Abstract

The utility model relates to die casting hollow plate (tube) material which uses composite slurry of chlorine, oxygen and magnesium and adopts rubber or plastics as materials, which is characterized in that one end of a die of a pipe fitting with a smaller casting tube diameter is provided with a flaring head. A die tube of a pipe fitting with a larger casting tube diameter is provided with a straight port in which a rubber strip is pressed. One end of the die is provided with a flange head with a rubber ring. The problem of die disconnecting is solved smoothly, and the composite slurry is widely used. Prefabricated hollow plate (tube) material can replace entity building materials, such as bricks, tiles, concrete, etc. The weight of components are lightened and the consumption of the materials is reduced.

Description

Mould for hollow plate and pipe materials cast with composite paste

The utility model is with the mould of chlorine oxygen magnesium composite mortar cast cored slab (pipe) material, uses the prefabricated cored slab of mould of the present utility model (pipe) material, can be used for industry and civil buildings, also is adapted to industrial departments such as farmland spray irrigation system, metallurgy and environmental protection.

Existing chlorine oxygen magnesium composite mortar placing, because of slurry has flowability, must be in mould curing molding, only can be processed into solid materials such as wood particle board, floor tile plate, thistle tile, the processing cored slab, use stereoplasm tube then can't remove during tubing, thereby limited the extensive use of this composite mortar.

It is a kind of under the situation of damaged member not that the purpose of this utility model is to provide, remove the mould of pore inner membrance smoothly, precast hollow sheet material, tubing, this prefabricated components can replace brick and tile, concrete and reinforced concrete building material, alleviate the weight of member, reduce supplies consumption.

The key technology of composite mortar cast cored slab (pipe) material is the making of mould.The pipe fitting that internal diameter is less can be made tubular die with elastomeric material, for guaranteeing the connection between the pipe fitting, at a bonding enlarging head of pipe fitting.In order to keep the axiality of pipe fitting, can select for use an external diameter to be slightly less than in the steel pipe or plastic conduit cover progressive die pipe of rubber pattern bore, outer formwork can require to make according to type quality, and glacing flatness requires low, can select the polyester film involucrum for use; Glacing flatness requires high, and the hard pipe fitting that then can select for use bore to equate with the made pipe fittings external diameter is made the mould pipe, and being cut into two and half gardens pipe from center line promptly is that external mold enlarging head is also made of similar way.

The pipe fitting that caliber is bigger, the making of internal mold can be chosen a hard and the flexible pipe of tool, cuts mouth always at arbitrary position along longitudinal direction, is pressed into a rubber bar in the straight mouth, its role is to expand the garden of opening and manage diameter, after composite mortar solidifies, take out rubber hold-down strip, tube wall shrinks and the demoulding, connection for ease of pipe, regulate an enlarging diameter and be convenient to the demoulding that is shaped, be equipped with of pipe the band rubber ring flange head the inner mold of large-size pipe, outer formwork is made by the said way in front.

Precast hollow sheet material can be made garden shape or square porose rubber internal mold pipe according to the geometry requirement of sheet material through hole.

After above-mentioned several mould has been arranged, just can make cored slab (pipe) material of all size model, filling is through bonding sawdust in the through hole of hollow plate, and pulverized foamed plastic just can be made into sandwich sheet material, utilizes this technology also can make the light shed member.

The mould that the utility model provides, the difficulty of moulding/demoulding in when having solved the fibreglass reinforced magnesium oxychloride composite mortar and making hollow construction material, because mould is simple, operation is few, operating personnel grasp easily, improved poring rate, alleviated labour intensity, usually remove 30 seconds of internal mold less than of 3 meters long pipe fittingses, composite mortar cored slab (pipe) material with this Mold Making, surface lining with mosaic and so on uses, the interior wall and the outer body of wall material that can be used for skyscraper, its wall weight alleviates 80-85% than brick and reinforced concrete, and the body of wall area occupied is reduced, and increases the effective area in house.Composite pipe is made draining or aqueduct at urban construction, aspect such as agricultural, and its cost only is 50% of a steel pipe.The set member of this material is used to make the hot house greenhouse, not only has the economic benefit that reduces cost, and service life is more much longer than steel pipe, non-corrosive, and weatherability, anti-corrosion property can be fine.

Now contrast the making of description of drawings chlorine oxygen magnesium composite mortar cored slab (pipe) material.

Make hollow plate, at first be ready to chlorine oxygen magnesium composite mortar (1), on a level and smooth workbench, complete polyester film, choose the angle steel of certain model by the sheet material thickness requirement and make framework, tent is made with plank in two ends, is poured on the polyester film slurry (1) also floating, spread as requested to certain thickness, on slurry (1), repave glass cloth, floating, go up second layer slurry (1) again, floating, square (hole, garden or square hole) rubber internal mold pipe (2) is coated grease, and equidistant pendulum and at one end leaves certain-length in framework, so that take out the pipe demoulding, with pipe nipple glass suede mix slurry (1), insert the space between the mould pipe, and leveling, repave one deck (or multilayer) glass cloth (3) then, and it is floating to spread slurry (1), makes it consistent with frame thickness, scrapes redundant sizing agent (1), seal two with the plate plug, cover polyester film earlier, cover steel plate, casting complete again.As process multilayer, then press aforesaid operations and continue upwards superposition construction.

Through one period hardening time, reaching early strength is collapsible die, removes earlier outer mold framework during form removal, holds rubber internal mold pipe (2) one ends then and firmly outwards pulls out internal mold pipe (2), uses metal sawing limit shaping at last, then gets section bar (Fig. 2).

Make tubing, prepare assembly jig shown in Figure 3 (minor diameter tubing is selected the rubber internal mold pipe (5) of band enlarging head (4) shown in Figure 4 for use), on polyester film, spread two-layer glass cloth (3) and slurry (1), operate like that when making by sheet material, the winding mold pipe packs tightly then, and skin is used the polyester film involucrum, will wrap in the outer and clamping of injection body with two and half garden shape pipe dies of shape, flow fixing the shaping with slurry-free (1).Again injection body is placed on centrifugal rotation in the rotating cylinder by driven by motor, slurry (1) is evenly distributed, eliminate the appearance bubble; Get final product the demoulding after solidifying certain hour.During the demoulding, remove earlier external mold, remove flange (6) enlarging rubber ring (7) again, draw rubber strip (8) again, at this moment the mould pipe shrinks, and takes out mould pipe (9).

In the through hole of hollow plate, fill light filler (10) (foam plastic, plastic foam, saw foam etc.) with slurry (1) mix, solidify the back sandwich sheet material.
