Hat-Section Forming Die Locking Block to Prevent Wall Buckling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing devices for components with a hat-shaped section face deformation issues during mold release due to pressurization from the pad and holder, leading to buckling of vertical walls, which requires complex mechanisms to inhibit deformation.
Innovation Solution
A manufacturing device and method that includes a block inserted between the pad and holder to receive and absorb pressurizing forces, maintaining the positional relationship between the pad and holder during mold opening and closing, thereby preventing compression and deformation of the component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pad and holder are moved during mold release, then the component can be released from the mold, but the component may be compressed and deformed due to pressurization from the pad and holder
Solution Approach 1:
A block is introduced as an intermediary element positioned between the pad and holder. This block receives and absorbs the pressurizing forces that would otherwise be transmitted to the component during mold release. The block acts as a mediator that decouples the pad-holder interaction from the component, preventing direct compression while maintaining the necessary mold release functionality.
Solution Approach 2:
The harmful pressurizing force is extracted from the force transmission path by introducing the block. Instead of allowing the pad and holder to directly pressurize the component, the block intercepts and absorbs these forces, removing the harmful effect from the system while preserving the essential mold release function.
2Manufacturing precision
If a floating block is used to limit pressurization, then component deformation is inhibited, but the device structure becomes complex
Solution Approach 1:
The block serves as a simple intermediary element that maintains the positional relationship between the pad and holder during mold opening and closing. This straightforward mediating structure prevents the need for complex mechanisms while ensuring accurate component formation and preventing deformation.
Solution Approach 2:
The force transmission system is segmented by introducing the block between the pad and holder. This segmentation allows the pressurizing forces to be independently managed and absorbed by the block, preventing direct transmission to the component while maintaining overall system functionality with simple, modular elements.

AI summary
A manufacturing device manufactures a component having a hat-shaped section as a pad and a punch sandwiching a center portion of a metal plate, and a die and a holder sandwiching both side portions of the metal plate are moved relative to each other in the upper-lower direction. The manufacturing device includes the die, the pad provided inside an opening of the die so that the pad is able to move relative to the die, the punch arranged to face the pad in the upper-lower direction, the holder arranged around the punch so as to face the die in the upper-lower direction and be able to move downwardly, and a locking block provided on the holder. The locking block is moved from a non-facing position to a facing position and inserted between the pad and the holder after mold closing and before mold opening.
