Description
Technical field
The present invention relates to a kind of double-deck overall plastic ship rotational moulding manufacture method.
Background technology
Double-deck overall plastic ship refers to the ship for having hollow interlayer hull being combined into by two layers of plastic.It is this by two layers
The hull that what plastics were combined into have hollow interlayer has two kinds of manufacture methods, and one kind is first to mould inside and outside layer hull shell again through split
It is welded, another kind is directly prepared into rotational molding technique.Wherein rotational molding technique mould therefor has inside and outside die body, has on die body and adds
Material mouth, the cavity of a hull shape is formed after inside and outside die body matched moulds.When hull is processed, by the mould in it added with raw materials such as plastics
Have frame on tourelle, mould is heated while rolling, the wherein raw material such as plastics is coated in after melting mixing
Die body inwall, subsequent cooling and demolding obtain the hull of double-deck overall plastic ship.
For the manufacture method of the first double-deck overall plastic hull, obtained individual layer hull shell is semi-finished product, and area compared with
It is big to have deformation unavoidably, it can more cause to deform after two layers of hull shell welding.Simultaneously in order to increase the intensity of hull also need to a rib,
Keel and reinforcement etc. are also welded on hull shell, and these welding can equally cause to deform.Needed for this after welding sequence terminates
Shaping carried out to hull, deformation of hull position can be heated using High jet burner during shaping, then use sand hill, very heavy
The instruments such as top carry out force correction to hull.By the process meeting major injury product quality such as such welding, finishing, mould simultaneously
The various welding of material are unstable with respect to global formation, it is difficult to reach preferable target.
For the manufacture method of second of double-deck overall plastic hull, due to not supported between two layers of housing of double hull,
Hull is caused easily to distort, ectonexine is also easy to that Inward deflection occurs.Simultaneously when rotational moulding is processed, because being entirely by plastics
Flowing come to die surface coat, so being influenceed by factors such as heating-up temperature, mold shape and rotating directions, plastics are spread
Uneven is inevitable, therefore hull shell gage distortion is also inevitable.The thickness of distortion, Inward deflection and hull shell
The thin irregular intensity that will have a strong impact on hull.In the hull obtained by the processing of this technique after demoulding, hull frame, keel etc.
It can not be supplemented between two layers of hull shell, and can only slightly strengthen in hull inner casing inwall composite welding reinforcement
The intensity of hull.Also it has been proposed that after the hull demoulding, filled out to increase the intensity of hull in the hollow interlayer of double hull
Expanded material is filled to increase the intensity of hull.But this behave, which not only wastes material, can not equally reach preferable target.
The content of the invention
For above-mentioned deficiency, the technical problems to be solved by the invention be how when rotational moulding is processed by keel and/or rib
Bone is lining between inside and outside hull, and a kind of the high double-deck overall plastic ship rotational moulding manufacture method of intensity can be manufactured to provide.
The overall plastic ship rotational moulding manufacture method of bilayer provided by the invention, process are after first inside and outside die body is harmonious, then pass through
Charge door adds plastics, reheats and rolling mould makes the raw materials such as plastics melt mixing coated on die body inwall, finally cool down
The demoulding；Wherein before interior external mold is harmonious, first by support frame with support frame fixing device be fixed on interior die body and outer die body it
Between, the distance between the surface of the support frame and inside and outside die body inwall are within hull shell design thickness；The support rib
Frame includes keel and rib, there is up and down that parallel surface, its upper surface are attached in internal model body on wall, support frame lower surface with it is outer
Die body inwall is affixed, and keel and rib form multiple hollow areas with crossbar structure between interior die body and outer die body.
The support frame also includes the reinforcement bone in addition to keel and rib.
The overall plastic ship rotational moulding manufacture method of bilayer provided by the invention, rotational moulding start front support skeleton be already present on by
Between the ectonexine hull shell to be formed, it is connected as a single entity when rotational moulding terminates rear support skeleton with ectonexine hull shell, so as to be formed
The overall support frame with ectonexine hull.And the keel and rib of crossbar structure can shapes between interior die body and outer die body
Into multiple hollow areas.Compared with prior art, there is support frame between ectonexine hull shell of the present invention, compensate for no keel
The defects of with rib Hull Strength deficiency, make hull firm, stably, be unlikely to deform, without the anxiety for being added with amendment, also overcome
It is welded with reinforcement or is taken a lot of work in hollow interlayer caused by filled and process material, takes the defects of material.Meanwhile hollow interlayer is because of dragon
The isolation of bone and rib forms multiple hollow areas, more avoids in case of ruptured just whole hull hollow interlayers at hull shell one
The defects of water inlet.
After the cooling and demolding, the plastics screw being engaged is screwed into the hole that support frame fixing device is left.
Mould used in the overall plastic ship rotational moulding manufacture method of bilayer provided by the invention, there is inside and outside die body, has on die body and adds
Material mouth, inside and outside die body, which is harmonious with being formed, is provided with support frame fixing device on interior die body described in the cavity of a hull shape；Institute
Stating support frame has surface parallel up and down, and after support frame is fixed on interior die body, its upper surface is attached to wall in internal model body
On；After inside and outside die body is harmonious, support frame lower surface is affixed with wall in external mold body, so as to be formed between interior die body and outer die body
Multiple hollow areas；The charge door is arranged on interior die body and respectively opens up one on the region that each is separated out by support frame
Individual charge door, there is charging lid on charge door.
The support frame fixing device is provided in the hole for wearing screw on support frame center line, perforating branches in the hole
The screw of support bone frame, have the tubular projection coaxial with hole on the hole, the tubular projection has external screw thread, separately have with it is described tubular
The internal thread cap of protrusions match, the internal diameter of the cap are less than the tail diameter of the screw, wear the afterbody of screw have it is flat
End face.
The support frame fixing device is provided in the hole for wearing screw of support frame center line both sides, is worn in the hole
The screw of support frame；Separately there is support frame holder, holder is fixed with support frame, also locating dowel, locating dowel one end
Fixed with holder, the locating dowel other end has internal thread, and the screw passes through the hole for wearing screw and the screw-internal thread fit, positioning
Have the pad that height is less than hull thickness of the shell between post and interior die body, the height of locating dowel and pad and hull thickness of the shell with
On.
Said structure is used for the position between fixed screw and interior die body, the keel or rib and internal model fixed to prevent screw
The face being affixed, which is heated, melts（It is soft）Displacement after change.
