In the compression molding simulation under the previous simplified procedure, a simplified assumption has been made on the changes in the cooling channel positions between mold open and close for the convenience of users in quick modeling. Consequently, discrepancies in the cooling effect may occur, affecting the accuracy of the simulation analysis. If the behavior of the cooling channel moving with the mold can be incorporated into the simulation, it can more accurately reflect the actual situation, leading to more precise predictions of the temperature within the mold. The following demonstrates how to incorporate the mold movement behavior and its effects into the Moldex3D Compression Molding simulation.
Operating Procedures
Limitation
- Only supports compression molding process.
- Movable side and fixed side mold plates are required (mold plates needs to be simplified).
- Does not support Part insert / Mold insert movement.
- A matching mesh is required between the part, cooling channel, compression zone, and both side mold plate.
- Only supports standard cooling.
- In Moldex3D Studio 2024R1 version, the cooling time needs to be set to a minimum value (recommended value is 0.001 seconds)
Step 1: Model Preparation
Open Moldex3D Studio and select Compression Molding. Create or import a matching solid mesh that includes the part, cooling channels, mold plate, and compression zone components in the mold open state.
Step 2: Analysis Setting
Open the Process Wizard in Home Tab. Note that the compression time for the new compression process (Mold Plate type) already includes the cooling time, so the cooling time in the Cooling tab needs to be set to 0.001 seconds.
After completing other analysis settings for the compression molding simulation, select Transient Analysis-Ct F/P Ct W in the Analysis Sequence and submit the run for analysis.
Step 3: Result Display
Moldex3D can simulate the behavior of mold compression movement during the compression process.
The simulation of mold and cooling channels movement is incorporated into the analysis, resulting in a more accurate prediction of the temperature distribution within the mold.
With the new compression modeling, the cooling channels are positioned more comprehensively and closer to the part when compression complete, resulting in a lower temperature on the compression surface. In the simplified compression modeling, the movement of the cooling channels with the mold is neglected, affecting the cooling effectiveness.
Check the mold temperature distribution with clipping. In the basic compression procedure, the cooling channels on the movable side are kept farther from the mold, which fails to accurately represent the actual situation. In contrast, in the new compression simulation procedure, the cooling channels move along with the mold to the mold close position. Therefore, the cooling channels effect can perform properly, providing a better approach of the actual situation.
