AI Technical Summary
Existing motor housing extrusion dies are inconvenient to use for feeding materials and have low strength, making it difficult to guarantee the quality and efficiency of aluminum profile processing.
The upper mold is designed with a cross-shaped and Y-shaped flow divider structure. The flow divider divides the feed hole into multiple flow dividers, which enhances the uniformity of feeding and the aluminum flow rate. Combined with the square discharge hole and the strip-shaped protrusion of the lower mold, the mold strength is improved.
This achieved a balance between uniform material feeding and aluminum flow, improved mold strength, and enhanced the processing quality and efficiency of the motor housing.
