Abstract
The utility model relates to a forming die for fibre reinforced plastic products, and discloses a forming die for a fibre reinforced plastic pipeline and a fibre reinforced plastic container. The forming die comprises a spindle-shaped die body, wherein a corrugated paper board is wrapped on the surface of the body; the corrugated paper board comprises a wave-shaped core paper interlayer and a surface flat-board layer; the corrugated paper board is 2-4 mm in thickness; and a polyester film is wrapped on the surface of the surface flat-board layer. The forming die disclosed by the utility model realizes easy die release in production processes for a fibre reinforced plastic pipeline and a fibre reinforced plastic container, and is simple to operate, safe and reliable, low in cost, and high in efficiency.
Description
Technical field
The utility model relates to a kind of mould of glass fiber reinforced plastics product, relates in particular to 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 utility model provides a kind of simple, practical, safe GRP pipe and the mould of glass steel container for deficiency of the prior art.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
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 the technical solution of the utility model, 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.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the enlarged diagram of A section among Fig. 1.
The specific embodiment
The below is described in further detail the utility model:
Embodiment
The mould of GRP pipe and glass steel container, comprise mandrel shape die ontology 1, described body 1 be coated with corrugated board 2, described corrugated board comprises waveform core paper interlayer 21 and surperficial flat layer 22, the thickness of described corrugated board is 3 millimeters, described surperficial flat layer 22 be coated with polyester film 3, the diameter of described die ontology 1 is greater than 800 millimeters.
Use above-mentioned mould to make the method for GRP pipe and glass steel container, may further comprise the steps:
A. be the reinforced plastic glass fibre band of 300 mm wides with the reinforced plastic glass fibre combing, again the winding of reinforced plastic glass fibre band be covered with polyester film surface, form frp lining, described thickness of inner lining is the 3-5 millimeter;
B. 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;
C. mould is extracted out from frp lining, finished the demoulding;
D. 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, but the weight of unable supporting mould is crushed in step b, 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 a, existing disposal molding is to GRP pipe or the easier demoulding of glass steel container desired thickness.
Use the narrower reinforced plastic glass fibre band of 300 millimeter to twine multi-turn and be covered with polyester film surface, with 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.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
Claims (1)
1. the mould of GRP pipe and glass steel container, comprise mandrel shape die ontology, it is characterized in that: 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.
