Embedded Green Sand Mold Pressure Sensor for Continuous Strength Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the casting mold strength of green sand molds are inadequate, as they either fail to accurately assess mold strength or require individual measurement of each mold, disrupting the production process.
Innovation Solution
A green sand mold molding sensor with embedded pressure sensors in a plate measures the pressure applied to the parting plane, allowing for precise evaluation of mold strength without interrupting the production process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual measurement of each green sand mold is performed using a casting mold strength gauge, then measurement precision of mold strength is improved, but productivity deteriorates due to process interruption
Solution Approach 1:
The pressure sensor is embedded in the plate before the green sand mold molding process begins. This preliminary installation allows the sensor to automatically measure and transmit pressure data during the molding process, eliminating the need for post-molding individual strength measurements while maintaining measurement accuracy.
Solution Approach 2:
The patent replaces the mechanical casting mold strength gauge with an electronic pressure sensor system. The pressure sensor embedded in the plate electronically measures pressure and transmits data, substituting the manual mechanical measurement process with an automated electronic system that operates continuously without interrupting production.
2Productivity
If pressure sensor is embedded in the plate, then productivity is improved by enabling continuous monitoring, but device complexity increases
Solution Approach 1:
The pressure sensor is merged with the plate structure by embedding it directly into the plate. This integration combines the sensing function with the existing structural component, reducing the need for separate complex measurement apparatus and simplifying the overall system while enabling continuous monitoring.
3Measurement precision
If pressure sensor is embedded between the wall of the metal flask and the model in the plate, then measurement precision of pressure is improved, but ease of manufacture deteriorates
Solution Approach 1:
The pressure sensor is embedded in the plate during the plate manufacturing process before the plate is installed in the metal flask. This preliminary embedding ensures precise positioning of the sensor relative to the model and parting plane, achieving accurate pressure measurement while simplifying the final assembly process.
