Description

A kind of concrete test die

Technical field

The utility model relates to construction engineering technical field more particularly to a kind of concrete test dies.

Background technique

Existing concrete test die majority is plastics die trial, and usually there are ventholes for the bottom of die trial, are pouring slurry It is diluter, when mobility is very good, after the completion of being easy to cause slurry to pour, slurry is flowed out from venthole, and blocks venthole, then shadow Ring next demoulding.

In order to avoid the generation of the above problem, in the plastics die trial in use, usually at bottom air vent, with the scraps of paper or Other thin slices shelter from venthole, to prevent slurry from flowing out from breather port, but in this way after slurry solidification, the scraps of paper or thin slice It can be affixed directly on slurry, influence beautiful appearance；Also or, after shaking slurry, may make to starch due to violent vibration The outflow of body impregnated sheets, blocks venthole.Although in addition, there is also some structures for blocking stomata, such as valve is used to block, But structural member is complicated, at high cost.

Utility model content

The purpose of this utility model is to provide a kind of achievable ventholes to block, and structure is simple, easy to operate, closure The good concrete test die of effect.

To achieve the goals above, the utility model provides a kind of concrete test die, which is characterized in that including die trial sheet Body, positioned at die trial body bottom portion and the venthole being connected to die trial chamber body and the closeouts for blocking venthole, Wherein: closeouts include blocking bar and sealing cap, block bar and are fixedly connected with sealing cap；Bar is blocked to be inserted by the outside of die trial ontology Enter, block venthole；After blocking bar insertion venthole, sealing cap is bonded with die trial ontology outer bottom.

Further, it blocks bar and sealing cap is integrally formed.

Further, it is consistent with the hole depth of venthole to block bar bar length.

Further, block bar be polished rod and with venthole clearance fit.

Further, the fit clearance between bar and venthole is blocked between 0.1 millimeter -0.5 millimeter.

Further, blocking bar is threaded rod；The inner wall of venthole is equipped with the internal screw thread to match with threaded rod external screw thread； Bar is blocked to be threadedly coupled with venthole.

Further, sealing cap is multiedge cylinder.

Further, it is logical to be additionally provided with the air inlet for connecting pump-up device being connected to venthole for the bottom of die trial ontology Road.

A kind of concrete test die of the utility model, has the advantages that

1, the concrete test die of the utility model blocks venthole using closeouts, to can effectively avoid slurry by leading to Stomata outflow, plugging effect is good, and closeouts structure is simple, at low cost；In addition, closure movement is simple, quick.

2, the closure bar of the closeouts of the utility model be polished rod, and with venthole clearance fit, convenient for block bar it is quick It is inserted into venthole.

3, the closure bar bar length of the closeouts of the utility model is consistent with venthole hole depth, to effectively avoid blocking bar mistake Deep insertion venthole influences molded part appearance.

4, the closure bar of the closeouts of the utility model is threadedly coupled with venthole, and plugging effect is more preferable, and blocks bar It screws in easy to operate with back-out.

5, the sealing cap of the closeouts of the utility model uses multiedge cylinder, convenient for being screwed in, being screwed out by closure bar by sealing cap, Venthole is extracted in insertion.

6, the concrete test die of the utility model realizes effective closure of venthole, and closeouts structure is simple, purchases into This is low, and plugging operations are simple.

Specific embodiment

Below in conjunction with the attached drawing in the utility model, to the technical scheme in the embodiment of the utility model carry out it is clear, Complete description, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole implementation Example.Based on the embodiments of the present invention, those skilled in the art is without making creative work All other embodiment obtained, belongs to the protection scope of the utility model.

As shown in Figure 1 and Figure 2, a kind of concrete test die of the utility model embodiment, including die trial ontology 1, be located at die trial 1 bottom of ontology and the venthole 2 being connected to 1 inner cavity of die trial ontology and the closeouts 3 for blocking venthole 2, in which: Closeouts 3 include blocking bar 31 and sealing cap 32, block bar 31 and are fixedly connected with sealing cap 32；Bar 31 is blocked by die trial ontology 1 Outside insertion blocks venthole 2；After blocking the insertion venthole 2 of bar 31, sealing cap 32 is bonded with 1 outer bottom of die trial ontology.

Specifically, blocking the size of bar 31 should match with the structure size of venthole 2, should meet logical when blocking the insertion of bar 31 Venthole 2 can be blocked after stomata 2, and the slurry of 1 inner cavity of die trial ontology is avoided to be flowed out by venthole 2.In addition, it is long to block 31 bar of bar Hole depth with venthole 2 should be consistent, to effectively avoid blocking the too deep insertion venthole 2 of bar 31 influence molded part appearance.Envelope Blocked shot 31 can be fixedly connected with sealing cap 32 by welding manner, it is preferred that block bar 31 and sealing cap 32 is integrally formed.

As a kind of enforceable embodiment, block bar 31 be polished rod and with 2 clearance fit of venthole, certainly between cooperation Gap is not answered excessive, and slurry on the one hand should be avoided and flowed out by fit clearance, and on the other hand smoothly insertion is logical guaranteeing to block bar 31 Under the premise of stomata 2, using 2 hole wall of venthole and blocking the friction between 31 bar wall of bar prevents closure bar 31 from being taken off by venthole 2 Out.Optionally, the fit clearance between bar 31 and venthole 2 is blocked between 0.1 millimeter -0.5 millimeter, certainly, this field skill Art personnel can also specifically determine according to the actual situation.

As a preferred embodiment, blocking bar 31 is threaded rod；The inner wall of venthole 2 is equipped with and spiral shell outside threaded rod The internal screw thread that line matches；Bar 31 is blocked to be threadedly coupled with venthole 2.On the one hand blocking bar 31 can guarantee to lead to using threaded rod The plugging effect of stomata 2, on the other hand closure bar 31 is easy to operate by being threaded into, screwing out venthole 2；In addition, using spiral shell Its connection reliability of line connection type is further promoted.

Further, sealing cap 32 is multiedge cylinder.Sealing cap 32 uses multiedge cylinder, convenient for that will block bar 31 by sealing cap 32 It screws in, screw out, insertion or extraction venthole 2, the exploitativeness of operation are further promoted.

As shown in Figure 1, the bottom of die trial ontology 1 is also set in some embodiments of the concrete test die of the utility model Be equipped be connected to venthole 2 for connecting the inlet channel 4 of pump-up device, so that facilitating inflator, air gun etc. inflates dress The connection installation set.

The utility model is further described by specific embodiment above, it should be understood that, have here The description of body, should not be construed as the restriction to the spirit and scope of the utility model, and one of ordinary skilled in the art is readding The various modifications made after reader specification to above-described embodiment belong to the range that the utility model is protected.
