But the mould of the production flexible interface tongue and groove pipe of original vertical core vibrations process using can not be directly used in produces flexible interface steel socket pipe (hereinafter to be referred as the steel socket pipe), reaches the socket groove that GB requires with formation.
The utility model content
The purpose of this utility model is, thereby the production mould that a kind of flexible interface steel socket pipe is provided is applied to the technology of vertical core mould vibrating explained hereafter reinforced concrete sewer pipe in the production of flexible interface steel socket pipe, improve the production efficiency of flexible interface steel socket pipe, realize the reinforced concrete sewer pipe of two kinds of interface shapes of mold production.
For achieving the above object, the production mould of a kind of flexible interface steel socket pipe of the present utility model comprises: core, external mold, upper die and lower die; Fix by alignment pin between described external mold and the core; It is circular that described upper die and lower die all are, and its internal diameter is corresponding with the core diameter, and its external diameter is corresponding with outer mode diameter, is nested in upper end and bottom between external mold and the core respectively, it is characterized in that,
The cross section of described patrix is L shaped, and one edge external mold inwall arranges that the inwall middle part on this limit is provided with the annular steel bar, and this steel bar spiral shell is solid on external mold and patrix inwall; Its another side forms the upper surface of mould;
The cross section of described counterdie is the shape of falling N, and one parallel edges level is positioned at the below, and the outside one end forms flange; Its another parallel edges level is positioned at the top, and the outside one end is placed rubber strip when forming recessed edge effect and being tube forming; Its vertical edges is arranged near the external mold inwall.
As of the present utility model a kind of preferred, described steel bar adopts hexagon socket head cap screw to be fixed on the inwall of external mold and patrix.
As another improvement of the present utility model, the production mould of described flexible interface steel socket pipe also includes the annular steel ring, and this steel ring is arranged on by the gap location between formed counterdie of flange and the external mold.The bar-mat reinforcement welding of steel ring and tubing, the anchoring when being used for moulding reaches the steel socket pipe that GB requires.
As another improvement of the present utility model, the production mould of described flexible interface steel socket pipe also includes rubber strip, and this rubber strip is arranged on by the gap location between formed counterdie of recessed edge and the external mold.When being tube forming, the effect of recessed edge places rubber strip.
Advantage of the present utility model is, the production mould of flexible interface steel socket pipe provided by the utility model, realized adopting vertical core mould vibrating explained hereafter armored concrete steel bellmouth drainpipe, utilize the interior outer mold of the production equipment of original vertical core mould vibrating technology tongue and groove pipe, only need the shape of the upper and lower mould of production equipment of change tongue and groove pipe, under the immovable situation of production technology, produce armored concrete flexible interface steel socket pipe.The concrete uniformity of reinforced concrete sewer pipe that the flexible interface steel socket pipe of producing possesses vertical core mould vibrating explained hereafter is good, the bar-mat reinforcement accurate positioning, and the interface size is accurate, the instant demoulding, steady quality, is easy to control and characteristics that production efficiency is high.
Replacing by upper and lower mould can be switched mutually between the drainpipe of producing steel bellmouth and two kinds of interface shapes of tongue and groove, accomplished to produce the tubing of distinct interface form once cover core and external mold, one mould is dual-purpose, not only improve the product quality and the production efficiency of flexible interface steel bellmouth, and, reduced production cost.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
Shown in Fig. 3～5, mould of the present utility model adopts monomer structure, be divided into core 1, external mold 2, patrix 4 and counterdie 5, connected mode is that core 1 maintains static, and puts into counterdie 5 and external mold 2 successively, and the fixing fixed-site that guarantees of alignment pin is arranged between external mold 2 and the core 1, the beginning cast concrete, after concrete is filled with, patrix 4 is positioned over (between core 1 and the external mold 2) on the concrete, the moulding mouth of pipe.The integral body of upper and lower mould is circular, and its cross section is shown in Fig. 3 and 4, and internal diameter and core diameter coincide, and external diameter and outer mode diameter coincide.
In this example, counterdie 5 has a position of placing steel socket pipe bellmouth steel ring 3, and promptly steel ring 3 is placed on the flange place of counterdie N shape one horizontal sides, and effect is, the steel ring of anchoring tubing steel bellmouth reaches the armored concrete steel socket pipe that GB requires during the mesh reinforcement welding forming of steel bellmouth steel ring and tubing.The steel bar 6 that one moulding spigot seal circle groove is arranged on patrix 4 inwalls, steel bar 6 usefulness screws are fixed on external mold 2 and the patrix 4, finish in moulding, unclamp the screw of fastening steel bar 6 when winning patrix 4 earlier, just can guarantee to win smoothly patrix 4, and form the socket groove that reaches the GB requirement.
In addition, because steel ring and concrete linking are bad, steel ring and concrete seam seep water easily, the rubber strip of placing in the recessed edge in the outside of the last horizontal sides of counterdie 57, with waterproof sealing material groove is added reality after the tube forming maintenance finishes, play waterproof effect.
