Abstract
The utility model provides a leak protection decrment plastics examination mould which adopts arc spheroid form to move the cushion, and when the ground paste was built and is shaken, removal cushion and the combination of cushion draw -in groove were closely knit, can prevent effectively that the thick liquid from spilling. During the drawing of patterns, insert drawing of patterns hole with air pump spray gun head, the high pressure draught removes cushion promotion mortar or concrete sample and carries out the drawing of patterns on acting on the removal cushion. For ordinary drawing of patterns method, the sample lifting surface area is big, has avoided damage and the destruction of drawing of patterns process to the sample. The cushion size is less than the inside cavity size of examination mould, lays and take out easy convenience to avoided the damage of full -scale cushion to trying the mould curb plate, sample shaping effect is better.
Description
Technical field
The utility model belongs to testing equipment field, is specifically related to a kind of bituminous concrete, cement concrete or sand-cement slurry and builds shaping test die trial.
Background technology
Because it is simple, the advantage of convenient, low cost, what engineering plastics die trial had been widely used in mortar and concrete sample builds forming field.But, because plastics die trial is non-dismountable, more difficult during the shaping rear demoulding of sample in plastics die trial.Way conventional at present adopts air pump spray gun to insert the plastics die trial demoulding hole die trial is released in test block, but during the demoulding, intensity of test block is lower, and the percussive action of high pressure draught easily causes the damage of test block, and then affects the mechanical property of sample.
For this reason, utility model patent CN201420670329.4 discloses the engineering plastics die trial that one " is provided with a liner plate matched with its bottom area at die body intracavity bottom ".But, because its liner plate is a full-scale liner plate matched with die trial bottom area, more difficult when liner plate placement, taking-up die trial, and easily cause the cut of die trial side wall inner surfaces; The appearance of die trial side plate cut, then can cause the hair side phenomenon of test block side.
Utility model content
The defect existed for above-mentioned background technology or deficiency, the purpose of this utility model is to provide a kind of and prevents slip from spilling, prevent knockout course test block from damaging and plastics die trial simple to operate.
The technical solution adopted in the utility model is: the die trial of a kind of leakproof impairment plastics, and this die trial comprises housing (1), cushion block draw-in groove (2), demoulding hole (3), mobile cushion block (4); Described housing (1) is integrated, and the base plate central authorities of housing (1) are reserved with cushion block draw-in groove (2) and demoulding hole (3), and cushion block draw-in groove (2) is through with demoulding hole (3); Described cushion block draw-in groove (2) is spherical groove, and demoulding hole (3) are inverted T-shaped step trough; Mobile cushion block (4) is equal with the shape and size of cushion block draw-in groove (2), and mobile cushion block (4) matches with cushion block draw-in groove (2); Mobile cushion block (4) is installed afterwards and housing (1) forms a regular cavity.
Described mobile cushion block (4) upper surface is a plane, and after it is arranged on cushion block draw-in groove (2), the upper surface of mobile cushion block (4) is concordant with the plate upper surface of housing (1).
Described mobile cushion block (4) is light-weight high-strength material.
The plastic mat thickness of described housing (1) is greater than side plate.
Described cavity geometry is regular square or right cylinder.
The die trial of a kind of leakproof impairment of the utility model plastics, adopt arc sphere-like to move cushion block, when slip is built and shake, mobile cushion block and cushion block draw-in groove combine closely knit, can effectively prevent slurries from spilling.During the demoulding, air pump lance head is inserted demoulding hole, and high pressure draught acts on mobile cushion block, and mobile cushion block promotes mortar or concrete sample carries out the demoulding.For common release method, sample lifting surface area is large, avoids the damage and fracture of knockout course to sample.Cushion block size is less than die trial internal cavities size, lays and take out easy and convenient, thus avoids the damage of full-scale cushion block to die trial side plate, and sample molding effect is better.
Accompanying drawing explanation
Fig. 1 is the utility model sectional view;
In figure: 1, housing, 2, cushion block draw-in groove, 3, demoulding hole, 4, mobile cushion block.
Embodiment
Below in conjunction with accompanying drawing and specific implementation method, the utility model is described in further details.
See Fig. 1, the die trial of the present embodiment is made up of housing (1), cushion block draw-in groove (2), demoulding hole (3) and mobile cushion block (4);
