Component-temporarily holding member, and component mounting jig
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method for manufacturing foamed resin moldings requires labor-intensive removal of a component installation jig after demolding, which is inefficient.
Innovation Solution
A component-temporarily holding member with a temporary holding part that locks components to a forming die with a holding force less than the locking force, allowing the holding member to be separated without removing the jig, ensuring the component remains mounted after demolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a component installation jig is used to temporarily hold and mount components to a forming die, then the component can be securely positioned during foamed resin injection, but the jig must be removed after demolding which requires additional labor and time
Solution Approach 1:
The invention extracts the component holding function from the installation jig by using separate temporary holding members that are attached to the forming die. After foamed resin injection, these holding members are removed while the component remains securely mounted to the forming die through its own locking mechanism, eliminating the need to remove the entire installation jig.
Solution Approach 2:
The component mounting system is segmented into three independent elements: the forming die with mounting positions, temporary holding members for initial component securing, and the component's own locking mechanism. This segmentation allows each element to perform its specific function independently, enabling the temporary holding members to be removed without affecting the permanently mounted component.
2Stability of the object's composition
If a strong temporary holding force is used to secure the component during injection, then the component remains stable, but it becomes difficult to remove the holding member after demolding
Solution Approach 1:
The component is equipped with a locking mechanism that is activated in advance during the foamed resin injection process. As the resin cures and expands, it automatically engages the locking mechanism, securing the component to the forming die before the temporary holding members need to be removed. This preliminary locking action eliminates the need for strong temporary holding forces.
3Manufacturing precision
If the holding force of the temporary holding part is increased to prevent component displacement, then positioning accuracy is maintained, but the locking part cannot be properly engaged with the forming die
Solution Approach 1:
The temporary holding members use elastic deformation to provide flexible holding forces. The elastic portions deform to accommodate the component during mounting, providing gentle holding forces that do not interfere with locking part engagement. After the locking mechanism engages, the elastic members return to their original shape, maintaining positioning precision without exerting excessive force.

AI summary
To provide a component-temporarily holding member and a component mounting jig that do not require removal of a component installation jig after a foamed resin molding is demolded. In a component-temporarily holding member 3 having a temporary holding part 2 for temporarily holding a component 5 having a locking part 6 lockable to another member when mounting the component 5 by locking the locking part 6 in a component mounting position 8 of a forming die 4 for a foamed resin molding, the holding force of the temporary holding part 2 is less than the force with which the locking part 6 is locked in the component mounting position 8.
