Large-sized glass fiber reinforced plastic shaping mold, as well as manufacturing equipment and manufacturing method thereof

Abstract

The invention discloses a large-sized glass fiber reinforced plastic shaping mold and a manufacturing method of the mold. The mold comprises an inner support body, at least one fixed mold plate, at least three moving mold plates and a traction mechanism, wherein the fixed mold plate and the moving mold plates are arranged on the inner support body around the inner support body; the traction mechanism is used for driving the moving mold plates to move forwards and backwards relative to the inner support body; the fixed mold plate is relatively fixed with the inner support body; the fixed mold plate and the moving mold plates surround together to form a straight cylindrical mold core; and a plurality of reinforcing rib grooves are arranged in an outer side wall of the mold core. By utilizing the die, a glass fiber reinforced plastic tank can be conveniently formed by integrally molding reinforcing ribs and a tank body, with convenience in demolding; the manufacturing method comprises the following steps: adhering sealing adhesive, feeding a demolding agent, winding and shaping, curing and fixing the shape, putting into a support trolley, shrinking the mold, putting into a demolding device, dissociating the tank body and taking out the tank body. By utilizing the manufacturing method, the glass fiber reinforced plastic tank body can be conveniently formed by integrally shaping the reinforcing ribs and the tank body, and the demolding is convenient.

Description

technical field [0001] The invention relates to the technical field of FRP molding, in particular to a large-scale FRP tank body molding die, manufacturing equipment and a manufacturing method thereof. Background technique [0002] FRP tanks are widely used for their good strength, relatively simple molding process, light weight, and easy transportation and installation. Existing FRP tanks are usually formed by a winding molding process. By winding the glass fiber material soaked with resin on the outer surface of the cylindrical mold, the mold can be removed after the resin is cured and shaped to obtain the glass fiber reinforced plastic tank. [0003] The diameter of existing large-scale FRP tanks is often greater than three meters, and the length is several meters or even more than ten meters. The ring-shaped reinforcing rib is protruding from the inner wall to the inner cavity of the tank, and the existing mold is located inside the formed glass fiber reinforced plasti...

AI Technical Summary

Problems solved by technology

[0003] The diameter of existing large-scale FRP tanks is often greater than three meters, and the length is several meters or even more than ten meters. The ring-shaped reinforcing rib is protruding from the inner wall to the inner cavity of the tank, and the existing mold is located inside the formed glass fiber reinforced plastic tank and cannot be moved. For the convenience of demoulding, the existing glass fiber reinforced plastic tanks are all After the tank body is formed, the reinforcement ribs are assembled on the inner wall of the tank. Not only is the molding process relatively complicated, but the connection strength between the reinforcement ribs and the tank body is also low, which seriously affects the overall strength of the FRP tank body.
