Specific embodiment
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that specific embodiment described herein is merely to illustrate and explains the present invention, the present invention is not limited to.
In the present invention, in the case where contrary explanation is not made, be if the noun of locality for using such as " inside and outside " for accompanying drawing corresponding component profile it is inner and outer for.
As shown in Figure 1, the present invention provides a kind of mould of profiled member, wherein, profiled member can be automotive trim, it can also be automobile exterior, the mould includes die ontology 1, and the die ontology 1 has the through hole 4 that connection internal cavities 3 and contoured outer surface 5 are also formed with contoured outer surface 5 and internal cavities 3, and die ontology 1.Because the die ontology 1 of the mould of present invention offer has contoured outer surface 5 and internal cavities 3, mould structure is simple, is conducive to shortening the fabrication cycle of mould and can reducing cost of manufacture.In addition, due to through hole 4, only need to be by way of the evacuation of cavity 3 internally, can realize that the fabric of profiled member is attached on contoured outer surface 5 and molding, the purpose for quickly realizing profiled member molding can be reached by this vacuum adsorption molding mode, for verifying the feasibility of product design scheme and can be good at solving the problems, such as that design verification is changed.
It should be noted that can realize that the embodiment that foregoing invention is conceived has various, structure design of such as profiled member etc., it is of the invention for convenience of explanation, preferred implementation therein is introduced at this, the preferred implementation is served only for the explanation present invention, is not limited to the present invention.
In a preferred embodiment of the invention, in order to realize the quick Fabrication of mould body 1, preferably, die ontology 1 is obtained by the expanded material or substitute materials for wood of hard, wherein, generation wood is usually to be produced with unsaturated-resin, glass microsphere powder is added in unsaturated-resin, add firming agent, air inside extraction, its solidification is made so as to generate, and it is more preferable to compare soft mold toughness using the expanded material or substitute materials for wood of hard polyaminoester, stability is higher, it is more environmentally friendly, it is relatively more suitable for doing cubing, fixture, the higher product of tool equally accurate, while the molding that good toughness is also beneficial to die ontology 1 is unlikely to deform.And the wall thickness of die ontology 1 can also determine as needed, typically more than 50mm is scheduled on after machining, the modification after verifying can be so easy to, modification scope is than larger, it is unrestricted, and soft mold is adopted before comparing, the generally more than change of 10mm is irrealizable, and change limitation is very big.In addition, additionally it is possible to reduce the cost and fabrication cycle for making die ontology 1.
Further, for the hollow design of the internal cavities 3 for realizing die ontology 1, in a preferred embodiment of the invention, die ontology 1 can be formed by least two pieces of template splicing, central cavity is formed, for example, as shown in Figure 1, die ontology 1 includes upper and lower two pieces of templates, such that it is able to be spliced into the mould with internal cavities 3.In addition, open up on the contoured outer surface 5 of die ontology 1 in order to the aperture of multiple through holes 4 of ventilation is preferably provided between 1-4mm, aperture can be avoided excessive ineffective, simultaneously through hole 4 according to the complex degree of structure of the contoured outer surface 5 of die ontology 1 come providing holes away from, pitch-row can suitably be reduced i.e. at complex structure position, the effect of through hole 4 is more efficiently realized.
The mould of present invention offer is be provided, in order to finally realize using mould to make profiled member, the present invention also provides a kind of formation system of profiled member, and the formation system also includes the evacuator for connecting with above-mentioned internal cavities 3 except above-mentioned mould is included.The evacuator is used to carry out evacuation to internal cavities 3, to reach the purpose of the molding of die ontology 1.That is, the process to the molding of die ontology 1 is completed using existing evacuator, in other words, the present invention can further complete the forming method to present invention offer by the utilization to evacuator.As shown in figure 1, the concrete forming method that the present invention is provided is as follows：
In the first step, airtight fabric 2 is laid on the contoured outer surface 5 of die ontology 1 first；Wherein, airtight fabric 2 used adopts polrvinyl chloride (PVC), polrvinyl chloride (PVC) it is formability thereof strong, toughness is preferable, in addition the air-locked property of polrvinyl chloride (PVC) so as to can adsorb laminating on through hole 4, realizes being fitted with contoured outer surface 5.
In the second step, by the evacuation of internal cavities 3 of die ontology 1, airtight fabric 2 is made to be adsorbed on contoured outer surface 5；Using above-mentioned vacuum extractor by the vacuum state of internal cavities 3, so that airtight fabric 2 can fit completely being adsorbed onto on contoured outer surface 5.
In third step, the brushing curing materials on airtight fabric 2 are obtained profiled member after the curing materials solidification.Preferably, curing materials can be fiber glass resin material, fiber glass resin is made after being heating and curing by glass fibre and mixed with resin, well curing molding can be carried out to airtight fabric 2, and should be greater than 24h the hardening times of curing materials, so solidifying the profiled member for compares firm and durable, and the profiled member being cured can also by hand remove excess material, finishing completes the making of profiled member, for verifying the feasibility of the design of product.The short molding cycle of profiled member made by so, it is convenient and swift, the feasibility of product design scheme can be verified with this.
To sum up, the present invention provide profiled member mould and using the mould profiled member the molding decorum and method, for the clever structure of die ontology 1, it is reasonable in design, so that mould cost itself is relatively low, fabrication cycle shortens, in addition, moulding technique using the profiled member after the mould is simple, in addition it is and less demanding to the selection in place, it is convenient and swift, profiled member to verify the feasibility of product design scheme and can be good at solving the problems, such as that design verification is changed, it is particularly practical suitable for automotive trims such as forming platfonds, so with higher practicality and promotional value.
The preferred embodiment of the present invention is described in detail above in association with accompanying drawing; but; the present invention is not limited to the detail in above-mentioned embodiment; in the range of the technology design of the present invention; various simple variants can be carried out to technical scheme, these simple variants belong to protection scope of the present invention.
It is further to note that, each particular technique feature described in above-mentioned specific embodiment, in the case of reconcilable, can be combined by any suitable means, in order to avoid unnecessary repetition, the present invention is no longer separately illustrated to various possible compound modes.
Additionally, can also carry out combination in any between a variety of embodiments of the present invention, as long as it is without prejudice to the thought of the present invention, it should equally be considered as content disclosed in this invention.
