The quantity of described the second internal mold is two, wherein, described in first, the second internal mold extend into described external mold framework from the second opening, second described the second internal mold extend into described external mold framework from the 4th opening, described in first, the second internal mold docks mutually with second described the second internal mold, and connects by the base plate of two described the second internal molds; The distance on the top of two described the second internal mold side plates is more than or equal to the spacing between described the second template and described the 5th template, so that two described the second internal molds can form identically with external mold framework, does not misplace.
Further, described the first external mold becomes docking, like this easy accessibility with described the second external mold by bolt shape.For example, in the first template 11 of the first external mold 1 and the 3rd template 13, there is flange, flange is provided with screw 18, in the 4th template 21 of the second external mold and the 6th template 23, there is flange, flange is provided with screw 28, during connection, by bolt, passes screw 18 and screw 28, just can connect easily the flange in flange and the 4th template 21 and the 6th template 23 that has of the first template 11 and the 3rd template 13, and dismounting is also all outside the first external mold and described the second external mold, very convenient.The first external mold and described the second external mold leave mother-son groove at mould seam crossing, are convenient to two side mold location.
Further, described the first opening is different with the shape of the second opening, to obtain the cable passage of different size.
Further, described the second template 12 and described the 5th template 22 respectively with the top clamping of described the first internal mold side plate.As Fig. 1 and Fig. 4, the second template 12 is provided with tenon 17, the five templates 22 and is provided with groove 27, for the top clamping with described the first internal mold side plate, to realize the location between interior external mold.In like manner, described the second template and described the 5th template respectively with the top clamping of described the second internal mold side plate.
Further, described in first, the first internal mold is bolted mutual docking with second described the first internal mold.Described in first, the second internal mold is bolted mutual docking with second described the second internal mold.As Figure 11, two the first internal molds 3 dock mutually by connecting bolt 35, and two the second internal molds 4 dock mutually by connecting bolt 45, and easy accessibility, can repeatedly be used like this, and cost is low.In addition be bolted, the pulling force of two the first internal molds is fixed two external molds, now, the fastening formation of internal mold external mold is whole.
Further, as Fig. 8 and Figure 11, the base plate 32 of the first internal mold is provided with locating piece 323, on the base plate 32 of the first internal mold, be also provided with limited bayonet 321, mutual location while being respectively used to two the first internal mold docking, can realize multiple screens, thereby guarantee described in first that the first internal mold and second described the first internal mold are realized location mutually by draw-in groove and projection.Can form the clamping on the basis being spirally connected of first first internal mold and second the first internal mold.
Further, as Figure 10 and Figure 11, the base plate 42 of the second internal mold 4 is provided with locating piece 423, on the base plate 42 of the second internal mold, be also provided with limited bayonet 421, mutual location while being respectively used to two the second internal mold docking, can realize multiple screens, thereby guarantee described in first that the second internal mold and second described the second internal mold are realized location mutually by mutual clamping.Can form the clamping on the basis being spirally connected of second the first internal mold and second the second internal mold.
In the present invention, in mold framework, pour into a mould one section of monoblock type cable groove of meeting formation outside for one, distance between the distance on the top of two described the first internal mold side plates or the first internal mold opening 30 is the length of one section of monoblock type cable groove, the distance on the top of two described the first internal mold side plates is for example 40 to 80cm, be for example 60cm, to obtain suitable length, the connection through multistage monoblock type cable groove, can form the longer cable trough of downline.
The assembling process of the making mould of monoblock type cable groove is: the first external mold 1 is connected into integral body by bolt hole with bolt with described the second external mold 2, form external mold framework, external mold framework is put into respectively in the bottom of 2 the first internal molds 3, the second internal mold 4 from two openings of external mold, and with screw rod, the first internal mold 3, the second internal mold 4 are used respectively fastening, now, the top of two internal molds is by the second template 12, the 5th template 22 diebacks of external mold, prevent the swollen mould of external mold, by inside and outside die combination, form the filling chamber 5 between cable trough entity cavity and internal mold and external mold.The making set of molds of monoblock type cable groove is dressed up after integral body, place on precast base, after the making mould of monoblock type cable groove is fastening with pull bar, in mould, build concrete, by 5 cast of the filling chamber between internal mold and external mold, after concrete strength reaches 2.5MPa, by demoulding hole 325 and 425 demouldings of demoulding hole, remove each external mold and internal mold, cable trough is produced and is finished.
The making mold integral of monoblock type cable groove only needs fixing several places screw plastic, within every 8 hours, can have enough to meet the need once, improves operating efficiency and the mould number of turnover.According to current similar cover-plate type electric cable slot mold construction experience, need when meeting 18.5Mpa, concrete strength just can carry out form removal, and striking time needs 48 hours the most early.And the making mould of monoblock type cable groove of the present invention is without bed die, after concrete initial set, it is collapsible die that intensity meets 2.5Mpa, only needs 8 hours, greatly improves mould week transfer efficient.
For adopting similar punching block, make the making mould of monoblock type cable groove of the present invention, number of fitting parts increases, 16 lens need to be set just can be completed this template peace and tear that (monolithic internal mold splits into 6 open, external mold splits into 4, two groups of internal molds add that external mold amounts to 16), and installation accuracy is poor, working procedure is loaded down with trivial details, and effect is lower.And mould of the present invention adopts pin-connected panel piecemeal set of molds synthetic whole, easy accessibility.Each internal mold and external mold are mould of plastics in addition, transport light.
Effect of the present invention is fast, efficiency is high, meets energy-saving and emission-reduction requirement.
The foregoing is only the schematic specific embodiment of the present invention, not in order to limit scope of the present invention.For each part of the present invention can mutually combine under the condition of not conflicting, any those skilled in the art, not departing from equivalent variations and the modification of having done under the prerequisite of design of the present invention and principle, all should belong to the scope of protection of the invention.
