Description
Technical field
The present invention relates to a kind of system using variable cross-section mandrel manufacture belt type cavity product, which is especially suitable for
It applies in the pultrude process of the fibre reinforced composites of manufacture such as polyurethane etc.
Background technique
There is quite a few product to have one or more type chambers in pultrusion product.The pultrusion product of belt type cavity is producing
It not only needs using mold in the process, it is also necessary to use mandrel and corresponding fiber impregnation system.Therefore, traditional manufacture banding pattern
The system of chamber product is all made of that mandrel is fixed and the position of mandrel is adjusted in regulating device.
Fig. 1 shows a kind of system for manufacturing belt type cavity product common in the art.Since on the left of Fig. 1
Mandrel is disposed with to fix and regulating device 5, fiber impregnation system 3 and mold 1.Mandrel is fixed and regulating device 5, fiber impregnation system
System 3 and mold 1 are us shown firmly attached on mould bases 2 each by least one fastener, wherein mandrel is fixed and regulating device 5
Direction along mould bases 2 is moveable.The mandrel 4 of constant dimension passes through each two adjusting screws 9 up and down along its length
Mandrel is fixed on to fix and regulating device 5.The upper and lower of mandrel or left and right translation may be implemented in these adjusting screws 9, thus to core
Center position of the axis 4 in mold 1 is adjusted.System operation when, mandrel 4 pass through mandrel fix and regulating device 5 it
Afterwards, the access panel 8 of fiber impregnation system 3 is continued through, is finally reached inside mold 1, so that pitch based fiber is solid
It is melted into profile 7.It is additionally provided at least one lock screw 6 in the tail portion of mandrel 4, to prevent mandrel 4 in process of production because of external force
It acts on and is pulled.
In the product of belt type cavity, the type chamber of quite a few product is very small.That is, this product institute
With the size of mandrel also very little.Small size mandrel is easy to lead to product wall thickness not due to the shake and deformation in operating process
, and it will increase pultrusion pulling force.
In addition, have in many pultrusion products containing there are two even more than type chamber, this in actual operation need to set two
Root or more mandrels.The stabilization of relative position between these mandrels and accurate and they are relative to mould intracavity wall phase
To the stabilization of position and accurately for most important for the uniformity and accuracy of pultrusion product cavity wall thickness.But this
Be in practical operation it is difficult to realize, especially can be more difficult when type chamber very little.
In compound polyurethane material pultrusion molding process, due to polyurethane to moisture sensitive and the operating time it is very short, lead to
What is be often used is closed fiber impregnation system (such as syringe case), and such mandrel must be just suspended in syringe case and mold,
It is longer than mandrel length used in common pultrude process so as to cause the length of mandrel, it further increases and keeps mandrel
Stable and pinpoint difficulty.Such long mandrel is deposited in various aspects such as processing and manufacturing, installing and dismounting and maintenances
In all difficulties.
Therefore, it is badly in need of the system for researching and developing a kind of improved manufacture belt type cavity product at present.Even if the cavity dimension of product compared with
Small or product has multiple type chambers, which can also prevent mandrel from occurring to shake in operation and deform, to protect
Demonstrate,prove the uniform wall thickness of product and accurate.
Summary of the invention
The purpose of the present invention is to provide a kind of systems for improved manufacture belt type cavity product.Even if the type chamber of product
Size is smaller or product has multiple type chambers, which can also prevent mandrel from occurring to shake in operation and deform,
To guarantee the uniform wall thickness of product and accurate.
The present invention relates to a kind of system for manufacturing belt type cavity product, the system include mandrel fix and regulating device,
Mandrel, fiber impregnation system and mold, the mandrel pass through fiber impregnation system and solidify pitch based fiber in mold

Access panel 8 finally reaches inside mold 1, so that pitch based fiber is solidified into profile 7.In the tail of variable cross-section mandrel group 40
Portion is additionally provided at least one lock screw 6, to prevent variable cross-section mandrel group 40 from being pulled in process of production because of external force.
Variable cross-section mandrel group 40 fixed central spindle and can adjust the positions of different mandrels simultaneously at mandrel integrated package 10, can also pass through
The relative position at different mandrels and mandrel integrated package 10 is adjusted to be independently adjustable position of each mandrel relative to product type chamber
It sets.
Size of each mandrel at entrance mold 1 is consistent with the shape of product type chamber in variable cross-section mandrel group 40, and
At least part except mold 1 or specifically in mandrel fix and regulating device 5 and fiber impregnation system 3 between extremely
Few a part has the shape of continous way amplification and/or staged amplification.Variable cross-section mandrel group 40 can integrally be made with time processing
At can also be connected and composed by two or two or more mandrels by screw thread, sleeve or other well known mode.
(referring to Fig. 6) for producing the small cavity product of three type chamber of thin-walled, three mandrels are entering the size at mold 1
It is consistent with product type chamber, that is, be 11mm × 6mm, and mandrel fix and regulating device 5 and fiber impregnation system 3 between extremely
Few a part is linked together three mandrels by mandrel integrated package 10, and wherein the two of two sides piece mandrel is gradually amplified to 50mm
× 30mm, intermediate mandrel are gradually amplified to 11mm × 30mm.In addition, mandrel group 40 is at syringe case outlet end and in syringe case
The second gap between chamber is 2.2mm, and the first gap at syringe case entry position between syringe case inner cavity is 2mm.
By above-mentioned setting, mandrel integrated package 10 is adjusted by mandrel and fixed device 5 is firmly suspended in mold 1.It was producing
Cheng Zhong can translate mandrel integrated package 10 by 9 up and down or left and right of adjusting screw if the wall thickness of profile 7 changes, from
And realize the adjusting of product wall thickness.
Variable cross-section mandrel as described above is not only applicable to common open fiber impregnation system, is also applied for closed
Fiber impregnation system, such as low-pressure glue-injection system and high-pressure injection plastic system.It, can be in syringe case when using high-pressure injection plastic system
Entry position at increase sealing device, leaked from syringe case to avoid resin.
Although the quantity of type chamber and mandrel is set as three in this example, the quantity of type chamber also can change, and
And the mandrel of identical quantity is integrated according to the quantity of type chamber.Other than the shape that continous way and staged are amplified, mandrel can also
To have shape or its shape being combined with each other with other variable cross-sections that continous way and staged are combined.These become
Change will all be fallen within scope of the present invention.
The applicable resin of system of the invention includes but is not limited to heat-curable urethane, epoxy resin, vinylite, no
The thermoplastic resins such as the thermosetting resins such as saturated resin and thermoplastic polyurethane, polycarbonate, polypropylene, nylon.Of the invention
The applicable fiber of system includes but is not limited to glass fibre, carbon fiber, basalt fibre etc..
Although combining preferred embodiment above to say the structure of the system of manufacture belt type cavity product of the invention
It is bright, but those of ordinary skill in the art is it should be appreciated that above-mentioned example is intended merely to explanation, and cannot function as
Limitation of the present invention.Therefore, modification can be carried out to the present invention in the spirit of claims.These modifications
Within the scope of all falling in required by claims of the present invention.
