Fixing System Nozzle Reduces Feeder Sleeve Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mini riser systems for casting processes do not effectively reduce the mechanical load on feeder sleeves during high-pressure moulding, leading to potential damage and reduced production quality.
Innovation Solution
A fixing system comprising a nozzle with an expansion end that rubs against the cavity wall of the mini riser sleeve, reducing the load applied during moulding, and a housing for a damping material to further absorb mechanical stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a mini riser system is used at high-pressure automatic moulding lines, then the casting production rate and quality are improved, but the brittle feeder sleeve is damaged by mechanical loads
Solution Approach 1:
The patent introduces a neck piece as an intermediary component between the feeder sleeve and the mould cavity. This neck piece absorbs and distributes the mechanical冲击力 during high-pressure moulding, protecting the brittle feeder sleeve from direct damage while enabling the mini riser system to function effectively at automatic moulding lines.
Solution Approach 2:
The patent applies beforehand cushioning by designing the neck piece with specific geometric features that cushion the mechanical load before it reaches the feeder sleeve. The neck piece acts as a buffer zone that absorbs the shock of high-pressure moulding, preventing damage to the feeder sleeve before the casting process begins.
2Ease of operation
If the neck piece moves vertically during moulding, then it is driven into the cavity, but the load on the feeder sleeve is not reduced
Solution Approach 1:
The patent applies local quality by designing the neck piece with non-uniform cross-sectional areas along its vertical axis. The varying geometry creates different mechanical properties at different locations, allowing the neck piece to move vertically during moulding while distributing the mechanical load more effectively, thereby reducing the force transmitted to the feeder sleeve.

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 fixing system enhances the moulding rate and quality by directly applying the feeder sleeve on the mould model, eliminating size-related fixing issues, and preventing damage to the brittle feeder sleeve from mechanical loads.
