Description
Technical field
The present invention relates to a kind of cooling system, specifically, relate to a kind of core of pipe extrusion mold cooling system.
Background technology
Plastic pipe is widely used in the numerous areas such as industry and municipal supply and drain water system, combustion gas conveying, power communication with its excellent combination property.In the processing and manufacturing process of plastic pipe, especially, in the extrusion molding process of tubing, cooling and shaping device has determined the length of tube extrusion production line, and cooling procedure is the key factor that affects extruding production line production efficiency and product quality.Especially cooling whether the putting in place of mold core directly has influence on extrusion efficiency and the quality of the tubing of extruding.Prior art is manufactured the cooling mode that all adopts circulation pipe box of mold core of tubing, and its deficiency is: the cooling oily circulating cooling method of traditional mould top layer bush structure that only adopts of mold core of prior art.Oil cooling can not effectively carry out effectively cooling to extruding pipe material inwall, only mould internal layer is carried out to heat exchange, can not effectively improve extrusion efficiency.And exist production cost higher, inefficiency, the shortcoming such as energy consumption is high, and goods are rough.
Summary of the invention
The technical problem to be solved in the present invention is, the deficiency existing for prior art, provides a kind of and can carry out to extruding pipe material inwall the core of pipe extrusion mold cooling system of effective cooling.
The present invention is that the technical scheme that its technical problem of solution adopts is:
Core of pipe extrusion mold cooling system provided by the invention, comprises the core that is arranged on described extrusion die inside, is provided with and independently extrudes mutually passage and center cavity on described core, in described center cavity, is equipped with cool air hose;
Wherein said cool air hose comprises air intake cylinder, middle air duct and chimney fan, and it is outside that described air intake cylinder stretches out described core;
On described middle air duct outer wall, be provided with thermal insulation layer;
In the inner position near extruding passage of described core, be also provided with cooling duct, one end, described cooling duct connects outer air-intake device, and the other end connects hot-blast outlet;
Described chimney fan is connected with described outer air-intake device.
In another preference, described air intake cylinder connecting fan.
In another preference, described chimney fan end has pre-large post-small tapered opening.
In another preference, described tapered opening place is provided with volume adjusting apparatus, and described volume adjusting apparatus comprises screw rod and the conical plug corresponding with described conical outlet, and described conical plug is fixed on screw rod.
In another preference, described hot-blast outlet connects hot air recovery.
In another preference, described air intake cylinder is connected on described middle air duct by connecting ring.
Implement core of pipe extrusion mold cooling system of the present invention, there is following beneficial effect:
1, independently air cooling system is a kind of novel cooling system, installs more convenient in the process of using.The volume adjusting apparatus that different size is installed by replacing can effectively make tubing cool down rapidly when extruding super abundant wall tube material, reduces the configuration of vacuum tank and spraying box equipment, improves pipe extruded velocity and quality;
2, when improving mold core cooling system, also improved the structure of existing mold, original solid mould middle part is processed as to through hole state, itself increased the contact area of die cavity and outside air, place is also improved the radiating condition of mould self, when stretching thin-wall pipes, can greatly improve draw speed, while stretching super abundant wall tube material, can improve stretching efficiency;
3, utilize air as cooling medium, i.e. environmental protection low energy consumption again, and cost is low;
4, the hot blast of cooling rear generation can carry out energy recycling, as being dried for raw-material.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the structural representation of core of pipe extrusion mold cooling system of the present invention;
In figure: 1, cool air hose, 2, core, 11, air intake cylinder, 12, middle air duct, 13 chimney fans,, 14, thermal insulation layer, 15, tapered opening, 16, connecting ring, 21, extrude passage, 22, outer air-intake device, 23, cooling duct, 24, hot-blast outlet.
The specific embodiment
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in more detail:
Fig. 1 has illustrated the structure of core of pipe extrusion mold cooling system provided by the invention, as shown in the figure, this core of pipe extrusion mold cooling system comprises the core 2 that is arranged on described extrusion die inside, on described core, be provided with and independently extrude mutually passage 21 and center cavity, in described center cavity, be equipped with cool air hose 1; Wherein said cool air hose 1 comprises air intake cylinder 11, middle air duct 12 and chimney fan 13, and it is outside that described air intake cylinder 11 stretches out described core; On described middle air duct 12 outer walls, be provided with thermal insulation layer 14; In the inner position near extruding passage 21 of described core 2, be also provided with cooling duct 23, one end, described cooling duct connects outer air-intake device 22, and the other end connects hot-blast outlet 24; Described chimney fan 13 is connected with described outer air-intake device 22.During work, extrude in passage 21 and be filled with extruded material, due to cooling duct 23, next-door neighbour extrudes passage 21, so that air cooling system can directly carry out the inwall of extruding pipe material is cooling, cooling effect is directly rapid.
