Abstract
The invention relates to a demolding method and forming die for a glass reinforced plastic product and discloses a manufacturing method and forming die of a glass reinforced plastic pipeline and container. The method comprises the following steps of: wrapping the surface of the die with a corrugated board; wrapping the surface of the corrugated board with a polyester film; forming a glass reinforced plastic lining on the surface of the polyester film; integrating the glass reinforced plastic lining and the die into a whole after the glass reinforced plastic lining is cured, rolling the whole on the ground, wherein the corrugated board is pressed to be flat under the action of gravity and the clearance between the glass reinforced plastic lining and the die is increased; pulling the die out of the glass reinforced plastic lining to finish demolding; and forming the glass reinforced plastic pipeline and container by taking the glass reinforced plastic lining as a base. The forming die comprises a mandrel-shaped die body; the surface of the body is wrapped with the corrugated board; and the surface of a surface flat layer is wrapped with the polyester film. The demolding method and the forming die can be used for realizing easy demolding in the manufacturing process of the glass reinforced plastic pipeline and container and is simple to operate, safe and reliable, low in cost and high in efficiency.
Description
Technical field
The present invention relates to a kind of preparation method and mould of glass fiber reinforced plastics product, relate in particular to preparation method and the mould of a kind of GRP pipe and glass steel container.
Background technology
The preparation method of existing GRP pipe and glass steel container generally is: at die surface brushing release materials or the parcel polyester film of mandrel shape, adopt again hand to stick with paste method or winding method formed glass steel GRP pipe or glass steel container thereon, after fiberglass GRP pipe or glass steel container curing, carry out the demoulding.Wherein, the demoulding is an extremely important procedure in the forming process, at present the main mechanical stripping method that adopts.
Behind the GRP pipe curing molding, and seamless between the mould, frictional resistance is large especially, so knockout course is complicated usually, much all adopt hauling machine traction mould, also need simultaneously to be equipped with large specification hydraulic means and push mould, mould and GRP pipe could be separated.Though but this release method safety and stability realizes the demoulding, need the equipment of configuration more, each size pipeline also need dispose different snap rings.In addition, large size pipeline or posted sides pipeline knockout course usually cause the motor of hauling machine or hydraulic test to damage because resistance is excessive.
The demoulding of glass steel container ladle body although without hauling machine or hydraulic means, need a large amount of compressed air to inflate, utilizes air pressure to promote glass steel container and realizes the demoulding.This kind method is because of the pressure that will be subjected in the knockout course about 0.5Mpa, so need the mould of making that smoothness and the extraordinary intensity of high precision will be arranged, the cantilever beam that supporting mould also will be arranged, the cost of manufacture of this mould is very high, and use procedure need to consume equally a large amount of energy and make full-amount compressed air.In addition, knockout course is very dangerous, because in mould and the process that glass steel container separates, form a huge Compressed Gas space, if occur the bonding phenomenon between glass steel container and the mould, can not with mould on when separating, glass steel container blast or die deformation very likely occur to be damaged.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of simple, practical, safe GRP pipe and preparation method and the mould of glass steel container are provided.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
The preparation method of GRP pipe and glass steel container may further comprise the steps:
A. at die surface parcel corrugated board, described corrugated board comprises waveform core paper interlayer and surperficial flat layer, and the thickness of described corrugated board is the 2-4 millimeter;
B. wrap up again polyester film on the corrugated board surface;
C. at polyester film surface formed glass steel lining, described thickness of inner lining is the 3-5 millimeter;
D. after frp lining solidified, frp lining and mould formed an integral body, should integral body roll on the ground, and corrugated board is crushed under Action of Gravity Field, and the gap of frp lining and mould increases;
E. mould is extracted out from frp lining, finished the demoulding;
F. take frp lining as basic formed glass steel conduit and glass steel container.
Corrugated board has certain mechanical strength, the making of energy support glass steel lining in steps d, but the weight of unable supporting mould is crushed in step e, and this just increases greatly with the gap that makes the interior village of fiberglass and mould, thereby makes the very light of demoulding change.In addition, form first the frp lining of 3-5 millimeters thick among the step c, existing disposal molding is to GRP pipe or the easier demoulding of glass steel container desired thickness.
As preferably, among the step c, the method for formed glass steel lining is: be the reinforced plastic glass fibre band of 150-400 mm wide with the reinforced plastic glass fibre combing, the reinforced plastic glass fibre band twined be covered with polyester film surface again.
Use narrower reinforced plastic glass fibre band to twine multi-turn and be covered with polyester film surface, and use wider reinforced plastic glass fibre band to twine a circle to be covered with polyester film surface and to compare, be difficult for excessively to the corrugated board active force, make itself and mould generation relative displacement.
The mould of GRP pipe and glass steel container, comprise mandrel shape die ontology, described body be coated with corrugated board, described corrugated board comprises waveform core paper interlayer and surperficial flat layer, the thickness of described corrugated board is the 2-4 millimeter, described surperficial flat layer be coated with polyester film.
The waveform core paper interlayer of corrugated board is that certain space has been reserved in the demoulding.During the demoulding, mold integral is rolled on the ground, corrugated board is crushed under Action of Gravity Field, and the space that waveform core paper interlayer is reserved is released, and this moment, mould can be extracted out easily, finished the demoulding.
According to technical scheme of the present invention, GRP pipe and the easily demoulding of glass steel container manufacturing process; Need not hauling machine and liquid level control system push-and-pull mould, save power cost and maintenance of equipment cost; Need not pressurized, make simply, cheap, and knockout course can not block, and avoided excessive end socket blast or the mould depressed phenomenon that causes of conventional air pressure, safe and feasible.
