Mold Cooling Groove Layout for Uniform Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional molds with refrigerant passages formed by machining struggle to maintain uniform cooling, especially when molding components with height differences or curved surfaces, leading to inefficient production due to temperature inconsistencies in the molded product.
Innovation Solution
A mold design featuring a refrigerant passage that extends along the molding face as a groove on a support base, allowing for consistent cooling by maintaining a predetermined distance from the molding surface, and a method of manufacturing this mold by forming a groove on the support base and mounting the mold main body to ensure uniform cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a refrigerant passage is formed by machining in a conventional mold, then the mold structure is simple and easy to manufacture, but the cooling uniformity deteriorates when the work has height differences or curved surfaces
Solution Approach 1:
The refrigerant passage is changed from a linear hole to a groove that extends along the molding face. This dimensional change allows the refrigerant passage to follow the contour of the molding face, maintaining a constant interval even when the work has height differences or curved surfaces, thereby achieving uniform cooling across the entire molding surface.
Solution Approach 2:
The groove-shaped refrigerant passage is designed to locally adapt to the specific geometry of the molding face. By extending the groove along the molding face rather than using a straight linear passage, the refrigerant flow path is optimized for each local region, ensuring consistent cooling performance across areas with varying heights or曲度.
2Manufacturing precision
If the refrigerant passage does not maintain a constant interval from the molding face, then high-temperature portions remain in the molded product, but changing the passage shape to maintain constant interval increases manufacturing complexity
Solution Approach 1:
The refrigerant passage is transformed from a simple linear hole into a groove that extends along the molding face. This dimensional evolution enables the passage to maintain a constant distance from the molding surface even when accommodating complex work geometries, ensuring uniform temperature distribution in the molded product.
3Productivity
If uniform cooling is not achieved, then production efficiency decreases due to extended cooling time, but implementing uniform cooling design increases initial mold complexity
Solution Approach 1:
The refrigerant passage evolves from a simple linear configuration to a groove structure that extends along the molding face. This dimensional change enables the passage to adapt to complex work geometries while maintaining constant cooling distance, achieving uniform cooling that prevents high-temperature portions and allows immediate progression to the next production step.
