Abstract

The invention belongs to a kind of manufacturing process and die device of double bottom glass fiber hull negative and positive mould injection foam integral forming.It comprises by on the negative and positive mould respectively integral body make inside and outside hull, it is had inside and outside hull mould after fixed and close up, and fix, again by foaming mould injecting frothing material in the cavity that inside and outside hull forms by fastener, make it the demoulding after 24 hours, promptly make whole ship.It also comprises a die device, former is installed on the mobilizable fixed mount, and also dispose one with former in the formpiston that matches of cabin physical dimension, have filler opening and deflation hole on the end face of formpiston, it is installed on the fixed mount.The present invention has the production efficiency height, and the cycle is short, is fit to the manufacturing of various ferry glass reinforced plastic boats.

Description

Glass fibre reinforced plastic hull through injecting foam integral forming manufacturing process and die device

The present invention relates to a kind of manufacturing technology of glass double bottom ship, is manufacturing process and die device that a kind of double bottom glass fiber hull negative and positive mould injects foam integral forming specifically., be widely used because of having higher intensity and safety between present glass-felt plastic double bottom ship.Because hull all adopts glass wool cloth and resin to become the glass-felt plastic body after the regular hour solidifying and setting.Therefore, production technology unreasonable not only causes the of poor quality and production cycle of hull own long, but also greatly reduces production efficiency.

The production technology of known existing double bottom glass fiber hull, usually hull outside employing pastes on the former that makes, after fixed typing, put into the end inside rising pouring of shape foaming mould and go into expanded material, treat to revise foam surface again behind the foaming, paste interior hull by foam surface again, twine the demoulding after the fixed moulding in 24 hours, get product.In view of per pass technology in the above-mentioned production process is all wanted 24 hours at interval, it is long that (needing 144 hours from pasting every ship of the finished product demoulding) not only makes the ship production cycle, and be difficult to control and guarantee the stability that physical dimension cooperates in the cabin, the hull rough inner surface causes loss of properties on aging and intensity to reduce in addition.

The purpose of this invention is to provide manufacturing process and the die device of a kind of hull, make it inside and outside hull while global formation, close up, reduced the production cycle, can improve the quality and the production efficiency of ship greatly with matched molds injection foam integral forming.

To achieve these goals, the present invention finishes by following production technology and die device.

A kind of technology of hull global formation is as follows: by on the negative and positive mould of global formation respectively integral body paste out inside and outside hull, its negative and positive mould that has inside and outside hull was closed up together after fixed through 24 hours, fix by fixing device, again by foaming mould injecting frothing material in the folder chamber of inside and outside hull, make it the demoulding after 24 hours, promptly make the finished product ship.

Be used to realize the die device of above-mentioned technology: former is installed in a mobilizable fixed mount, and dispose one with former in the formpiston that matches of cabin physical dimension; Have filler opening and deflation hole on the end face of its formpiston, it is installed on the fixed mount that has push rod.

The present invention has compared to existing technology in the Double bottom cabin that gel coating resin is bright and clean, and the assembling physical dimension is accurate, and any surface finish ageing-resistant performance is good; Close up the back and inject the globality that foaming can improve hull structure, make it Hull Strength and resistance to sinking improves greatly.Hull global formation technology can shorten for 2/3 production cycle, and can to improve work efficiency be 60%.

Describe in further detail in conjunction with process drawing embodiment of the present invention:

Fig. 6 double bottom inner chamber injects the foaming scheme drawing.

Fig. 7 demoulding aftershaping ship scheme drawing.

Fig. 8 ship side closes up place's partial schematic diagram.

See that accompanying drawing 1,2 shows the cross sectional shape of negative and positive mould.Former (1) is placed on the fixed mount (2), center by fixed mount (2) bottom is equipped with movable hinge (3), can make former (1) wallowing motion, the formpiston (4) that physical dimension matches in one of same configuration and former (1) cabin also is arranged on the fixed mount (5) that has a push rod, and on formpiston (4) bottom face, have foaming filler opening (7) and a deflation hole (8), also in the both sides of the fixed mount (1,4) of negative and positive mould fastener (6) is installed respectively, fastener (6) can be nut locking ring or hydraulic efficiency gear.

By Fig. 3, Fig. 4 as can be known, go up whole the paste at negative and positive mould (1,4) earlier and make inside and outside hull (9,10), the reel (16) of after fixed typing in 24 hours, in its hull edge groove, packing into, son is bonding closely knit with composing, the former (1) of the outer hull (10) that will have the formpiston (4) of interior hull (9) again and have closes up, accurate with fastener (6) clamping that fixed mount (2,5) two ends have to guarantee that inside and outside hull (9,10) closes up, see Fig. 5.It is one by screw (11) resin adhesive mortise that inside and outside hull (9,10) closes up the place, seam is loaded onto rubber anti-collision fender (12) after handling with sealant, use bonding jumper (13) nail (14) that it is fixed again, guarantee that intensity and water tightness that hull closes up the place see Fig. 8, again with its foaming mould by foaming filler opening (7) injecting frothing material (17) in the folder chamber of inside and outside hull (9,10), in injection process, should swing die device often, make the air of folder in the chamber by deflation hole (8) discharge, evenly see Fig. 6 with what guarantee injecting frothing material.Treat the demoulding after 24 hours, promptly make finished product ship (15) and see Fig. 7.
