Abstract
A kind of inflatable rubber plug facilitating pore-forming, be made up of support bar (1) and the double-layer circular rubber strip (2) wrapped tightly on support bar (1), the side seals of double-layer circular rubber strip (2), space between double-layer circular rubber strip (2) is communicated in air pump (5) by the wireway (3) be fixed on outer layer rubber, wireway (3) is provided with valve (4), the utility model structure is simple, cheap, easy to use, loose core time saving and energy saving effective when producing building materials with holes, yield rate improves greatly.
Description
Technical field
The utility model relates to the instrument of loosing core during a kind of light building material pore-forming, specifically a kind of inflatable rubber plug facilitating pore-forming.
Background technology
At present, the class construction materials such as existing indoor partition panel, building-block, for alleviating own wt, usually hollow is made in the centre of building materials when making, general making step is: in proportion cement, additive and water are stirred into uniform slurry, inject mould, be placed with metal mandrel (can releasing agent be coated) in mould, after cement slurry solidifies, then metal mandrel is ejected, pull out or rotate mould, consequently require great effort time-consuming, product cracky.Find through patent searching document, someone proposes the forming method utilizing inflating rubber pipe alternative metals plug, but this method also has weak point: inflating rubber pipe there will be the phenomenon of middle sagging (being bent downwardly) after putting into mould; When inflating in rubber tube, need whole pipe to be full of pressure air, pipe just can be made to be in swelling state.A kind ofly be filled with little air if designed rubber tube just can be made to expand and not have sagging plug, just can speed production efficiency, and greatly improve yield rate.
Summary of the invention
The utility model is just to provide a kind of inflatable rubber plug facilitating pore-forming, and the air that only need be filled with seldom amount just can make the phenomenon bending (sagging) when rubber swelling, use, and loose core time saving and energy saving, simple and convenient, yield rate improves greatly.
The utility model is achieved in that a kind of inflatable rubber plug facilitating pore-forming, be made up of support bar (1) and the double-layer circular rubber strip (2) wrapped tightly on support bar (1), it is characterized in that, the side seals of double-layer circular rubber strip (2), space between double-layer circular rubber strip (2) is communicated in air pump (5) by the wireway (3) be fixed on outer layer rubber, wireway (3) is provided with valve (4).Air pump (5) can be any one of air compressor machine, automobile-used small air pump, treadle air pump or manual inflator.
The utility model structure is simple, cheap, easy to use, time saving and energy saving effective when producing building materials with holes.

Detailed description of the invention
Below in conjunction with accompanying drawing 1,2,3, the utility model is elaborated.
A kind of inflatable rubber plug facilitating pore-forming, be made up of support bar (1) and the double-layer circular rubber strip (2) wrapped tightly on support bar (1), the side seals of double-layer circular rubber strip (2), space between double-layer circular rubber strip (2) is communicated in air pump (5) by the wireway (3) be fixed on outer layer rubber, wireway (3) is provided with valve (4).Because the space between double-layer circular rubber strip (2) is very little, come (due to the supporting role of support bar, rubber strip can only be outer outwards expansion) so air pump (5) is easy to double-layer circular rubber strip (2) rising.Because space is little, can use small air pump, treadle air pump or manual cartridge inflation completely, it is any bending that support bar (1) can not make inflatable rubber plug produce, and more easily looses core.
During use, the utility model is put into mould, be filled with appropriate air, valve-off (4), in proportion cement, additive and water are stirred into uniform slurry, inject mould, after cement slurry solidifies, open valve (4), deflate, double-layer circular rubber strip (2) shrinks, and the utility model nature and set cement slurry (6) are peeled off, easily can extract the utility model out, obtain complete light building material product.
If production porous articles, multiple the utility model is together in parallel, shares an air pump.
Claims (2)
1. one kind facilitates the inflatable rubber plug of pore-forming, be made up of support bar (1) and the double-layer circular rubber strip (2) wrapped tightly on support bar (1), it is characterized in that, the side seals of double-layer circular rubber strip (2), space between double-layer circular rubber strip (2) is communicated in air pump (5) by the wireway (3) be fixed on outer layer rubber, wireway (3) is provided with valve (4).
2. a kind of inflatable rubber plug facilitating pore-forming according to claim 1, is characterized in that air pump (5) can be any one of air compressor machine, automobile-used small air pump, treadle air pump or manual inflator.
