Flexible Protective Element for Feeder Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mini riser systems for high-pressure automatic moulding lines do not adequately protect feeder sleeves from mechanical damage, leading to reduced casting production rate and quality.
Innovation Solution
A protective element with a flexible structure, made of a more flexible material than the mini riser sleeve, is introduced to absorb compression forces and prevent damage to the feeder sleeve during the moulding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a mini riser system is used in high-pressure automatic moulding lines, then casting production rate and quality are improved, but the brittle feeder sleeve is damaged by mechanical loads
Solution Approach 1:
A protective element made of flexible material is placed around the brittle feeder sleeve before the moulding process begins. This protective element absorbs and distributes the mechanical compression forces applied during high-pressure automatic moulding, preventing direct transmission of damaging loads to the feeder sleeve while allowing the mini riser system to function effectively
2Stability of the object's composition
If the feeder sleeve is made brittle to maintain shape, then structural stability is improved, but resistance to compression forces during moulding deteriorates
Solution Approach 1:
The protective element acts as an intermediary between the compression forces applied during moulding and the brittle feeder sleeve. It provides a mechanical interface that allows the feeder sleeve to maintain its brittle, shape-stable structure while the protective element absorbs the compression forces through its flexibility, preventing direct force transmission to the feeder sleeve
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The protective element enhances the moulding rate and quality by reducing the load on the feeder sleeve and preventing mechanical damage, thereby ensuring consistent performance in high-pressure moulding environments.
Implementation Method 1
due to the flexible structure of the protective element which is made of a more flexible material than the mini riser sleeve, the mini riser sleeve is prevent from being damaged by the compression effect applied thereon during the moulding process

AI summary
With the present invention, there is developed a protective element (E) suitable for use with at least one mini riser sleeve (1) which comprises a linear cavity (1a) through which a fluid material can be passed for the feeding process, at least one outer wall (1b), at least one base (1c), and at least one opening (1d) located at the base (1c) and providing the cavity (1a) to communicate with the outer environment. Said protective element (E) comprises at least one bottom wall (3) suitable for receiving the base (1c) of the mini riser sleeve (1) and being made of a more flexible material than the mini riser sleeve (1); at least one side wall (4) suitable for receiving the outer wall (1b) of the mini riser sleeve (1) and being made of a more flexible material than the mini riser sleeve (1); at least one aperture (3a) located at said bottom wall (3) and allowing a fluid passage between the opening (1d) and the outer environment.
