Abstract
The utility model relates to a plastics tubular product technical field, concretely relates to take vacuum -exhaust's effective cladding mould of hot winding. Including interior die body, outer die body, with the mandrel of centre form body coupling and the bush that matches with the mandrel, the rear portion of interior die body is equipped with the stifled plug member in vacuum, is equipped with the vacuum aspirating hole that matches on the outer wall of outer die body and interior die body respectively. Air through controlling between vacuous big young pathbreaker's coating and the interior stay tube is taken away, makes coating and stay tube tightly paste together, can also improve the appearance quality of tubular product in order to improve the tubular product bulk strength like this.
Description
Technical field
The utility model relates to plastic pipe technical field, is specifically related to a kind of hot winding pipe coating mould with vacuum exhaust.
Background technology
Winding structure wall pipe belongs to chemical building material field; mould Dai Gang, to mould the regeneration product for cement; be widely used in municipal drainage; remote low-pressure water delivery; mine and chemical industry draining, the making etc. of irrigation and water conservancy irrigation and ventilation shaft and pressure vessels for the chemical industry, to the saving energy; decreasing pollution, protection of the environment is significant.Winding structure wall pipe is in the market full-plastic winding structure wall pipe mainly, full-plastic winding structure wall pipe has good low temperature resistant fragility and high welding performance, and its toughness is better, and boundary of works area is extensive, the ability of being suitable for is strong, and service life also can reach 50 years.
When hot winding structure pipe is produced, the external diameter of inner support tube is all less than the internal diameter of coating mould core, air will be there is between inner support tube and clad like this when producing, in the extraordinary situation of clad material tensile property, stretched clad diameter reduces, air can be squeezed away, but when clad material tensile property bad or wall thickness is too thin or other impact under, there is partial air will be coated between inner support tube and clad, be about to the outer surface bonding with internal layer at cage walls and form bubble not of uniform size, when such cage walls and pipe material inner wall bond, rough edge will be formed at pasting together of boundaries, so namely, have impact on the overall performance of tubing, cause waste of material, also have impact on tubing presentation quality.
Summary of the invention
The purpose of this utility model is to solve the problem, and provides a kind of hot winding pipe coating mould with vacuum exhaust.Of the present utility model in order to address this problem, coating mould is designed to the structure of vacuum-pumping, like this when producing, take away by the air controlled between large young pathbreaker's clad of vacuum and inner support tube, clad and stay pipe are tightly sticked together, so namely, tubing bulk strength can be improved, also improve the presentation quality of tubing.
In order to reach above-mentioned utility model object, the utility model by the following technical solutions:
A kind of hot winding pipe coating mould with vacuum exhaust, the mouth mould comprising interior die body, outer die body, the core be connected with interior die body and match with core, the rear portion of described interior die body is provided with vacuum type of tamper evidence, the outer wall of outer die body and interior die body is respectively equipped with the vacuum pumping hole matched.
As preferably, described vacuum type of tamper evidence is provided with the working hole matched with coated stay pipe.
As preferably, described vacuum pumping hole place is circumscribed with vacuum suction device.
As preferably, described vacuum suction device is vavuum pump.
As preferably, described mouth mould opening part is also provided with compression roller outward.
As preferably, be provided with the vacuum dividing plate by being separated into two spaces in interior die body in described outer die body, vacuum dividing plate both sides are equipped with vacuum pumping hole.
As preferably, described vacuum pumping hole is positioned at the bottom of outer die body or die body.
The utility model compared with prior art, beneficial effect is: taken away by the air controlled between large young pathbreaker's clad of vacuum and inner support tube, clad and stay pipe are tightly sticked together, so namely can improve tubing bulk strength, also improve the presentation quality of tubing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is another kind of structural representation of the present utility model.
In figure: die body in 1,2 outer die bodys, 3 cores, 4 mouthfuls of moulds, 5 vacuum type of tamper evidence, 6 vacuum pumping holes, 7 vacuum suction devices, 8 compression rollers, 9 vacuum dividing plates, 10 charging apertures, 11 inner support tube, 12 working holes, 13 clads.
Detailed description of the invention
