Description
Technical field
The invention belongs to modeling technique field, it is related to the modeling method and mold ship bracket of a kind of hull bottom model.
Background technology
The means of transport such as ship or automobile is built to generally require to manufacture one to one physical model first.That is master body,
Or " master cast " is called, the mould of sheet metal part processed is thus turned over again.The development progress and precision of a kind of product, depending on standard
The processing of entity, master cast.Because standards entities, the ground of master cast one to one reflects that the general assembly of covering and each component is closed
System is manufacture and reprocesses the foundation of various moulds and assembling jig, and sheet metal part manufacture is exchanged with coordinating.People are to standard
Entity, the processing of master cast, pours into research interest.In standards entities, the existing processing technology of master cast, made with epoxy resin
Adhesive, all complex process, not easy to be processed, of high cost, production cycle are grown mostly.Particularly with epoxy resin as adhesive
Plastic processing, due to using mineral matter in a large proportion as filler, it is small, crisp that this makes the processing of plastic mould intensity height, toughness occur
The disadvantage that property is big, machining property is poor.
The content of the invention
For such case, the present invention provides the modeling method and mold ship bracket of a kind of hull bottom model, it can be right
Bottom of ship carries out mold and the demoulding, including mold ship bracket and the miscellaneous bed of material carry out epoxy resin batch mixing moulding, then pass through ship
Bed die tool to epoxy resin batch mixing carry out pressing mold forms new ship bracket, can from ship bracket hull integrality, for
Building hull bottom has good test effect.The adjustment that the present invention is modeled for hull bottom of different shapes, and air-drying device can
To accelerate the molding time of mould, cleaning device can clean equipment automatically；With the variation of moulding effect, easy to operate,
The characteristics of novel.
The technical scheme is that：
A kind of modeling method of hull bottom model, comprises the following steps:
Step 1, places the good large-scale plastic cloth of leakproofness, the surrounding gear of the plastic cloth on mold ship bracket
Block and fluid sealant are fixedly mounted on the frame of mold ship bracket；
Step 2, is paved with least two layers of plastic thin films on the plastic cloth, then at least two are spread on the plastic film
The material that layer kapok, shredded paper and flexible chain break forms the miscellaneous bed of material, and spreads plastic film in the top of the miscellaneous bed of material；
Step 3, is put into the hull bottom mould for treating mold, and the hydraulic pressure on mold ship bracket is adjusted according to the bottom shape of hull bottom mould
Device height, while coordinate limiting steering device to establish the blank of a hull bottom bottom shape, mold ship bracket is adjusted to ship
The hull bottom mould for treating mold is taken out after bottom bottom profile and lines；Then inserts smearing release agent is pacified inserts with after preheating
It is attached on the correspondence position for needing setting preformed hole of mold ship bracket；
Step 4, prepares epoxy resin batch mixing：
First, epoxy resin is put into material-compound tank and carries out heating melting stirring, when the epoxy resin reaches predetermined temperature,
It is sent into degassing tank and is de-gassed after filler is produced with the epoxy resin uniform stirring after melting to not a large amount of foams, then
Pour into a vacuum tank and be sufficiently mixed, and add defoamer and carry out deaeration processing；Secondly, curing agent is carried out heating to melt
Melt processing, then the epoxy resin after curing agent and batch mixing is sufficiently mixed, obtain epoxy resin batch mixing, be ready for pourer
Make；
Step 5, the good mold ship bracket casting epoxy resin batch mixing of place mat into step 3, then on epoxy resin batch mixing
At least it is laid with layer of plastic film；
Step 6, the hull bottom mould for treating mold are preheated, and the hull bottom mould after preheating is smeared de- after being wrapped up with plastic film
Mould agent；Then it is pressed into the epoxy resin batch mixing of step 5, mold curing and the demoulding is carried out to epoxy resin batch mixing；The demoulding
Secondary curing, mechanical processing and inspection are carried out afterwards, obtain epoxy resin hull bottom model；The epoxy resin hull bottom mold curing
It is made of afterwards in its surface smear self-cleaning waterborne epoxy coatings, its described self-cleaning waterborne epoxy coatings two component of A, B, its
Respectively form by mass content number and be：
Component A：32~34 parts of aqueous epoxy curing agent；18~13 parts of rutile type titanium white；9~5 parts of barium sulfate；JTC-305
8~4 parts of type polytetrafluoroethylene powder；Fluorine-containing 6~4 parts of toughener；0.25~0.2 part of A10 types defoamer；2020 type levelling agents 0.25

B component：32~34 parts of aqueous epoxy resin emulsion, 296DS types benzene/5~3 parts of acrylic emulsion.
According to the hydraulic device height on the Adjusting Shape mold ship bracket of required modeling, while coordinate limiting steering device
The blank of a bottom die is established, the bottom profile and lines of established model are treated according to different demands adjustment；Carried out again after mold
Cure and demould；Secondary curing, mechanical processing and inspection are carried out after the demoulding.Base-material and a certain amount of curing agent are uniformly mixed,
Pour into module, under 50 DEG C to 60 DEG C of environment temperature, by 8 when small more than curing molding, then in the environment of room temperature
It is lower to place more than 7 days, then demould and sample is made according to size requirement；The cast of gasket is according to axial center position, estimation
The thickness of gasket is poured into a mould usually in the range of 15mm to 70mm, generally 25mm to 45mm, can laminated pouring more than 50mm.
As further technological improvement, then above-described epoxy resin uniform stirring adds filler mixing to 65 DEG C,
Then add curing agent mixing；The epoxy resin is with filler according to 1:1.2 ratio is mixed evenly to after 70 DEG C
Batch mixing is sent into degassing tank and is de-gassed；Pressure is 0.11 kPa in the degassing tank, and the degassing time is small for 3
When；When the time that the batch mixing is pumped into degassing tank is small no more than 4.Before cast, curing agent is poured into the bucket equipped with base-material, is stirred
Mix uniformly, avoid bubble；Epoxy resin mixes the time that must be noted that degassing when being de-gassed with filler, can be made when small more than 4
