Abstract
The invention relates to an extrusion molding flow distributing and forming mold core for a steel wire gauze framework plastic composite tube. The extrusion molding flow distributing and forming mold core comprises a flow distributing core shaft and a forming core shaft. The forming core shaft is coaxially arranged at the front end of the flow distributing core shaft; a plurality of half through grooves extending in the axial direction are uniformly formed in the peripheral surface of the flow distributing core shaft; a plurality of flow distributing grooves extending in the axial direction are uniformly formed in the peripheral surface of the front section of the flow distributing core shaft; the flow distributing grooves and the half grooves are distributed in a spaced mode and do not interfere with each other; the flow distributing grooves allow glue flow to be uniformly distributed to the circumference of a steel wire gauze framework and overflow from the steel wire gauze framework so as to completely cover the periphery of the steel wire gauze framework; and the outer diameter of the forming core shaft is smaller than or equal to the minimum outer diameter of the position, corresponding to the half grooves, of the flow distributing core shaft, and when the steel wire gauze framework passes through the forming core shaft, the glue flow completely covers the inner circumference of the steel wire gauze framework. By means of the extrusion molding flow distributing and forming mold core for the steel wire gauze framework plastic composite tube, a plastic tube body completely covering the steel wire gauze framework can be formed by one-time extrusion molding on the steel wire gauze framework, and the obtained steel wire gauze framework plastic composite tube is free of a layered structure, high in pressure-bearing capacity and long in service life.
Description
Technical field
The present invention relates to a kind of extrusion moulding core rod.
Background technology
Steel wire mesh frame plastic pipe has higher intensity compared with common plastics tube, bears higher pressure, is widely used in
Town water supply, combustion gas, special industrial fluid such as oil, chemistry stream agent, ore pulp, industrial wastewater, pressed powder, low high-temp liquid etc.
The higher tubing of pressure-bearing.
Traditional steel wire mesh frame plastic composite tube mostly refers at least to five layers of composite construction, except the steel positioned at central core
Outside silk screen, the also two-layer hot melt adhesive layer inside and outside next-door neighbour's steel wire, along with inside and outside two layers of plastic layer.Steel wire mesh frame layer and
Inside and outside plastic layer passes through PUR bonding.Although steel wire mesh frame plastic composite tube steel wire and the plastic layer using this structure
In conjunction with more firm, but there is also technological deficiency simultaneously, because PUR is different with the material of plastic layer, both is pressure
Have differences with heat resistance, under harsh operating mode, PUR is easily deformed timeliness, lead to disengage with plastic layer, when serious
Lead to the rupture of pipeline.And the structure of this ectonexine plastic layer has that manufacturing procedure is complicated, ectonexine plastic layer needs twice
, there is energy consumption and the high defect of the cost of raw material in extrusion moulding process.
On the one hand in order to improve the structure of steel wire mesh frame plastic composite tube, decrease or even eliminate layer structure to keep away as far as possible
Exempt from the phenomenon that degumming layering occurs in operating mode, on the other hand in order to shorten production process, save production cost.Present inventor
The manufacture method of extrusion moulding of design, steel wire mesh frame is directly coated in plastic tube body, no layer structure, once squeezes
Molded, operation is simple, greatlys save production and cost of material.Design corresponding formation die core to realize in steel wire mesh frame
Last moulding plastics body is the application technical barrier to be solved.
Content of the invention
The technical problem to be solved is to provide a kind of extrusion molding to shunt formation die core for above-mentioned prior art, main
It is used for realizing once extrusion moulding plastic tube body on steel wire mesh frame, and allow plastic tube body coat steel wire mesh frame completely,
Fluid sizing material can be allowed to be uniformly distributed in steel wire mesh frame circumference, and it can be avoided that what steel wire mesh frame was extruded by sizing material and deformed
Situation occurs, and allows the once injection moulding of plastic tube body smoothly to occur.
The present invention the adopted technical scheme that solves the above problems is：A kind of steel wire mesh frame plastic composite tube extrusion molding divides
Stream formation die core, includes shunting mandrel and forming core shaft, and described forming core shaft is co-axially located at the front end shunting mandrel, described point
Some axially extended insertion half grooves, the supporting steel wire one of steel wire mesh frame innermost layer is uniformly offered on the outer peripheral face of stream mandrel
One correspondence is embedded in described half groove, and in the presence of pull strength, steel wire mesh frame is passed through shunting mandrel along half groove；Described point
Some axially extended splitter boxs, described splitter box and described half groove interval point are uniformly offered on the outer peripheral face of stream mandrel leading portion
Cloth and non-interference, splitter box makes stream shape sizing material by uniform divided flows to steel wire mesh frame circumference, and overflows across steel wire mesh frame to steel
Silk screen skeleton periphery forms and coats completely；Further, the external diameter of described forming core shaft is less than or equal to shunting mandrel corresponding half
Minimum outer diameter at groove, when steel wire mesh frame passes through forming core shaft, stream shape sizing material forms to steel wire mesh frame inner circumferential and wraps completely
Cover.
Preferably, described half groove is arcuate groove.
Further, it is shaped to stripe-shape plane to meet the winding being wrapped in outside supporting steel wire layer between adjacent described half groove
Steel wire floor remains discontiguous state with shunting mandrel.
The support including extending along plastic tube length direction of the shunting corresponding steel wire mesh frame of formation die core of the application
Steel wire floor, and the winding steel wire layer being spirally wound on described supporting steel wire layer is it is preferable that winding steel wire layer includes right-handed screw again
The mid-wrap steel wire floor being wrapped on supporting steel wire layer and backpitch are wrapped in the outer layer on described mid-wrap steel wire floor
Winding steel wire layer.
Compared with prior art, it is an advantage of the current invention that：Provide a kind of extrusion molding shunting formation die core, for realizing
Steel wire mesh frame last time extrusion moulding is the plastic tube body entirely coating steel wire mesh frame, and process is simple reduces production cost,
Gained steel wire mesh frame plastic composite tube no layer structure, steel wire mesh frame is from as welding seam, multiple tube circumference performance
It is subject to
Uniformly, composite pipe pressure-bearing ability is higher, and service life is longer for power.
Brief description
Fig. 1 be the embodiment of the present invention in extrusion molding shunt formation die core structural representation.
Specific embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
