Abstract
The invention relates to a mold for forming equipment of a winding type socket and spigot joint. The mold comprises a mold body and a mold clamping part which are integrally designed, wherein the outer diameter of the mold body is fixed while the outer diameter of the mold clamping part is variable; the mold body comprises a base and a partitioning plate which are opposite to each other; a closing ring is arranged between the base and the partitioning plate and connects the base with the outer edge of the partitioning plate. The mold is applicable to production of winding pipes.
Description
Technical field
The present invention relates to winding pipe production technical field, refer to especially for the mould on winding-type bell and spigot joint former.
Background technology
The material that existing helically-wound shaped plastic tube is used when Wrapping formed is different, can be divided into the specific product forms such as hollow spiral tube, carat pipe, reinforced steel-band winding pipe, internal-rib enhancing winding pipe, plastic-steel spirally-wound pipe.Because it has higher high ring rigidity, be widely used in the occasions such as draining, low pressure water supply.The connected mode of pipeline mainly contains the various ways such as the connection of electric smelting band, thermal shrinkable sleeve connection, the connection of electric smelting socket joint, the connection of socket joint sealing ring, clamp connection.This wherein, electric smelting band connects and to be connected with thermoplastic cover because of cost compared with low to application widely, but higher to construction environment and technology, and the situation of construction quality Yin Ge construction team is different and can not get guarantee, the connection of relatively more applicable small-bore pipeline.Clamp connection mode cost compare is high and connected mode reliability is poor.Socket joint connects and comprises electric smelting socket joint and sealing ring socket joint, the former of bell and spigot joint mainly contains two kinds of injection molding and winding-types, injection molding former is exactly by injection machine and mould, by joint in the injection mo(u)lding of tubing two, equipment increases along with the increase of caliber, therefore, injection mo(u)lding joint is only applied to small-bore pipeline at present, and price is higher.Filament winding process is similar to the mode of tube forming, and plastic strip is wrapped in to tubing two, by mould molding, is bell and spigot.
At present, conventional mould is divided into two classes, one class is taper fixed mould, utilize fixedly tubing of diameter that taper increases gradually, but because the caliber of the tubing of specification of the same race exists error, make tubing fixing change in location on mould larger, the bell and spigot of last moulding also just exists and larger error; Another kind of is the mould of outer radius variable, and it has telescopic shell for fixing tubing, but because the caliber of the tubing of specification of the same race exists error, causes the external diameter of mould to change greatly, makes the bell and spigot of last moulding also have larger error.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of variable external diameter for the mould on winding-type bell and spigot joint former, this mould stability is higher, and result of use is better, error is less, and thermal conductivity factor is lower, can solves and when plastic strip is wound on mould, sharply shrink and affect the problem of the smooth degree of goods inwall.
For solving the problems of the technologies described above, the technical solution used in the present invention is: for the mould on winding-type bell and spigot joint former, the die ontology and the mould holding portion that comprise integral type design, described die ontology external diameter is fixed, mould holding portion outer radius variable, die ontology comprises base and the dividing plate being oppositely arranged, and between base and dividing plate, is provided with closed-loop, and closed-loop is connected the outer of base and dividing plate.
As a kind of preferred version, described closed-loop outer wall adopts nonmetallic materials to make.

As a kind of preferred version, described gripper shoe rear and front end is respectively arranged with boss, and boss is inconsistent with the rear end face of top board and the front end face of base respectively.
As a kind of preferred version, described clamping part housing is circular arc type, and the part that clamping part housing front end surpasses boss front end face is intilted inclined-plane.
As a kind of preferred version, described track plates is provided with four.
As a kind of preferred version, described front push rod is provided with four.
The invention has the beneficial effects as follows: above-mentioned mould is owing to being provided with the mould holding portion of die ontology and the variable external diameter of fixed outer diameter, the pipe fitting that can adapt to different bores, and because the external diameter of die ontology is constant, make the bell and spigot bore of final molding constant, error is less, stability is higher, because adopting nonmetallic materials, closed-loop makes again, thermal conductivity factor is lower, can prevent from sharply shrinking when plastic strip is wound on mould and affect the smooth degree of goods inwall, having save the link to die surface heating.
