Still include drawing of patterns barrel, drawing of patterns diameter of drum equals chambers of the heart diameter in the mould barrel. Drawing of patterns barrel body backend sets up a barrel support, drawing of patterns barrel inside is still installed one and is pressed the stick. The utility model discloses add length and the sag of having used cushion control sand stick, can avoid the problem that manual operation polishing precision is low, make convenient operation swift, improved the degree of automation of experimentation, improved the efficiency of experiment. Adopt drawing of patterns barrel and pressed the stick, made the sand stick process of taking out convenient and fast more, improved experimental efficiency.
Description
Technical field
The utility model relates to sand rod producing device, specifically a kind of for making the die device of sand rod.
Background technology
In the testing process of resin coated sand, compression strength, rupture strength need the sand rod of manual manufacture to detect,Make sand rod motion complexity, mainly comprise the glass tube of choosing internal diameter 25mm length 100mm, bottom is sealed with 100 order steel meshesMouthful. Get 50-100 gram of resin coated sand and join in glass tube, vacuumize with compacting after water saturation, vibrations, be placed in 50 DEG CWater bath with thermostatic control 72 hours, broken pipe are got sand rod and are ground. This experimental implementation process complexity, automaticity are lower, impactMany factors, thus experimental data poor accuracy caused, reduce detection efficiency.
On the one hand, take various effective means to reduce the impact of these factors on measurement result; On the other hand, through rationallyDesign, make to make sand rod motion convenient and swift, by the improvement of this two aspect, meeting the desired precision of sand rod withTime, in conjunction with actual working experience, make this device detection method specification, data accurately, testing result good comparability.
Utility model content
It is a kind of for making the die device of sand rod that the purpose of this utility model is to provide, and improved testing result accuracyAnd detection efficiency, make to operate safer easy.
In order to reach above-mentioned purpose, the utility model has adopted following technical scheme, a kind of for making the mould dress of sand rodPut, comprise mould cylindrical shell, described mould cylindrical shell is the tubular column structure that a center cavity axially connects, at two of mould cylindrical shellEnd blocks up and carries out shutoff with tail, and described mould cylindrical shell center cavity is the space that makes sand rod, at sand rod two ends and the stifled medial extremity of tailBetween add at least one cushion block.
Also comprise demoulding cylindrical shell, described demoulding barrel diameter equals mould cylindrical shell center cavity diameter.
Described demoulding cylinder back-end arranges a cylinder stent.
Described demoulding inner barrel is also installed a pressure bar, coordinates sand rod is taken out with demoulding cylindrical shell; Pressure bar diameter is slightly less thanMould cylinder internal diameter,
Described cushion block is solid cylinder, and its diameter is suitable with mould cylinder internal diameter, for controlling the length of sand rod and parallelDegree and sag; The number of the cushion block that adds depends on the length of required sample, and both are directly proportional.
Described tail blocks up between mould cylindrical shell O-ring seal is set.
Compared to prior art, the utlity model has following beneficial effect:
1, adopted stainless steel cylinder to make sand rod, avoided shaking broken shortcoming, improved experiment success rate andEfficiency.
2, add length and the sag of having used cushion block control sand rod, can avoid the problem that manual operation grinding precision is low, makeConvenient to operation, improve the automaticity of experimentation, improve the efficiency of experiment.
3, adopt demoulding cylindrical shell and pressure bar, made to take out sand rod motion more convenient, improved conventional efficient.
Brief description of the drawings
Fig. 1 is of the present utility model a kind of for making the structural representation of die device of sand rod;
Fig. 2 is that demoulding cylindrical shell and pressure bar are at the structure chart that takes out sand rod.
In figure: 1, mould cylindrical shell; 2, cushion block; 3, tail is stifled; 4, O-ring seal; 5, sand rod; 6, pressure bar; 7,Demoulding cylindrical shell; 8, cylinder stent.
Detailed description of the invention
Relevant detailed description of the present utility model and technology contents, coordinate brief description of the drawings as follows, but accompanying drawing only provides referenceWith the use of explanation, be not used for the utility model to be limited.
According to Fig. 1-2, a kind ofly comprise mould cylindrical shell 1 for making the die device of sand rod, described mould cylindrical shell is oneThe tubular column structure that individual center cavity axially connects, carries out shutoff at the two ends of mould cylindrical shell with tail stifled 3, and described tail blocks up and mouldO-ring seal 4 is set between cylindrical shell. Described mould cylindrical shell center cavity is the space that makes sand rod 5, stifled at sand rod two ends and tailBetween medial extremity, add at least one cushion block 2. Also comprise demoulding cylindrical shell, described demoulding barrel diameter equals mould cylindrical shell centerChamber diameter. Described demoulding cylinder back-end arranges a cylinder stent 8. Described demoulding inner barrel is also installed a pressure bar 6,Coordinate with the demoulding cylindrical shell sand rod is taken out. Pressure bar diameter is slightly less than mould cylinder internal diameter, and described cushion block is solid cylinder,Its diameter is slightly less than mould cylinder internal diameter, for controlling length and the depth of parallelism and the sag of sand rod; The number of the cushion block that addsThe length that depends on required sample, both are directly proportional.
Above parts, except cushion rubber, are 304 stainless steels and make.
Mould cylindrical shell 1 is made sand rod for the glass bar before substituting; Described cushion block 2 is for controlling the length of sand rod and putting downRow degree and sag. Described tail stifled 3 is connected with cylindrical shell by screw thread. Described demoulding cylindrical shell 7 is made for handle with pressure bar 6The complete taking-up of sand rod, and the movement of the conveniently stripped cylindrical shell of cylinder stent and placement.
When operation, be first connected with mould cylinder body bottom stifled tail, put cushion block in mould cylindrical shell, more required according to experimentSpecimen length add sand in mould, the stirring that adds water, and put into another piece cushion block, is finally connected with mould top with tail is stifled.After vibrating sieving machine vibrations compacting, then put into constant temperature water bath 72 hours, after water-bath, stifled the tail of both mold ends and cushion block unloaded,The complete taking-up of sand rod, detect its compression strength and rupture strength with corresponding laboratory apparatus with demoulding cylindrical shell. Package unitAutomaticity is higher, and such design operation is convenient, fast, and automaticity is high, greatly improved conventional efficient andAccuracy.
The foregoing is only preferred embodiment of the present utility model, non-in order to limit the scope of the claims of the present utility model, otherUse the equivalence of patent spirit of the present utility model to change, all should all belong to the scope of the claims of the present utility model.
