Abstract
The utility model relates to a mould for manufacturing fiber reinforced plastic pipes, which comprises a cylinder. A strip-shaped gap running through the cylinder is arranged on the cylinder; a filling strip which has the same shape as the strip-shaped gap is arranged in the strip-shaped gap; a driving device for driving the filling strip to extend is arranged in the cylinder; one end of the driving device is connected with the inner wall of the cylinder, and the other end is connected with the filling strip. When the mould for manufacturing the fiber reinforced plastic pipes is in use, the cylinder can be manufactured according to the nominal diameters of the fiber reinforced plastic pipes, and because the mould has no conicity, the areas of the actual flow sections of the manufactured fiber reinforced plastic pipes can not be reduced.
Description
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of mfg. moulding die of glass reinforced plastic pipe.
Background technology
In the prior art; Producing the employed mould of glass reinforced plastic pipe, be to make a formwork for cylindrical columns that has certain taper according to the nominal diameter of glass reinforced plastic pipe, and needed glass reinforced plastic pipe is processed in winding above that; After glass reinforced plastic pipe solidifies, utilize special-purpose demoulding equipment to carry out the demoulding again.Because the tapering of mould is very little, thereby need very big demoulding active force could glass reinforced plastic pipe be separated with formwork for cylindrical columns.Simultaneously this kind mould the cost of supporting special-purpose demoulding equipment very expensive, and efficient is very low.In addition, because mould has tapering, make the area in actual circulation cross section of the glass reinforced plastic pipe produce reduce 0.6% with the glass reinforced plastic pipe that utilizes band tapering die production to come out, it is more that the less glass reinforced plastic pipe of nominal diameter reduces.
The utility model content
The purpose of the utility model is the existing defective of mould of producing glass reinforced plastic pipe in the prior art in order to solve, and provides a kind of mfg. moulding die of glass reinforced plastic pipe to solve the problems referred to above.
To achieve these goals, the technical scheme of the utility model is following:
A kind of mfg. moulding die of glass reinforced plastic pipe; Comprise cylinder, it is characterized in that the top of said cylinder is provided with the rectangular longitudinally slit of running through cylinder; Be provided with the packing identical in the rectangular slit with the shape in rectangular slit; Also be provided with the flexible drive unit that drives packing in the said cylinder, an end of said drive unit connects cylinder inner wall, and the other end of drive unit connects packing.
The mfg. moulding die of above-mentioned a kind of glass reinforced plastic pipe is characterized in that, the width of the upper end in said packing and rectangular slit is greater than the width of lower end.
The mfg. moulding die of above-mentioned a kind of glass reinforced plastic pipe is characterized in that, said drive unit comprises oil cylinder and push rod, and oil cylinder drives push rod and moves up and down, and push rod connects packing.
The beneficial effect that the utlity model has: can make cylinder according to the nominal diameter of glass reinforced plastic pipe during use, because mould does not have tapering, the actual circulation sectional area of the feasible glass reinforced plastic pipe of producing can not reduce.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the profile of A-A among Fig. 1.
The specific embodiment
For making architectural feature of the utility model and the effect of being reached there are further understanding and understanding, cooperate detailed explanation, explain as follows in order to preferred embodiment and accompanying drawing:
Referring to Fig. 1 and Fig. 2; A kind of mfg. moulding die of glass reinforced plastic pipe comprises cylinder 100, and the top of cylinder 100 is provided with the rectangular longitudinally slit 110 of running through cylinder 100; Be provided with the packing 200 identical in the rectangular slit 110 with the shape in rectangular slit 110; Also be provided with the flexible drive unit 300 that drives packing 200 in the cylinder 100, an end of drive unit 300 connects cylinder 100 inwalls, and the other end of drive unit 300 connects packing 200.
The structure in packing 200 and rectangular slit 110 all is the width of upper end width greater than the lower end, and making packing 200 be stuck in the rectangular slit 110 like this can extract packing 200 out downwards.
Can make cylinder according to the nominal diameter of glass reinforced plastic pipe during use, because mould does not have tapering, the actual circulation sectional area of the feasible glass reinforced plastic pipe of producing can not reduce.
In sum; Be merely the preferred embodiment of the utility model; Be not to be used for limiting the scope that the utility model is implemented; All equalizations of doing according to the described shape of the utility model claim scope, structure, characteristic and spirit change and modify, and all should be included in the claim scope of the utility model.
