Rotational molding surfboard and manufacturing technology thereof

Abstract

The invention discloses a rotational molding surfboard and a manufacturing technology of the rotational molding surfboard. The rotational molding surfboard comprises a surfboard body, wherein the surfboard body is of a hollow structure with the front pointed and the rear blunt and is in the shape of a leaf, a streamlined concave portion is arranged on the top of the surfboard body, a plurality of convex tail fins are arranged at the bottom of the surfboard body, and a finished product of the surfboard is made through rotational molding hollow mold opening, material feeding, heating and rotation, forming and mold release, spraying, cooling, mold release and edge scraping processing. The rotational molding surfboard is simple in structure; because the rotational molding surfboard is provided with the tail fins, the effects that the surfboard is safe, durable and easy to operate can be achieved, production efficiency of the surfboard is improved, technological operation difficulty is reduced, and the purposes of standardization and batching are achieved.

Description

technical field [0001] The invention relates to a flow-guiding rotomolded surfboard with a tail fin and a manufacturing process thereof. Background technique [0002] At present, surfboards are produced and processed by repeated lamination and bonding of various materials. The materials used are uneven, the sealing is not strong, and the water absorption is high. The weight of the product is easy to increase after use, and it is easy to be damaged at the same time. The efficiency is very low, and at the same time, the technical level of the process technology operators is very high, and the product standards are different. [0003] In terms of the durability of surfboards, the existing surfboards seem to be very strong, but they are easy to break when going out to sea, and the service life is very short, mainly including glass fiber boards, foam core boards are easy to be scratched and easy to hit the board Broken boards will increase the cost of repairing the boards.

AI Technical Summary

Problems solved by technology

[0002] At present, surfboards are produced and processed by repeated lamination and bonding of various materials. The materials used are uneven, the sealing is not strong, and the water absorption is high. The weight of the product is easy to increase after use, and it is easy to be damaged at the same time. The efficiency is very low, and at the same time, the technical level of the technical operators is very high, and the product standards are different.

[0003] In terms of the durability of surfboards, the existing surfboards seem to be very strong, but they are easy to break when going out to sea, and the service life is very short, mainly including glass fiber boards, foam core boards are easy to be scratched and easy to hit the board Broken boards will increase the cost of repairing the boards. At the same time, the surface of the boards is easy to dent, broken branches, and easily damaged after impact. Inflatable surfboards are easy to scratch

[0004] In terms of safety, the traditional surfboard adopts a plug-and-play structural design, which is easy to hurt people during operation, and the front and rear sharp corners of the surfboard are also easy to hurt people

[0005] In terms of the handling performance of the surfboard, it is mainly the radian of the surfboard, the shape of the board, and the thickness of the edge of the board. Flip board; but most manufacturers make boards with small arcs to pursue high speed, but it is very easy to insert water or break the board. The large rudder is stable, but it is not easy to turn, and it is impossible to make movements. The small rudder is unstable and easy to turn. The weight and size of the board There is a little relationship, the lighter the better the movement, the heavier the higher the stability, which requires the user to be very professional in operation, which increases the difficulty of operation

[0006] In terms of environmental protection, surfboards on the market cannot be recycled, causing serious pollution
