Removable Marking Means for Tyre Tread Vulcanising Moulds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mold manufacturing processes for studded tires require frequent changes in insert components to accommodate different stud sizes, leading to potential damage and increased costs due to the need for repeated assembly and disassembly, which complicates the adaptation of the mold to various tire ranges.
Innovation Solution
A mold element with a removable insert and marking means that can be fixed to the insert body without disassembling the entire insert, allowing for easier adaptation to different stud sizes and reducing the risk of mold damage, featuring a rod that molds a cavity for the nail and marking means that can be independently adjusted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the insert and marking means are made integral and screwed into the housing, then the structural integrity is improved, but the adaptability to different stud sizes deteriorates and the risk of damage during assembly/disassembly increases
Solution Approach 1:
The marking means are separated from the insert body, allowing them to be independently removed and replaced. This segmentation enables adaptation to different stud sizes without removing the entire insert, while maintaining the structural integrity of the insert-housing connection.
Solution Approach 2:
The marking means are extracted as a separate component that can be independently attached to or removed from the insert body. This allows the marking means to be changed for different stud types without affecting the insert's connection to the housing.
2Adaptability or versatility
If the entire insert is disassembled to change marking means, then the adaptability to different tire ranges is improved, but the device complexity and time required for changes increase
Solution Approach 1:
The marking means are divided into a separate detachable component, allowing only the marking means to be changed rather than the entire insert. This reduces the complexity of change operations while maintaining full adaptability to different tire ranges and stud types.
3Adaptability or versatility
If repeated assembly and disassembly of the insert is performed, then the adaptability to different stud sizes is improved, but the reliability of the housing deteriorates due to potential damage
Solution Approach 1:
The marking means are segmented as a separate detachable component, allowing changes without removing the insert from the housing. This eliminates repeated stress on the housing-insert connection, maintaining housing reliability while preserving adaptability.
Solution Approach 2:
The marking means are extracted as an independent component that can be changed without affecting the insert-housing connection. This prevents damage accumulation in the housing while maintaining full adaptability to different stud sizes.
4Adaptability or versatility
If the insert is frequently removed and reinstalled, then the adaptability to various tire ranges is improved, but the loss of time and productivity deteriorate
Solution Approach 1:
The marking means are segmented as a separate component that can be quickly changed without removing the entire insert. This dramatically reduces the time required for adaptation while maintaining full versatility across different tire ranges.

AI summary
The invention concerns a mould element for vulcanising all or part of a tyre tread intended to receive nails for driving on ice. The mould element comprises a mould surface (3) capable of moulding all or part of the rolling surface of said tread. The mould element comprises an insert built into the mould element. The insert comprises an insert body (6) intended to be fastened into the mould element, a rod (7) intended to mould a cavity in the tread that is capable of receiving a nail, said rod being removably fastened onto the insert body, and marking means (9) capable of moulding a pattern onto the tread near the nail. The marking means (9) are removably fastened onto the insert body (6) by fastening means (11A, 11B, 11C).
