Description

Technical Field

[0001] The utility model relates to the technical field of mold manufacturing, in particular to a large-scale winding square groove mold. Background Art

[0002] FRP tanks are widely used. They are formed by winding glass fiber around the outside of a mold and solidifying it. After demolding, the FRP tank is obtained. However, the current FRP pipes are mostly cylindrical in shape, which is relatively simple and there is a lack of molds of other shapes. In addition, the site utilization rate of cylindrical tanks is low and the transportation stability is poor. Utility Model Content

[0004] In order to solve the above problems, the utility model first provides a large-scale winding square groove mold, including: a mold body, a telescopic frame and a base, the mold body includes four connected side walls, the side walls are arc-shaped surfaces, gradually convex from both sides to the middle, and arc-shaped corners are arranged at the connection of the side walls; the telescopic frame includes four telescopic rods, and the telescopic rods are respectively connected to the arc-shaped corners; the base is arranged below the telescopic frame, and the base is provided with a rotating shaft, which is rotatably connected to the telescopic frame, and the telescopic frame can rotate around the rotating shaft.

[0005] With such a setting, a new shape of mold is developed, the cross-section of which is nearly square, and can be used to manufacture square fiberglass tank bodies. The side walls of the mold body are curved surfaces, and curved corners are provided at the connection of the side walls, which is convenient for the glass fiber to be wound around the mold body, thereby increasing the fit between the glass fiber and the surface of the mold body and improving the product quality. The square tank body has higher space utilization than the cylindrical tank body, and is more stable and convenient for transportation. In addition, the telescopic frame can be telescopic and can be connected to mold bodies of different sizes, and has higher adaptability. Adding a base allows the telescopic frame to rotate on the base, which is convenient for the winding of glass fiber and increases work efficiency.

[0006] Furthermore, the telescopic frame is provided with a motor which can drive the telescopic rod to extend and retract.

[0007] Furthermore, reinforcing ribs are provided inside the arc-shaped corner.

[0008] Furthermore, a limit piece is provided at the outer end of the telescopic rod, and the limit piece cooperates with the arc-shaped corner limiter. BRIEF DESCRIPTION OF THE DRAWINGS
