Description
Technical field
The present invention relates to molding technology thereof field more particularly to a kind of blow molding methods of TEEE bellows.
Background technique
Blow moulding process is the molding common method of plastic packaging containers, and blow molding is will to squeeze out or injection molding institute
Semi-molten state pipe (or parison) be placed in mold, then Guan Bi mould, be passed through in pipe compressed air extended,
Expansion, is allowed to be tightly attached in die cavity wall, then obtain a kind of processing method of certain form hollow product through cooling and demolding.
The method that tubing formed product generallys use extrusion and blow molding obtains, and medicine bottle, beverage bottle, oil can, lampshade etc.
The mode that some daily necessities rely primarily on injection blow moulding obtains, and for extrusion and blow molding, injection blow moulding has molding
The advantage that period is short, size Control precision is high, wall thickness is relatively uniform, material head is few, but in the prior art, using injection blow moulding work
Skill realizes that the production of TEEE bellows still cannot achieve, because needing blank temperature heating to connect when TEEE forms bellows
Nearly 200 DEG C, pipe occurs collapsing and fold at this time, and in addition during TEEE infrared heating, product will appear contraction, lead to wall
Thick control point is incorrect, during heating caused by pipe fold and shrink ripple when will lead to subsequent blow molding and blow brokenly, wave
Line blow-up ratio is big, if molding ripple at pipe wall unevenness it is even will product ripple blow molding when rupture, cause ripple not at
Type, product do not form.
Summary of the invention
The present invention is in view of the shortcomings of the prior art, provide a kind of product qualified rate height, production cost is low, shortens formed product

Face is heated evenly, and control heating time is 10min, and control heating temperature is 190~200 DEG C；Until pipe softens, cylindrical tube
Just there is non-cylindrical after the heating in base, has an apparent dent when contacting pipe with hard object, and bellows segment do not occur it is non-circular
The phenomenon that cylindricality, in entire softening process, the mandrel component being blow molded in tooling can support pipe, prevent pipe from softening out
Existing collapse and fold；
Step 3: molding: blow molding tooling is sent by transport mechanism to molding station, pipe molding of the mold in blow molding tooling,
It is equipped with closing cylinder at air inlet on ejection seat, the sealing cylinder movement of tooling is blow molded, sealing is withstood, mould is controlled
The angle R that corrugated top portion wedge angle is molded in shaped insert in tool is R0.45mm~R0.55mm；
Step 4: blow molding: the matched ejection assembly of blow molding tooling and lower section cooperates, and knock-pin 43 is dynamic by driving cylinder 42
Make, at the movable head along the cavity top in mandrel component to plug top, so that movable head is bent, drives the pipe outside movable head
Base bending together is then passed through high pressure gas from the air inlet on ejection seat, and the air pressure for controlling high pressure gas is 0.6~2MPa,
The type chamber of mold is embedded with insert, and forms ripple and be integrally formed in insert, and insert two sides have been arranged radially 6 exhausts
Mouthful, exhaust outlet includes the through-hole 111 that diameter is 0.25mm, and the tool positioned at 111 side of through-hole and with the integrated connection of through-hole 111
Having width is the through slot 112 of 0.1mm, so that during high pressure blow-gas, it can be ensured that the smooth in exhaust at ripple and mold inner-cavity,
The ripple angle sharp corner R increases, and the angle R of sharp corner is R0.45mm at the top of ripple, can reduce wedge angle at mold ripple block to blowing
Pipe during modeling causes to cut, the wall thickness all-the-time stable of pipe, the breakage of ripple when preventing from being blow molded；
Step 5: blow molding tooling is moved together together with the pipe after blow molding to demoulding station, part is detached from from plug,
And the clout on tube body is cleared up, it can be obtained the bellows of TEEE material.
In above-mentioned technique, blow molding tooling includes mandrel component and forming frock, and mandrel component is installed on forming frock, at
Be provided with the cavity of mutual connection in type tooling and mandrel component, ejection assembly by cavity pass through after forming frock with plug
Component cooperation, realizes the bending of molding die inner corrugated pipe embryo, and ejection assembly includes ejection seat 41, driving cylinder 42 and ejection
Bar 43, ejection 41 side of seat have been wholely set air inlet 411, have ejected in seat 41 and be wholely set cavity, knock-pin 43 is threaded through
In the cavity for ejecting seat 41, the end of the knock-pin 43 and driving cylinder 42 link, and mandrel component includes pedestal 31, fixed column
32, movable head 33 and return spring, through-hole has been wholely set inside fixed column 32, and 31 coaxial sleeve of pedestal is set to fixed column 32
Lower end, movable head 33 are articulated with the upper end of fixed column 32, and return spring is set at the delivery position of fixed column 32 and movable head 33,
Movable head 33 has been wholely set oblique angle close to the end of fixed column 32, so that having one between fixed column 32 and movable head 33
The zone of action of angle shape, return spring are fixedly installed on the rear end of the angle zone of action.
In above-mentioned technical proposal, in exhaust outlet structure, the diameter of through-hole can also be 0.15~0.25mm, be located at through-hole one
The through slot width of side and through-hole one connection can also be between 0.1~0.2mm, and the setting quantity of exhaust outlet can be 4~7
It is a.
After the completion of pipe is molded by normal process flow, be inserted on mandrel component by automatic feed mechanism, i.e., it is logical
It crosses mandrel component and internal support is done to pipe, prevent the collapsing of pipe, fold, after suit, pipe is complete on mandrel component
At softening, which drives driven disc to rotate by drive chain, and auxiliary infra red heating device is evenly heated softening to pipe,
After softening, it is correspondingly arranged at the molding die molding of forming frock two sides, while passing through the exhaust in the intracavitary insert of type
Mouthful deep chamber exhaust is carried out, driving cylinder drives knock-pin, from bottom to up along ejection seat, support base, driven disc, pedestal and solid
The cavity of connection goes upward to the lower end surface of movable head in fixed column, and is located on rear side of angle zone of action, with the continuation of knock-pin
Uplink, movable head or along the hinged axial private tutor zone of action rotation in fixed column are set in outside mandrel component to drive
The pipe of side is bent, to realize the bending of the pipe in mold cavity, after the completion of bending, passes through the air inlet on ejection seat
Mouth injects high pressure gas into die cavity, to realize the molding of bending tube, after to be formed, driving cylinder drives knock-pin retraction,
Movable head resets under the action of the return spring, since bending tube cavity after molding is much larger than the size of movable head, return
Bending tube structure is not interfered with when position.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although referring to aforementioned reality
Applying example, invention is explained in detail, for those skilled in the art, still can be to aforementioned each implementation
