Pneumatic Tire Mold Adapter for Solid Tire Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction of solid tires requires a different molding process than pneumatic tires, necessitating distinct molds due to the absence of an internal cavity in solid tires, which complicates the adaptation of pneumatic tire molds for solid tire production.
Innovation Solution
A solid tire mold is created by modifying pneumatic tire molds with annular adapters and flanges, allowing the use of upper and lower pneumatic tire molds to form tread and shoulder surfaces, and incorporating annular rims to manage rubber material during the curing process, enabling the adaptation of pneumatic tire molds for solid tire production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pneumatic tire molds are used for solid tire production, then existing mold infrastructure can be utilized, but the molds cannot properly form solid tires without internal cavities
Solution Approach 1:
The mold system is segmented into the original pneumatic tire mold components and separate adapter components. The adapters are distinct elements that attach to the mold to modify its function, allowing the mold to be used for both pneumatic and solid tire production by simply changing or removing the adapter component.
Solution Approach 2:
The adapter acts as an intermediary component between the pneumatic tire mold and the solid tire curing process. It mediates the interaction by providing the necessary structural modifications (flanges, rims, adapter receiving surfaces) that enable the mold to properly form solid tires without an internal cavity while maintaining compatibility with the existing mold infrastructure.
2Reliability
If different molds are used for pneumatic and solid tires, then each tire type can be optimized, but manufacturing complexity and cost increase
Solution Approach 1:
The pneumatic tire mold is designed with universal functionality to produce both pneumatic and solid tires. By incorporating adapter components with receiving surfaces and structural features, the same mold can be configured for different tire types, eliminating the need for completely separate mold systems while maintaining production reliability for each tire type.
3Adaptability or versatility
If pneumatic tire molds are modified with adapters, then solid tire production becomes possible, but the mold structure becomes more complex
Solution Approach 1:
The modification is segmented into separate adapter components rather than permanently altering the mold structure. The adapters are distinct elements that can be attached or removed as needed, adding versatility without permanently complicating the base mold structure.
Solution Approach 2:
The adapter serves as an intermediary that adds the necessary structural complexity only when needed for solid tire production. It includes features like flanges, rims, and adapter receiving surfaces that mediate between the simple pneumatic mold structure and the requirements of solid tire curing, allowing the mold to remain simple for pneumatic tires while gaining solid tire capability when the adapter is attached.

AI summary
A solid tire mold includes upper and lower pneumatic tire molds. The pneumatic tire molds have adapter receiving surfaces disposed radially inwardly. The pneumatic tire molds are joined at the pneumatic mold receiving portions. The pneumatic tire molds form tread molding surfaces and at least a portion of the shoulder molding surfaces. The solid tire mold also includes toroidal adapters, each having an annular pneumatic mold receiving surface, an annular solid tire curing surface, and a toroidal flange. The flange extends axially inwardly from the lateral wall toward an inner end. The inner end of the flange can be tapered. A toroidal rim extends laterally from one toroidal adapter to the other. The rim is disposed radially outwardly from the toroidal flanges in the assembled solid tire mold.
