Description

Technical Field

[0001] The invention relates to the technical field of bicycle accessory production, in particular to a forming die of a mountain bicycle saddle or a seat cover body or a seat cover and a production method thereof. Background Art

[0002] With the popularity of mountain biking, riders have higher and higher requirements for the quality of mountain bike accessories, especially for saddles or seat covers. At present, the saddles or seat covers of mountain bikes are usually composed of bottom plates, foam rubber, sponges, outer leather and other parts. For high-end mountain bikes, in order to improve the air permeability and pressure relief of the saddles or seat covers, most of them are 3D printed, that is, the saddles or seat covers are directly printed out through 3D printing technology. The 3D printed saddles or seat covers are generally elastic hollow lattice structures, that is, the saddles or seat covers are made of 3D printed materials. Or the surface of the seat cover body is a hollow lattice structure, and every two layers of hollow lattices do not correspond to each other, which is a staggered shape, and has strong shockproof, pressure relief and ventilation and air permeability, and is very popular among cyclists. However, the saddle or seat cover body printed by 3D printing technology is extremely expensive and has a very slow production efficiency. It usually takes 24 hours to print a saddle or seat cover body. Therefore, the market price of the saddle or seat cover body with a 3D hollow lattice structure is extremely high. The price of a saddle or seat cover body is more than 500 yuan, or even thousands of yuan, which cannot meet the needs of the majority of cyclists. Summary of the invention

[0003] In order to overcome the problems existing in the above-mentioned background technology, the purpose of the present invention is to provide a saddle or seat cover body or a molding mold of a seat cover body with a hollow lattice structure, so as to solve the problems of high price and low production efficiency of the existing 3D printed hollow lattice saddle or seat cover body.

[0004] To achieve its purpose, the present invention adopts the following technical scheme: a saddle or seat cover body mold with a hollow lattice structure, which is used for processing and forming a saddle or seat cover body with a hollow lattice structure, comprising: an upper mold base, an upper mold base protrusion, a lower mold base, and a lower mold base protrusion. The molding mold of the saddle or seat cover body comprises a lower mold base and an upper mold base hinged at the end of the lower mold base, the upper mold base surface is provided with a plurality of upper mold base protrusions, the upper mold base protrusions are distributed on the surface of the upper mold base, the shape formed by the upper mold base protrusions is consistent with the shape of the saddle or seat cover body, the interior of the lower mold base is a concave model cavity, the concave model cavity is basically consistent with the shape of the saddle or seat cover body, the concave model cavity inside the lower mold base is provided with a plurality of lower mold base protrusions, the lower mold base protrusion is arranged on the surface of the concave model cavity inside the lower mold base, the upper mold base can be molded with the lower mold base, the cavity synthesized by the upper mold base and the lower mold base is a concave model cavity, and the concave model cavity is used to form the saddle or seat cover body.

[0005] Preferably, there are multiple upper die seat protrusions on the upper die seat, and the multiple upper die seat protrusions form a grid structure or a honeycomb structure; there are multiple lower die seat protrusions on the lower die seat, and the multiple lower die seat protrusions form a grid structure or a honeycomb structure.

[0006] Preferably, the upper die base protrusion and the lower die base protrusion are arranged so as not to overlap when the mold is closed; Preferably, when the upper mold base and the lower mold base are molded together, the upper mold base and the lower mold base form a mold cavity, i.e., a concave mold cavity, in which TPU polymer material is filled. After the TPU polymer material is heated and foamed, the upper surface of the TPU polymer material fits with the upper mold base protrusion of the upper mold base to form a grid shape or a honeycomb shape that is the same as the upper mold base protrusion, and the lower surface fits with the lower mold base protrusion of the lower mold base to form a grid shape or a honeycomb shape that is the same as the lower mold base protrusion. Since the upper mold base protrusion does not overlap with the lower mold base protrusion, the formed saddle or seat cover body is a staggered hollow shape, i.e., a hollow lattice structure.

[0007] Beneficial effects of the present invention: The saddle or seat cover body obtained by using the above-mentioned molding die is a hollow lattice structure, and because the protrusion of the upper mold base does not overlap with the protrusion of the lower mold base, the above-mentioned saddle or seat cover body is a hollow lattice structure. Due to the use of mold processing and molding, industrial assembly line production can be realized, and the processing efficiency is greatly improved. For example, a set of molding molds can complete the processing and molding of a saddle or seat cover body in one minute. Compared with 3D printing, the processing speed is greatly improved. Due to the industrial assembly line production and low processing cost, a lot of costs are also saved compared to 3D printing.
