Deep Drawing Die Ejector with Longitudinal Flanges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional die ejectors for deep drawing presses often result in aesthetic issues due to pressure marks on the plate and are complex and laborious to place, as they are individual elements requiring specific orientation and placement for each graphical element.
Innovation Solution
Die ejectors formed from a polyurethane or rubber body adopting the configuration of the graphical element, with a plurality of equidistant, identical longitudinal flanges on their upper surface, allowing easier and quicker placement and extraction by aligning with the horizontal axis of the plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional ejectors are located in the perimetric area around the cavity or flanges, then they can facilitate the separation of die parts, but they cause marks on the plate around the graphical elements which are anti-aesthetic
Solution Approach 1:
The ejector is merged with the central hollow area of the male part by adopting the configuration of the graphical element itself. The ejector body is shaped to match the graphical element's contours, allowing it to fit precisely within the central hollow space. This integration eliminates the need for separate perimetric placement while maintaining ejection functionality and preventing marks on the plate surface.
2Adaptability or versatility
If ejectors are formed by small independent elements inserted inside the hollow area, then they can adapt to different shapes of graphical elements, but they increase the complexity and laboriousness of placement
Solution Approach 1:
Multiple small independent ejection elements are merged into a single integrated ejector body that matches the graphical element's shape. The ejector features a unified structure with longitudinal flanges that correspond to the hollow area's contours, eliminating the need to manually position multiple separate elements. This reduces placement complexity while maintaining adaptability to various graphical element shapes.
Solution Approach 2:
The ejector is designed with a universal structure featuring longitudinal flanges that can adapt to different hollow area configurations. The flanges are arranged in a standardized pattern that can accommodate various graphical element shapes, allowing the same ejector design to serve multiple functions across different license plate configurations without requiring custom placement procedures.
3Adaptability or versatility
If ejectors are arranged in different orientations according to the form of the graphical element, then they can adapt to the shape, but they do not always allow lifting the plate with the same ease
Solution Approach 1:
The ejector employs asymmetric longitudinal flanges with different orientations relative to the graphical element's axes. The flanges are positioned at specific angles that provide optimal leverage for plate extraction. This asymmetric arrangement allows the ejector to adapt to the graphical element's shape while maintaining consistent ease of plate lifting through strategically positioned flange orientations.
