trial, with the base plate of lifting bodies such as screw mandrel by die trial, sample is ejected, and, sample is taken out operation inconvenience though this quadrat method can overcome the adhesion of sample and die trial from die trial.
The utility model content
At the problems referred to above, the problem that the utility model quasi-solution is determined provides a kind of stripper apparatus of easy to operate sample.
For addressing the above problem, the utility model has adopted following technical scheme: a kind of stripper apparatus of sample, it comprises work top, the lifting body under work top, is fixed on the die trial frame on the work top, described lifting body comprises jacking driving and the push rod that is in transmission connection, described work top is provided with jogger hole, and described push rod passes jogger hole; Described die trial frame comprises top mold frame, following mould bases and web member, described top mold frame is fixed with web member respectively with following mould bases, described top mold frame all is horizontally disposed with following mould bases, distance between described top mold frame and the following mould bases is greater than the mould tube height of corresponding die trial, described top mold frame is provided with circular sample aperture, the diameter of described sample aperture is greater than the internal diameter of mould tube, less than the external diameter of mould tube, and described mould bases down is provided with apical pore.
It is cylinder or oil cylinder that described jacking drives.
The apical pore wall upper end of described mould bases down is provided with recess, and the diameter of described indent apical pore is greater than the external diameter of the mould tube of die trial.
Adopt such scheme, the stripper apparatus of sample of the present utility model, lifting body under work top, fixing die trial frame on work top, distance between the top mold frame of die trial frame and the following mould bases is greater than the mould tube height of corresponding die trial, so conveniently die trial is put between top mold frame and the following mould bases, because the sample aperture diameter on the top mold frame is greater than the internal diameter of mould tube, external diameter less than the mould tube, like this when the base plate of top die trial on the push rod of lifting body, the die trial top withstands on the downside of top mold frame, and sample can pass the top mold frame sample aperture, just can finish the demoulding of sample, therefore, the stripper apparatus of sample of the present utility model has rational in infrastructure, convenience operation.
Description of drawings
Fig. 1 is the structural representation of the stripper apparatus of the utility model sample;
Fig. 2 is the structural representation of stripper apparatus when putting into die trial;
Fig. 3 is the structural representation of top mold frame.
Among the figure: the 1-work top, the 2-jacking drives, 3-push rod, 4-jogger hole, 5-top mold frame, mould bases under the 6-, 7-web member, 8-sample aperture, 9-apical pore, 10-mould tube, 11-recess.
Embodiment
As shown in Figure 1 and Figure 2, the stripper apparatus of sample of the present utility model, comprise work top 1, at the lifting body under the work top 1, be fixed on the die trial frame on the work top 1, described lifting body comprises that the jacking that is in transmission connection drives 2 and push rod 3.It is cylinder or oil cylinder that described jacking drives 2.
Described work top 1 is provided with jogger hole 4, and described push rod 3 passes jogger hole 4.
Described die trial frame comprises top mold frame 5, following mould bases 6 and web member 7, and described top mold frame 5 is fixing with web member 7 respectively with following mould bases 6.The described web member 7 general pillars that adopt.Described top mold frame 5 all is horizontally disposed with following mould bases 6, distance between described top mold frame 5 and the following mould bases 6 is greater than mould tube 10 height of corresponding die trial, described top mold frame 5 is provided with circular sample aperture 8(referring to Fig. 3), the diameter of described sample aperture 8 is greater than the internal diameter of mould tube 10, less than the external diameter of mould tube 10, and described mould bases 6 down is provided with apical pore 9.The diameter of described apical pore 9 is generally less than the external diameter of the mould tube 10 of die trial, greater than the diameter of push rod 3.
As preferably, be provided with recess 11 on apical pore 9 walls of described mould bases 6 down, the diameter of described recess 11 place's apical pores 9 is greater than the external diameter of the mould tube 10 of die trial.Like this, when making the demoulding, the mould tube 10 of die trial is shelved on recess 11 bottoms, makes the mould tube 10 of die trial relatively stable, is difficult for occurred level and moves.
