Abstract
The utility model relates to a PVC pipe manufacturing die mainly used for manufacturing steel bar reinforced pipe, wherein, two semicircular modules inosculate with each other; internal molds of two semicircular modules are provided with ring-shaped grooves and vertical grooves which are staggered and communicated with the grooves; the space between the ring-shaped grooves and the vertical grooves are provided with fine vertical grooves or fine transverse grooves. The utility model has the advantages that: as the ring-shaped stiffener grooves and the vertical stiffener grooves arranged on the wall of a mould for steel bar reinforced pipe are staggered and communicated with each other, the manufactured steel bar reinforced pipes can bear pressure as well as extrusion, is high in strength, can ensure the partial strength of the pipes changeless, and can ensure pipes infrangible when the foundation sinks.
Description
Technical field: the utility model relates to a kind of pvc pipe and makes mould, is mainly used in the making riffled tube.
Background technology: at present, have only ring-type shape groove in the pvc pipe shaping mould.It is not enough point: made riffled tube, its intensity does not reach requirement, when riffled tube is pushed by hard material (as metallic plate, stone, glass etc.), very easily cause the decline of tubing local strength, thereby can't reach the technical indicator of regulation, the result causes the bearing capacity of tubing to reduce significantly, and particularly when being subjected to geostatic pressure, its riffled tube is easily broken.
Summary of the invention: technical problem to be solved in the utility model is, adopt riffled tube that the riffled tube shaping mould makes when the construction and the backfill soil cubic meter of stone, when running into hard material, setting of ground, can guarantee effectively that the intensity of riffled tube is constant, pressure-bearing, hold the constant and tubing of crowded intensity and do not break.In order to solve the problems of the technologies described above, the utility model is by carrying out science design and rational deployment to the structure of riffled tube shaping mould internal mold, make the riffled tube that adopts its riffled tube shaping mould made can overcome extruding force effectively, thereby avoid effectively that riffled tube is squeezed, pressurized, be subjected to setting of ground and the problem of breaking from the outside.Its technical scheme: a kind of riffled tube shaping mould, the module of two semicircle shapes matches, the longitudinal fluting (2) that the internal mold of two semicircle shape modules has annular recess (1) and interlocks and be communicated with groove.Space between annular recess and longitudinal fluting has tiny longitudinal fluting or tiny transverse concave groove (3).Adopt the riffled tube shaping mould of technique scheme manufacturing, cyclic reinforcing rib groove and waling groove submission misphase is intercommunicated owing to having on the wall of riffled tube shaping mould.Therefore, made riffled tube when local pressurized, squeezed, when being rolled over, its suffered pressure, squeeze and folding be not by pressurized, the part of being squeezed, being rolled over bears, but come pressure-bearing, hold and squeeze and hold folding by cyclic reinforcing rib and the waling submission misphase reinforcement body that constitutes that connects.Its result: not only the riffled tube pressure-bearing, hold crowded, intensity is high, when being pushed by hard material, can guarantee that tubing local strength is constant, and meeting the setting of ground amplitude when little, can guarantee that tubing does not break.
Description of drawings:
Fig. 1 is that structural representation cuts open in the master office of looking of riffled tube shaping mould.
Fig. 2 is that A among Fig. 1 is to structural representation.
Fig. 3 is the B-B sectional structure schematic diagram among Fig. 1.
Fig. 4 is the C-C sectional structure schematic diagram among Fig. 1.
Fig. 5 is that the D-D among Fig. 1 amplifies the sectional structure schematic diagram.
Concrete embodiment: with reference to accompanying drawing 1～5, adopt the existing mold process technology to make mould, the module of two semicircle shapes matches, the longitudinal fluting (2) that the internal mold of two semicircle shape modules has annular recess (1) and interlocks and be communicated with groove.Space between annular recess and longitudinal fluting has tiny longitudinal fluting or tiny transverse concave groove (3).Have tiny longitudinal fluting or tiny transverse concave groove purpose is: the one, improve the bearing strength of made riffled tube tube wall, the 2nd, improve the adhesion of made riffled tube tubing and earth.
Claims (2)
1, a kind of riffled tube shaping mould, it is characterized in that: the module of two semicircle shapes matches, the longitudinal fluting (2) that the internal mold of two semicircle shape modules has annular recess (1) and interlocks and be communicated with groove.
2, riffled tube shaping mould according to claim 1 is characterized in that: the space between annular recess and longitudinal fluting has tiny longitudinal fluting or tiny transverse concave groove (3).
