Embodiment Construction
[0020] Examples of mold components used in the FRP wet winding process are Figure 1~3 As shown: it includes forming rollers 10 for forming corresponding glass fibers and supporting shafts 11 arranged at both ends of the forming rollers 10, and the supporting shafts 11 can drive the forming rollers 10 to rotate under the drive of corresponding driving mechanisms. Each support shaft is fitted with a mold tooling adapted to the forming roller. The mold tooling includes a roller joint 9 made of iron. The roller joint 9 is provided with a fixed connection structure that makes it relatively fixed to the forming roller during use. The roller joint 9 includes an upper joint 1 and a lower joint 4 that are assembled together up and down. The outer circumference of the upper joint 1 has an arc surface 1-1 on the outer circumference of the joint, and the outer circumference of the lower joint 4 has an arc surface 1-1 on the outer circumference of the joint. The circular arc surface 4-1 o...

The invention relates to a mold assembly used in a glass reinforced plastic wet winding process and a mold tool of the mold assembly. The mold assembly comprises a forming roller and the mold tool which is matched with the forming roller, wherein the mold tool comprises a roller joint of which the peripheral surface is cylindrical; the outer diameter of the roller joint is the same as that of the forming roller; a butt joint structure which is used to be matched with the end part of the forming roller to ensure continuous transition between the peripheral surface of the forming roller and the peripheral surface of the roller joint is arranged at one end of the roller joint; stop rods for blocking glass fibers which are correspondingly soaked by resin in the bypassing process or in the penetrating process are distributed on the peripheral surface of the roller joint along the circumferential direction at intervals; a gap for changing directions of the glass fibers which are correspondingly soaked by the resin in a bypassing mode is formed between two adjacent stop rods; and a fixed connection structure which is relatively fixed together with the forming roller in the using process is arranged on the roller joint. By the mold assembly and the mold tool, the problem that the glass fibers are easy to slip during variation of winding directions in the glass reinforced plastic wet winding process is solved.
Description
technical field [0001] The invention relates to a mold component and mold tooling used in the glass fiber reinforced plastic wet winding process. Background technique [0002] FRP wet winding process is usually used to make glass steel pipes. The mold components used in the FRP wet winding process include forming rollers and supporting shafts arranged at both ends of the forming rollers. The supporting shafts are connected to the corresponding power source. The support shaft turns. During the production of glass steel pipes, the operator needs to brush multiple layers of glass fiber layers on the rotating forming roller. The glass fiber layer includes glass fibers impregnated with resin. When the glass fibers impregnated with resin are wound to the end of the forming roller, It is necessary to change the winding direction of the glass fiber. During this process, the outer glass fiber layer is easy to slip due to insufficient adhesion between two adjacent layers of glass fib...
