Description
Technical field
The utility model belongs to test mould processing and manufacturing and applied technical field, more particularly to for engineering material mechanics
A kind of self-expanding material consolidation forming die of performance test.
Background technology
Compared with water reacts class polyurethane material, non-aqueous reaction class polyurethane material has stronger self-expanding characteristic.Nothing
Under restrained condition, volume can expand 20 times or more in a few seconds.The basic principle of the technology is by two-component by Grouting Pipe
Polyurethane is injected into precalculated position, quickly forms induration and with volume expansion using the chemical reaction between two-component, realizes
The purpose of filling cavity, solid soil, lifting structure.Since such polyurethane material is two-component performed polymer, polymerisation is not
The participation of live water is needed, is not only suitable for rich water condition, and suitable for anhydrous condition, and reacts the induration of generation to environment
It does not pollute, thus is blocked as the infrastructure anti-seepage reinforcings such as dykes and dams, highway, airfield pavement, prominent water burst, underground piping leakage
Most promising polymer chemistry starches material in being repaired with sedimentation.
Non-aqueous reaction polyurethane material is cementing to medium generation infiltration under expansive force effect, and when performed polymer generation is poly-
After closing reaction, the structure and property of material change, and most apparent is exactly rapid spatial expansion.Expansive force is not only by medium spy
Property influence, and related with many factors such as density of material, slip casting rate, grouting amount and reaction time.It is to utilize mostly at present
The test device or reference other materials test method voluntarily developed carry out mechanical property test to it.It has been reported that
In the preparation studied the density of material with carry out test specimen during mechanical behavior relationship using homemade backpressure device.Its by upper platen,
Steel drum, lower tray composition, upper platen, pressing disc and steel drum are attached by screw thread and realize sealing.Upper platen is equipped with note
Hole and gas vent are starched, induration is ejected using stripper, induration test specimen is cut into predetermined size on fine turning lathe.Mesh
Preceding laboratory test mold more perfect or maturation not yet, existing main problem include：First, injected hole poor sealing.
Very big expansive force can be generated during self-expanding material slip casting, if slip casting hole plug is tight or contact surface sealing of mold component
Not tight, excessive expansive force can fly slurry and mold, seriously endanger the safety of test operator；Second is that existing low-cost die
Has no pressure table.On the one hand, expansion generation in mold can not be learnt when carrying out material different densities and being tested with mechanical relationship
Pressure value；On the other hand, mould inner pressure is difficult to estimate, when demoulding is difficult to accurately take rational safeguard procedures；It is third, solid
The demoulding of knot body test specimen is difficult.Self-expanding material is swift in response, and the most fast several seconds can react, and self-expanding material is foaming
Viscosity is big during molding, and expansive force is strong, and specimen molding rear surface is sticked and dies cavity, and demoulding difficulty is big, easily cause test specimen by
Damage or die deformation.Fourth, induration test specimen cutting error is big.Directly entire test specimen obtained is cut, gained test specimen ruler
Very little and regularity cannot strictly meet requirement of experiment, and surface of test piece integrality is poor, directly affects the accurate of result of the test
Degree and science.Therefore it is the carry out self-expanding material mechanical property test of accurate science, designs the molding of a set of science practicality
Mold has important economic implications.Mold is the necessity for the mechanical property test for carrying out indoor material, and the problem of mold is straight
Connecing influences the quality of shaping test piece, is one of core for testing success or failure.Furthermore a large amount of mold or device do not conform to because of its design
Reason, consumption is very big, and the process-cycle of mold is long.Therefore, scientific design is carried out with improving to various molds according to actual needs,
Prolong the service life, there is important economic implications.
Utility model content

Pattern has, so that mold obtains more extensive performance, ensures test specimen quality, improves conventional efficient, extends mold and uses
Service life.
The utility model is achieved by following technical solution.
A kind of self-expanding material consolidates forming die, is made of cylinder, capping, fixing bracket and tablet, the cylinder
Both ends be respectively arranged with capping, the closure base portion of cylinder lower end is provided with the first tablet, and the surrounding of tablet passes through fixing bracket
It is connect with the second tablet；Be provided through respectively at the top of the capping of the cylinder upper end the second tablet connection pressure gauge pipeline,
Pipeline across the second tablet connection stock inlet, the pipeline across the second tablet connection exhaust outlet, stock inlet pipeline, exhaust outlet pipe
Road is respectively arranged with valve.
A kind of self-expanding material consolidates forming die, and the fixing bracket is screw rod.
A kind of self-expanding material consolidates forming die, and suitable for reading, the lower mouth of the cylinder is respectively arranged with connection capping
Tongue, capping are correspondingly arranged on the groove of connector drum.
A kind of self-expanding material consolidates forming die, and the tablet is provided with screw hole and circular groove, the fixed branch
Erection is equipped with screw rod.
A kind of self-expanding material consolidates forming die, and sealing ring is set in the capping.
Compared with prior art, the utility model has the beneficial effect that：
1st, the utility model can according to mechanical property test require straight forming predetermined size test specimen, be not required to test specimen into
