Segmented Removable Shell Die for Cooling Without Strength Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dies for hot pressing suffer from reduced load-bearing capacity due to cooling water pipes being placed near the forming surface, leading to insufficient strength and temperature control.
Innovation Solution
A die design featuring a removable shell with temperature adjustment spaces and grooves that intersect the longitudinal direction of the die, allowing for temperature adjustment and strength maintenance through fluid distribution, with the removable shell being divided into multiple pieces for easy repair and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling water pipes are disposed near the forming surface to cool the die, then temperature control is improved, but the load bearing capacity and strength of the forming surface become insufficient
Solution Approach 1:
The die is divided into a die body and a removable shell that can be separated. The removable shell contains the cooling water pipes and temperature adjustment spaces, while the die body maintains structural strength. This segmentation allows the cooling function to be isolated from the load-bearing structure, resolving the contradiction between temperature control and strength.
Solution Approach 2:
The cooling water pipes and temperature adjustment functionality are extracted from the main die body and placed into a separate removable shell. This extraction allows the die body to maintain its load-bearing capacity while the shell provides the temperature control function through its integrated cooling channels and spaces.
2Temperature
If cooling water pipes are provided in the die to adjust temperature, then temperature control is improved, but the die structure becomes more complex
Solution Approach 1:
The cooling water pipes, temperature adjustment spaces, and forming surface are merged into a single integrated removable shell component. This merging consolidates multiple functions (cooling, temperature adjustment, and forming) into one assembly, reducing the overall structural complexity compared to having separate components for each function.
Solution Approach 2:
The removable shell serves multiple functions simultaneously: it provides the forming surface for the workpiece, contains the cooling water pipes for temperature control, and creates temperature adjustment spaces for precise thermal management. This multi-functionality reduces the need for separate dedicated components, simplifying the overall die structure.
3Strength
If the die is designed as a single integrated structure for strength, then load bearing capacity is improved, but repairability and maintenance become difficult
Solution Approach 1:
The die is segmented into a permanent die body and a removable shell. The die body maintains structural strength and remains in place, while the shell can be removed for repair or replacement. This segmentation enables easy maintenance of the forming surface without compromising the overall structural integrity of the die.
Solution Approach 2:
The removable shell is designed to be dynamically interchangeable with the die body, allowing it to be removed, repaired, or replaced as needed. This dynamic design enables maintenance and repair operations without disassembling the entire die structure, significantly improving ease of repair while maintaining strength during operation.

AI summary
A die includes a die body and a removable shell. The die body includes a supply flow channel formed inside the die body. One end of the supply flow channel opens at the surface of the die body. The supply flow channel is to be supplied with a fluid for temperature adjustment. The removable shell is mounted removably to the surface of the die body. The removable shell includes an outer surface that constitutes at least a part of the forming surface of the die. A temperature adjustment space is provided in the surface of the die body or in the removable shell. The temperature adjustment space is in communication with the supply flow channel. The removable shell is divided into a plurality of shell pieces. The plurality of shell pieces are arranged in a direction intersecting the longitudinal direction of the die on the surface of the die body.
