Conduit model head. Unoccupied place to the model of circular model head the tubal capable person that a ply of different tube wall pushs below the condition that the adjustment that undertakes essence of life allows is not changing technological process. All manufacturer tubal material have a such desires: Can use simple " balata model head " material is provided in what do not interrupt the case that presses a product line operation to fall to be able to make a random provide diameter and thickness of aleatoric tube wall, but such desire cannot come true possibly forever. What what I hope is now had had be close to the solution at this kind of good position very much. Produces figure tubal material is more complex, so the manufacturing cost of the mould and craft level are more complex also. Below a lot of circumstances, if the model of modular head is unoccupied place,can undertake simply modulatory, can have brought very large production dominant position so (it is at least inside certain limits, constant mould diameter) , this kind of design can produce the tubal material of ply of different tube wall. A kind of good model is unoccupied place adjust the method is to make mould and calibration the molecular orientaton between keeps low and orderly, get the smallest shrinkage thereby. Of course, optimal condition is this additional technology design does not need to use a kind of complex model head structure and the operation that destroy whole and safeguard. The pull current Cheng that watchs traditional pattern tubal material instead when us, very difficult imagination uses to be able to facilitate operation and the modular head opposite that clean produce operation flow to make be adjustmented simply can get a hopeful result merely. This perhaps is head of this kind of model does not have the reason that come out till now. Tilt the technology is for can more a kind of when essence of life allows and undertake specificly adjust and be creatinged going out to modular head new frontier unoccupied place technology, it can is opposite very simply the model is unoccupied place undertake adjustment. Tilt the technology was used tilt technology, use high temperature resistant the aperture between head of model of join of balata sealing ring and mould (see a picture 1) . The mould can undertake declining now and not be to pass shift gears to aim mould and core club. This kind of technology and traditional metallic canal are sealed photograph comparing can offer a lot of decisive advantages. Because the mould does not need to be made a round trip again,the ground moves, OK and close together ground joins together between mould and modular head, because this mould needs installation only,be in a center can (see a picture 2) . The modular head cleanness that also can avoid to undertake at present most mould place must undertake works. To assure to tilt sealed have abiding pressure to need a reliable sealing ring, it still has an assembly parts of simple type blocking an opening. Different tube wall ply is OK through tilting the mould undertakes operating. This kind of mode of operation is in to transfer now level, the adjustment screw that can use an axial to arrange will undertake operating (see a picture 3) . This kind of mode of operation can be in for certain greatly be replaced by the means place of a kind of mechanization gradually in the future. The advantage of mechanization calibration depends on a mould can using mechanical Control Panel to undertake very exact location is operated at the beginning. This also can optimize fixed position at the same time, once discover an error, we can undertake accurate reproduction in any time. After undertaking cleanness to modular head, the mould can return the place that operates last time accurately. In the process that Nextpage blows model figuration in extruding, the regulating system of a motor-driven can make although the mould goes out in orderly ground discharge model still can undertake trends tilts below the circumstance of embryo. The different drawing ratio of the wall outside when for instance it is making bent tubing, be being mixed considering conduit wall (see a picture 4) , in the process that tilts in the mould, that a side that stretch sealing ring can reduce in modular unoccupied place need gets more pressure, and the passageway meets the fluid of another side to wait for a quantity accordingly increase at the same time. Tilt the weakness that mould technology overcame traditional centering to handle a technology not only, and also simplified the production of annular mould, reduced manufacturing cost. Once overcame the stretch sealing ring that experts care generally cannot conformity arrives crowded piece model the problem in mould flow path, the stretch index that what next need does on logic is pair of sealing ring has research and development, undertake adjustment making it makes an organic whole completely with modular head to the mould. And if this one principle is broken later the mould must have to uninstall an area parallelly in the extreme of flow path, can be opposite so the model is unoccupied place undertake modulatory. The production that a clear advantage is modular head should be gotten simply compared with the foregone process that blows the place in model figuration to use in extruding much. Although the blemish with constant presence is returned on craft processing, but model is blown in extruding modular head and cone-shaped core club and cone-shaped mouth model are used to have a model in order to facilitate in figuration unoccupied place adjusted practice is very common still. Because marvellous or so cone-shaped core is cone-shaped,buccal model can be inside definitive distance the campaign that has axial. Certain leakage material also can be accepted, because modular head of motion must be in,one has the circumstance that adjusts surplus certainly to fall to have campaign around Kong Xin. If need to change the aperture of tube head, changing cylindrical need to use club of a cone-shaped core to be able to come true only below the circumstance of the mould. The adjustable limits of this aperture will depend on the cone angle with cone-shaped core pointed club, and tilt the largest mobile space that seals a circle to be able to be achieved. Axial is adjustable type pattern is same to external diameter adjacent perhaps conduit, the bandwidth that place of good tube wall ply requires is quite small. In be operated actually, mere the canal that the mobile distance of a few millimeter can satisfy place to need is unoccupied place. If tilt,sealing ring is designed a bit a few more thickly, so sealing ring can bear greater pressure, from preload level can get better sealed result. This can come true through using a simple whorl sealing ring. What the graph shows 5 times is this is planted compositive tilt contact and model are unoccupied place adjust functional mould. The bolt of 4 axial calibration of use mould surface can adjust of the mould tilt extent, and can immediate effect the flange annulus at the mould. Fixed screw is used to undertake fixed between modular head coping and modular head, and use whorl pressing annulus use at moving the width of section flow path as the screw that move a heart, in addition, how to still cover of resilient ring on modular head. The adjustment that radiative shape arranges bolt can use tone to make flow path crack, fall the wave motion of asymmetry of tube wall ply lowermost limit. Accordingly, more essence of life allows more advanced centering technology, and use resilient ring covers those who undertake flow path to adjust, the tube wall ply that before can be being achieved, cannot come true. What the picture of caption shows is the mould in moving. The modular head of this kind of new design also is simplify maintenance respect set new standard. Beyond the characteristic that eliminate aperture adjusts, the modular head of this kind of mould does not need to get off to be able to undertake be cleaninged thoroughly from extruder. The main body screw between brainpan of loose fixed die and modular head, modular brainpan can get off completely, can undertake cleaning to whole flow path. In cleaning a process, the main body of the mould still holds connective position with extruder. The application of eye pitch inclined technology still has limitation. Because mix the wearability of stretch material,can't bear have caustic compound to invade. However, after sealed substitute experiment gains a success, this problem tilts in the following metal also can be overcome. CNC MillingCNC Machining
