Mold With Perpendicular Slide Groups For Overlapped Impeller Blades
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional impeller manufacturing requires separate molds for different shapes, and additional considerations for mold removal directions, making it inefficient for producing impellers with special blade shapes or overlapped areas.
Innovation Solution
A mold design featuring a first and second part that move in the mold opening direction, with slide groups having slide blocks that move perpendicular to this direction, allowing for the creation of impellers with overlapped blade areas and special shapes by positioning slide blocks within these areas to shape the blades effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional molds are used for manufacturing impellers with different shapes, then each impeller shape requires a separate mold design, but this increases device complexity and manufacturing time
Solution Approach 1:
The mold is divided into multiple independent slide groups, each capable of moving perpendicular to the mold opening direction. Each slide group can be independently positioned and adjusted to form different blade shapes, allowing a single mold to produce multiple impeller variations without requiring complete mold redesign.
Solution Approach 2:
The mold incorporates movable slide groups that can dynamically adjust their positions and configurations during the molding process. This dynamic capability enables the mold to adapt to different impeller designs by repositioning the slide groups, transforming a static mold into a versatile, multi-functional tool.
2Manufacturing precision
If conventional molds are used for impellers with overlapped blade areas, then the mold structure becomes overly complex, but this increases device complexity and manufacturing difficulty
Solution Approach 1:
The slide groups move perpendicular to the mold opening direction, introducing a new dimensional degree of freedom. This allows the mold to form overlapped blade areas by positioning slide blocks in the perpendicular dimension, achieving complex three-dimensional blade geometries without requiring equally complex mold structures.
Solution Approach 2:
The slide groups act as intermediary elements between the mold and the final impeller shape. By positioning these movable slide blocks within the overlapped areas, the mold can create complex blade geometries through the mediation of the slide groups, which handle the complexity rather than the overall mold structure.
3Adaptability or versatility
If separate molds are designed for different impeller shapes, then manufacturing flexibility is improved, but this increases loss of time and manufacturing inefficiency
Solution Approach 1:
The mold is designed as a universal tool that can produce multiple impeller shapes and sizes through the adjustable slide groups. This multi-functionality eliminates the need to design separate molds for different impeller variations, significantly reducing the time and resources required for mold design while maintaining manufacturing flexibility.
Solution Approach 2:
The slide groups are pre-configured within the mold structure with the capability to be adjusted to different positions. This preliminary preparation allows for quick reconfiguration between different impeller designs without requiring complete mold redesign, enabling fast adaptation to new manufacturing requirements.

AI summary
The present disclosure provides an impeller and a mold for manufacting the impeller. The impeller includes a plurality of blades, and there is an overlapped area between two adjacent blades. The mold includes a first part, a second part and a plurality of slide groups. The first part and the second part move in a mold opening direction. At least a portion of each slide group is located in the overlapped area, and each slide group has a first slide block and a second slide block, and a movement direction of the first slide block and the second slide block is perpendicular to the mold opening direction. By using that the movement direction of the slide group is perpendicular to the mold opening direction, the impeller with blades that have the overlapped area may be manufactured. The blades of the impeller may have a special shape.
