Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing application operation simulation devices struggle to accurately simulate the application of mold-releasing agents in die-casting dies, as they fail to account for multiple nozzles and cannot calculate the application time effectively, unlike paint simulation which assumes a single nozzle and focuses on film thickness.
Innovation Solution
An application operation simulation device that specifies nozzle positions and injection shapes, calculates interference points and application time, and displays a color-coded surface to visualize the application of mold-releasing agents from multiple nozzles, enabling accurate simulation and time calculation.

Engineering Contradiction Analysis
1Measurement precision
If a typical application operation simulation device is used for mold-releasing agent injection, then the simulation can be performed, but the device cannot calculate the application time required for cooling the die
Solution Approach 1:
The invention changes the evaluation parameter from film thickness (used in paint application) to application time (used in mold-releasing agent injection). The simulation device now calculates how long the spray device needs to remain at each position to achieve proper coverage, rather than calculating the thickness of the applied material. This parameter transformation enables the device to serve both paint application and mold-releasing agent injection scenarios.
2Area of stationary object
If the spray device is designed with multiple nozzles for mold-releasing agent injection, then the coverage area increases, but the simulation device cannot handle the complexity of multiple injection sources
Solution Approach 1:
The invention segments the spray device into multiple independent nozzle units, each with its own injection shape and trajectory. The simulation device processes each nozzle separately, calculating the injection shape and interference points for each nozzle individually, then aggregates the results. This segmentation approach allows the system to handle complex multi-nozzle configurations while maintaining computational manageability.
Solution Approach 2:
The invention merges the simulation results from multiple nozzles by combining their respective injection shapes and interference points into a unified analysis. The device integrates the coverage areas and application times from all nozzles to provide a comprehensive simulation of the entire spray device's performance, enabling evaluation of the combined effect of multiple injection sources.
3Measurement precision
If the simulation device calculates interference points for each nozzle separately, then the precision of application area calculation improves, but the computational time increases
Solution Approach 1:
The invention performs preliminary calculations by pre-defining the injection shapes and trajectories for each nozzle before the actual simulation runs. The device prepares the geometric models and interference detection algorithms in advance, so that during the simulation execution, the calculations can proceed more efficiently. This preliminary preparation reduces the computational burden during the actual interference point calculation phase.
