Abstract
The invention relates to an irregular shaped opening die of a pipe material with a polyethylene multilayer wound structured wall. The opening die comprises an opening die body. A coaxial supporting pipe outlet and a coaxial supporting pipe coating arc material belt outlet are arranged on an outlet end of the opening die body. The supporting pipe coating arc material belt outlet is arranged around the peripheral of the supporting pipe outlet. The innovation points of the invention are that: the supporting pipe coating arc material belt outlet is in a 6 shape, a reversed 6 shape, a 9 shape, or a reversed 9 shape composed of an annular part and a tail part; a non-continuous interval is arranged between the annular part of the arc material belt outlet and the tail part. According to the irregular shaped opening die, a 6-shaped arc material belt outlet is arranged, and the annular part of the arc material belt outlet and the tail part of the arc material belt outlet are not sealed, such that heat is easy to be dissipated. Therefore, the supporting pipe is not completely coated, such that the supporting pipe can not be softened by heating, and prominences are not easy to appear on the coating material belt. When the supporting pipe is wound on the surface of a die with equidistance, the supporting pipe is completely coated by material belt on the tail part. Therefore, product shape height is ensured, ring stiffness of the product is improved, and appearance quality is improved.
Description
Technical field
The invention belongs to plastic pipe processing unit (plant) field, particularly a kind of Special-shaped opening mold for polyethylene multilayer winding structure wall pipe materials.
Background technology
Polyethylene spirally enwound structure-wall tubular product is that hot technique winding pipe is taking high-density polyethylene resin as main raw material(s), adopt hot winding shaping process, taking polypropylene single-wall corrugated pipe as auxiliary support structure, a kind of special construction wall tube material with higher critical external compressive resistance ability of making.Its mode of production: raw material is extruded into respectively to flat material strip and the arc material strip in order to coated skeleton pipe through runner, mouthful mould after vacuum feeder is delivered to heating in extruder, plasticizing, homogenizing, is equidistantly wrapped on die surface.At present, the arc material strip die geometry form of coated skeleton pipe has two kinds: the one, and U-shaped structure, half coated skeleton pipe, but in the time that skeleton pipe is equidistantly wrapped on die surface, easily cause material strip bag not live skeleton pipe and expose, form product defects, product ring stiffness is low simultaneously.The 2nd, O type structure, skeleton pipe is encased completely, but easily cause between skeleton pipe and coated material strip, heat is loose does not go out, in the time that being equidistantly wrapped on die surface, easily causes skeleton pipe the deliquescing of being heated of skeleton pipe, the circular ellipse that becomes, type is high to be reduced, simultaneously, coated material strip easily forms bulge, reduces product ring stiffness and presentation quality and is difficult to ensure.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide one to improve product ring stiffness by intact coated skeleton pipe, meanwhile, improve the Special-shaped opening mold for polyethylene multilayer winding structure wall pipe materials of product appearance quality.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of Special-shaped opening mold for polyethylene multilayer winding structure wall pipe materials, formed by mouth mould main body, be shaped with coaxial skeleton pipe outlet and be coated the outlet of skeleton pipe arc material strip at the port of export of this mouthful of mould main body, coated skeleton pipe arc material strip discharge ring is around the periphery of skeleton pipe outlet, it is characterized in that: the figure-six of described coated skeleton pipe arc material strip outlet for being formed by ring part and afterbody, anti-figure-six, 9 fonts or anti-9 fonts, be shaped with discontinuous interval parts between the ring part of arc material strip outlet and afterbody.
Advantage of the present invention and beneficial effect are:
This special mouth is molded with the coated skeleton pipe arc material strip outlet of 6 types, open-ended between its ring part and afterbody, and heat easily distributes, and like this, skeleton pipe is not completely encased, can be because of the deliquescing of being heated, meanwhile, coated material strip is difficult for forming bulge.In the time that skeleton pipe is equidistantly wrapped on die surface, the material strip of afterbody is completely coated by skeleton pipe again, has ensured that product type is high, has improved ring stiffness, has improved presentation quality.This special mouth mould can be widely used in the technical field of plastic pipe processing.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of prior art O type mouth mould;
Fig. 3 is the structural representation of U-shaped mouthful of mould of prior art.
Detailed description of the invention
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of Special-shaped opening mold for polyethylene multilayer winding structure wall pipe materials, formed by mouth mould main body 1, be shaped with coaxial skeleton pipe outlet 4 and coated skeleton pipe arc material strip outlet 2 at the port of export of this mouthful of mould main body, coated skeleton pipe arc material strip discharge ring is around the periphery of skeleton pipe outlet, its innovation is: the figure-six of described coated skeleton pipe arc material strip outlet for being made up of ring part and afterbody, anti-figure-six, 9 fonts or anti-9 fonts, be shaped with discontinuous interval parts 3 between the ring part of arc material strip outlet and afterbody.
After this special mouth mould is arranged on extruder, skeleton pipe goes out pipe from skeleton pipe exit position, the arc material strip of coated skeleton pipe, from coated skeleton pipe arc material strip exit position discharging, forms the coated skeleton pipe of polyethylene, is equidistantly wrapped in and in tube surfaces, forms polyethylene spirally enwound structure-wall tubular product.
In the present embodiment, taking 6 subtypes as example, special mouth mould, according to installation site difference, also can form anti-6 subtypes, 9 subtypes and anti-9 subtypes.Between skeleton pipe and coated material strip, heat sheds effectively, has improved equally ring stiffness, has improved presentation quality.Under identical working condition, the polyethylene multilayer winding structure wall pipe that adopts special mouth mould of the present invention to produce has the outstanding advantages that product ring stiffness is high, can reach design ring stiffness completely.
Although disclose for the purpose of illustration embodiments of the invention and accompanying drawing, but it will be appreciated by those skilled in the art that: not departing from the spirit and scope of the present invention and claims, various replacements, variation and amendment are all possible, therefore, scope of the present invention is not limited to embodiment and the disclosed content of accompanying drawing.
