Description

Concrete sample assembling die and hand-stripping device

Technical field

This utility model relates to a kind of mould and stripper apparatus, particularly relates to a kind of concrete sample assembling die and hand-stripping device.

Background technology

In the fields such as current building, road and bridge, concrete test research, all it be unable to do without the making of concrete sample.In order to obtain the concrete sample of high-quality, during making concrete sample, in addition to the concrete that mixing is good, the mould that test specimen uses is the most particularly significant with release method, but, used concrete sample mould is not the most perfect with release method.First for mould, now it mostly is steel assembling die or mould of plastics with concrete sample mould, comes with some shortcomings during use: first, when using steel assembling die, need mould is carried out more complicated combination and fractionation, waste time and energy；Second, when using mould of plastics, owing to striking time is late, releasing agent is smeared uneven, cross and shake or the reason such as bottom air-hole blockage, gas leakage can cause demoulding difficulty, and when the larger-size prism test specimen of shape such as 100mm × 100mm × 400mm is carried out the demoulding, it may appear that gases at high pressure only make test specimen break away from moulds very fraction, it is still necessary to the situation of laborious hand ejection；3rd, the use process of mould of plastics has die deformation phenomenon to be occurred, now can cause shaping test block and together deform, and both can cause test specimen demoulding difficulty, the mechanical property result of test test specimen can have been produced impact again.Then, for some current test specimen release methods and stripper apparatus, there is the handy concrete test block stripper Shortcomings the most in some aspects that some are relevant, such as: have a kind of dependence manual operation jack, the pressure effect utilizing jack realizes the hand-stripping device of the test specimen demoulding, in use being required for each test specimen and carry out repeatedly manual depression jack depression bar, repetitive operation number of times is more.The release method also having a kind of box hand-stripping device including knockout pin to use is the handle by shaking casing side, drive knockout pin moves up, promote the test specimen demoulding, so operate and there will be 2 problems: first, knockout pin is relied on to be ejected by test specimen, knockout pin is little with test specimen contact area, contact stress can be caused to concentrate, damage test specimen；Second, when cohesive force between test specimen and mould is the biggest, swinging handle difficulty.

Detailed description of the invention

With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.

In conjunction with Fig. 1 to Fig. 3, a kind of assembling die of the present utility model, this mould includes the outside unitary mould 1 of steel, plastics slidably base plate 2, when pouring test specimen, is that 10mm thickness plastics slidably base plate 2 is positioned by boss in the bottom by outside unitary mould 1.Hand-stripping device, this device includes rubber mat plate 3, support column 4, bearing support 5, hold-down devices 6, little gear 7, gear wheel 8, scalable depression bar 9, base 10, trip 11, preformed hole position 12, Large Gear Shaft 13, pinion shaft 14 and pressing plate 15.Rubber mat plate 3 is inlayed at support column 4 top and support column is uprightly loaded on base 10, issuable vibrations when can absorb the demoulding by rubber mat plate 3, and strengthen the friction between support column 4 and mould contact surface, by bearing support 5 by pressing down section part 6, little gear 7, gear wheel 8 gear shaft 13, pinion shaft 14 is combined, form linkage, after linkage, 8 need of gear wheel carry out part-circular periphery and rotate to produce and be enough displaced through little gear-tooth bar and pass to the pressing plate 15 of pressing down section part 6, for test specimen and mould generation relative movement, scalable depression bar 9 is coupled with gear wheel 8, trip 11 is utilized to position holding steel plate 5 with the preformed hole position 12 on base 10, each preformed hole position 12 conllinear on base 10.In the drawings, mold bottom slidably base plate 2 promotes test specimen externally unitary mould 1 inwall to slide, test block produces relative movement with mould, to treat that demoulding test specimen is placed in rubber mat plate 3 upper surface, reasonable preformed hole position 12 is selected to make pressing down section part 6 to proper level position, pressure pressing down section part 6 makes boss be fully contacted with assembling die 1 lower limb, to be applicable to the different size concrete sample demoulding.

During use, the mould and test specimen for the treatment of form removal are placed on support column 4, different size according to test specimen selects suitably preformed hole position 12 on base 10 to be fully contacted to test specimen with regulation pressing down section part 6, regulate scalable depression bar 9 to appropriate length, pressure depression bar 9, the downforce of depression bar 9 passes to pressing down section part 6 by gear, and outside unitary mould 1 pushed down by the pressing plate of pressing down section part, make mould depart from test specimen, complete the demoulding.

It needs to be noted, when when demoulding test specimen is larger-size prism test specimen, except needing to regulate the horizontal level of both sides pressing down section part 6, also needing to be further added by the quantity of support column 4, its riding position is determined jointly by position and the sample dimensions of trip 11 with the preformed hole position 12 on base 10 equally.When demoulding test specimen is cylinder test specimen, the horizontal level of regulation pressing down section part 6 to ensure that with mold bottom protrusion at 4 be fully contacted and can complete the demoulding.

This utility model be the technical scheme is that first, makes a kind of assembling die, is divided into outside integral part and internal activity part, makes mould inside bottom surface jointly can slide straight up along mould inner wall with shaping test specimen, it is achieved the test specimen demoulding.Second, make a kind of hand-stripping device, utilize Manual pressure bar, transmit strength by gear, make mould and shape test specimen generation relative movement.3rd, by regulation pressing down section part and the horizontal level of support column, carry out the demoulding for various sizes of test specimen.4th, inlay rubber mat plate at support column top, absorb vibrations and increase the friction between contact surface, keep stable.

This utility model provides a kind of concrete sample assembling die and supporting hand-stripping device thereof.Assembling die includes the outside unitary mould of steel, and plastics slidably base plate, its kind includes cube, prism and cylinder mold.Its supporting hand-stripping device includes rubber mat plate, support column, bearing support, pressing down section part, little gear, gear wheel, scalable depression bar, base, trip, preformed hole position.On base, the support column of rubber mat plate is inlayed at upright top of installing, the mould pressing down section part of adjustable water mean place it is furnished with in support column both sides conllinear symmetric position, it is that two ends pressing down section part positions by trip and preformed hole position, adapts to the various sizes of concrete sample demoulding.During use, to treat that form removal test specimen is placed on supporting platform between two parties, pressing down section part is fully contacted at mold bottom protrusion, manual depression depression bar, under the power effect of gear transmission, test specimen gets final product and mould separating, this kind of mode can either make test specimen and described mould separating conveniently and efficiently, and test specimen will not cause again damage, use are limited little by place, facilitate the artificial demoulding, improve die trial utilization rate.
