Mold Base Selection Methods and Introduction to Huizhou Changhui's Services
I. Methods for Selecting Standard Mold Bases
- Two Selection Approaches
- Standard Application: Fully adopts the structural configuration specified by the standard, selecting parts within their defined dimensional ranges.
- Modified Application: Expands the application scope of the mold base by performing secondary machining on standard parts or omitting certain components to alter the standard structure.
- Specific Steps for Mold Base SelectionSelecting a mold base is a systematic process, primarily following these steps:
- Determine the Type: Based on the cavity/core structure of the part, ejection actions, and gating system, determine the structural type of the mold base.
- Determine the Series: According to the part's maximum dimensions, the range required for actions like side core-pulling, the layout of additional components, and cooling system requirements, select the plate size (which must meet the injection molding machine's installation specifications) to determine the mold base series.
- Determine the Specifications: Analyze the stress on the plates, perform strength and stiffness calculations, and determine the thickness of each plate and the length of guide pillars within the standard range to finalize the specific mold base specifications.
Other Considerations:- Once the plate size is determined, the dimensions of standard components like guide pillars and bushings can be referenced from the standard.
- Determine the spacer block height and ejector pin length based on the part ejection stroke and mold height adjustment needs.
- It is essential to verify that the total mold height complies with the requirements of the selected injection molding machine. Adjustments can be made by modifying spacer block heights.
