Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for transporting and handling mold halves in injection molding devices are inefficient, requiring rapid and flexible systems to manage carriers and ensure precise positioning for over-molding, especially when dealing with cleaning elements like bristle tufts that need to be embedded in the brush head.
Innovation Solution
A conveying tool system that allows for simultaneous transportation and positioning of multiple mold halves within and outside the molding device, using a base level supporting plate with sliding units and positioning units to facilitate direct contact and movement of mold halves, enabling efficient handling and integration of cleaning elements during the molding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conveying tool is used to transport mold halves into and out of the molding device, then the handling efficiency and precision are improved, but the device complexity increases
Solution Approach 1:
A conveying tool is introduced as an intermediary device between the external handling system and the molding device. This conveying tool includes a base level supporting plate with positioning units that can hold and transport multiple mold halves, serving as a mediator that simplifies the overall handling process while improving efficiency.
Solution Approach 2:
The conveying tool is designed with modular components including a base level supporting plate, positioning units, and sliding units that can operate independently. This segmentation allows each component to perform its specific function efficiently while reducing the complexity of the overall system through functional decomposition.
2Loss of time
If multiple mold halves are transported simultaneously using a conveying tool, then the transfer time is reduced, but the positioning precision becomes more difficult to maintain
Solution Approach 1:
Positioning units are provided on the conveying tool that pre-position the mold halves at specific locations on the base level supporting plate before transport. This preliminary positioning ensures that when multiple mold halves are transported simultaneously, each one is already correctly positioned for its intended operation, maintaining precision while enabling parallel transport.
Solution Approach 2:
The positioning mechanism uses a combination of mechanical positioning units and controlled sliding movement to achieve precise positioning. The sliding units can be actuated to move mold halves to exact positions, replacing less precise manual or粗放 mechanical handling methods.
3Productivity
If carriers are rapidly exchanged in the molding device, then the productivity increases, but the reliability of the transport system decreases
Solution Approach 1:
The conveying tool is designed with dynamic capabilities including controlled sliding units that can adjust their position and speed. This dynamic design allows the system to perform rapid exchanges when needed while maintaining controlled, reliable operation during transport, adapting the operation mode to the specific requirement at each moment.
Solution Approach 2:
The conveying tool includes self-positioning and self-alignment features that automatically ensure correct positioning of mold halves during rapid exchanges. The positioning units and sliding units work together to self-correct any positioning errors, maintaining reliability even during high-speed operations without requiring external intervention.
