Pivotable Mold Wall for Structured Part Demolding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mold frames struggle to efficiently remove molded pieces with structured or non-vertical side walls due to jamming issues, requiring laborious dismantling and are prone to mechanical and hydraulic failures, leading to increased costs and downtime.
Innovation Solution
A mold frame design featuring a pivotable mold wall attached via a multiple joint guide, allowing the mold wall to tilt or incline, enabling easy removal of molded pieces with structured side walls without the need for complex hydraulic or pneumatic systems, and allowing for efficient use of space and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional mold frames with fixed mold walls are used, then the structure is simple and stable, but molded pieces with structured or non-vertical side walls cannot be removed due to jamming
Solution Approach 1:
The mold wall is transformed from a fixed structure to a movable one through pivotable attachment via multiple joint guides. This allows the mold wall to dynamically adjust its position during the molding and demolding processes, enabling removal of molded pieces with structured or non-vertical side walls while maintaining structural simplicity.
2Ease of operation
If hydraulic or pneumatic systems are used to move mold walls, then molded pieces can be removed, but the systems are prone to mechanical and hydraulic failures
Solution Approach 1:
The mold wall utilizes its own weight and gravity through the multiple joint guide mechanism to achieve automatic movement during demolding. This self-service approach eliminates the need for external hydraulic or pneumatic systems, thereby improving system reliability by removing components prone to mechanical and hydraulic failures.
3Ease of operation
If complex hydraulic or pneumatic systems are installed, then molded pieces can be removed, but costs and maintenance needs increase
Solution Approach 1:
The complex hydraulic or pneumatic systems are extracted and replaced with a simpler mechanical multiple joint guide mechanism. This extraction eliminates the need for costly hydraulic/pneumatic components while maintaining the ability to remove molded pieces, thereby reducing manufacturing costs and maintenance needs.
4Ease of operation
If the mold frame is dismantled to remove molded pieces with structured side walls, then complete removal is achieved, but production downtime increases
Solution Approach 1:
The pivotable mold wall design allows for dynamic adjustment during demolding, enabling molded pieces with structured side walls to be removed without dismantling the entire mold frame. This maintains production efficiency by avoiding downtime associated with frame dismantling and reassembly.
5Stability of the object's composition
If mold walls are fixed to the supporting wall, then the structure is stable, but space utilization is inefficient
Solution Approach 1:
The multiple joint guide mechanism allows the mold wall to pivot between different positions, optimizing space utilization during both molding and demolding phases. The mold wall maintains stable attachment to the supporting wall when needed while efficiently utilizing available space through controlled movement, eliminating the need for excessive structural clearance.
