Slide Core Guide Rail Force Sensing for Small Mold Galling Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detection methods, such as acceleration sensors, fail to accurately detect galling and sliding failure in small-sized molds due to their reliance on impact detection, which is ineffective for small-sized molds.
Innovation Solution
A resin molding mold equipped with a load sensor, pressure sensor, strain gauge, or multiple load sensors attached to the guide rail of the slide core to directly measure the force applied during sliding, allowing for precise detection of galling and sliding failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an acceleration sensor is used to detect sliding failure, then sliding failure can be detected in large-sized molds, but minute galling and sliding failure cannot be detected in small-sized molds
Solution Approach 1:
The patent replaces the acceleration sensor (which measures indirect motion parameters) with a load sensor that directly measures the force applied to the guide rail. This mechanical measurement substitution enables direct detection of sliding resistance changes, achieving high precision detection applicable to both large and small-sized molds.
2Measurement precision
If a load sensor is installed on the guide rail to detect force, then detection precision for small-sized molds is improved, but device complexity increases
Solution Approach 1:
The load sensor is integrated into the guide rail structure, allowing it to serve dual purposes: supporting the slide core's sliding motion and detecting the applied force. This multi-functionality reduces the need for separate detection components, thereby limiting the increase in device complexity while maintaining high detection precision.
3Device complexity
If an acceleration sensor is used, then the structure remains simple, but detection capability is insufficient for minute galling in small-sized molds
Solution Approach 1:
The patent substitutes the acceleration-based detection system with a direct force measurement system using a load sensor on the guide rail. This mechanical measurement replacement provides reliable detection of minute galling and sliding failure, significantly improving detection reliability while maintaining reasonable structural simplicity.
