Composite Material Pallet Transfer for Uniform Die Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing composite material processing methods result in uneven temperature distribution in molding dies, leading to uneven solidification of the composite material, which causes insufficient pressurization and contact failures, resulting in voids and deteriorated component quality.
Innovation Solution
A processing apparatus with separate heating and cooling dies, using pallets to clamp and convey the composite material, and a temperature adjustment unit to maintain even temperature distribution in the cooling die, ensuring uniform pressurization and solidification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single set of dies is used for both heating and cooling, then device complexity is reduced, but temperature distribution uniformity deteriorates causing uneven solidification
Solution Approach 1:
The patent divides the heating and cooling functions into separate dies. The heating die and cooling die are independent components, each optimized for its specific function. This segmentation allows the cooling die to have a temperature adjustment unit that ensures uniform temperature distribution across its surface, preventing the uneven solidification that occurs when a single die performs both functions.
2Loss of time
If cooling medium flows through cooling passage, then cooling efficiency is improved, but temperature uniformity deteriorates due to localized cooling
Solution Approach 1:
The patent introduces a temperature adjustment unit in the cooling die that can independently control the temperature in different regions. This allows each area of the cooling die to be adjusted according to the local heat dissipation requirements, ensuring uniform temperature distribution across the entire cooling surface even though cooling medium flows through passages.
3Duration of action of moving object
If die temperature is high, then material solidification is delayed, but pressurization effectiveness deteriorates due to insufficient solidification support
Solution Approach 1:
The patent employs a temperature adjustment unit that monitors and controls the temperature of the cooling die. This feedback mechanism ensures the die maintains an optimal temperature that promotes timely solidification of the composite material, providing adequate support for pressurization while preventing premature solidification that would hinder material flow and densification.
