Fig. 2 is the utility model test piece mould assembled state structural schematic diagram.
Fig. 3 is the left view of Fig. 2.
Fig. 4 is that the utility model test specimen demoulds status architecture schematic diagram.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As Figure 1-Figure 4, a kind of assisting demolding device of concrete splitting tensile test piece, including pedestal 1, upper press mechanism
And press mechanism, press mechanism include the top pillar 2 that two be fixed on pedestal 1 are vertically arranged, existing test piece mould is by growing
Square frame 3, the top plate 4 being arranged at the top of rectangle framework and the bottom plate 5 that rectangle framework bottom is arranged in are constituted, top plate 4
With bottom plate 5 with the inner wall sliding contact of rectangle framework 3, bottom plate 5 is placed on two top pillars 2 by when demoulding.In two on pedestal 1
A top pillar two sides are symmetrically fixed with two slide bars being vertically arranged 6, and spring 7, the lower end of spring 7 and pedestal 1 are arranged on slide bar 6
It is connected.Upper press mechanism includes two support plates 8 being vertically arranged for being symmetricly set on two two upper sides of top pillar, two support plates
It is separately fixed on the two sidewalls of test piece mould, is fixed with transverse slat 9 between two support plate tops, it is mutually separate in two support plates
Side wall on be symmetrically fixed with slide plate 10, the slide opening being slidably matched with ipsilateral slide bar 6 is offered on slide plate 10, slide plate 10 passes through
Slide opening can be slided up and down along slide bar 6, and the upper end of spring 7 and ipsilateral slide plate are connected, and support plate 8 can be in vertical direction by spring
It moves up and down.
The top of two top pillars is fixed with the push plate 11 of lateral arrangement, and the bottom plate 5 of test piece mould is placed in push plate when demoulding
On 11, such bottom slab stress is more uniform, so that the demoulding of test specimen 13 is more smooth, test specimen is avoided to damage.
Adjacent sidewall bottom offers the card slot 12 for being stuck on test piece mould side wall in two support plates, and two
Support plate is stuck by card slot 12 with test piece mould, and such test piece mould handling are very convenient.
The length of top pillar is greater than the thickness of test piece mould, in this way so that top pillar can be complete from test piece mould by test specimen 13
It releases, so that test specimen demoulding is complete.
Support plate 8 from test piece mould top surface to transverse slat between length be greater than test specimen 13 thickness, such test piece mould top
Face accommodates test specimen to sufficiently large space is just had between transverse slat, so that test specimen is completely out from test piece mould, while
It takes out and removes from test piece mould convenient for test specimen.
The length of slide bar 6 is greater than the length of top pillar 2, and the natural length of spring 7 is greater than the length of top pillar 2, the nature of spring 7
Length be less than slide bar 6 length, spring by elastic force drive support plate be located at top pillar top so that it is convenient to test piece mould assembly,
Slide plate is also prevented from simultaneously to be detached from from slide bar, in order to avoid repeat installation slide plate.
When the utility model is specifically used, the bottom plate 5 of test piece mould is placed in the push plate 11 of two top pillar upper ends, then
Two support plates 8 are stuck on the two sidewalls of rectangle framework 3 of test piece mould, whole device is then put into press machine again
On workbench, the pressing plate of press machine is located at the top of transverse slat, then controls press machine at the uniform velocity applied force, the pressing plate of press machine with
Transverse slat contact, the workbench and base contacts of press machine, by the extruding of press machine at the uniform velocity, transverse slat 9 drives support plate 8 downward
Mobile, support plate 8 drives the rectangle framework 3 of test piece mould to move down, the bottom plate 5 and top plate 4 and test specimen 13 of test piece mould
Rectangle framework 3 relative to part mold moves up, and test specimen 13 is just released from the rectangle framework of test piece mould 3, simultaneously
Slide plate 10 can be moved down with support plate 8, and spring 7 gradually can generate elastic force by compression, until test specimen 13 is from test piece mould
It is completely out in rectangle framework 3, then test specimen 13 is removed, then control the pressing plate of press machine and move up withdrawal, support plate 8
Reset is moved up under the elastic force of spring, can proceed with next test specimen stripping operation, operation is very easy, time saving and energy saving.
