---owing to constitute the cylindrical mould of the mould of this variable diameter glass fibre reinforced plastic pipeline is isolating construction, and between the position adjustment of can sliding, promptly can adjust the length of variable diameter glass fibre reinforced plastic pipeline indentical tube road section as required, therefore, can use a mold to prepare the variable diameter glass fibre reinforced plastic of different size, the utilization rate that has improved mould has greatly reduced production cost
---utilize the mould of this preparation variable diameter glass fibre reinforced plastic pipeline can directly prepare no seam, incorporate variable diameter glass fibre reinforced plastic pipeline, no matter this variable diameter glass fibre reinforced plastic pipeline is on the pipeline or the reducing place does not all have the seam appearance, therefore, the variable diameter glass fibre reinforced plastic pipeline of being produced has the advantages that seepage and long service life can not appear in material unanimity, mechanical strength properties unanimity, reducing place pipeline;
Description of drawings
Fig. 1: be the structural representation of mould of preparation variable diameter glass fibre reinforced plastic pipeline;
Fig. 2: be the structural representation of fixed disk in the described mould of Fig. 1;
Fig. 3: be the deceleration column end structure schematic diagram of cylindrical mould in the mould that constitutes variable diameter glass fibre reinforced plastic pipeline.
The specific embodiment
Be described in further detail below in conjunction with the structure of accompanying drawing the mould of preparation variable diameter glass fibre reinforced plastic pipeline provided by the present invention.
As shown in Figure 1, be the structural representation of the mould of preparation variable diameter glass fibre reinforced plastic pipeline provided by the present invention.Its structure includes an elongated rotating shaft 4 that can be driven its rotation by motor, gear 12 that rides on the die frame 6, is with three cylindrical moulds 1,2 and 3 in this rotating shaft, and this cylindrical mould is made of the structure that deceleration column 7 and end are taper type 5; Wherein the frustum mouth of first cylindrical mould 1 is set in the rotating shaft 4, and the second and the 3rd cylindrical mould 2 and 3 frustum mouth are set on respectively on the deceleration column of first and second cylindrical moulds 1,2, and the other end of above-mentioned three cylindrical moulds and rotating shaft be relative fixed respectively; In the structure of above-mentioned cylindrical mould, the second and the 3rd cylindrical mould 2 and 3 frustum mouth can slide in the outside wall surface of first and second cylindrical moulds, be used to adjust the length at cylindrical mould deceleration column position.
When utilizing this mould to prepare variable diameter glass fibre reinforced plastic pipeline,, adjust the position of corresponding cylindrical mould, to determine the length of its deceleration column according to the length of each different tube diameters pipe in the variable diameter glass fibre reinforced plastic pipeline; Then with cylindrical mould and rotating shaft relative fixed.Start actuating unit and drive its rotating shaft rotation, the uniform winding glass-reinforced plastic material can form needed variable diameter glass fibre reinforced plastic pipeline on mould.
In the structure of the mould of above-mentioned variable diameter glass fibre reinforced plastic pipeline, can set the number of cylindrical mould as required, and change the cylindrical mould of different-diameter, and the frustum muzzle of a back cylindrical mould is got final product on the deceleration column of previous cylindrical mould according to different needs.
