Description

Technical Field

[0001] This invention relates to the field of bicycle parts manufacturing technology, specifically to molding dies for mountain bike saddles or seat covers. Background Technology

[0002] With the increasing popularity of mountain biking, cyclists have higher and higher requirements for the quality of mountain bike components, especially for the saddle or saddle cover itself. Currently, mountain bike saddles or saddle covers are typically composed of parts such as the base plate, foam, sponge, and outer leather. For high-end mountain bikes, 3D printing is often used to improve the breathability and pressure relief of the saddle or saddle cover. This means that the saddle or saddle cover itself is directly printed using 3D printing technology. 3D-printed saddles or saddle covers generally have an elastic hollow lattice structure, i.e., a saddle. The surface of the saddle or seat cover is a hollow lattice structure, with no correspondence between every two layers of hollow lattices, creating a staggered shape. This provides excellent shock absorption, pressure relief, and ventilation, making it very popular among cyclists. However, 3D-printed saddles or seat covers are extremely expensive and have very slow production efficiency. It typically takes 24 hours to print one saddle or seat cover. Therefore, the market price of 3D hollow lattice structured saddles or seat covers is extremely high, with a single saddle or seat cover costing over 500 yuan, or even over 1,000 yuan, which cannot meet the needs of most cyclists. Utility Model Content

[0003] In order to overcome the problems existing in the background art, the purpose of the present invention is to provide a molding die for a saddle or seat body with a hollow lattice structure, so as to solve the problems of high price and low production efficiency of existing 3D printed hollow lattice saddles or seat bodies.

[0004] To achieve its purpose, the present invention adopts the following technical solution: a mold for forming a saddle or seat cover body with a hollow lattice structure, 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 forming mold for the saddle or seat cover body includes a lower mold base and an upper mold base hinged to the end of the lower mold base. The surface of the upper mold base is provided with multiple upper mold base protrusions, which are distributed throughout 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 mold cavity, which is substantially consistent with the shape of the saddle or seat cover body. Multiple lower mold base protrusions are provided in the concave mold cavity inside the lower mold base. The lower mold base protrusions are disposed on the surface of the concave mold cavity inside the lower mold base. The upper mold base can be molded with the lower mold base. The cavity formed by the upper mold base and the lower mold base is a concave mold cavity, which is used to form the saddle or seat cover body.

[0005] Preferably, the upper mold base has multiple upper mold base protrusions, which form a grid-like structure or a honeycomb structure, and the lower mold base has multiple lower mold base protrusions, which form a grid-like structure or a honeycomb structure.

[0006] Preferably, the upper mold base protrusion and the lower mold base protrusion are not overlapped when the mold is closed;

[0007] Preferably, after the upper mold base and the lower mold base are closed, the upper mold base and the lower mold base form a mold cavity, i.e., a concave mold cavity. The concave mold cavity is filled with TPU polymer material. After the TPU polymer material is heated and foamed, the upper surface of the TPU polymer material is attached to the upper mold base protrusion of the upper mold base to form the same grid shape or honeycomb shape as the upper mold base protrusion. The lower surface is attached to the lower mold base protrusion of the lower mold base to form the same grid shape or honeycomb shape as the lower mold base protrusion. Since the upper mold base protrusion and the lower mold base protrusion do not overlap, the saddle or seat body formed is a staggered hollow shape, i.e. a hollow lattice structure.

[0008] The beneficial effects of this invention are:

[0009] The saddle or seat cover body obtained by processing using the above-mentioned molding mold has a hollow lattice structure. Since the protrusions of the upper mold base and the lower mold base do not overlap, the saddle or seat cover body has a hollow lattice structure. Due to the use of mold processing, industrialized assembly line production can be realized, and the processing efficiency is greatly improved. For example, a set of molding molds can complete the processing of one saddle or seat cover body in one minute. Compared with 3D printing, the processing speed has been greatly improved. Due to industrialized assembly line production and lower processing costs, it also saves a lot of costs compared with 3D printing. Attached Figure Description

[0018] The following are specific embodiments of the present invention described in conjunction with the accompanying drawings, further illustrating the technical solutions of the present invention. However, the present invention is not limited to these embodiments. Specific details, such as particular configurations and components, are provided in the following description merely to aid in a comprehensive understanding of the embodiments of the present invention. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other.

[0020] like Figures 1-5 The image shows a molding die for a saddle or seat cover body with a hollow lattice structure provided in this embodiment, including: an upper mold base 100; an upper mold base protrusion 101; a lower mold base 200; and a lower mold base protrusion 201. The upper mold base 100 has a plurality of upper mold base protrusions 101 on its surface, which are distributed throughout the surface of the upper mold base 100. The lower mold base 200 has a concave mold cavity 202 inside, and the lower mold base 200 has a plurality of lower mold base protrusions 201 on its surface. The lower mold base protrusions 201 are disposed on the surface of the concave mold cavity 202 inside the lower mold base 200. The upper mold base 100 can be molded with the lower mold base 200. The cavity formed by the upper mold base 100 and the lower mold base 200 is the concave mold cavity 202, which is used to form the saddle or seat cover body.

[0021] Furthermore, the upper mold base 100 has multiple upper mold base protrusions 101, which form a grid-like structure or a honeycomb structure.

[0022] Furthermore, the lower mold base 200 has multiple lower mold base protrusions 201, which form a grid-like structure or a honeycomb structure.

[0023] Furthermore, the upper mold base protrusion 101 of the upper mold base 100 and the lower mold base protrusion 201 of the lower mold base 200 are not overlapped when the mold is closed;

[0024] When the upper mold base 100 and the lower mold base 200 are molded together, they form a concave mold cavity 202. The concave mold cavity 202 is filled with TPU polymer material. After the TPU polymer material is heated and foamed, the upper surface of the TPU polymer material is attached to the upper mold base protrusion 101 of the upper mold base 100 to form the same grid shape as the upper mold base protrusion 101. The lower surface is attached to the lower mold base protrusion 201 of the lower mold base 200 to form the same shape as the lower mold base protrusion 201. Since the upper mold base protrusion 101 and the lower mold base protrusion 201 do not overlap when the mold is closed, that is, the shape formed by multiple upper mold base protrusions 101 does not overlap with the shape formed by multiple lower mold base protrusions 201. Therefore, the saddle or seat body formed is a staggered hollow shape, that is, a hollow lattice structure.
