Colour circle for the colo(u)r streak charity of PE Gas Pipe surface

Technical field

The present invention relates to a kind of formation of tubes equipment, be particularly used for the colour circle of PE Gas Pipe surface colo(u)r streak charity.

Background technology

The municipal tubing market of PE Gas Pipe China at present, plastic conduit just in stable development, PE Gas Pipe, PP-R pipe, UPVC pipe all occupies a tiny space, and the growth momentum that wherein PE Gas Pipe is powerful attracts people's attention the most.The use neck of PE Gas Pipe Territory is extensive.Wherein feed pipe and Gas Pipe are the application markets of two maximum.PE resin, is to be polymerized by monomer ethylene, Due to different because of the polymeric reaction condition such as pressure, temperature when polymerization, the resin of different densities can be drawn, because of and have high density Dividing of polyethylene, medium density polyethylene and Low Density Polyethylene.

And the multiple colo(u)r streak general objects axially arranged at its outer wall along PE Gas Pipe are not configured to attractive in appearance, it is to pacify The full requirement produced so that health environment harm is had one the most eye-catching to get information about most by the medium in pipeline, in order to can be just Really carry out security protection and emergency processing and emergency management and rescue, endanger attribute, " GB7231-according to the health environment of pipeline medium 2003 " described in pipeline identification color colour atla, free of contamination to human body fanout free region, such as water etc., mark smaragdine at pipeline outer wall Colo(u)r streak；High temperature, human body there is burn hazard, such as steam etc., at the colo(u)r streak of pipeline outer wall mark large red；Gas (specifies certain Kind of material gases, such as nitrogen, argon etc., but the most oxygenous), the colo(u)r streak of yellow in pipeline outer wall marks.

But during the production of PE Gas Pipe, the colo(u)r streak on its surface itself is integrally forming typically by combination process and body, I.e. being fixed with multiple nozzle in the feeding part of Gas Pipe injection moulding machine, in nozzle, the colorant of different colours initially forms color Line, to be attached on Gas Pipe outer wall.But in prior art, due to the needs of technique, nozzle connects with the feed end of forming machine For entirety, once the color number of lines on pipeline increases or reduces, then need to change the feed end of forming machine in the lump with nozzle, To meet actual production demand, but remove the use cost of the feed end of newly-increased different spray nozzles number, to different model Feed end is replaced or safeguards, expends substantial amounts of manpower and materials, i.e. causes the reduction of Gas Pipe production efficiency.

Summary of the invention

Present invention aim at providing the colour circle for the colo(u)r streak charity of PE Gas Pipe surface, it is ensured that fire at the PE of different tube diameters Trachea is the quick-replaceable of colour circle when colo(u)r streak charity.

The present invention is achieved through the following technical solutions:

For the colour circle of PE Gas Pipe surface colo(u)r streak charity, including shaping mould and the plug that matches with shaping mould, also include The ring body being arranged in shaping mould, forms an annular runner, at described ring body between described inner wall of ring body and plug outer wall Have cannelure on outer circle wall, ring body inner peripheral wall has the colorant that multiple and described cannelure connects and portals, described The colorant inlet hole connected with cannelure is had on shaping mould.In prior art, the nozzle of colo(u)r streak charity and the feed end of forming machine It is connected so that when Gas Pipe changes colo(u)r streak quantity, i.e. need to change both together, complex operation, add simultaneously The use cost of colo(u)r streak charity equipment；For such problem, inventor designs the colo(u)r streak cloth of shaping mould and ring body clearance fit Executing structure, plug, as the support member of Gas Pipe, is placed in shaping mould, and colour circle is provided with multiple colorant and portals, to difference The Gas Pipe of colo(u)r streak quantity is shaped adding man-hour, i.e. only need to be by changing ring body, to ensure quantity that colorant portals and to treat into Molded line cable colo(u)r streak quantity is identical, and then avoids the feeding part integral replacing of forming machine, optimizes the processing technique of cable, Greatly reduce the cost of Gas Pipe colo(u)r streak charity simultaneously.

Specifically, during work, the Gas Pipe material under molten condition initially enters to the runner of annular, Gas Pipe material Continue to move to along runner, now the colorant being similarly under molten condition is entered in cannelure by colorant inlet hole, by annular The guiding of groove so that multiple colorants are all filled full colorant in portalling, colorant and Gas Pipe material are direct in runner after converging Composite molding, outer wall belt have the Gas Pipe of colo(u)r streak；And in combination process, due under molten condition colorant by warp successively Crossing after colorant inlet hole, cannelure and colorant portal and be injected in runner, now the heat of colorant itself is more by loss, and enters The Gas Pipe material entered in runner is compared, and the time of colorant molding is shorter, i.e. it can be avoided that colorant and Gas Pipe material are at runner Inside lump together, prevent the colo(u)r streak of charity from losing its mark action.

Along the axial rib being interval with multiple rectangle in its circumferential wall of described ring body, in multiple described ribs two Being one group, often a group rib corresponding described colorant respectively portals, colorant portal with two ribs in often group before gap even Logical, and the internal diameter that often spacing between two ribs is portalled more than or equal to described colorant in group.In colorant and Gas Pipe After material mixes in entering into runner, the line style of colo(u)r streak is easily subject to the extruding of Gas Pipe material and distortion occurs, and then impact The effect of colo(u)r streak mark, therefore, inventor is spaced the rib arranging multiple rectangle on inner wall of ring body, and two ribs constitute one The extension then portalled as colorant in space between group, and two ribs, i.e. colorant can be along two after spilling of being portalled by colorant The channel-shaped space that rib is constituted continues to move to, rather than is mixed together with Gas Pipe material, meanwhile, and Gas Pipe in runner Material occupies most of area of runner as main body, and colorant then gradually cools down under the guiding of two ribs, i.e. straighe Standard linear.Wherein, the internal diameter that often spacing between two ribs of group is portalled more than or equal to described colorant, i.e. when compound During the Gas Pipe of molding large-size, correspondingly the line style width of colo(u)r streak is relatively big, and the now colorant extension in runner of portalling is empty Between need to increase, then operator directly use spacing between two rib bodies just can incite somebody to action this more than the portal structure of internal diameter of colorant Class problem directly solves；When the Gas Pipe of composite molding reduced size, correspondingly the line style width of colo(u)r streak is less, now colorant The wider space portalled in runner is maintained the statusquo, then operator directly use the spacing between two rib bodies equal to color Such problem just can directly be solved by the portal structure of internal diameter of material.

Multiple described colorants portal and are uniformly distributed along ring body circumference.As preferably, the distribution situation that colorant portals directly is determined Determine the distribution situation of colo(u)r streak on Gas Pipe outer wall, therefore, for can preferably embody colo(u)r streak mark action in Gas Pipe, color The circumference that material portals along ring body is uniformly distributed, i.e. colo(u)r streak is just uniformly distributed, to facilitate eye-observation.

Described ring body, plug and described shaping mould three are coaxial.As preferably, by ring body, plug and described molding Mould three be coaxially disposed so that the Gas Pipe of molding and colo(u)r streak uniform force in runner, it is to avoid because of ring body, plug and one-tenth Any parts unbalance stress between pattern three and shake, it is to avoid Gas Pipe generation bird caging in forming process and cause The Gas Pipe scrappage of finished product improves.

Described rib upper surface away from described plug outer wall spacing is described gate thickness 1/5 ~ 2/5.In prior art, The most easily there is fracture phenomena in the colo(u)r streak part of Gas Pipe, and then causes Gas Pipe to leak air and cause safety Accidents etc., trace it to its cause and are because colorant in the contact area with Gas Pipe material compound tense, colorant and Gas Pipe property management wall relatively Few, viscous viscosity is the highest caused, and it is thick in the present invention, the rib upper surface spacing away from described plug outer wall to be arranged on described runner In the range of the 1/5 ~ 2/5 of degree, ensureing that colo(u)r streak possesses in certain thickness premise, the colorant in runner is in two rib institutes of removal Constituting and be divided into two parts after the groove-like structure removal of a guide function, first the colo(u)r streak being i.e. close to inner wall of ring body side dispels the heat Molding, and the colo(u)r streak away from inner wall of ring body side is slower and unformed because dispelling the heat, this unformed part continues and Gas Pipe material Contact, by both mutual extruding, finally increases connecing between the colo(u)r streak away from inner wall of ring body side and Gas Pipe material Contacting surface is amassed, and reduces Gas Pipe and the probability of fracture phenomena in use occurs.

The present invention compared with prior art, has such advantages as and beneficial effect:

1, the colour circle in the present invention is provided with multiple colorant and portals, and the Gas Pipe of different colo(u)r streak quantity is being shaped processing Time, i.e. only need to be identical with cable colo(u)r streak quantity to be formed to ensure the quantity that colorant portals by changing ring body, and then avoid By the feeding part integral replacing of forming machine, optimize the processing technique of cable, greatly reduce Gas Pipe colo(u)r streak charity simultaneously Cost；
