Description
Technical field
The utility model relates to the specimen molding die trials of cement or other shot cementitious material ruggedness tests, more specifically
It says, it is related to a kind of cement mortar specimen molding pneumatic jack die trial.
Background technique
" cement mortar tryout " JC/T726-2005 of National Development and Reform Committee's publication, is the system of Present Cement glue sand specimen molding
Make standard.Die trial including bottom plate 11, end plate 12, partition 13 with clamp device 4 and positioning pin 5 as shown in figure 4, be composed, group
Dress method is that two end plates discrete left and right sides, horizontal be inserted between the end plate of left and right of four baffle intervals on bottom plate are formed three
A die cavity, one partition of avris are resisted against on positioning pin, and screwing the clamp device on the outside of end plate, to form die trial integrally firm
Three joint-trial moulds.It is sealed at end plate, partition and contacts baseplate with butter coating film, in end plate, partition and bottom plate
Side brushing thin film model oil or machine oil play buffer action.Cement mortar tryout is fixed on dedicated lever shake table,
The cement mortar wet feed being stirred is poured into die trial, vibration moulding is put into standard curing box and conserves.Standard curing diel
It is taken out from case afterwards, unclamps fixed screw, touched two end plates and be allowed to separate with partition, test specimen and bottom plate, then touch each partition to make
Separated with test specimen and bottom plate, take out test specimen.
This die trial production test specimen has the disadvantage in that 1, end plate, partition fragment assembling work efficiency are low, and end plate and baffle contacts
Hold easily-deformable influence specimen size.2, it is struck respectively when demoulding and unloads end plate and partition work efficiency is low, and to support the time short because marking, tap vibration
It is also easy to produce the breakage of test specimen end, inside crackle (especially low-intensity test specimen), reduces later period test piece intensity and examine numerical value.
At present in concrete, mortar specimen, also there is pneumatic jack die trial, only opens up suction nozzle air inlet top in die trial bottom
It rises, unusable on cement mortar tryout, because cement mortar is in standard curing only diel demoulding, intensity is very
Low, test specimen bottom is contacted with the regional area of suction nozzle, can be due to internal stress unevenness for low intensive cement mortar test specimen
Generate internal fissure.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of cement to solve the above problems
Glue sand specimen molding pneumatic jack die trial, assembly and disassembly die worker imitate height, and without coating sealing butter, demoulding is shockproof, and pneumatic jack takes out test specimen, guarantor
Demonstrate,proved test specimen without whole property.
To achieve the above object, the utility model provides following technical solution:
Cement mortar specimen molding pneumatic jack die trial, including integral structure triple-cavity mold box, backing board and fastening bolt, the mould
Box end plate and interval vertical that by bottom plate, on bottom plate, both sides are stood vertically be erected on bottom plate, both ends respectively with both sides end plate
The partition of connection forms, and cavity forms three die cavitys side by side, hanging one and bottom wall shape face above each die cavity bottom wall between partition
The equivalent backing board of product, forms air cavity between backing board and die cavity bottom wall, open up and run through on the partition of three pieces of backing boards and diaphragm capsule
Lockhole, fastening bolt are installed in lockhole, and backing board and diaphragm capsule are fastened together, and offer air inlet respectively on each die cavity bottom wall
Hole, air inlet is interior to install gas nozzle external gas source.
It is that the air inlet is located at the center of each die cavity bottom wall that the utility model, which is further improved scheme,.Between two parties
Stomata is arranged in position, when air inlet upwards top lift it is steady.
The further improvement project of the utility model is that the lockhole spacing simultaneously sets two rows, and fastening bolt installs it respectively
Middle locking.Double locking connection is more firm.
The further improvement project of the utility model is that the diaphragm capsule two sides of the bottom are equipped with the stabilizer blade of one.Two sides stabilizer blade
Setting makes to form cavity below diaphragm capsule, convenient for connection gas source.
The utility model compared with prior art, has the advantage that
The diaphragm capsule of this die trial is structure as a whole, only need to be by collet instead of the assembling of the partition of former die trial, end plate and bottom plate
Plate and diaphragm capsule are locked, and when demoulding first removes the fastening bolt in lockhole, then respectively from air inlet to gas interacvity air-filling,
Forming face stress jacks backing board and test specimen, realizes that four peripheral wall of test specimen is separated with die cavity, and last left-hand thread diaphragm capsule takes out test specimen.This
Utility model assembles and disassembles die worker and imitates high, and without coating sealing butter, demoulding is shockproof, ensure that test specimen without whole property.

Fig. 1 is the utility model top view；
Fig. 2 is the A-A cross-sectional view of Fig. 1；
Fig. 3 is the B-B cross-sectional view of Fig. 1.
Fig. 4 is former assembly type die trial structural schematic diagram.
Specific embodiment
As shown in Figure 1 to Figure 3, the utility model includes integral structure triple-cavity mold box 1, backing board 2 and fastening bolt 3, institute
Diaphragm capsule 1 is stated by bottom plate 11, the end plate 12 and interval vertical that both sides are stood vertically on bottom plate be erected on bottom plate, both ends difference
It is formed with the partition 13 of both sides end plate connection, cavity forms three die cavity 14 side by side between partition, hangs above each 14 bottom wall of die cavity
Fill a backing board 2 being equal with bottom wall shape area, between backing board and die cavity bottom wall formed air cavity 15, three pieces of backing boards 2 and
It is opened up on the partition 13 of diaphragm capsule through lockhole 16,16 spacing of lockhole simultaneously sets two rows, and two fastening bolts 3 are installed on two rows of locks respectively
In hole 16, backing board 2 and diaphragm capsule 1 are fastened together, 1 two sides of the bottom of diaphragm capsule are equipped with the stabilizer blade 18 of one, diaphragm capsule lower section
Cavity is formed, air inlet 17 is offered on each 14 bottom wall central position of die cavity respectively, 6 external gas of gas nozzle is installed in air inlet 17
Source.
Specimen molding operating process:
Backing board is aligned with the lockhole on the partition of diaphragm capsule first, fastening bolt is installed and is wherein locked, at this time die trial knot
Structure is firm, prevents backing board from secondary shake occurring in the vibration moulding in later period.Then in backing board upper surface and the mould of diaphragm capsule
Four peripheral wall brushing thin film model oil of chamber or machine oil, which are fixed on dedicated lever shake table, the water that will be stirred
Earth rubber sand wet feed pours into the die cavity of die trial, and vibration moulding is put into standard curing box and conserves.From case after standard curing diel
Middle taking-up, removes fastening bolt, and external gas source, entire jacking backing board and examination upwardly are distinguished in the bottom inflow hole of each die cavity
Part, test specimen peripheral wall are separated with die cavity peripheral wall, not will form the point contact of gas and test specimen and are destroyed test specimen, then that entire die trial is anti-
Button, then test specimen all takes out.
