Multi-chamber tire mold segmentation for puncture resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single-chamber tires are prone to damage and unable to withstand high-speed loads when punctured, leading to reduced service life and performance.
Innovation Solution
A multi-chamber tire manufacturing mold is designed with alternately arranged upper and lower holding plates, featuring tire periphery forming sliders, central mold posts, and isolating chambers to create multiple isolated chambers in the flexible portion, allowing the tire to maintain functionality even after puncture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single chamber is provided in the flexible portion, then the tire structure is simple, but when the chamber is punctured the entire tire loses air and cannot withstand dynamic load
Solution Approach 1:
The flexible portion is divided into multiple independent chambers (first chamber and second chamber) separated by a partition. Each chamber can be independently inflated and maintained. When one chamber is punctured, the other chamber remains intact and can still support the vehicle load, ensuring continuous tire functionality and safety.
2Reliability
If multiple isolated chambers are provided in the flexible portion, then the tire can withstand punctures and maintain high-speed performance, but the mold structure becomes complex
Solution Approach 1:
The mold is segmented into multiple independent components including upper and lower mold bodies, tire periphery forming sliders, central mold posts, and partition forming sliders. Each component can be independently adjusted and positioned to form the multi-chamber structure, allowing for flexible manufacturing while maintaining structural integrity.
Solution Approach 2:
The mold incorporates movable components such as tire periphery forming sliders and partition forming sliders that can be dynamically adjusted during the molding process. These sliders can be positioned and locked to create the multi-chamber configuration, enabling the mold to adapt to different tire designs while maintaining manufacturing efficiency.
3Reliability
If multiple isolated chambers are provided in the flexible portion, then the tire can maintain functionality after puncture, but the manufacturing process becomes complex
Solution Approach 1:
The manufacturing process is segmented into distinct stages: forming the flexible portion with partition forming sliders, creating the outer layer with tire periphery forming sliders, and assembling the chambers. Each stage uses dedicated mold components that can be independently adjusted, simplifying the overall manufacturing process despite the complex multi-chamber structure.
Solution Approach 2:
The mold components such as the upper and lower mold bodies serve multiple functions: they form the tire structure, create the chamber partitions, and provide mounting surfaces for the sliders. This multi-functionality reduces the number of separate components needed and simplifies the manufacturing process.

AI summary
A multi-chamber tire manufacturing mold, comprising an upper holding plate (11) and a lower holding plate (13) having an interval between the upper holding plate (11) and the lower holding plate (14); a tire periphery forming slider (16), a tire inner chamber forming slider (17), an upper mold block (121), a lower mold block (122), and a central mold post (18) are arranged in the interval; the upper holding plate (11) is connected to the plurality of upper mold blocks (121), and the lower holding plate (13) is connected to a plurality of lower mold blocks (122), forming an enclosed chamber (10); the tire inner chamber forming slider (17) is arranged in the enclosed chamber (10), forming a flexible portion chamber (101) and a partitioned chambers (171), such that a plurality of isolating chambers (25) are formed in the flexible portion (21); the openings of the isolating chambers (25) together with the tire periphery forming slider (16) form an enclosed chamber via process sealing members and fill the forming outer body (22). A tire flexible portion manufactured by the mold is provided with a plurality of enclosed isolating chambers, and can withstand multiple punctures and still meet the demands of high-speed run, thus the service life and performance of the tire are improved.
